SV series.

Can someone tell me the difference between an SV-11, SV-12, SV22 and an SV-44? Also what does SV stand for?

SV= Stunt Vector
the series of Randy's SV line has progressed from the SV-11 (at least that was the first one that I saw being sold) which was a ST 60 ship through the newest higher numbered ships designed for the pipe engines. Some bigger, some smaller, muffler or pipe, etc., but most share the "SV" series of airfoils Changes to cosmetics and "shapes".
make any sense to ya?
Bill

I'd like to know that one myself (what SV stands for..)

I thought the S must be for Smith (Randy Smith). Maybe V is for Version? That's probably wrong as well.

SV stands for Stuntcraft Vector.

The SV-11 was not the first in the series, and there is no SV-44.

There are small aerodynamic differences throughout the series, along with changes in the fuse to accomodate modern available equipment and larger volume pipes. The SV-22 and SV-23 are the largest, with the SV-23's having slightly larger tail area.

The SV-24 is a piped 40 sized design, and has been configured into the Satona, Shrike, Dove, and Staris.

Hope this helps,

It does--thanks Curt:

And the SV-40 is a 40 non-piped version of the larger Vector or (sv-11 or 22). It is the basis for the Brodak Vector 40. The Brodak kit has a few cosmetic and construction simplifications.

It is a great flying plane.

Hi Curt

>SV stands for Stuntcraft Vector.

Ooops! Forgot about the "craft" part. Oldtimers set in.

>The SV-11 was not the first in the series, and there is no
>SV-44.

Correct, but I simply said it (SV-11) was the first one I saw plans for. (for sale) Did/does Randy have any earlier plans in the SV series for sale?

Hope to see you again, soon. Watch out for those Bumble Bees!

Wouldn't the first one have been the SV-1?

Thank you gents. Mine as I was told is an SV-40 then. I don't know where I came up with the 44 bit. Must have been some girl I used to know:p Mine was purchased from Bad Andy and is set up for an Saito .72. I have it stripped and ready to recover. It has those little half round tabs on the tips of the wings and elevators. What are those for??? I heard they were for better control.

NO no thats not how the name came about. Bill Rich and I flew together two to three times a week from the mid 80's till the mid 90's. He was flying Big Jim planes and motors. Around 1987 he and Randy got together and Randy built Bill some wings using his Stuntcraft airfoil. The first plane was the Vigilante a high aspect ratio plane.Then came the Tractor stunt and then the SV11.Bill got the numbers from Randy but used all his own design for the looks. The first two looked like New york planes.I got Bill to put the tab on the outboard flap and the paint theme he used over the years was mine also.Bill said he made up the name and it had no meaning.It just sounded good.The Vigilante was the first plane to have the Dragon on the nose that Bill used for many years.I always thought the Vigilante flew better than the Sv11 but it had to be built straight.Here is a picture of the first Vigilante in 1988 and the plane was brand new.Also here is a early SV11 with ST60 and my paint theme.I may be wrong about all this but we flew together all the time and I lanched the SV11 on it's first flight.That's what he told me back in 1990.Hope you enjoy the picture of a younger and trimmer Bill.I was a lot trimmer also.
I have added in another picture that is of the plane Bill had when he moved to Florida fron the north east.You can see where the SV11 side view came from.

FROM THE DESIGNER...

The SV-11 is the 11th plane in the Stuncraft "Vector" series of Airplanes. This series started at 700 sq. in planes and went up to 750..I realized I was going the wrong way so they went back to under 700 ( 695 to 675 for the big ships)
These started in 1975 at 590 sq. in I went to the
Larger 700 in 1976-77 and then to the 750 725 sq. in Stuntcraft,The bigger planes was when I expanded the wing system, and when really the SV airfoil wa s developed for larger planes
The 1978 725 Stuntcraft was Painted in Blue Silver red and
Painted with an angled aggressive scheme similar to Bill's planes, I have pictures of the 725 Stuntcraft from 1978 and will scan and post.

These are a few of the planes and names

SV10..Vectra late 1980s ( this is my plane nicknamed Dreadnought)
SV-11 is just called SV-11 ...... a laser kit
SV-12 the Intrepid..also longer one called Intrepid XL a laser kit
SV-14 is the Typhoon
The SV-15 is called the ASTRA
The Tempest 2 , Dreadnought 95 , Raven , Olympian , Classic , and others make up the rest to the SV-22
SV-22 which IS Called Exel
SV-23 is called the Katana...
The SV-24 thru mid 20s is a mid to large size 640 sq in series
and they go from there...

And yes most all of these are availible in kits Foam wood rib
o r plans

The Aerodynamics aspect ratio and tweaked formula for this plane came from the SV-10 That I built and designed in 1986, it was finished construction in 1990 and painted in 92....It was called the "Vectra" nicknamed Dreadnought..and also spawned the DREADNOUGHT 95.
It as the one before it used an outside adjustable tab...Ed Ruane had no part or input in me using this on my models..The reason I started using them was because of the complete inability to tweek
1\8 inch horns..and have them stay there. I also Got BIll to use them because I did not want him twisting on the flaps.

The earlier planes Bill Built and d flew also came from the "Stuntcraft" airplane and wing system and were my designs. These were all "Stuntcraft foam wing and stab components we cut here.
Bill Rich built and painted the first SV-11 in 1990..we worked very hard and long on color schemes..Both drawing them on paper and sending them back and forth to get the best looking scheme for the plane to "stand out" on the ground as well as in the air.
We did this for all of Bill's plane, As I wanted Bill to have a plane that looked very aggressive and really would show well in the air, As far as Ed Ruane designing the color scheme...this is the first I have heard of that. If Ed says he helped Bill with it I am sure he did, Ed has a lot of opinions and a lot of experience, and I'm sure was a big help to Bill.
Bill may have also been influenced by the The Slanted hard angles and some slanted Stars I saw on Ted Fancher's Paul Walkers and Jim Casale's airplanes,these are all
From the very late 80s to early 90s, plus A lot of other's planes,
(I used an Angled Color bar scheme on some of the first 9 SV airplanes, my 725 Sq in "Stuntcraft from the late 70s
That I flew up to about 1983 used this scheme, I will maybe scan and post pictures of it)
..these fit right in to the HARD ANGLE paint design and I think Bill decided to use them. I think he did a very good job with these planes

The plane Ed has pictured is a later model SV-11 and was not the first one..the first one I have here ( see below )and is the white front yellow rear Plane that has had the color scheme copied so much.

The later Orange - blue - white schemes has to do with the high visabilty and the fact that BILL went to Florida....Gators huh?

So far as the SV40 series of planes go they are also based on the "Stuntcraft" airfoil system but are not the same templates sizes or aspect ratios as the big ones..

The 40 sizes use one set of root trip ribs
Myself John Brodak and Curt Contrata , worked to develop and kit my Vector 40 design..it has Brother ships that use the same wing ..just in a different shape..)Tempest 40..SV-40,,DREADNOUGHT 40..These go well with Brodak 40 engines..AERO Tigers..Thunder Tigers.magmun or Any of the 35 to 46 FP LA type engines..This plane has been built and flown many times with pipes or mufflers.

The Larger mid size Vector was a late 80s design that is great for a ST 46...HP 40 ST 51 size power plants ...
This plane ( The Original 637 sq. in. Vector) was campaigned in the late 80s - thru 90 by Many people such as :
Dale Barry Tom DIxon , Jim Rettick , Dondi Garrison Rob Gruber 1 of The French FAI team members and many others. I prefer this size airplane even today.

The large 60 or plus inch size planes )SV 11, Intrepid,Tempest ll ) use a different root - tip template
And the newer 57 -58 inch ships (Staris, Satona, Shrike) use yet again another different size wing planform..

NONE of these planes are built only for a pipe or only for a muffler type motors, you can use either in any of them....as has been done many many times..

I hope I didn't ramble too much and I hope this clears up some info about the designs

I uploaded a picture of the first SV-11 that Bill built...You can see it is very similar to the previous 2 planes.
And YES the SV-11 did fly better than the ones before.
( I flew all the planes) It also handled the winds much better

Thank you Randy. This will surely help and prevent much of what happens down the road in twenty or so years when someone will ask the same question as has happened on the Nobler lineage and others of some fame.

Ty-I agree, it is nice to hear the accurate history on these designs. There was a post about the Nobler history that was very interesting to read, and Randy's post on the SV series also interesting.

John Since you and I belong to the same club and have flown together many times what you said cut me deeply. As you are to be the club president next year I will not rejoin as I don't want to be the butt of your crude jokes.I have been friends with Bill Rich for nineteen years and Randy Smith for fifteen years and your attack on me was unjust in every way.

Here are the three planes I flew in the 80's that Bill asked if he could use the paint theme.The grey plane with the rudders on the stab was the first one I used this paint theme on and it was built in 1984 and had a wing tab on it.The next two were built soon after and used from 1985 till 1992.All these planes had the adjustable tab on them but the adjustment is done very differant as shown to me by Stan Powell in the early 80's. I have seen adjustment tabs since the 50's and I have don't know who started it.All I said to Bill long before he ever built his first SV11 is why don't you use it.He did not use it on the Vigitante nor the plane that came before the SV11.I gave Randy credit for his stunt craft wings and the numbers. The SV11 that I showed has the dragon on the nose and I think Bill stopped using that by 1995 Bill has used this basic paint theme on at least half of his SVll planes.AS the years went on BIll gave me at least half of his planes and I flew them and passed them on to others.At least four of these planes are still flying.Eric V in Florida has two of them and one is from 1991. Good design Randy

The DRAGONS Bill liked so much were temporary TATTOOs
I think he may had ran out of them....BUt....you never know when he will search fo r more

My trim tab system is very differant than Stan's or the ones on Ed's planes, I see NO movable tabs at the ends of the wings.
Looks like the split flap method were you use a screw to hold the 2 pieces together...and you can loosen the screw and tweak a little more up or down trim in one of the halves.

I don't like moving the flaps at the extreme edge of the tips so I went about testing to see what would work best for me
I ended up figuring the sq in of flap area and adding this to the movable portion of the flaps, The last couple of inches at the tips were then made NON movable and the outboard was used as an adjustable tab to level the wings...
I would have them set this way even if they did not have any adjustment to them

Randy:

In regard to the wing leveling scheme, from the above its sounds like had it not been for the difficulty tweaking 1/8 horns, you would have preferred moving the entire flap for wing leveling.

Or after your development and testing, and knowing there is
at least one mechanical method for adjusting the flaps relative to one another, do you still prefer the wing-tip tab?

What do you see as the plus and minus of these two systems?

Thanks for the tutorial on the SV series....

Hi

I have done this both of these, and many other ways
I would not say I would now prefer to move the whole flap, I have found ZERO downside to moving just the tab, I use a 2-56 link so you can make movements of 1-128 th of and inch (1\2 turn )..that is very fine an d also very accutrate.

I think the only problem that might occur is if you had to deflect the tab an extreme amount eithe r up or down. I have seen and flown airplane I had to do thi s on, and was very surprised that there wasn't a hint o f adverse affect.
There is nothing wrong with moving teh entire flap to level....here is my suggestion for doing that..
Use split flap horns with an adjustment horn or whatever your favorite method is, and use this to raise or lower the flap...thi s gives you a very accurate and repeatable way to level.

SCOTT BAIR used this method in hi s ships, H e used an RC spilt aileron horn set up with 4-40 cleviss YOu could also use 2 balllinks

THE SV-11 did NOT come from one o f Bills old planes a N.E. plane or anyone else's plane
It is basicly a enlarged VECTOR with the newer Vectra (SV-10 )Airfoil. The Vector was designed years before the SV-11
as you can see below

Randy,

Im still confused. I thought the Dreadnought came after the SV-11 but if Im following you the Dreadnought kit is an SV-10 or Vectra right? Whats the Dreadnought 95 ?

Thanks

HI Rick

The VECTRA and the DREADNOUGHT are 2 differant airplanes. THe VECTRA had the nickname DREADNOUGHT and is 647 sq in, It was done in before the SV-11.
The DREADNOUGHT and DREADNOUGHT kit came after the SV-11 and is around 690 sq in. it is a bigger plane all around. The plane was a redesign of the VECTRA and made larger for simplicity and to carry bigger motors.

Thanks for your interest

Randy:

Love the dissertation on the SV series. My 630 Vector WILL fly this spring!

So where do the Nova / Novar ships fit into the SV history, and are there different flight characteristics (as compared to the SV's) you were shooting for when you designed them?

And what of Werwage's red P47 which he (in an interview with Bob Hunt on videotape) says has a "Randy Smith wing?"

Inquiring minds want to know.

HI Rick

I am glad to hear you are going to start flying again
Selling much ice cream now?

The NOVA and NOVAR were very similar to the SV airfoils
They are the STUNT CRAFT airfoil sections with 1\2 in more chord and just a little thinner. The planes fly so much like an SV it' s hard to tell them apart.
They are pretty popular designs but for some reason I don't see as many as you would think

The NOVA was design first, then THE NOVAR, these are both planes that came from mine and BILL Werwage's thoughts on the best planes we could make out o f them. and we were trying to see if another 1\2 inch of chord helped any in the wind..
The results were NO , the SVs already Handled excellent in all conditions, They were no worse or better.
AND we got a very good test in 1994 at the Lubbock NATs...very high winds there!!
STEVE MILLET has a very nice looking an d flying NOVAR

Below is one of the NOva s that flew AT Lubbock

Yes, Randy we do.

Oh yes we want to know!!!

I like the look and finish on this one. Nice work.

YES Tony I agree
that plane was Bill RIch's and really showed well in the air.
Very good paint scheme!
