Nobler Questions

I'm new to this forum and have about a million questions I'd like to ask you guys. I'm 56 and am just getting back into C/L flyin after about 35 years, I started as a 12 year old with a Cox Curtiss P-40 that I learned to fly (or should I say crash) on. I progressed to building 1/2A balsa planes for my .049 engines after the plastic models gave up the ghost, wow! what a difference, these planes could fly. I just recently picked up a Cox PT-19 trainer at a yard sale and decided to show the grandkids how much fun it can be and have been bitten by the bug again. I'm in the process of building a Sig 1/2A Deweybird to fly with the kids, well I went to a great hobby shop in Landsdale PA. and saw a Nobler arf and had to have it. I plan to put it together and hold off flying it until I have some time with the smaller planes under my belt, I just could not resist it, it seemed like such a lot of plane for not too much money.
I also bought an OS-46 and am now wondering if I made the right choice. I don't as yet belong to any club and will hold off flying the Nobler until I join one, I would like to build it so I can use it in AMA stunt in the future. I can return the OS-46 and get a different engine for the Nobler or just keep the 46 for another project. Any recomendations? I'm a rank newby but I'm as excited as a kid.
Thanks
Jim

This would be better posted over in the "normal" CL forum, since it is a question, not a review.

I had a Nobler Arf review here on this review forum, but it disappeared after the last forum problem, and I guess it can't be found. Fortunately (for me at least), it was picked up and published in Stunt News.

In any case, you don't mention which OS 46 you have. The LA46 (and 40) are a bit heavy for this arf, although I think several people have reported good results using these engines. You usually need to add some tailweight. I powered mine with a Brodak 40, while a friend (Fred K.) has a Magnum 36 in his. I am very happy with my Brodak 40. I also think a lot of people have used the Fox 35 and the old OS 35S with good results.

If you have one of the ball bearing OS46's, then you may want to change engines.

For you I would actually recommend picking up a Flite Streak Arf along with an LA25. This is pretty cheap setup and may be a bit less costly than the Nobler Arf in the first few crashes.

Yes Sir, go for the flitestreak and save the nobler for better days.< Paul

That's a lot of engine, but not necessarily too much. Just be very sure that you balance the Nobler, you may need some tail weight to get the CG right, which makes all the difference in the world.

Have fun and enjoy!

I have an OS .40LA in mine, with a tongue muffler, metal back plate, and frount mounted needle valve. All these little things save a bit of weight on the frount end. After beefing up the engine mount rails, and a bit of beefing up the tail for stooge launching, mine balanced perfectly with no additional weight. The .46LA weighs a tiny bit less than the .40, but the .40 really handles my Nobler well. Also, my plane works well with a 10/6 prop, which gives a little more prop/ground clearance, whereas the .46 will need an 11" or bigger prop., and will be pretty close to the ground. I think I would consider exchanging for the .40.

Thanks everyone, I've got the LA-S version not the ball bearing model, the HS guy recommend it. It's going to be a while before my first flight, I plan to work up in size, I would like to put it together though. I read on this list somewhere about changing out the leadouts, did TF upgrade them in the later versions?, I have the 6oz. plastic fuel tank on the one I received.
Thanks again
Jim

I recall that at the Toledo '03 Expo, the prototype Nobler then being displayed for its introduction had an OS 46 LA on it. In any event, it was at least a 40 LA.

I'm simply providing info here; it could have been overpowered if indeed it were flown (don't know. Still, I recall one or two SSW posters putting a 46 LA on the ARF Nobler, and living to tell about it.

The engine shown in the Goldberg instructions is the .40/.46LA.I wouldn't recommend either,I think they're too heavy and will require too much tail weight,increasing overall weight.But neither one is "too much" power.The airplane will fly just fine as long it's straight and propped right.George actually liked them a little on the heavy side,and I've seen them fly quite nicely on a Fox .35 at 50+oz. The down side,in my opinion,is that the heavier the loading,the less forgiving the airplane.For training,stay light,and better yet as stated above,get a Flight Streak or Ukey and save the Nobler for later.

Incidentally,unless there's been a very recent change,you'll still have to change out the leadouts.This is easy.Just clip the stock ones behind the ferrule at the tip,insert the cut end in a short piece of 1/32 I.D.AL tubing and crimp or CA.Insert the end of the new leadout in the other end of the tube and crimp or CA.Unhook the bellcrank end and pull the new L.O.s in place.Join to the B.C.,and you're done.

Put a motor in the NOBLER that the engine mountd don't have to be cut down. Three motors I know fit Fox 35, OS 35 S, And a saito 40. The fox is a little light and the OS is perfect. See Ya NEAL

by any act, error, or omission, I have, intentionally or
unintentionally, displayed any breedist, disciplinist, sexist, racist,
culturalist, nationalist, regionalist, localist, ageist, lookist, ableist,
sizeist, speciesist, intellectualist, socioeconomicist, ethnocentrist,
phallocentrist, heteropatriarchalist, or other violation of the rules of
political correctness, known or unknown, I am not sorry and I encourage you
to get over it.

Other motors that fit without cutting. OS25FP Thunder Tigre 25 Pro and GP, The Thunder Tigre 36 and OS32 have the same mounting holes as the fox 35 but the mounts have to be relieved slightly same as the OS's and LA's
I'm using the TT25 Pro in both of mine. Dennis

Crash, ah, now there's a word I'm familiar with LOL, in fact if I recall that was my nickname one summer, I had just finished building a 1/2A model, my first with a tissue paper covered builtup wing, I seem to remember having trouble with the bellcrank sticking, but hey it was saturday and my buddies were at the field, you know the rest of the story. I kept that nickname until my buddy joe destroyed both his planes in two short flights, ha ha.

Use the LA40. Nice power plant, easy starting. No extra weight will be needed, if the stock muffler is replaced with a tongue muffler.

The model will almost balance perfectly.

Mike,
You are exactly right, as I wrote in an earlier post. I had intended to use a Stunt .35 in mine, but Bob Geiseke recomended a .40, and who am I to argue with Bob G.? If I had used the Fox, instead of the .40LA, I would have had to add an ounce or two of weight to the nose. I think each of these planes is an intividual, and you can't really tell about the C/G until you install everything. One thing is for sure, if you use one of the big LA's and a tongue muffler, the Nobler ARF will not necessarily be nose heavy.

Can you fill me in on that muffler, I'm not familiar with it.

Thanks, Jim
