Finished my Baby Flite Streak

LAST EDITED ON Apr-07-04 AT 05:26 PM (CDT)
 
Well I have finished the first of my new set of CL models, with inspiration from the Stuka Stunt works members I have finished the model, covering is the tissue supplied in the Brodak kit applied with Cellulose (english) dope, colours are PPG 2K car paints (deltron/delstar type material) with clear laquer to finish, air frame weighed 85 grams (2.98 oz) before dope, weighed 114 grams (4 oz) at the end of clear coat, flying weight ready to attach lines and fill with fuel is 195 grams (6.84 oz).
The TD 049 which I got off of Ebay seems to run nice on the Cox 6x3 prop, I am waiting for the lines to come before getting a test flight in over the Easter holiday.
Onto the original Flite Streak and Jr Satan's next.

Thanks for the help.

Barrie,
That is really a nice little Streak.

Thanks for the compliment, I sometimes like little wierd models, I am hoping it flies well, I have put my faith in the TD 049 as some advise I was getting pointed me towards the Norval engines, I think those engines are made in Russia and I have had real bad experience of mass produced Russian engines, I have seen a potential problem with the TD regarding centreing the prop on the crankshaft ie there is too much movement as the securing screw is being done up, I should pick up a little bush today which will sort this out, I wll detail it if it works.

As small as these planes are and weighing only 7oz the TeeDee should easily pull the plane. I've got a 9oz profile with a larger wing area I fly on 42ft lines that is almost overpowered by a Tee Dee and the same prop. A Norvel is designed to rev faster using a smaller prop, and will probably require 50ft lines.

Yes 7 oz is really not much weight for a TD to haul around, I am hoping for a good flight performance, may try and get some video of it flying as well.

The Norvels are fantastic engines. The engineering into them is far superior to the hundred or so Cox and spin-off like engines here in my shop, and (weight reduction per hp), hands down, the Norvels kick butt. Remember that the tech into our best fighters in Iraq today, mostly came from the MIG. I get a funny feeling about the engines coming from the former cold war place, but, results speak for themselves. Only my opinion. Nice Baby Streak!

Your little flite streak looks good. Your teedee will pull it good. I have a .061 norvel in mine and it goes like a rocketship on 42' lines but its lots of fun. Its one of my favorite CL planes out of any I have, big or little.

Thanks, I cant wait to fly the model.

I just have bad memories about Russian engines, although you guys do seem to rave about those Norvals.
Thanks about the Baby Streak.
Barrie

I might suggest trying an APC 6 x 2 prop to control the speed and give you ultra-high thrust at low speeds (hard corners and straight up flight portions). With such a light plane you probably won't be able to go much beyond the 42 ft that has been recommended, so speed control is what you will want. Definitely .008 cable lines, no string or .012s.

I will try and get some APC 6x2's, might be a bit of a battle with that one on this side of the pond, I would prefer it to pull stumps than fly like a rocket.

A set of the .008" 42'lines arrived today from the English Brodak agent, test flight over the holiday weather permitting.

On another subject what do you do to keep the props central on the TD's crankshaft as you are doing the screw up, in my veiw there is too much side play with the prop sitting on the mounting screw, I have had a small bush turned up that centres the prop hub into the prop driver, the size was wierd though we measured the hole in the back of a Cox 6x3 at 0.184 and the tiny little recess in the prop driver was the same surely that was meant to be 3/16", any how I feel happier that we have something in place to improve the alignment.

Thanks for your wise input.

If I am in a hurry, I use some fuel hose over the screw, and force it into the prop.

Stacked pieces of aluminum tube work too.

I vaguely recall that some of the RC flexible control rod tubes are a good fit.

Very pretty, GMA would be proud.
The TD ought to haul it around with no sweat- the original model used an Atwood Shriek.

Jake

thanks for your comments, now you have got me thinking how about building one with an Attwood are they obtainable at swap meets etc.

Barrie,

If you go with a radial mounted engine like the Shriek, you may want to consider the Baby Lightnin' Streak. It comes with a radial mount. Of course you could comvert the Baby Flite Streak from beam to radial mount also.

Barrie,

Yes. Also, not too long back MECOA (I THINK?) was assembling brand new ones out of left-over parts. GMA was fond of them from what I understood from him; using them quite a bit in FF, which was his first love.
The Atwoods were among the best .049s of the '50s era, along with the Holland Hornet. BTW: the entire Cox TD series was a product of the design genius of the late Bill Atwood.

I will contact mecoa to see what the story is about the Atwood's, might make an interesting basis for an engine collection ie 049 glow engines.
