RSM and Brodak Nobler airfoil question

I'm thinking about getting a Nobler kit. I like the quality of both Brodak and RSM so my choice will come down to the wing. Between the Brodak and RSM Noblers, is there a difference in the airfoil? If so, which one has the thicker (blunter?) wing?

Thanks,
Ken

Ken,
The RSM Nobler is the later version (57)and has a thicker, blunter airfoil as well as a longer tail moment. Brodak's is an early 50's version and I think qualifies for Old Time. It has a thinner wing and a short tail moment.

Having buit both of them they both fly very well and are excellent kits.

Ken,
i agree with what Dave said. I have also built both versions and they both can be made to fly very well.

I would point out however that the Brodak version (1952 version) also has a considerably longer (2 inches if memory serves) inboard wing which makes it more difficult to trim to modern standards. Certainly not an insurmountable task but does require more effort and maybe an extra tab on the outboard flap to avoid hinging. (mine did)
As Dave pointed out this one has the advantage of being "Old Time Legal", with, of course, the loss of flap bonus points.

The RSM version is the "Green Box Nobler" and certainly the more popular of the two. This one can be made to fly with just about anything. If you need proof of that just look at the classic win posted by Bob Whitely at the NATS this year. Watching Bob fly his '57 Nobler can make one wonder why we fly anything else.
Truly a "Great" design. Of course the modern power plant (his has an Aerotiger 36), definitely makes a difference.

Third option would be a Gieske Nobler from UHP, Classic legal, and a good flier. If you decide on the Brodak kit, give me a holler. I can make you a deal on the one I have. Steve

Brodak? RSM?

Where does Top Flight fit in?

Top Flite produced the first Nobler kit in 1957. Refered to as the "green box" version because of the long green label on the box. Tom Dixon puts out, or used to, the Model Airplane News version, in a partial kit form. This is the 1952 Nobler. It is different than the Brodak version which is based on actual measurements of the restored, very first, Original Nobler, more commonly refered to as the 51 Nobler or Original. Top Flite later put out what is refered to as the Giseke Nobler, a refined version by Bob Giseke. RSM puts out a nice version of the Green Box (57) Nobler and Ultra Hobby Products of Dallas kits the Giseke version. Top Flite stopped production on the Green box and Giseke versions, I believe, could be wrong, in the late 70's. The only Top Flite "produced" version out there now is an ARF version of the Green Box Nobler. It has a few problems, all fixable it is a very nice mnodel.

Nothing against Top Flight. After reading about all the work people have to do to get an ARF ready to fly though, and my own bad experience with an ARF kit (not Top Flight), I won't buy another ARF.

cheers,

Great. The cottage industry will love you if you buy their kits instead. Try Builditright, Bluesky Models, UHP, Windancer, Tom Dixon, Exemplary Stunt Planes, Aero Products, and I know I have left some out. Short memory. These are excellent, well engineered kits, lots of experience and help available. Plus SIG, RSM and Brodak kits. I have said ARFs have a place, but their control systems are so retro 50's as to be foolish to use. Been there, did that.
