Cermark F-20 questions
I just aquired a 60 size Cermark F-20 fuselage.....a few questions:
What is the wingspan (I need to cut a foam wing for it)
What airfoil? (Although I could go with just about anything)
Does anyone think a Webra 1.20 is too much?
All comments would be most appreciated.

RE: Cermark F-20 questions
I'll check the span on mine
Semi-symm. would be a good balance
The 120 would probably make you nose heavy... What can it turn? (Prop. and RPM)
I have a Tower-75 in mine and it flies great, gary has a Jett-90 in his and it smokes---
I always thought an OS-91VRDF would kick in there- if you could fit it...

RE: Cermark F-20 questions
Thanks guys....I got the fuse from my father-in-law...the wing is MIA. He had a Jett 90 in it, but I'm not about to spend that kinda money so I though I have this Webra sitting on my engine shelf. I may try to find a used DF engine and go that route.
I had actually kicked around the idea of using one of the Eppler semi-symmetrical airfoils as I don't plan on flying this plane inverted for prolonged periods of time.

ORIGINAL: Razor-RCU
I got my Tower-75 right here on RCU and it was $55
Gary: Is it really on 57"? Seems bigger...

So, of course, I re-checked it.....57 1/8" exactly. So there.....p'tui on you...

My F20
Hi Guys
This is one of my favorite airplanes she is fast and run like she is on rails.
Mine has a OS61 with a Mac tune pipe I have tweeked her to the edge engine and aerodynamics she is running 125mph with this setup.
All gear have doors and a APC 10*10 prop.
My Buddy has the sister ship with a Jett 90 that is now running approx 140mph. This without all the aerodynamic touches.
If you want to fly real turbine aircraft this thing is one of the best trainer for that. Even just to stay sharp with before you fly your turbine.
Best of luck
Ian

RE: Cermark F-20 questions
I started looking for a .77 or larger DF engine for this plane. It's missing the canopy so I should be able to put a curved header and a tuned pipe on it.
Also picked up an Outlaw at Toledo....have a YS 45 side exhaust for it......as if pattern wasn't enough of a money pit for me.
At what point should I think about going to an RCA meeting (radio control annonymous)
