Hi!
The problem with the GP GEE BEE R-2 isn't it's take of or flight characteristics...they are very good! The problem is landing it!!
Even if you have built it light as possible , moving the servos , receiver and batteries forward, taking up lightening holes in the side rudder, moving the tank forward, removing some of the glas-fiber where ever possible, choosing the lightest possible engine (15cc two stroke) making the plane weight out 5kg (5000g) sharp...despite this it still snaps fairly easy on landings!!!

I have been and still is, a pylon racer since 34 years, being used to fast flying airplanes, flying both F3D and Q-500 racers and having constructed many airplanes both pylon racers and others ...and despite this experience I find it difficult to land the GP GEE BEE R-2!

One problem with the plane is that the wings sits at 6 degrees positive to the stab, making landings hard to do due to the wing stalling at fairly low angles of attack.
I think that using differential throw on aileron will help, but I haven't tried it myself...yet!


As for my silencer ...it's just a mousse can! It's fasten to the firewall by 3mm plywood plates, siliconed to the bottom and top end of the mousse can.
A silicon tube goes from the steel (MVVS silencer) down to the mousse can.
Why I made this extra silencer was not to reduce noise, but to have a much more scale sound to the airplane!
We don't have any sound restrictions at our flying site!
