Hi Ahmed! I can help You get in touch with a guy that makes this pipe here in sweden if you are interested.
However,I really dont understand the troubles everyone seems to have with servo sizes,I have Futaba BLS for rudder an elevator,whats the problem?
It works great for me and why install elevator servos in the stab? Use carbon rods and mount them in front of the engine inlet,no problem with heat at all..
Only issue with this model as far as I can tell is that it needs a lot of air pressure to get the nose gear in when airborne.
The reason that the takeoff was a little bit crappy in the video was that i had increased the elevator end point with 15% from the first flight,it made a lot of difference!
(a bit more than expected)
I was really nervous but it was a smooth plane in he air,looking forward to the next flight!
