Hi!
Thank´s.
The DC-3 is covered with small strips of Oracover plastic film wet sanded on a sheet of glass then ironed to the fuselage/wing.
I use OS FS .26 and they are plenty ...the airplane nearly jumps into the air when I give full throttle.
The flying weight is 3,6kg.
I use 25-30 year old Swiss made (Gizendanner ) electrical retracts powered by a 4,8V, 400mAh NiMh battery (retract time is around 5 seconds). This battery also powers the landing lights in the wing and the tail and fin lights. Flaps are 4 piece, driven by two small Hitec 85 servos.
The propellers are my own made carbon fiber 10x5, 3-blades and my OS .26´s turn these with 9200-9800 rpm.
I use a 1000 mAh NiMH 4,8V battery as power for the reciever/servos. And I use a small JR 700 reciever.

Don't fall in the very common trap of going with too big engines...the reasoning for this is seems clear...nearly the same weight as with smaller engines...but remember that a bigger tank must be used...a bigger engine mount has to be used...sturdier construction must be used around the engine.....and so on and on. These things add weight and weight is your worst enemy in an airplane. last but not least is the fact that bigger engines has negative effects on how the airplane flies and behaves in the air.
I want my scale planes to fly "on the wing" ...not behave like a pattarn plane or a racer.
I enjoy competing in pylonracing, so I get my share of flying fast with other airplanes.

I have been very fortunate that an engine has never quit on me in flight . But I have been very carefull to set up the engines real well and I hope they will continue to run well.
Throttle action is instantanious when I give ful throttle and the engines nearly turn the same rpm at full throttle. I use two small Bluebird (10g )servos for the throttles to save weight. Fueltanks are custom made 110cc tanks, soldered tin tanks, set up with "Uni-flow " principle.
I use no silencer pressure. DC-3 flies like a big 2m sailplane and could nearly stand still in the air at idle.
