RE: CMP Hellcat
Just to let you know I added no extra weight to mine, was all done and went to check CG and it was right on. Saito 150 which by the way is lighter than a 120 and the 180 is even lighter than the 150 they just use the same block and bore it bigger which takes metal away. I have the battery all the way up at the firewall and only servos behind the CG is the rudder and elevator but they are only about 2-3 inches behind. Flap and Aileron servos are basically on CG. I am using a air cylinder for the tail retract but that is also on CG with a Fiberglass rod to actuate. Also used fiberglass rods for rudder and elevator and pull pull on steering. I feel mine is built just about light as possible I would of just had to add lead to CG if I had gone with a lighter motor. Guys don't shy away from the scale look it is more difficult to fly but not terrible, but it isn't for the novice. I flew my stock one for two years with well over 75 flights and felt it landed like a baby. If I had to do over again I wouldn't of done anything different. Thanks for the idea on the mods Luke turned out great and flies nice. Takeoff was normal I just let it runout and get good speed up before liftoff and landings are a little fast but you do have to keep on rudder with the gear being closer together. All in all I am very pleased and I am sure it will only get better I only have two flights so far.
