Okay guys, I'm going to throw a few different kind of questions at you. I'm just about to start building a modified Sig Kadet Jr, and need some input from those who have been there. I'm looking at modifying the wings by removing the 1.75" dihedral, adding 3" per wing for a total span of 54", adding 2.5X8" ailerons and flaps from the ailerons to just short of the cabin. I'm also lengthening the horizontal stab by one or two inches at the advise of a master pilot/builder. My questions are simple:
1) The plane is designed for a .15 to .25 and I have an O.S. Max .25 FP. Will this be enough power to get the plane off the water, or should I look at more like a .40?
2) Are the flaps I'm looking at adding something that will help or hinder take offs and landings?
3) I'm looking at getting a Futaba 9C, which has mixing abilities. Would it be worth while to program in flap functions for the ailerons?
HONEST OPINIONS WITHOUT CANDY COATING ANYTHING. I'm still at the point where changes can be made, so...................................
Here you go with no candy coating:
Mods are fine and should work nice. The flaps won't be necessary, but they should be fun to play with.
.25 FP will be perfect as long as you keep the plane LIGHT. If you do not keep the plane light then you will need more power which ends up with more weight and you are in a death spiral resulting in a lead sled plane that flys like crud. Keep it light! Don't use a .40.I
Get and use the nice radio. You won't regret it.
I don't know which floats you are intending to use on this plane, but I would highly recommend floats made from white styrofoam. It is easy to cut and make your own if you cant find some commercially made from this material. This is the lightest option.
