Korda C Stick I

My Korda “C” Stick already to cover. The weights so far: fuselage 14.0 gm./.49 oz.; wing 13.8/.48; stab 4.4/.15; rudder 1.7/.06; prop 6.3/.22; nose block w/bushing 4.8/.17 for a total of 45 grams/1.57 ounces. I hope to have a finished weight of about 2.5 ounces. I will cover it with Japanese tissue over 1/4 mylar and the prop will be fiberglassed. It already has 25 lb. nylon leader material glued around the edges. Good tip from Phil Klintworth, rough the nylon leader material up by pulling it through a piece of sandpaper folded over. It is then glued it to the prop edges with Ambroid, Duco or some other model cement. This will keep the blades from being nicked up. The motor will be twenty strands of 1/8 FAI and this might sound like a lot but this is a 17” diameter prop. This model was built from a Holman/O’Reilly short kit with excellent wood. I might build another wing and see if I can get the weight down a little bit. This seems a little heavy for the wing to me. It is prime building weather here in Lewistown, Montana, last night got down to 32 below zero and tonight it is down to 18 below at 9:15 p.m. 
Cheers, Karl Gies
