I also have this setup (SD 35% Yak with DA100). Watch your weight if you want it to jump out of a hover. This is a large plane for a 100cc engine. Mine is almost 30 pounds. I don't run smoke and no pilot figure. I use a CF wing tube and CF propellor to save a litle weight. I'm using the supplied aluminum landing gear. You could save a few ounces here with CF also. I run 10 servos total - 4 JR ds 8411 (ailerons) , 4 hitec 5955TG (elevator and rudder) and two 421 (throttle and choke).

For batteries, I'm using three NiMh 2250 packs (no regulator, no matchbox, no powerbox). I may go to A123 cells to save some weight when these packs give out.

Mine came out a little nose-heavy. So consider putting the batteries toward the rear of the fueslage opening. Also, I have a few degrees of up-thrust.
