Cobra Biplane
No one has replied to last posting. After checking plans I found tail section to narrow to mount servo on side, only 1 3/4 inch width at last former. I will mount servos under top wing near balance point. After laying down my GT 80 on top of plans I found I will have to move engine mount back 1 inch. Now thinking a 60 to 70 cc twin or single would make a better choice and add less weight. Also newer gas engines put out more HP than my old GT 80. Keeping engine mount in original place keeps my work load down and keep more room for fuel tank and miscellaneous items like batteries. I will now start looking for new or used engine on line that I can afford.
Waiting for shipment of balsa to arrive so I can finish latest project and start my Cobra. That all for now. Ken C.
