Minimum flying area 12' X 16', or short hops in your shop. Takeoff roll is 3' at full throttle. Picture below.---OOOPS

Hi Dave,

Looks good as usual.. A real indoor flyer..

What do you mean by 7-5-1 reduction? is it 7.5 : 1?

I would like to try something similar, but my equipment is not suitable.. I am building actuators and pulsers, so maybe in short time.. (like 2 years at this rate :D)

Regards,

Bulent

Hello Bulent,
Long time no talk. It's good to hear frm you. You assumed correctly, the ratio is 7.5-1. The other is a typo. And, yes, this one is a true indoor model, although the wind dropped off last night, and I flew it for about 10 minutes behind a row of trees. Very ghostly looking.
Regards, Dave
