Robart Pinned Hinges (Or is it dubro?!?)
How about oleo struts for the landing gear, 1/4th scale hardware, servos w/ 300oz in of torque rotating at 0.10 seconds for 60 degrees, separate servo for tailwheel, 12 channel synthesized PCM reciever, ten billion mAh Li-Po batteries with 6 volt regulator, temn million ounce fuel tank, and one-upping the engine you have now with a Zenoah GT80 Twin with dual tuned pipes?!?
Don't you like overkill?
Sorry, have a problem of posting weird posts.
PS I think a bigger fuel tank might help.
Sorry no offence, couldn't resist
Oh yeah, how about On-Board glow, fuel injector, rocket engines mounted on wingtips, a Voltmeter built in, etc
Now that will make the planey AT LEAST 10 lbs, but it will still hover with that Zenoah GT80!!!
