  • so just one question, why did you record from a computer screen and not just upload this video directly?

  • @dantaliansaint Old format on camera could not load it or I would have.

  • does it fly well, fast? with that engine

  • @phatgonk Yes it does fly very well with this engine sppeds are not blinding but good enough for me. This plane does not need to fly fast to be fun so this engine and plane work well together give one a try and see for yourself.

  • I wouldn't position myself in front of your plane while revving the engine. If the prop comes off your going to be seriously injured.

  • Been doing this for 25 years never had prop fly of yet! Could also slip on a bar of soap in the shower hit my head and die. Don't mean I plan to stop showering anytime soon.

see all

  • Is there anything you can do with the motor to make it quieter? 

  • That looks like it flies great and it looks like it still lands slow too. I have a Super Sportster 1.20 kit I want to finnish for next summer and planned on putting a Laser 2.00 V Twin in it I looked around and it spins a 16x8 at 8,700rpm what is your engine doing? is it similar also what wingspan and weight is it?

  • was that a fir eon the grass?

  • i have a balsa usa thunderbug 120 looks identical to your fourstar except yours is coverd like pimp my plane. could you take close up pictures of how the engine is mounted so that can have an idea of what i'm getting into or what modifications have to be done to mount that bad boy would reaaly aprreciate it

  • AWESOME!!! I really dig that airframe!  Killer conversion! I did an electric conversion, myself! Nice pilot!!!!!! ha ha ha ha ha

  • hi,

    what size prop are you turning?

  • sorry one more thing , was mounting fairy simple, iver never done a conversion, and also does it have the possible thrust with this set up to pull out of a hover some what?
