Video: Depron 3D airplane with collective pitch prop

I recorded this video last Saturday night at our local indoor fly-in. This is Ben Batts flying his Lotus Depron 3D foamie with a collective pitch prop. Who says airplanes can't fly backwards?

I dunno, those reversals look a little, uh, sexual. Maybe he should hang out with some women?

Kidding, I am IMPRESSED

OMG
I've been flying at The Gathering Place in Greenwood, NEVER saw anything like this !!!
Plus the floor looks softer than the gym floor at TGP.

Where do I find info on the Lotus design and equipment ? Please :-)

Thanx,

Hi !
Excellent plane and piloting skill.
I tested this system on my R/C simulator but my transmitter still have a "springed" throttle stick so... it was very difficult !

Congratulations !

Question :
What are the AUW, engine, prop and lipo used please ?

Thanks

i doubt it's collective, more than likely variable pitch coupled with variable thrust. The most common system is the Mamo Upside Down System. There's a lot more info in the F3P forum.
