It is very good. Interesting landing gear structure.

Yep,never seen that before.Although many of us broke their landinggear sometime.

Laozeng,will you sell this plane or is it just a one of a kind?

Keep them pictures coming!

I have not flown gas engines for decades, those 2 look hungry, and must need a servo for each one for throttle control. I wonder how he keeps them in sync.

Lots of power and range with a big tank, it is cheaper than a giant lithium batt, big Emotor, and probably 2 ESC's. We may catch up with the gassies someday.

Hello everyone, I can sell the aircraft to do this but I am worried that there will be far away from the difficulties other two engines throttle mixing has been set autopilot where a single engine flameout after another will be automatically increased to the maximum you can fly a single engine speed

I think an autopilot (Atto?) with airspeed scheduling could compensate for an engine out condition. If one engine dies the autopilot will advance the throttle on the good engine until the desired airspeed is met.
