I wonder if this is that 70cc engine that someone made from using a motorcycle engine. It runs OK, but weighs a lot though, something like 4.6kg.
Not sure about power either.

It sounded OK to me, they were working on hovering the plane a lot and high alpha flying, so they would be down at idle and fast idle speeds and blipping the throttle a lot. Not flying WOT in this case.

It sounded to me like it was missing periodically, especially towards the end. Actually, it sounded more like a glow 4-stroke set real rich than a spark ignition gas 4-stroke. But what do I know.

Yes you could be right about it being on the rich side, but it seemed to be working OK though.

lavagrit, Did not mean to be a critic ....just want you guys to have success with your new 4 cycle engine. It may have a lot of appeal to non 3D flyers. Thanks Capt,n

@johnlu55 don't profit to SPAM this thread with your CRAP servos. just post more info of this engine.

@lavagrit cheaper for sure but now let's talk about reliability....chinese companies don't have a dyno so your engines power is often FALSE

I hope they put some care, and love into making the engines. Not just slap them together with a don't care attitude. It tends to cause the quality and attention to detail to suffer. That causes the engines to have stupid problems that should not have happened in the first place.

I'd be a little concerned with that intake assy. Would like to see somekind of support for it. Easy enough to fabricate something, but still.

This motor would fit the bill in the 55-60cc war birds market wich has been hurting for a good 4c gas motor. While the satios are nice, A good 70cc 4c single would fit really well in my war birds.

Do you have a us distribitor yet?

new video,
Four-stroke engine is more suitable for 3D-fly, faster throttle response and more linear torque curve.
