I wonder about the price of one from China?

Looks good.

Probably a Gaokin. Decent engines though too heavy for me. They need a proven redrive.

If you don’t like the ace drives, fit a Rotax c drive to it.

It looks exactly like a canam 800-1000 engine. Exactly.

and the 1000CC @ 83hp also based on this thread on HBA : Ace Aviation Redrive: New model
Per that thread: 147 to 154 lbs with PSRU and all accessories (I assume that includes radiator and hoses, coolant?). So about equal in weigh to a full VW with full electrical system and starter. The PSRU would give an advantage in thrust for the Gaokin, esp at low airspeed.

A bit on the expensive side of a Gaokin Engine!

I didn't realize the original engine was so affordable. So, we're basically paying $5k for a redrive, engine mount, and propeller? Seems likely, and I assume the development/testing to assure they all play well together. Despite what some may say, getting a PSRU fitted and operating on any engine, but especially a twin, isn't a walk in the park. I'd want Chip to show me his math, his testing program, the problem/critcal RPMs, and any TV-related operating limitations. That's a big part of any value he is offering in the package price, I would hope. #### TFF ##### Well-Known Member How much do you think it would cost for you to make? They probably don’t net$200 once they sell one. Mount, prop , exhaust, and drive, if you subbed it out, would be in the ballpark. Once material, rent, labor cost, electricity, tooling, and time designed. Not many work for less than cost.

Every one of these drive designs bother me not having a strut to support the prop side of the pulleys. And the no TBO; chunk the engine and get another is great as long as they keep making them. Do you need to keep a pair and a spare just in case?

John Penry-Evans in thread ace-aviation-redrive-new-model, is in India producing redrives - probably too for this engine (don't know if for ChipErwin). Try to ask him for pricing

And, if you do, ask him about the torsional vibration modeling/analysis he does (hint: he doesn't. That's for the buyer to do, or not).
