Re: HKS engine conversion
Dave,
The plane weighs around 615 lbs. I found that my biggest problem was the prop. I was trying to use a 3-blade warp drive, and after talking with them (and reading an old post from Mnflyer) I realized that it was just too much prop for the smaller ratio gearbox. I've since converted it to a 2-blade version with better success, but need to get back to the project and finish it up.

Jerry at Greensky Adventures should be able to get these to you. He has a whole mount package, but he'll do separate parts too. Check here...

Re: HKS engine conversion
What reduction drive ratio do y'all have? My ROC's only about 550 FPM, but I have the 2.58 gearbox, not the 3.47.

Re: HKS engine conversion
I have the smaller gearbox too. Performance has been lacking. Sure wish I had the larger gearbox so that I could use a longer prop.

Re: HKS engine conversion
BTW rawheels, I'm running a lightweight 2 blade IVO in a model 2. And the 550 FPM isn't at gross but solo. Being in NH it's something that is much more of a constraint than in Indy (I lived in Anderson for 20 years so pretty familiar with central Indiana).

Re: HKS engine conversion
One thing I can say for the HKS - very low fuel consumption.
