So Bigorneau do you still run the V8 in your E-racer? I thought that plane was a great idea then Shirley seemed to disappear.

It appears that Ballistic does not work with a constant speed hydraulic propeller. This would make the item of little use in the high performance, high horsepower applications. High hp being defined as 300 and up.

EDIT: I suppose an electric prop could be used.
If you are referring to AirMaster, I just reviewed one of their YouTubes last night (one of the ones that was filmed in Oshkosh of one of their salesmen giving the sales pitch). He said they had models that could handle "all the way up to 200hp", so I'm thinking that would be a "no" from them.

Can you post or send pics of your engine installation?
