robby,
We did do some testing on the Twist 40 V2 and found that the engine was very well powered by it. I am not a 3D flyer, but it has plenty of thrust for it - definitely unlimited vertical. If you liked your Twist before then I think you'll like it on this engine. It's too cold here right now, otherwise I would have one of our more advanced pilots give it a whirl and report back. I think you'll be quite happy with this combo.
Hope this helps.

Has anyone considered mounting this on a profile? I am kicking around getting one of these engines and putting it in a kit built OMP Katana (old) or restoring a H9 twist 40 up in the rafters.

An OS 55AX weighs 18.5 oz with muffler. The 10cc weighs 22 oz with muffler and ignition, and you still need a battery or IBEC to power the ignition. The Tech-Aero IBEC weighs about an ounce, so your looking at 23 oz minimum vs 18.5 oz. for the glow. That could be a good thing (kinda) if your profile is tail heavy.
The plans state a weight of 4Lbsbut I remember my original one being closer to 5Lbs with glow and a 10 oz tank

My main concern is that if I purchase this engine that I can have a 3D airframe to use it on, I am not sure if the H9 Twist will give me that performance. Since I will be laser cutting a short kit of the Katana I can make changes (longer tail moment to help with balance, ect.) before I would build it.
I wonder if the H9 crew have tested this engine on a twist?? The twist would be as easy as a recover and minor repairs.
