Let me point out one thing I forgot to mention.

I built a custom exhaust system for my 108 to get every bit of power out of it. My goal was to make an exhaust system to have enough volume and flow to allow the hot gases to expand and not limit the engines performance. Yet be hidden.

I did this because I noticed that many of the commercial in cowl exhaust systems look like they really reduce the volume of the exhaust system, (plus they are around $80) which for a 2 stoke is like a power limiter. As we know 2 stroke performance depends heavily on exhaust flow.

So I would be willing to bet that my 108 is not going to be much slower than a muffled larger 2 stroke engine CMP 109.

Again, these are things thate have worked well for me in the past.

If I thin out the wing and H-stab and V-stab later, I know it will be much faster.
