I've been running simulations on the 3d cad model and as is from factory there is not a lot left to improve upon to get more speed; really liking it... I've only got 80hp under the hood and 19deg pitch set on the Bolly; gives me 1000'/min at 80kt one up... is your's 100hp?

Yes, I have the 100hp. I have to say I installed the speed kit and Im happy I did. Its not a wow increase in speed but at this level a little improvement feels really good. Maybe 3-4 knots. The biggest jump was with the Duc prop (from a Woodcomp that provided dismal performance except on crazy short takeoff rolls). Cant imagine what this plane would do with CS. I did have a question for you. I do have a wheel fairing kit for the mono but dont know if the extra weight is worth the install. I have read that the shell is behind a turbulent area due to the cooling duct exhaust so the speed gain is nill. What do you or the group think? I think it would be worth the try because of the sealing of the tunnel but its installation sure will add some weight and complicate the airplane a little (which I try not to do). But I am curious.

From experience i would say the maingear cowl would reduce turbulence dB noise more than anything. Deleting the lower engine cowl chute improves forward performance with the loss of that 25kg lift and exit suction for engine cooling; maingear fairing works well in this scenario however the current shape is not optimum... Rear wing root fairings offer the best performance increase but only within a small AoA band with the flaps retracted. I have been toying with a STOL wing design which is proving very affective far.
