Mine flies with an OS 108. This was my test version for CMP's 109. I have still have it, but when time allows will build my second one with scale corrections.
The only improvement to this one was an aluminum back plate with original plastic spinner, and a more secure engine mount system. The gear are a complete air retracts system to add the weight of the gear.
My new one will have electric retracts and a scale 3blade prop system, ect. All flaps were connected but not used.
When i get to it someday.
