RE: saito 220 reduction prop?
At my website, top bar propellers, you can download my prop calculator.
Your plane will fly well with a static thrust at about 75% of the plane weight.
fill in the gear efficiency of ~85% and your propeller dimension and find the rpm the propeller must make for the required thrust.
Then read the horsepower that the prop needs, and engine rpm will be prop rpm times 2.5.
Good luck.
