RE: AXI 4130 w/Jeti 77esc?
Tango,
It is a difficult question to answer with certainty. Your Corsair power system delivers about 900watts with your 16x10 3-blade prop. This is about 86 watts/lb. and you will find that it flys with authority at only 1/2 throttle.
A similar power system on your 16lb Duane Habets Air Tractor Crop Duster will be about 56watts/lb. While this is a bit low, it should take-off fine and fly non-aerobatic scale maneuvers.
The trade-off here will be between saving cost and being confident about the design choice. Assuming a Cub-like performance on the Duane Habets Air Tractor Crop Duster, it should work.
The alternatives will be costly. The AXI 5320 motor or 5330 motor would be a better choice but I cannot recommend using them with the Jeti 77-amp ESC due to conflicting specifications. The next choice for a compatible ESC is double the cost or around $380.
Regards.
