Would the bigger 800 watt motor only draw about 200 watts like the smaller one since it is spinning the same prop?
Bigger motor- more power is always better than being under powered and having to add dead weight to the nose of the model.
One of my recent creation, a larger Bi plane is a great example, initially fitted with "EF110" and model coming heavier than expected, I knew as soon as I hooked it up on thrust scale and E-meter it will be very marginal.
Minor upgrade to "EF160" did all the difference, still the same voltage but larger prop with abundance of power at 1.5 to 1. Easy fix.
E-meter with pull scale is easiest way to find out how good will it perform.
RPM/Current and Thrust checks using various props.
Easiest option was motor upgrade.
Massive improvement after motor upgrade.
In action - where it belong.
