In doing something like this the first thing you want to do is to look at the weights of the recommended motors.

You want to keep things somewhat in line with what the recommended combo weights are, though you do have a degree of variablility. However you don't want to put a 1lb motor into a plane that normally calls for a 2oz motor!

The Park 300 ( 1380kv ) produces 85 watts of power, weights .8oz (24g) and can sustain 7A with 9A burst, using an 8x3.8 prop.

The 2408 series come in almost twice as heavy at 50g or about 1.55oz. This may be OK however as you are adding less than an ounce to the nose, but you will need to shift the battery back a bit.


The 2408 1400Kv motor produces a max of 113.4 watts

The next one up the 2409 will produce upwards of 180 max watts, but you'll need a larger battery to drive it ofsetting the advantage a bit.,, however you'll also need to move the battery back a bit more, or shove things around to compensate for the weight.

If you go for the 2409 I'd opt for the 18T with the 9x4.7 prop combo to be able to pull the plane around the sky with great authority, while sacrificing a bit of speed for runtime.

Since the max loaded current is 20A with this setup, you'll need a corresponding 20C 3S Lipo pack of around 1000mAh... ( or larger 1200? ). This is bigger than they recommended setup, but you'll have extra power to go along with it.

The biggest change will be that the plane will have a higher wing loading.

The plane will have PLENTY of power this way.
