Default brushless for big tiger moth 400

I have a big tiger moth 400 from gws and was wondering what brushless motor setup would work well with it. Any info would be appreciated. THanks

I would go with one of the outrunners from here:

There are charts with the descriptions to help with the selection. I have a 2812-1080 with a 10x4.7 APC prop and it pulls a 17 ounce plane very well.

Default RE: brushless for big tiger moth 400

I recently went brushless on my Moth since my 3c Lipo finally burned out the original motor. Performance is dramatically improved.
I opted for the E-Flite 400 4200kv motor and the ESC since I plan to use this in a 3D Tensor. Both work fine together. The only problem was that the motor shaft on the E-flite is only 2 mm and the original pinion or any GWS ones do not fit. This meant I had to change the gear box. Since I have an E-flight Tensor, I just used the E-flight gear box and all fits well and is very smooth.
I was using an APC 10x7 electric prop but found that the APC 10x7 slow flyer prop generated more oomph. Eventually I went to the E-flite 12x6 slow fly prop. Using a 3c Lipo the airplane appears to be overpowered and 25 min flights on full throttle are possible. I swapped the 3c Lipo and tried a 2c 2000 15C discharge pack I had and this is now the pack I'll stay with. Being a biplane, it is not necessary to hang on the prop or go ballistic so the 2 c provides more thrust than the original with or without the floats and I can fly most of the day on 1 charge.
It would be far simpler to have used an out runner but the cowl looks to be a bit narrow in the front.
