I have one with a Moki 2.10. Proably about the same power as Brison 2.4. The power is good for 3D except for pulling out of hover. Hovers above 1/2 to 3/4 throttle. The 2.4 will be good but 3.2 will be ballistic. Ailerons are fine, mine does everything very well. It's a great plane, I highly recommend it.

The Saito 2.20 would be perfect in this ARF. DP loves low wing loadings and gas will raise that.
