Sweet, If i built mine again id use MKS DS450's all round too.
I have hyperion DS09's in the wing and an HD2212MG on the elevator, id expect an HS65 would fit in there easily though.
I measured up my wasp, outta curiosity, and its square, you musta got a friday arvo one
These are the throws in using at the moment, with a solid amount of expo as it very maneuverable, particularly at speed!
Spoilers 24mm up @IB edge
Aileron 22mm up, 9mm down @IB edge
Elevator 5mm up/down @centre
Throttle-Elevator .5mm up at full throttle @centre.
CG @ 52mm from centre LE.
Landings are a walk in the park compared to a speed400 pylon, its quite easy to drop it at your feet, with the spoilerons up it bleeds speed and lift quickly.
