Engine cooling in FVK graphite glider

I have an electric FVK Graphite and would like information on specific
engine cooling requirements.

Model details are as follows:
Motor: Hacker B50-10s
Prop: Aero=naut 17x11
Batteries: 12 cells, CP1700 SCR
Speed controller: Hacker 105 3P-opto
Spinner: RFM Turbo

I have not yet flown the model and am concerned that the motor and speed
controller may get too hot without cooling slots.

Does anybody have prior experience with this model or general

A friend put a NACA style hole right above his Hacker and a rear cooling hole farther back on the fuse. You will not hurt the integrity of this bird...It is all Kevlar and Carbon.
