Not an issue.

An F3A aerobatics competion ship with electric power has the same power and weight as a glow powered one. From what I have seen so far, the electric is more reliable. The equipment to get a largish electric model in the air is expensive but the running costs ("fuel", etc) is OK.

Electric pylon racers are very close to glow speeds.

Small electrics fly very well too and they are not expensive. Small planes are more sensitive to wind but, on the positive side, you can fly them in smaller areas, and they are easy to transport and store.
