I fly both glow and electric (40 size conversions). There are advantages and disadvantages to each.

If you are going to try glow I strongly suggest starting with a trainer and an instructor. MOST glow planes are going to be noticeably faster than electrics (especially park flyers ) and are 4 channel (throttle, ailerons, elevator and rudder ) where many of the electrics are 3 channel. While they require a larger area to fly in, they handle wind MUCH BETTER than many electrics and do to their larger size, are easier to see. While many electrics are hand launched, many (if not most ) 40 size planes are ROG (or ROW if you are into sea planes ).
