My brother flew petrol based RC planes about 20 years ago and now Hobbyking provides good cheap electric alternatives which has brought him back to the hobby to try out his first electric RC Plane.
Here is its first flight.
Is there a better set of wheels we can use on grass? Or is there a secret to taking off on grass that you can share with us?
