arrow laser
Benjo, I currently own and fly a laser arrow which is powered by a thunder tiger pro 46. It has been clocked by a police officer in our club at 113 mph and since then I have replaced the Master Airscrew prop with a APC which seems to have helped. I understand you are looking for more speed than this but perhaps this will at least give you a point of referrence. A Webra 50 should give you the performance you are looking for. This is a great flying plane. Have fun and be careful !
