TwinHawk is a two motored version of the successful SkyHawk design. For lovers of the sight and sound of a twin motored aircraft there can surely be no simpler introduction. TwinHawk retains the good glide performance of the SkyHawk, longest flight in testing 35 minutes on 7x1000 NiCads.

The TwinHawk is easily hand launched and lands on it's integral skid.

"February 14, 2002... finally a calm, sunny, if cold day.
Prototype first flight demonstrated that there is plenty of thrust, great climb out at full throttle, still climbing at half throttle.
First flight of 17 mins.... second 21 mins."

"February 16th... first spring like day... a little light lift gives me a flight of 35+minutes on the 7x1000 NiCad. This is one lovely handling model."

 

#weight quoted is with 2 mini servos, mini receiver, 20 amp BEC speed controller,  7x 700mAh AA cells, tissue covered. Using 500AR cells, micro servos & Rx the weight can be further reduced.
