Following the success of the Greenley family of tugs and sport models attention turned to developing an electric version that matched the performance and towing ability of the Super Greenley. I am now pleased to present the Ampley. This model is 72" span so slightly smaller than the other models in the Greenley family but with the suggested powertrain has the same towing performance as a Super Greenley fitted with a Zenoah 62 with a tuned exhaust. The model follows the standard simple form of Greenley construction and as with the other models in the family, it is presented in 2 versions, one with a foam wing and the other with a built up wing.

Following several tests we have optimised the powertrain as follows

E-Flight 160 motor
Jeti Spin 77 speed controller
2 x 5S 5000mha Lipo's wired up to make a 10S pack
Graupner G sonic 20 x 10 prop

This combination will tow a 12kg glider to 1000ft in less than 1 minute and is capable of doing 5 of these tows on a single charge of the battery. as a sport model with this set up the model will fly areobatice for more than 30 mins.
