Dear modeller, you have just fulfilled your old dream - to own and fly a model that flies well, is easy to build, may fly virtually anywhere and thanks to its construction of expanded (foam) polypropylene (EPP) is virtually indestructible. A great inspiration for the Vespid model was the famous Toro 300. Vespid's space-saving dimensions enable you to fit the model into a pretty full family car in which you are just setting off for your holidays! Or you can organise a fun-filled pylon race in your garden, a local school gym or on the smallest available piece of turf in the neighbourhood. In any case you would use the indoor equipment you would otherwise leave idling during the summertime. The model is quite fast, very simple to build and its surface finish sets it apart from the rest. It is intended for a more experienced pilot, its construction (or rather the installation of RC equipment) is, however, an easy affair for any modeller.
Note: Why we tested the four-bladed (small) propeller too? The major drawback of a large prop is its huge torque and hence the reaction moment. As the model is relatively small, the effects of the large propeller torque would be commensurately brutal. To counter the reaction moment of the propeller by off setting the motor thrust line is in the pusher arrangement virtually ineffective! Therefore the small-diameter prop is almost mandatory.
what you will need
Power/control unit used on the prototype: Protech 4,8 g servos, Penta MZK 3 g receiver, MGM 7A controller, 3xLiPol 340mAh accumulator battery, 26 g, MPJ AC22/4-60D motor, 17g, 1xGWS 4,5/4 propeller. The flight weight of the thusly;-equipped model is 132 g.
