Questo e' quello che Tony Clark suggerisce riguardo al suo Piper J3 1/4:
The Piper is truly a multi purpose model. You can fly just like the full-size Piper with our Titan ZG 20 installed. That is if you have no ambition for glider towing, but you are satisfied with loops, rolls and stall turns. But you wish to be able to tow gliders, then the Titan ZG 38SC is a better choice. With the 38you can fly positive as well as negative figures with power to spare. Knife edge flying is unlimited. You can fly around with an almost fully throttled back engine, the model is then extremely quiet. Use a 20x10 propeller, this is the scale size. Should you wish to tow sailplanes that are more than 7 kg then the 45 is the engine. Fit the Titan ZG 62SL and with a 16 kg sailplane hanging on the line, is in a couple minutes close under the cloud base. But with the 62 you should only use full throttle whilst towing, otherwise the Piper roars around the sky ruining any scale effect.
