What are the only propellers is not built by modelers. Due attention was paid to the three blade. Why not try to install them on a modern cord “acrobat”? If Yes, will any benefit from the extra blades? Elaborate design, drew and made templates. Finally cleaned the sawdust out of the room evaporated the smell of varnish. The case for breakdown in air.
The first minute on track was a pleasant surprise to start the engine with that screw quite easily. And in flight? Every athlete-proteinic will appreciate the result, which gave the use a three-blade propeller: it seemed (although in reality it really only seemed) that subsided to a strong gusty wind. The model is not dispersed in the figures, smoothly tracing and drawing the whole system. Another surprise, and also a nice improved manoeuvrability.
Happy (feelings rarely accompanies training in such weather) “atletas”, waiting to stall the engine to put pilotasso. Twenty seconds, forty… This has not been the engine with the old tank worked for 7.5 minutes instead of 6.51.
