electric 40 pylon electric convertion
Another fun experiment was to take a old school nitro 40 type pylon racer ( formulla one ) And convert it to elecrtic WITHOUT loseing top speed Well It was dificult had to use a Nue motors 1521/2y/s brushless motor and a 2 , 5 cell 5000 mah packs in series to make a ten cell system The legal weight to race this plane is 5 pounds or under . well the batteries were total 3 pounds So it is not legal for raceing But it wild fun its top speed is close to and more (then in a shallow) dive to 200 mph NUTTY FAST It dose not turn tight like a light weight fomulla one but flight more like a typical turbine jet dose And similar landing carator The nue motor turns the 8 x 10 apc propat 24 000 rpm and the prop noise is ear piercing almost as loud as a nelson 40 on a pipe. But it works and it freeks every one out at my field a real jaw dropper
total flying weight was about 7.5 pounds Im not brave enough to pull full G turns the wings will probly fold and with 700 dollars of lipo battries on boad.... FOR GET it hahaha entire power train cost about 1200 dollars but wow what fun.
