| After building and flying the Vario XLV with a G260RC gas motor.I decided to build another XLV and convert it to an electric E heli after reading about Perry's XLV that he converted his XLV to an electric, which Perry is getting 20 minutes of flight time.
With the 20 minutes of flight time this makes it duable for the scale guys to fly with electric on the bigger helis, like the Vario R22.
Don't get me wrong I like the XLV gasser, especially after I convert the brush starter motor to a brushless type. And if you noticed I put insulation on the exhaust pipe which does two things, keeps the inside of the canopy cooler and it acts like a scavaenger pipe which tends to make the zenoah run better. There was another guy in the UK that was building a E-XLV but I think he is giving it up. But if you would like to see more, go to Perrys's gallery he goes by
Speedbird370 http://www.runryder.com/helicopter/t303021p1/ he has posted three movies of his XLV.
ESC will be a Jazz 63v
lipo 12S 10,600 mah--4 6S @ 5,300mah ea
motor Actro 40-4
The 40-4 motor is a 70amp motor and with 12S gives you around 3.56 HP
At hover it draws 30 to 35 amps which is aprox. 2.11 Hp which gives alot of head room.
The Zenoah G260RC stock is rated at 3.0 HP
The motor needs to turn 10,200rpm to give you 840 rpm for the main blades [per Vario]. Per Perry testing, at hover was 30 amps which gives plenty horsepower left.
The factory says you could go upto a 15S if needed.
At 70 amps you could use a Castle creation 85HV
