Engine for Herr J3 Cub 049 size??
Hi,
I'm considering to buy this plane for cool fun and want to install an electry motor....but I do not know anything about this engines...
so decided to post and ask some rookie questions...
Can someone suggest me a good electric engine for this plane (bellow US$50.00)?
And the speed controler?
Bateries?
Do I need gear box???
Better for me if you can pick thing out of Tower Hobbies inventory....
Thanks!!!!!!!,
Miguel

The Hacker A20-20L would be a good choice. NE Sail has a great deal on them with speed controller now. You will need a 3 cell 11,1 volt LI-Po battery 2100MAH. Or you could use a NI-MH pack. The HE-Cell have worked OK for me. On similar planes I can fly for over 30 Min per charge with a little throttle management. I have had good results with MP Jet motors. The 25-35-20 with 4:1 gearbox will do well or the 25-25-26 with 5:1 will perform great also. For the prop you can use 8X6 - 9X4.7.
