Default Convert to electric`

Thanks for letting me in the forum, I am new here. I have flown gasers but now starting over with electrics. New to electrics so I built a J3 Cub by Great Planes, and I love it !!! It flies great, and no muss no fuss !!! I am now building a Great Planes P51 Mustang with retracts, got it because it said it could be converted to electric, but the parts it recommended seem to be unavailable. It would be a .40-.46 2stroke, or .60 to .70 4stroke, and I am wondering if anyone knows a good battery and brush less combo that will give enough power to get the performance I am looking for. Thanks for the help

Hi,
That plane should be around 6lbs depending on how you build it.

You could install this set-up for scale flight using a 5 cell lipo:

Or this one for more performance using a 5 or 6 cell lipo:

Thanks, Brian,

I looked at the site for Horizon Hobby, and that helps alot !!! I'm leaning more toward the Ni-Mh instead of Lipo, only because that is what I put in my Cub and it seems to work great. Do you have a preference of one over the other for any particular reason?

Thanks,

Jeff

Jeff,
LiPo packs have been the norm for years now for electric planes with brushed or brushless motors. They deliver more power and longer run times with less weight & size compared to NiMh packs.
