Janet:

If you insist on a small plane have at it. But setting one up for eledtric can be a real can of worms.

With glow power the engines are light enough, with sufficient power, that it's hard to make one that will not fly. Maybe not fly well, but fly. Electrics are not this way, they tend to be heavy and low powered unless you get some really expensive bits and pieces.

And that's why I still strongly recommend going with an already proven design.

Now. That being said, the Guillow's line includes some nice small planes that have been successfully converted to powered flight. They all come as rubber, as does your Convertible, but most are even smaller.

Good luck to you.

Bill.
