i have little plane i was givin, and i dont know what to do with it.

Its a wing with a stick for a fuse and tailfeather in essence lol. fully symetrical airfoil, look to be big enough i might could get away with full size electronics. 37" wing span. i beleive it was called an aerobat or something like it.

Basicaly my question is, what should i do as far as electronics? should i go electric motor or a small gas motor?what sizes(of each) should i look into for it? illd like to be able to fly in small fields with this(maybe a largish school yard. just curious thanks for any help
