With a span of 72" and a wing area of only 960 squares--I'd put a glow engine on that plane with a Cline regulator and fly it.
It's a bit on the small side for a gas engine. Actually, it's a LOT on the small side for a gasser.
Sell it and buy an 80" plane. Power it with a Brillelli 46cc.
You can buy an 80" Cap 232 from Blackhorse models for $300.

Or, for silly cheap, you can get almost the same thing from Giant Scale Planes for $200.

Sure looks like the same plane to me. Might not be, but it's close. I have personally NOT had good business relations with GSP, but lots of guys have. As always, it's your choice to do business with them and your responsibility to check them out and call them before you plunk down the Visa card. For $200, I'd probably risk it if I could at least get them on the phone and get a solid answer out of them on ETA and shipping prices. I don't like it when companies are ambiguous.
You can go to Scotts website and check out his conversions:

Here's the engines:

Click on that 46cc engine and look at the details of it. $395 for a 46cc engine that swings plenty of wood is a good deal. It's a Poulan conversion engine and they have an excellent reputation for being good runners. Scott has a pretty good reputation too. I haven't done business with him, but he sure seams to have a good rep. around RCU.
$400 for the engine
$200--$300 for the plane
$250--$400 for servos
(5 High Torque servos at about $50-75 apiece)
Miscellaneous hardware, batteries and switches $200
You could easily get your first gasser flying for about $1300.
I'd do that before I'd try and stuff a gasser into a 140 size plane with only 960 squares. The bigger plane will fly so much smoother and cleaner. It will handle the weight of the engine without sacrificing the wing loading.
Good luck in whatever you choose.
