Delta-Cat, quick and cheap!

The latest issue of Radio Control Model Flyer contains a freebie plan of a simple catapult/throw delta model. It was so easy to build and required very little wood i had it built in an evening and a bit of the today.

I haven't flown it yet and i don't have the catapult built as in the plan. Don't know if it will be any good as a chuckie but i may slope it. The mag says its a fast flyer (looks so concidering the size), perhaps a little too fast for the local park, but i shall see.

I do fancy a bit o power to push around the sky but i can't decide on a good setup. Some specs;

AUW as normal- 148 grams ( including 32 grams Rx battery)
Span, 18 inches
Root chord of wing, 'bout 12 inches

For motor power system-

8.4 volt 250 mA nicad- 49 grams
GWS ips motor- 10 grams?
speed 300-20 grams? (actually sp 280 sounds better)
jeti 5 amp ESC- 7 grams i think

so i shall probably end up adding around 40-50 grams to the AUW, perhaps a little on the heavy side.

Any suggestions for powering this thing? props, motors, etc.
