in that case a glow trainer (provided your father has all the starting equipment, glow plug light, starter and starter batter) is going to be your best bet. you can easily get a trainer and engine within your budget! World Models Sky Raider Mach I ($70 from airborne) and a thunder tiger pro 46 ($80 from tower) it would be a perfect match and stay right on your budget give or take shipping.

however, since your dad doesn't fly, i would recommend that you get an instructer if not to fully instruct you at least to maiden the plane, trim it out, and give you an assessment of your capabilities. hate to see a newbie lose a plane particularly if on a tight budget.

another possibility is to take the engine from that big stick, i assume your dad is not flying that now, and put it on a trainer. that would save you even more money.
