Default out of the ordinary

after wrecking the airplane electronics i got in crashes i decided to put in some stuff i had laying around rather then buying more stuff. The thing is the esc is meant for a boat and the motor is for a car, the motor is a [link=http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=15195]motor[/link] and the esc is a 120 amp turnigy boat esc. The prop is a 7x5 by landing products. total weight of the plane plus a 3700 mah 25c 2s batt is about 1000 grams or 2.2 lbs

in case the link doesn't work motor is a 3650 2800 kv inrunner.
All numbers given are static.

amps at max throttle 51.87
the watts were 387.9
voltage didn't sag below 7.35

amps at just below half throttle 22
watts were 170

after 5 min of mostly half throttle with a few burst of full motor temp was around 115 at the end bell and esc temp was only 85-90 depending on where i temped it.

the plane is a mini magister by multiplex so im assuming it falls under the glider/trainer area.

Based on my calculations (2.2 x70 =154) i have enough power to fly at half throttle and enough power at full throttle to go near vertical.

CG was maintained at 2.65" behind the leading edge of the main wing by gluing nickles to the tail of the plane and putting the battery as far aft as possible.

so the question is do you guys see any problems with the flight? I know it is out of the ordinary but it seems like it should work.

Wind hasn't been cooperating so i haven't had a chance for a test flight and the plane ended up in this state from trying to fly in 15+mph winds in the first place so im trying to learn from that mistake.
