HAHAHAHHAHAHAHA yeah ok .... well done

ok
but seriously... if i was to buy a 61 for a 50 size craft is there more of a chance of ....say ripping the wings off with the extra power ?????? or will the (just bought) 52 be ample for the craft ?
Well, you could probably rip off the wings with the smallest "recommended" motor if you tried. Going to a .61 on a .50 sized airplane will give more vertical. If you use the throttle to control your speed and prop the airplane correctly, you will have no trouble whatsoever. What I mentioned about maunfacturers being conservative, then a .61 might be the perfect choice. In large airplanes that are meant for fully unlimited "oversized" motors, throttle control is essential or the airplane WILL self destruct. Just check your balance and place your servos accordingly.
