Barry thats a 1100ma 6v jr extra, and the tank is a 10oz- 8oz, got me so far? and i changed my cg from 5.25 to 5 9/16 and added a little more movement to my ele and rud(not much but a little)and it spins on axis now (realll pretty!!!!) and you guys would have puckered(like me) on my 1ft 11in slow inverted pass
and your a good man for helping the kid,what about the elderly?

did you say you like it Sergio, once you have it you will always need it(POWER!!)

Barry, i measured and its just about 1/4 in higher(hard to measure without removing engine) but what you want to do is make sure you get the bottom of the case as high as possible so the cowl will still clear it(or just touch it)
