Checking Thrustline / CoG
 
Anybody know any fool proof ways for checking up / down thrustline, one of my planes I just can't get it hands off inverted and keep moving the battery / CoG further and further back and it's now way behind the manufacturers recommended yet in comparison to my other planes still needs a shed load of down elevator to keep level light.

Any help much appreciated !!!!!

That trimming info is great! Maybe one day I will be able to fly without my plane trying to head to the ground every 5 seconds!

I am still very much a RC hobbyist only, not that serious but am learning that some proper trimming can make flying a real pleasure.
