Now, lets ask another question:

I have heard (with all deltas & rear moutned engines), that you should:
-balance with a full tank
-move teh CG back to get it more stable, forward to get more 'aerobatic'

Since the tank is in the engine nacelle, balacing it with a full tank would be the 'worst case senario' as this creates a tail heavy plane with a full tank.

Moving the CG back.. Dunno about this, but I have heard others do this, to tame teh wild beast..

Any truth to this? thoughts? comments?
