Okay, so try lighter 2200s....
Then it'll be right
BLUF, PZ designed their planes a certain way; when equipped with batteries that'll fit the compartment AS DESIGNED, their planes are the best flying models out there, bar none (that's why this thread is approaching 2,000 pages...).
If you have to alter the model to the point of cutting away significant
amounts of foam to fit certain batteries, etc, then you are going to have balancing issues, flight issues, etc. Which, BTW, isn't
Again, just my opinion. This plane is designed with beginners in mind, so therefore my comments are meant for those folks just starting out and I'm trying to steer them in the right direction. If you want to tweak your plane, go ahead. Tweak it to your heart's content. It's your money, it's your plane. All I'm saying is, if you have to tweak it, then it probably isn't right....just a casual observation.
Regardless, have fun flying your T-28, tweaked or not
