With my G90, I run a 13/8 apc. This is a very impressive setup. Been flying it nearly 4 years now.
The time frame alone is noteworthy

The trick to this stuff is the overall opinion. Yeh we have our own engines but the overall point being made is that you are under powered which is what you need to pick up on. After that the choice is yours.

I prefer Supertigers as a all around engine but do have Jett and OS also.
