Stinger 10
I have one with a Norvel 15. Hauls butt! All HS81's and a 555 Rx with a 250mA pack, REAL TIGHT FIT!!!! I know a dude that has an OS25FX on the front, and 2 mid size servos in front of the tail. It screams and balanced spot on. If I ever have another one it will get the 25 in it for sure.
