The mixer arm from e-flight is a bell mixer, not bell-hiller. The CP2 parts are bell-hiller. Parts list is back two or three pages. I just got the CP2 parts but haven't tried them yet. Futura has them and loves it. He's the reason I ordered them. Since the blade comes stock with a hiller head maybe the upgrade makes it full bell-hiller, don't know. I haven't read anything anywhere about anybody who tried the bell grips. They've been available for quite a while, just not under the e-flight name.

baddley--the tail boom is pretty difficult to get the CA to release. Some have been lucky enough to put debonder on the joint for about 15 minutes and gently wiggle it and it came free. The biggest problem is the debonder if spread too freely can melt the insulation on the tail motor lead. My lead was CA'd in the boom anyway. You will have to desolder your tail motor and, upon replacing the boom, feed the wire through the new boom back to the motor. Of course if you don't replace the motor mount, you'll have to debond that too. Good opportunity to upgrade to the direct drive tail.
