The pipe is a helimax for 30 size helicopters actually. that os is a heli engine in there. it is blue print ported and has some good power for a 30. I still like the 45 in the magic better but mine was a enya45. It is a powerfull engine but the mid range was way too rich. Fast power is what is needed. The 32 was an experiment. rather than doing the right thing buying a new good 45. Luckily I got great results. I could use the horse power though for sure. My magic is killer light. 225 mini all around and a micro servo for throttle. the 32 size engine and no lead make it real light also NIMH save weight on the batt too. and I get 1200 mah. I also used some kevlar thread for tail guide wires. they work great and install in 5 min and is light light and strong as steel.
