Just finished putting my Raptor 50 in a TT AS355 scale fuse. Build went pretty well and I had the maiden flight today. Haven't been this nervous flying a heli in a while! I've flown the Raptor for 2 seasons and decided to put it in the fuse this year. 2 general questions:

1. The tail pitch is not a smooth as it was before the fuse (feels a bit tighter when moving by hand when the power is off). Probably due to friction between the foam block that holds the boom in place and the tail linkage rod. Seems to be flying OK but I definitely hear the digital tail servo hum more than before. Is it worth me yanking the heli out of the fuse (a total pain in the butt) to open the hole in the foam for the tail rod or should it wear in over time?

2. I expected the engine to run hotter in the fuse so I set it up fairly rich. Without the fuselage, the temp of the engine was 165-185F. With the fuse, I'm running about 210F after a 5 minute flight. That's higher than I like to be but I hate to richen it up much more as it's pretty rich right now and bogging in the transition. Should I try to get it down below 190-200 or will 210 be fine (OS 50 Hyper)? I've got the rear windows open so airflow is about as good as it's going to get. Running 15% Nitro now.

Thanks!

I have been told to run 30% in mine. The oil content is higher and the motor will run cooler

I am going to build the tt ecureuil this winter. I was wondering about the engine running a little warm. I wonder if that metal fan with a lot of blades would help? I think heliproz sells it, maverikk hi flow.

Tom.
I built two 60-90 size Funkey fuses, one a L.Ranger, the other a Agusta. The Augusta weighs 14lbs.5ozs. This is with fuel, header tank,a full cockpit with 2 pilots, a patient on a strecher & a 6oz. digital camrea on board. This thing ran so cold in 90 degree weather that I had to lean out 1&1/4 turns. on 30% nito.
Both have Raptor 50 mechs, but I got a 30 grey gear & pinon in both. This came from advise of one club member.
I tried half 30%, half 15% mix but the power wasnt there when I needed it, { when its falling like a rock }. It also ran alot hotter.
My tail rod was sluggish, and servo was working harder, I had to take a driil bit & ream the hole in the foam bigger, it was a pain but well worth it.
I hope this small bit of advise will be help.
