I had one for a while. It was great. Much more powerful than the 37, but you feel the weight.

The reason I sold it was it was too smelly. I keep my nx4 in the trunk, and with the gas in the trunk my car always smelled like a gas station.

It was a pain to break-in, but just do it. I would let mine run in the yard while I was controlling it from my house with no blades or anything on. You have to keep blipping the throttle. And to idle a tank on a gasser takes hours. I did it watching the NFL draft. Just be patient.

The other thing I wouldn't run an aluminum case tail servo. The tail servo is right next to the fan draft for cooling the motor. The aluminum case is suppose to be a heat sink. But if the ambient temp is higher than the servo, it acts as a heater. I had a kst go bad on me like that. Just something to watch out for. Or if you must use an aluminum servo, I'd try to insulate it somehow.

T10 in my experience is bad for me.
Long Break-in and hard to setup.
Do not perform well in 3D, kind a slow or has no power due to its weight.

My experience has been really positive. I took the time to break it in very gently, and now it runs stronger than the 37, for double the flight time.

Breakin isn't that painful, I wired up AC/DC adapters for the CDI, throttle servo and RX (used failsafe so I could shut off my TX). It was so easy I did 15 min heat cycles. I ran Lawn Boy ashless for breakin, now running Redline, both at 10:1.

Converting to gasser is all up to you. I love the flight time, but I certainly understand that you have an investment in nitro engines/pipes. I did as well, but for me, it was worth it. But then again, I'm terrible at not spending money on this hobby. If you have other nitro birds, carrying 2 fuel cans might be a consideration for you.

I've been using racing gas without Ethanol, so no smell!

Check out the build thread over in the Gas Powered Thoughts forum.

Here's the break-in video using a test stand and props.
