e-Electric Motors & Controllers > Razormotors RZ350 ROCKS on Hummingbird!

I have a Century/FEDA HB that I have been really enjoying for a while now. Upgraded early on to a 280bb motor that I have had absolutely zero problems with. Tried one of my older 16 turn Astro 010 motors but just would not cut it on 2 e-tec 1200mah Lipoly cells.

Today, I god an RZ350/Castle Creations Phoenix 10 combo. I went with the RZ350 instead of the heli version because it has a higher Kv (RPM/Volt) and I eventually want to go with a collective machine with a good head speed. I was a bit apprehensive to say the least, as I had zero reports of how this motor would work in this heli (or any other for that matter). This motor is tiny - smaller and lighter than either the Astro 010 or Hacker B20S.

I have only had one flight indoors (it too dark to go outside) but I can say that I have more power than the stock tail and a HH gyro can keep up with now. Power is instant, the Phoenix 10 is soooo smooth. Before with separates or the Hummingboard, I seemed to always be between a descending and climbing. With the P-10 it makes a world of difference.

Flew several 5 minute hovers and slow forward flight and the motor does get warm - but expect it from a brushless as the windings are against the outer case. The battery stayed cool throughout all flights so I can assume that I am using a bit less power then the 280bb which means I am putting more at the rotor where it matters.

I am using an 8-tooth pinion and would not really want to go larger. If the weather cooperates tomorrow, I will get a lot of stick time in and let those interested know how it goes.

Oh yeah, I'm jazzed!

The downside seems to be the cogging of the motor - when you chop throttle the tail swings a good bit. That and the torque when throwing the juice at it. I may make a longer tail boom and see how that goes.

Disclaimer: I have had a limited experience with this, so don't run out and buy one just yet until I have had time to abuse it.

Nothing else to report except I am a very ahppy camper! I managed to strip the 8 tooth so I am suiing a 10 tooth until I can get another 8. I can spin the heli with nothing more than a full throttle blast!

The power is very much welcomed now that I am into fast forward flight. The ability to quickly climb has saved my bacon on numerous occasions.

Flights are quite long with 2X1200mah E-Tech lipoly cells. Longer than with the 280bb and with more power on tap. Motor is warm after 20+ minutes of zooming around the back yard.

This is THE combo in my opinion for a Hummingbird. If you are using the stock blades, then an 8 tooth would be the only way to go (I have no experience with teh stock blades on this high speed motor so be cautious). But if you have not already done it, do the switch to Hornet main blades. You will thank yourself if you want to do any outside flying in forward flight.
