Hello All

I run the original Ray N. conversion and I've had sometime to put on my Xera 4030-3Y.

My power setup is the following:

Kontronik Jive HV80(75% gov)
Xera 4030-3Y(20 tooth)
12s Thunder Power Pro Power 4400mah 45C packs

With my old Neu 1915H motor I had to wait about 10mins between flights because the motor would be very hot(about 170 with a temp gun) to the touch after a flight. I also found that Im not the only one that has experienced high temps with this motor on 12s with the older Ray N conv. Granted I could be using a better gear ratio...the motor still got too hot.

The Xera seems to have more power and stays cooler(about 130 after a flight). I can touch the motor no problem after a flight and have no problems with back to back flights...the best part is the motor is less expensive than the Neu

If you want a drop in upgrade for your Ray N. conversions definitally give this motor some consideration.

yeh! thats what I been saying for a while, a great up grade if you can find one! I had the 1915, actro 32-3, and I found the Xera 4030 2.5 Y better than those .

After a little research and running some numbers I am thinking about going with the Xera X4035/2.5Y instead of the Neu as I first intended. Any thoughts or reason why you went with the 4030 over the 4035 class motor.

I only need one!

Weight. Both the Neu and the 4030 weigh pretty much the same so I figured it would be a good comparison.

The 4030-3Y is more than enough motor for my 700E but the 35 sshould work well too.

hey, the 4035 Xera motor is a big motor, way bigger than the 4035 scorpion motor, it would compare with the actro 40 series motors, the 4035 works best in the A&P or heavy lifters than 3D

I'm Using that motor in my resurrected E Synergy.. A little different gear ratio. 11.27:1 but, on 14s 3850 TP 30C. Soon 3800 TP 45C. I was getting 5 min flights on the "Red headed Step Child" E Trex 700, and could have went more with the way i fly it..
I hear ya Carlo, heat was never a problem with it.. When i get the 2.5y back from E9 testing. I'll revisit the Dual Drive Synergy again.

Hi Carlo,

I ran the 4030-3Y in my 700e with a 16T pinion, 12s 5000 and the Jive 80+HV. It was a very sweet running setup that made very good power as well. The Jives don't need to be loaded as hard as the CC esc's in order for the gov to work well. I'd bet that dropping a tooth or two on your pinion will result in even cooler temps and longer flight times while still making acceptable power.

My conversion is the older Ray N conversion so I dont have pinion choices. But I am runninng my Gov at 75% which seems to work very well...so much more consistant in power.

Since the E setup is heavier than the nitro I cant get the umph I like at 1850 so I have to keep it at about 2K to get the preformance I like.

I very happy with this motor swap.

...now where was I, dh/dt = BS-dx/dt
I will fly you forever... till earth do us part

Thats not really an easy question to answer, but more than a scorpion motor and about the same as a kontronik motor.

I might have ended up with an Xera if I could have found one. My Neu is about 150 after a mild flight on 10S. You can't directly compare inrunner vs. outrunner temps because the windings where the heat is generated are well inside the motor on an outrunner vs. just inside the case as on a Neu. An outrunner will always seem to run cooler when this isn't necessarily always the case. Not saying the Neu is the better motor - I have no idea, but Neus get a bum rap for "running hot" when the problem doesn't really exist.

I think the bigger difference is an inrunner vs. outrunner difference. Outrunners have a larger amount of stored energy due to the design - more of a "flywheel effect". They may be less subsceptible to the initial bog and bog more slowly, but also will need to work harder to recover once they do lose RPM.

My Neu burns about 350 mA/Min in mild FF - no hard 3D.
