e-Align T-REX 250-450-500-600 > The Ultimate Motor for T-Rex

I think the search for that ultimate T-Rex motor has ended. ggoodrum has posted a video of a test flight with Steve Neu's 1105/3y "Neu Motor" with 4s-1320 pack and 9T pinion. Check out that climb rate!

I got mine from tppacks.com.

has anyone tried the Neu with a TP 3s 2100?

Hope the US distributors will have those Align carbon blades here soon. Even at the $20 retail price it's a steal. Why are other manufacturers charging $50+ for blades these size? Are they really THAT much better?

By the way for those who are looking for the Neu motor mentioned above, I got mine from tppacks.com (Runryder sponsor so don't give me crap about advertising). They're running a special on the motor with TP 4s-1320 pack combo right now.

Video looks good. Looks like it hauls ass. I'd be curious what the inverted climbout looks like--to see how symetrical the pitch settings are. Mine climbs out ok upright but is pretty fast inverted. Really want to qualify how good the motor is before changing or purchasing.

How are you guys rating your "best motor"? Climbout?
I am running a B20-15L on a 3 cell TP1320, and performance is good/great. It does NOT have an explosive climbout, but its light, and can keep up with the flight moves that I am capable of putting it through without the motor even getting warm. Loops, consecutive rolls, multiple piro flips, inverted flight, etc. Even some tic-tocs. Not hard core 3D, but demanding heli flight nontheless. I am certain with collective management, and alot more practice, that I can make this heli do a great deal of 3D moves with my current setup.
I am curious about more power, as it can make things easier, but it would be nice to know how people are rating motors. Climbout is not everything. Keeping power through multiple tricks (torque) without crazy amp draw would be a much more worthwhile rating.

Yeah Im not after huge power, just something that will pull enough collective to do tic-toc's comfortably and pull out of nasty situations.

I am more concerned about efficency and weight. The align400L I have has enough power on 3s, I would like to get more head speed out of it but Im afraid the temp will go through the roof if I go higher than a 15T pinion.

I agree with tailrotordave, the video shown proves nothing without a better demo flight. Notice how the heli rotates so severely to the left as the collective is stabbed? He must be pulling a whole lot of positive pitch. The gyro cannot hold the heading.

I have had underpowered helis that appear to have great power if there is enough positive pitch slammed into the collective. Notice the climb outs are rather short. To really prove that there is plenty of power the climbouts would have to be two to three times longer. I believe the headspeed would decay severely if this were done with this heli. My "awsome" weakling helis only looked impressive during the first 50 of climb. After that, they would bog and become rather pathetic. Once I learned about straightline -10 to +10 degree pitch curves with the appropriate throttle curves my takes offs were less dramatic or breath taking, but the overall flight of the helis improved ten fold. I want to see if this heli can stand up to a good 3D flight. I bet it can, but the jury is still out until filmed and posted.

I didn't see any tick tocks, funnels, piro flips, only a bunch of flippitty floppy loopty thingies. It appears as though the heli can't stay inverted, or the pilot cannot maintain an inverted hover. Either way, I am not convinced until I see this combo fly like a properly set up and piloted 3D machine should.

My heli will do rolling tic-tocs no problem. I stiffened my head damping, and am trying tumbling tic-tocs. Power might be a problem there, but I am just learning, and finesse would surely help. I learned to fly on the the early micros, and learned that weight is your enemy. The new power systems can make an overweight heli fly, but it won't flow through a routine, and surely won't auto. I am trying to keep my heli as light as possible, and at the T-Rex's disc area, that means keeping a power system that uses a 1320 pack. I have flown my chopper with a 3 cell 2100 pack, and the throttle response and power in a climbout was better, but I am sure that it would be a pig in high G moves, and auto's would be gnarly..... I disabled my driven tail, and my heli does auto...barely.

I'm trying to get my Razor 2500 working in the TREX,
it's only 43 grams and does have pretty good power,
would be good if I could drop back to a lighter battery pack,
would need a 9T to keep the load and head speed down...

I certainly learnt that the weight is your enemy with the Zoom,
a bigger battery made a huge negative impact on performance..
However many batteries simply can't supply the amps required
to even make the TREX fly - it's that heavy - weight sux...

I'm in the same boat as 3De,
just want the heli usable to chuck around,
not taking it too seriously,
but decent efforts to cut weight off the TREX,
which should be rewarded in flight performance and duration
(if not also avoiding burning out motors and/or batteries)

Wow. Only problem I saw was that the Trex lands really poorly with that motor!

Guys, power isnt an issue if the setup was suggested by Gary Goodrum!

Trust me

Gary is, for the lack of a better word, "obsessed" with getting the ultimate power. He was the one who tried to convince me to run 10s in my Raptor conversion, and 8s in my Logo 10! He is putting together a T-Rex to test 6s lipo pack right now, as if that 4s setup wasn't enough. At 2.3oz, this is one of the lightest motor with the highest efficiency rating. The heaviest we've tested being a Hacker B40-15s which was on my porky Rex.

Everything you guys have said about good indication of power is true. If this setup wasn't as good as it is, Gary wouldn't have posted the video. Granted the heli is not setup optimally yet, but watch for more video coming.

I jumped on the chance of getting one because I know when the word gets out, there will probably be a shortage of these motors.

The 4s 1320's are already gone from TPPacks! I got the combo deal and a spare.

My former post had nothing to do with the video post, I was just asking a general question about how everyone is judging power. I just happened to post the same time as Gary. I am extremely interested in everyones ideas on how to power this heli, but I would like some more feedback besides climbout power. Consistent pitch holding power throughout a move is more inportant to me....
Happy flying to everyone.

Neumotor Website

The Neumotor website doesn't seem to be that up to date. They don't seem to answer emails and have no prices listed!

Does anyone know how much their motors cost and where you can find them (tppacks do not have them)?

Looking for another motor......Mega 16/15/3 is the one I am leaning towards so far.
