| Just wanted to let everyone know that I have been using a Neu 1905 1.5Y 1350KV motor in my T-rex 500 for about 2 weeks now...Although I only have about 20+ flights, it's turning out to be an awesome motor. It's a bit lighter than the Scorpion, but much wider, so a little tweaking needs to happen to install it...I took some pics, but still have to upload them. Basically you have to pull the bottom plastic plate which takes about 30 seconds, then you have to grind out the inside portion of the motor mount where the shaft comes through. The Neu motor has a larger bearing housing, thus the motor mount needs to be opened by 2mm, again not much work. The next step, is either shaving a small amount off the frames where the top portion of the motor hits, or you can do what I have done temporarily and that's to simply stack two motor mounts, lowering the motor so it does not hit the frame...Again, I will try to get some pics soon....Now the good stuff....The motor, sounds much different than the stock and Scorpion motors, it's more turbine-like. I gained 90 rpm worth of headspeed and an additional 200-300 mah flight time. I have done a bunch of Eagletree testing, and the motor pulls the same amps as the Scorpion as far as max and average, but seems to be more efficient, as I am using 200-300 less mah. The power is awesome too, the Neu 19xx series motors are known for their torque, thus this motor does not bog at all. My buddy and I did 5 side by side full pitch climbouts both with the exact same setup, except his had a Scorpion 3026-1210 and mine with the Neu......there was no contest at all, mine blew right past his every single time. I even swear that the heli feels smoother....I even let my buddy fly mine and he agreed that it does have a bit smoother feel to it......This is an awesome motor that I must say is just like the other Neu motors out there....I forgot to mention that I am running this motor on 8S but with the smallest pinion of 12 tooth...The great thing about this motor is that you can run it on 8s or 6s....Running it on 6s will give you much more options as far as pinions go. I must also mention that I have over 150 flights on my Scorpion of which I feel is an awesome motor with tons of power....However you will notice the difference between the two right away....I have also ordered a 1509 2.5Y that should work very well also. This one should work with the Jazz as the 1905 series does not, thus you have to use the Castle or the Align....Once I get the 1509 I will post my findings..... |
