Neu 1910/1Y vs. 1512/2Y/F - 8s Trex 600

Trex600 - Rotorworkz
Flightpower 8s 3700
Kontronik Jazz 55-10-32
Futaba 9451 120 CCPM
DX7
600mm V-Blades +-13
RTF 7lbs 2oz.
Ambient temps were 76F during tests.

VIDEO: 1910/1Y

The same pack was used for each flight. Both motors were tested on the stock 170T gear.

1910/1Y - 13T - 82% = 2200+-

1512/2y/F - 10T - 78% = 2200+-

The 1512 felt like it was delivering just a bit more power. That power was at a price. If you look at the graphs closely you will see the voltage on the pack dropped much lower on the 1512 than the 1910. I believe this is due to the high temps and rise in resistance.


The 1910 gives you great power, its price is lower than the 1512. I see NO reason NOT to run this motor at this time. We have about 70-80 flights on it between Kong and myself, its running in the 130F's to 160F's.

The 1512 has more power to offer, you definitely do not want to stay on the power as long and hard as we did today. I believe we pushed this motor to its limits. 200F after the flight. I have been seeing numbers in the 180F's flying it The 1512 was harder to bog, you could definitely hear the difference.

The new case design being worked on should help with cooling on both the 19xx and the 15xx series.

Oh, and the Jazz, its still going after those 107A spikes.

I see no real surprises here. Both are great motors.

I just wish Steve would design it so the 19xx could be mounted from the rear for tractor use.

It was Bush! I really enjoy low flying videos over hard surfaces, when the dust blows it shows how low they get. Very cool indeed!

Gavin Rossdale. and now I'm going to stab my eyes out for knowing that.

Anyways, that was some killer flying... I especially like the deck slaps, when the vortex of dust gets kicked up... Nice...

Nice flying! The puffs of dust when you get close to the ground are nice

I run the 1910/1Y in my Logo 10 and the performance is ballistic (AUW 2.3kg) I'm surprised it performs as well as it does on that video with such a heavy machine to drag around. Wouldn't a 1912 be a more appropriate size?

And add more weight to the 7lbs 2 oz we have already ? With 9650's its 6lbs 14oz. I think the 1910 pulls it around just fine. I agree a 1912 would be happier, but I'm trying to keep it as light as possible.

Sorry for pulling out an old thread, but do you still run these motors on 8s and whether you still like them? Do you experience gear stripping at 8s? I'm looking to upgrade my Trex-600ESP from 6s to 8s and looking for the right motor for this.

Thanks.

Don't mean to crash the thread, but I've read the Scorpion 4025-800 is a good match for 8s. I have the 1100 kv version and thinking about adding two more cells and gearing down.
