I have never had problems with torque rolling with mine. Granted I don't have a real powerful set up, I'm only pulling about 400 watts but torque rolling has never even been close to a problem.

Between those three motors I'd go with the 28-47-2 or 1.5. I've played with both and on 4s for the 2Y and 5s on the 1.5Y you'll get some awesome speed and vertical.

Keep an eye on your amps, but I've run those set ups on 7x6, 7x5, 6.5x6.5, 6x6 5.25x6.25. Any props around that size will be fine. Test different set ups. I have to say that I favored the 28-47-1.5Y the best and I was able to run that up on 5s as well. You can really push those ARC motors. Good for the price for sure and Dave is a great guy to deal with. I never worried much about my amp draw because I always used an 80amp Castle Creations Phoenix ESC, so, like I said, keep an eye on those amps depending on your battery and ESC. I used Thunder Power 4s and 5s - 3300 V2's.

Agreed, a watt meter is a must for this application. I would start out with a 6x4 and see what that pulls. If you could make it to a 7x5 that would give you more thrust, but I bet the smaller prop and higher R's might give you a bit more speed.

Wingwrecker, That is the point. I am putting a JS-1400 in my A-4 so the 2W-20 came available and with the FJ without a motor it was a no brainer. She is gonna see some air for trimming and such tomorrow. Then she is getting packed up for SuperFly.

To the guy ordering the 28-47-2. If you're getting a 70a suppo controller from lightflight as well, make sure you check. BEcause i ordered one of those at first, and it was for 4-7s only, so you wouldn't be able to run 3s. So you might want to order a different ESC.

And about the 1107-2Y. If you run a 6x5 on 4s you're looking at 114 amps, and on 5s you're looking at 151 amps. So all i have to say about that setup is lol

You might look into something like a 4.75x4.75 on 4s (maybe 5s) or a 6x5 on 3s (76 amps). or something really small on 5s, like a 4.1x4.1 or 4.5x4.1. Lightflightrc sells a 200 amp controller now, but it is HUGE and lets be real, i doubt your motor would be able to handle 80 amps, none-the-less 150. I have been wrong before though...

FlyA123's,

I've been out of town and will return tomorrow. Send me a PM and I will run MOTOCALC for you.

I'm not sure if the resistance values for that motor are published or not.

*** 5 days ago, I got a list which has 90+% of all NEU motor resistances in it. Odds are VERY good that if your motor is one of the ones which does not have its resistance on the web site or in the online simulator that I have you covered.

I should have an answer for you tomorrow night if you remind me.

***Please list your battery specs in a post or PM.

Im using the exact same set-up on my FJ but Im concerned that the Eflight is only rated at 42A peak. Ive heard the Eflight doesn't like to be pushed.
How long have you been pulling 60A out of it ?
I'd like a bit more performance but I don't want to burn my motor out.

This setup is really fast! But it pulls around 60A WOT on a 3S pack...that's a bit too much for me.

Here's my setup:

Motor- ARC 28-47-2
ESC- Align 35A
Prop- APC 6x4 sport
Pack- Zippy-R 4S-2200

Mine is fast too...it's a bit heavier due to the motor and extra cell. But it's a lot easier on the pack. It pulls around 40-45A WOT.
I can fly for 9mins with throttle management.

I'm not running the eflite setup...mine is the ARC. However, the eflite guys here are all running 3S and the combo seems to work fine.
