I see readyheli has a new upgrade motor listed, the H 18/11H 1000w 1100kv for $69. does anyone know whos motor this is and will it run with the 50 amp esc? any ideas on performance?
thanks

fyi: it is from a factory in taiwan called RCP. they have been making private label motors for several companies for quite some time, including all of gauis motors. this is the redesigned can and anodized finish. the h/18 is excellent on stock setup using smaller packs, such as 2100-2200 mah packs. the h/24 1500 watt motor is for hard 3d and i put its performance next to a z30 or century, ;-)

hth.

thats what I assumed, have you done any testing on this for performance comparisons over the stock Gaui 850kv motor, Is it a step up from the stock motor and a step down to the gaui 1500 motor? maybe similiar to the Z20?
thanks

stock is actually 890kv, but this can design is fan cooled, and actually has more torque...i would say its perfect for those looking to use smaller packs and perform loops, flips, and rolls.

4 point tocs, funnels, 'canes, you need to look at a much larger pack (2500-4250) and a 1500+ watt powerplant.

Hey John,

So this would be a perfect mid-size motor for the Gaui? and will it run efficiently using the 50-amp bec?

yea, sounds promising doesn't it! maybe he would like to send me one to test!!!!

thanks again for the info!

Well bummer, looks like they are already out of stock on the motor! i did order my CNC grips but guess I will have to wait on the motor. Hopefully someone here picked one up so we canget sme reviews next week on it.

I for instance have the silver bullet 1500W engine. And of curse it used a lot of power. The flight times were at 4min tops with 3200 packs and they were cocking at 50°C min. But i reduced the Head speed by dropping the throttle curve.
Does anybody know if there could be a problem by running a powerful motor like the 1500Watt with reduced power? I am only into normal flighing and hovering.

Careful with the new 1000W motor.
I "maidened" this motor today with a 14-tooth pinion, on 5S/3300mah and original 50amp gaui ESC,
flight went fine for 5 minutes,
Higher headspeed felt so nice compared to 850kv stockmotor with 15-tooth pinion.

Then came the 6S test: I assumed I could use the same Trex450 Batteries, I set the timer to
4 minutes just to be safe, and also connected the Whattmeter so I could have some solid
numbers. Heli felt Wonderful! I did a few loops, FFF, then after 3 1/2 minutes it started to feel weak.
I landed the bird and removed the canopy to see what the meter was showing.

One of my 3S packs was puffed! Meter read 64Amps peak. Battery went back to normal
size after cooldown, but Cell#1 is at solid 3.3V, the others are at 3.4V.

So for those of you wanting to step out of stock 850KV to this new 1100kv, tread carefully
I don't believe you are meant to use your old Trex packs with this new motor, or your old ESC.


Good luck,
Frank...

I just installed that exact motor..I am using FP 2170 Evo 25 packs. Have not got a chance to test it yet.

Were you using stock 42 and 61 gears ? Also were you using CNC blade grips and CF blades ?

Thanks

Yes, all stock gearing was used for this test (42/61)
Metal head/grips, Original woddies (haven't crashed yet, knock on blade)

Calculated headspeeds would be as follows (per readyheli's headspeed calculator)

Before: 850kv (stock motor) 61Tmain/15Tpinion 6s = 1373rpm 95% eff.
After : 1100kv (H/18/11/H) 61Tmain/14Tpinion 5s = 1382rpm 95% eff.
1100kv (H/18/11/H) 61Tmain/14Tpinion 6s = 1658rpm 95% eff.

Idle-up Throttle curve is: 90-85-80-85-100

Gearing mesh was good, not tight, just a bit of backlash at the highest point.

It's possible the spec was "conservative"?
Maybe an error in labeling? The motor can is the same dimension in width/height as 850kv. I've seen the 1500w motor, it's taller.

but according to the measurement,
64 peak amps, 1360 peak watts surely puts this motor closer to the 1500W category.

Although I loved the handling, I'm not ready to buy new batteries as I enjoy flying both
my Hurricane and Trex 450 using the same type of batteries.
Good news, battery wasn't ruined, but I'll be going back to stock motor until I feel I must have more power, but my skills are not there yet.

Another caution I must add, the tail pitch slider uses pushpins, one of them slid out during
piro's, luckily I landed safely, now I've got a 2mm screw/nut with locktite keeping them attached. Always check that tail prior to takeoff, or CA those pins in place.

what packs were you using? What kid of flying were you doing which led up to the 64amps, and have you done the same tests on the stock motor?
and are you going to keep the motor or do you want to get rid of it?
