Stryker motors: High performance, low cost Turnigy 28xx comparison
Did some static testing on popular low-cost Styker-motors today, and here is what I found:
Turnigy 2835 / 3900KV Inrunner
Prop Amp Watts Thrust(kg)
TGS 6*4 56,5 609 1,38
MA 6,5*4 73,1 750 1,16
TGS 5*5 53,2 558 0,93
APC 4,75^2 44,7 477 0,72
Turnigy 2836 / 2350 Outrunner
Prop Amp Watts Thrust(kg)
TGS 6*4 32 358 1,14
MA 6,5*4 49,3 526 1,13
TGS 5*5 29,6 331 0,82
TGS 7*4(UoB)60,8 666(Beast?)1,5
Tried the configs with 2 different ESCs an 2 different batterys:
In these setups the TowerPro H40A ($9,98) performs as well as Turnigy Plush 80A........
In the case of LiPos(3S1P), the rather expensive Hyperion VX 2200 (35c) is out-performed by 5-10% by Turnigy 2200 30C......
Please comment, anyone who has an opinion or some thought to share......
After doing some testing I've found this to be a bulletproof lowcost setup:

TowerPro H40A esc. http://hobbyking.com/hobbycity/store...ed_Controller_
Turnigy 3S1P 2200mAh 30C http://hobbyking.com/hobbycity/store...idProduct=9394
APC 6*4e prop
The Stryker will go some 110mph in level flight and I have measured it to some 118mph coming out of a dive.
See this video and specially the passes at 2:15 and 3:22 which gave the figures above:
After several months of trying different Turnigy 28mm setups, my recommendation will be:
PS: Although I have been running this setup with good results others have reported that this setup will BURN YOUR MOTOR. The kv of the Turnigys can vary quite a bit and the conclusion must be that this setup is not recommended. For a long life with the 2836/2350 you must not exceed 6" prop diameter when run on 4S!

APC 6.3*4 Pylon/Combat prop: http://www.canyonhobbies.com/APC-Pro...apclp06340.htm
This setup gives very good thrust and speed and a static of 68Amps/1061Watts.
Here's a video:
Hope you'll enjoy this thread, but do not waste too much flying time on your computer. Go out and fly your Stryker - that's what it's for...

I have a turnigy 28/35 3900kv in my funjet. With a 4.75x4.75 it pulls 38 amps, 420 watts. Motor is rated at 40 amps 3s. Mine comes down cool after 5 minutes of almost all WOT but I suspect it would fry and die pretty quickly on 4s .

The in-runner holds to much heat and will blow up.
I have one that had about 50 flights.
The out-runner has over 100 flights and is not even warm when landing after 9 mins of 130 mph runs!

Anything over a 4.75x4.75 is way too much for the 2835-3900. I've read Doc's results from the outrunner, and it really seems to be the better choice. So much so that I'm thinking about going that route.

On the 2835-3900KV in-runner a 4.3X 4.1.
On a 4S setup!

am I doing this correct? I used the prop calculator chart and if using a 5x5 prop you need a higher KV motor eg a 5x5 on a 3900kv motor on 4s is showing a pitch speed of 164mph or something stupid fast with decent thrust.
But say using a 3200kv motor and a 6x5.5 prop your top speed is reduced to 135mph on 4s but has about 30 more oz of thrust.
in the end what are you better off doing to have a fast stryker? the 5x5,3900,4s? or the 6x5.5,300kv,4s or something among those lines?

I have used the Turnigy 2835 3900kv motor more than any other hobby city motor. On a Stryker, that motor shines on an APC 5x3 prop.
I would never try this motor on 4S, it will smoke before it even gets in the air.
As for the 2836 2350kv, I just bought one and haven't tried it yet. I hear 4S is possible with a 5.5x4.5 prop. I will be testing this motors capabilities soon.
This is my favorite HC motor thus far. I use it on my combat stryker

Jhonny, use a 4.1 X 4.1 on 4S it will work for many flights!
You would be much happier with a 2836 3200 KV out-runner anyway!
More punch for the money!
I have gotten 900 watts out of one. If you put it with the rotating end at the back of the plane you won't have problem with magnets ungluing from the heat!
|Mar 20, 2010, 02:30 PM|
You will have the the bolts facing the nose cone.
push the shaft out toward the rotating end! The prop will be farther away from the fuselage.

These motors I have tested and ran the crap out of them.
I have used the a 6 X 5.5 - 4.1 X 4.1 APC and gruapner props on them!
I have ran 3S, 4S and 5S setup with them!
I can tell you this the lower KV ones are fun when people at the field, say stuff like mine is faster than that!
I just laugh and change batteries.
I prop these for 3S and they draw lost of amps and stay cool.
I don't like beating the holy hell out of my batteries.
I try to find the setup that gives me plenty of power yet allows me to run my sTuff for every
650 watts on a 4S.
800 watts 4S
1100 watts 5S

It appears I will need to replace my Stryker C motor soon. Can you recommend a Turnigy or comparable motor to replace the stock 1880 kv one. I Plan on using these components: Stock prop and stock prop adapter , 2200 3S lipo and 30amp esc. Something that will easily mount to the stock motor mount with no/minimal modification would be great

doc how are you getting 1100 watts on that motor? On 4s with a 6x5.5 I am getting like 650 on the calc.
what prop and motor do you recomend for 4s 2200mah packs with a 50 amp esc
|Mar 20, 2010, 08:06 PM|
This motor has excellent thrust on a 6x4 apc sport. I think it outperforms the 2835 2700kv.
