Lets forget about the readings you are getting from the wattmeter for a few minutes......
Is it a Phoenix 60 ?
Did it emit any beeps immediately after shutdown ?
Can you do it again and count them to be sure ??
It should repeat the series of beeps after a short silence (no more than 20 seconds) then, if you could please post the beep/flash count, that would be greatly helpfull here.

Looks like the kv of my Medusa 28-56-2800 is more like 3150 under 3s voltage. Sounds pretty close to what I was expecting, so its time to have some fun with it!

Thekid3418,

That motor is a fantastic 3S motor in a Stryker.

If V2 then Sweeeeeet.

If original version, then it needs cooling vent holes drilled on both ends, OR you better keep to 1100W for short duration.
That power level is what my friend ran, but later burned the motor when over propped on 4S.

1100W is not set in stone; it is just what my wattmeter showed during his maiden. This was roughly double his last motor and he was shocked.

If looking for a 4S motor, you can buy better suited motors for a Stryker due to its high KV (even if V2).

Are ARC motors available outside the US? Get hit by customs AND excessive charges from PO when stuff comes from USA, which sours the deal.

It is V2, and it'll really only be doing stryker duty to annoy people with the rediculously high RPM It actually has a GB on it currently. Its sort of strange to see a 28mm motor with a 16x10 prop on it as I was testing earlier .

I can't wait to finish my new stryker, it's been 2 months since I lawn darted my last one.

The stryker has got to be one of the best things for the hobby in the past 5years, so much fun.

Hopefully santa will bring me a Mega 16-25-2 to try out in my new one.

I tried finding the answer to my question but no success.

has anyone tried a park 400 type out runner on the stryker. if so how did you mount it.where did you get mount and what prop did you use.

also how many amps did it draw..im trying to use a 4s A123(1100 mAh) which is roughly a 3s lipo equevelant pack when under load, in the stryker. these cells will sustain a 20c discharge so I was wondering if a cut down prop will work with this type of batt limitation

INCARUS,

Most outrunners require a motor mount other than a stock Stryker C mount.

The most common successful ways to do it are:

Angle bracket mount
The motor mount area of the plane's body will need to be modified with reinforcement in the form of a plywood plate or fiberglass to distribute the pressure of the mount. You'll also need to reinforce the bottom of the plane since you'll be running bolts through it.
Here's a homemade one I'm running on my Stryker.
You can also use a stick mount, also listed on the first link above. It mounts to a 10mm square stick that you bury/glue to the rear part of the fuselage.

Another method that works if your motor has the prop shaft on the opposite end as the mounting holes is to simply mount it to the rear side of the Stryker's motor mount. This moves the CG aft, so you'll have to compensate for that by moving batteries forward or using a heavier battery, but it also moves the prop back from the body, resulting in better prop efficiency.

BTW, 1100mah will only be OK if you plan on running a very lightweight, efficient, slow flying setup. What 400 size outrunner are you planning on using? Some great fun flyers have run on low kv motors (guessing 1200-1600kv) and slow flyer props.
