Any set up you would use for a 3D EPP foamie will do.

I used a stick mounted Ultrafly B/06/10 1000kv outrunner, swinging a GWS HD 8x6 prop with a 15 amp ESC and an 800 mAh 20C battery. There is enough room in the battery bay to go up to 1300 battery which I use sometimes when ridge soaring for ballast.

I want to build mine like yours. I'm new to RC planes so speed is not on my priority list. I just need it to be able to handle 5-10mph wind bc it's always windy in Chicago. But slow enough that I can learn to fly.

If you don't have any Blenderm, you can use plain old packing tape. Tape doesn't like to stick to epp, so you may need to spray a light coat of 3M 90 or 3m 77 spray glue where you will be placing the tape. Let it dry for a while and then the tape will stick.

Hi all,

After reading this thread, I ordered the parts and started building my light Stryker last nite. I'm using the following motor and mount:

- 2712-17 1700KV motor
http://www.headsuprc.com/servlet/the...ner-Brushless-
- Motor mount
http://www.headsuprc.com/servlet/the...ck-with/Detail

I was wondering if I need to angle the mount and/or motor a certain way to counter the torque? Sorry for a newbie question, I'm still learning to fly and this is my first Stryker.

Thanks!
Tom

I used that same plastic stick mount on my lightweight Stryker (though I bought mine from HobbyKing). When I installed the mount, I attempted to align it parallel to the top/bottom centerline of the fuse, NOT to the top surface of the fuse (which angles down toward the back because of the tapering fuse/wing thickness). So the stick mount is embedded a little deeper towards the front. See the attached photo. It worked out just fine that way inflight...there are no sudden pitch-change effects when increasing or decreasing power. There is a build description and another photo of my lightweight Stryker here: http://www.rcgroups.com/forums/showthread.php?t=1337131

With the lightweight setup and the motor you're using I doubt you'll have any torque roll issue. Here is a diagram showing how it works. Might be good to build in a small amount of left thrust per the diagram. One or two degrees is good.

I used the same motor mount. I just glued it to the top surface of the wing. I do not embed it in the wing at all. This gives it a very slight down thrust which I like. It does not pitch up or down with the throttle and helps holds the nose down with full throttle. I align it to the nose as straight as possible with no left or right angle.

Notar's advice would be good if you had some serious gear in your Stryker, but for lightweight, low-powered stuff, don't even worry about it. If your motor was mounted on the front, you may need a slight bit of angle to the motor, but with a pusher, no left thrust is needed unless you are in excess of 600+ watts. My "Outlaw" Stryker at 600 watts and 120+ mph uses no left thrust and has no torque issues at all.

I agree with you murman.......but its good to be aware of the situation to avoid a sloppy build where you accidently end up with a bit of right thrust on a stryker then wonder why it's hard to control....That's why I suggest at least tiny amount of left thrust as a good practice. Not critical as long as you're dead on straight.

Hey wow!

Here is a motor that might be fun on a light stryker. Don's RC has this 2200kv brushless outrunner firewall type mounting......only 29 grams. A little small for what I've been used to. This one has been tested with up to a 6x4 prop which pushes a stryker real good but I'm afraid it would overheat. The 5x5 would probly work better.
