You can use the 2712-17 1700 kv motor here.

http://www.headsuprc.com/servlet/the...lectric/Detail

You just need to use a 7-3.5 gws prop for 3 cells and a 8-4 prop for 2 cells. I have used them before, shipping is just $2.00 and is fast (they are in america)

You can also use there 10 amp esc and 9 gm servos too.

This is a little more expensive than hobby city but they are faster and are good people to deal with.

The motor mount can be found here about 1/3 of the way down it is labled the "8mm Magic Motor Mount".

Don't use lightflite blue wonder motor because it is too low of kv for use in the stryker.

Good luck and lets see the styker when you finished.

Right now, the auw is 13oz, but not for much longer...I am getting ready to glass it so I can add a Mega 16-15-4 on 4s
what prop are you using?

Hey Steve...
got my stryker airframe in the closet waiting for santa to wrap it. got servo's and motor from headsup ordered and motor mount from the other suggestion ordered also. Now i have a question..... are you just tapeing the motor mount to the airframe and with what tape?? and the elevons look as if they are taped on also... am i seeing it correct?? Hope i can pick your brain so i can get this put together the right way.
thanks

jmccoy I normally glue the motor mount with hot glue. If it is cold where you live, the hot glue seems to not hold as well in the cold and you might use epoxy. Make sure to get the motor mount straight. The same with the fins just a little dab in the front and in the rear in case you need to replace them. I tape the elevons with scotch exteme packing tape (office depot). I have also used clear duck tape (walmart), it looks the same. I just put a piece on the top and none on the bottom. It is probably not the best way but it works for me. I just check the tape before I fly. You have to cut an angle in the bottom on the elevons so they can hinge. If you put on a 8 inch prop you need to trim the rear fin tabs as shown in my bottom pict of the stryker with the lights. Also remember to keep any paint light. I recomend a paint scheme like this.



Yes i know I have a lot of strykers. This one is a 17 ounce 55 mph plane.

Since I am showing all my light stryker I have made. This is my 10 ounce styker powered by a park 250 with 35 watts. Proving you don't need a lot of power to fly these. It was a little under powered and the blue wonder has more range of flight.

I have a ton of EPP foam I got from SloperSteve. I've also picked up some EPP block foam, to cut canopys out of.
The elevons are 6mm depron about 2"s wide for slow flying.
I also built one with the 1300kv, 24g outrunner, 8x6, on 3's and it had unlimited vertical.

Motor Mount


Hey butch..... how did you mount the motor to the frame on your lightweight stryker? And how do you determine the center of gravity to get the plane to balance out??
Thanks guys...

Since the center of lift doesn't change in a Stryker (lightweight or otherwise), the center of gravity remains the same as well.

jmccoy, There are 2 small divots in the middle of the hand grip cutout on the bottom of the plane. This is the center of gravity. You place your finger tip in them to balance the plane.

I used a carbonfiber motor mount and got it mounted to line up with the cord-line of the wing.

I used wider ailerons, which increased the wing area and moved the C/G ballance point back just a bit.

Heres the Thread, it has a pic of the motor mount. Butch
