lightweight stryker, how light can you go?

I know most people tend to go heavy and fast with the stryker, but this plane is very fun to go slow and light weight. I have built several of these planes in the 10-16 ounce weight and fly them a lot more than my stock stryker. These lightweight strykers can go from a fast walk to 40-50 mph and fly from in a gym to in 20 mph winds. They are also cheap to build. I can build one of these minus receiver and battery for under 50$. I am using a blue wonder 1500 KW with a 8x4 prop. 9 gram servos and a thunder power 730 battery. So come to the light side and have fun.





Here are some videos.

Wow - you've turned it into a pussy-cat. Nice to see it on the other end of the power-curve for a change.

It might be a contender for the ultimate elevon-trainer (and low-cost, too)!

I built one years back, before the BlueWonder with a Esskay 400, 2 cell at 9.1ozs.
With a BlueWonder maybe one could even go under 9ozs!!

Did you do anything to lighten the airframe? Or, is the weight reduction from the equipment only? Very nice, I like this one.

I bought the bare airframe and did not modify it much. the bare airframe weighs approx 5 ounces. I did use blue fan fold foam for the fins and elevons that were then covered in black microlite film. I used thin cardboard that was colored with a black sharpie and covered in clear tape for the battery covering and is secured with velcro. My total body with fins and battery hatch weighed approx 6.5 ounces. The paint is a very light coat and weighed .2 ounces. The motor mount weighed 4 grams. The stock fins and elevons, motor mount and hatch covers weigh approx 5 ounces for a total frame weight of 10-11 ounces so I saved approx 4 ounces on the complete frame. I also use a 24 gram motor, 9 ounce servos, and an under 2 ounce battery. I also get unlimited vertical with a fresh battery and a top speed of around 40 mph for this one. Here is another similar one I made with lights for night flying. The lights added a little over an ounce.

Here is my lightweight Stryker. I cut the fuselage completely off and clipped 2" off the ends of the wings also. Wingspan is now 30" and with the Wicked Jr motor and 1200mAh 3s lipo, it will do 70+mph and fly slow also. Cut the throttle, and this thing glides forever!! 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

How do you get the home made vertical stabilizers to hold in the airframe? Is there a slot they slide into? Im thinking about building one of these cheap slow flying strykers. There is a guy at my field with on who loves his.

On this lite build, I used EPP for the canopy and fins with a C/F stiffener and 6mm depron for the elevons.
Also the elevons were widened to get better low speed control.
I built several and made up some kits.( I still have a couple)

Some of the local beginners built them and had no problems flying them since they were able to go so slow.
We used the 1300Kv, 24g, BlueWonder/8x6, Berg rx, and 2 Pico or HXT-500/900 servos.
It ended up being a real cheap build. Butch
