XLR-3 Stretch X Racer

XLR-3 is a 3" stretch X racing frame. This little frame is designed to follow in the footsteps of its bigger brother XLR-4. Although similar in appearance, XLR-3 is completely re-designed to make it a 3" platform, starting with a durable 3mm main carbon plate. XLR-3 is also designed to accomodate standard flight control boards as well as the venerable HS1177 standard CCD cam. This creates a very competitive package that performs just as well as it's bigger brothers, just like SCX-140, but with the forward flight stability stretch X designs are known for.

How durable is it?

No frame is completely unbreakable, but XLR-3 has no problem playing with the big boys. It can hang with the competition and take a beating. It's like that little brother that gets pushed around by his older siblings, but persistantly keeps coming back for more.

Build it to be yours!

Using readily available, common 20mm long M3 standoffs, you can easily customize the look of XLR-3 to make it standout. Below are photos of my XLR-3 prototype which I built with XNova 1407's and matching red standoffs! 

Stock Kit Pictures:

The stock kit isn't without color though: kit includes Space Cowboy's "Orion Orange" 20mm standoffs as standard issue. Color wise these pair extremely well with T-Motor F20's, which are also an excellent motor choice for this 3" racer.
