A plane to satisfy your need for speed. Formerly known as the Knief.
The X-ray Racer is a 1 meter, composite pylon racer that's sure to turn heads at your local flying field. Using lightweight, yet super strong carbon fiber in its construction, the X-ray Racer can slice through the air at blistering speeds. It's a simple build with it's low part count and should be easy for the experienced R/C pilot, but there is some filing and sanding to be done for the wing and horizontal stabilizer to fit properly.
Our light, 3s setup gave us outstanding results and resulted in a fast, yet tame, almost docile airplane that refused to show any bad tendencies. Our 4s setup reached in excess of 200mph. The fuselage has plenty of room for a variety of motors and batteries and the wing is held on using a pair of bolts, which are screwed into nuts housed inside the composite layup.
See the build thread HERE for more detail.

The suggested motor can be a beast in this plane. If this is your first plane of this style, I would suggest that you start with a much lighter motor and battery. The suggested Typhoon EDF 2W-23 on a 3S battery utilizing the APC 5.5x6.5 prop should push you up to around 100mph and probably more while drawing around 50-60 amps. Once you are happy with the planes configuration, you can go to a 5S or even 6S battery and adjust the prop size down to keep within the systems limitations and you will see a big speed boost. But be careful not to let the magic smoke out!
You can save a good bit of weight and still have a ton of fun with the Typhoon EDF 3W motor, a 3S battery, and the APC 5.25x6.25EC Carbon Electric prop in this airframe. This will draw about 45 amps typically.
Another great setup one of our guys runs is a TP Power 2930 9D (3300kv) on 4s, which pushes 200 MPH with a Super S Carbon Speed 4.7x4.7. (65A, 1.1kW+) He has also run a slightly more tame Super S Carbon Speed 4.7x4. (60A 860W)
CG is 42-47mm back from the leading edge.
Sorry - photos are out of date - Please see our listing for the X-ray glider to see the current paint scheme. Hopefully we will get new photos up here soon!
NEW Option - FLAPS: If you have a smaller landing area, flaps may be just what you need. Typically not used on a pylon racer, we added flaps for our glider version and thought some pylon folks might have a small field like us and really appreciate being able to land in smaller places without all of the stress.
All airframes are now carbon versions. If you would like a lighter weight glass model, please send us an email request. Thanks!
