  • Page 1 Do not stand in line with, or in front of a spinning propeller and never touch it with any object. Precision Aerobatics quality control team checks each plane before it leaves the factory to ensure that each kit is in fine condition.
  • Page 2: Equipment Selection

    Equipment selection At Precision Aerobatics we have gone to great lengths developing the XR-61 in order to provide you with an aircraft like no other. We have used many unique production techniques including our revolutionary PA FiberFusion® to create the lightest, strongest aircraft possible.
  • Page 3: Pre-Assembly

    Avoid keeping the hatch off the fuselage for long periods of time as it may develop some warp due to its length and climate changes. Do not leave hatch/canopy out in the sun as it may warp as well. www.PrecisionAerobatics.com Copyrights ©2015 Precision Aerobatics. All rights reserved...
  • Page 4: Aileron Servo Installation

    If wings are removed often for transportation you may want to consider making two short extension leads that are permanently plugged to the RX and dangle out of the fuselage. In this case the existing servo leads do not require any modification. www.PrecisionAerobatics.com Copyrights ©2015 Precision Aerobatics. All rights reserved...

  • Page 13 Do not force the motor box into the bulkhead slots. If it is too tight use a fine file to slightly enlarge the slots until a perfect fit is achieved.

    Incorrect thrust angle will impair the XR61 flight performance, therefore, if needed, use a 5/16" (8mm) drill bit to slightly enlarge the pre-drilled angle. Test fit during the process. www.PrecisionAerobatics.com 151515 Copyrights ©2015 Precision Aerobatics. All rights reserved...

    Fold the covering over the edge of the bulkhead and use the covering iron to tack it down. Gently pull the covering at the rear of the bay taut and proceed to tack it down. Once satisfied, seal the edges and carefully shrink the remaining wrinkles. www.PrecisionAerobatics.com 191919 Copyrights ©2015 Precision Aerobatics. All rights reserved...

    Tip: It is easier to fit the cowl first with the hatch off as it allows you to push the upper cowl surface over the front bulkhead. Then fit the hatch under the cowl overlap, adjust and continue the procedure of final installation of the cowl. www.PrecisionAerobatics.com 202020 Copyrights ©2015 Precision Aerobatics.

    126mm is more for sport/IMAC flying or in windy condition. NOTE - The XR-61 is an excellent high speed precision aerobatics and 3D performer; therefore, in order to achieve the best of both worlds we spent many hours testing the CG to find the “sweet spot” that offers a peak in overall performance.
