Summary of Contents for Precision Aerobatics XR52

  • 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-52 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

    Note: There are two identical sets of servo openings on each side of the fuselage. Choose the side per your preference. Elevator servo should be mounted on one side of the fuselage (upper opening) while the rudder www.PrecisionAerobatics.com Copyrights ©2014 Precision Aerobatics. All rights reserved...

  • Page 5 Locate the plastic ball link and install it onto the CF servo arm with the ball on the bottom side of the servo arm. Install the aileron ball link in the servo arm inner mounting hole. The order of assembly is M2x8mm bolt/ball link/CF arm/nut. Apply permanent Loctite to secure the nut. www.PrecisionAerobatics.com Copyrights ©2014 Precision Aerobatics. All rights reserved...

Verify with a ruler that the CF stringers do NOT protrude the rear of the motor box, otherwise the motor box will be mounted with an incorrect thrust angle which will impair the XR52 flight performance, therefore, if needed, sand/file the rear ends of the stringers flush with the motorbox ply.

  • Page 13: Motor And Esc Installation

    Make sure your X mount bolts are at least 14mm long. Due to the thick Install laminated XR52 mounting plate, shorter bolts may strip the thread and air baffles cause the motor box to fail under the extreme thrust. We strongly advice to use temporary (blue color) Loctite on all mounting bolts.

    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 171717 Copyrights ©2014 Precision Aerobatics.

    # AC-2210). CG of 107.5-108.5mm is more for sport/IMAC flying or in windy condition. NOTE - The XR-52 is an excellent high speed precision aerobatics and slow 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.
