  • Figure 17 Starting with the lower bearing lock install (2) M3 Nuts with the parallel sides of the nut  aligned to slide into the grove so that you have nuts installed similar to Figure 18 Note Grooves for nuts may or may not have a snug fit
  • Figure 19 Install lower bearing block with captive plate facing towards what would be the ground or landing skids assemble using (2) original OEM bearing block screws using Blue thread lock and tighten snug NOTE DO NOT OVER TIGHTEN These bearing block assemblies are a positive lock design by Rotorworkz they do not move or shift once screws are drawn in. Positive lock parts may have a soft or tight fit this is due to + or - .012” inch variation in G-10 thickness this is Manufactures tolerances not Rotorworkz so please pay close attention when first time installation of being block in Frame panels
  • Figure 20 Install remaining bearing block assemblies Repeat the above steps for middle and top bearing blocks Note All Bearing blocks should be installed with captive plates facing down towards landing skids.
  • Figure 21 Note the shape of the Anti rotation Guide and how it is installed into frame Figure 21A the thinner side of the guide slot will face towards the left frame side panel use OEM bearing block hardware to install guide
  • Figure 22 Shows installed M3 x 8mm Button head screws this allows for better clearances

Special note do not add thread lock on forward bearing block screw as later in assembly you will remove it to install a frame doubler this method is only used to seat the bearing block fully into the frame panel Figure 23

Your “S” Shaped plates should be oriented in the same position as in figure 34A this step is import so you will assemble a right and left Bridge plate

Power up your servos using you radio system remove any sub trim or mixing that may be preprogramed. Now set radio throttle/pitch to center stick your 3 cyclic servos should now be centered.

  • Install factory round servo wheels rotate wheels by removing an reinstalling to achieve the best 90 deg hole positions.
  • Using (3)M2 x 6mm screws and (3) M2 Flat washer install Subzero arms on to factory servo wheels note: wheels have 3 holes per 90 degree position you will install screws into the same hole for all three positions on the Subzero arm plate to allow for full adjustable travel
  • Figure 33 shows installing a 1/16” (1.5mm) Rod through both 90 Deg reference holes located in frame panels figure 36 shows location of this hole marked with a  red dot.
  • Push your 1/16 (1.5mm) rod through the frame and through the subzero arm linkage ball mounting hole while you servo is still centered via your radio system. Now tighten all three screws enough to keep servo arm from shifting or moving. remove arm assembly and repeat for opposite side.
  • Figure 34 shows a small adjustable square and scrap piece of thin flat material in my case I used a scrap piece of 1.65mm Carbon Fiber this will be used to take a reference measurement of either pitch or aileron servo arms to set you elevator arm.
  • Figure 35 shows setting scrap material on top of the frame using a adjustable square set the blade of the square on top of a centered servo arm noting the position you rested the blade on and took measurement. Now lock blade in position use this reference
  • Using the preset square set your elevator servo and tight screws. Figure 36 Now.
  • Remove one servo arm at a time and install M2 Nuts using blue tread lock and tighten. Verify again that all 3 arms are still at there reference position adjust arms if needed.
