After about 40 minutes I had the lights, interior cockpit and seats complete. Let the unit sit for a while so the epoxy sets up, next we will begin the frame and tail assembly. I can't believe how quick this model comes together. |

Up next is what I believe to be one of the most important and crucial parts of a good flying Heli. Its important the tail slider is BUTTER SMOOTH. Trust me the extra time we spend now on it will be worth it later on. The first step before we start is to remove the control arm that attaches to the yoke, BE SURE not to lose the small brass washer. If you look closely at this brass washer it has a lip on one side, pay close attention to how it comes out. The small lip should make contact with the inner race of the bearing so when you tighten the screw it doesn't cause binding. Next you will have to remove the small arms attaching control yoke to tail grips, you must remove the INNER ones before being able to remove the OUTTER ones. Before we begin its important we understand where almost ALL Helis experience binging here. The small arm is made out of plastic and it has a brass insert, the binding can be in two places. One of the places is the fit of the brass spacer within the hole of the plastic arms, using a drill and turning it BY HAND not a drill will ensure a good fit. Make sure you go easy on this step because once you make hole too big its a little hard to go back. The number two place where binding is caused is in the total width of the plastic arm and the total width of the brass tube, if the width of the plastic arm is thicker than the brass tube then when you go to tighten the screws it will bind. we want to be able to tighten the screw and it to compress on the brass tube NOT the plastic arm. To achieve this you will need to LIGHTLY sand the plastic arm, this will take trial and error but take it slow. IMPORTANT ----> now that we spent all that time making the tail butter smooth we dont want to ruin it by adding loctite to the screw then inserting it in, sign this will cause loctite to ooz out and get not only on the plastic arm but also on the brass tube. I RECOMMEND you use a small pin and apply loctite to the pin then from the REAR insert the loctite into the threads. NOTICE when moving the tail you may notice a little resistance even after all this, this is because the screw that holds the tail grips to the shaft itself is applying some pressure but dont worry as the blades spin they will release this pressure. You can try this by pulling on both grips while moving the tail in either direction.Lastly lets test fit the small tail section of the boom and torque tube, this small section dent require a bearing support. Remember to add the support rod for the pushrod and notice the notch on the boom.                |
