ORIGINAL: Magic Hook
I may have caused my own trouble by trying to upgrade. My V2, and 500 builds just fell together with the finless vids and flew off the table without a single adjustment.
It started with the head assembly I decided to get metal main blade grips because I felt they were safer. Could not get rid of about a 1/16 of end play so I put the plastic back on. I dont know, maybe they are for a 600n but they dont say that but its a wasted 50 bucks. I am trying to find out if its okay to shim them. Next I had purchased metal control arms and what was listed as a upgrade metal washout base. The washout base that came in the kit was one piece aluminum, the "upgrade" was metal with a brass sleeve inside. When assembled its just a bit sticky. I hate that. I plan to put the origional base back in it but I moved on.
Yes, I spent a lot of time getting the frame square working off glass, The frame, bearings, and all of that went well everything fit nicely and ended up square with the world. But I had purchased metal bell cranks and control leavers. Those would bind without a additional washer between the horn and the bearing in the frame. I took that apart 20 times. Its a really paper thin washer.
The torque tube was another upgrade I wanted to try. It went together well with one exception. the pitch slider needed a sleeve changed. After I put that on, the pitch slider became sticky. I have not tried to pollish the shaft but I did order a metal pitch slider upgrade. LOL
My biggest trouble has been the servo installation and setup. I was not able to just copy Finless because I got Futaba S9452 cyclic servos in my combo. Choosing a servo horn has been a challange. I had ordered the Align round ones. Really they are designed for the ball to be on only one side. On the Ail and Pit servos I could NOT get anything close to the right alignment for linkage to the bell cranks with one spacer. If I removed the spacer it got close but the servos bind together in the middle. I now have two spacer and the balls on the inside, its not bad, but not exactly parralle with the frame. I just ordered a set of CF horns and hope they work better. On the Elevator servo the ball needs to be on backwards with the servo install per plan. That put the ball back in the recess made for the nut. I dont like that, and its still not EXCACTLY straight, I have to loose the set screw and move the control leave just a touch of the edge of the slot in the shaft made for it. I am at a point now to just take the three metal leavers off the darn thing and go plastic. I went with them because I prefer the balls in metal rather than plastic.
ANY suggestions would be GREATLY appreciated. Thanks for asking!
