Things went pretty good today on first testing. Not great, but pretty good. It started right up and ran pretty smooth. I watched the video that Raja made on how to start his Spektra and it worked perfect. 2 pulls with the choke on after priming then started the nexrt pull with the chock off. I got the throttle linkage and sub trim adjusted so it would idle smoothly on it's own. I tried spooling up and the RPM would clib to a certain level then drop. If I held it at just below mid stick, the motor would surge up and down. I shut it down and inhibited the governor to make sure I wasn't getting any interaction from that (not being set up yet)but it did the same thing. If I went up slow with the throttle it would climb up then level out. If I advanced the throttle quickly, the motor would quit Each time it would fire right back up with single pull. If it was a nitro motor I would say it was pretty rich on the bottom. I didn't have the manual with me and not being familiar with the gas motors and carb adjustments,I didn't want to adjust it out in left field so I packed it up . I'll read up on the carb adjustments and give it another go.Seeing it starts up fairly easy, I would think it's pretty close.
One thing that I did run into was the tail acting weird. When I got it spooled up pretty good and the heli started o get light on the skids, it jumped pretty good to the right. Back on the bench I noticed when I move the rudder back and forth the whole tail shaft would move. When I took it all apart I notice the set screws for the beveled gear had come loose on the tail shaft allowing it to slide back and forth. I got it all cleaned up and set the lash on the gears, put some lock-tite on the set screws and tightened them up. I have a JR 500T for a Gyro on it that isn't set up quit right yet. I need to adjust the limit on it but can't seem to find anything to adjust the small trim pot on it.
Pretty good day for the first test out with it. Being brand new to the world of gassers, I'm going to like this.
