HiTec HS 5125 MG slim wing digital servo

Ok I got one of those and decided to try it on the tail of my fully upgraded ECO 8. So far I have three flights with it but no aerobatics yet. I am still trimming out the heli after the crash. I am pretty impress with the servo. At first I set it up pretty much like how I would have done the HS 81. The tail stay pretty solid after I dial down the gain but the response was way too fast for my liking. I was doing pirouette both ways and they were blinding fast. I took it up for some slow forward flight and I was doing unintentional pirouette at every turn. So I brought her down and changed the linkage around. I moved the ball link to the second hole on the servo arm instead of the outside hole. I also moved the ball link to the outside hole on the tail bell crank. I played with the gyro gain a little and I dialed the gain all the way down to around 30%. Now the tail stays super locked in and the response is a bit more sedate.

Here is a picture on how I mount it.

Seismic, I spotted a non upgraded part!!!!!!
How can you live with that?

I can't. So after I finish setting up the crasher I will work on ungrading the transmission shaft holder and landing gear. [img]/ubbthreads/images/graemlins/grin.gif[/img]

Oh dear, oh dear, Seismic my man, there is still a part that is not mentioned and that can be upgraded if you build it yourself. [img]/ubbthreads/images/graemlins/grin.gif[/img]

Besides, the landing gear is not in the picture. [img]/ubbthreads/images/graemlins/tongue.gif[/img]

I don't see that part [img]/ubbthreads/images/graemlins/confused.gif[/img]

Keep looking man, it is in the picture? [img]/ubbthreads/images/graemlins/tongue.gif[/img]

Hmmm.....may be you need to make that into a game. [img]/ubbthreads/images/graemlins/grin.gif[/img] The only other part visible in that picture will be my radio plate. I did upgrade it by trimming the "hooks" off and mounting it to the frame via two carbon rods. I can make a carbon plate and create a mount but I was lazy and it was only a flat plate.

How can you stand that bit of plastic on your heli??? [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]

Seismic how do you like the ali boom clamps?I thought about them but knowing how brittle the cf boom is I figures the plastic ones might be a little more flexable.

>>how do you like the ali boom clamps?<<

I actually like the ali boom clamp better than the plastic one. This is the last upgrade I bought because I was thinking more like you. However I found that the ali boom clamp has a larger "foot print" so the pressure on the boom is less.
