Hi All,

I noticed recently on the Turbulence brochure (See MRC website), the Gyro is actually mounted up behind the cyclic servos, just before the hex starting piece. Is there a special mount to mount the gyro there? I know one of Dominik's recommendations it to not use the front radio tray (the heavy extended plastic bit), add another mounting plate under the front stub and mount the gyro inverted there.

My Gyro is currently in the stock location, but if I can get it to the place behind the cyclic servos, i'll move it there (it's close to the main shaft, and out of the exhaust oil).

As I recall that picture is one of the production prototypes for the D3 back in 2008. The rear metal bottom plate for the skids and tail boom mount that's in the final production model is not present. In that picture it's using the same front bottom plate for the rear. Don't worry, you don't have bad eyes. I caught that one too back in 08 when I was checking out Hirobo's website for the early Turbulence D3 online brochure. I didn't like that configuration since the skids are too close to each-other and seems like it won't sit properly should Hirobo kept the design that way. It's good that it didn't turn out like that or else I wouldn't have bought one.

I still can't figure out how or what they have mounted the gyro on though? looks like it could be a good location but I can't see how to mount it there on my D3

Yes the photo you are looking at is of a prototype.

Hi Greg,

How did they mount the Gyro there on the prototype? was there more room in that area? I know one of Dominik's suggestions is to mount an extra gyro mounting plate inverted on the stub nose configuration (no rc tray extension) and mount the gyro there inverted to get it away from the oil, but the mounting option in the pic also looks like it could be good too.

Brendan,

Just looking at my D3, there are a couple of holes you put a mounting bracket across but it would block the starting hex. There's a hole alot through the ervo mounting bracket you may be able to something with but you then run into clearence problems with the canopy.

I'm guessing with the prototype, they were using a Freya canopy at first which has more room in that area. I use the standard position behind the main shaft with no problems.

Bugcatcher,

I use the same stock position too and came to the same conclusion you have as well (the holes are there but would block the hex starter, and that hoel in the cyclic rail doesn't appear to be for anything). I'm going to be running the carbon frames on my second D3 so i'll try the inverted position up the front under the stub nose to avoid oil.
