Meet Bheka,
2 PG-03 gyros, shoulder extensions to accomodate gyros, head contains a Hitec HS-81 servo wrapped in layers of Lexan and aluminum.

A big Thank You all that have made such a goldmine of information available.

Like the head how did you make it. It looks like you have sandwich the al and the perspect and then cut it out. is this so if it is did you glue it or did you bolt it together.

Nice . Like the extensions on the shoulders to cover the gyros thats a brilliant idea. Also love the blue colour on the black - looks very cool.

Cool head too, massively better than the stock one

Thanks for the comments.

The base of the head is milled out of .25 al to attach to the servo and cover the servo bottom. The rest is layers of polycarbonate and Al. They are milled to slide down over the servo and have 2 long 4-40 screws into the base. The nub on top is a piece of plastic to break up the flat surface.

For the shoulders, I removed the plastic between the front and back. Milled out the top shoulder plate to accept the gyros. Then I removed the servo pins from the gyros and soldered the extension wire directly to the ckt. board. Cleaned up the exterior of the gyro cases, and mounted the whole thing to the top of the shoulder servos. The extensions are Al, and connect the front and back. I also spaced the back cover out about 4 mm to give the wiring better clearance.

I also built up an external battery pack from some 3000mah nicads I had left from my battlebot. Lots of capacity, but I think I need to make the tether out of more flexible wire. Got tired of having to charge the small pack so often.

Yep Cool stuff i am liking the head and the Blue sections,All ready for when the Blue brackets come out from Hitec.The gyro mod was more work than it would first appear,but isn't that always the case.These seemingly simply mods can sure eat up the hours, But clearly worth it. :lol:

Hi rep001,

These seemingly simply mods can sure eat up the hours, But clearly worth it.


I just carried Zembots idea a little farther on the gyros. The head has caused a small problem, I now must modify the programs to acomodate the extra height.

The wonderful thing about time is that there is a lot of it. I retired a year ago, so now I have time...Although I think my wife is trying to get me from underfoot, as she bought me the RN as an early Christmas present. She just retired this year... :D
