About these kits:

The parts are CNC machined by me, a mix of aluminum, G10, and delrin. All the hardware and fasteners are high quality, from grade 6 to 12.

Made in the USA! Here in Texas!

Kit Options:
1. G10 color (black or blue)
2. HS-65 or HS-56 servo mounts
3. 1 motor pulley included - sizes: 10T, 11T, 12T, 14T 3.17mm bore

I can get 3mm bore or 4mm bore pulleys on special request.

I will resume white delrin and there will be a new selection of blue or red anodized screws in the future.

3 months of testing / revisions: HOSS x4 THREAD

 

A little history:

The Hoss x4 frame started development phases of the belt system back in Nov 2005. The first prototype version was flying in Feb 2006. It had two motor mounting spots for two different belts, and the battery was mounted up front in the belly. The stock Landing gear bolted right on. After a few weeks of testing I decided that the frame needed a major design overhaul so I could make it as univeral as possible for motors, batteries, servos etc... The frame was originally designed for HS56 servos. But with the release of the HS65's I designed new mounting plates to work with the frame in the late spring of 2006. The design was changing everyday as I worked on the frame. People that I knew kept asking me, "when is it going to be done?" I Just kept saying, "soon soon!" After months of design, and not to mention everything else involved; the version 2 protoype was ready to be tested at the end of August 2006. Durring testing All the weaknesses and issues were taken care of to lead to the final version 4.
