Vario MD500E 1/5 Build

From a cost and reliability perspective I found the TREX 700E mechanics to be a solid performer. In particular I used the F3C version as it does NOT use an AR bracket on the swash. The Elevator swash link is designed to replace the AR bracket and this makes for a much cleaner scale look at the rotor head (IMO).

The slide out battery tray of the mechanics also presents a convenient tray upon which to mount the RX and AXON FBL thus allowing for quick and easy access as well as a compact and clean set up.

The ability to customize the length of the servo leads is valuable allowing for a tidy routing of servo wires. I recommend investing in a good set of servo lead crimpers and quality servo connectors.

The mechanics require a platform to place them at the correct height for the tail boom and rotor head clearance. This presents a convenient location for the RX power switch and 'Arming' plug I use.

A had a local print shop do up the decals that label the switches.

The platform is a top plate and a bottom plate attached via Standoffs purchased from an electrical supply site (Mouser). The standoffs allow for a mechanical connection all the way to the floor joist mounts. The side walls of the platform are attached to wooden posts placed along side the Standoffs.
