I'm just in the process of building a 12S 550 and wanted to support the pinion to help look after the motor and main gear.

I've used a KDE pinion support (intended for 700E conversions) which fits quite nicely. However, in order to mount the Align 600MX motor using all 4 M3 bolts I've had to make a custom motor mount.

The mount is very similar to the standard Align part, but has a shorter cut-out section (reduced by 4mm at each end). I've also added two extra M3 slots for the extra mounting bolts.

The new mount only really accepts the 13T slant pinion, anything bigger or smaller might require adjusting the cut-out dimensions.

The final fit into the frames isn't bad, there is a slight encroachment into the battery tray but only by a few milli-metres.

Can't wait to get this thing finsihed and in the air!

I am interested in how you mount the two batteries and what size you use.

Two 6S packs side by side on the front tray. I not yet tried this my self, but I've seen it done so I know it works.

As for the pack sizes, they will either be 2700 or 3000 mAH OptiPower packs. The plan is to share these packs with my 500. Both pack types fit, but obviously the 3000s will be slightly heavier...

I need to decide soon as I'd like to order up the batteries ready for the Spring.
