Ranglebox and HDPE for Featherweight construction

[McNally]

Hi there,

Me and a former colleague are wanting to piece together a featherweight. I've had a quick look round at some off the shelf gearboxes and noticed the ranglebox motors and matching gearboxes.

Does anyone have any experience of using the RB-775-18v motor in featherweight competition? Would two of these with the matching gearboxes be appropriate for a featherweight? Or possibly overkill?

Also, I was thinking screwing the gearbox directly to a board of HDPE and using aluminium nutstrip to hold together the angles and work as a basic chassis.

Could this work, or do people think it would be a little to fragile?

Cheers,

Gary Mc

I'm a newbie too. I keep hearing concerning things about HDPE in relation to impact damage from spinners and huge axes.

Apparently there are only two events which allow featherweight spinners so they aren't as big a problem for feathers. I am using HDPE for some less exposed parts and internal bracing, then Polypropylene for the top and bottom which are more likely to get axed.

The Saturns from Ranglebox are powerfull and almost bombproof drive units. But will demand creative design and build to cope with the weight.

For "just enough" the Neptunes are a better option.

HDPE/nutstrips. It works, and is rather easy to implement.

PP is harder and more brittle than HDPE.
