Weren't they the old ones that went up to 4s or something?

Makes my life easier though anyway, running them on 3s is a lot easier than 4, probably...

Plans today were ruined by nature/life so I'll get started properly on this beetle this week. It almost certainly won't be in weight on first build, but hopefully will be able to refine it a little to get it into a battle-ready state at some point. Will try and bring this one to Stevenage where the HW champs are (?) in the inevitable absence of the other two bar spinners.
