What's the T2 spur like? can somebody take a photo? It's probably on a 5mm shaft right? looks like it has a slipper plate on both sides?
Eye-balling it looks like a 44T or so - how close am I?

[link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXNPR4&P=7]Savage X spur in 46T[/link] looks like it could fit with a trivial amount of effort, just stick some slipper pad material to it. Peel it off the Volcano spur if you need.
