From the bits I've heard regarding shop supplies, TD are tricky to work with, limiting shops quotas of kits and supplying only a small percentage of shops requested numbers.
I love TD cars, but can't help thinking they are letting everyone down a bit. The cynic in me would suggest as they know demand is high (and they have a good customer base thanks to shops that supported them...), they are moving to a businees model where they are limiting shop supplies to force customers to buy direct from TD, that way they make a bigger margin per kit / spare etc.
TD must have known the approximate demand for the V3, if they got it very wrong, then fair enough - still a schoolboy error. 210 spares anyone

(ok I know they are finally filtering through

)
Come on TD, sort it out and support our local hobby shops that are the lifeblood of this hobby
