2 years.
Some blame the manufacturer, some blame their ordering and lack of foresight. They reigned in a LOT after the 408 - they bought so much stock. Personally I think they are too conservative but they also have so many parts (along with new parts) to buy and it's a tiny company.
No doubt right now they are running at a loss since they are working on so much new stuff - with the ARRMA brand also.

They just need to make a few more things like a 410 centre diff conversion (I made one 2 years ago), small bores back - with ally shock caps. Old style 410 shock towers (much stronger). Then a centre one way, front one way and overdrive option.

Personally I think they missed a trick with the centre diff on the V4. Hupo showed how to gain the room for it and keep the strength. My version was too weak to race but I'd really like to race that centre diff on a bumpy track.
