Obviously the 1.5 pins weren't up to the job, so they have changed them to 2mm.
There might be some hand on groin gifted by god mechanics out there who've had no problems. Fact is many many people have had pins fail whilst racing. Which sucks.
One local racer's 410 caught fire because the pin came out (heat-shrink mod too), wore through the lipo case and lipo. Not fun.
It would only be fair for Team Durango to offer these revised parts for cost. Why not offer the discount, be fair about it and keep happy the customers who supported the business from launch. Selling for cost wouldn't cost them any money, just lost profit.
After all, should TD really be profiting from people having to up-grade TD's design issue?
If TD do the discount or offer even better, all guys on this board who want to pay full price, should be given the option hand over the extra cash to TD. Happy days
