Mike V over at RCHeliMag is reporting about a new version of the Protos from the Nirenberg toy show:
MSH had on hand a prototype of their upcoming Protos 450. The name may change but essentially it’s a scaled down version of their 500. It features the same unique single belt drive system that uses the same main belt to rotate the main gear and tail gear. How is this unique you’re thinking, well the pinion is actually a pulley. So the pulley/pinion applies power to the belt that runs the length of the machine from main gear/pulley, to the tail. It’s a pretty cool system that we reviewed last year. MSH is expecting a June release with a price competitive with other high-end 450 kits.
