Greetings all, Dave from RadicalRC.com here. We've got a new gearbox frame replacement for the GWS 300 and 350. I know there are several out there. Where this one differs is that it is flange mount, not stick mount. So, perfect for gluing or screwing to the side of a profile model. I'd like to offer two of them in this forum to modelers that will use them and show us how they worked out. The mount uses all the parts from your S-300 or 350 drive system including the motor. To qualify, first post a picture of the model you plan on using it on. Perfect would be an unfinished model that doesn't already have a stick mount in place. I'll pick two of them and have you forward your address for shipment. All I ask is that you post a photo after you've got it mounted and tell us what you think.
