This is a support hinge for the Meihou Trendy 8200 and Kyosho Pit Box, popular among Mini 4WD racers. It was ultimately completed as PTC11, but what is being offered here is a prototype from the final adjustment stage of the design. It will be sold at a bargain price, so please consider using it if you'd like. ・Support Hinge Set: Upper and lower base plates (1 set), folding arms (2 sets) / Screws (M3 screws x 4, washers x 4, spacers x 3) ・The specifications differ slightly from the final product, but the basic aspects are the same and can be used without any problems. ・The filament used is PETG carbon fiber (black). ・Please refer to the separately listed PTC11 for usage instructions and basic specifications. ・M4 screws for fixing are not included, so please prepare them separately. (4 screws, 8mm or longer) ・A Pro Arm set will be included as a bonus. Please refer to the separately listed PTC11P. ・As it is a prototype, there may be some localized defects. Please check the specifications and condition in the photos. Since it was made with a 3D printer, there are individual differences such as layer lines and localized unevenness. Those who are extremely sensitive to the appearance, please refrain from bidding. Returns and support are not available. Please bid with the understanding of the above.
