Can anybody tell me if P/N 0402-591 SE main gear 77T ($50) & P/N 0403-219 main gear 77T ($6) are interchangable?
Its for a CH-47 Hirobo Chinook, manual P/N is the 0402-591.

The 0403-291 is an older main gear for the likes of GPH. I would put money on it being larger diameter. Being so cheap it would most certainly be the black plastic (not stronger than the white Shuttle gear). You should try the Sceadu Evo 50 standard main gear. If you can make that fit you could use the hard delrin white gear. The ratio will be lower for lower H/S. Are you stripping main gears?
