    Default I need a gear set for a vintage Graupner Hydrospeed 500 drive system

    As the title says I need a gear set for a vintage Graupner Hydrospeed 500 drive system. My gears broke the first time I tried to run the boat.

    I’ll have a look tomorrow buddy. I may have them. I remember seeing gears somewheres. Just not sure if they were graupner or not. I used to run their stuff

    Well I looked and couldn’t find any. I wonder if my old hobby store would have any old stock? Maybe. Back in the day I changed mine over to a belt drive system, it was so cool sounding. Hyperdrive was where I got the parts. The Graupner shafts were common 4 or 5mm so matching up is easy.

    Thanks for looking! I have been searching ebay for months now. I remember the old hyperdrive belt systems, I will add that to my ebay searches.

    Hey I’ll see what is going on with the old Portifino Graupner boat that I built in yesteryear. My moms male friend wanted it but pretty sure he was just after the 4ch radio. The boat has two of those drives in it

    I actually might be interested in the whole boat minus the 4ch radio, I always liked the lines of that boat. I could use the gears for my project and retrofit that boat with a newer drive system.
