Another toy, this time a Kayak, bought in a Brest toy/model shop 18 years ago 15€.
Had a crude r/c system installed, forward/reverse and direction, single speed! Another for bath time.
Opened up the kayak to view the r/c system, room for a 27mhz system, which was duly installed using a home built speed controller and mini steering servo. I should have said, there is a rudder under the rear hull for direction, the paddle push rods just operate in a vertical oval pattern.
Another for use by children at exhibitions. Ran well for 2 or 3 seasons then locked up, investigation revealed a gear box with stripped nylon teeth. I had a g/box with brass gears originally destined for a 00 gauge diesel loco! An adapted modified mounting was made and installed, success!
Continued in use over the years with upgrades to the r/c system etc.
The last time out whilst packing up a tx fell on the paddling mechanism and the two push rods were broken. Have not opened it up to assess the viability of a repair, but probably a goer as the system is in abs plastic so with plas weld or similar it should soon be back in action.
I also need to produce a rubber seal for the paddle system etc, I have a wooden mould for this, and with talc and latex solution shouldn't be a huge problem!
I will post more photos of the internals etc when I get around to making repairs.
