I have worked extensively on both Cessna Cardinal and Beechcraft Duchess landing gear.
The Cardinal is a fickle bugger that requires you to pump the gear down in case of pump failure. If you pump to many times and the over-pressure valve sticks, it snapps part of the apparatus off and you get to make a gear up landing. The Duck's gear is spring loaded to the down position. Open a bypass valve and it pulls itself down right quick. Coupled with the previously mentioned boat motor hydraulic pump you would have a nice light and safe system. $.02 Jeff On 1/23/07, Martindale Family <johnja...@optusnet.com.au> wrote: > Try one of the small boat outboard motor hydraulic systems that raise or > lower the prop out of or into the water.
