What a transformation! My wood should arrive today so that I can start on the beefed up motor mount over the weekend perhaps. Working out mounts for servo and ESC I’m looking to incorporate blue anodized aluminum removable mounts instead of ply constructions. Hopefully it will come together and look and work effectively.
I’m going for a twin arm connection to rudder servo for push and pull to avoid issues if pushrod bends on the push. I notice most seem ok with just single link though?
]I’ve also gone for a higher torque servo as I’d figured the forces on the rudder at speed could exceed the regular servo capabilities but perhaps I’ve gone OTT!
Thanks Stuw,
Last night I plugged the letter-box type slot that was left when the large P bracket was pulled out and cut some dowel to plug the holes left by the rudder and the water pick-up scoop. The hardwood plugs have all been made a "force fit" and tapped in with a hammer after coating with 24hr Araldite. When the epoxy has dried I will saw off and sand the plugs back to give a smooth finish to the underside of the hull.
I use a 3mm push-rod with an anodised alloy captive ball joint to connect the servo to the tiller arm. These red anodised rod ends can be found on the Bay and they give a really trick looking linkage - but I have not seen them in blue. 3mm threaded push rods can also be bought from the same source.
A bent 90 degree end passes through the alloy servo arm with a 3mm collet underneath to hold it it place - on some fast boats (like the Blackjack 29 I have just listed on the Bay) I go one stop further and fit the FG throttle override device to give fast precise adjustment too!
You could use an alloy ball joint on both ends of the rod if you use 3mm threaded studding (or cut a 3mm thread on the end as required) to look super-trick!
The 3mm push rod is rock solid, so if that should ever bend the rest of the hull and/or rudder must have taken a massive hit!
I also fit fast high-torque metal geared servos for peace of mind as much as enjoying the fast steering response. OTT maybe - but nice
