Pete B Posted August 23, 2013 Share Posted August 23, 2013 Assuming that the wire pin is facing the same way as the wheel leg below the tailplane, then drilling a hole in the front of the rudder is the way to go, bren. When you do so, cut a groove in the face of the rudder deeo enough to accommodate the vertical part of the shaft - this will ensure that you can fit the rudder close to the fin - you don't want a big gap there. Use epoxy to fit the shaft into the rudder. There should be a bracket at the rear end of the fuselage, through which the shaft passes, and which will support the tailwheel assembly. Be aware that some shock loads will be tramsmitted to the servo through a rigid connection, so it would be worth considering something like a 'servo-saver' which will absorb the shocks.

bren Posted August 23, 2013 Author Share Posted August 23, 2013 could of made a hole for me lol its pretty thin will it hold ok? Quote Link to comment Share on other sites More sharing options...
Pete B Posted August 23, 2013 Share Posted August 23, 2013 You're lucky you didn't have to cut and cover the rudder yourself! You'll need something like a 2mm drill bit to gently bore into the wood. Once you have epoxied it in, it should be a little stronger but there will always be a potential weak point. If you want to make a belt-and-braces job, you could strip off the covering from the lower part of the rudder and make a thin sandwich of, say, a 1/32" ply plate either side. With the rudder horn bolted through the plate, that would make the whole assembly much stronger. An example of the servo-saver is shown here. Similar types are available, too.

Pete B Posted August 23, 2013 Share Posted August 23, 2013 Glad to hear you've the most important bit of kit in your toolbox - a sense of humour - you'll need it! Looking at the pics on the HK site and elsewhere, I can't clearly see how the rudder is controlled - is the horn fitted to the bottom right side of the rudder?

Wingman Posted August 23, 2013 Share Posted August 23, 2013 Sometimes the covering covers the hole and groove - worth probing with a pin to see if that's the case. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted August 23, 2013 Share Posted August 23, 2013 Good one Wingman, but if not, I second Pete b's suggestion re ply re, enforcements as the rudder will soon deteriorate. Cheers Quote Link to comment Share on other sites More sharing options...

Pete yes it has a horn each side which also doesnt have holes lol Quote Link to comment Share on other sites More sharing options...
