I'm looking for a steerable tail wheel which doesn't have to be fixed to the rudder directly. If it can fit onto the snake rod or rudder horn that would be better but I don't really want to disturb the rudder covering.

Dubros do one with a sprung connection to the rudder horn. Try SMC they tend to stock a lot of Dubros stuff.

Lots off artf's do one that has the tailwheel wire held under the rudder by a small plastic bracket easy to copy, black horse models usually have them.

This is how it is done on the SLEC Funfly, a brass loop with a length of fuel tube as a shock absorber:


Simple and effective!

Hi Trebor,

I have used the ones from Sussex Model center and SLEC and set them up as you want to.

I would be careful that the tail wheel steering connection is independently sprung to avoid shocks to the servo.

I wouldn't trust a piece of fuel tube to give enough "independence", but it depends on whether your strip is tarmac, billiard table golf grass or the average mown farmer's field.

Now you tell me about springs sad. I went on a rummage and cobbled this up. I didn't want to spend too long repairing it so I glued the ply on the bottom so I didn't damage the covering too much. I thought the ball joints might pop off if there was a bad landing or nasty hole on the runway. You can see the bottom of the rudder missing, this is the second used plane I have with tail wheel problems. The rudder always seems to get it and the skin at the base of the fuselage has no strength for attaching the wheels to.

The scale-type tail wheels sold by HK seem to be OK. I fitted one to my last build (60" ws electric conversion) and it's survived half a dozen landings so far - and the last one was less than perfect The connection to the rudder is via a pair of springs to a suppled bracket. That should be reasonably durable but whether the plastic arm supporting the wheel is equally so remains to be seen. It all looks very neat, though.

The collets are a bit big but I filed a flat spot on piano wire wheel arm so they lock up ok. If it works I'll get some correct size ones. I might have to make more alterations yet but the lack of shock absorbers on my servo is worrying me now.

That looks good Geoff, it took me hours to find the bits and make mine. Have you a picture with it on the plane, just thinking about the missing bit on my rudder.

Well, as a thunderstorm seem to be brewing and I don't fancy to go out on my bike as I intended, here you are:
