I was at the field today between 14:00 & 15:00 all on my own , good flying too. There is a dead sheep along the fence line towards the gate from the pits, I saw the farmer so reported this to her. I hope no one had plans for a BBQ Smile .

Morning all.

On larger models, they quite often have a tailwheel that is conencted to the rudder, with some pretty long springs. Does anyone know where I might be able to get hold of a couple of these springs?

Secondly, is it normal to just bolt a small bracket to the underside of the rudder, to link the springs to? Or would it be better to mount it to the control horn , along with the pull-pull cables?

Andy

Not sure where you'll source the springs ,Rich may know, if all the angles work ok I'd connect them to the same horn as the pull pull cables Wink

Aldi did a pack of springs a few months ago, some sutible ones in there, may be worth a look to see if they still have stock!

They have suitable springs Tailwheel springs Icon_bounce at Model Exchange Greenfield.

Although an easy fix, the bracket off the rudder is, in my opinion, a crude solution. In my experience, the rudder (and linkage) inevitably get damaged from the strong leverage of the tail wheel on the rudder, on arrival, particularly on grass.

The alternative is don't bother, just fit a skid or fixed/castoring sprung tail wheel. After all it's, not a tarmac runway your flying from but basically a cow pasture. It will still taxi OK. Assuming of course, that you do land on the strip! Tailwheel springs Icon_lol

Or you could install a dedicated link from the rudder servo or even a separate servo.

The whole idea of the said springs is to prevent such damage Paul. personally I wouldn't fly a large petrol model with just a skid unless it's a scale jobby Wink

Aye, that's the idea. Springs to act as a great big "servo-saver" link. I'll have a look in the model exchange though, I'm heading that way later this week....

Cheers

Have you got any about 150mm long Rich? I might have to come and swap a couple of them for the 50p I owe Wink
