The rubber band idea as I posted works on big models as well as small. I have it on my 15cc powered Skymaster Bipe .... and I've seen it on much bigger models.

The beauty of the set-up is that it's easy to fit, the rubber band can be increased or decreased as you want, no load at all on rudder, gives excellent shock absorbing, totally adjustable ... a pack of standard rubber bands from local shop will last you years ! The set-up is barely visible under the rudder so has cosmetic appeal as well .... sorry Chellie but a dowel and band round with a great big arm as well ? Not exactly nice looking ? To be honest with that - I would elongate hole in arm, stick a headed pin through into rudder base instead of the rubber band etc.

For those that don't believe the band idea is strong or secure enough ... on 30th Oct. - I had no bands in my box and one on my big Bipe had broken ... no worries. She tracked straight based on rudder and a free tail wheel. All I lost was the ability to turn on the ground.

I've modified many of my models years ago to this system ... it works.


In fact to original poster ... why fiddle with springs ? that give you little or no adjustability etc.
