Some of these links are posted elsewhere on the forum, but I thought I'd collate them in one thread for future reference.

Great stuff Russ,

On my first very old Futaba FF6 (which now lies in the shed), the instructions had a similiar set up guide which I have followed with great success. This one seems even more concise. I'm convinced accurate aerobatic flying is 70% set up. A stall turn is pretty easy when all you've got to do is pull to the vertical then hit some rudder at the top, rather than constantly adjust in 3 axies.

Lost me a bit with the triangulation stuff though!

I think the triangulation method is the new kid on the block and has certainly grabbed the attention of some of the leading pilots.

The line that stood out for me in Pete Goldsmith's article is not to fly around the unwanted characteristics of a poorly set-up model. Investigate the causes and attempt to trim them out -  as you emphasise Mike.

When practicing the B cert schedule it's noticeable how much more straightforward the routine becomes if you get your CofG right, especially the double rolls.

This triangulation caper does rather assume it's easy to adjust wing and tail incidence, which mostly, it isn't. I'm sure pattern ships are set up to achieve this easily but most throwabout ARF's are not.

Russ,

Great links, i will have to try the Triangulation stuff out on a couple of my models, some will be easier then others.

I think the hardest bit when doing all the 45' up lines and loops is ensuring you don't put in any cross stick inputs in. When testing the loop its very easy to add a bit of aileron (i know as i do it consistently), perhaps a buddy box with one person on elevator and on on ailerons would work well.

Are you entering the loops level? As one of the articles points out, a common fault is to fly what you perceive to be level with the inside wing low. I'm fairly sure I'm guilty of this trait.

Are you entering the loops level?

I know I'm not always entering level but i also do know that i am putting cross stick inputs in. Its very easy to do and takes a lot of thought to stop you from putting them in once you start to make them.

This is something i will have to try and work on.
