Schempp-Hirth 'Standard Austria' control surface balancing

[Matt G.]

Does anyone have any information regarding a balance spec for the ailerons and all-flying tail for the Schempp-Hirth Austria gliders? I'm refurbishing an SH-1 and I'd really like to make sure that the balance of the control surfaces is still OK since several layers of paint are being replaced with one new layer and some repairs have been made. The US Schempp-Hirth dealer, M&H soaring has been no help, and emails directly to Schempp-Hirth have gone unreturned. I've polled several other people who own an Austria and nobody seems to know the answers.

Hi Matt
you could try the UK main agent - Southern Sailplanes
email address is they've
been very helpful with any info regarding our SHK.

There might not be any specs on your Austria, The H-301 Libelle never had any specs and an AD was published that said to weigh each control surface and the trailing edge weight and use that info as the specs for each bird. Removing several layers of paint is always good because it reduces the GW and TE weights.
Hope this helps,

Hi JJ,

Didn't see this until now...I thought I was supposed to get emails when someone posted in threads I'm subscribed to. Anyway, that looks like what I'm going to have to do. Mike's suggestion didn't work out; Southern Sailplanes couldn't dig up any information for me.
