Default Grob SB's

Anyone paid for access to the Grob web site for SB information. In
December
they introduced the charge but now have had to make it free as they are
required to make the information available to A/C owners. But guess what,
they don't want to refund those who have paid as it gives access to FM's
&
MM's even though there was no option just for SB's. Greedy or what!!

I'm glad that they still find it worthwhile to make ADs when needed.

Like to see a TN and parts to change the retracts to a fixed gear.

LTB Lindner has been asked that a number of times. Apparently,
they have no interest in doing so.

How much, if anything is there in common between the fixed u/c mounting
structure in a Twin Astir and an Acro II?

Just a thought inspired by the apparent ease with which the early Libelle
201s could be converted from fixed to retractable u/c.

Are you referring to SBs for pure gliders (G102, G103, G104) or motor
gliders (G109, G115, G120)? There are two completely separate support
organisations involved! Gliders have been supported by ltb-lindner since

2010, the motor gliders by the latest manifestation of Grob now called Grob

Aircraft SE. Two companies, two attitudes towards their customers.

It's motor gliders and I agree two completely different attitudes.

Completely different animals. A number of owners have investigated this, and it's not a simple issue at all. The structure is completely different as well as the mechanicals of the wheel, mounts, etc.

Several operators I know of have pinned the gear in the down and locked position. We'd all love to reshape the rear seatpan, but it's integral to the structure and would require an engineered solution.

Fair enough. I've flown both Twin Astir and Acro IIs, so it seemed
possible that replacing the folding undercarriage with a fixed one on the
same attachment points would have been an easy job, and cheapish too,
since it could reuse tested structure in an, apparently, very similar
airframe.

I should have looked at Martin Simon's book "Sailplanes 1965-200" before
opening my trap: it describes a complex lay-flat retract system which
almost certainly could not have been easily replaced with fixed gear.
(Takes foot back out of mouth).
