Wilga ucart

Post by barrieburton34 » 28 Feb 2019, 09:36

I need to find a supplier of small shock absorbers as used in the undercarriage of my Wilga.It is the usual 2.2M span. Eye to eye extended is about 110mm.The shocks that I have are that weak that they bottom by the weight of the model alone.I have tried adding external springs but that does not solve the problem. Any help appreciated.

Hi Barrie
I have used both Associated Spring and SGS engineering. See if you can find something there

Thanks for the reply Ray,I have downloaded the Associated springs catalogue.Do not have a clue yet to prices,or will they sell me just 2 off.Work in progress,as they say.Your photo shows a Wilga,I assume you have one,if so does it have the slots? I purchased an unfinished glass fibre fus,tail ,cowl and ucart,but no wings.I have built a set of wings with slots,but have noticed that a lot of the ARTFS do not have them fitted,I hope I am not asking for trouble.

SGS will rework the ones you have I think, also, if you're not happy with the result, they certainly used to offset the cost of new ones too.

Hi Barrie
Mine was a 1:3.5 scale Frish Wilga which doesn't have slots. Sadly it is no more after a flap failure last year. I am guessing that yours is the 1:5 scale version from Airworld which does have slots and a whole lot of other detail on the wing. The Frisch kits were more a working model. Again sadly I believe that Alex Frisch has given up kit production now, though he wouldn't export to GB anymore anyway.

See below for details of the Airworld kit

Hi,

If this helps: My 30% Wilga 2000 weighs just under 20kg and is fitted with SGS struts. I've photographed them so you can see the reference number and rate. I find these are about right. A good rolling landing and they move very little but will bottom with a less-than-perfect three pointer.
Cheers,

John

Whilst we're talking Wilga 2000, here's a video (one of several) about Draco, which is a converted Wilga 2000 to 680 shaft-hp Pratt & Whitney PT6A-28 turboprop and mega power. I like the hanger parking at 15 minutes, just cool 8-)

Thanks for your help and interest.As a temp measure I have beefed up the old shockers with coil compression springs.The model is ready to fly and I am more than a little worried.The model does seem to be an Airworld production.My model weighs 18lbs + but according to the Airworld web site 16lbs is about right.Looking at the Airworld photographs,their version does not have slots,mine does,hence the trepidation.
I liked the video.When my toy flies I will let you know.

Dear Wilgaboy,

Yes, this is the Wilga 2000 Colin built. It is still going strong tugging all day at the recent Camphill Tow meeting. It is a joy to fly. I told Colin so myself last time I met him.

Cheers,

John
