Hi Fede, I've just had a week on holiday so no progress to report!!

Yes, I have used that company but only for small items like metal rod, I am sure they would help you.

When my MN is finished it will have a Spektrum 2.4 ghz receiver (possibly a simple AR500) and JR NES291 servos for the fuselage. I have not decided on wing servos yet but will probably be Hitec.

Cheers

Gary

The Duster brakes rotated about a torque tube in the brake.

The Mini dive brakes were spectacular and speed limiting - you could safely do a true vertical descent with them fully deployed.

The Duster brakes could be best described as wimpy - but the plane did side-slip nicely.

I owned both a Duster and a Mini-Nimbus....

The Mini Nimbus is a very special glider type to me as I owned and flew a full-size one for 20 years.

I have wanted to build one of these for ages and it will be my next project, hope to start building in a month or so.

The kit is fantastic quality, I have one small gripe with it though; the outline is not very scale. The forward fuselage is much thinner than it should be and the tail system rocker mount is a bit of an eyesore but model designers have to make compromises. Won't even mention the lack of trailing edge airbrakes!! Shall not be entering any scale competitions with it so who cares?!

The plan is to build it exactly as designed, the 'Variopop' linear servos might be difficult to get hold of though!

Some photos.

I have been searching all morning for these. I first saw them on www.rcaerotow.com. See attached. I stumbled upon your post and the Lande-Klappen look to be the same. Can you tell me where to buy these?

Hi Jim, got your PM's thanks.

I believe this item is discontinued. Try searching for 'Graupner 93', they do come up on eBay sometimes, I'll look out on the UK site for you, they are probably more common on eBay 'de'.

Search there for 'Graupner Raritšt' or 'landeklappen'.

There is a Mini Nimbus kit on there at the moment, 301 Euros and climbing!!

No progress with mine recently, busy painting the house and making the most of the summer!!

Cheers

Gary

Great job Gary !

Very happy to read and see the pictures. I still have one from 20 years ago. Only one leading edge and wingtip to glue and polish and it is ready to cover ... with real silk and dope. I hope I will soon find the place and time.

You will be as happy to fly it as to build it.

Cheers, I thought Antwerp was in Belgium? Went to the TT races in 1982, good times.

This build is on hold at the moment (building other stuff) but I was able to help out a friend recently who needed to build a tailplane for a Cirrus 75, it's the same apparently.

Jim got his airbrakes BTW, I found some on eBay in the UK and the seller was kind enough to post them to the States.

Post some photos if you like (and welcome to RC Groups!).

Cheers

Gary

Alloy Airbrake Servo Operated

These look very similar in construction and function to a set of Graupner Teck-Doppel-Landeklappen System Schempp-Hirth that I have. All of the Graupners are very hard to find and these are available on Hobby King's site here: http://www.hobbyking.com/hobbyking/s...dproduct=19609

The blade length of these is about the same as the plastic Graupner Lande-klappen at 10".

They look like clones of the full scale ones.

With winglets no less! An aftermarket modification. The Mini Nimbus is a good glider but what it really needs is another 10 metres of span!! Always ran out of daylight in mine trying to get home!

The current Graupner brakes are easy enough to get hold of, Graupner 93 is the spoilers mentioned here (they are plastic flaps that hinge up from the front) are discontinued but people still have them in their lofts and sheds.

I'm pretty sure that you can build this kit without the spoilers, I found some mystery numbered pieces of balsa sheet which I discovered was a blanking panel for the spoilers.

Must get back to it sometime.
