I used pull pull on the rudder and elevator, with the servos near the bottom wing hold down block. Didn't use real diagonals between the interplane struts because I set up my struts to fold against the bottom of the top wing. but I did tie some elastic thread between them. Lasted about one season.

For all strut and wire attachments, I used Dubro steel clevises and .03" brass sheet fittings. that way I only have to unsnap 3 strut clevises on each side and 2 flying wire clevises on each side after bolting on the wings.

here is my build thread at the page with most of the fitting pics. (along with the compartment holding the 5000 mah A123 pack)

Hello Folks,

I'm not sure if I've asked this before but i'll ask anyway haha. Are the flying wires on these functional or not?

No. Don’t forget that the wing struts are!

Oh for sure. If the wires aren't functional it just makes it a bit easier to design a quick connection method to make at the field assembly much quicker smiley

I’ve used clevis links and nylon fishing trace wire. Just a simple job of unclipping everything. The “closed loop “ on the aileron was just black elastic.

The servos were just in front of the tailplane, weighing 240 gm, moving them under the pilot has reduced the ballast by ~ 400 gms

Huge difference!

It’s surprising how moving “useful “ weight can reduce the need for ballast.

Laser Jon,

If you are still tuned into this thread - what size Oleo's did you use for your sprung undercarriage?

Many thanks.

The OD on my Oleos are15mm. I found its more important to get the compression rate and spring size correct. I used trail and error using various size springs and combinations.

Ive used Flexo Springs in Bristol on a few occasions, just had what I wanted. It was £6 p & p a while back

I used 169mm HKing alloys struts 60-120class. A little long but at least they were in stock (took a loong time to come). A little long but easy to cut a bit off the tops. I dismantled them and put a short length of hardwood into the oleos to shorten the travel a little but firm up the compression. Probably be better with slightly stiffer springs tbh but can’t be bothered to search for an alternative. Kudos to Cymas for his work in finding the best springs.

I chopped out the axles with part of the legs supplied in the kit and used those as the angle was already set. The bottom of the oleos was drilled larger and at an angle to accommodate them. Unfortunately the axle stubs were then too short and although I cobbled a solution which worked for a while I have since made up new parts that are much better.

Thanks to everyone who's been helping with sharing info on engine installs for the Stampe that I'm refurbing. After a close flirtation with the idea of an OS GF40 (thanks to Alan Gorham for all the info there) I've decided to go with a Laser 180 - ordered today from Jon.

Jon - would you mind please posting me a link to your photos of engine baffling etc. and also to the revised u/c you've installed.

Nice choice Adrian, I have 2 lasers and they are a delight. Saito 180 in my Stampe which is similar regarding reliability and sound. Enjoy
