Thread: Armstrong - Siddeley Lynx 7 Cylinder Radial Engine.
21/11/2013 17:55:31

I have just spotted this post several months later. I do intend to have the drawings available but not until the engine is finished and running which may be sometime in 2014. I would point out that there are a number of very intricate aluminium castings required for which I have all the tooling mostly in the form of silicone rubber patterns and moulds. The actual casting is best done by specialist foundries.

Before finishing the drawings I would like to have some idea of how much interest, if any, there might be out there in reproducing this fine historic engine in 1/3. I might be able to assist with the production of waxes but do have a full time job to see to as well!

All enquiries are welcome and I should be pleased to discuss this project with anyone seriously considering it.

Thread: Ignition coils for small engines
22/07/2010 19:20:51
Hi Dixie and John.
Thanks for the link to Minimag. Julian there was very helpful and sent me a new sensor which is now set up and ready to go. I shall remember your valuable tip John about keeping the HT well away. It could indeed have been a bit close and may have caused the trouble. Engine is now ready for start up so we shall see.

Hi. I'm new to this site. Re electronic ignition for small engines I have been using various modules on my 9 cyl rotary with a Hall effect switch. Recently I've been having start up trouble as follows: engine starts as normal,runs up to speed then cuts completely, all lasting about 3 seconds. You can repeat this ad nauseum but engine will never keep going. Frustrating as it has worked beautifully up to recently, flying a Sopwith Pup very realistically.
 
Lack of fuel was an obvious possibility but long since ruled out. Timing & plugs are  correct. I found today that the Hall sensor now doesn't work at all. So my questions are:
 
a) what happens to them to cause failure? 
b) might gradual failure cause the symptoms observed?
c) how do I choose a new one bearing in mind my knowledge of electronics is almost zero?
 
My current module is a Zenoah running off 4.8V
 
Any help much appreciated. Thanks
