Thanks Doug ,Will do. Thanks for your help Sid

Mornin' Donnie, at least it is here on our side of the 'pond',
Many thanks for the appreciation 👍
It's sort of an extension of my profession (in miniature) into my retirement.
I used to design / develop radio equipment and later full communication systems. The last 32 years specialising in COMMS for naval ships.
I would do the initial system design to the navy operational requirements and then negotiate the refinements and inevitable upgrades and changes with the navy and/or shipbuilder. Sometimes dragging them up to date in the process 😉
Wish I was in Canada too! I designed the COMMS refit for the RCN MCMVs (Mine Counter Measures Vessels) several years ago. Also worked in Newfoundland with Provincial Airways Engineering on the mini AWACS planes they were converting for UAE. Enjoyed both projects and the great people I worked with very much.
I still do my research the same way as then; if I don't know how something works, I find out double quick! Only way to stay ahead of the end user - and the competition 😉 Very glad you are finding the site useful 😊
Cheers, Doug 😎

Maybe they don't make that precise one any more, but they have a vast range so check out the specs for an equivalent, or very near to.👍
Good luck, 😎

Doug,I have been following your posts.I have learned quite a lot from them.Too bad you are not here in Canada.I'm always trying to get more people to access the model boat website to gain more info on problems they may have.Also to see what other modellers are achieving.Keep up the good work,it is very much appreciated.

Hi Doug, Yes ,I have tried there . They do not make them anymore. My only chance is that someone may have one that they have discarded. Sid

Have you asked here?
