I am no longer affiliated in any way with TechnosModels. They basically took all of my electronics designs and are now selling them as their own. They had promised to send me a box full of prop electronics that had been professionally assembled and I was going to use a lot of these to settle many outstanding orders. But after promising me several times that the box had been shipped, it never arrived. They also promised to pay me a royalty for every sale they made. I agreed to let them cover their manufacturing costs first before they started to pay me royalties. They told me they would only need to sell 10 of each type of prop electronics to cover the initial costs and then they would start paying me royalties from 11 onward. Many items have sold well beyond 10 and they have not paid me a cent. They lied to me several times and so I left. They continue to sell the electronics against my wishes. They refuse to listen to me.
Sorry for the rant. I did not mean to hijack the thread.
As for the battery: yes, I can supply a new rechargeable battery for $25US. PM me.
