the answer to your question is yes. i and many others have put the tamiya electronics into heng long and other bodies. I have 4 units using Tamiya, two with El-Mod, One DGS ready to install, and one "Darkith unit" installed and two ready for installation. it is very easy to do and is very modular if a bit bulky. the el-mod system as Blitz will elaborate is a group of smaller packages that has a more extensive range of capabilities and is a bit smaller over all but there are a few more cables. The el-mod system is about 50-20,0 bucks cheaper depending on your sources, and has a much better selection of sounds representing more types of tanks plus custom recording capability.

El-mod is compatible with tamiya battle system (send, receives hits between systems). it is a German product.

Which is better? IMHO For overall capabilty the El-Mod, for ease of installation- the Tamiya system. Which is more inexpensive and has greater growth potential - the El-Mod.

Back to you Blitz
