Yep...I'm currently using Ni-Cd. Yah...maybe I'll take out the battery bay and switch to Lipo. I have a couple of them which I use for my Blade CX2. As for substituting the elmod speaker for something else, never thought of that [X(] because after hearing the sound that came from it a few days back, I really don't think anything will match it IMHO. It really sounds very solid (like Altec Lansing PC speakers [sm=thumbs_up.gif]) because of the boombox. No matter what, I'll try to remove the stock speaker and squeeze it in...
The potentiameter is for volume adjustment of the speaker. The gun LED (any LED) can be easily connected to the TLS module via a connector. I did thought of removing the airsoft gun too to make space, but the problem is - the entire gun elevation system will be affected because it uses the airsoft gun as a hinge to move the barrel up/down. Hmm...maybe there's a way to remove it without affected the elevation.
Yah...the Panzer III is very nice (my favorite thus far too), BUT wait till you see the PANZER IV when it is properly painted/weathered and running on metal gears and tracks, then maybe you will change your mind.
