LOL!
this pic is very old! Reaper332 is right, it WAS an isolated power suply made for the little 25x25mm fan i had on the RX18, because it was running on 12V
But this was not a viable solution, so i eradicated this and installed an 5V 40x40 fan, it is receiving tension from the RX18 itself.
about the roadwheels, I made my measurements before and after the reinforcement with putty. An entire plastic wheel (the two parts put together and without the axle norcountng the suspension arm) stands for 10g. After the putty was apllied they stand for almost 50g.
there are other topics in the same website related to my tank, this one has newer pics:

My tank has the standard RX18 electronics, but as i was VERY disapointed with the HL sound, i bought the USM-HL Beier soundmodul, and this thing rocks. In the previuos link you can see it. I also put two minicams inside the cat, one in the driver's visor and one looking by the coaxial MG hole, to be able to aim. And is all for now... the next project i've in mind is to amend the different flaws on the tank, including the centrer of rotation of the turret, also i'm making metallic frontal mudguards with working hinges, change the plastic molded tools for 'real' ones, and then repainting all the Tiger like the Tiki profile...
best regards
