Anyway I plan to do this topic a bit differently as I am patterning it to be a detailed build diary showing all the steps (and mistakes) I will make customizing this baby. Please feel free to comment as I will need every info I can get. I will also be asking you guys questions if I hit a road block during the process. I am hoping that this will help the other beginners interested in this hobby as well.
The panther G I bought is the smoke and sound model with plastic tracks and fires the BB.

I noticed the muzzle brake has a hairline crack. I guess the assembly guys in Heng long screwed it a bit too tightly. Does your HL panther suffer from the same problem. I am thinking the plastic they used is a bit soft. Are there brass muzzle brakes for HL panthers?

I plan to do upgrades first before detailing it. Here are my plan steps.
1. Add weld lines - this is detailing but since i think it fairly easy to do I can probably do this first while waiting for the upgrade parts to arrive.
2. Metal Tracks, sprockets and idlers
3. Stiffer springs - I will buy this part rather than adjusting the stock springs since I am a bit wary of making a mistake during the drilling part to re-adjust the stock springs
4. Engine grilles -
5. Mato 3:1 brass gears and motor
For the last part I don't even know if the tank I bought has plastic or stock metal HL gears. If its metal I would probably defer item 5 since it can be quite costly.
Which brings me to my first question. How do you open up the tank? I turned it over and counted 10 screw holes of varying depths. Do I have to unscrew all 10?
