Hey guys, let me start off by saying I am a noooooooooooob in the R/C tank world. Literally. I used to be heavy into building model kits, RC planes and boats in my teens so I am no stranger to the hobby, but this is kind of like a comeback since I haven't built or flown or sailed anything RC since high school. I've always wanted to try out RC tanks but never really bothered investing the time or money, until now. Anyway back to the main topic, I just got my HL StuG today, opened it up, plugged in the 7.2 NiCd battery into the smart charger, popped it under the tank, and I got the light blink problem- in the horribly frustrating yet hilarious broken English of the instruction manual it told me to let it blink for five minutes..... 15 minutes pass by and still no love from the stug. I figure it's the crystals so I bend one of the legs outward a little bit, still no love. I've done some research and found out that only Heng Long brand crystals will work on Heng Long tanks. I really don't wanna go through the hassle of shipping it back and waiting 14 days where I can just buy parts for it, take the baby apart and repair it myself (part of the fun!). Can anyone help me as to where I can buy replacement parts/ what websites are reliable (especially those HL frequency crystals)!!!!!!!!!!!! I really wanted to run the bad boy today too and get some real weathering on it.

Also I was looking into upgrades like metal gearboxes and tracks, wheels and such. So if anyone can help me, give any advice whatsoever, I'd greatly appreciate it.
