It was a hard decision

[jnev]

It was a hard choice, but I finally decided to not buy the CRT.5 and just finish the original project I started... the buggy (Xterminator). I just need to ask a few final questions before I sell my unneeded parts, old charger, batteries, etc and buy my new needed parts.

1) First, I was wondering what the difference between the 5mm bore 32 pitch pinion gear and the 5mm bore mod1 pitch pinion gear. I was planning on getting one of them as an 18t gear, but then I realized that the mod1 pinion is $18 and the 32 pitch one is $12. What is the difference between them and which is recommended for me? I am running a 46t kyosho spur by the way if that helps.

2) I am a little unsure about two of the Max Amps batteries. I was originally going to get the 4s2p 8000 pack, but the price went up from before. And now I am looking at the 10,000 4s pack and the price is way less than the 8000 pack... I'm still learning about lipo batteries so if you can help that would be great. Here are the two link to both batteries:

I also saw the 8400 and 9000 packs, but have never see anyone use them. If you can recommend me one of these 4 packs, that would be great. I am just looking for very long run time...

BTW - I will be running the MM esc and an 8xl motor with the rc-monster heatsink with a ubec on 4s lipo.

Thanks.
