Gotcha. Yea, I can see that. Thanks for the clarification. TLR and AE are WT based and while AE labels their bottles with CST close equivalents that's all they are.

I wish more (any) local hobby stores sold PTRC. I'd be a regular customer. However since I have to mail order everything anyway I ended up going with a non-PTRC brand but have been using mostly the same CSTs and have been happy. Cleaner, longer though? That seems attributable to shock rings and boots. But I digress - back to Tekno!

I like the PT Racing stuff, if I didn't have a bunch of AE diff oils here I would go with PT Racing stuff all across the board. Be nice if they offered the big bottles for the diff fluid too.

Hopefully they do another special for black friday.

It think it's the opposite. PT is one of the only companies that claims to have reliability from batch to batch due to full certification/testing.

PT RC Racing is one of the most accurate and consistent silicone oils in the radio control industry, trusted and race proven by many pro drivers at the highest level of rc racing. Each and every one of our viscosity numbers are carefully made and certified. We are dedicated to manufacturing, distributing and retailing of shock and differential oils for the Remote Control Car Racing Industry and enthusiast.

I agree, that's what I thought. PTRC is the company that got me wanting to shift from WT to CST (specifically using PTRC, based on the consistency and accuracy). I think what was confusing (to me) is the way it was worded by saying 'PTRC is thinner than most others'. I think more accurately is the other oils don't have accurate CST ratings, and are usually thicker than quoted.

Anyone use max wheelbase in the back? I run on a bumpy rutted track. May max out wheelbase in hopes of gaining stability and more steering. In theory it should help but everyone uses pretty much the standard 3/2 mm setup

I tried it, but found it was less stable. Especially exiting corners.

Wow I wouldn't of expected that.

I think that moving the wheels forward affects the dogbone angle helping with rough tracks. Also, moving the rear wheels forward will also allow more weight off the very back of the vehicle allowing for better traction. If you were only changing the wheelbase(by lengthen the chassis), then yes longer wheelbase might be better but when you only move the wheels it affects other aspects of the car.

That's exactly what I was thinking after I tried it.

What C battery should I aim for with 1/8th? In SCT I have 70c's, but 4s are way expensive hah, so what's a good range to go with?

Look into SMC batteries. They have very good packs that not expensive and perform very well. $70 for a 6500 60c battery. Lots of guys that are way faster than me run them so I figure they are good enough for me.
I don't think you need as high c rating when you go up in cell count. It is be beneficial to have really high c rating in low cell count, high stress applications like SCT but not as necessary with higher cell counts.
Hope this helps.

mkl's info is good. SMC and Promatch are brands I give a look for packs for a reasonable price. Promatch also offers a warranty on there packs as well.

For C rating I usually go 50C or above. But heck back in the old days when 1/8 E buggy first got started we were running helicopter motors with pretty high Kvs (3000kv or more were common to see people do on 4S) with 6000mah 20C backs and modified castle creations Mamba Max escs.

Ah the good ol days ...

Thanks guys, I'll go look for some 50-60c's. Wish I could just link my 2s together haha. But I'm excited to jump into the ebuggy scene finally. Just hate buying all new stuff, but that's part of the game. Lol.


I was getting my batts off eBay, but didn't really see good deals on 4s.but on SMC's site I see the 6500 4s 60c for $70. Awesome! Even their 2s are priced well on their site.. 6500 2s 60c for $37... Nice

yeah that have good prices and the packs do perform well. I usually do them or Promatch since they have a warranty and prices for some of there packs can be pretty close.

Promatchs 5200mah 4S I really like as its pretty light if thats your thing, though the Teknos balance better with the 6500s from what I am reading.

FYI you can link your 2s batteries together but it raises the cg of your car aND I wouldn't recommend it. Also the rule of thumb to determine minimum c rating is esc amp rating devided by battery capacity devided by 1000. Ex: 210 amps (peak amps on rx8) / 6000 mah / 1000 = 35c.
