You will be pushing it with those 4400's depending on track size. To me thr 2.0 rear just makes the car easier to drive faster.

Thanks mate.
Easier to drive always sounds good. Might just stick with the current batt's then, just to be safe. Worry about all the weight saving stuff if and when i get good enough to tell difference.

just finished my 811be2.0 build but see there are nowhere for the receiver wires to go into the receiver box manual doesn't say anything either..where has everyone else put them through? pics?

There should be a little slot/port in the receiver box between the lid and the box on the ESC side. That is where the wires go through. I could not get all of my wires into the box without leaving the lid unscrewed some.

Anyone having problems with diff gears

That's not a normal issue. What is wrong?

Never have had problems with diff gears. Whats up? ring and pinion or internal diff gears? Do you have the shimmed V1 gears or the newer non-shimmed gears?

Has anyone had a chance to run the new 2.1 yet? I am looking to replace my worn out 1.0 with the 2.1 so I am curios to hear opinions of it. Also, does anyone know when the 2.1 will be available?

Built and Ran the new 2.1 last week. Build was spot on as usual with some new cool features I was very happy with. At the track topped it all off. I am a on road nitro guy so this was a bit out of my element lol. However the buggy was so hooked up I was able to take TQ with a lap on the field. I finished 3rd in the main because I forgot to tuck my switch away lol. Hit a big jump landed then the car just coasted to the pipe. Oh well for the first time out the car was awesome! Everything went together well and raced even better. I just may keep at this dirt thing :tire: :tire:

Battery "c" rating

The last set of batteries I blew up because I didn't calibrate my esc or set the LVC:mad:. Completely my fault rushing everything. What's a good c rating to use for two 2s batteries in my 1/8 buggy.

Here's my setup:
Serpent 811 be
Tekin RX8 gen 1
Tenshock x812 1900 kv
Protek 150 s
Battery ?

Could I use two of these batteries in my buggy and not worry about blowing them up with excess current draw?

Any sugestions on other batteries to use in this buggy and what c rating? I just need a pair of batteries that will give me 12+ min of run time, have 4mm bullet holes, are relatively cheap, and are hard case.

Let me know what you guys think,
Thanks

I personally use smc 7200 mah. I will have to check but I believe they are 60 or 65c. I don't get caught up in all the C rating hype

The 6500mah's will definitely be a good thing.

The heavier car might benefit you initially [if you are a new driver], then later if you want to shave some weight off and are able to adjust your set-up accordingly you should find faster laps.

I have run 2x race meets with 4100mah on medium loose track with lots of bad driving [wheel spin] 10mins and had plenty of capacity, my car weighs 3500gms rtr.
Next I would like to try the tekin t8i 1900 to try and tame the power and drop some more weight.

Make sure you check out plenty of recent set-up sheets for your build - it seems that these cars like to have fairly heavy diff oils.

Cheers.

Hi guy's, i know this isn't an RTR thread but hopefully you can help me out.
Buying the 811Be RTR as a starter to see if i like 1/8 offroad and don't want to spend a fortune on upgrading. Will splash out on a new kit later if i like it.

Was looking at the 2.0 basic upgrade kit, #600643. Will i notice a handling difference with just the wider rear 2.0 arms?

Also i currently have 6500mah SMC batteries which i use for 1/10 TC.
They weigh 612grams/2 packs, will shorties that weigh 418grams/2 packs make that much of a difference to handling?

Will the 4400mah batteries get through a 10min run and still have about 20% left? I am not a fan of running lipo's down to the limit.

Thanks in advance.

Thanks! I just need to know the bare minimum c rating I would need. Once I know that, I'll work up from there if my budget allows.

I run 2 Turnigy 6600 65C batteries, with my moderate esc settings (can't remember them off the top of my head) I can run any 10-12 minute main with battery to spare. I may not be one of the fast guys, but I survive my mains.

Yep just completed my 811 be2.0 non shimmed and my center internal gears just crunch and don't move the drives any ideas?
