So I googled it and it says to go by the mah rating. So I have a 4200 mah so I can go has high as 4.2 amps right?


You will be good with 4.2 amps = 1C charge on a 4200mah lipo.

At 1C charge it will take 1 hour (in a perfect world) to charge a Lipo from 3.2 volts (empty) to 4.2 volts (full). Battery temp and balance will play in to your charge times. Some manufactures advertise 2C+ charge and will give you a faster charge time. 2C (8.4 amps on a 4200mah bat) would give you a 30 min charge time from empty to full. Stick to 1C and your batteries will last along time (a-lot of charge cycles). You should refer to the battery manufacturer web page for specifics on charging your battery.

6S for regular driving offroad 'eh? Vision & KeithM... you are both certifiable nutbars. I'll need to get used to 5S before I even think about 6S on a track!

Finally got some proper tires for the Vorza. Picked up some nip Proline Crimefighter M2's premounted from a guy in the for sale forum.

There are slightly taller and wider than the stock rims and tires, and have much more dense foam. These are going to make a huge improvement in the handling.





Sorry for the blurry photo...




And here is a photo of my mud guards that were made out of a MX goggle lens. They are holding up perfectly, although dirty in this photo.

Default Proline INSIDE JOB

Bought some Proline Inside Job tires, not too bad but I wouldn't say they last too long on the Vorza.



2 Lipos worth of laps on my local clay circuit (One 4S and one 5S) and they are now essentially slicks.

Why is this battery so cheap? What am I missing. Need a new set and looking for a good deal. Will this battery explode on impact or something?

Lol, no

I bought my 6S from Hobbyking for 69$, and it's great. That one you linked is probably good too.

Has anyone tried plugging their battery it into one of the ESC connections without a jumper harness (plugs into both ESC connections)?

You have to close the circuit.You cant leave one connection open.You need a jumper if no harness at least.

I just got done changing out my rear dogbones for vorza front cva's I won off ebay.So far no difference I can see.Maybe a little quieter because less play than dogbones.Also I bought badland xtr wheels and they are so much better than stock.

Just a work of advice. Don't run those Dynamite road tires with 6S. LOL The rubber won't stay connected to the wheels. Should have known better when I saw the fronts ballooning.

Caught it in time that I could re-glue them, but don't know if the repair job will hold.

Also, check the front CVD's. Had a pin start to back out. Also caught that in time thankfully.

Forgot to mention that the fan in my ESC stopped working. It no longer spins up during the power-on cycle, and it was reading 160-170 degrees with my temp gun and no fan turning.

I emailed HPI and they are sending me an RMA to send it in for inspection/repair/replacement.

Luckily, I have another CC system that I can run while the stock unit is at HPI.

Woa, this thread sure did slow down all of a sudden.

I wanna ask about diff fluid if any of you are still looking...

I changed mine this weekend. When 5 front, 7 middle, 3 rear. I noticed that my on power steering was reduced quite a bit and my front tires were unloading and ballooning. This was especially noticable on the street.

I read that thicker fluid in the middle will give a more all-wheel drive feel, increase on power steering, and help prevent the tires from ballooning. The fluild that was in the middle stock was definately thicker than 7,000.

Would you guys recommend increasing the middle to 10,000 weight? What about the front, leave it alone or go up to 7,000 as well.

That is the only crap thing about this speedy. My fan lasted about 20 minutes till a little rock blocked it and burnt it out. I cut the case open so it could breathe as well as sealing it. I left the fan wires exposed in case I want to put one on but the heat sink hasn't gone above 70 degrees even in summertime australia so I don't think a fan is needed.
