Thanks. I dont have an official topspeed yet- everytime I try to buy a GPS unit on feebay I get out bid by a huge amount, but I estimate the top speed at about 30-35mph roughly.

At the moment I have ripped two of my 7 cell packs apart into individual cells, and im just about to order a soldering jig & battery bars etc so I can make them into side by side packs which fit the Gmaxx chassis much better.
I did a little test this morning and managed to get some solder to stick properly to a old spare cell, so I am confident I can do this properly & not ruin 2 perfectly good but cheap battery packs.

Have u tried lipo yet? When my g3r revo chassis comes in I am going to set up for drag racing I think I will use the Novak HV 6.5 with lipo.

[suicideneil]

Lipo is tempting, but the financial costs outway the benefits, especially since everything cost about twice as much in the UK as it does in the US or else where really. For what I use the truck for which is general bashing around a large flat park I dont need super powerful batteries or long run times; I just stock up on cheap Nimh packs and get the equivalent runtimes for alot less money. For you though, Lipo sounds like a sure bet as drag racing needs lots of power & punch on tap, and only lipo or A123 cells are upto task in that respect. That said, i would like some A123 cells one day, but only when the price comes down again- $100 for 10 cells in the US, but its about $140+ in the UK, so.....

What? That's when you need the most power

[luisranza]

No joke I looked into a123 packs the price is sick.

[suicideneil]

Yeah. The cheapest method is to buy Dewalt 36v cordless powertool batteries then open them up to get the 10 A123 cells inside- you can split them up to make two 5s packs which is perfect for RC purposes. But like I said, the dewalt batteries are very expensive in the UK, and shipping adds a load more to the price since they arent small/light items. Still, its early days for the Li-ion technology so hopefully we will see bright things in the future- just like how Lipo has developed in a short space of time.

[suicideneil]

I suppose you could look at it that way, but Im happy enough with about 10-15 minutes run time, plus it gives me a chance to let the motor cool down & review any camera footage before I do another run; that way I get to spend a good hour or two in the park enjoying my self.

1515 2.5d (1700kv), 5s2p 8000mah lipo's, wheelies at 2/3's of full speed, no cool down time needed and run for maybe 45min without changing packs. Come on Neil, you know you what that sort of setup 6s is good too.

i have seen pats emaxx go too. apparently he can do a full race meet on one charge.

[suicideneil]

Of-course I want that kinda setup; I think I know enough now to be able to setup the Gmaxx correctly and choose the right parts to be able to do it. The only trouble is I dont want to sell my kidneys to be able to afford it.... All in good time, all in good time....

[suicideneil]

So, thats the driveline upgraded with UE Ultralite cases & HB 1/8 hardend diffs. Just need to see what BL systems are coming around the corner in the next few months and I'll be finished building the ultimate Gmaxx (in the UK)....

[ClodMaxx]

wow - looks even tougher than before (which i didn't think was possible! )

it's definitely worth of something much more powerful than that novak.

good stuff neil!

[suicideneil]

Thankyou kindly. Yep, it really is crying out for something more beasty than the Novak, 2 Novaks?.... na, I will wait and see what the new Novak system looks like- would rather have a sensored system so that its idiot proof, but I also want more power/torque for higher gearing and more sanity defying speed!

[neweuser]

Looking good man! Still love those tires!

[The*rc*dude]

WOW! It look's real nice! if only i could get my e-maxx like that in less than 3 years! lol
