Li-Po battery
I just fitted my Li-Po battery pack and voltage regulator to my car. The servo response is alot faster than my old 5-cell pack. I didn't put any of these packs on a scale, but the Li-Po battery pack and voltage regulator combined, feels lighter than my old battery pack. I’ve mounted them to my top CF plate. Still need to figure out a way to mount them to the bottom plate to lower CG.

What my current thinking was was to put the regulator under the pack and tape it to the CF panel similar to how you have done, but put the regulator UNDER the pack. Then use some 3mm ID standoffs and longer screws between the top deck and the CF panel to lower it towards the chassis.
I have tried to glue the packs to the chassis, the glue does not hold to the metal very successfully.
Thanks for the Pivot ball help I will try that.

Yeah im going to try and go with a lipo pack myself soon. Been trying to figure what size will work. I think im going to get the VXR ones.
For the pivot balls, I use clear nail polish to keep them from backing out. It isnt as stiff as CA and alows easier adjustment.
I have been using a LiPo in my R40 for about 6 months. I am using a 900mha and have made some miner mods to the original battery holder and got it to fit. I put some foam to keep it from bouncing around. I mounted my regulator to the side of the steering servo which I am using a Futaba 9550 low profile servo. I will try to get some pics up to show you

Hey guys....I've finally decided to just stick with one car (RRR). I guess I'll give you guys first dibbs on my car. It's a Hara edition, however, when I was building it, I used only the parts needed to convert to the Hara edition. Everything else is still in the package. I have tons of spares, such as carbon susp arms, gears, pinions, urethane belts, built diffs with 10k, 20k, and 30k diff fluid. It has the rear adj sway bar and I have some titanium pivot balls. If your're interested PM me or email @ [email protected]. I will post some pics later in the for sale forum. There is enough to build the 2004 edition and the 2005 (Hara) edition. I'm not in a rush to sell so no low ball offers. Serious people only. I just don't want it to sit around as I know that it's a capable car. It's just that my driving style is more suited for the Kyosho RRR. Thanks guys. It's been great rollin with the R40 for the past few years.

Jeff, what made you go back to the RRR besides your driving style? stock vs stock how did each car perform?
thanks Jason

Yup, and that too!!!
I too am most likely going to a V1RRR Evo when it is time to shift to a new car. It seems that HPI has pretty much abandoned racing the R40 with any of their team drivers, and no racing means no development work on setups and design.
I still have 6 months or so before my new one will need to come online, it will be interesting to see if anything happens before then.

But I also like to run a chassis that is being actively developed and improved on. So far HPI has delivered on that, the 2004 and 2005 models have all been a step up. But their commitment this year looks poor, and they are not fielding a team at the worlds as far as I can see. It seems unlikely we will see a 2006 edition.

Im going to wait it out and hope they come up with a 06 etc....I hope HPI is smart enough to not drop their pro car from the lineup. They have 20 different variants of monster-truck. Id hope what helped get them started will at least get some focus for a little.
But yeah I dont get this draw back from hpi. First no hpi challenge , now no team drivers. We havent seen a new setup sheet since what? 2003? HPI USA still never carried all the option parts for the car, Heck they just finally got the .8 2speed maintenance kit up. Which im very suprised it did finally arrive.
I dont care who does it , just as long as someone in HPI gives this new chassis some "proper" attention.
