If i were to do it again, i would not run the 2650.. i have 60% punch on close to the lowest timing (2-3). Battery efficiency is fine this way. Cant complain, Castle has some great stuff but my only wish it was sensored. (lets see what's next on their new software revision) On any either application other than a 4.3 (RC8/Ve8) internal this might be a different issue.

1400-1700 on 5/6S sensored would be the next choice, but for now the 2650 has been great every weekend for the past year or so.

I say if you just going in a parking lot the 2650 with be a good choice. 2200 is good all around motor for racing... Good power but not crazy power...

Thanks highvoltage, I'll be using it for fun runs after work to reduce stress and for hanging out with my 9 year old and his Stampede, so fun fast runs would be mostly what I'd want to do. I just want to have a really nice killer buggy so the 2650 may be the one for me.

How hot will this thing get or will it depend on the battery packs? What battery backs should I look at that won't create crazy amounts of heat buildup?

Heat is caused my many issues. The main one is gearing. To high of a gear ratio gives you tons of top end, but causes a strain on the lower end making heat. Also the same thing happens with to low of gearing, gives you tons of low end and Revs to much on the top end causing heat.

Buy yourself a temp gun and I like to keep my motors under 150 degree mark. But since you not on a track with tight turns the higher gear will not be as bad in the parking lot.

Battery size with also cause heat with the higher voltage going though them. But not as much as the wrong gearing for your driving conditions. Its hard to say what gearing is best for your driving conditions, just check the temps to be safe.

Thanks again, this is good stuff for me to remember. I put a DuraTrax FlashPoint in my Tower shopping cart. I'll do more research and decide what gearing I may want after I get my RC8Be built.

Appreciate your help.

here is the completed setup. I fixed my pinion problem by just buying the elite motor mount.


and here is all the electronics


and the new kustomrcgraphics body

Man, that is just Bad A$$. Which motor did you go with?

Curious, do you know how durable are the foam tires are vs. something like the Pro-Line Road Rage Street tires?

Gambitx, I think we have a similar missions here. I've been out of this hobby for a while now and just want a fast fun sweet buggy that I can do some runs with in a wide open college parking lot near my house. I'm also looking forward to spending time enjoying the building process. What better way is there to reduce stress after a hard days work than a few laps a high speeds with a beautiful buggy.

Your buggy look amazing.

I just got the Elite motor mount and the pinion and spur do not line up at all. I use AE pinions and only half of the pinion touches the spur. What pinions work with this motor mount?

short mod 1 pinions like Robinson

here is the list of mods and specs on my RC8BE

AE part numbers
25392 to replace the black heavy nuts
89082 to replace the heavy steel
89238 blue chasis braces
89239 blue chasis braces
89284 rear light weight stub axle
89285 front light weight stub axle
89286 aluminum gear box
89380 alum steering block
89381 alum rear hubs carrier
89109 44t spur gear
lunsford racing titanium screws and lower shock mounts
rcelite motor mount
hpi mod 1 25pinion
mamba monster 2200 setup and esc
AE ds1015 servo
futaba radio (cant remeber the model)
JConcepts illuzion body painted by customrc
boca bearings ultra yellow racing bearing kit
Ofna foam wheels

Ok i think thats it!
The build was just for kicks and to see how fast i can make it. So far i havent gotten a true speed, but it has to be over 80mph. I need a 3 lane road thats long and straight to fully open it up.
Also im using a 3700 6s 22.2v lipo for power right now, i am waiting for my reedy lipos to come in and see if there is a huge difference.

thank you Mulligan. I listed all my specs above. The foams so far are holding up with only 3 serious runs up and down the street. I would love to run a new pair only on asfault to see if there is a better hook up in traction because right now they do break loose still on the street.

Has anyone had any expierence with the RC Screwz screw kit for the rc8 or rc8e, I recieved mine today and I'm missing at least 17 screws and by the way it's going I'm sure there will be more as I am building my car piece by piece (not a kit) and don't have shocks, cvd's, rear arms, or my electric conversion kit yet. I plan on calling Monday but, I am wondering if this is common and how there customer service is?

Just a suggestion to everyone...Post pics as attachments so that they don't screw up the pages. We'll still look at them.
