My e-revo brushless edition build

[shaunjohnson]

you must race hard...or maby it's the E-revo's motor mount setup, i'm just using the little old 3mm blue motor mount that comes with the E-maxx trannies (single motor conversion of coarse)
and it's not bent

[mistercrash]

Are you using the plate that places the motor up in the center over the tranny instead of the ERBE's plate that place the motor to the side of the tranny? I have seen a few conversions that have the motor centered over the tranny. The way the ERBE is set up, the motor plate is secured to the tranny with 4 screws that are all on the left portion of the plate. The right portion houses the motor and is just floating with no support. With the weight of the motor hanging on it.

Bummer. You can really see how much material has been ground away on the closeup shots of the outputs, quite nasty.

yep that's what i have.
it must be absolutly rubbish for COG but i got used to it and cant feel much difference between my convert and a proper ERBE.

but my plate has not bent

Well if that's your truck in your avatar, I would say we have very similar racing styles So I don't know what made my motor plates bend like that.

Running my ERBE in the last few days, I noticed that it was easier to roll it over when making tight turns. I checked my sway bar set up and the front Tekno sway bar I run (Tekno front/Traxxas rear) has become so soft that it is now useless. Many don't beleive that the Tekno sway bars are prone to premature metal fatigue because they are too short and small. Here's a good proof. Longer and thicker sway bars don't have to bend as much and last longer. I replaced this Tekno sway bar with one I made. It is a bit thicker and taller so it will last longer. The same is installed on my nitro Revo and has been bash and race tested for over a year.



This is the Tekno sway bar I was using. The ends were bent upwards. Whether the ends are bent upwards or left stock, I experienced the same kind of premature metal fatigue.



This is the sway bar I made out of 2.3 mm piano wire. This same sway bar has been working awsome on my nitro Revo.

Hey gang...

I wanted to go back to your discussion about battery connectors. I have done a lot of work in the car audio industry on power delivery in high-current applications. You would be very surprised at how limiting wire and connections can be.

I started off using Anderson connectors, but after some research on them for an OEM audio system project I am doing at work, found out they are only rated for 30 Amps of current at 65*C... Given that voltage is speed, I switched to Deans based on their reputation. I like the concept that there is good surface area and a solid connection.

The EC3 connectors look to me like a set of bullet connectors in a custom housing. I like the idea of the bullet connectors from Hobby City, but unless you can really feel how tight the connections are, it's hard to tell how well they will work.

I have been intending to contact one of the RC car magazines and offer to do a connector test to determine ultimately who offers the best connector - but I doubt any of them would go for it, since they would be bound to loose advertising from the 'not winning' companies..

Anyways, use the most solid connectors your can, we are drawing a LOT of current through already undersized wiring - the slightest increase in resistance from a connector can definitely reduce performance.

BTW mistercrash.. I still want to get out and see that beast run!

Any testing you might do on connectors could be posted right here in this forum if the RC magazines are not interested. There would be a lot of interest in connector testing I suspect and what the final results would be. If you want to see my truck run, I will be at Hardcore RC race track Sunday the 26th to race in the club series race #4. Look for Raymond But no laughing at my driving ability

I sent an email to Derek at Xtreme... we'll see what they say.

I don't laugh at anyones driving.. it's all likely better than mine!

Someone PMed me saying that the template for the mud flaps can't be seen on my Photobucket account so I'm sorry for the large pic, I am posting it directly in here in hopes that it can be seen and downloaded.

i cant see the pic

mistercrash.. email me the pic and I'll host it for you...

Weather permitting, my son and I will try and get out to hardcore for a quick visit.

BTW, if you are (or anyone else) is planning on ordering anything from hobby city, I'd like to get some new Lipo batteries.. maybe we can share some of the shipping costs..

[mistercrash]

Can anyone see the pic now?

Dave, I have a lot of lipos that I am running right now, for now I don't wish to order anymore although these new ones from Zippy are tempting.

pic still no worky

If you want to sell some old ones to try some new ones, let me know.. I just need a pair that will work with my e-revo.. my 4000mAh NiMHs just don't have the balls...
