Brushless Racing REVO buildup lotsa pics!

Are you using the mechanical break or do you use the breaking setting of the esc?

Hi and welcome to the forum.

The Tekno kit employs the use of mechanical brakes.

I know - i already own one of these .. i am waiting for my revo roller
I am gonna build it with a Feigao 8XL running on 4s Lipo and a hexTronik 120Amp controller.

My last problem -at the moment- is about wiring esc and the servo used for mechanical brakes

Ok - I didn't understand your original question. There are two ways to do it. The easiest is to plug a y connector onto the throttle port of the receiver. Plug the ESC into one ind of the y and the throttle/brake servo into the other. Be sure to disable reverse and braking on the controller. The other way will depend on your radio's capability. Some have the functionality for mixing channels. You can plug the throttle/brake servo into the third channel and use the radio programming to mix with the throttle channel and have them work together. You'll have to check you radio's manual to see if it has this feature.

Well currently I am mixing the third channel on my Hitec CRX with the throttle channel, this way the brake servo only moves in one direction. This is probably the best way to set it up. However, on my original setup I just used a y cable out of the throttle channel on the rx. Turn the brakes off on your esc and you can use the endpoint on your radio to adjust max throw on the brake servo (just as you would a nitro) because that setting won't effect the esc. Be sure the endpoint is maxxed out for the throttle, or positve endpoint, you only want to mess with the brake, or negative endpoint.
I hope I explained that well enough, if you have any more questions, please feel free to ask, and welcome to the forums

Wow, I type sloooooooow.., riceman beat me to the punch!

[mabu]

Oh ... i didn't think about mixing channels

i tried a setup now ... it is working well using a mx16-s

Thanks :)

Humm
I love brushless revo conversion !

it looks like the motor will hit the rear arm in hard landings? does it or is that just from the view i saw? does it hurt suspension travel?

It doesn't hit, although it is close. I'm running Mikes Motor heatsink clamp and that pushes the motor back a little further then if I weren't to run it but it still fits with no problems.

I temped my clutchbell, motor, ESC, and battery after each practice, qualfier, and main. 5 min quals, and 1 10 min main(after the main I did a bunch of donuts too). My highest temps of the day were
-Clutch-116
-Motor-166
-ESC-118
-Battery-121
Outside temps-the high was mid 70's but in the sun it felt like mid 80's.
I was running the RCM xl heatsink on the motor and a novak 25mm fan on the MM. Also, I started the day running 15/38 stuck in second because I stripped my 36 spur the previous night and 18/36 is just barely too tight to run (17/36 should be fine, as well as 18/34-haven't verified this though) but I wasn't fast enough on the straight and did not have enough pickup to clear all the doubles. I was able to get a 36 spur at the track so I threw that on and also went back to the 18 clutch for the second qualifier, bingo! I was now clearing all the jumps with ease and zooming down the straight. Also of note is that my temps stayed pretty consistent with the gearing change. In fact, the only change in temps (more the 10 degrees) was the battery after the main (due to the longer run time). The battery was around 101-110 during the 5 min quals.
I think I covered everything, so here's a few pics, also, a link to the tracks site.

What are you currently using?
Are you going electric from nitro, or starting from scratch?
Do you want to go BL, or just sticking with brushed electronics?
What voltage will you want to run/ how many cells/ what kind of batteries?
What is the weight of your rig?
Do you have any existing experience of electric/ BL?

Better to read the stickies and existing E-revo threads and do a little research, rather than just jumping onto a thread and saying "what am best motor?".....

i have a revo 3.3 and i am doing nitro to electric and i have seen do many BL motors out on the market and i do not know what to get and i am goign to use old 6 cell 3800 i have it first then go get a 3 or 4c max amps lipo

[suicideneil]

4cell lipo from somewhere other than maxamps would be best, depends on your budget though (4s = 4 cells, the 'C' stands for the packs amp rating EG: 5000mah 10c pack is able to put out 50amps in theory). Maxamps are good, good over-rate alot of their stuff.

Budget is your biggest issue to concider then before choosing your motor and esc, since there as several 4s lipo/12cell Nimh esc and suitable motors to choose from....
