Brushless Racing REVO buildup lotsa pics!
 

Well I've been racing my REVO for about a year now and always wanted to go brushless after seeing Tekno test their truck but I just didn't have the money or the knowledge to jump into it. Well I still don't have the money but I've learned a lot by reading up on lipo's, brushless motors and controllers, on this forum as well as others, magazines, etc. and decided it was time. Here is my REVO after a couple races ready to be stripped down.

And a basic idea of where the electronics are going to go
http://inlinethumb43.webshots.com/22...600x600Q85.jpg

From Mike I ordered a fiego 9xl and a xl motor clamp, that stuff is all here, need to take some shots of that . Also ordered 2 4s1p 5000mah packs from Truerc, spoke to Dan today, apparently a lot of stuff got ordered at the same time and they ran out so he's just now catching up, hopefully next week they'll be here.
What I still have left to order are my esc and bec. Will most likely go with MM and Casltes bec. Will probably get some fans too. Has anyone had any expierence with Venoms controller? It's rated at 120 amps and 6s lipo, and it's 135 at tower. Since I'll be using mechanical brakes I thought I might give it a try, any thoughts?
All suggestion are welcome and encouraged, I'd love to here any thoughts or ideas. Thanks for looking:smile:

It looks like an air esc so you will have issues - you'd need a posix (check spelling) converter to fix the voltage on the control.

MM with UBEC on 4s with 9XL is fine...

Well I couldn't find anything close to "posix" converter. What's wrong with the voltage? Just thought I might later go to a 5s or 6s setup and with this thing being so cheap, it was worth looking into.

It's not so much the voltage but rather how air radio systems work. Min throttle on an air radio is brake/reverse on a car radio. The posix (or whatever it is called) translates the signal from the receiver so the ESC is receiving the right signal from a car radio. You usually don't have brakes unless you use a servo.

Also, air ESCs don't seem to have the pulse or burst current rating that a car ESC does. Airplanes tend to have a higher average current draw with less bursts than a car. A car system usually has very high bursts with a quite small average current.

I think he meant "PiStix". It stands for "Pistol" and "Stick" since it adapts an airplane controller to be used with a pistol radio.

That thing is filthy. You must have had fun. I take it you don't have a misses. Mine would have killed me if I brought that into the house.

I think that thing is called a PiStix adapter. I am almost certain thats the name.

Edit: I had this page up for a couple hours already accidentally. The answer came just a little late. :lol:

:lol:I do actually. She knows how much I'm into R/C so she kinda lets me get away with it. Plus we live in a small studio without a garage, there's really no where else for me to wrench, all my stuff is either driving around with me in the back of my truck or in storage. I really am lucky she's so understanding:yes:

yea my gf is the same way. i make a mess at her house and shes ok with it.. im just stuck shopping for 4 hours the next day:rofl:

joker: it's funny that you said that because i can totally relate

Matthew, you might want to try a boat controller, as they are setup for a wheel radio, usually no brakes or reverse. The castle barracuda or hydra are nice, not sure if the aquacraft supervee esc will handle that motor, but it is good for 4s lipo. The hydra is the newer version of the barracuda and is good for 6s lipo, it has a cutoff too, IIRC.

Well it's all assembled, went with a Tekno setup as opposed to fabbing stuff myself. Pics will be up by tonight (hopefully) as well as descriptions of how it went. Will have feedback on driving as well as racing by Sunday, Saturday I'll be at Barona racing it and my messmaki.... err.. nitro 8ight.
Sorry to tease!

:lol:hurry up!!!:lol:

jk, hope it goes together well , let us know how well the clutch pinion thing works

Must of next day the tekno kit, mine wont be here til next week. Cant wait to see some of your pics.

Yep, I have a tekno kit coming too, the price was too good to pass up, plus I found a revo roller for 155 with a ton of spares. I still need to go thru it and makes sure it is in good shape! Will be interesting to see how well the clutch adapter thingy works! I am thinking of going with a 15l on 5s, or maybe aveox will get my 2000kv motor back to me in time. I have a quark 80 air esc to use as brakes are not a concern.

This link will explain alot about diff fluids and diffs.... enjoy

Wow, it was awesome, until I stripped a spur doing a wall ride :whistle:. I have the 3.3 chassis I got from Arct1k but no brace, and I had the slipper set maybe a little too tight to bash with (I race with it tight). My mesh may have been just a tad tight too, maybe. Also, it didn't switch gears, I think it was stuck in second. Well I'm going to replace that spur and I got a body to paint, but I'll post some pics first. My Mamba and TrueRC battery were both cool to touch but the fiego was getting hot already (only ran for about 5 min neighbor saw me do a wallride perfect then said I should do it some more, another neighbor comes out.... you get the idea). The clutch felt really good, smooth starts. Theres a little more deadband at the beginning of the throttle as opposed to a direct drive setup but I think it feels good. Something I was thinking about the clutch, it should lower the peak amp draw because it is easier to get the car moving. Anyway, any questions?

The elec clutch, you don't have to use an e-clip, a 3mm screw and washer work too

The motor mount, the slot is so you can get to the setscrew
http://inlinethumb19.webshots.com/25...600x600Q85.jpg

And something cool about the motor mount (If I mounted mine in the low position the motor would have just barely rubbed the rear arm, but that's because I am using the RC-Monster heatsink, the higher position fits fine, and it you run a neu there's no interference, I can't give up the extra cooling for lower cg)

So... How is it? Does it run well, any quirks?

Yeah ,it runs really well, great actually. The quirks I had were my fault, I was in a rush to assemble it and did not properly shim the clutch, it's fine now, and the slipper was a little tight, fixed that as well. Painting the body now, everything will be ready to race for tomorrow :mdr:

Looks great Matt - You racing Barona today? I was going to try to make it out today for the kick off of their Saturday points series. Too many new projects popping up due to the wind/firestorm. Hope to race with you soon.

that looks great.

whatd the teckno kit cost?

tekno revo conversion

its only 150 for the kit. not bad.

It was $129 if you preorderd it but now its full price since they started shipping this week

mmm i guess thats not too horrible.

saves you time from trying to figure out where to mount stuff.

Well I won my main in MT, lapped the other guys too. Hopefully there will be more racers next time, I like a bigger field, it's a lot more fun. 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.

hey just wondering how are the run times on it. thats the same set up im going to be running soon.

I should be able to get 15 min racing. We did a 10 min race, I ran 2 warmup laps (my average times were around 38 to 40 sec I think), a victory lap, and some donuts. I'll have to time it next time I run, I'll do a bash maybe tomorrow.

The E-Revo is looking great. Nice job on the 1st place finish as well.

I am sending you a PM right now by the way.

hey Matthew_Armeni
what type of battery is that and where did you get it like to know? love the conversion might use it on my revo still looking around for conversions. also would an hv maxx motor fit, don't know might be to long.

That is a TrueRC 4S1P 5000mah battery, you can go to Truerc.com and check out the packs, he offers many different setups. I mostly went with them because they were such a good value and I heard good things about them here.
If you're reffering to the Novak HV motors then no, they will not fit the Tekno conversion. The Elektri-clutch only works with motors that have a 5mm shaft, such as Neu, Fiego/Nemesis/Wanderer. The Novak has a 3.something shaft. If, however, it did have a bigger dia shaft, it would fit (you were thinking it might be too long, it wouldn't, I have a very long motor on mine plus the RC-Monster heatsink and it still fits).

You could try one of mike's bore adapters to up the novak shaft size to 5mm. Problem is that alot of people say that the novak shafts break easily and the weight of the clutchbell and flywheel will only make that worse. Best to stick to a motor with a 5mm shaft. Not sure why novak don't make a replacement rotor and bearings that have a 5mm shaft.

Actually, it might not. I thought they were breaking because of the "shocks and jarring" a direct drive translates to the motor, the clutch may help alleviate that because it is not always engaged. Maybe not though, just a thought:smile:
I heard a rumor that they were coming out with another HV system with 5mm motors? Anybody else hear this?

hey Matthew_Armeni
sorry for all dumb questions but where did you get the motor and esc looked on rc-monster didn't find it, where did you get and what did you pay. thanks for all the help

No question is dumb, always better to know or be sure:yes:
They are on RC-Monster, heres the controller and heres the motor.

right now they are out of stock on the 9xl motors. i emailed mike about it and he said it takes 4 weeks to get the motors in and he ordered them 4 weeks ago. so they should be in any time now.

Wow - I looked at that pack a while back and thought about getting one. I decided against it as the specs were a bit borderline and I didn't want to blow it up. True RC lists the 50A continuous and 75A max burst with "Field tested to 113A burst". I've Eagle tree'd my Revo set-up and it was right at the fringe. Looks like you've confirmed their specs. Do you have an Eagletree Matt? I'd be interested in seeing what your setup is doing. FWIW - I'm running a 3S 8000 Maxamps pack.

how are your speeds? Temps? runtimes? Weight? i have so many q's its aint even funny.:lol: ok maybe yea it is :lol:
