soo is it only problem on the "s" / "r" esc then , is the pro problem free ??

And going thro all the booklet they give you with the "r " none of it says 7.5-10.5t on the stock01 software ... it all says its targeted at 4.5-10.5t ..

I think this is the pdf you are talking about
http://www.speedpassion.net/uploadfi...structions.pdf


But I believe this is a global guide lines set out for the Stock1 Profile.
The limits of the ESC then must be applied, so if you are using:

The Reventon R the Profile is for 7.5-10.5 Motors
The Reventon Pro the Profile is for 4.5-10.5 Motors

yeah that pdf is the same as i have , and it also says that on my sp booklet , can't find anywhere where it says you cant use a 5.5t on stock software ...

I emailed schumacher , and they suggest turning the lipo cutoff and temp settings off and try that , and never said using that size motor is a problem with the boosted software ...

Ran again last night. Checked temps after every run. Motor was 65 and ESC 55 so no problems so far :D

OK, this is important.

The Reventon series is NOT related in any way to the GT series. It comes from a different factory and the accessories are NOT compatible.

If you treat a Reventon like a GT, you will have problems. Read the instructions, don't assume.

As far as the BEC goes - the output on the SCR, S and R is 2A, but it shouldn't be a problem with a well designed servo. Savox (and their OEM customers including Spektrum and Orion) are known to cause problems with their excessive power demands.

cheers for your help dave , but i'm using an ace servo , but ive been in touch with the shop i got it off , and they said try and turn the lipo and temp off , tried that and also geared it down even more , changed to the mod software, still no different , still runs hot even on a flat bit of tarmac !! put an old lpf in ( even thou a lpf is only meant to go down to 8.5t for off road ) to eliminate , lipos , motor etc and it was spot on !!

oh and " read the instructions , dont assume " have you read the little mixed up paper they include :eh?: , well thats why i had to search on the internet before it was fitted !!

Sorry chap but I think it's still youe 5.5 motor !
Borrow a 7.5 and try the Rev R again !

This way you can say its the ESC and this is what SP Say Stock1 on a Rev R is max'd out at !!

i appreciate your help , but as i said above ive tried it with the mod software and it still runs hot , but when you go thro the reventon interface thingy , and you have to mark what size motor you have , i did'nt see that using that software and that size motor there was any flashing lights , or anyone saying dont run it ..

and again the man at shuchmacher , did'nt say the motor size with the software was the problem ..
, but the shop i bought it off had said , that it could had been where it was close to the motor limit ..

I have had 2 r's been in tc, buggy and sc with mortors from 17.5t down to 7.5t and never missed a beat only had to turn off lipo as I have old ones with low c rating
As for the software I had to fiddle with the USB files at first with the first ones but new ones work no problem and the wifi unit works great

tried it today with an 8.5t motor and still getting pretty warm and still on the mod software , its now been sent back to the shop who i bought it from ...

but i'm geussing all the people on here that have had problems with them , are all at fault , and out of the 100's that have been sold , none could have anything wrong with em ??!! ..

Was just saying its a great esc smooth and fast
And u are going to get lots of ppl with faults writing on here
As its the problem page, if u want problems try a nosram/lrp esc
Or orca lol

i know mate , i'm just fed up with people on here, thinking that someones automaticly at fault if they've been ok with em ... they'res going to be a few slip throu the net !!

OK ! I must be one of those you mention !

But in my defence all I was trying to say is what is printed on the SP Tech Website

Again all I was trying to say was that although the SP Reventon R has a motor limit of a 5.5 motor, SP updated this to 7.5 with the new V1.8-1.9 Updates when using the Stock1 Profile.

If there is a fault then there's a fault, was just trying to help you eliminate issues due to over spec'ing the equipment.

You stated that the esc was getting to hot, a lower motor would cause a overheating issue

As you have sent this away for check's you will find out when it is returned !

Keep us all informed !

Is the reventon r working now? No more problems? Locking for a new esc to my sv2 and the reventon have a nice price.

+1 - I'm in the same boat (for the same vehicle coincidentally).

Are they on special now because it's a fire sale to get rid of a bad speedo or is it worth US$70?

How have people gone with them over the last month? Anybody running them in hot summer conditions at the moment?

I don't have one (I bought the pro and love it) but there are at least 2 at YORCC and both perform faultlessly.

Orderd one. Test on thursday.

Col im looking to put the Pro in my DB1 but have been put off by this thread, i take it the pro doesn't have these issues.

Cheers
Ross

No mate, from what I've heard these problems were exclusive to the R.
My pro is currently running whatever software came with it, and once I'd actually read the instructions and reversed throttle on my futaba TX, has performed brilliantly since.
It should be noted that (on mine) the stock setting for brakes was 30% which meant no brakes... When set at 100% it will lock up all wheels on any given surface.

Cheers fella your a star :thumbsup::thumbsup:

Did a test today. Verry good feeling. Soft and a good register. The punch is there when you need it. Verry satisfied so far.

I've had no issues with mine so far. Fingers crossed......

I have a SP Rventon R in an Xray t3.

I read through the instructions very carefully and discovered the "note 3" by the 5.5t

I've used it a lot since purchase in Jan with a 13.5t motor and it was fine but recently put a 5.5t motor in and it won't allow full throttle - it does a kind of emergency stop:(

With the car on a stand it does the same thing.. Fine until about 3/4 throttle then cuts then goes again. The orange light flashes too - suggesting esc temp.

This is with all protection turnd off.

Esc temps seem fine.. tested with 3 batteries.. no timing on ecu or motor... 13.5t runs fine :eh?: - can only guess it's not able to push the steady current required by the 5.5t motor..

I've tried all the different options through reventon software and think i have everything up to date..

I read through the instructions very carefully and discovered the "note 3" by the 5.5t rating. it says something about how they only test the motor limit under the following gconditions:

a) The input is a 6 cell Ni-xx battery; b) The ESC is equipped with a fan.


Any ideas??

hobbywing 120a v2 for £100 or reventon pro 140a for the same...??

Hey folks I am ready to blow my brains out..... I have a revention Pro running it previously on a 6.5 and now a 5.5 V3 the speedo was fine for about four weeks however now I am getting 3/4 of a heat and the speedo seems to be going into lamp mode (flat LiPo) I hav.e used other racers batteries to rule it out and it still happens, the setup is fitted to my dex410, my servo is a high speed alturn and the speedo is running the modify2 software.

It's been a very frustrating night as on a number of occasions I have been running quick in my heat

I don't believe I am running the thermal cut off but need to check.

When the car goes into limp mode if the marshal turns the speedo off and on again, its fine.... The motor and esc do not even feel hot.

For what I paid I am somewhat disappointed ! I tried to go on the sp site for help but it re directs me to schumacher


I am sick as a chip, can anyone help ?

Cheers

Richie

Did it do it again in the final after you down geared Richie?

Hi, I'm sure if you check on the website there was something about them changing the rating from 5.5 to 7.5. I reckon their first rating wasnt satisfactory.

I run mine In a 2wd buggy with 7.5 motor and have had no issues. Remember, it's only a 70amp speedo. If you want to run low wind motors you'll probably need to go to the pro version.

I would check the website first tho.

Dave

no I cannot get the 19t pinion to fit with the 87 spur (cannot get access to the motor bolts)


anyone able to help ?

We had this same problem with a Pro and a LRP X20 7.5 however our motor was getting very hot. Reduced timing from 22.5 to 11.25 and all was OK again. Didn't have this problem with a X12 7.5 with the same settings! I have read that this speedo and LRP motors don't play well together. Some are cutting the 2nd wire (don't know which one) to solve the shut down problem. Hope that helps

i think its 2nd from the left as you look at the motor should say few pages back also you can pull the terminal out of the plug dont cut it

also have you turned off your lipo cut off ? as it might be when its drawing large current the esc is askng to much of ur lipos ? this has happened to me alot on different esc

Yes you are right: - http://www.speedpassion.net/files/So...eventonPro.pdf

I have had these same issues with a Reventon pro, the car goes into limp mode after 4 mins due to overheat, tried changing the motor from a SP5.5 v3 to a 6.5 with no effect. Took a temp reading from motor and speedo as the car came off the track which were both under 65deg so no issue there. The capacitor on the speedo was around 100deg, changed this for the capacitor bank from a GT2.0 pro and the issue has disappeared (so far). The car now runs for full 5 mins and the capacitor unit was at 45deg. The only thing I cannot understand is how the speedo could sense this overheat on the cap?
I am running v20 firmware but may reinstall the v19 to see what happens
