Speed Passion Reventon-R Problems
 

Please could anyone give me some advice as I’ve been having a few issues with my new SP Reventon R ESC and SP V3 7.5t motor set-up.

I installed this into my Cougar SV using the kit standard spur gear and 23t pinion. I’ve run the car indoors for 3 week at my local club with no issues and was really impressed with its performance :thumbsup:. However, 2 weeks ago I ran at the east mid regional’s (West Bridgford) and in the first heat after two rounds of practice, the car stopped. My first thought was the thermal protection had cut in because it was a hot day. I checked the temperatures ESC = 56◦C and Motor 62◦C, all in normal parameters. In round two, the car seemed great until the last lap, where the car, didn’t stop but acted like the lipo was flat. Again, I took the car off the track, check the temperature and lipo battery (SP 6200mah 65c 2 month old) all was fine, I switched the ESC on and off and the car burst into life again. To try in fix the problem, I re-binded the receiver and ESC to the radio. This seemed to work and raced the rest of the day problem free.

After a frustrating day, I thought it might be worth updating the firmware to see if that would solve the glitch. After hours of messing about, it was done. I ran the car last night at my local club and for an hour of hard practice the car was faultless. However, again in round 1 the car started to glitch, but this time, when I released the throttle the car would surge forward on its own. (For INFO I have a power cap fitted). Again, I re-binded and all was well.

This is start to really grind my gears and I’m not sure what else to do apart from return the ESC to the shop, but this will mean I will be without a car for about a month and I think it would be impossible to diagnose.

Any ideas?

Same Problem
 

Have you had any luck with this?? I have the exact same problem!

My mate runs the same and his runs perfectly fine!

Are you running lipo cut off. It my be as you are accelerating the lipo may be briefly dropping below your settings. Thus sending the ecs into sensorless mode, ie like the lipo is flat.

Might be a worth an email or call to Schumacher if its a common problem. They will be able to help

I spoke to schumacher and speed passion and both have said its a faulty motor no doubts!

I have sent mine for repair today so fingers crossed it solves the problem.

With what motor did you have this problem?

Speed Passion v3 6.5t.

Keep us updated when you hear back - would be really useful to know if that cures the prob.

Good luck

Seems that there is only a problem with motors like a 6.5 or lower.

I did some testing with mine and I only had problems with my LRP X20 6.5.
With the SP 7,5 and 8,5 everything is fine.

Yeah My mates got the same set up but with a 7.5 and no issues.

Should of chucked my motor in his car before sending it off really.

I'm running SP 7.5 V3 and after I updated the firmware for the 2nd time I've not had a problem (touch wood). Also for info, I have the Lipo protection turn off.

When I contacted Schumacher they gave me no advice other than return it and we with take a look :thumbdown:.

I'll keep you updated

This could be another problem then! I have updated my firmware but my friend hasnt!

I did not run mine before though so cant say for sure that it is that.

I will see what they say when my motor comes back.

The reventon R also only has an output of 70amp.
This combined with a Savox servo could also have something to do with it.
Maybe this is also an issue when going for a 6.5 or lower??

Just got off the phone to JE Spares and schumacher have tested my motor with no issues found! So next step is to rule out the savox! I have also bought a power cap to see if that helps. I will keep you updated.

Ok, So here is the results!

Motor back after being tested as 100% fine! Put it back in the cougar along with the glitch buster and it still cuts outs!

My next step is thermal cut off! Will it be safe to turn off??

Cheers

What about the LiPo cut off? If you only ever race for 5 mins or so, then take it off, that could be your problem...

I dont think it can be that! I checked the battery the moment it cut out and it had 3.85v per cell.

Cut off is on 3.2....

The battery is probably close to being dead at that Voltage as you are measuring it open circuit but not under load. Under load, a battery with low rating will probably dip to 6.4V with a low turn motor.

Unless you were sat in the car or had measuring equipment on board, you would not have been able to measure it when it actually happened. Maybe within 20-30 seconds, after you'd ran off the rostrum, took the body off, got a volt checker and then checked it...

Turn it off and see how it goes. Then you'll know for sure.

:)

When I wanted to get a Reventon R at Speedpassion Europe, Toni Rheinard did not want to sell me one due to the immense software problems and recommended getting the GT2.0Pro instead (which of course does not properly fit in my B-Max2). AFAIK the next big update is scheduled for early August, and I keep my fingers crossed that it will fix your problems and gives me the opportunity to get a glitch-free Rev R; the GM Recing Genius Sport 80R/120R also seem nice and small enough (very similar to or maybe even identical with the Vampire Racing ESCs).
In the meantime I'll speed up my Cirtix-controlled Yoke with a 9.5 Thunder Power motor, the 13.5R will be an upgrade for my son.

I had exactly the same problems with this esc.
Send it back a few days ago but no reply yet.

Ok, Let me know what they say. Will be good to get to the bottom of it!

Do you use a savox?

I've switched the savox for a futaba, changed motor, receiver, transponder. Everything! :woot:

I'm very curious how they going to solve this.

I am having issues with my revention S and a Savox servo. I never had issues using savox servos with other speed passion and Novak esc's I am going to run a load test on the revention esc to see if the 2A rating is for real. At this point I want to go back to a GT2.0 pro (smoked)...

Quick update. Turned off thermal cut off..... Ran last night for a good solid 30-35 mins and nothing! didnt glitch, cut out or anything!

so maybe the thermal cut out is set wrong? Hopefully an update will fix it. :thumbsup:

Just a suggestion...

TURN OFF THERMAL cutoff....thermal cutoff is a feature to protect ESC overheating, not preventing the MOTOR overheating. I have heard that alot of ppl saying this function is protecting the MOTOR from overheating, and that is NOT TRUE. I never use this function.

2nd..turn off LIPO CUTOFF.........I never use that function. If my lipo is charged, and it is good quality lipo, it never need that cutoff, if I am only using it for 5 minutes practice and 5-6 minutes of racing...I never have this function turned on.

These function are they because it is a liability issue....it need to be there. But if you are going for a real racing, turn them off...and race that 6 minutes and should NOT have any shut down or slow down issue...

Running the car for 30 minutes is pointless....tires are overheated, lipos is over used, motor is hot...car is horrible to drive after 7 minutes and driver should be tired standing for more then 7 minutes.

My 2 cents...

I don't know about Speed Passion but LRP SXX ESCs do monitor motor temperatures and cuts out if it gets too hot.

how are people getting on with there reventon r esc's now then ??

Ive used mine for the first time in my cat sx3 with novac ss 5.5t , ace ds 1015 servo , and to be tottaly honest im not pleased with it :cry:

I tried loading the 119mod software using my 2in1 lcd program box , and that wont work , soo then installed the stock01 software on it ..

had it on the same gearing /track , and the esc is getting really hot , also was playing about with the esc settings , to try and cool it down to no avail !!

and the other thing im dissapointed with, when going thro the esc setting using the led program card , some of the values are not revelant to the things your trying to change !! and as said above , would had been nice to be able to use the lcd box ( as you know what settings your changing ) and to upload to older software ...

soo very dissapoined :mad::cry: and will have to splash out for another esc ... rant over !! :)

I had this when i had a Reventon R, thermal cut-off came in really when it was barely warm.

However this ESC completely fried within three rounds of racing, running a 6.5 in a 22 with the Losi recommended gearing. PoS in my opinion, avoid. Replaced it with an LRP SXX TC spec V2 and havent had a problem in the months i've been running that.

cheers mate , im glad im not the only one !!:)

ive had an lpf for about 2 yrs , been used pretty much every weekend and still ok ( case is battered thou ) got an hw extreeme stock still ok ..

but i thought this would be good , very dissapointed !!

I've been reading the Speed Passion threads on the RCTech Forum !
There's a lot a chat about the S and R ESC's and the low BEC output.
It seems to be causing a few problems with high output servos like Savox.

Also I seem to remember reading about the LED card's values being mixed up, think it was values 4 and 5 were around the wrong way. The advice seems to be get the Reventon LCD Card as you can see what you are changing as it tell you on screen, the LED just shows the number !

Also seem to remember reading that 99% of drivers are turning off both the Lipo and Thermal cutoffs Off !!

Just put one in my son's X2C with a LRP 7.5T motor. He ran it last Saturday at Silverstone and loved it. He said it was very smooth and mental on the straight compared to his old Novak GTB. Motor and ESC were cool. This was using MOD1 software, zero timing and DDRS on 5. LED box worked fine for us although I agree the LCD box would be better. Maybe 5.5T motor is too close to the ESC's limit.

cheers for your help mate :) , one of the settings that was wrong was the thermal cut off , ( its meant to have 2 choices , and it went up to 9 !! ) , i had it on ( what i thought it was ) 95c and the lipo cut off was on 3.2v

is it only meant to be on the s and r's then ? ..

the only thing i remember , was my servo going really slow , when the esc got warm !! , now its cooled down its all working ok , just wish i could put the 119mod software on it , as that was what i was running on my old esc

Ok chap,
Think I may have read this right !
The Reventon R is a 70A ESC and rated down to 5.5 motor
But also read this !

Reventon R Stock 1 V18 firmware:
STO1 - for Hybrid Boost Technology ( for 7.5R to 10.5R Motorturn )


So if i'm reading this right, with the new V18-19 Firmware the motor limit is up't to a 7.5 Motor.

Think you cooked the esc chap !

Interesting - I've just installed one in my X4 TE, with a SP Ultra Sportsman V3 10.5T motor.

Even when holding the car in one hand, repeatedly blipping the throttle was enough to make the motor stop dead after a few seconds.

Out on the track, it lasted only a few seconds (less than half a lap) before cutting out. Turning off/on was enough to bring it back to life.

I tried changing the sensor lead with no luck, Then a friend lent me an old SP 10.5 of his own which I dropped in. No problems at all!

I've yet to contact the shop where I bought it but that's on cards first thing in the morning. I think I had a duff motor. I'll let you know what happens next.

no , dont think soo , i have a pdf on my computer , but cant upload it on here , but it says for stock01 , its targeted at 4.5 to 10.5t

Thats for the Reventon Pro ESC

Reventon Pro Stock 1 V18 firmware:
STO1 - for Hybrid Boost Technology ( for 4.5R to 10.5R Motorturn )

PDF for STO1 Reventon ESC - http://www.speedpassion.net/reventon...STOCK1_v19.pdf

yeah thats different to the one i have on my computer , but im trying to upload it
the one that i have definately says , its targeted at 4.5t-10.5t , using a "r" esc and its a worded document and not a set up sheet .....

Had a chap racing new reventon r at are track today have similar problems with his speed
like outlined in previous posts. Car was cuttin or lossing boost at random times and acelerating randomly. switching on and off fixed it for short periods of time but in the end it was a waste of time as.the issue would happen a min or two later again. This was in a touring car running a lrp 10.5 motor using stock 01. Think its a savox low profile serv0. The termal was off and the lipo cut off was turned off so I dont know if thats the fix for the issue. Shame because the car when it worked look very good but in the end his day was ruined with this issue cropping up.
