Viper 15

Yes, it was doing it before you cut it.

Viper 15

Well I just put on the capasitors and no difference, possibly worse I couldn't really tell. I amgoing to talk to novak and see what we can come up with. Thanks for your help.

does it really void the warranty. how old is it?

Viper 15

I got it november 11th 2005. It says on the warrenty if you remove the stock tamyia and jst plugs it is voided.

I discovered something very interesting. I stuck a fresh battery in there and ran it. Same thing happened. I stuck a p2k with the rooster and it ran fine. I stuck my chameleon with my duratrax esc and it ran fine. It is the chameleon and rooster combination that gives me problems. Any suggestions?

kostaktinos_mt

wait wait... when you connect directly the chameleon with a battery, it still behaves erratically?

Viper 15

No just with the rooster esc. It works fine with any other esc and the rooster works fine with any other motor but the chameleon and rooster esc combo has the problem.

kostaktinos_mt

then its definately the capacitor! if you installed the new capacitors and it behaved worse than before, then you should try to remove the current capacitors and try capacitors with different capacitance as i said before [try 0.1uF,0.01uF and 1uf maybe]. BUT YOU NEED TO REMOVE THE STOCK ONES PRIOR TO INSTALLING THE NEW ONES! otherwise, you will most likely correct nothing.

XXT-CRer

im stumped, that is weird. what does it do exactly?

kostaktinos_mt

its exactly what we were saying yesterday: different ESCs work under different frequency, thus requiring different capacitors.

XXT-CRer

hey viper, see if the endbell from your p2k will fit the c2. if it does try that and see what happens. that is the only way to get rid of the caps on the c2. or you could try removing the 2 little capacitor grounding wires under the endbell screws and just see what happens.

Viper 15

When I push on the throttle it will just sit there for about a second and then go full throttle. I was wondering, could it still be the brushes working in. There are a few ridges left in the brushes. could that be the problem?

XXT-CRer

i really dont think so, it sounds more like current issues than radio interference.and if it did it before the rebuild, then that would rule out the new brushes. what if you give it just a little throttle? is it drivable at all? or does it just run away? does it stop when you let off?

kostaktinos_mt

no. if it was, the chameleon would react the same with the intellispeed esc.

kostaktinos_mt

i didn`t quite ment radio interference. i said esc interference due to harmonic pulse waves. its different. but it also could be the setup of the esc [unlikely,but...]. viper15, try to setup the esc once again -but with the chameleon connected.

XXT-CRer

hey kosta, could it just be lag, or delay maybe???/

kostaktinos_mt

XXT, that is what i was thinking about. a new esc setup [with the chameleon pluged in] could determine that.

Viper 15

Well I tried programming it earlier today without the chameleon, and I just tried it, it wont finish programming. It's like it locked up in the middle of it. Is there a certain amount of times you can reprogram it per day or something?

kostaktinos_mt

no there isn`t such a thing, BUT the deal here is that we just found that the problem is actually the esc and motor compatibility -as i expected it to be! try again with different sequences: disconnect the motor and program then connect the motor and try, try with the motor connected, then try connecting the motor during the programming process,etc. keep us posted.

XXT-CRer

dont know, ive never had one of those roosters. you might try disconnecting the power(remove the pack, and short across the power leads WITH OUT POWER ON IT, just touch them together for 5 secs or so, some microprocessers (sp?) reset when you do this, but make sure the pack is not hooked up.

kostaktinos_mt

i will agree with XXT. short both the input wires and the output ones [that go to the motor]. even if that won`t reset the microprocessor, it WILL empty any internal CMOS-suporting capacitors, which will help that rooster reset when powered on. {REMOVE ANY SHORT_WIRING BEFORE REHOOKING THE PACK!!!}

Viper 15

Do you mean to touch the battery(input) wires to the motor(output) wires? If so, it didn't work.

kostaktinos_mt

NO! use a wire to short the input leads [black to red], and another wire to short the output leads [again black to red]. JUST MAKE SURE YOUR ESC ISN`T CONNECTED TO ANYTHING ELSE WHILE YOU DO THAT!

XXT-CRer

no, touch the 2 wires that go to the pack together for a few seconds. the ones sticking out of the rooster that go to the batts. then touch the ones that go to the motor together for a few secs.

XXT-CRer

hey kostaktinos, its funny how we keep answering him at the same time. everytime it happens i start laughing, you must type faster than me cuz you beat me by bout 2 mins everytime, lol,xxt.

Viper 15

Okay, I just finished testing and the problem seems solved. I am going to test some more tomorrow to make sure. Thank you so much for all your help.

xxtcrer: now that it was working your cut job was really nice. Thanks
