Hi all. Well after pondering a while i thought I'd try and digital conversion myself. A few soldering burns later I have a great result after referring to the forums on here! However, now and again 1 of my 2 Fly trucks (MAN) does 2 things:

1. Sometimes loses it's ID or rather changes from 4 to 6
2. Sometimes keeps open full throttle despite trigger release (there have been a number of cosmetic casualties to the layout as a direct result of this!! - now restricted to 50% throttle)

Thanks in advance

Craig

Hi Craig,
I have chipped four FLY trucks and all have been fine using the F1 chip. What chip are you using?

Some things to try: keep your braids neat and tidy and watch out for the XLC and CLC crossovers. These points caused sparks as the braids brush over them and it's these that can cause nasty power spikes that disrupt the functioning of the chips. Rikorocket has a fix that involves masking off part of the rail just as it meets the plastic crossover part in the track.

Cheers - Greg

Hello

do you have a capacitor at the Flymotor? Still the capacitor at the braids? Or ferriteman!
If not solder it back.

best regards Reiner

Hi.. F1 chip, with the capacitor at braid end... have I missed something important? And ferriteman?

The ferrite man is the capacitor + ferrite lump that connects to the small "feet" that sit under the guide to connect to the braids. After a couple of pints, it take on the appearance of a man with green & yellows as the arms. It is usually already in place and is supposed to provide a degree of protection against interference on the digital signal.

Run your truck again and pay close attention to when it starts to go haywire; the F1 chip is normally pretty good.

We have had issues with F1 chips and Fly trucks all Sisu's some have been fine but 4 of them so far were having the problem of taking off at full speed after an xlc i even put incar pro firmware on 2 of them and did not stop the issue and we also had ferrite man on motor and guide and also checked and changed braids the only way i have managed to fix it is by running a saloon chip and now they are fine, but i also have f1 chips in 2 MAN's and a few Merc's and dont have any issue with them

Hi Craig

do you solder a capacitor to the flymotor? I have a friend with the problem too. After he soldred a capacitor to the Motor. No problems more.
Same failure he had for other cars. Capacitor help.

regards Reiner

QUOTE taking off at full speed after an xlc
The width of the braid can get quite broad and when this passes over the intersection of the track it shorts producing a flurry of sparks. Try running any vehicle in the dark and watch it produce a neat display after every XLC and CLC.

Rikorocket has demonstrated a fix for this and Scalextric have incorporated his work in the new XLC. If this fix does not fully fix the problem then try using a full ferrite man on the motor as well, certainly a capacitor as minimum.

Yeah not that either, i have a routed track with no metal rails in the crossover and the copper tape is cut short at the crossover to stop any cars braid from going straight though the xlc touching the tape from the crossover and i had riko's fix on the xlc's when i had a plastic track. We also have tried a heavier spring on the guide to help get better contact

Right so definitely have sparks going across and xlc... no more time this week to investigate. I have the piece of ferrite that comes with the chip itself, and this is on the capacitor on the green/yellow wires heading from the chip to the braids... with std fly braids.

And I clearly don't have a wide enough track for 2 trucks racing together..... wow awesome!

Next stop on my soldering journey : 2 x aussie touring cars + 3 x slot it group c le mans racers...
