Yes, the RCexl is definitely higher quality looking than the "blue". So, the concensus seems to be that I used too many cells on the RCexl and burned it.
For my blue box ignition, should I keep using 5-cell Nicd or should I switch to 4-cell?

The XYZ manual shows for ''blue box'': ''Input voltage: DC 6v. Voltage more than 7V will destroy the ignition. Larger than 10V will cause explosion.''
