(...) You are wrong. The precedent, naturally, is C, coz NQC, isn't quite, err, C. Backslash _is_ the escaping character in C, even on Windoze.

According to that elementary physics, you are converting power into heat as part of this process. Usually, when downgearing an engine, the intention is to have more power at the slower speed (for better climbing, lifting, etc.). This will not be the (...)

I use an external battery pack whenever possible/practical. It has 8 (not 6) NiMh cells, providing a total of 9.6 volts. Works fine. Actually, it produces a little more power than ordinary batteries.
