RE: To B(ec) or Not to B(ec)
You can special order the Castle controller without the heatsink which saves a lot of weight.
It runs so cool you really don't need the heatsink. This summer I flew at a contest with Chip
Hyde and Todd Blose who were running the Castle HV85 with no heatsink and they had no
problems in the south Texas 105 deg summer heat.
