ImmersionRC vortex 250 pro, Instruction Manual

Q. How do I calibrate my 250 Pro ESCs?
DO NOT CALIBRATE THEM!. ImmersionRC ESCs use quality components with accurate timing
and never require calibration!.
Q. Can I fly in the rain?
ImmersionRC is one of the only companies in the racing quad business which conformally
coats key PCBs to add a level of water-resistance. This avoids problems when flying in very
humid areas, occasional crashes in wet grass, and the occasional use of the front of the quad
as a snow-shovel.
That said, not all components like getting soaked, the R/C Rx for example, or the sensitive
video transmitter module. For this reason, flying in the rain (which isn’t much fun anyway) is
not really recommended.
Q. I dunked my 250 Pro in the ocean/lake/pond, what do I do?
First thing to do (especially where highly corrosive salt water is involved) is to rinse the entire
quad in distilled water (available where car parts are sold, used to refill car batteries).
This rinsing process will remove potentially conductive salts from the water, and will ensure
that they don’t remain after drying.
Once the quad is rinsed, place it in a zip-lock bag filled with rice, and leave it in a warm place
for at least 48 hours. The rice will absorb the remaining water, and increase the chances of
life for your quad after the dunk.
Q. Do I really need to de‐solder wires to install a pimp kit?
Yes and no
…
Early shipments of the 250 Pro included a plastic design for the ESC covers
which passed the wires through the hole in the ESC cover. These did require de-soldering of
the power wires to replace the covers.
Later models, and many of the colored pimp-kits currently being sold, have a slightly different
design, where the wires are passed through slots, and don’t require de-soldering to replace
them.
