Stating the Obvious...
(you could say silly, but I bet you've done some of these!)
Always
remember to switch on transmitter AND receiver before launching model.
Always
check that left aileron on the transmitter does actually equal left aileron
on the model.
Remember
to fit enough elastic bands to hold the wing down. Lapses in memory may result
in fuz going straight on if you attempt a fast loop.
Make
sure that the model about to be launched corresponds with the model held in
your computer transmitters memory.
Always
remember to put the transmitter in the car before setting out on a days flying.
Don't
stand on your wing when discussing your last flight in the pits.
Don't
admit to your wife/partner the real cost of that nice new model you just bought.
