4. BAG IT

[myRC]

Your filters won't filter much unless you lube 'em.

Stop neglecting your air filter. That, in and of itself, is a mighty good tip. But here's the real tip: use a Ziploc bag to lube the filters and store them. Put a dollop of filter goo in the bag and use it to saturate the filters without getting your fingers all sticky. Leave your spare filters in there so they'll be ready to go when you need 'em, protected all the while from toolbox debris. Go for the thick freezer-style bags; they last longer.
