Did You Know

Text Box: Balance the propeller It is extremely important to balance the propeller prior to installation of the engine. Failure to do so may cause  damage to the  engine and/or the airframe. Discard any propeller that is nicked, scratched, cracked or damaged in any way. Prop size and pitch are determined by the particular model and desired flying style, with the additional requirement that the maximum rpm should remain reasonable.

Out of trim ?

Did you know that MonoKote can cause your plane to be severely out of trim?  While trying to trim a club member's trainer, I could not get the thing to fly straight...there was a hard bank to the right.  Over the course of the day we tried everything--balance, servo movement, incidence, etc.  Nothing worked.  Finally, someone saw it...a raised trim piece of MonoKote on the right wing.  This naughty piece of covering looked fine on the ground but as soon as the plane was airborne, the wind raised the covering and the plane was almost uncontrollable.  Bottom line, be sure that all of your MonoKote or similar iron-on covering is secure--a loose piece of covering can ruin your plane's day

Prop Lingo
 

Say you have a propeller that measures 11x4 The first number  (11) indicates that the diameter of the propeller is 11 inches. The second number (4 in this case) indicates the theoretical forward translation the model would experience if the propeller were rotated one revolution. (4 inches). Again the forward translation is theoretical and is actually less in practice.
