I dont balance propse unless its going on - A 4 stroke or a high performance/high rpm racing engine.

When i do balance them i get them pretty close to perfect takes time but its not hard.

If there is anyone thats a bit confused on how to balance props take a look at this http://www.dodvideos.com/don3.wmv

INsted of adding to the back of the light prop you can sand the tip of the heavy prop
