ragman i have that blue book too its actually a recommended reading material by vw of america and m.benz to their techs! so if i give any info here on this stuff its because i reaserched it or know from first hand experiance!
i guess a few of us have that little blue book huh, i like the chapter were they explain structural strengths in materials.
makes you wonder about the claims some of the r/c manufactures make on their cheep products! well thats another subject.
its nice to see that someone can agree with me that there is no need for a flywheel and that it is a tuning aid for drivability! i didnt even have to look it up!
thanks sandman!
