The chances for that happening are sort of rare, so please look at other aspects also.
Unless you lost teeth in one of the two main gears, both blades should rotate at their designated speeds. It is more likely as issue with battery power, or possibly even blade pitch angles (which can be adjusted using the linkage at top end of the main blade holder). Here is an online copy of the manual for this heli (in case you don't have it). http://www.hobbyzone.com/documents/EFLH1200-manual.pdf Title: Re: Blade CX2 issue Post by: anwar on August 17, 2009, 10:37:01 PM Also, note that these coaxial helis have the two sets of blades rotating in opposite directions. So when you fixed the replacement blades (the top ones), make sure you aligned them for the right direction of rotation. The leading edge of the blades should be towards the direction of rotation.

(but you said the upper is slower) then give right or left Rudder and see the variation in the speed. You cab try the same with adjusting the Rudder Trim. You also might be able to set this on the receiver, there are 2 small parameters that can be altered to fix this. But please remember GO STEP BY STEP in eliminating the problem, do not touch the gain unless you are sure.
