Do you guys feel the plastic clutch bell and main drive pulley should be upgraded? Anyone had any issues with them? I remember something about having to glue the tail pulley or something??? Any thoughts?

I'm still running the stock clutch bell on both of mine with OS37's and never had an issue. You are right about JB Welding both tail belt pulleys to the shafts though.


Cop: Sir, have you been drinking? Driver: Why? Is there a fat girl in my backseat?

There is nothing wrong with the stock clutch or clutch bell. I've run three Caliber 30s, two of them almost since the Caliber 30 became available in the US, and have NEVER had a problem with the clutches.

The plastic clutch as well as the stock pulleys and gears are also more than adequate. If you start shearing teeth off the big main drive gear, it's time to replace your one-way clutch in the countershaft.

The pulleys that drive the tail rotor belt are plastic. The holes in the pulleys are "double-D" shaped, imagine a circle flattened on the top and bottom.

Over time, the flats tend to wear, and the holes can go round, causing you to lose TR control.

There are two solutions. One, spend something on the order of $40 to buy upgraded CNC aluminum pulley set (see Chris at RC Heliworks, he'll take care of you), or take the pulleys off the shaft (front and rear), clean everything well with alcohol to remove oil and grease, then use a small amount of JB Weld on the pulley bores and epoxy them to the shafts. Let cure a full 24 hours before flying, be sure not to let any seep into the pulley grooves. Again, after this fix, none of my TR pulleys has ever given me a problem. I've incorporated the JB Weld regimen into my Caliber 5 and Caliber 4 builds, as well.

That is very odd because I thought one of the best upgrade that I did to my caliber was the metal clutch. I had a problem with plastic shaving from the clutch get into the carb and killing the glow plug. After up grading, the problem was solved.

You most likely had something wrong with your original installation. Taking the assembly apart, then replacing a major component probably corrected the original assembly problem.

On My main problem was that I burned a gallon a week. After the second plastic clutch I decided to switch to metal and have not had a problem in two years of flying, also upgraded to OS50 with 600mm baldes and still running strong.
