did the first ExTech's that came out have a ceramic bearing?

thanks

i would have to say yes dan
mine has it but not sure if EB mods changed it out to one or they came that way

The cooling head broke off my Extech .21. Anyone know where I can get another or what other head will fit?

Thanks

I'm having a little trouble with the tune on my brothers extech .21 we just sealed the carb and backplate does anyone know what the factory settings for the needles are thanks for any help

My gasket from the pipe to the manifold is starting to go bad. Can I use any gastket or please give me some recommendations. Its not the gasket that comes off of the engine but the one that connects the pipes together.

1) our engines have always and still come with ceramic bearings

2) I have extra cooling heads in stock. This problem has been resolved with the new engines.

3) I am currently out of gaskets but Italy comes back to work on monday so our order will be on the way soon after then i will have them back in stock :)

4) the slop in the rod comes from when you put the flywheel on and push the crank against the back plate. then there is a little play which causes vibration and premature wear. Always pull the crank out when you install the flywheel, then you wont have any problems.

I will be on here more to help you guys out.. sorry I have been away for so long. :(

I was told by Trinity that the P3 is ok but not the right plug for the motor. They told me to run the P4. I have been running the P3 and it is good but I get a occasional flame out, maybe one every 40 minutes or so it would flame out or a bad plug. Called them and thats what they told me. Have no P4's yet and my P3 lasted this weekend good so who knows.

Welcome back Chad. :D

What are the bearing sizes for the Trinity Extech .21?

7x19x6 and 14.2x25.3 x 6

Glanced through search results of the 124 pages of this thread and did not find a definate answer to my questions.

Filling came out of my crank, are these being warrantied or are they still ok to run without it?

How much fuel needs to go through these before race tune can be had? I've put around 7 tanks through mine heatcycling but it doesn't even fell like the metal pinch has loosened.
I think I'll be running this in my D8T so how will it compare to my last RB C6 in runtime and grunt when it's fully ran in and tuned ? Or will I be better off putting it in my losi buggy and putting my picco in the truggy.
