First off i would like to say i like my .24 alot. BUT saturday while leading the a-main in my states series race, the main bearing came apart and a piece of it got stuck between my rod and crank case and locked down the motor. Has anyone else had this problem? what size is the bearing? :confused:

Fully modded .24 has been the bomb for me.:nod: and pre-run is the race prep you still need to brake it in it will come with instructions. Stick with trinity 30% fuel. I keep hearing about problems with people using other brands of fuel. IMHO You should be able to get one in a couple weeks.

I just installed one on my FM .21 w/ 6.5 insert.

It tuned out nicely, still has great top end.
We'll see what kind of economy it gets this weekend.:sneaky:

anybody have the epoxy come out of the crank in to the crankcase on theirs? It just happened to me this weekend. Didn't do any damage cause it's like a soft silicone, but it plugged up my ports. Not sure if I can just clean it out and put it back together without the snot in there or is it a necessity for efficient operation?

Greg was that a fully modded? if so its part of the mod it helps out to flow better. I've heard a few that have had the same thing happen as long as you have nothing damaged you can re-fill it with devcon or JB weld in place. Make sure you clean it real good before hand.

Another great weekend for the Trinity ExTech2 powered losi. We had 29 entries in the buggy class, and my ExTech never missed a beat. Ran the 30min A with only two stops:D, sure helped out with my 3rd place finish. Had a bad start getting booted off the track off the back side and crossed the line dead last almost a lap down after lap one. Put my head down and drove hard, lots of power and smooth as silk to boot!! Worked up to 2nd place but made a few bobbles late hat knocked me back to 3rd, GREAT motor Trinity!!:nod:

It's not the full mod, just the pre-run race tuned model(extech 2). Should I still refill it with the JB weld?

Make sure it's really clean no oil residue and try to duplicate what was there and give it ample time to cure. You can leave it out it will run I don't know what you will lose performance wise. That's what Chad said.

I am looking forward to next week and Trinity / Epic opening it's doors for business again.

I expect Chad will provide the same excellent customer service as he has in the past.

Anyone know if the Ex-Tech Line will continue???

I talked to Chad today and he is back to breaking in motors this week, and I think the phone line will be up some time this week also. Look on the Epic site for the phone number this week.
