Ran my fully modded Extech .21 today even though I did not plan on it. My other motor I was trying had something go bad in it so had to throw the new extech in. I know they are ran a little before we get them so I only got to run a half tank before my B-main. Running at 185 and rich as hell I bumped and had the fastest lap times from any truggy out there all day! Ran the A still really rich and had 1.5 laps on the field but had a cvd pin fail. Replaced that and got out back out there 10 laps down on a 30 minute main and ran down the others and finished 4th. Motor was 205 and still really rich but still FAST! Cannot wait till its fully broken in!
