HI Fierlo - remember you can go through your local hobby shop and purchase it cheaper..

I will let u know on how many gallons. I have 2 through mine and it still gets stuck on the box.. lol

Good to see you in here Chad!! Great job last weekend!!


Colin

what is the stroke of your engine ?

Maxi, raced with a EB modded Ex Tech last night (Sponsored driver too) and will tell you this from what I saw of it , It has REtarded bottom ! VERY responsive engine for sure ! As for milage... well my 21 gallon 421B consistantly out distanced it and pulled it on the straights and through the sweeper .He was getting consistant 7 minute runs and I was getting over 8 with no worries of running out ;)BUT I am a lot smoother on the trigger and my track is one that reqires a lot of throttle to be fast! The local hot shoe took the ExTech for a rip and run'er out of fuel at the 6 minute mark LOL .
He might be fast but he DEFINATELY hard on fuel :lol::nod:
I was impressed by the engine's performance overall though ,for $429 (I think) for the modded version , this is a nice mill . Ran cool too.
If I could get 21 gallons from one I would DEFINTELY get one! But I need to purchase one first to find out LOL.

I think it may be a rebadged CL7B to be honest....which would match killer low end and little less top end

A few pics of the engine installed. Tonight is the maiden race.

Well, Just went out and fired it up for the first time. Fired right up
and runs like a raped ape already and it is still running rich!! Temped
at 190 and is blowing a lot of smoke. Loads up when idling, so there is
still a lot left in it.
I will let you know how it runs tonight.

sorry for being a bit off topic , but last year i purchased a trinity .28 , this engine ran great with good longevity , problem is now its a bit wore out and i noticed i cant get p/s or a rod thru the distributors ( horizon ) and there not listed on trinitys website . any info would be great thanks again ! - the extech looks good , might get one , but if i cant rebuild it next season it becomes an expensive paperweight ! :D

I would be surprised if Trinity and/or it's distributors don't still have parts for that engine.
I think that engine is the same as the Picco .28 so the parts will fit from that engine.

Colin

Look on nitrohouse.com for the p3 .28 p/s set. Amain might have them to.

thanks !

I just got home from the races tonight. All I can say is the ExTech engines are for real!!
We took TQ in both Expert Truggy (me) and Expert Buggy (Kinwald).
I was misinformed and got to the track just minutes before my first heat, so I had a total of 1 tank through my new engine before my first heat race. I TQ'ed both rounds of qualifying. Our heats are 7 minutes and with the stock needle settings, I had no problem finishing.
I took longer than I had anticipated rebuilding my clutch before the main and I didn't make the start, so I started a lap down. I worked my way up to 3rd by the end of the main. I leaned the bottom just a hair and I pitted at 8 minutes.
This engine has a ton of bottom end and is scary fast on the top end. I can't wait for it to break in.
Kinwald also won his main and went the whole 10 minute main without pitting. I looked in his tank at the end and he still had almost 1/4 of a tank left!!! He could have gone 13 minutes or more.
Oh by the way......Brian Kinwald is back!!!!! :)

;)

I was pulling wheelies last night for the first time as well!!


Colin

That was because you were hitting ruts. Not because of the engine. FYI I TQed last night, not Brian.
