Zeppin Racing 12TZ3 Dark Force Ceramic Sneak Preview
 

Just saw this...

http://rc-mushroom.com/product_info....ducts_id=10549

That motor looks real nice ......wonder what they are gonna cost. :nod:

It looks awesome. I think it will be at least in the range of OS speed tuned. After all, it is hand mod and with ceramic bearing.

I like the sleeve, it looks better than the OS Speed. Not to mention the ceramic ball bearings!
Anyone notice the 3 little ports on the button & headsink....?? :weird: look like some heat release chamber to me.

Yup, just like the M-Speed motors from Japan. This guy does really nice work.

what does that scoop in the bottom of the head buton do ?


never seen that before..

It directs the flow of fuel/o2 directly to the glow plug.

looks interesting that scoop i might try it to one of my engines ..

does it matter which way it points ??

Hey jamie dont forget to look me up at the Glc

Robert

lookin for results of this motor any info :D

cost $325 from rc mushroom

I guess price went up $335 now :cry:

Yeeeeeeeeeha. Should be one of these showing up on my doorstep soon enough.

Cant wait to break it in and try it out!


Cheers,

its nice its still an os,i have motors like this,fast but dont last long at all.

That's a bold statement to make. I've used an OS TZ Eb mods for multiple races in the 90+ degree weather and instead of getting weaker its getting stronger. I believe that engine break in, care and tuning play a major role of how long an engine lasts. I take the entire engine apart after every race and clean out all the carbon deposits and any other deposits that may be left behind from a race.

These concepts (care and whatnot) are the same for every other aspect in racing.

Cheers,

what i ment was they dont last as long as others,i do like os motors tho

I disagree.....I see the .12 tz lasting just as long if not longer than other motors on the market.....very durable great starter motor. ;)

crank looks great. hmm, although its an OS, and theyre known for their runtime, modifying a motor can reduce the runtime.

does anyone even have one of these? feedback on the engine please! :)

I have to disagree with your statement as well. I have run OS engines since the early 1990s and they last just a long as the top engines from Nova, Sirio, etc. I have a square, red-head 12cv that I bought new in the early 90s, ran almost 4 gallons on the nickel sleeve and piston in an offroad truck, after-run oiled and retired it for 5 yrs, put it in a newer RC10GT and ran dirt oval for another 2 gallons, retired it again and it is still kicking strong. Once I got a temp gun (which I did not have when I bought the engine), found out it had been running around 270F degrees on the original nickel-plated sleeve (which should have burned it out by now). All of this while changing fuels 4 times. It still has pop, fires up on the first bump, and runs strong today. So, I can testify that OS makes strong engines that last, if taken care of in the right way and broken in properly.

Oh, I do own an OS 12tz that runs strong, never been over 245F degrees, gets about 6 minutes per tank on the big track (with 250+ foot backstretch) and have not had any issues with it other than a blow plug or two. Two weeks ago, I ran it for over 90 minutes at my regionals (5 min qualifier, 30 min B-main, 45 min A-main, with another 20+ min of practice/warm-up time) with it coming off the track at a cool 217F degrees after the B-main and 223F after the A-main. I have spare Novarossi and Sirio engines that don't run like this and I have broken all of them in the same way.

Now thats what im taling about. It's good to see people realize the quailty OS puts in thier engines is up to par with the best. I feel that we can only expects better things to come from companies like OS.

Also, I find that the OS engines are capable of making strong power with lower contect nitro....I never had the need to run 25 or 30% with my tz ebmods or Zeppin.

Cheers

its good you guys are happy with them,i like mine its now not fast enuff and theres 5 of us that will say that,i do like the motor ,very easy to tune and run, im not saying its totaly slow,just not quite there,i do run it at fastcats some sundays (www.fastcats.ca)

There was one thing in my testimonial I forgot to mention: I put over 220 laps on my stock OS 12tz and it is still running strong.

Wally,
I running run the OS 12tz in my mtx3, Max Power 12s3 MF in my mtx4. I have a Mugen X12, Sirio Evo2, and a Pixy Black 12 as backup engines. Between the five, the OS runs the most effecient and I turn faster laps with it in my mtx3 than I did with the Mugen X12, Sirio Evo2, and Pixy Black when they were in that car. It even is faster than the Max Power that is in my mtx4. I just ran in the RC Pro Series race in my area and ran a qualifier the the mtx3 and another with the mtx4 respectively. The older car with stock engine turned two more laps in its qualifier over the newer car with the "faster, stonger" engine with all other things being equal.

I just wanted to let everyone know that I finally ran this motor at a local track and WOW....truly amazing engine. The person that does the modifications is a VERY knowledgeable person and surely knows what he's doing. Any person that knows 2 stroke nitro engines would agree in a second.

I didnt even crank it up...kept it 200 and lower and it already has tons more power and punch that my previous EB mods. I cant say enough good things about it...worksman ship is amazing.

Next week ill crank the motor up to a max of 230 and I know it will be blistering fast.


Cheers,

I also ran it this past weekend with similar results. Ran it on the edge of too rich and it still had good power and speed. I have an LL3 from the same guy and the power and revs are awesome. Had to tighten my 2speed 1 1/2 turns over a stock TZ5port. With the Zeppin TZ, the setting is the same so that means it has loads of torque. Can't wait to push it.

Awsome news. Glad to hear this.



Cheers,

well i just blowed up my tz real good like LOL this passed sat, maybe my next one will be good.may be ill get a ZEPPIN i know a guy that has one and it looks pritty good.

Still running a little rich and getting stronger. I'm really happy with the workmanship and power. I hear they're working on new stuff too. Can't wait to see what's next. Can't go wrong with the Zeppin!

Are you making the five minutes mark per tank??
How much fuel do you have left?

I make the 5min marker with mine and have a splash of fuel left, but I slapped a CD3 tank in my car and now can get close to 6 min :)


Cheers,

OS 18 is stout
 

I put an EB mod 18 tz in my pro mod dragster. This is a .21 class but I'm thinking the .21 has too much power for the weight so I went to an .18. I broke it in 3 10 minute periods just like the instructions said. Kinda worried me because I like to get a half gallon of fuel through an engine before I run it at the strip. It took 2nd place its first race. If I hadn't been hacked severely in the previous round I would have taken the win. The car started out at 2.41 seconds and by the end of the day had worked down to a 2.20 second ET at 58 mph for the 132 ft strip. No blown plugs running on 25% where the rest were running 55%. Took the motor apart as I always do after a race and there was no deposits or anything inside. Everything looked brand new. I didn't touch the needles all day only adjusted on the pipe length and clutch. It does the 6 ft in .347 seconds. Very comparable to my .21 powered rail. This motor has plenty of grunt and top end. I've been using Novarossi but I'm switching over to OS. Just bought a .12 TZ for my sprint car. Get some corrosion-x and use that for afterrun. You'll be amazed at how free it makes the crank bearings. Clean them up with B-12 chemtool to get all the gum out then spray with corrosion-x. Spin the crank before and after and you'll see the difference. Doesn't eat o-rings or do any damage. Their speed-x product is great for 1-way bearings. Its really for skateboard wheels but its the best 1-way lube I've found.

Just funnished the running in of my zeppin 3port tz.

Does any one know what the recommended running temp. is for this engin?

Running a little rich left me with more than a few drops left in the tank. Maybe about a 5:30 motor. This was on a wide open layout for our track. Motor never went over 220 after leaning it a little bit more. Top needle is a little below 2 turns out. Maybe about 1 11/12. Had to adjust my clutch between heats because it started to spin the tires coming out of the turns.

The engine is not available at rc-mushroom anymore.

Anyone kept pictures of the modified pieces that mushroom had displayed?

Yo las tengo, donde te las envio
