Just bought my buddy`s Ofna ultra comp 2 for $100.00 ! It has a.26 Force motor that`s wiped out...! He ran it way to lean and POOF..! Other then that it`s in great condition. Anyway I`m thinking of making this into a drag buggy any suggestion`s for a REAL screaming motor ? I don`t want to break the bank but I`m thinking of something around $200.00...

STS

Never seen this or heard anything about these motor`s...? Thank`s for the link.

That engine there is a beast. Total screamer, and tons of power.

What engine is that? is that the tiny one? .12?

STS .30, if you want one of those, email Ryan from Racer Nine, he is the nicest guy to work with.

wow .30, amazing, what are its specs:rpm/hp?

OMG, i saw one on ebay! its like 150 bux!!!!! should i consider buying it too for my custom 1/8 basher buggy that will hopefully do wheelies?

Just got done looking at the STS mod-ed motor`s ...sound`s good for $239.99

yo guys, how about this:
http://cgi.ebay.com/STS-30-PullStart...QQcmdZViewItem
seems much more affordable

Look`s good NWO....But the mod-ed version is $100.00 more...still seem`s like a great motor for what I`m doing ! Good job.

Thank`s

could you link the modded version, i would like to take a glance at the specs. Thanks

If you can find one go for the:

SH .28 Prospec 8 ports or the LRP Z.28R 8 ports from Team Associated.

Dang bro, well said
edit: thats exactly what i had in mind right after Novarossi 528

Above 46u has the site..! Scroll up ^^^^

The more I read about these motor`s the more I like.

oo, thats right, didnt think the modded version was on there

That`s what my bud said ...the SH .28 8 port or the LRP Z .28 motor`s are awsome...

Thank`s

And the only engine that smokes these two is Novarossi 528?

Close but ....for the $$$

Here`s the deal...!

could you post some specs/engine name. I think they are the key

I dont understand, what do 'ports' mean on engines???

its like valves on a real engine.

this picture is a pic of the Sleave of the Novarossi 528xr

each one of those "holes" in the sleave is a port. a mixture of air and fuel enter threw these into the combustion chamber to be well... combusted, then the gasses are exited threw ports too (called exhaust ports).

you really have to under stand how a 2stroke engien works to really get what ports are.

I have a STS D21B that has well over 4 gallons on it and still keeps up with more expensive engines no problem. I just got and all most done breaking in a STS D21B RBmod and will be racing it in round 3 of the Georgia Championship Series this weekend. Will keep the stock one as back up. I all so have a STS 28 for my Savage but with racing just about every weekend have not had time to install it. Mark at STS Micro Engines is a GREAT guy to deal with and stocks more parts for these engines then any I have seen in the US.
