hi im thinking about putting an STS .30 in my OFNA buggy, what do you guys think of these motors and also a good place to buy them? All the ones on ebay are out of hongkong... Id perfer buying out the of the US...... Also the STS .28 im interested in for my Revo but im just curious if there power rating are correct with 3.6 for the .28 and i dunno for the .30........

Thanks

Kemo

quite the powerful engines to be bolting into your ofna and revo.

The ofna should be able to take it, but I think it'll be stupid power inside a revo.

The buggy will be raced, we got guys with OFNA .32 and a OFNA super .28 so i need something with some power.... The revo is just a basher rarely raced but just for fun..... Were building a pulling sled so i want somthing with some grunt to pull it around...... And im a power freak..... I got a .26max in it now but im not all that happy with it.....

Kemo

www.topspeedtoys.com plans to stock them. Its where I got my STS D21T

Let me know what you think.

the .28 should be enough for you. Savy guys complain about not being able to keep all 4 planted on the ground

As far as the .30 goes... yeah I haven't seen it ran yet because it aint out yet.

The D28M totally rules!!!!
Even when breaking it in, I would pull wheelies at only half trigger! Excellent accleration, good top end, and excellent for pusing heavy trucks like the Savage! In a buggy, it will totally make any buggy rip!

Note: The D28M tends to leak air. As soon as you get it, take off the carb, the back plate, and the piston sleeve and clean it as best you can to remove any machining shards. Then, replace the sleeve and head, and RTV the backplate and the carb body post. Also, chose your fuel wisely, the D28M is really finiky. I recommend Blue Thunder and I recommend you stay away from Rocket Science. Any fuel that is stubborn on startup and warmup as Rocket Science will give your D28m running problems.

top speed should be able to get them too. Just building up the interest!

Cant wait to watch a few trucks go nuts with the new .30

They are great motors for the money. Search the net for STS .28 and you will find a lot of people in love with their motor. Their .21's are pretty good to, but the .28 shines.

I dont know about the .28 or .30 but i have not been overly impressed with the .21b
its done a gallon and a bit and the bearing's have both worn. the piston somehow allows gas bypass and its only fit for the bin or a full rebuild including crank, bearings, piston liner, and a new rod.
In my humble opinion pay extra and buy quality.

Hincappe

and hows your filter? mines gone a few gallons and still perfect.

druid16v

I change my filters religously.
Its also never been above 130 deg c on my venom temp sensor.

Kemo

I've never had a problem with my .12, and I dont plan to have a problem with my .21T anytime soon.

Derag2

I just got my .30 in the mail today..... What glo plugs do you guys use? can i run the same plugs as my i run in the revo... long hots... I also got some A5 i beleive Os plugs and cold Mccoy plugs MC9 i beleive.... What would be best??????

Hincappe

i ran RB7 or RB6 with good success. MC8 would be pretty close to them.

Derag2

I guess what i need to know for is what heat range you guys run, Hot cold meduims....... The book says run hot plugs for breakin since its really rich, but I run hot plugs in everything..... I just wanna make sure it'd be fine in this engine....... Also im gonna be running 20 percent with castor oil added.... so i should be good there...

Any help is appreciated, I cant wait to mount this sucker up and run a bunch of fuel through it..... I need it for a race this sunday......

Kemo

Take time on the break in and make sure you follow their break in method as best as you can. They typically wake up after the second gallon.
