Reviews for O.S. .28XZ Competition Truggy Engine (Turbo Plug) [OSM12830]

I've owned them all(528,trinity drake,vg30,etc)If you want a BIG power and fair run time motor this is it (7.5 to 9 min.)Easy(typical os)break in and easy to tune!Truggie monster truck only don't even try it in your buggie!

Man...! I dropped this engine into my brand new Kyosho Inferno ST-RR, and WOW! It kicks butt! Perfect for Truggies. Almost too much power (if there is such a thing). It started right up, right out of the box! Breaks in smooth also...even in winter. Before this, I was a Sirio man...but O.S. finally won me over. Great Engine!

ALWAYS BEEN AN RB GUY,GOT TALKED INTO TRYING THIS ENGINE, AND IT IS SWEET,HAS HUGE TORQUE, PLENTY OF TOP SPEED, WITH THE RIGHT PIPE ON IT, BEST OF ALL, WAS BLOWN AWAY BY THE FUEL MILEAGE IT GOT.WITH THE SMALLER CARB INSERT ,I WAS RUNNING 12 MINUTES,ON A TANK OF FUEL, COMPARED TO MY RB THAT WAS GETTIN 8-9 MINUTES ON IT.

amazing engine...
i have owned LRP Z.28, Picco 28, Jammin 28, Werks 28, RB TM928, Novarossi 528, but this OS 28 is amazing for the truggy with OS 2060 pipe.
this engine is very dependable from OS pipe.
with a normal pipe like Jammin JP-3 it is a good engine, but with the new OS 2060 pipe, this engine become a monster... 8.5min. of run time with 8.50mm restrictor. same rpm as a picco 28, but incredible acceleration (about like RB 928) i run 14t clutch bell on my kyosho ST-RR and this configuration is perfect...

EXCELLENT...

i do not have this motor yet, but as soon as i am good enough i will. a friend of mine who is a consistent a main participent and just rails around the local tracks says this motor just flat out blows everything he has tryed out of the water. his losi eight truggy is way fast and just screams on the straights. just watching this has convinced me and the fact that he says its the easiest motor to tune he has had and believe me this guy has been through alot of motors( and a ton of moola). i cant wait to get one. as soon as the wife turns her back!

OS has raised the bar with this engine... right outta the box and after run-in this thing SCREAMS! i run on huge tracks in Thailand and this thing is PERFECT for my mugen mb5xt... any serious racer should consider this as a bargain!

Im not a OS man however WOW this motors is sweet, alot like my hot mods RB 928 just smoother. i have 3/4 gallon on it and its just coming alive i dont think its gonna be as strong as My 928 but i believe it will be more then enough and prolly get better run time.

Awsome engine! Little bit hard to start with kyosho starter box but after it gets broke in it starts up with no problem. Awsome torque and really fast!!
