ok guys this is my report on the OS .25xz , going my 3rd gallon on it running it still with the stock restrictor (9or8) with os 2050 pipe , it like to be ran around 220deg and with 1.1 clutch springs , why , it has soo much torque on the bottom that i snapped and broke 2 sets of 1.0 springs and broke in half a set of alum. clutch shoes besides that it doesnt have problem pulling away from 21 or 28 motors in that case "just cause i did" and the guy ask me what i was running and i told him the os 25xz and he had in his rc8t a 28xz "jajajaj sucker" well i tell you this , he pulled out a new 25xz out of his tool box and switch motors
my 25xz pulls just about the same as my friends os 21 speed , take that for a tip......

Donrod,
Great to see you guys at the Nats! That motor was awesome and Dylan was driving awesome Very impressive! What restrictor and clutch springs are you guys running?

Well, my .25xz appears to have eaten a glow plug at just after a gallon.
I was planning to run it Saturday. Last time I ran it (practice), it flamed out and wouldn't fire. I figured it was a bad glow plug, and packed it up for the day. Saturday morning I pulled the plug to install a new one, and the coil is gone. Engine ate it. I'm so freakin bummed out I haven't even taken the thing apart yet to see what the damage is.
Good thing I have a couple JPX .21s I guess...

Nice meeting you guys as well, we are using the 8mm restrictor with 1.0 springs with the 2050 pipe. We are very pleased with the motor.

What size bearings does it use?
Anyone know the bearing sizes for the 25XZ? I'm curious to know if it uses .21 engine bearings and a 14 mm crankshaft (?)

Hey Nitroluver
At my local track for a 2 day trophy meet, I was running an os speed in a losi 8t with a 9mm insert and this other quick driver in a xray truggy was running one of these os .25's with a 6.5mm insert. Both of us were running os 2060 pipes but different brands of fuel.
I have got to say that after seeing the performance of these os .25 motors, It has made me go out and buy one for my truggy. It simply had the bigger displacement to get the truggy up and out of corners alot faster than what my os speed could. Coming onto the main straight, I would be 2-3 metres infront of the other guy with my os speed but by the end of the straight, he would be on my ass and this didn't include the tight and technical sections of the track. My os speed needed a main straight another 20 metres long to wind up and get going where the .25 had the guts to get him out of the corner alot faster and get the truggy motoring proper quick.
I was a bit spectical about them at firsst thinking they're going to be a clutch and diff killer but after having a drive of a .25 in another car, they're not like a toggle switch and uncontrollable but simply a superb truggy motor to get them out of corners faster than anything else and I also think revving down the main straight just as good as .21's.
My .25 is currently still sitting bnib but after I get back from my holiday, It's definitely getting run-in and whacked in my truggy.
Cheers.

Fuel economy was my biggest concern as all os speeds have been known for great run times. If I ran a 7mm insert in my truggy I could do 10 minute pitstops at any track but when I was running this 9mm insert to keep up witht the pace, I wasn't able to do 10 minutes and instead had to come in and pit at about 8mins or stretch it to 8:30.
The other guy running his .25 could have done 10 minute pitstops and had an advantage over me but decided to play it safe and pretty much stick with me when I came in for fuel so the run times there also. Obviously he was only running a 6.5mm insert but he simply had the displacement to still be faster out of the corners and then still great fuel economy.
