My OS 28 video !!!
 

Well here is a video of my OS 28 I modified.... this motor is fully cut with altered sleeve ports, lightened,filled and timed crank... This motor was able to run 10 minutes per tank at the Canadian Winter Nationals with the 7 mm venturi....I ran it in my MBX5T at the Nationals but it was beyond uncontrollable..But I have swapped the motor into my new Hyper ST Pro and this chassis seems much more comfortable with this kind of power....

Anyways here is the video of a few shakedown passes, still running only 7 mm venturi and pushing a 14 th bell......... I am extremely impressed with this motor, definitely one of the fastest things I have ever seen run..OS definitely did a good job with this motor...

You may notice a slight high idle off the highspeed passes but that is due to a extremely leaky front bearing, motor doesn't even have 1 gallon and the front bearing is pissing fuel already, making a huge mess of the Truggy and Motor..

Cool I just got one of those and still have to break it in. I hope I don't have the front bearing trouble.

nice engine
