Posted by Calvin Lin on Friday, August 1st 2008
The Japaneses have always been crazy about their engines, trying to squeeze out the maximum power from minimum capacity. It seems they have applied that to the OS-50 hyper. R/C engine tuning house and aftermarket parts manufacturer, M-Speed, has been selling two types of very modified OS-50 hyper.
Lets start with the more affordable variant at around US$250.
“OS 50 SX-H Reformed”
Features
* 3-needle 60M carb off the 91SZ-H
* Black Coated head for better heat dissipation
* Polished Crankshaft intake port
* Special Con-rod
And then there is a even more highly modified version, the “H817 SX-H” at a cool US$400
H817 SX-H
Features
* Ceramic Bearings
* Lightened Crank Shaft
* Modified Exhaust Timing
* Black Coated Heat Sink and Crank Case for heat dissipation
* Modified for maximum top end power
Yes, all OS warranty will be voided for both engines, but I suppose M-Speed will give customers some sort of support, though it isn’t mentioned on the web page.
