[ Was on ebay last week and not sold i took it off for this project what the heck. i can still drive it and break it] And aha it has a new engine.

Our subject a os .12 max 12TR(P)-T. Nib when installed 1 year back and i did a break in of two tanks and the yadadada and back to the bench err... floor.

The test subject and the rc bible that make made me do it.


The Warning


Ehhhwwww Green Stuff on piston and button head .The process is called oxidation i think , Common in nitro engines that are not used for a very long time.And the fools on ebay never believed me the engine is new.Altough old but still new...



O.k where is the boost port?.. if exhaust port is where the exhaust is and i'm pointing at the right direction.


Marking towards the boost port



More markings.. As they say measure twice cut once.


Ladies and gentlemen ...... start your engines.....




Honestly if there was improvement, it's unnoticeable. Maybe with a proper tool and the exact dimensions to create a proper fuel drain should be left to the experts .

But still i'll post here if i see any fuel savings or if i can flip the v one on a straight .
