Well ,to turn back some years ,when I bought my 4.6 Mgt. brand new ,I wore out the 28 engine ,LOL....
I ran it every day non stop!
Then I seen the 8.0 versions ,an I wanted bigger power ,but all I got ,was a bigger headache ,it wasn't really
the engines fault ,it was mine ,not knowing about the Mix meter setting as I didn't even know that it existed ,I
am old school guy ,an just stepped back into the RC world after a long time.
Well ,I flooded the engine an threw it into a hydraulic lock with a high power drill start an shattered the engine ,the second
one that I bought ,the muffler fell off ,an I continued to run it ,an the engine burned up with out fuel tank pressure ,it
leaned out an fried the engine ,that's why I urge people all the time to always keep the fuel tank clean ,an keep the pressure
from the muffler to the tank in check .an also ,never try to run an engine with out the muffler on!
as far as the Hpi. 5.9 or 36 size engine ,its a descent engine ,reliable an strong ,also ,gets good fuel mileage!
I am very pleased & happy with the 5.9 in my basher Mgt. for the weight of it is ,due to some of the aluminum parts ,
I also run aluminum wheels on it ,but I also had a steel rolecage on it at one time!
The 8.0 is a fuel hog!.....
