i think mugen said the same thing and dropped JP coz of price and now are ninja witch is a cheaper motor.
and kyosho was or still is using sirio witch is cheap too.

i myself will not get another $500.00 motor, its just way to much money
and what iv seen this year where i run,my ninja is just as or faster than the mf,max,jp and novarossi motors.
but with that said i would not get a red dot what iv seen with this motor its not that good but it is good for $200.00 id get it over an os if my budget was at that level.
