so far the 50 does not impress me in regards to power in comparison to the 46. granted it has only two gallons of fuel through it... so i give it some more time.
don't get me wrong, it's a great engine, runs great, but has it $70.- worth more of power? not at this point, i will keep you posted as i run more fuel though it, but at this point the power difference seems to be minimal. and i have the DIRECT comparison. i had a 46 in this heli, now i have a 50, everything is exactly the same...
