Hot Rod = Mega 16/15/5 on 4S1P 2100 mAh and either of the following:

APC 6.3 x 4, 21.7 amps @ WOT 29.6 oz thrust, 79 mph tip speed and a best ROC of 1979 ft/min @ 90 degrees

or

APC 6 x 4e, 19.2 amps and 26.6 oz thrust, 82 mph tip speed and a best ROC of 1691 ft/min at 62 degrees.

{For comparison purposes, the 16/15/4 on 3S1P and a 6 x 4 prop is 22 amps, 23.6 oz thrust, 77 mph tip speed and best RoC of 1517 ft/min at 55 degrees}

I am not sure I will be able to tell the difference between the two props (or a 6.5 x 2.9 or a 6.5 x 3.7 that I just picked up) but I sure intend to try tomorrow!

When flown with a 7 x 3 prop it would draw about the same as the /4 with a 6 x 4, but it would accelerate going straight up at 2100 ft/min. The only trouble was the cells got too hot - no air flow in this bird.

....let's see.... a second mortage will let me buy the necessary packs..... and I could add a second motor..... and that will need a 6000 mAh pack.....etc.
