More Time
I am running 6 cell 3300's on my Kinetic 50 conversion. I have the align 600 motor. I only have this set up for sport flying because its going in a scale fuselage. Can the pinio be changed to give me more flight time????

The best way for you to increase your flight time is to remotor and regear for 12S. Average current drops considerably as do the stresses on ESC and batteries. With sensible gearing set to run the motor at ~ 90% governed at 1500-1600, you EASILY get runtimes of 8+ minutes for hovering and gentle FF.

12S with 3300's, BTW, works really well. Just use two packs in series.

Is this 1 6s 3300 pack or 2 in parallel? Cheapest way is to get a smaller pinion and run higher throttle curves, ideally gear for the slowest headspeed you require using 100% throttle.

Whats the main gear tooth count? And is it the 1220kv motor?

Gear is my gear set up

Pinion----19t
counter gear----55t
drive gear----14t
Main gear-----60t

Align 600 motor--1650kv

I'm not as worried about the time as I am the heat.(Other Post).

Thanks

Pinion 19? Main gear 60? Either you have read that wrong or that would explain the high motor temps! Main gear 160T maybe?? Even then the 19T pinion is way too big. Is the drive gear actually the pinion (14T)?.... still too high!

With that motor (1650kv) you want a gear ratio of around 1:17, this is worked out by dividing the main gear tooth count by the pinion tooth count e.g. 170T main, 10T pinion = 17 so thats 1:17 ratio.

As you are wanting a cooler motor and longer flights you want an even higher ratio as 1:17 would give around 2150 rpm at 100% and 0 pitch. Ideally you want a ratio of 18 or 19 with that motor to do hovering and scale flying but I doubt you will get a pinion small enough.

May I suggest Aligns latest motor the 600MX which is 1220kv and will allow much more gearing options and runs far cooler than the old 1650kv motor.

Just to add to Richardmid1 suggestion on the 600MX which is spot on.
The 600MX runs cooler that the old Align motor even when they are geared right. Another good motor would be the scorpion 1100kv
before the 600MX came out the was the goto motor to replace the old 1650kv motor

Ok, that gear setup with that motor on 6s will give a max head speed of around 2950 RPM! I would definatly put a 13 or 14T pinion on the motor shaft, 13T would give you a max of around 2000 RPM, personally that is what I would run for sport flying at 100% flat throttle curve in idle up and something like 0-70-80-90-100 for your normal throttle curve.60% of the time, it works every time!
