motor and esc question?

I have a RCtimer 50 amp ecs: specs below;
Continuous current:50A
Burst current:60A
BEC: 5V3A
PWM: programmable - 8/16K
Battey: 4-12 Ni-Mh/Ni-Cd or 2-4 Lipo

and a Turnigy 2836 2350kv motor
Max performance;
Voltage: 3-4S Lipoly
Prop: APC4.7x4.25
Thrust: 800g
Power: 480W

I want to know if it is okay to use this setup in a skyfun with a 6x4 prop.. would there be any problems?

any help would be very much appreciated :)

You would need to run a smaller prop in order for it to work on 4S, the larger prop will draw too much current. Looking at the specs, the 4.7X4.25 prop would probably be the biggest you can run on 4S.
It is .25" more pitch speed than the one you suggested, so the plane should still be plenty fast.

No the ESC is fine. The 6x4 would be close on 3 cell.you would smoke the motor before the esc gave in.480 watts would be ~40 amps so you would have 10 or so to spare on the ESC.

thats very good, you could even look at a prop that would load it a bit more.
maybe a 6x5 or APC 6x5.5 E as the planes speed increase the wats will come down.That must be what the programe you have shows??

what does it say for 14.4 volts(4 cell) are you up over the 425~450 watt mark??
that would put your amps ~ 31

If you were looking for more speed i would try the 6x5.5 apc,the amps will be the part that makes heat.I take the watt rating on motors with a grain of salt.480 watts may be max but for how long and what kind of cooling??a lot of times the wire will be fine but the type magnets that are used the heat can damage and can not be fixed.if they get to hot they get weaker.
