Hey guys,
Ive just received my new Talon... been holding off for a few months... :)
I'm very happy with the quality of the kit..
Ive looked at different options for the power plant... I was preferring to use a 6S battery setup to reduce current load and hence needed a low kV motors...
After some number crunching, Ive come up with this configuration...
Turnigy multistar 4230-400Kv 16 Pole
and a 13 x 7 prop, similar to this

This was one of the pages that I used for some of the prop calculations based on wing loading, model weight etc...

I have attached a picture with some of the ECalc figures and a copy of the spreadsheet that I created based on the RC Group post.
Any comments or suggestions???
Thanks
Adrian

i would transmit an advice I received from senior guys flying the Talon, that is not to start with a 6S configuration because : it is too heavy, it does not give you as much thrust to take off easily (low Kv), it requires more dangerous large props.
I would advise you a 700Kv motor with 13x8 props and 4S battery. That will give you (measured really on field) 1000g of thrust at 50% throttle which is plenty to take off (specs say to have 20 to30% of the total weight in thrust to take off...)
HI,
The description of the motor is showing that works with 4S, but you are flying with 6S, is it be ok?

KV(RPM/V): 400
Lipo cells: 4s
Max Surge Watts(W): 550
Working current: 20 amps
Max.current(10s): 25 amps
No Load Current: 0.6 amps
Intemal Resistance: 0.079 ohm
Number of Poles: 16
Dimensions(Dia.xL): 42 x 32 mm
Shaft: 5 mm
Prop: 14 x 4.7 - 15 x 4
