Brushless for Ripmax Coyote?

[stuey]

Hi chaps, I am pondering swapping the 400 can motor in an old but good nick Ripmax Coyote for a brushless. It would most likely be flying with a 3S 2200 pack and a 30A controller I have them lying around. As I understand it the 400 has a kv around 2200, but that does depend on whether it is a 6v or 7.2v version (I need to check). The current prop is a 6" folder, I think a 7 or 8 inch prop would be more in keeping for efficiency. I reckon I'm looking for an inrunner with a kv between 1500-2000, or possibly a smallish front mounted outrunner if the wires fit inside the nose. I wil weigh the model with a battery to get a better idea in terms of W/lb.

Anyone got a good recommendation?

Thanks for reading

Hi Stuey,

I had a look on the SLEC website recently & noticed that the Coyote has been
reintroduced as a kit - which is good news.
They recommend this setup:

1 Brushless Motor KMS2208/09 --- AXI 2208/34 or similar power motors
1 15 to 20amp brushless speed controller or depending on the motor used.
1 11.1 volt 1300mAh Li-Po Battery.
1 8 x 4 Folding Propeller (SL140-R) fitting directly onto the motor output shaft (available from the Slec Web Site)
It is not recommended to fit motors that produce more than 2000 KV rpm without first changing the folding propeller setup.

Much cheaper than an axi etc

Thanks Tim, looks like a good bet. Having the link Richard posted helped confirm the size/kv range I have been looking at.
