motor recommendations

[forescott]

It seems like that would be enough rpm with a big prop. Remember that these motors claim to be 90% efficient, so you have to subtract 10% right away plus anywhere from 10-20% for slip. Also remember that that number is unloaded rpm. Without knowing how this motor will perform, I would stay on the higher rpm side. Either 7s or the 1340kv version on 6s.

Ok thanks so thats going to be my set up now i need to know esc and hardware
i was thinking 180amp esc and this hardware http://www.offshoreelectrics.com/pro...prod=ose-80085

Here is a link for the ose top speed page where you can play with the numbers to get a good speed estimate for you're build. http://www.offshoreelectrics.com/conversion.htm

O.k., thanks! What prop can you suggest to start with and beyond...?

My gut is telling me to go 8S on 1090Kv for some reason?, thats alot of power though...

Need to do allot of thinking because I don't want to get the wrong batch of cells...

9s on my 1020kv in my DF40 runs well.

What props can you turn?

Wow, that's got to be a monster!

What do you think of the 1340 kv on8s

[ray schrauwen]

Steve's 1090kv's are selling faster so far.

[forescott]

The 1090 is a more 8s friendly motor.

I would run the 1090 on 6s with 1/4" drive components and a monster prop.

[ray schrauwen]

Thats odd, is one post somewhat contradictory to the other?

I've got 1/4" hardware, step down stub to3/16", (thanks Steve!)

Just can't decide.... 6,7 or, 8S ?

[forescott]

I meant 8s is better suited for the 1090 as opposed to the 1340. I like 4 to 6s setups myself. That statement was in response to 08gtrking. Guess I shoulda quoted him.

[ray schrauwen]

Thats more like it.

Yes but, I want to nip at some other more expensive Open Mono's heels.

i don`t get it if i run 8s on the 1090kv motor it going torun as fast as the 1340 on 6s?
