But I seriosly think that the 2w-30 will be a great motor on 6S for this motor... anyone test it out yet?? i want to get my f-18 back in the air!
I've been running the 2W-30 on 6S for a few weeks now. Fan is unbalanced and doesn't sound as nice as some of the other setups yet, but it makes a ton of power on 25C nanos and pushes my Panther Lander to ~95mph.

Go for it, you won't regret it!


P.S. there is also an 8S option with this motor.... if you have space and the guts

It was the shaft that was bent ever so slightly.

I have to give credit to Hobby-Paradise.com who after asking me the right questions, confirmed the issue and are sending me a new motor in replacement without me asking for it.
Nice.

I would just run spool up the motor a little... Maybe 10% throttle... And listen and watch for imbalance... When these motors are balanced, it is the smoothest sound in the world!!! If it wasnt balanced i would just push on the shaft.. Oh yeah i did this with the shaft adapter on... So yanking and pushing on the shaft was a lot easier.... Then i'd run it up again to see if i'd made any progress.. Agin like i said before trial and error. Eventually you are bound to get it.... Luckily it only took 5 minute for me!!

Ah, with shaft adapter I can see it being twice as easy...

good idea

Yup! You dont have to push or pull hard sometimes the least amount of pressure is all it takes!

surely if you can bend the shaft that easy what will happen with the centrifugal force of a fan when you turn quickly. Does not sound like a good fix to me, get a new or better shaft, better still get a better motor

Cs 10

Hi :
I forgot to ask in my last post, how do you measure RPM on the 10 & 12 bladed fans.
I have a tach for 2,3 and 4 bladed props, so do I set my tach on 2 and time it by 5 or do I have to buy a new tach .
Thanks

Get you a KV meter.

http://www.hobbyking.com/hobbyking/s...KV_Reader.html

Beware though, this one shows what you would assume to be 2 pairs of positive and negative wires coming out where you could solder on some deans connectors but mine came with the xt connectors soldered right on the pcb. Luckily I had one male and female xt connector lying around.

I emailed hobbyking about this and told them they needed to change their picture and they didn't seem to give a crap.

Other than that it works good.

They are located in the U.S.

http://www.rchotdeals.com/Products/rc/contactus.html

That's the price you pay since its made in china then they ship it over here. Take your pick, I give up.

I have bought through Hot R/C Deals before, and they are more but at least they are in the U.S. and they have the correct plugs.
I Thank You.

CS 70mm shroud dia.

Im thinking about starting back on a build that has been sitting for quite some time. Its a warthog, I have built the pods for minifans and the fit is perfect to them. I would like to use the CS 10blade fans. Can someone get me a very accurate outside and inside shroud diameter in millimeters.

hi Dave
I would highly recommend that you not use the cs housing as they are crap if you already have them fit to mini housings just use the cs 10blade rotor in that housing otherwise use the delta v15 housing. Tam sells the rotor dynamically balanced with a 4 or 5mm shaft adapter and spinner washer. that would be the way to go
