Motor question

[speedsport]

Would any one have a idea what kind of amps a 8900Kv motor would pull?

Why is that a DUMB question Castle makes a CM36 9000kv motor for 1/10 scale on road cars......................

speedsport a little more info would be helpful like, what do you planing on putting it in? 8900kv is way to high for boat use unless you are running a very small boat on one 3.7v lipo

Answer..no boat...no prop...no battery and 8900Kv.

That is why I responded that way. Newbies do some research first and most of you do.

The only way is using a gearbox for that. That is the difference in boats and cars.

We used to run lots of gear boxes with big props. 8900KV is pretty extreme but certainly could be geared right for smaller rigs.

I am new to brushless and new to electric boating. Ive only had nitros in the past.

Where would I find gear boxes for some thing like this? The motor is quite small in physical size. I'm into the mini and micro boats.

The only 2 gearbox setups I know of are the FDM tranny and the Hughey gearbox. Both are pretty big so they probably are not suited to small hull. I bet the heli and airplane community have something. Why not just get a small 380 or so motor and not spend money on a tranny? Small B/L motors are very cheap, much less then a tranny I bet.

Ok I have this hull http://www.bbyracing.com/elecmicrohulls.asp its The Micro Patriot. I have a 30A esc laying around and 1/8 flex shaft etc. What would be a good size motor and prop for this hull? I have a extra X427 prop but I think it will be to big. Also I would prob run it on a 7.4 lipo pack.

All though I see they use a X431 prop so it may work.


Thanks

Thanks

on the page you refeered to they reccomend a 480 size motor and a X431 prop (in the artr)

Steve has some Short and long motors here. He is waiting on some 380Xls that would be a great match.

[Rex R]

methinks that if I were to go the brushless route, that one of these http://www.offshoreelectrics.com/pro...-380-L&cat=116 in either 7 or 8 turn flavours would work pretty well.

eflite 2700 kv 28mm x 47mm is what i use in my mini vee on 3s

I also use a stock mini vee prop which is close to a x431 as far as i can tell
