Anyone using a KB45?

[FE_Chris]

Just wondring if anyone is using a KB45 motor? I have seen them for sale now for a little while. Was thinking maybe someone put together a HV setup.

So let's here about it!

I have the 8-T in the cat. I am working on a coupler so I can test.

I am waiting on the clear coat to set one week and Steven to get the flex couplers in. Using the 10 in a HV setup.

My coupler shipped today. Thatks Steven!!!!!!

I am waiting on the flex HEX coupler, 6mm to .150. I dont see those listed yet. I thought he said he would have them in another week. Did you get the straight coupler with set screws?

[FE_Chris]

sweet, I wanna see how these motors pan out. I have a HV setup ARR on the way, and I figured if I did'nt like the aveox motor, I could try one of these..

And I just wanted to see if it is really possible to power a larger boat with a 75$ motor and get good speeds. Keep us posted.

Thats what I am using. The straight coupler from toysport has 3 set screws. The 6mm to .78 wire Steven attemped to drill out had 4 screws. He made one that had worked out good. The bore was slightly off on mine. Had I been using a flex cable I could have prolly got away with it. But the hub @ the end of my stuffing tube was vibrating enough to make me think twice about turnng up the motor. My new one is in the mail now.

Hey I gota ask...Was it a bitch to install that water jacket? I was cussin up a stom last night. The tolorence between them it tight!! But it's not impossible of course.

I used some vaseline and it went on ok, when I twisted it. I used this on a 540 waterjacket and it has not leaked a drop. I hope this one is the same. Thats probably why they send the extra o rings, cause it can be a beeeotch.

I used silicon shock oil. Prolly should have used somthing heaver. I dinged it ouside edge tapping it with a rubber handled screw driver :-S. I got pissed and grabbed the monster channel locks and gingerly pressed it on.

So...how is this motor performing?
on how many cells?
amps?
props?
heat?
esc?
and if it is a generic motor, for which brand motors?

Found this on another forum.

KB45-11XL 1000kv on a X447 prop 8s1p 5000ma TP Ex lipo. The boat is 13.5 Lbs. I think it pushed this hull about 50 mph with this setup.

It seems to be a good motor and is a good bang for the buck.

Sounds like Steven may have hit another home run for the hobbiest operating on a tight budget.

He must be running it in a 42", 1/8 scale hull, since it weighs 13.5 lbs on lipos. I am thinking this may be my next project. A 1/8 Miss Budweiser using a simular setup.

Sounds promising. I can get a good price on the big 1/8th proboat hydro hulls. A conversion may be worth a shot.

How much? A gas RTR cost about $1100 new.

There is a guy on ebay that deals in product returns..I have seen them go in the low to mid 300s

you can buy the hull and cowl/canopy direct from horizonhobby. the hull is $404.99 the cowl/canopy is $44.99. not bad.

or you can buy the "plans" off ebay and have a lazer shop cut out the parts out of wood.
