View Full Version : Good motor?

I have my half 8 on the way along with bearings, oil shocks and a rear carbon fiber shock mount. I like carbon fiber. The next thing I will get is a good 8-cell saddle battery pack and a better servo as well as more carbon fiber.

Then I will want to get a good motor, which I am sure I will have to get a better ESC and a receiver. I do not need the fastest motor but I want more then stock. What I want is a good torque motor that does not get overly hot. I will be running mostly on grass.

I do not know if this will fit but has anyone had any dealings with a Pro PK 370? I have one in my HPI micro RS4.

That motor will be too small. See the motor comparisons in the motor section for the best selection.

So the motors in the half 8 are size 400? Do you have any recommendations for my needs on a motor? I read that thread but not sure it addressed my question manly about torque. Correct me is I am wrong. All so do you have a link on the Rocket 400? With these motors I a presuming I will have to change the stock electrics?
Thanks!

nope, no need to change anything. all the fast 400 motors will get hot. I don't think there will be a better-than-stock motor that is cooler than running stock. Go with the rocket because its cheap, and doesn't get into calvin temps like the 400 4.8 graupner....and if it does fry, you are out 9 bucks lol

...Moose is our resident brushed expert...I can back up what he says...Motors are expendable items...they are like soap and toilet paper...And taking that into consideration you want the best value for money..and that is the rocket...PLUS you DONT have to swap electronics :D Best on ALL accounts...When you graduate from that motor you WILL want the AON ;)

Does some one have a link?
Thanks

Thanks! But you say the X speed is faster?

no, xspeed is not. The fastest of the group is the Graupner Speed 400 4.8 volt. It will have the most power and torque of the bunch but gets hot enough to melt the epoxy inside the motor. If you run 8 cells, I would stick with the Rocket...but if you go 6 then the 4.8 is what you want

Do you know anything about this motor?

It will the same or slower than stock. The stock motor is either a 7.2 400 or 6v 400. The higher the voltage on the 400 motors, the slower they are.. hence the 4.8 is fastest....but also the hottest at 9.6 volts.

I understand what you are saying about voltage. So in the motors you recommend the voltage in the title are what is recommend to run on and the voltage in the specifications is maximum voltage correct.

All so can some one give me the outside diameter of these motors?

more or less, motors aren't really supposed to be rated that way but thats how all the aircraft motors are....brushless is very direct though "this is the rpm you will get per volt"..."have a nice day"
Those motors have the exact same dia as your stock one so you can measure that and get an idea. hobbylobby may have additional info too.....but I have never actually measured them

BIT-thanks for the props, now where is my AE68 mini-z j/k

Thanks I will measure it when it gets here as I am still waiting. Should be here tomorrow or no later then the first of the week. I just got some of my hop ups in today.
Thanks again

I run 8 cells on my H8 with the rocket 400 with the stock gearing and it still frys and smokes after a few minutes, then it runs again. WHAT CAN I DO ???

really? Make sure you have vents in the body and maybe try adjusting the motor timing...my rocket would get hot, but only about 160-180F.

i dont have a temp gun but when it smokes i lick my finger and touch it and it sizzles, how do i adjust the timing?
