What speed controler?

I whant to run the stock motor and run two 3 cell lipos 6 cells, 5000ma with 40c rating and what prop should i use i was thinking the stock one. :Peace_Sign:

Dump the stock prop, you will get better results with a metal prop. The plastic one will flex under load. Prop's I would say a Grim 42x55, x442, x440/3, grim 40x52/3, m440 or a m445. Depends what your really looking for. The x442 or grim 42x55 would be my first choice. That's just me.

For 6s esc's your gonna get a bunch of different answers. The most common will be:

- Seaking 120 (turnigy marine 120)
- Seaking 180 (Turnigy Marine 180)
- Hifei swordfish 120 (turnigy aquastar 120)
- Hifei swordfish 200 (Turnigy aquastar 200).

* Those esc's are rated for 2s-6s, I don't like running esc's at the highest rated voltage. Just a personal thing. Many people have done it and have had good results others not so good. I don't even bother attempting. I would run a seaking 80HV (turnigy marine 80hv) if my intentions where to run 6s on this motor/hull.

Thanks man so i should run a turnigy 80hv why not a 120 wouldent that give me more (screwup room) or not ? im kind of new thanks

Voltage reasons. The 80HV esc is High Voltage rated 5s-12s, the seaking 120s are not high voltage and rated 2s-6s. The 120 would work by all means, like I said I just don't like pushing the esc's to their max rated voltage. It's just a me thing.... The 80amp is plenty of room, the stock is only 45amps (so they say, its really more). The 80amp esc does not have a built in bec so you will have to run a seperate battery source for the rx, the 120s do have a built in bec but you should dis-able it when running that high of voltage. Make sure to change the deans plugs out and also change the motor 3.5mm bullets.

The 80HV are not used typically because most RTR setups are 4s which the 80amp is not rated for. The esc with the most possible application would be the 120, 200 or 180 mentioned above. Just wanted to throw that in their.

Thanks for all the info diesel this is going to be fun . TO BAD its snowing out I guess itel give me time to buy stuff LOL

Like Diesel said, you shouldn't have a problem running the 120 or the 180 on 6s as long as he props it accordingly and runs a motor no higher than the stock kv. I understand exactly why Diesel doesn't like to push the RSCs to their limits though. A lot of people get crazy and try and run high KV motors on 6s and that's what kills the speed controls.

I would run ether ESCs on 6 s with no motor larger in KV than the stock 1500kv motor. That's 33000 rpm. So if you run the stock motor on 6s just make sure you prop is down to keep the amp draw under control.

I always thought it was the amps i had to worry about .

You do amps are a MAJOR deal, but you gotta make sure the esc can handle the proper voltage as well. Like I said a 120 or 180 WILL get the job done, but in this case the stock motor if proped correctly doesn't pull crazy amps and the 80HV would be nice on the stock motor with 6s and the esc wouldn't be pushed amp wise or voltage wise and you will have a nice reliable setup. Just a thought.
