Micro Switch vs. ESC

[chunkt]

??? I'm setting up a 6-cell rigger with ROAR motor and debating weather to go with an ESC or a micro-switch. I think I'm leaning toward the micro-switch but I want to here some opinions.

Are you talking about a simple on/off switch? It will have to be able to handle the current.

It will require an additional servo to actuate...more weight.

We used micro switches when I used to race electric drag cars. Only takes a small micro servo, probably equal to or less than the weight of a good ESC. they are great for getting as much power possible at one quick burst, not much resitance either. We use to use a 25 amp switch, pretty cheap 5-8 dollars a pop.

Not disagreeing with ya PJ, just offering my experince ;D

Ok, yeah that is pretty darn light. ESC's have come a long way since ive messed with em!

I have darn little experience with electrics, and you should have some who knows what they're doing look at the specs...but 20 amps continuous...at 0.3 oz?

Propjockey racing.....we run electric (starters) ;D

Well I guess since I have some experience with electric riggers, (all of our rigger designs have been national champions) heres my opinion.

Riggers draw a lot of power. A 20 amp speed control is probably not going to last long even on a stock ROAR 27 turn motor.

Forget the micro switch idea. Even a multi speed micro switch set up will be hard on the motor. Also a ROAR motor is not the best choice for a rigger. The timing is way to far out, and the RPM is bare minimum.

Riggers require a lot of prop RPM to get up and go.

Find yourself a good electronic speed control. The Griffin 55 is a good controller. It has BEC which eliminates more weight.

RTR a 6 cell rigger should be about 2-2.5 lbs. The extra servo, microswitch, and mount, will put you way over this weight.

Thanks Peter & T.F. for your thoughts.

Peter, I'm planning on sticking with the ROAR motor. I know they are a bit lacking for power, so I am intending to pull the front sponsons back a little closer to the C.G. to help unload the prop.

How will the Griffin ESC handle a Mod. motor if I choose to pop one in the tub?

Peter is the Castle water proof? If not look into the Shark esc 6-12 cells, waterproof and bec to save weight.

I happen to like a Micro Switch and use one in my E Ninja. See vid http://www.intlwaters.com/videos/electrico...ectric0003.html

However for heat racing a ESC is best.

E Ninja:

05 motor..19 turn

1732 prop

40 mph.

Lots of Fun
