I am about to purchase an ESC, and have always gone down the Mtroniks route before.  It is to controll an MFA Torpedo 850 motor, 12v with a 50mm two bladed prop to start with (but experimentation with bigger props in the future is inevitable!!).

 My choices are;

 Mtronics Marine 40  or the Electronize FR30HX.

 On reading up on both units, the Electronize seems the better unit, and slightly cheeper too .  I notice a lot of builders here go down the Electronize road, and that really should answer my question,  but I love a bit of feedback before parting with cash!! ::)

Hi flybobby,
I have both units and used both units and I believe the Electronize is better....it doesn't have that annoying whine that the other product has and it has NEVER failed unlike the other product.

[rats]

 I was going to buy the Mtronics esc for tug I was building until it was pointed out to me that the MAXIMUM voltage allowed by them is 12v and if you are using lead acid batteries then they are probably producing 13+ volts ( Electronize allow up to 24 v )

[HS93 (RIP)]

 Electronize CAN be repaired very easy Ive fixed one or two (owned by animals) and they are cheap to fix also they do not overinflate the max amps like some others what they quote is what you get all day.  Peter

[flybobby]

Sounds like its the electronize unit is the way to go.  Good point Rats about the voltage, never thought about that.
The whine from the Mtroniks unit does get on my nerves too.

How do the Electronize units stand upto water ingress, as the Mtronics are waterproof*?

Just a note for owners/builders of largers tugs, with correspondingly larger motors and hence starting amperage, Ive found that its the starting amps that tends to weld the relay contacts closed with the Electronize models, but never any problems in normal sized tugs.
However although they dont advertise it, they do one with 'remote' relays that can be replaced 'on the bank' so to speak. Apparently they do them for the 'robot' guys who are prone to thrusting larger metal bits around and require the heavier relays, they suit larger boats down to the ground...really surprised they dont offer them to our guys in their ads though.

You may want to think about size and space availability as well.

In a large hull with all the space in the world go for what you think is the best.  I have both and have had not problems with either but the Mtronics is easier to set up and readjust if you want to change your transmitter.

It is also better sealed against water but the Electronize is obviously easier to repair.

hi there flybobby

Ive personally used Electronize on a lot of my models - I cannot really vouch for Mtronics because Ive never used their gear.  What I will say for Electronize - is - yes, slightly bulky about the same size as a packet of 20 cigarettes - but, as has been said on this thread they are a very hardy and robust speed controller.  To give you an example, I ran two 600s, drawing about 25 amps on a 15 amp speed controller.  The thing never cut out once  you could fry an egg on everything  but, it just kept going.

About as well as a reciver  ,get em nice and hot and the water just boils of. they are not potted like Mtronics .but because they are potted they are not repairable.. also if you want to say you built all your boat get the kits, they are not that hard to build,Peter

[OneBladeMissing]

It should be easy the block the cable exit holes on Electronize units with silicon sealant.

[justboatonic]

Id go Mtroniks everytime. They have a track record for providing quality speed controllers with a very small footprint. The electonize looks very agricultural by comparision.

The correct rated Mtronik esc will beat the pants off an electronize for reliability, performance and reliability especially if used for racing electric boats.

[flybobby]

The electronize maybe a larger unit, but size isn't an issue with this boat.  I like the idea that it is repairable too.  The electronize seems to fit the bill for what I am after, so think I will place an order.

Thanks all for your opinions, its nice to be able to dip a toe in the water before jumping in head first!!

silicon sealant destroys electonic parts   .Peter

Mtroniks are very water prof thank god

Hi all, Both products work well.  We had a little problem with Mtronics on a RNLI boat for public use at our last but one exhibition.  The over enthusiastic youngsters could whip the throttle control back and forth and the ESC could lose its position and do nothing, but I think this was an abuse of the ESC.

I have used Electronize for many years.  This may be of help as I watercooled one with a simple brass plate sealed to the base of the existing one. The sealing is done with electrical stuff for transferring heat, mainly used in heat sinks.
 It had 2 aprox 1/8 inch brass tubes soldered to it each protruding over the ends.  One pair of tubes has a plastic tube connected across and the other ends go to an inlet and outlet plastic tubes for picking up and discharging water from points in the hull.
The ESC was running at full power, a measured 15 amps and stayed stone cold.  It was driving 2 off Speed 600's on 12 volts, which is 180 watts.
regards to all Roy

I use an Mtronics with a 12v SLA - no problems!

I agree, both are good. I also use Action ones - same option of building it yourself, but smaller than Electronize. I only have experience of the Pico and Condor 2amp, but have just built a Condor 10amp.

Both

[malcolmfrary]

I thought that the best way to sort out whether Mtroniks were OK on a 12 volt SLA was to ask. 
Here is the reply -

This should answer any queries

[Ghost in the shell]

for 12v id use the Proboat 50 :)

[Tug]

I like the electronize

My big tug  46"  loads of room for air circulation,

uses 2 12 volt batteries to give 24 volts, and a bigger motor draws less amps at that voltage, (rated 30 volts)

also saves putting in  [more than] 12 pounds of lead ballast

and the biggie..... Electronize repair them at a standard price including postage [UK] of a tenner
