:) Hmm, nice question. They both nice and foot print is great.
From my viewpoint, before mods:
MM cons:
-Incorrect caps for above 4S (fixed with Mod)
-Poor heatsinking, especially first gen. pcb. (Improved with Mod)
-software handicap above 3S (LiPo cutoff can be sacrificed to make it operational)
-poor enclosure design, come loose very quick, i.e. improper for ESC mounting. (Not addressed yet)
MM pros:
-great foot print
-nice programming via USB
-very smooth with latest firmware
-30 fet's total with 24 top level, i.e. with heatsink
Tekin cons:
-no built in Caps, but cap provided, below 4S operation (Modded one allows 6S operation)
- poor heatsinking, heatsink missing (Improved dramatically with heatsink)
Tekin pros:
-very nice foot print
-great enclosure design
-native software support above 3-4S LiPo
-haven't checked Tekin's Hotwire interface, yet
-48 fet's total, none

Common cons and pros are omitted.

In theory Tekin ESC, having 48 fets (but dynamic losses come to play later), doesn't need heatsink for currents below 50A @ 4S LiPo maximum, but with proper heatsinking becoming very capable ESC with smallest foot print.
While MM in stock form can be good for similar performance, while with the mod1 can get close to current capacity of Modified Tekin R1Pro.
Both have Linear BEC's, so both need UBEC (or separate receiver pack) above 3S LiPo, meaning red wire need to be pulled out and isolated.

Price wise MM is the winner, but which one is better? I am not sure, I like them both.

Thanks Artur for the info and all of your hard work in giving us lucky folk the ability to put an even bigger smile on our faces...

Great list Artur. Just to add some to your hotwire comment. If the MM software and USM programing is great, then the Tekin is very good. Still an excelent piece of software with great programing capabilities, ut missing a couple key things vs te MM. 1st- the thottle curve progaming on the MM and MM are 2nd to none. The Tekin allows changes to a few preset curves, the MM has infinite adjustment. 2nd- WHile I actually hate the usb jack in the side of the esc and would prefer the Rx cble programaing like the MMM and R1Pro, the software on the MM is just simpler and easier to understand than the Tekin software.

Thank you for update, Jeff.

Hey, you drove Tekin R1Pro hard...

[magman]

I'd say...looks like he had some fun tho...

[jhautz]

Actually... I had the capacitor lead break on me and didnt realize it. The esc overheated pretty darn fast runnnig without a cap. But... to the little guys credit, as soon as I put a new cap on it it was running good as new. This time I put a short section of flexible wire beween the cap and the sloder posts. The rigid wire on the cap must have broke from the vibratrion. I had it tied down, but it must not have been enough to prevent a little flex in the wires and it allowed them to fracture over time.

Other than that, it actually ran fairly cool on the meduim to mild setup that I run for the track. I did notice the plastic case got a bit warped after the capacitor incident. It does look rather wonky in the picture. lol

Hey Jeff,
Can I reset ESC to factory default for testing? It is blinking 1,3,5 LED on me, I am assuming custom voltage cut-off. I do not have hotwire at hand, it is coming from tower any day now, but I would like to finish your ESC and ship it tomorrow.

[TruckBasher]

Looks like a pro job to me...

If I had the money i would have bought the one on sale...


Great job Artur

[jhautz]

Certainly. Set it however you want for testing. I'll set it with the hotwire before running it.

How far can the R1 pro controller be pushed? does it handle 5S?

[jhautz]

I ran it for months on 5s in its stock form. It takes it easily. I know that Jim from Tekin even said it would probably take 6s. It has 30v components inside. But I personally havent tested it. With Arturs mod to it its now limited to 5s becasue he used a 27v component on it. But 5s is plenty for me. In stock form it ran my buggy with 5s and a Hacker 10xl geared for 38-40 mph or so without even breaking a sweat on the track.

What is the Tekin R1 Pro's amperage rating?

Far..., as long as software can handle it. Although I do not feel comfortable running close to FET's rated voltage.

What is the Tekin R1 Pro's amperage rating?

SPECS: Controls: Forward/Brake/Reverse
ON Resistance: 0.00005 Ohms (brushed fwd mode)
0.00015 Ohms (brushless mode)
0.00015 Ohms (brushed fwd/rev mode)
Input Voltage: 4 - 9 Cells, 2 - 3S Lipo
BEC 6.0 V / 3.0 A
Motor Limit: Brushed and Brushless, no limit
Throttle Profiles: 1-7
Max Current: Brushed Forward, 312amps / 624amps
Brushless per Phase: 104amps / 208amps

I will assume that stock ratings based on 26A per Fet @ 1sq-in pad with 1oz copper.

Modifications inside, extend current handling and power ratings, but do not overestimate pcb traces current capacity.

[phatmonk]

Thanks for the quick response.

Hmm, looks like the upcomming MambaMaxPro will have some stiff competition. I wonder if castle would consider an aluminum case (of half case even) to aid strength and cooling some how (link it to the main heatsink on the FETS somehow)...
