What batts are those? Those are impressive #'s.


I really like the sound of the MGM controllers the more I hear about them.

I will actually start distributing those lipos after I'm done with the abuse. I'll try to get around 50 cycles on them before I make a decision. I'm still trying to figure out a name for them or I should just go as is without a brand name and just offer great cells and put at nice price and warranty on them. They come in 3 voltage range: 7.4, 11.1 and 14.8V. I don't want to jump on this right away and have problems later on like some other companies are having.

Thanks for following up with this thread and the data. For the kinda work that I do.... "you are just another opinion without data".

Just came back from running the truck with the MM. Well let me start by saying the weather was a bit cooler than yesterday's run with the MGM. It is around 74 degrees and everything was just perfect. I ran the truck for over 10 minutes and stopped for a while, because of a spectator LOL. The MM was warm and the batteries was around 90 degrees. Now I said everything was just perfect and that "was" is due to the darn DPR-II-150 not recording the run at all. Came home, plugged it to the USB port, opened the program and got slammed with a "No mission data available". I wouldn't mind if the truck wasn't performing good, but it was just too good of a test that this had to happened. The Aveox took a beating and it was hot after the run. This truck did some nice wheelies, full throttle and hard braking. Tomorrow I will run it again and hope that the DPR will record some data.

The 5000mAh packs are here!!!!
 

Good news folks. The 5000mAh packs are here (2 7.4V and 2 11.1V) and so is a really nice small 1600mAh pack that was sent with the big packs for me to try out in my Xray M18. I soldered some deans before I went to get my daughter from school and I guess one of the plugs went bad. It kink of freaked me out as it read 7.65v when I plugged to my AF109 and then it went down fast. I got my alligator clips out and found out it was the deans and not the pack. The 5000mAh packs come with 10GA wires and they are very good quality wires too. I will run the 2 7.4v tomorrow with the MGM 16016-3s and hopefully the DPR will record some data.

Did a good run today with the new 5000mAh 7.4v packs. Good thing the DPR-II-150 worked this time. I only ran it for 8 minutes or so. The MGM TMM 16016-3s ran smooth and cool. The packs were also cool and the Aveox was cooler than yesterday. This thread is turning out to be a battery test session than a comparison of ESC. I have to give my hands to MGM on making an incredible software for the controller. I have it set up on the following modes:

A: 3 (Car mode one way)
B: 1 (Light)
C: 1 (0.13 sec.)
D: 1 (Automatic)
E: 1 (Slow reduce rpm)
F: 1 (NiCd, NiMH)
G: 1 (3%)
H: 2 (Yes)
I: 2 (Yes)
J: 1 (No)

The other setting that I tried made the ESC act funny specially the J set to very light, it didn't feel very light to me LOL. Here is the data of this run.

could you zoom in at a few high amp peaks so we can see the voltage drop better. thanks

nielis,

Here is just the voltage curve.

these cells are very good, around 3,6v @100 amps.

is the price in the flightpower range or lower?

This are the Kong Power packs. I'm trying to become the distributor here in the US, but I heard other companies have tried as well without success. I know one distributor sell the 2200mAh packs really cheap, but they don't carry the 5000mAh packs. You can buy it directly from Kong Power's website. I heard a few people are having a lot of trouble with their TP and FP. The Kong Power packs won't puff, you can go as low as 2.2v per cell and they do run cooler.

How cheap is really cheap? Do you have a link, as I would like to see the sizes of the 2200 cells.

This may seem like a basic question, but what does the different amp ratings mean?

TMM6018 vs TMM16018?

Thanks

It should means the 16018 can put out 160A and the 6018 only 60A.

Ran the truck with the MM and it seemed to have performed better on 4S than with 3S. Power to spare. It wasn't as smooth as the MGM, but it seemed to deliver a tad bit of more power. Ran it for around 8 minutes and the MM was warm and so was the batteries.

Some pictures of the MBX5T.

One more.

Here is the BPP truggy.

Couple more.

I wonder if it would be economically feasible for the smaller controllers (~25A) to incorporate a bucking switching regulator. This would allow use of 6s+ lipo and it would bring the input voltage down to 3s-4s levels. The batteries would then be cheaper since the battery current would be much lower. Not sure if the expense of the added circuits would outweigh the cost savings of the cheaper lipos...

Could something like that be built as a stand-alone device, and plugged in between the esc & battery? Or am I being thick again?...

Most certainly could, but it's usually cheaper to have something like that built in.

What would that do exactly.

Beyond my expertise, but it sounds complicated so must be good...:eyes:

Allow the use of cheaper lipos that don't have the C rating to sustain high currents.

That would be nice. The 10C rated lipo packs are very cheap now LOL.

Today my Aveox 1412 1y failed on me. The shaft came unglued from the magnet assembly. I tired my FDM (Feigao) 7XL and the MGM 16016-3s didn't like it at all. The spur is 48T and pinion 14T. It thermaled after 8 minutes. I thought I had glued the front end of the motor, but I just did the rear.

Cant you glue the magnet back onto the shaft, I heard JBweld works well for that.

I'll actually try that. I was going to have Neu Motors do a little cleaning on it and replace the kevlar around the magnet. I can always have that done later LOL.

Oh of-course, I forgot that Neu stemmed from Aveox, so it makes sense that he is willing to work on it for you. if the Jbweld isnt successful then having them fix it up good as neu* for you you is great.

*Do you see what I did there, I made a funny....

I think "neu" means "new" in French LOL. I love all my Aveox's.

I just found out today the Aquacraft SV27 brushless motor is a 6 pole beast LOL. The magnets are super strong and the assembly is well built.

supervee motors are very good, Guys on the boat forums have tested them to at least 3/4 of a horsepower. The 45 amps speed control that aquacraft use is also very good. Guys run 8l motors on 4s thru it so it is pushing much more than 45 amps. It also works with a wheel transmitter. Ido not think it has brakes, but it would be ok for use in something lighter weight with mech brakes.

The Aquacraft motor is very powerful. I will stop running my RCs for a while. I'm trying to test some batteries and ESC, but every time I go out something goes wrong. Today I just fried my BK 3695. My MBX5T somehow lost my signal and it went straight into the curb, broke my servo holders and the motor kind of came apart. It is strange how everything started going wrong in the past 4 weeks. Today 3 of my RCs kept losing signal. All 3 have different crystals and I use a M8 with a synthesized module. So I'll take some time off.

Today was a good day for the BPP truck, but the MBX5T will have to take a breather. I had some interference problem with my Airtronics M8 so I went with my JR XR3I. It seems that all my FM radios get interference at this parking lot. My Spektrum does fine. Today I just simply lost signal. I forgot to put my failsafe and paid big time. The MBX5T hit the curb at about 40MPH and almost everything flew out of the truck. Nothing broke, but I bent the Front Lower Arm Support. The 2 2S 5000mAh KongPower packs are incredible and they took the hit well. This packs are built tough. I will sell all my FM radios and stick with Spektrum.

Forgot to mention that the motor's rear end popped off and the motor mount bent in a way that I might not be able to fix.
