Me too! : )

Thanks, I'll look into getting one

I will say something strange have you thought about using 2-3 eagletree's in parallel?
Should work fine and later you can play with data from both to figure out total draw.

Ok, here is the situation. The motor that I was using for some reason got demagnetized. I will restart the comparisons with a Aveox 1412 motor. I don't know that Kv of the motor, but I will only be running 11.1V and 14.8V. My daughter just came back from PA and I'll wait until school starts to do this.

1412/1 - Kv 2932
1412/1.5 - Kv 1945
1412/2 - Kv 1466
1412/3 - Kv 1011
1412/4 -Kv 729
1412/8 -Kv 528.8
1412/16 - Kv 183

Data from www.aveox.com

With 11-15V it would be easy to find out which one you have.

It seems to be the 1412/1. It took me a while to go from motor to motor, but the one without the label seemed to balloon the tires more then the other Aveox's I have. The other ones are the 1412/1.5 and the 1412/3.

I'll be running a 13T pinion and the 51T spur, but I have 14, 15, 16, 17, 18, 20 and 22T pinions as well. Which one should I use for the comparison? Just want to get some inputs before starting again.

Today I drove the truck and it was a good run. I ran it just over 7 minutes with my other 2200mAh, 11.1V packs in parallel, MGM TMM 160-3s and the Aveox 1412/1y. The MGM didn't get warm at all and the lipos were the same way (Impressive), but the 1412 was a bit hot, not too hot because I could keep my finger on it for over 10 seconds. The real story here are this lipos. This tiny packs deliver some serious power. After the run I put them on the charger and it showed 11.64V and I only put 1806mAh back in them. The only problem is they are only available in 2200Mah sizes. The factory told me they are working on a larger capacity. The graph from the DPR-II-150 shows a max AMPs of 164.34A, but there were a few over 100A+ bursts. The pack didn't get warm at all. The MGM has to be the smoothest controller so far from all the controllers I've been using on this truck. I only wish my Quark 125B didn't burn. I will continue tomorrow, but with the MM and same lipos.

In your data, it looks like you stopped a couple of times. Was that on purpose or did the controller stop?

lutach · 09.05.2007, 01:26 PM

It was actually to see if everything was OK temps wise, specially for the batteries. I didn't know how they would do.

Finnster · 09.05.2007, 02:12 PM

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

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

lutach · 09.05.2007, 02:27 PM

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.

lxmuff · 09.05.2007, 02:57 PM

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.

lutach · **The 5000mAh packs are here!!!! -** 09.06.2007, 01:54 PM

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.
