Smack dab in the middle of Iowa. I work outside all year round, so I thought I would be tougher, until I went outside this morning with the dogs. It was -43 then.
I realized,that cold is not fit for man or beast, let alone a drone.

Why do you call your dog a man??

@dirtybum you were not kidding when you said this stuff was expensive.

50 bucks gets you this (pen not included):

Yeah that flux is no joke though. A little goes a long way, the flux will last you forever, it's the wire that runs out. Do some test solders on some junk equipment, let me know what you think.

I don't know if that wire is anything special, I'd be interested to ask the company

Give me an example of hard to solder metals and I will test with this and then regular solder to see if that wire is special or not.

To me It seems like you payed too much.

I bought this stuff https://www.amazon.com/Harris-500K-...rds=Harris+500K+Al-Solder+500+Aluminum+Solder when i was splitting lipo batteries and it was the only way i could get the solder to stick to the tabs. It was like a miracle for me. The last time i used it was on lion batteries just to be safe i could make the solder stick fast so i didnt have to heat up the battery too long. I don't know if it actually helped but I didn't want to take chances with them.

How much do they weigh ? Probably to heavy you will get auto landing a lot on anything over 600g if you stop moving .

Its really hard not to go in on that DB! That was my favorite battery. I cant believe you found them they look brand new. Unforunately I cant and have battries in boxes I never even used.

Yeah they are rare. I might still get one, it was one the top performers on the p3. I can always use it on p3 if it don't work on mav2.
Here was my last MS8000

Is there a good story behind the pics?

It looks like you need to order the wire separate and cost comes out about the same:

I could fill a whole scrapbook of pictures like that one. Any flight that ends that way is a good story! So yeah I got lots of good stories.
That particular flight was trying to beat a previous personal best and at the time p3 record of 62,000 feet. I was going to come up a mile short. I needed to make it across a road to have a good place to lay it down. Just didn't quite make it, smacked the concrete pretty hard. That ms8.0 was a good balance, and like Chazz commented, was one of my favorites. But the fact that it smacked and I couldn't replace it, lead me to try it's bigger brother the 10.0, which is a really good battery and did some amazing flights

I stand corrected, that link chazz sent has a small spool of aluminum solder wire in the container. The best I can tell, it appears to be very similar to the one dirtybum sent me. So that was a good price.

OK, I did skyninja's pseudo battery clip mod on my other M2 by harvesting an old MP battery clip. For those of you that have not tried any M2 mod's yet, they so far have been exponentially easier than the MP (or maybe we just have more practice)

This would be really no better than the clip mod would it considering how it is connected? Just asking.

It's no better. This was back in the day when nobody had a shipping M2 battery clip available so we harvested M1 clips for this.

There is no clear +/- power junctions on the M2 like we had on the MP. I went over to the battery controller mod thread and started the first power mod there:

Hey @beanbubba have you talked to MacLak lately?
