I got all (well just about all) the electronics today!!! I also got the wood to make the battery boxes today.

Time to make the battery boxes. The hatches will be magnetically attached.

I'll post pics soon!

You guys (and girls if there are any) have no idea how pissed I am... The balsa I received is unacceptable. It does not look like any precision other than "this looks about right" was used.

I ordered 8 3/16"x3"x36" sheets. Only 3 are decently straight. The widths are not precise at all either. The edges are also just cut at approximately the right length and by a very crooked hand. Some of them even seem to get wider/narrower, but it is probably just the curve. I have high standards and I deem this as unacceptable.

I understand that wood is not like plastic or metal, but the same precision can be used.

The pictures do not show the defects enough.

I labeled each lipo from 1 to 6.

Lipo 1:
Overall - 23.11
1c - 3.87
2c - 3.84
3c - 3.84
4c - 3.84
5c - 3.86
6c - 3.84

Lipo 2:
Overall - 23.09
1c - 3.87
2c - 3.83
3c - 3.85
4c - 3.86
5c - 3.85
6c - 3.83

Lipo 3:
Overall - 23.08
1c - 3.86
2c - 3.84
3c - 3.85
4c - 3.85
5c - 3.86
6c - 3.82

I still have yet to get to the other three, but I think this is pretty good.

I started off the morning by soldering on the connectors for the wire that would be attached to the motor wires and the first esc. But in the process of soldering the battery end, I accidentally grabbed the the iron with one finger in front of the grip. I lost part of my fingerprint... ouch.

Pics later...

Try using a soldering iron while laying on shop floor, while getting up from floor I layed back of arm full weight on it. It burned me about 1/2" deep, was sore for awhile. Soldering irons are hungry little critters, gotta feed them alot of lead or they get feisty.

That balsa looks familiar. That's why I only buy balsa I can see and feel myself; of course not all of us have that luck (but, sometimes it's weeks or months before any decent balsa arrives again!)

Soldering irons are horrible creatures, their bite is harder than a tigers
did you you can make a hole in fingernails with a sharp and hot enough iron? *BEEP*

eek, I have done that before. But i dropped it then cached it iron side with my hand again . The first grab was the bad burn the 2nd wasn't too bad since at that point it was basically on the table I just dropped it.

I know that I have not really been making progress on this much lately, but I can guaranty that it will be done by the end of this month. The only aspect that may present itself as difficult is the skirt. So if worst comes to worst, the skirt will be the only part not on.

The motor wires came soldered with some extremely tough solder that we could not really get through. So we took short lengths of copper tubing, and crimped them onto the motor wires. Then we crimped the other end of the tube to the wires that would be connected to the ESC's wire. We basically made extensions. We are not finished yet, but they will be done today.

Did you try a small propane torch? like what would be used for plumbing. I don't trust crimps they become loose and generate heat, fire and foam don't mix well.

I like to use a mini butane torch for heavy soldering. Works great.
