as an example of battery weight "refinement"

instead of adding an ounce of lead into the nose of a MIG,

HydriMax Ultra 4.8V NiMH 2000mAh AA Receiver Flat Battery Pack
Weight: 122g (4.3oz)

HydriMax Ultra NiMH 6V 2000mAh Flat Receiver Battery Pack
Weight: 152g (5.4oz)

Hobbico HydriMax NiMH 4.8V 3600mAh Sub-C Receiver Pack

Makro has packs of 4 NimH "2700mah" for R179 odd. The Energizers "+-2000mah" were the same price. I like FB's idea of adding energy instead of lead for nose weight... to a point of course.

I will just install a std 4cell pre-built pack, thanks

No need to solder on to the batteries, just get a plastic battery holder at Builders w/house and solder your wires on to the terminals. I used 4 AA 2200mAh batteries (I think!) which cost around R180 including a charger! Gave me ample flight time

No way i would trust those holders, high-G turns will just push those springs down and possibly pop a battery out.

I feel the same about the battery holders. Donít trust them fully.
If you are going to solder tags or wire onto the battery just remember to use a large solder tip with high heat for a short time. Too much heat for a too long time will damage the batteries seal and reduce the capacity/output or damage the battery completely.
Here is another tip for soldering batteries: First clean the battery contacts with clean fine sanding paper and then use some kind of soldering past on the contacts. Tin the contacts first, then only solder the tags/ wire as described above
Use it donít use it

Fuzzy B,
I did this for years!!...never had a problem!!...just duck the cells with tape to keep them in place for those ""high G's"".....but like any aspect of this wonderfull hobby, preventative maintance will keep you safe!!

FB,
I like your thinking!!!....Those larger capacity packs would be my first option!!

Having some problems printing this out with Acrobat.
Can anyone help please?

When i print it out it is not as shown on screen. I have a border around the edge where it should be flush to edge (borderless). Page SCaling is set to NONE and I have unticked AUTO ROTATE AND CENTER.

What am i missing?

Borders

That's exactly what I got, but the dimensions are correct.
There are very few printers that can print right up to the edge.
I found that the over lap is about 1/4. I found the two that run together that have the 6 inch ruler on them, line them up with a straight edge, obviously with the inch markings on and build your sheets from there.
It's just like "Dot to Dot" then and join the lines up.
If you use really cheap A4 paper, you can see through to the lines below and just join them up. Even easier with all those "Flute" lines all over the place for reference.
I selotape all the seams back and front, total 15 minutes work.
Regards
Simon

Thanks Simon.
My printer does do bordless printing, but when I try bordless printing with normal A4 paper it gives me a message about smudging on the ends of the paper and other things... I'll go print out the other 2 sheets of plans now and see if the dimensions are ok.
Do you cut the edges with the borders? I was thinking of using a metal ruler and cutting these borders off so they match up as perfectly and then selotaping them.

I believe the borders are suppose to be there. Use scissors to cut up to the lines to get a perfect fit. it also allows a little overlap on the underside to keep the template stiff.

Rhys,
As Mig Man said, I leave them on but where you have a line to line up with the next sheet, I cut in a little at the line only. I leave the rest of the border alone so I have plenty of meat around it to tape up.
