If you're looking at charging at the field in that kind of time, I'd use a single charger, do them one at a time at a 'one hour' charge rate. Any of the 4 button jobs should do it.

If you have a 12V supply capable of a few hundred mA, a 5W 40Ohm dropper resistor will get you around 150mA current into a nimh pack for trickle charging. Couldn't be simpler and is all I regularly use on nimhs*.

Overnight trickle charging also has the handy benefit of balancing the cells - something a one hour charger will not do.

* Barring an occasional capacity check done via a standard four button charger.

ok - thanks for clarifying jon

" 100/1 oil/ petrol....try that with your laser ( substituting methonal obviously)"

how much lubrication does the petrol itself count for?

methanol isn't lubricating at all, is it?

so would presume any glow fuel will always need more oil than an equivalent petrol engine?

The Tauri and Ugly Stick are definitely classics; the Ugly Stick, in particular, being much copied through the years, and even influencing such classics in their own right as the GWS Pico Stick; I bet that would have surprised Phil Kraft!

I think the Stik was something that would have been discovered eventually - no matter who discovered it.

It's the logical answer to "how simple can an all-wood RC airplane be?"

For simple, also read "quick to make".

Kraft's particular genius with the Stik was styling the tail end to look like a Fokker and plonking some big iron crosses on it smiley

As far as balsa builds go, this must be one of the simplest 20 size airframes I've ever been near. I've taken only three complete days at the workbench to get this far.

Major woodwork jobs left - fin/rudder, top rear sheeting, lipo tray and hatch. Then it is time for covering.

I'm going to leave the rudder servo until after covering, then I can figure where my balance is coming out and use the servo to adjust it a bit before fixing it in place. It is, like most of this build, out of the spares box, a mighty Hitec 300 - with ball bearings no less - in this case. I have an offcut of lightweight red sullivan snake, which is long enough (if needed) to get the servo right up against where the lipo will sit.

I keep thinking that one or other of the 40 (ish) two strokes I have, would go very nicely in a 48" version...

Wing bolts drilled and tapped. Reinforced the threads with thin cyano as ever after tapping.

This session saw the wing saddle fettled , the wing dowel fixed in place and the ply plate to spread the load from the bolts all sorted.

More to come...

Got a few jobs done tonight.

First one, added in some soft 1/4 to support the fin. Quite easy to fit when the rear fuselage is exactly a triangle without any slight bend in the sides.

Next up, blocks for the wing bolts, a chance to use up some more offcuts of ply (2 layers) and some balsa (1 layer) so solid that it has little other use in life. Also put in some more soft 1/4 wing saddle doublers as is common. 

Last, the tailskid is finished. Some 14g offcut stitched on to a piece of 4mm ply.

Not so very much more to do on the fuselage ☺

Thread: Cheaper or more expensive.

Why blame brexit? As Don says. Markets worldwide have already shaved 15% off the value of uk.

This is relative to the changes in value of euro land currency.

Studies of GDP and so on paint a similar picture.

18/01/2020 18:42:26

Lots of economic studies done on this.

It ain't gonna be cheaper.

Fancy selling any?

But. My understanding - perhaps wrong or oversimplified- too lean also means an advance in the ignition leading ultimately leading to pre detonation and high temperature?
