The aileron error really smashed her right back - fuselage up to about 3/4 along wing seat. Only salvageable was really the cowl, motor mount and firewall.

So here goes :

The split balsa sides were doubled with 1/16th balsa facings and sanded back.

The Lite Ply is actually fruit box ply from local market !! 

Original weight was 2.2kg and then first crash when motor mount box failed ... repairs put her at 2.3kg. Where I don't have balsa sheet suitable ... I substituted the fruit box ply .. so now she's 2.4kg. But CoG is still spot on.

The thrust on 5S = over 3.3kg ... so with that big wing ... thrust ... she'll be good as gold !

On Wattflyer - I'm well known as one who just cannot 'bin' a crashed model. I thgink it may come from all those years of hours actually building models instead of just zapping a few factory completed sections together. Grew up with Frog ... Veron ... Kiel Kraft kits ... just to name a few.

My real saviour today - is the laser machine. Allied to a standard scanner - it makes the job so much easier. Draw round parts on paper ... scan ... clean up scan in Paint ... save as jpg ... import to laser and vector trace. My days of fret saws ... jewellers saws etc. are long gone. 

Now all I have to do is test fly her when weather sorts out.

Next UK visit (yes I shall bring Depron for those who want) ... I want to get an Acro Wot for my 15cc Gasoline RCGF .....

I definitely like the idea of the laser cutter.  If only I had room for one that would take a 1200x800 depron sheet 😃

Grey foam great but not so for white stuff 🙂 .

I'm looking at a 1400 x 1000 Laser machine to accompany my smaller 300 x 200 machine I have now. I have projects that call for at least 1000m length ...

I laser white depron often ... no problem at all ... in fact its fab the cut it does. Very fast and only needs very low power. 

The limitation on a laser > reflective, clear or pale opaque materials.

As long as the material does not reflect or pass the laser light through - it cuts ... white foam is non reflective ... 

When I'm going to cut a former or other piece and I want to test where on the bed / sizing etc. - I often take scrap piece of depron and do a fast cut to check before committing my limited supply of Lite Ply.

Did a run up on the balcony to test all before possible flight tomorrow ... ESC ran and then pulsed ... so that's 'goosed' ... replaced and she's good to go.

YES - I checked aileron direction !!!!

I use white foam as my protection for the bench, all my pieces lay on top of it . It gets melted slightly when I do the hotter cuts , but it doesn't go through the foam.

Sorry you have me a bit confused .... 

Inside my Laser ... I have the Honeycomb bed which I lay all materials on for cutting. 

Comparing numbers : (Very slow cutting speed is 1 ... fastest is 100 .... laser power levels virtually nothing at 5 ... full power at 99.9)

3mm ply will take a cutting speed of 5 and power level of at least 80 .... 

6mm white depron will take a cutting speed of over 60 and power level of 15 .... (in fact I usually leave on the ply power level and increase speed to about 80)

Cut is clean and accurate with no extra meltdown with a line width of 0.1mm

I'm 3D printing with the control computer at present ... but later I will do a demo cut video

Depends on the power of laser of course. For cutting depron on white foam you need at least 30-40W laser! Other lasers wit low powers will only slightly etch the foam but are great for wood engraving!

Still confused ... yes - my laser is the typical K40 machine with 40W .. but I never run it at full power even when cutting 4mm ply. The white depron is being cut at extremely low power levels ..... 

OK ...

Mine is just a little guy, does balsa ok but not plywood. 😉

Any online link so I can see what you are using ? I'm seriously interested to read up ... if you can cut Balsa ... I find it strange that Foam is not ?

I can well imagine that if you are cutting 'wood' on top of the foam - then the power of the beam by time its been expended getting through the wood would be very low ... 
What happens if you just try foam on its own without any wood etc on top ? Reason I ask is that if I cut foam with wood under ... I've done this so I get a marked wood template .... the foam at low power has cut clean - but the wood is barely marked .. like engraved.
