This one added about 100g to it wrapping it in tape.  Wasn't too worried as it should still have enough wing loading to cope with it and I've seen others flying at well above this weight with no issues.  Weight kind of went up a bit as I've added a printed motor mount, printed undercarriage mount (including tail wheel mount) and printed wing mounting system.

Still balances fine with the 1000mah 3S in the nose in the "not power pod" I installed.

Only a test for this little cub though - and extra weight might come in handy if this bloody wind doesn't drop soon!!

Well, tonight it had a maiden!

First attempt didn't go so well though due to me having it over-propped a bit much and the thrust angle was a bit too extreme too resulting in some great high alpha that I didn't order but managed to ease it into the tall grass around the pitch so it was all good.
So, I gave it a bit of field adjustment with the knife and hot glue then went for a 9x6 APC-E style prop instead of the 10x5 APC gas prop.  So much sweeter this time and other than hoofing a bit much elevator on rotate, it flew really quite nicely and I was able to dial the throws in.  Was a little twitchy of the old arse at first though as there's no spar in this, only a foam core that forms a box section inside the wing!

The maiden went so well in fact that I had another go soon after the maiden and this time had enough confidence to just keep low and close for the passes.
The landing though on the second flight, that wasn't so good, but I think I found the stall speed 😃
However, it has survived the extreme high alpha landing from the first attempt and a shoddy second landing after maiden without taking damage so for now I'm calling this one a success I think!

So, here's the maiden flight of "EY".  So called due to it carrying the registration of G-BDEY which belongs to the British TV presenter Arthur Williams who is wheelchair bound and had his Cub converted to hand controls so he can still fly 🙂

Looks pretty similar to the way the box flew tonight. I like the EY touch, I enjoyed his program flying around Britain and the Mozzie documentary🙂
Wot, no Depron?

Little twitchy but looks great. Smooth landing just applied those brakes a little to much. 😉

Flight wise it was pretty good once the rates were dialled in.  Slight cross wind blowing over the trees but nothing it couldn't handle 🙂
Arthur's got the wing off his at the minute doing some spar replacement work and have been speaking to him quite a bit - he's a top bloke to chat with.
Might be heading down for a photo shoot with him once the wing's back on and it's air worthy.

Second flight was much better but I didn't video that one, but Tracy did on her camera so need to edit a few bits out before it can be uploaded.
Landing not so good second time around though but I have at least found the stall speed 😃
New 1400kv motor is on now though spinning the 9x6 prop.  Do have the option of the 10x5 but it really does cause some torque roll on take off with the rest of the plane being so light and quite small...

Second flight video.  Not bad for Tracy's first time at filming on a DSLR 🙂
More practice required though 😉

Nice flight , shame about the landing🙂

Does just show that this foam really can take a knock or two!

In total it fell over itself twice on the larger prop.  Once from torque rolling into a cartwheel on rotate and once from about 20 feet when I just had to cut the throttle and let it drop from it's prop hanging high alpha out of control trick.
Then had that tip stall on landing and it only has the slightest little ripple on the nose but nothing more.

I might go mad and make a loony tunes one next just to see how it handles some real punishment 😃

I have had the high alpha thing happen on the first flight of the box plane, I either go for a total loop or ease the throttle and dab down elevator to get it back on track.
I think my box plane is twitchy in pitch because of the shape of the aerofoil. It has a very sharp leading edge and it is very angular from the leading edge to the spar and then very straight to the trailing edge, not a smooth foil shape.

I had that split second "cut throttle and try and land in the long grass" or "punch it and it might end badly out of control" so I went for the former and stalled it in 😃
Bit of thrust angle tweaking settled it down lovely though for me - no more twitchiness and feels really nice and locked in.
The wing on this follows a pretty smooth set up and almost completely flat bottom other than the undercambered tips.

Think the short length on this helps with the stability too.  Even feels nice to rotate and takes very little elevator modulation to keep the tail steady until it's up to speed (which seems to take about 15 feet on grass, probably be about a yard on the runway!).

All great until the landing, kinda like mine 🙂

Which supplier are you using for that one Shadey?  Looks like the amazon listing I saw which is from Germany and £25 delivery which makes it a lot more expensive when you consider the price delivered comes to just shy of £115.  A big jump from the usual price despite how many planes I can get out of a box...

I can't seem to find anywhere that has substantial stocks at the minute at a suitable price and sheet size.  SLEC have some in but I can't see it lasting long...


yeah it’s Amazon I’m using as I cant find anything local that’s suitable other than foam board from hobbycraft store which is thinner, not as strong and more expensive than the depron I’m using, 
yes it is £115 total for 20 sheets which works out about £8 per plane ✈️ 😁

open to to suggestions of other types of foam to use in UK .?
Fly it like you Stole it [smile]

Give that stuff a go at B&Q - I'm impressed with it and way cheaper than depron from Amazon...
