My BV 141 built from the Ziroli plans. The plan was reduced to 36" span & then the wings were stretched back to 41"
The fuselage & pod were made in a similar fashion to lost foam only they were hollowed out to be around 15mm thick & the foam was left in after glassing. The wing is balsa over foam with an RG14 wing section & covered in film. It's painted in Lifecolor acrylics with Tamiya clear.
700g AUW & loading around 16 1/2 oz per square foot.

Next is something to fly at the local slope (Wybung).

A P40 Kittyhawk built from the Paul Janssen plans. This one was built pretty much exactly to the plans.
It flies fairly well & is much more suited to the local slope.
Wingspan is 37" & it weighs around 780g.
Construction is foam core wing & fuselage sheeted in balsa & covered in film.

The MSF 2015 group build was a Chaos which is a sort of slope scale L39 designed & kitted by Jordan (Hamburglar on RcGroups).

A really nice kit & flies extremely well.
The best quality fiberglass fuselage I've ever seen. Mine is built with balsa sheeted foam cores & 4oz glass. Painted in Auto acrylic white & acrylic model paint for the trim. Hand cut decals.
Came out around 1kg & flies beautifully though mine was true to form & a bit nose heavy.

Next was a French Dewoitine 520 fighter in Bulgarian colours. This was a bit faster build but still pretty slow.
Based loosely on the Paul Janssens plan however his is all balsa & around 48" wingspan. Mine uses fiberglass over lost foam construction the same as the P51 with a 60 inch wingspan & an AUW of 2.3kg.

It was also maidened at MSF 2015 & also very nose heavy with the CG at MAC 27%.
This one however, was very prone to hyper stalling the tail & had to be flown very carefully. It flew well but to much elevator resulted in a nasty roll onto it's back.
It managed 3 or 4 flights at MSF before I damaged the tail on landing. It'll be repaired shortly & will also fly with a more rearward CG at MSF 2016.

I'm sitting here with not a lot to do & thought I'd put a few pics of my builds up here.

The P51 was my first real PSS project & took just over 12 months to finish. It took that long as I was learning as I went, I have a fairly busy life so can't devote large amounts of time to building, but mainly because I'm a slow builder.
It's built using fiberglass over a lost foam plug & 0.4mm ply sheeted foam core wings. Based very loosely on the Paul Janssen 42" plan but only the rough outline remains with so many changes there is nothing the same. The wingspan is 60" & AUW is 2.7kg. It was maidened at Manilla Slope Fest 2015.
It was VERY nose heavy at 27% MAC so was zooming quite badly but otherwise flew well. Minor damage on landing & will fly with some fine tuning at MSF 2016.
