Thank you. Paul, it is an own design so I have the only set of plans. So it's flown, and it's not bin worthy! Wind conditions were less than ideal with a 90 degree cross wind. In the air, the ailerons felt very nice, no trim required and good responsiveness. Basic aerobatics were easy. It did feel like the centre of gravity is too far back- a couple of times it tip stalled in the tighter turns. Fortunately it always recovered very quickly and positively with removal of elevator. Landing was way too fast knowing that the c of g was on the less stable side and that caused the undercarriage bolts to shear when it hit the long grass, but it did as I intended and therefore it is a simple 20 minute fix. Sorry no video I was alone, I will try to next time. I wasn't expecting perfection being a bespoke design, but I think there is promise since the controls did feel nice. It does seem to like flying with power on, probably due to the large fuselage. Once the C of G has been moved, which will hopefully increase the stability and stop the tip stalling, then I can make a better assessment of the low speed handling. I don't think the wind conditions helped either, especially on landing. All part of the development- the important thing is that I still have an airframe! Next flight should be better.

Thank you very much both of you. Airworthy. The canopy glue hasn't quite set (and I might put a black outline on it so it looks nicer) yet but it is strong enough. All systems are in and working, no weight required for the centre of gravity. I was worried about the all up weight when building it but it has turned out to feel quite lightweight which I am happy with. It's too blustery to fly today, but hopefully some time this week I will get a window. It's very enjoyable building a model that I have designed and hopefully the flight performance will be good. Building wise, next I have a Wot 4 Pro ARTF which will be a quickie (Saito 62 power), a small aeroplane that my younger brother designed which won't take long and my Brian Taylor Mustang which will be a long one.

Thank you very much Controls have been hinged using my usual method of pin hinges roughed and then glued in with PVA. All connected up now: I test ran the engine which was fine. I'll probably do the first few flights un-cowled for convenience.

Indeed there has been! I have been quite busy but nonetheless the covering is almost done now. Might put some Saito stickers on it to liven it up a bit. Apologies for the awful lighting... I'm going to mass balance the tail controls to reduce the servo load. Most of the weight is in the aeroplane now and pleasingly the centre of gravity is pretty much bang on and AUW is reasonable.
