David, even before your convincing argument on the leading edges, I was sold on the idea of putting something there to even out the airflow, but I still appreciate the points you make. They will at some point go on :-)
Dangaras, I hear you, and I can tell you that I am a person that brings my plane in hot ALL the time.....regardless of wing loading, weight or otherwise...I do it because I like to fly them in, I also like a scale(ish) roll out if I can get one. Adding to that, if something is going awry on the approach, I have a better chance of going around if it is 'moving' than a plane that is porpoising in at just on stall speed. With this plane, I followed the same tactic I always do....as I cross the 'piano keys' or the 'numbers' as they call it, I tend to close down the throttle to almost a stop, and glide in, but this thing lost height VERY quickly, the props stopped instantly! I dunno if them stopping immediately had anything to do with it since a windmilling prop presents more of a surface 'disc' than a stopped prop...anyway, she touched down on mains, and still rolled out quite a way with her tail in the air, and then settled onto her tailwheel, so she had forward speed for sure. I will just be more wary of it next time, and wind the throttles back a little slower.
Remember too, that mine weighs in at a hefty 7.1 kg's which is on 15lbs, so she is tubby. My landing was flap-less and in hindsight I should have had just the first level of flap, as it did not affect flight characteristics the way full flap did, and I think that little extra lift would have minimised the abrupt altitude loss....I am glad I did not do a stall test, even with enough altitude, with that sort of result on landing, I fear that she might have gone into a spin, and not recovered! Not nterested in that problem.....I will keep her flying at all times.
David, with regards to the mixing of elevator into the flap settings, my Spektrum DX18 is more than capable of doing it, I just need to work out whether I want to do it as a part of the flight modes, or if I want to do it as a mix with flaps. Some people like flight modes to manage all settings because the trim settings change with the flight mode as well, so once it is set, all the trims act with it and there is no drama. But in this case, I am thinking with two stage flaps, I might increase the first flap mode a little, and see how she fares, if it is managable, then I might ignore the second stage altogether. None of the models I have ever flown have had (or needed in my opinion) flaps. But this one might need a tad.
I will get her set up how I want her, and then I am going to just enjoy flying her.
Thanks for all the tips and suggestions guys, alll appreciated and taken in the spirit with which they were intended.
P.S....Badazz.....good luck on the prep, hope to hear a successful maiden for you too, and that real soon!

RE: DeHavilland Mosquito - 
. 
As nice as it sounds, the thought of having to tune motors to be so close, the messiness, the possibility of a motor cutting out....are all reasons that I stepped away from nitro in the first place! Not an option. What I DO want to investigate, is the possibility of a sound unit with speakers to provide some proper twin merlin noise! I am going to look at cutting the bombay open, and installing the sound unit in there....there is sufficient room for it, and it will also allow me to neaten up all the wiring and what not. I need to do some calculation on the weight penalties, but I have some options for lightening things up elsewhere.....just no glow for me mate.
