Hi Jim!  Thanks for the pic or your  20"  Wildcat.   Smiley   It looks like you have the rear motor peg moved forward one bay  -  just like your other  models in Reply #1242.   That really seems to be the key, for easier trimming and flying, as I have recently found out myself ...!    Wink    I would say good luck with the trimming flights, but yours all seem to fly great (with out any "luck")  Cheesy

A new Coupe, devoid of anything innovative or clever. It's essentially a Baron Knight but everything thinned down to reduce drag, including the section. Weighs 73g - no beacon yet.
Well it's now ready to go, with every hook, band, screw etc, and the weight has ballooned to 78g which is quite disheartening. I have no idea how to remedy it next time. Lots of models have these carbon booms, the tailplane and fin are about 4g so there is no room for reducing there, and yet the wing is now much further back than I expected for a 60% CG.
The 70g airframe weight of course was set when all a model carried was a piece of fuse. Is it attainable now, with timer/rdt and beacons? I remember J O'D telling me that most models trumpeted as 70g were in fact well over that when everything was on.
No more carbon booms for me - I'll go to a rolled balsa boom, and it may also have to be a mylar wing.

Did you sand the carbon boom?  Other than that - CF/balsa structure, geodetic rib placement on wing and tail, mylar covering, just dust visibility paint on.  Alum hub rather than piano wire. Square cut tips rather than curves. 

Keep at it - practice makes perfect.

When are both dates please? It's about time I brought my models out of retirement and flew them. Nice looking model by the way.

You just missed the Tatton Coupe event last Thursday.  Offer still open.

Hello Ralph, no I didn't sand the boom. Is that normal practice? Doesn't sound healthy!
I'll try again next year. Scale models to build.

Thanks Ralph I've moved back down to the East Midlands. Better health care treatment if you know what I mean. I'm still flying, mainly rc electric glider but must fly my coupe's soon. I have too many!

Hi Bill, I have every intention of making the 2nd of December. Do you fancy a swap? The Coupe in the picture the one on the right all wood, the timer isn't how I like it to be honest but it works perfectly. VIT and DT and a terrific climb. BE airfoils and Wobeck tailplane. It's brand new as such not trimmed but I can do if you like, designed to go R/L and included is the prop hub complete, it's an Alex Bukin one 430mm prop blades,
designed for winding outside the model on 1/8th or 1/16th rubber, I prefer the latter on 24 strands. Total weight with tracker, not included, 71gms. I've to many of this coupe 4 in total so it'll never get flown really. Ivan T has seen them fly so hopefully he'll comment favourably

I'm rubbish at building scale and haven't really got the inclination to do so but really admire them. Maybe a rubber job that you no longer use? Doesn't have to be anything special.

Edit. Ive changed the Rudder to a fully symmetrical NACA 0008 as opposed to the one in the pic as they fly much better, mistake on my part when I built it I used my old plan.

Hello Tony. They look beautiful- I've only got two rubber scale models; I need one and don't bring the other out in daylight! To be honest, I can't get my head around flying other peoples' models; I even felt guilty about buying a boom off Woodhouse. I'll be interested to have a look and see how it's done. My wing is overlapping the peg.
A lot of duration flyers tell me they couldn't do scale but the truth is very much the opposite. The quality of top duration models, especially the systems, far exceeds any of my models, which are all smoke and mirrors.

Not a problem Bill, funny as I think building Coupes down to weight is quite easy wood ones at least carbon ones can weigh more normally mine are around 5% overweight. I'll show you one that I rarely fly as I daren't break it which is totally wrong but it is a complicated beast.

I'm always looking at your SE5A plan that looks a bit bigger than Doug McHards and think if I got rid of the sheeted sides did it boxed could it be done as a rubber model, but then I have no idea of what type of prop how much rubber how to rig it how to trim it and no idea which way they fly-most seems to go left that is totally alien to me! Oh and how to cover it and add scale detail all a black art

Think I saw it on You Tube and think he converted it to diesel? I've not seen him for ages hope he's keeping well and his models look brilliant. Loved the fact that when he flew F1B he made everything himself. I was his "checker offer" and calming voice he did the same when I flew Coupe

Well he should be at the Birmingham coupe -  I hope so; he picks my air!
Yes he converted it to diesel but as rubber, it scored 10/10 across the board on flying at his first Nats
