Hey Pete,
Is warbirds only on Sunday? Want to get my Dora recertified but have a friend coming up this weekend so trying to plan out a small hole where I can duck out.
Thanks

Logan warbirds today. Mustang did not fly as it was leaking fuel everywhere. Another job.
4 flights on the corsair.
Dave recertified on his EMS Fw-190 Dora
kill markings applied to my P47.

Good one Dave!!!
Yeah I'm surprised the F4 driver did not lose it on his first flight. He obviously did nothing about the CG issue. Oh well another pile of foam.
At least I did something on the 47 today.

Hay Pete kill markings look good, and about the leaky fuel thing you gota use new tubing once and a while, and proper clamps
2of our guys fly the foamy corsairs and both had to add a bit of weight in the nose. and good for Dave getting resert on the dora.
Cheers Guys Bob T

yes mate was reasonable pleased with the result.
Fuel leak was the GP fill valve, it is about 8 years old! Replaced that and major leak vanished but it is still dripping from carb mouth (inverted engine). Tank is pressurised to about 10 psi via the rear pressure oulet on the engine to a kline regulator. think the regulator might be worn. Have ordered a new one and will fit and pressurise once it arrives. Fuel tubing is not that old, I replaced it all a while back. I use thin cable ties to clamp the tube.
I have added addtional nose weight to the Corsair, the by the book location is way too tail heavy and the location as per video is too nose heavy, now it is just right!!! Without any porridge.
Never any doubt on Dave getting recertified, he is good on the sticks. Wish my flying was as good.
cheers

I was not aware that you guys had to be certified , I thought it was the bird's that had to be certified.
Corsair's don't like tail heavy in any size and my T/F G/S like's to be 1/2 bubble nose heavy and if I get it to slow it still wants to snap to the left, just about have the redo on it done still waiting on a new muffler to finish the cowl and then put it all back together, progress on it has been about like your 47 slow to many irons in the fire.

Pete re the Kline regulator, you probably only need to replace the diaphram. It is out of a walbro carb. I am surprised you got that long out of it, the diaphrams are designed for petrol not methanol so don't last forever. Bloody good gadgets though, I have used them on few models.

RE: model Certifications
The model is certified to be safe to fly the range of maneuvers that you elect to do with it in consultation with the inspector, and then the pilot is certified to fly that model and those maneuvers as well, i.e. why the inspector must be present at the first flight and confirm that they are competent to do so. But say Pete wanted to fly my Dora or one of my other models? he can do so long as I am standing there with him. If he was going to take her to an event were I wouldn't be present. he would then need to be certified on the model as well. The reality is that 95% of the time most owners/certified pilots are not all that far from their models so the rule isn't really that restrictive....
To be totally honest, I think our system is easy going, but with my full sized background in mind, I really like the German certification system where you have to physically prove structural integrity before the first flight. This can and does cause problems and lets be honest, I'd hate to deal with it, but it is a very robust system of certification.
Thanks
Dave

Dave have read the German rules, and they would be a PITA hear as well as most modelers would not have a clue on how to do the numbers if they did miner structural changes, But then again I have not done a math problem in the last 20=years except to add/subtract $$$ from the c/a

think I would have to go drag out my old engineering maths book and brush up on calculus and trig eeeeek
used to quite like euler equations of the form "e^j theta" and proving from first principles. 6 pages of calculus later . . . .
Don't ask me now as I would not have a clue!
we had this funny little Indian maths professor called Kash Dev who showed us all sorts of little shortcuts and tricks. Funny little bloke but man very switched on. Can still hear his voice . . . "we take e de power j theta . . ."

my grandson is doing math on his computer, that is the way it is I showed him my slide rule and he did not have a clue what it was, the way they teach math now. he is doing great in school all but his spelling guess he is taking after his grand paaaaa.

New Kline regulator should be at post office today to pick up and I'm hoping my new paint masks for the P47 as well.
Not that worried if the masks don't arrive this week as I have lots to do on the fuz, stars/bars, squadron code letters, D-day stripes and then the nomcleature or however you spell it. Few days work in all of that.
Stars/bars are a little tricks as they have to fit over the open interncooler doors. Outside mask is easy enough as it will straddle the doors pretty much but the white mask will need a bit of trimming to get it to sit over.
Hoping for a warm day on Sat so I can get stuck into it early.
cheers

Hay Pete
Good you are moving on with it, can't waite to see it on it's feet. managed to get mine re balanced and it is a bit nose heavy due to the steel plat I used for the soft mount, so had to drill it full of holes removed 1 lb 6 oz So now have to re check ( had my grand son run the # on his math program) hope they are close, got the bits for my 26 cc gaser and it is back in survice. finaly got the paint on the Corsair , so been a bussy bugger.

Bob,
yes mate I will be pleased to see it on it's feet as well. Been a looooong time coming this build.
Good you got the CG sorted out. I'm quite fond of the use of a slab of 1/4" steel plate to mount the engine too. It really soaks up vibration well. My Seafury uses that method. Another job I have to get that back in the air
You have been a budy codger, good on!! Keep you out of mischief and out of your wifes way!
cheers

Looks good Pete, now I am going to have to find masks for just the white as my Corsair is so close to the blue in the decals I have and I don't like the gloss of the decal, so I will paint the stars and bars,
Got my RCGF-62 back and in the Week's, it runs great just have to break it in a bit, and go fly it as soon as the wind give up a bit (been 25 to 30) so lots of shop time in between playing nurse for the misses as she broke 2 bone in a foot also got some new rings for my 28cc engine and now have it running and with my luck we will get an early fall
Cheers Bob T

Sorry tonhear ear about your wife's foot mate. That would be tough going on her. Mate of mine has a similar problem and it's driving him nuts.
Good of about the engines. I vetted the cline regulator in the mustang and the fuel leaks are fixed. Have not run it yet though.
Last mask for the fuz. But of primer on then I'll spray some white.

Not sure I posted this earlier but my Landrover Discovery blew up the engine last Friday, about 1/2 km from home. Had to get a tilt tray truck to come and pick it up. $93 AUD!!
I suspected it was the timing belt tensioner bracket that had failed as they are a know weak spot, LR have put out an upgraded housing to cute the fault but when I had the timing belts done 18 months ago I did not get this housing done as it was another $1200.
The LR specialists have confirmed the engine is completely shot and needs a new one. Have to get some finance to cover it and if that is successful will be about 6 weeks before I have transport again.
So no flying for quite some time.
