I have a hanger 9 advance 40 and a T/F p-47 1/7 scale. I am thinking of converting the advance for flaperon use to help in learning to use standard flaps that are in my p-47. Would this idea work. I wouldn't hurt to much to lose the advance in a crash learning to use flaps,but the 4 months and $1,400 for the p-47..... OUCH ! Any Ideas I'M Listening. Thanks Big Bob

The Advance 40 is a full-span aileron plane?
Flaperons can be done with it, but..
Full-span flaperons can generate tip-stallls when the plane slows down.
Each airplane has its own way of flying, and you shouldn't expect too much similarly especially when the wing loadings will be different.
The flaps on the P-47 won't do create the tip-stall potential, but it too can be flown too slowly, which also results in a stall and crash.
If you split the ailerons on the Advance into seperate flaps and ailerons, you'd be ahead on the learning curve for the P-47.
The P-47 will still have different flight characteristics from the Advance in any event.

Full span control surfaces... use spoilerons instead of flaperons. Deflecting them upward instead of down kills lift... you use elevator to hold the nose up and the plane will sink about like a heavy warbird that doesn't have flaps.

Don't go overboard on the spoiler throw... 5 deg is a lot. Put it on a switch that can change the mix eliminating the spoiler function. Then you have the knob to dial in the amount desired... and can flip a switch to put the plane back to normal aileron mode.

Practice with them at altitude to get the "feel' for what happens.

You can play with the Flaperons the same way and youwill quickly see why they are a bad idea... Every stall will depart into a spin with flaps down. If you know its comming and have the switch to kill the flaps... you can save it. (given adequate altitude...)

You should do that the other way around...

Regular Flaps work Better and easier than Flapperons.

Thanks Tall Paul, FHHUBER, MinnFlyer. you all have some great ideas. I think I am going to split the ailerons and make std. flaps again thanks and happy flying.

I tried experimenting with flaperons on a low wing sports model. To be honest they did not make a lot of difference and really were not worth the time and effort. I would not go that way again, full flaps are probably easier to set up and will give you the desired result.

No matter what you do to that Advance 40, it's not gonna act like your P-47. I would leave the Advance as it is. When you are confident enough to fly your 47, just take it up to a decent altitude, slow it down to about 1/3 throttle and deploy the flaps. See how it responds and get used to how it handles at a safe altitude. NEVER deploy flaps on a new bird when on approach for the first time, they all act differently and you might not be able to recover. Chances are that you will need some flap to elevator mixing which can take a few trial and error flights to get it right. Most warbirds need a bit of down elevator with flaps but as I said, they're all a little different. You should plan on making your first few P-47 landings without flaps until you get things dialed in and are used to how it behaves. Landing a 1/7 scale warbird without flaps is usually no big deal, just don't try to slow it down to a crawl. A little head wind does well when landing without flaps.

Well... I wouldn't advise against using flaps if you have them.

I do agree, you should do your experimenting at a safe altitude.

Flaps are a huge safety item when making landings with a heavy airplane. (also when taking off) Just a small deflection can tame a tendency to tip-stall. (Flaps over up to 60% of the central span... not flaperons)

The standard deflection for a full scale P-51 is 7 deg flaps for take-off for just that reason. It has been proven that flaps on takeoff can slow the acceleration of the plane and can make it require more runway to lift the wheels... however its the resistance to tip-stall that makes them useful at low defletion angle.

Trying to land a full scale P-51 or Corsair with no flaps is asking for trouble. Either you land "hot" or you tip-stall and wreck it. The high speed landing isn't a great idea... they tend to want to "trip" and plant the prop in the pavement. (can be done... but you better be good to try it.)

The P-47 has some of the same characteristics which would make some flap deflection a good idea for increased tip-stall resistance. Practice slow flight high without flaps... then with small deflection, then with larger deflections... I would just about guarantee the most stable stall characteristics will be with 5 to 12 deg flaps.

Bark, it sounds like the P-47 isn't your 25th airplane..
I advise caution if you're relatively new.
Although the TF P-47 is probably a good plane, (there's none locally so I haven't seen any), there's a learning curve that goes with wing loading; higher wing loadings need more care at both ends of the flight.. takeoffs can be perilous if the plane isn't permitted to accelerate to a good speed before takeoff, and landings, with or without flaps will also need more airspeed than your Advance can fly at.
The P-47 is a major investment for you, so don't rush it.
There's a prolific scale builder locally who builds really wel, and flies really poorly, since he never has bothered to learn much more about flying than a 4-Star 40's flight envelope.
His scale planes seldom last 10 flights.
And he's immune to advice.
Once the P-47 does fly, take it cautiously, and it won't disappoint you.
The biggest safety factor is "keep the speed up".

Thinking on this some more. you might look into a .40 to .70 size scale aerobat, like an Extra or an Edge before the P-47... The enhanced performance and the higher wing loadings will acquaint you with the characteristics you'll encounter later.. Having aerobatic experience helps particularly in relieving some of the tension "unusual attitudes" can generate unexpectedly.
There's lots of ARFs for those types, reasonably inexpensive.

Thanks from all of you for your great advise. I will leave the advance alone(its a good sport flyer). I was at my club today and met a member thats been flying warbirds for years. He gave the same advise fly high and test a little at a time. He also said it would be a good idea to go up with an instructor(with warbird experience) and buddy box the first time up. We have one member that qualifies for this. So I think I got figured out. Instructor First , Then Fly high and take it a little at a time. Thanks for all the help guys You got me going the right direction. THANKS HAPPY FLYING

I have a low wing sport plane and always had to land hot because of its horrible low-speed characteristics. I converted it to have flaperons and it couldn't be more tame at low speeds. It has full wing length alierons on a symmetrical airfoil. It does not tip stall at low speeds either. I think that flaperons effect each plane differently. The only way to find out is to convert it and test them at a high altitude.
