Is it really possible to do “flips” ?
 

I have been doing “flips” in RealFlight G2. Is it possible to do flips with an actual R/C plane. Or stated another way, what does it take to do flips with an actual R/C plane. Let me elaborate a bit:

I downloaded some files from “The Unofficial G2 Swap Page” (http://zeus.rcwizard.com/fubar_hill/G2.htm). I downloaded a recording entitled “Christophe Paysant Le Roux Cap demo recording” In this recording the plane starts from the torque roll position (completely vertical) and quickly flips (nose over tail) and returns to the torque roll position (repeatedly and about a foot off the ground) – very impressive flying. I tried this with various planes – and I could not do it. At best, I got loops, not flips.

Then I downloaded the SIG Somethin' Extra file (Add-on 1 - based on Extra 300 - Charlie Cain). This model is awesome, flips and harriers – no problem (in fact, easy - perhaps too easy ). I sure hope the real plane flys like the G2 model.

Fly as vertical as possible, reduce the throttle until the plane stops climbing and actually begins to drop tail first, snap to full throttle and full elevator (up or down) and "presto" … the plane flips. Not very difficult, but really fun. You can do them forward or backwards.

Charlie set the model up with very high rates and pretty fast servos. So is this really possible with SIG Somethin' Extra. If so, perhaps I’ll be getting one (O.S. 46FX and 5 Hitec 605 servos look like all that is required). If not, is it realistically possible with any R/C plane. Please don’t tell me I need a 40% Carden with multiple digital servos all around and a 3W 150 engine.

Thanks,

yep...its possible
 

A friend of mine does waterfalls (flips) all the time.....Until its recent crash, a SIG 300XS was his fav...Had an FPE 2.6(?) on it for power, and set up with the CG back a bit, with 3D throws on the surfaces....

Man, that guy can fly....

Just remember that 9/10ths of the airplanes you fly on G2 do NOT fly like the real thing. People adjust the power, airframes, etc to make them fly much easier in the game and do things that the real ones can't do. Now on the other hand one can change the settings to make an airplane fly EXACTLY like his or her real airplane.

Can an SE do waterfalls? I don't know because I haven't seen or heard of one doing them but that doesn't mean it can't do it.

I haven't got my Sig Se to do Waterfalls even with flaperons (isnt that suppose to help?). At most I can get it flipped half way

Flips
 

It is possible. I saw a young man(age 12) doing flips with a profile Gee Bee a year ago.

No...don't be silly....you need a DA 150.

As much as i tried i could never get my Sig S.E. to waterfall. One day i decided to work on flat spins and the such and temporarily mounted a few ounces of lead to the tail making it very tail heavy. It did help with flat spins but i still could not get it to waterfall. It would just loop. This is with as much throw as i could get on the elevator. If your thinking of getting a Sig S.E. i think you should. Even though this one trick is not in its inventory,you will still love the way it flies. I sure loved mine.

like mini loops? sure...
 

Morris planes shouldn't have too much trouble accomplishing flips... is this what you're talkin about:

Mmmmm Waterfalls … so that’s what they are called. Thanks for all the responses, they were helpful. Ha, DA 150 – I actually got that joke.

Jsonin – yep that’s it. On the simulator I usually start from vertical, do a single forward rotation, and return to vertical (perhaps then do a single reverse rotation …). - like the Christophe Paysant Le Roux Cap demo recording. They guy in your clip does about successive 15 rotations in a row – impressive (I’ll be happy with just a single rotation).

I just love the way the SE model flies in G2, it hovers really nicely. I would love to have plane that flys like the G2 model. That Charlie guy (who made the G2 model) is a genius. I suspected that waterfalls are really difficult to do with an actual plane (i.e., difficult in getting the right set-up). Even in G2 the set-up has to be just right - if you adjust the parameters a bit (e.g., switch to a four stroke engine, slow the servos a down bit) no more waterfalls – just loops. Still might get a SE, I just like the plane. Looks like I have a ways to go before being able to set up a plane to do waterfalls.

I was actually wondering about the use of flaperons to improve the response from the plane. I was guessing they might help – but this was just a guess. Looks like Shortman has confirmed that you need more than just that on the SE. I need to get my radio plugged into G2 and try some of these mixes out.

From flying G2 I concluded that you need fast servos (with the killer control linkages to match), the correct throws and very fast throttle response. Although there are lot of other issues, I wonder how critical the type of plane is.

So far I can see that SIG 300XS and profile Gee Bee are waterfall capable (obviously in the hands of the right builder/pilot). The SIG 300XS is some serious hardware. It’s just too soon for me to be flying an expensive plane like that. I guess a profile fuselage plane (e.g., Morris Hobbies) is they way to go (I just like the looks of SE better than most profile type planes).

Yes you can do "flips" or "waterfalls'. I do them regularly. With both a fun fly Pizzaz and a 1.20 size, 10 lb. World Models Ultimate Bipe. You have to have your control throw on the elevator set with at least 45 degrees of throw, or more. It helps a lot if you have flaperons mixed with the elevator to go the opposite direction of the elevator in the manuver, also at very high control throws. I don't use flaperons on the Ultimate, only the Pizzaz.

You must enter the manuver at a very slow speed, nose really high. Picture the entry of the flip as a Harrier manuever. Keep a lot of engine power in reserve. When you are ready to try the "flip", add all your power and full down elevator at the same time. You will most likely need to correct the effect of engine/prop torque with rudder. As your plane comes up the back side of the flip, reduce power to allow you to come over the top nose high and slow, then start over.

DON'T try this at low altitudes until you rae really good at it. You can spin your plane in in a heartbeat!

Simulators are fun....but...
 

I recently "flew" a chopper...first time out on a simulater for a few minutes...until I ran it into some trees at the edge of the "field".

I'll bet anyone out there a twelver.....there's no way, shape, or form...that I could actually fly a heli for 5 minutes...right out of the box...with no practice, or instruction. Those sims. are great for whatever you would want to call it....but they seem a little forgiving and unrealistic to me. :(

ok is it called a waterfall if i can hover in the same position and be fliping CUZ my fazer can do that then i go it to a climbing flat spin?

This big goofy plane does EVERYTING, waterfall included. The elevator servos are nothing special. It has a huge amount of elevator surface area and a ridiculous amount of deflection . probably 70 degrees. The fuselage is sort of shot tooo, and I bet that helps.

It waterfalls for days. It will go rev after rev until you get bored or it blows way off the field.
