Hard enough to land at the start of the run way this plane is so slippery,, plan to try the flaperons tip ,, but i hear not so easy also..Someone mentioned adding fuel tubing to the wheels .. but HOW? .. also same person said add velcro..i forgot to ask him how??

So it has the wheel pants skirts,, maybe ill just put tubing in there.. or add to the axle hmmm any body got ideas?? thansk in advance,,

I have the 70" revolver with a saito 100 and i know what you mean about slippery . Just keep doing landings and soon you'll be able to land it in a short distance. are you landing on grass or pavement ?

Cut off a piece of fuel tubing about 1/8 inch. With the wheel on the axle, slip the tubing onto the axle and then compress it with the wheel retaining collar, and it acts like a friction brake.

Back in the days, I would just split a round servo grommet in half, and use one half on each side. They would hold a plane at idle power but let the wheel spin enough to take off and land without tipping over.

Dont know about the velcro, except to put a hole in a small piece and do the same thing as the tubing or grommet.

I'm not a plane guy so take it for what its worth...
I'm not familiar with the plane but I would guess by adding the fuzzy section of velcro to the inside of the wheel cowl so that it contacts the wheel and causes a small amount of drag to slow the speed. I wouldn't want to make it too tight though or it could push you into a nose dive when the wheels touch... I would guess they have been able to wrap the velcro from one side, around the top of the cowl, then back down the other side.

I would guess they may have glued a strip of fuel tubing along the ceiling of the cowl so that the wheel slightly compresses the tubing when installed. I'm not too sure of the clearance though. Again making sure that the tension on the wheel isn't so much as to make the plane preform a handstand upon touchdown.

Hi

I alway found the soft foam tires didn't roll as well as the rubber tires and seemed to slow the plane down.

The best trick is to learn to slow down in the air....

Regards
Paul

PS: this is a great Heli forum, you will get better plane advice somewhere else.

Awesome thanks all
Ok so i will start in baby steps... i will add the fuel tubing to the axle and try to match both sides tension wise so when it lands its straight...

Right now the plane has been down for a rebuild iam awaiting a new .46 electric motor... so nows the time to add wheel brake ideas... AWESOME . so i might add some velcrow to the top of the wheel pants after i try the fuel tubing tip.

iam going to be landing on grass to start if its cut short,, sometimes the grass gets caught up in the wheel pants... (Like to call it Skirts..lol car guy lingo.. )

So both asphalt and grass Landings...Thanks all for the help GREAT!!

i do try to slow down in the air as much as possible but for those who have flown a 60" inch Revolver knows slow on that plane is like 50 MPH..haha or so.. so its not easy to fly for me to slow..mainly a heli pilot to begin with but love planes also.. more relaxing..especially my t28 trojan,,oh what fun!! especially when your buddies have them also.. and race around..lol!!

Also, you mentioned flaperons. Again, back in the old days in pattern, I used to use the flaperon function on my Futaba radios to do just what you are hinting at. Aileron channel goes into ail pin, and flap goes (went) into into ch 6/aux 1. The radio had a flaperon mix, that could be turned on and off with a switch. I would use it to add about half flaps, and mix a slight amount of up ele to counteract the pitch changes.

We had an asphalt pad about 400 feet in diameter and trying to get a 10lb pattern ship to stop without running off the edge was a feat. The flaperons used to slow it down enough that it wasn't too hard.

BTW I still fly my Ugly Stik with the flaperons. When you use it in conjunction with elevator (like on control line stunt planes) it can really lead to some tight loops and other antics.

Flaperons
thanks about the flaperpons...the radio i have a Specktrum dx8 has a great built in program for it.. just as you mentioned it will add as much flap and elev as you want .

so position one is normal : then pos 2 i can add as much flaps as i want or half as much and also add a percentage of elev .
so to dial it right in.

then if i need more, i can set up more flaps and elev ..on pos 2. was told by few prople that did that same thing..is that the plane gets unstable.. difficult to land.. so i geuss just see for myself..you know baby steps.. etc.. ok thanks for the help this is a fun hobby and a great site..) cant wait to try ou the new tips from you guys..thanks again..yehaw!

Yeh for landing you don't need too much really to be effective. I use the center position as point 0, and if I go up on the switch, it couples the ailerons to the elevator - you actually get up flaps with down elevator and vice versa. Then in the bottom position, it drops the flaps like a conventional flap system for landing.

Flaperon
Which would be better to try first as far as flapperones goes: flaps(aileron) up and elev down.

Or flaps ailerons downs and Elevator up?. Adjust percentages. Accordingly..etc??

The flaperon wasn't a one way direction, you got both directions when you activated, but I suppose you could set the mix values in one direction to 0.

For you, I think I'd do the landing flap function first and slowly add in the flap travel until you get what you want. Just remember you will get some pitching with pure flap application so be ready for it when you apply them. Once you get control of the pitching, it will tell you how much ele to add to keep the plane stable when flaps are extended.

When you droop the ailerons you are changing the camber of the wing and it creates more lift. By creating more lift you are also creating more drag. The combination of more lift and drag will slow the plane down. Just remember to mix in a little down elevator when you droop the ailerons. You will have to play with the down elevator mix to get your approach speed right. By drooping the flaps you are changing the angle of attack of the wings. Another thing you might see is a greater tendency for tip stalls if you get the airplane too slow.

When you watch an airliner land, they appear to land rather flat. If they didn't use flaps they will have quite a dramatic flair at touch down. The wing has quite a bit of angle of attack but the fuselage is fairly level with flaps extended.

If you use flaperons, remember that your flair will not be as dramatic as without.

Hi

The main reason why airlines have flatter approach angles is they have slats.....

Go look at some of the regional jets that only have flaps, they come in quite nose up.

In an RC plane like the Revolver, don't waste your time with flaperons. I used to fly old 'jet style' pattern planes. These things are real rockets. You just need to learn to land.....

You said you were waiting for a new electric motor. Try a flatter pitch prop. It will give you much better braking. Does your ecs have a brake setting?

Try (up high) getting on the wrong side of the drag curve..... RC guys call it high alpha. With a reliable motor (electric in your case), you can fly really slow.

Paul

There are all sorts of ways to accomplish this and I agree with pwood. Spend some time and learn to land the plane.
Take it up high and learn the slow airspeed charateristics of the plane so you know what to expect when you get it slow.

I have tried the flaperons method and it works but is unneccessary. I think it's better to just make slow speed, high alpha approach (you probably fly the plane this way anyway, it's the purpose of 3D) the push the nose over when you get to about three feet and roll it onto the runway.

Yes, the last 2 posts is what to do, just dont stall tip the plane at low speeds ,go up high and learn how slow you can go. My 70" revolver can float amazingly slow for a heavy plane almost like a 90 size heli can auto rotate , Good luck !

++1 For Flaperons!!
I did this on my Revolver and it really does help you slow down nicely... I used about 30% flap and you could just barely see the elevator move when it was adjusted correctly..
For those saying learn how to land it, are not wrong, but these planes are VERY SLICK and CLEAN, a little help will not hurt you at all... go learn to fly your heli without a gyro... you don't need it... and that is the truth.. that is how I learned a LONG LONG time ago... no reason not to use that tools that you have available..
I never tried it at more then the 30% because that was enough to slow the plane enough and still have it stable on final...
Let me know if I can give you any more info on the set up...you will like it!!!

Good Luck, Stan

Make sure you are landing into the wind -and not going down wind :
I see it all the time

Slowing the plane
Greetings.. All of the suggestions, so far, might work out for you, but, here's another that will. You could go to (http://www.dubro.com), contact them, and ask if they still make their "Nose Wheel Brake" (part number 157). It has a spring that wraps around a steel drum that has little nubs that fit to your wheel spokes. I have Three (3) sets, that I purchased for use on my Jack Stafford kit, of an Alon Aircoupe. (I was going to put them on all of the wheels, and decided to not use them at all, since I land on a grass strip). The plane is almost finished, after sitting on the "back-burner", and I found the brakes in the box. I plane to use a Fox 50. (Still made in Ft. Smith, Ark, I love to buy American when I can). Good luck, what ever you do.

Success. Landing 59" revolver. ...but it's still fast..lol
So I tried the flapperones on 30% and added touch of down elevator..was bit touchy at first took several tries.. I finally decided to just practice my landings. Without it..because it was more stable with the flapperones off. So I practiced and its still fast ,,I need a lot of runway. I ran off it was and almost hit a car driving up to the field..ugh..
Then the wind changed direction,,as I tried to land with the new direction into the wind..it was 90degree to the runway. As I landed I forgot about the oncoming fence,,and bam..just bent the wing support bar. And put small dent in right wing,,I geuss I can fix that .. Thanks y'all
