RE: Airfoilz RCU Extra 260
Just bought the RCU version with Scorpion 2215-18 and 35A ESC. Plan to use APC 10x5E with Apogee 1500 LiMn. If anyone is using this motor let me know how it flies.

RE: Airfoilz RCU Extra 260
Nice power set-up...I have tried 5 different motors on the Extra now and the set-up you are using will give you great results. Are you setting your Extra up as an all out 3-D monster or are you going more for a pattern set-up etc? Hovers with your set-up is just a hair over 1/2 and will punch out at a tad over 3/4...with a good amount of kick! If this is your first Airfoilz build and you have any questions...just ask...I am here to help!
PS: Very fun plane!! Just go easy on the CA and epoxy! |
RE: Airfoilz RCU Extra 260
Thanks Bighead93, Glad to hear the 2215 has good power, I will be setting it up for 3D. I've been flying a Typhoon 3D for the last year with practice on G4. From what I've seen so far, the Extra should make the Typhoon feel like a brick! Can't Wait to get it built and flying! If everything works out I will take the system out of the Phoon and put it in another Extra or Edge 540 for my 12yr old Son. He can fly the Phoon but it's kinda twitchy and he doesn't like it that much, hoping a more precise plane will get him hooked on 3D.

RE: Airfoilz RCU Extra 260
Night and day comparing the Typhoon to the Extra 260! I too started my 3-D flying with the Typhoon…fun plane but yes…very twitchy. The Extra 260 is so smooth…cuts clean and tracks great! The Yak 54 full fuse is next on my list…but any of the Airfoilz profile planes will impress! If your son is just learning then I would lean more toward the Yak 54 or the Extra 260…more forgiving. The Edge 540 is a 3-Beast…spins and tumbles like nothing else made of foam I have ever flown…I am getting close to the same performance with the Extra 260…put again I have been flying my Edge 540 for almost a year…and the Extra 260 only the past month or so…especially with the crummy weather!
Take your time reading through the instructions and if you aren’t sure on a step or anything just drop a line here in the build thread…I have built 3 Extra 260…not hard at all…actually pretty fun for me! Have fun!:D |

Not much action on this thread. Hey bighead, did you ever put together the full fuselage Yak54?

RE: Airfoilz RCU Extra 260
Good, I have one myself, still in the box. I've been too busy lately to start on it. A build thread would be great and give me so motivation! Keep us posted, and let us know how she flys.

RE: Airfoilz RCU Extra 260
Help!! I just finished my Extra 260 Build and had its madien flight. Here are some problems I can't figure out. I have wing rocking in slower flight and harriers. Back and forth and back and forth. I drew a line at the end of the wing in the middle and did the same on the aileron to line it up straight. When I moved the CG back some it lessened but was still there. As far as slow flight. I read some people had this plane flying super slow. Mine would go slow but always a danger of a stall and some times it would roll left over. I trimmed it out and it would fly straight and true at lower speed and high speed but I was limited to hovers for 3D. I put in the 2 washers under the left side to give trust as per instructions and the plane is built straight. The motor I am using will hover and has enough power to pull out, but not scream out. As far as power I am running the BP A2217-9 Brushless Outrunner Motor (Similar to AXI Gold 2217/20) (No. of Cells: 2 - 3 Li-Poly, Kv: 950 RPM/V, Max Watts:200W, Weight: 73.4 g / 2.59 oz, Poles:14, Model Weight: 300 - 1000g / 10.5 - 35 oz.
Prop SF 10x4.7, 20AESC, 1500 3Cell Built plane came in at 25oz. with all equipment. I am used to my flat plate smaller Foamies so maybe I'm just being stupid and this slow speed stuff, but I read that some say it flys so slow the can walk behind it. Mine I need a track star. Its flying more like a pattern plane than my other 3D's. Should I trya differnt prop to work better. I have a Park 450, would that be a better motor? And why the wing rock? Any help will be appreciated. Thanks. RS |
RE: Airfoilz RCU Extra 260
I have the profile Yak and the Extra 260 and they both have wing rock in harrier and I think if you read you will find others have the same thing. I have the Bipe and that is a solid harrier. Not sure why the mono wings do that and the Bipe does not. Both mono wings appear to not have rock inverted. I can fly it as slow as a fast walk, but I am working the ailerons and rudder quite a bit. I found that putting the CG at like 4" to 4.25" made the extra hover much better and fly better 3D over all. Sounds like you are a little under powered with 200 watts. I have 200 watts in my Yak profile and it is only 19 oz AUW. I have almost 300 watts and mine is the same weight as yours.

RE: Airfoilz RCU Extra 260
Nice flying there Harry!
By the way, I am going to start a build thread on the New Airfoilz Full Fuse Yak-54 in the next couple of days! Stay tuned... |
RE: Airfoilz RCU Extra 260
I just built the Extra 260. When I opened the box and saw the 3mm foam, I tought it was going to be fragile. But after building it, I cann't beleive how strong it is. What a great tought out design!;):D Cann't wait to fly it.

RE: Airfoilz RCU Extra 260
So did you get out and fly it?
|
RE: Airfoilz RCU Extra 260
Oh, Yes I did!!:D 19oz. with out the battery. 10x4.7 slow apc prop hovers better then I usually do:D. Knife edge tucks a little to the landing gear. I Landed in some ruff turbulence, the grass grabbed the left wheel and spun it around over 90 degrees and dragged the right wing tip, just a little scuffed up.;)
Same thing happened with my Mini Funtana 2 years ago and shattered the stringers on the fuse, very fragile. I ended up sheeting the sides of the fuse with 1/16 in balas. I'm just comparing the strength of the AirfoilZ to the Funtana weight about the same, and the Airfoilz is larger as well. I'm very happy with it. Don |

RE: Airfoilz RCU Extra 260
ORIGINAL: bighead93 Great to hear!! Trying moving the CG back a hair...once you have the CG dialed in the Extra will Knife edge with very little input! Thanks, I'll do that. I switched props, from a10x4.7 apc sf prop to a 11x5.5 apc e prop on my efite 480 more speed and thrust.;) I'll pick up a 11x4.7 apc sf to see how it works. Don |
RE: Airfoilz RCU Extra 260
I'm thinking of getting into these "foamies" and I like the Airfoilz concept. I have some electric stuff setting (servos, 1000 mah batteries, a CC 25, and a Rimfire 35-30-950) and was wondering if ya'll think the Rimfire would be too much for one of these?
Thanks |
RE: Airfoilz RCU Extra 260
Your Rimfire 35-30 should work fine. I would try an 11x7 prop with at least an 1800 mah 3S pack. I've flown the Extra with over 350 watts.
|
RE: Airfoilz RCU Extra 260
How about a APC 12x6E with a 3-cell 2100 - 2200.
|
RE: Airfoilz RCU Extra 260
You could try it. Just check the amps. Should have lots of power, but top speed would be lower than with the 11x7 though. Depends on the flight characteristics you like. I like a little more top end for those really windy days.

RE: Airfoilz RCU Extra 260
I have built four different Airfoilz designs including the FF Yak54. Great designs, but IMO the FF is too heavy for the wing. The FF combination weights about 7 oz. more than the flat version and has the same wing. When I take out the FF, I will go back to the Airfoilz flat Yak54 which is perfect for me.
|
RE: Airfoilz RCU Extra 260
That is strange...my FF came out just about 1-2 ounces heavier. I like the feel of the FF in the air more than the profiles...I really like the all;)

When I put my FF Airfoilz in, I will not replace it or I may just sell it. I will buy the profile Yak for as long as they have them as it is one of my favorite planes. I really like the Bipe on the Torque 2818T/900 and would buy another one of those. I do like that the FF is a more stiff fuse but I have not found the right motor for it. I have not tried the Turnigy motors, maybe that is in the middle between the Hacker 20-20L and the Torque 1095. |
