I have heard that the plane will snap at full elevator. At what degrees does it stop doing it? I would like to perform harriers. Mine will have an OS 91fx on standard muffler and an APC 15x4W prop.

I've been reading that the Extra is sensitive to snapping with too much elevator. Are people setting up less throw than the recommended 35mm because of this or just dialing in plenty of expo?

I've got:

low rates 40%
- expo 30%

high rates 100%
- expo 60%

This is out of a Spektrum DX-7 so it will be oposite of a Futaba controller (JR is backwards)
- I.E. Futaba will be -40% to make it softer and JR or Spektrum will be positive 40%.

Don't overload the elevator or it will be snap-happy on you!!!! High speed snaps will make your heart fall faster than your plane will in a banked turn to the ground.[:'(] Almost happened to me![8D]. Also a rearward CG will help out as well with handling with this plane.

I've got Airtronics so I don't think those numbers correspond? So do you still have the recommended 35mm of throw on the elevator though?

thanks

Lots of elevator is needed for 3D type manouvers. Full elevator deflection is best left for very low air speeds. If you fully deflect at high speed then the angle of attack of the wing will be too high and the wing will stall (stop producing lift, start producing drag) This normally happens on one wing first causing the snap and then the spin in the direction of the stalled wing.

Hi
Just wondering If an ASP .91 FS will have enough power to go verticle with this plane?
Im new to RC Universe, this is my first post.

Thanks Mark

Hi Marrk
Welcome to RCU. You will find this forum very helpful and informative. I have the Phoenix Extra. I am powering it with a ST G90. I will be interested to see how yours flys with the ASP. I have to go away for work for a week so the plane is sitting on my bench 1/2 finished. Where did you get yours. I got mine off the net from Nitrodude for AU $195, bargain[8D]

Hi Mark, I'm powering mine with an ASP 120 FS and it struggles to pull verticle. The ASP is new and is still running in so it may get better with age. I would doubt that a 91 FS would pull it verticle but it would be fine for general pattern / mild 3D stuff.

Hey y'all,

I just picked up this Extra 330s to replace a Pacific Aeromodel Edge 540T that met an untimely end (actually, it is repairable, I think, I just needed an excuse to get something else ).

This seems like a pretty good model. I'm planning on flying it with a Saito 100 with Hitec 6635HBs on all the control surfaces. That'll give about 83oz/in of torque at 6V. That should be enough for this plane, no?

Took it out of the box and checked it out. Looks good on the top, but man is the gray on the bottom ugly! Doesn't seem like a good color for an object that will blend in with the sky at times, eh?

What's the general opinion on the hardware? I'm not sure about the pushrod set up. They seem a little over-engineered. I've used Central Hobbie's CF pushrods and linkages before and might again on this plane. Also, I've run into a problem fitting the wings onto the fuselage. The wing tube appears to be about 1/2 inch too long. I can't get both wings to go flush with the fuselage. I can get either one or the other or both will just be a little off (1/4-1/3 of an inch). Doesn't seem right. I could try to cut down the wing tube or get a carbon tube and cut it down to fit, but you'd think it would fit out of the box. Any easy fixes for this? Sorry for the basic question, but my Pac Aero is the only other wing tube plane I've had experience with and it went together fine.

It was mentioned before and I'll go search for it again after the post, but what fuel tanks are people using. The stock tank looks like 10oz and I'd rather have a little more flight time with a thirsty Saito. It's a tight fit in the tank compartment, but I suppose a Sullivan Flex Tank would fit in there...

Sorry for the disjointed post... too excited to proofread..

I used all the stock linkages. They are working fine. Upgraded the tank to a 14 oz du-bro. Slid in with a minor amount of wood shaved off the of the top area where it goes in. I had the same issue with the wing tube... I had to cut an 1/8" off. Not an issue anymore!

RVM

Is there enough room over the CG to put the fuel tank?

bjor

Hi Bus Driver. The saito 100 would be a good choice. I too had the same problem with the wing tube, but cutting it a bit shorter didn't help. It seems that either my wings or fuse are not straight edged where they join. I can close the gap in the rear of the wings, or in the front with respect to the fuse but not front and back. No matter what I've tried I still have a 3 mm gap. I found the servo push rods to be a little "over engineered" but I have used them with no problems. If weight is a major consideration then toss them in favour for a more conventional rod a Z bend. The fuel tank is decieving. Running an ASP 120 FS at full noise gives me 15 minutes. I was going to replace it, but 15 minutes is ample for me. I placed alternating red strips on my wing bottoms to assist with hiding a lot of the ugly grey and making it easier to see. Overall I'm really impressed with the build quality of this plane - and all for a really good price. If this is typical of Phoenix ARF's then I'm won over.

Hey bjor,

Sorry to hear about the wing tube as well. Fortunately, cutting mine down 1/4 inch or so with a hacksaw solved the problem and the wings slide on perfectly. Unfortunately, work has got in the way and I haven't had time to work any more on the plane, but it looks like it will go together fairly easily. I'll try out the stock tank and see how it runs. If I can fly 10min of mixed flying and have a couple oz left over for the pattern, I'll be happy. It's not like this thing will need full power much, anyway!

I'm thinking of striping the bottom, too, but haven't decided which color goes best with battleship gray wings and a blue fuselage......

I went a little on the wild side by putting a Thunder tiger 120 PRO in mine, talk about power to burn. It 3Ds like a champ but had to put a 20 ounce tank in her to get good time in the air. using 11kg servos all round. The motor was a bit tight to fit in but not too hard, the muffler fits like a glove. She prop hangs at half power using a 17" 6" APC prop. needed to do a bit of cutting to let the air move around the cowl properly.

RVM

What is the weight?

Furbydeath

6kg dry, thats 13.22 lb.

RVM

13.22lbs for a 64" wingspan plane?

Furbydeath

Hey, what can i say its fun. The plane did have a OS91FX in but the motor played up a lot and the 120 was close at hand......

RVM

I think you have your weight wrong. If this plane weighed 13lbs the OS 120 would barely be enough engine for even basic aerobatics... that and the plane would have to fly 100mph just to stay airborne.

Furbydeath

Not OS120 is a Thunder Tiger PRO 120, but will recheck weight, used bathroom scales last time to get weight.

jay350us

I found that a fish scale with pounds and ounces works great i just hook it through the spinner

jay350us

also you can secure the scale to a pole and hook it to the tail wheel with rope to get a measurment of how many pounds of thrust a given motor can achive with a spacific prop.

Furbydeath

I dont have a fishing scale trying to borrow one from a friend. But the others at the club felt that the combo i have would be around that weight. I had of the IMAC flyers take it for a spin. they liked it, cheap with lots of gogo.

I was planning to use a ST 90 in mine until a buddy sold me a ST G2300. Does anybody know how she might fly with this setup? should have oodles of power.
