This is a Pheonix models Extra 330S (60-90 Size) with a O.S. 91 FX. Power is Unlimited. Its like a rocket at 60% throttle (rich needle valve setting). Prop 13 x 8 (breaking in prop). 4 x 3001 (servos), 1x 645 MG hitec servo for rudder alongwith Dubro Heavy Duty and Extra Long Servo Arms. Fuel tank changed to 450 c.c. by MK. Wheels changed to rubber (GP) for low bounce.

After the pre flight checklists were done just pushed up on the throttle and went like a bullet. The only correction i had to give was one click on the right aileron. Comes in very hot for landings. DR rates and expos were

Low Rates
Ailerons : D/R 55% Expo -25%
Elevator : D/R 50% Expo -40%
Rudder : D/R 50% Expo -30%

High Rates
Ailerons : D/R 100% Expo -25%
Elevator : D/R 100% Expo -45%
Rudder : D/R 100% Expo -25%

Tracks very very straight and true. Rudder gives great Yaw withought banking. while coming in for landing its very stable and using rudder alone you can make it track the runway. Planning to change to 15 x 4 prop.

Whats your final weight with no fuel, I was looking at this bird too. I was thinking it would be perfect for a Saito 125.

Hi Mike

The weight came to just about 4200gms with a os91FX

Saito 125 will rock it

I am looking at getting this plane and putting my Tower .75 in it with a pitts. I used to have it on my Phoenix Extra .40 size and it was rediculous. I just was wondering if a .75 would be enough for it running a 13x6. What do you think Sid?

Hi wc524

You can put the engine on this plane but it would not be a cracker of a performer. The plane would definitely do your basic manouveres but you would be mostly shuffling between 80 to 100 percent of your throttle.

Well thats what i think. I could be wrong. As far as the plane flying goes it will fly. But maybe later on you could look for an upgrade.

What is your total flying weight with the OS .91?

My tower .75 is running pretty well so I may get the plane and upgrade the motor later, but I'm enjoying my new Wildhare Yak, and I'm slowly moving to gas, so maybe a BME .90 will be in order with their gas conversion.

I just hate carrying several different types of fuel to the field everytime I want to fly a different plane. Gas is the way I'm going, glow fuel is getting pretty costly especially when I'd be running at 80-100% throttle like you said.

Can you measure the tip, root and length of each wing panel? Also need to know how wide the fuse is to calculate the wing area? Thanks!

I purchased one of these with the intent of installing a TH-75 but became concerned about being under-powered after reading some of the posts.

Well, unless you want to hang on the prop all day this plane is a very capable sport flyer indeed. I do not intend to use it as a 3D plane. Sport flying was at half throttle most of the time, take-offs were short and simple as were landings. Don't worry about the "freight train" syndrom during landings mentioned in the forums unless you put on a heavy engine. A 14x4W prop will fly it just fine.

Setup: Used supplied hardware;

Dry weight: 7.1 lbs or 3220 gr. I left off the wheel and gear pants to save some weight.

CG: as recommended @ 120mm, no extra weight required, just be creative with your battery location.

Wing loading ~ 23oz/ft2 (don't let that scare you!)

Servos: all standard with ~43 oz-in torque

Engine: New TH-75 with stock muffler, APC 14x4W, 10800rpm, 7.4 lbs thrust (3356gr) at 6500 ft altitude in dry New Mexico air.

Get one and have fun...you will not regret it and you can always over-power later.

Hi

The super tigre 91 should be good enough power for the plane but just be a bit carefull when balancing the plane cause it could be a wee bit heavy so you could just move the engine a bit backward while balancing the plane.

I'll get you some pictures of the inside tonight. I got the plane as a present after my dad wrecked my Wildhare Yak....lol....(that's another discussion).

I have removed some weight from the plane already such as the cockpit area I removed the pilot figure and lightened the canopy.

I too like ATMYCABIN have a Tower .75 in the nose and I am going for a 3D plane. If I can get it to under 7 lbs. I'll be happy. It won't have much pullout from a hover, but at least it will be capable if the desire is there.

Any of you guys with the .91 done any lightening or did you just ad weight to counter the larger engine? Much help would be appreciated to see where some ideas about secret lightening spots.

The plane has got overkill radio euipment that I pulled out of my Yak:
- JR 8611A Pull Pull on Rudder
- Hitec 5945MG elevator halves
- Futaba 3010 High Torque on ailerons
-2800 mAh Li-Ion regulated to 6V


Can NEVER have too much power, but I'll do what I can with what I got. Will post pics tonight.

The Tower 75, and an OS91 fx weigh within an oz of each other, according to Tower's Website. I have done some lightning too. Removing the pilot, and canopy floor was worth almost 1.75 ozs, and removing some material from the tail fin fairing was worth just over .25 ozs. So those two together was worth 2 ozs so far. Still looking for more to remove, as I want this to be a 3D plane.


On a side note I really do appreciate some one measuring the wings for me! I went ahead and ordered one anyway but it would have been nice to know before making the purchase. I did measure mine, and came up with 831 sq inches of wing area in case anyone wants to know.

I am also planning on not using the wheel pants or gear fairings, (which are really nice) and will most likely cut out most of the bottom of the cowling. I don't see much else that can really be done to the plane to remove weight. It's actually pretty light as is.


Here's some pics of the assembly process. It will go together well, as I have some great supervision!

Nice pics Cap, I am going to try to maiden mine this weekend so I'll try to run it through the paces as well as my abilitly is.

On a side note finding room for my reciever and batter along with a voltage regulator was a B$#)^. I had to mount the throttle servo on a mount just behind the fuel tank slot. I balanced it and it is around 125mm+ so it's going to be on the tailheavy 3D side already.

Also I added my old 14 oz DuBro tank from my old Phoenix Extra .40 size, as well as replacing all the endlinks for the servos with 4-40 Quik-Links. I only kept the carbon rod connections and stock control horns.

What prop are you running on your engine Cap?

I think I am going to try a 15-4 wide to begin with. I usually only fly profiles, and 35% planes so this plane is a step down, and I am not sure just what prop I will end up with as I have not had a 91 2 stroke in years. I picked up the 91fx used, and I don't even have it yet. Will get it mounted as soon as it gets here.

I would really like to get a Saito 125 for this plane but if it turns out to be a flying turd I don't want to invest 320 bucks in an engine, when I picked up a slightly used 91 for cheap!


I am going to try and use as much of the stock hardware as possible. Gonna gorrilla glue the ends on the carbon pushrods, so hoefully they will stay on!

Here are a few pics. I don't know how much larger the silencer on the .91 is, but Tower's is huge so it should not be much more.

Do you think a pitts muffler will stay hidden in the cowl?

Yeh it will, I just didn't want to fool with making new blinds since getting to them inside would have been a P.I.T.A. Also, at the 45 degree angle my engine is completely enclosed.

It comes at a 45 degree angle for the mounts, and my old extra did not have a tunnel for the silencer.......therefore I had to get a pitts, but I don't get the same HP out of the pitts as I do the stock muffler which is lighter and less restrictive.

Default RE: Phoenix Extra 330S 60-90 Size

hello

My self and three of my mates have these phoenix extra 330s 60-90size all fitted with ASP .91 AII engines hitec and Jr radio gear
The problem we have is not in the flying of them but the landing. They come in ok untill you drop the power a bit and them the nose drops
a little (too nose heavey) so we have put about 50grams of lead on the tail.

When it comes time to land and drop the wheels onto our grass strip the model bounce like a bunny rabbit (fast and slow airspeed ) some times they can bounce that high that you could walk under it.We have tryed and are using dubro 2.5"low bounce wheels and the stock wheels with stock alumium U/C that come in the kit We have tryed offer flying sites thinking that it was our strip but they do the same thing every time.

If any body has the same problem that we have with all three models landing please let us know.

cheers
