0257, i have this pack OUTRAGE XPRX 2S1P 7.4V 2500mAH 96g, it is outrage's purpose built reciver pack.
I have been using outrage packs for about a year now and love em. Plus the guy at the end of my street is the australian distributor.
As for the bec im using a maxpro
Input voltage 7v - 42v ,2 - 10 cells Li polymer
Output current 4A cont / 6A burst
Output voltage 5v or 6v switchable
I havent found out what the current draw for the ignition module is yet so i may use two one for the servos and one for the ignition i see the bec you have is rated quite high.

As for the raidio gear im using spektrum DX6i,a AR6200 RX and 6 spektrum DS821 digital servos for flight controls. for the throttle i have a bunch of old hitec HS82MG's so one of those will do the job.

I have never seen better parameters of a li-po rx pack!!! Really very light for the capacity!!!

Lets go back to the Seagull GeeBee Z.
Has anybody flown it already? Does anybody know the flying and especially landing characteristics of this beast? [>:]

You'd figure there was more than 3 people on the planet who have purchased this GBZ, yet this is the only thread online...

Well i got about a third of the way through the build befor i had to go to work again for another week.
So far only a couple of minor issues with the landing gear, i got two left hand wheel pants not that it realy matters but in the instructions said there was supposed to be a left and right. I just had two mount them slightly diferent from each other. The next thing was two of the bracing wires were too short so ill have to find somthing to replace that. If you look at the instructions online you will know what i mean.

As with mounting the motor the pre drilled holes are of course in the wrong place so i have to fill those and redrill to suit the 26 cc gasser. might put an extra bit of ply behind the firewall to beef it up a tad.

The tail went together without a hitch.

all the control horns, pushrods and odds and sods look to be up to the job

So it looks like it should be a winner and so far im quite happy with the kit and it was much cheeper than the great planes R2.

GeeBee Ace,

What's your opinion of the structure? Could it handle a 28 to 40 cc gasser? The plane is beautiful!

Well you never realy know until you try it out. I think its up to it, if you were unsure you could beef it up a bit, you know filets in all the corners and stuff. i soaked all the inside of mine with thin CA and left it at that.
But if you look at 0257's posts thats what hes going for i think the wieght of it is the most important thing.
I was working on mounting the motor yesterday and found that i need to make up some 45mm stand offs to put the prop out where it should be. the wieght of my motor is 1150g and when it was out this far it made it nose heavy. if you look at the motor 0257's got its about 1.4kgs so he will have to add a bit of tail wieght to the model. but with a motor that size it aint gonna be a problem that suckers gonna go straight up!
If you diidnt want to add tail wieght you could bring the motor back a touch without any problems apart from it already being a rediculously short plane already.

All i have left to do now is mount the motor, throttle servo, cowling and batt pack oh and put the stickers on and im ready to fly.

Hi Guy's, I have been watching this thread with interest. I have two Gee Bee 'Y's, the Pacific Models 84" ones, one with a CRRC Pro 40i and the other with a Thor 45. I also have an old YT International Gee Bee R2 yet to be completed. I was thinking of fitting the 40 to it, will be interested to hear how the Seagull Z performs with this engine.

Man I had my mind set for a world models p-47 and a skyshark p-40. THIS HAS F'd THIS ALL UP. Now I have to decide about getting this one. [:@]. Here is a link. http://www.sussex-model-centre.co.uk...d.asp?id=27190. It probably will not come out to the USA for a while, kinda like the Ultimate biplane when it came out.
I'm surprised to hear this kit is not yet avaiable in the US, when I first saw it advertised I thought they were probably cashing in on Kermit Weeks' Gee Bee Zee https://www.fantasyofflight.com/store/index.asp?cid=9 and aiming for the American market. As my Grandson has the book and the T shirt I guess I'd better get the plane.

I have recived and gone through my kit and would have to agree with 0257 that it is great quality for the price. Its gonna look great.
I was gonna post pics similar to 0257 but he beat me to it so thanks for your trouble
Only things i though were a bit average was the wheel pants and wing fairings are made from a type of plastic so i hope i dont crash it as it will be a bit hard to patch it up nicely as you could with fibre glass. The cowl however is fibreglass.
I saw someone asked about stringer detail on the fusalage unfortunatly there is none as it is a built up from ply and compleatly sheeted in balsa to make it smooth. it does look to be very tough though on the up side.

The only other thing i dont like is that stupid pilot face would of much ratherd a pilot from the 30s



I dont think im gonna have time to build it for a while yet so hopefully 0257 will get a chance
Im interested in that motor you have what brand is it and how heavy is it?
It looks like a good option. i think electric is just too expensive an of course flying time will be short.
I agree about the Pilot, rather not have one at all.
Best thing to do with those plastic parts is to rough up the insides then give them a coat of wing skinning epoxy and a layer (or two) of medium weight g/f cloth. Keeps them flexible but adds considerable strength.

Hi guys,
as I am using a 40cc gas engine and I really dont want to add any additional weight , I have moved three servos to the tail. Elevator servos are mounted from both sides and the rudder servo from below. If I still cannot get the right CG without the additional weight I can move whole engine about 2cm back. And for sure I can manipulate with batteries. I will let you know with next progress

If you are using the CRRC Pro 40i how do you plan on slowing it down to land.

Hi guys,
my "Z" is nearly done I just have to solve the wires, I want to have wires from both sides, from the bottom and from the top of the wings too. My 40cc engine is on its place, elevator and rudder servos placed at the tail, gass tank at the CG and everything is balanced without any additional weight. The total weight without a propeller and Rx is 5500g, with a wooden prop it will be like 5600g so the wing loading will be around 100g/dm2.
I am not at home now but I plan to make and post some pictures on weekend. [8D]

"Gee bee ace" how does it look with your gee bee so far?

0257,

Did the plane already have pockets in the back for the servos, or did you modify?

Well i havent managed to finish mine yet. Back out at work for another two weeks then its my wedding day when i get home so i think it will be a while till i get back to it. And we will see how heavy the thumb becomes.
I am waiting for a few bits i needed due to converting it to gas (nitrile gromet for fuel tank, fuel line and the extended stand offs for the motor)
Apart from that i have pretty much built it as per the plans and it all went together fine. Not to sure what i think of the dummy engine its ok i supose but i think i will atempt to make it look a touch better paint ect.

The upper wing wires sound like a nice idea 0257 might look into that myself You could just make them hook onto the fuslage or something similar so its still easy to get the wing off.

Nice colection you got there Rodbriz

Im starting to think i should have gone for a bigger motor but i guess we will find out. I wonder if it will be able to harrier??[>:]

My new pits turned up the other day too so as you can imagine it sucks to be at work at the moment.

Lifer,
the pockets are not prebuilt, it has to be modified.
In fact, I didnt build my plane. My friend built it for me. He is very skilfull. I am just a pilot now. [8D]

I hope it goes well, some video would be wonderful. I have the same engine in a Gee Bee 'Y', If your Zee flies well on it I shall be severely tempted.

Well, first flight is done.
take off was very fast, the engine has power for unlimited verticals. After few meters it started to climb. I had to click several times the down trim to fly it straight. All the acrobatic manoeuvres were without problems, knife edge needed just a little rudder use. Anyway the model doesnt fly like on rails at all. I would compare the flight characteristics to Pitts byplane I used to fly.
Landing... that is another think. I got a side wind, not very strong but the conditions were not ideal. When I tried to land for the first time I slowly approached, the landing gear met the ground and whole plane did quite a large jump. So I used a full throtle and tried it again. Next time it looked better. When I touched the ground I made few little jumps, everythink looked good when suddenly whole plane fliped over its nose. Afterwards I found the landing gear broke in a place of weld joint. That was the reason why the plane fliped. The wheel covers are both cracked.
And the video, thats a story. My father brought a new videocamera with tripod to the field. He filmed every important moment. After the crash he found he flmed NOTHING, not a second of the flight. He was nervous as well and used a wrong button After that he was so self blaming I felt sorry for him
OK, my plan is to rebuild the landing gear with a slightly stronger wire. I am not sure if I can repair the wheel covering. And I try not to fly in a crosswind.

Well not a total victory then, thats just made me more nervous, thanks 0257[]
Well as my dad used to always say "back to the drawing board". [sm=75_75.gif]

Did you land on grass or a runway? do you think it would make much difference.

Better luck next time mate.
