Status: offline 		Bummer fmbettaguy, sorry for your loss. This string went dead for a while, I figured either everyone was flying or building. I got my new Aeroworks 540t in the air this weekend with the same ST 90 that was in the old one. This plane took it's maiden voyage with considerable rework since learning all the weakness of the last one. Three ply was ran from one third the wind saddle up and past the landing gear area. I also placed a 12oz Durbo tank in her and 3" rubbers on the ground. It balanced perfect with battery pack placed on the left side front corner of the wingsaddle. I reglued every joint possible as well. First flight was 68 degrees calm and sunny. Latterally balanced with three eights ounce lead on left wingtip and cg at 3" tripple checked. It broke ground in about twenty feet and rolled right briskly. It was little fun for the first couple of minutes wanting to roll and dive badly. Ending with about twelve clicks up elevator and seven clicks left aileron. It was hands off straight now so I did a few inside and outside loops, checked knife edge which held nicely then took her up for some spinning action. I was please so far so greased the grass with her after eight minutes. I don't see exactly why I need so much up elevator. Inverted it needs just a tad down imput so I don't think it's balance nor engine thrust line. After mechanically adjuting the trims and zeroing my computer Futaba it broke ground the second time in about fifty feet and climed very nice and realistic. I did mostly pattern maneuvers with some spins, snaps and edge work tossed in and greased the grass once again. I did not try any 3d or high alpha work wanting to make sure my engine is dead on first. The ST 90 can get about twelve minutes off my twelve ounces. Summary is the plane is fying well and seems pilot friendly. Next weekend I'll try some slow flight and see if any nasty habbits surface.

Status: offline 		I really like flying this plane. fly's as straight as an arrow. my cg is pretty far back but it doesn't fly like it. I have a 100 in mine and it ke loops well. tip spins are insane. did one yesterday were I gave it oposite rudder and it went into a sweet flat spin. blenders are very tight. it does upright flatspins that chase it's tail so quickly it's hilarious. it's not a floater, but if you know how to fly, and you have enough power the plane doesn't have to be. landings I can bring in pretty slow, especially in a little wind. it's also the best landing plane I've had. very good in the wind.

Status: offline 		I'm glad to see some fresh activity on this string. I talked to Rocco at Aeroworks and he states they fly with the cg back as far as 3.50,, I pushed my first 540 back to almost that point and it was very unstable and the wind simply turned it into a kite. On one prop hang it was pused back some thirty feet. That was a very hairly flight indeed. It has so much wing area and is so light I don't see it as a real friendly windy day plane. I moved the cg forward to about three and one eight and much prefered it closer to 3". I look forward to getting freaky with it this weekend and try out it's slow flight abilities too. The weather in KY is looking very promising for the weekend.

badfish,
That sounds great, I will keep that in mind. When I can find a free weekend I will definitely eMail you. It is always nice to get together with other fliers... I have been at NEPRCC for about a year so, so I don't know everyone real well yet but if I recall right, Billy has a lot of planes and a lot of LARGE planes, including Jets. He is an excellent flier, best I have ever seen in person. I only have seen him a few times at the field but he always puts on a show. Usually everyone stops what they are doing to watch... I am pretty sure this is the same Billy you are talking about. Cool, small world...

bodywerks,
A Saito 125 should be more than plenty of power for that plane, good luck... Can you explain to me how the altitude affects the plane's engine performance. Is it because of the lack of oxygen or air density for lift? Do you need to use more or less nitro because of this or doesn't it matter? Just curious, it really was never explained to me. Thanks...

Status: offline 		Lack of air density, period. It affects engine performance, prop performance, and wingloading.
Less air density means that air doesn't rush into the engine as vastly as at sealevel, plus there is less oxygen in it. Therefore you have a less dense air charge. This means you have to use less fuel to obtain a proper air/fuel combustion mixture, which means less total combustion energy. If that wasn't bad enough, the prop has less air to pull. It actually turns at about the same RPM as it would at sealevel because there is less of a load on it, but since it is pulling through less air, there's less thrust. Sucks.
It also affects wingloading, in that a given plane will fly heavier up here than it would at lower density altitudes. Up here, it has to fly faster and/or at a higher angle of attack to stay flying than it does at sealevel. Sucks, too! makes 3D that much harder...

I never realized how much it affects all aspects of the plane. Heck, if you moved down here you would probably have to readjust all your engines. I guess we are spoiled down here, stealing all of your O2 and living it up... he he he... Thanks for the explaination, it helps me now understand the affects.

Status: offline 		I was wondering, I don't remember if it has been mentioned in this post yet, but has anyone attempted putting a 90 2-Stroke in the Edge? I have been contemplating on putting a SuperTigre 90 in it instead of the Saito 100. What are everyone's opinion on this? Would it be too much for this plane? Would it have unlimited vertical? The ST90 is a 60 sized engine that has been bored out to be a 90 size. Please let me know. Thanks...

I have a Super Tigre 90 in my Aeroworks 540T. It's a power house and will deffinatly do 3D with authority. I have a 13/6APC on it now but on the first 540T I flew a 14/4 on it and it was an animal. It balanced GC perfectly with stock muffler putting the battery pack in the left front of the wing saddle by gluing in a quarter inch dowel rod to rubber band it down to. I did however beef up the sides with ply due to it's design weakness and added three inch rubber wheels which may or may not had an impact of battery location. Oh, also added a 12 oz tank to her. Cool Power 10 percent seems the fuel it likes the best having tried several that produced idel and transfer issues. The cool power makes it just hum. Your plane will probably weight out about six pounds flat like mine did. Good economical choice of engines with lots of power.

Thanks alot, how did the engine fit in the cowl? Do you need to cut much of the cowling? Do you have a pic of how you beefed up the sides? I have a 14oz tank I am going to throw in. Which prop do you prefer out of the 2 you tried?

The cowling cut outs needed are very minimal, an elongated 1/2" hole for the glow driver access and a 3/8 hole on top where the high throttle adjustment needs to extend out. The muffler will requier all of the "squared" section of the cowls underbelly to be drimmeled out 1/2" on either side and about 1/4" past the squared front. Dremel fiber cut off tool works great there. I did make a small 1/8 inch hole under the cowl nose to get a small screw driver up to the low speed adjustment. That's it, the engine head will be about 5/8" from the inside cowling wall and gets plenty of cooling. I access my fuel tube at the carburator with a pair of hemostats through the nose opening. I don't have pics but can some if needed. Also by a aluminium prop nut for starting, your 21/2 as supplied will explode and a larger one will stick up above the cowl.

Basically make paper templates of the side wall lightening cut outs at the forward parts of the wing saddle and forward of landing gear area and clue 1/16 balsa fillers in them. I cut out 1/8 x 1.5 wide slots between the sides and the ply wing jointer. Use the upgrade ply strengthening peices you should of recieved to use as templates to make new longer strengtheners that run from in front of the landing gear to back into the wing saddle over the doubler you glued into the lightening holes. You'll then need to use 1/2 inch basa or hard wood triangle peices to glue on front and back side of the ply wing jointers. Basically you fill in the lightening holes and run new ply from midway of the wing saddle all the way past the landing gear, shouldn't be too hard to visualize dispite my poor discription abilities. The upgrade stengthening they send still ends up being a basic butt joint in the leading wind/landing gear area.

I really liked the 14/4 W APC. The 13/6 APC needs more throttle managment on the down lines to avoid potential flutter. I fly mostly 1/2 throttle or less, useing power on the uplines or 3d escape and throttle back on downs.

Great! Thanks for the specifics... A couple things; You are saying get rid of the plastic spinner and get an aluminum spinner instead? Also, I think I understand but am not 100% of how you strengthened the plane. If you could send pix it would be great but don't kill yourself if it is gonna be a hassle. I appreciate your info. Thanks again...

I'm puttng my plane together right now and im getting pretty excited. I will put a saito 100 in it, from my Funtana s 90, and hope its as good as I a have read. I saw a guy at the field wit hthe Pacific Models edge and wonder if it is better. I hate second guessing my buy but some people say Aeroworks is better and others say PAcific Models. DID I MAKE THE RIGHT CHOICE? Also where should I have the CG,--3 inchs? im putting a Dubro 16 oz tank in it. I wonder IF It will be funner then the Funtana?

Snapped the fuse in half and put the landing gear through the wings. I was running an OS .61FX in it with an APC 13x4W and it was a real hoot. I've decided I want enough grunt for 3D. Any ideas how this plane will fly with a Saito .82 in it?

I was testing out the balance on the 540 tonight but it seems to be a little nose heavy with the battery in the front right hand corner. Now I am using a 5-Cell battery instead of the 4-cell. I can't see how I can put the battery any further back as the rudder pull lines would be in the way, unless I cut out the balsa bottom and make my own mount. Is there any other solution. I tried also to put the battery were the receiver would be and vise versa, it did seem to balance out a little better but I see most people say it should balance out at like 3 or 3 1/4. Mine is just balancing out at the recommended 2 3/4. What do yu think?

My battery is standard futaba, it's in the left front corner of the radio compartment looking from the rear toward the nose. I mounted the reciever in the battery location spot just in front of the rudder servo. This let me move the battey around more and it balanced latterally and CG in that spot. 2/34 CG is real conservative on this plane. Probably with your larger battery I'd relocate my reciever to the right side and as close the rudder servo as possible so you can scoot the batter back a little. It shouldn't take much to do that and just a little movement on that 7 cell should make a big difference in CG. You may need to CA a dowel under the tray to anchor some rubber bands too, you could use velcro also. The reciever is so litght it's movement won't have much impact and relocation should be easy. My strengthening on the sides got tested this weekend as a flame out on throttle transition over the runway left no choice but slip it onto a rough gravel road. It bent the landing gear some but the plane was unscaved. A new Perry carb is on it's way. I hope this is some help to you. Sounds like you are about ready to fly !

Yeah, I had already put the battery to where the receiver normally would go as close to the rudder servo as possible and put the receiver in front of it but I only CG at a hair more than 2 3/4!QUOT! I am getting in a MACS muffler for the ST G-90, hopefully that will lighten up the front some and give me some more breathing room for the CG. I may just, as I said before, cut out the balsa under the rudder cables and make a new shelf for the battery to sit on, that should definitely do it. It is a 5-Cell 6V battery, not that much heavier than the standard but it does make a difference. I didn't strengthen up the sides as of yet. I ran the engine in this weekend and one of the dowels in the canopy cover came loose and fell out. Now I have to find a new dowel to stick in there. After seeing that happen, I am a little leery about this plane's integrity. I may go over everything with some CA and maybe throw in the side wall reenforcement something like you did. That engine has lots of power from what I can see and I don't think the few extra oz. of weight will matter. I am going to work on it this week. How did your plane fly? Do you have any pix or video? I would love to see!

The macs muffler should put you right where you want to be with CG. Deffinatly go over each joint with CA. The stringers on the underbelly have had several joints come loose on my first 540 from Aeroworks. I went over every joint made on this second one, along with strenghting the sides. Sorry, but I use a computer all day at work and don't have a home pc, so posting pics are something I normally don't play with but would help in this instance I'm sure. If you Can recieve a fax I could draw a quick diagram. The canopy dowels were not glued at all on the second plane.
My plane flies great. So far my only trouble is the G90 flaming out in transition, the Perry carb will fix that though. Super Tigres spray bar set up has always been an issue, they just won't transition and in a slow flyby that spells disaster. Without the side strengthing I'm positive the plane would of snapped in have at the leading edge just like my last one and many others. I'd say don't fly it with out strengthing it. Once that is done, have confidence in the plane, it's a super preformer.
