Well, I've taken the plunge and bought an aerobatic airplane for my son. The Edge has gotten great reviews and the price was right.
I'm planning on putting a Super Tigre 3000 up front side mounted. Does anyone have any experience with this combo? Is it too big? I'm planning on putting the elevator servo's in the tail hoping to help balance the beast up front. Would 2 standard JR 537's have enough torque to drive the elevators, or do I need something more powerful? I'm putting a Hitech 605 on the rudder in a "pull-pull".
Thanks

I think this combo maybye to big. We have plenty of guys at our field that have this plane with an O.S 1.60FX or an Saito 1.80 four stroke and have had plenty of power for unlimited verticle. And this is at high altitude

Definately the O.S. 1.60FX (w/o fuel inj.)with a Bisson Pitts. I have the H9 Matt Chapman CAP232. With this combination I added 0 weight and the plane balanced dead center CG. Oh yeah you'll probably want to swing an 18x10 prop and use 5% nitro. I know the manufacturers recomemdations but inside the cowl the engine really can heat up with a smaller prop. I would say that this is THE perfect combination for this airplane. good luck.

I have to agree with the OS160FX on this plane.I had this very same combo.Mine had unlimited vertical & power .I was swinging a 18x6N apc with 5% nitro.I think the engine you are thinking of installing on your edge will beat/stress the airframe to death in time.My opinion on the Edge is this,altho the motor provided plenty of punch for the plane,it didnt help the fact that the edge wasnt a good aerobatic plane-Mine was sloppy at everything.I expriemented with cq adjustments,throws & everything-nothing ever helped the fact that it simply flew aweful.The only thing mine did good was take off straight & true without hardly any rudder input.We had 3 guys here at my field including myself that owned H9 edge540's and all 3 of us were unhappy with its abilities and sold them.I sold mine after 15 vigorous attempts to get it to perform it's task .She never came around for me/us.It was a shame too cause the h9 edge was a pretty plane.I then bought a DP330L & GP- PW300-both of these turned out to be awesome planes & very happy with both of them-esp. the PW300.I have a Brison 3.2 on my pw300,started out with a moki210.Anyways good luck with your edge540 and hope all works out for you

do you guys know if cg is measured up side down on hangar 9 edge 540 , book calls 4.5 to 5 3/4 inches from leading edge at the fuselage any idea where and how cg in this plane measured

Thanks tony

I have a st3000 in a 4* 120, and at 12.5 pounds its just right! (invest in a good vibe mount)

Don't listen to the naysayers, this should be a good combination if the ST is a good runner. I am flying my Edge with a Moki 1.8 (same displacement as your ST) and I really like it. I don't know what is the problem back on the right coast but they do very well out here on the left coast. I put both elevator servos in the tail as you are planning to do and it balanced perfectly with no added weight (12 Lb. 8 Oz. all up). Had to cut out the cowl for the cylinder head and one small corner of the BCM muffler. Nobody who has seen it fly or flown it has complained about it being a sloppy flyer. Even with my limited experience I have no trouble flying a knife-edge figure eight with no Tx mixing used. Good luck with yours..... [8D][8D]

If you have the ST3000---bolt it up and use the sucker. Nothing wrong with a 1.80 (30cc) on this plane.

Side mounting it is a good idea. If you have carb problems- just get a $35 Perry carb and drop it in. Works perfectly.

I ran my ST3000 with several different props. A 20-6, also a 19-8 and an 18-10. Keep it proped at about 7000-7500RPM on the ground. The ST3000 likes to lug a bit and ST rates the max power at 7900RPM. I used 5% fuel in mine. Higher nitro content can lead to high engine temps and poor running.

I would recommend a better servo for the plane. The 537 are a bit on the low side for an aerobatic plane of this size. If you REALLY want it to handle nicely; try some 4131 or 4721 servos. They are coreless and high torque. You won't believe the difference a coreless servo makes in the way your plane will fly. It's a whole new world when you switch to coreless.

You might get away with the 537 servos IF you run a 6Volt pack-- but you'd be serioulsy pushing your luck with that servo. I wouldn't do it, myself.

You can get 4721 or 4131 servos for about $70 apiece and you will have the piece of mind that your servos are powerful enough for this plane. It really sucks when you loose a nice plane to a servo failure.
