Hey all,

I'm looking for an Edge 540. I was looking at either the new Goldberg 77" or the WH 25% 72". Anybody seen,flown or heard anything good,bad or otherwise especially the Goldberg 77" I'll be putting my Moki 1.8 in it. I have it in my old Midwest 80" Cap,and it flies awesome.. So I think it'll fly either very well..

Status: offline 		I am just finishing up a 77" Goldberg Edge 540. I have built several Goldberg kits over the years and found them to be excellent products. After a 5 or 6 year rest from R/C I decided to jump in again. My first choice was a Goldberg Super Chipmunk not realizing they were now a "new company" and the quality of the kit was not the same. With all the griping I did about the "new Goldberg" people were suprised that I bought their Edge. So far I am not disapointed. The construction is excellent, the covering is very good with only a few bubbles to be ironed out and some edges to be ironed down. I am not impressed in the painting, my cowling should have been rejected, the silver was messed up when they tried to repaint a couple of spots. The bands miss lining up on one side by allmost an 1/8". The paint is very easily chipped and there are spots on the cowling and the landing gear that are chipped. The wheel pants look pretty good but suspect they also will chip easily. I am useing a DA-50 and while fitting the cowl found that I needed to reduce the overall length of the motor and mounts by at least 1/4" to get the cowl to fit. Luckily a machinist at work was able to make 4 motor standoffs a quarter inch shorter. I also had to enlarge the hole in the firewall to clear the carb. It was also necessary to remove part of the bottom of the engine box to clear the Slimline smoke muffler. With all the carving I had to do on the engine box and firewall I re-inforced the box with fiberglas tape and epoxy.
I am useing all Futaba gear with S 9451's on all control surfaces except the rudder which has a S9152, throttle and ignition use standard servos.
As soon as I can get a couple of fuel dots I will finish plumbing up the fuel and smoke system, check the CG and go flying........keep you posted

Status: offline 		I have the WH Edge w/G-62 and the Goldberg Yak 54 w/G-45.......The Wild Hare is by far a better product in quality of construction, available hardware, and customer service.......... Anyone who has called Goldberg/Lanier customer service should understand.....

Status: offline 		The Edge is all done and it had it's first 2 flights yesterday. It has an empty weight of 18 lbs. 13 oz. I have about 7 1/2 lbs of gear in the plane so I think Goldbergs 12 1/2 to 13 1/2 # guestimate of flyimg weight is way off. I was able to get the C/G right just by moving batteries around. The inflight trim took only a couple of clicks up on the elevator. I am running a Zoar 22x 10 prop and at 6300 rpm I have 26# of thurst
The first flight was uneventful. About 5 mins. into the second flight we heard a strange noise so I landed the plane. I found some of the covering coming off leading edge the right wing. I went over the plane with an iron as the parts were taken out of the box, but I guess I missed a spot. There is not much overlap of the covering. The only other problem was that tail must have hit harder than it looked as tail steering was lost after the plane slowed. The tail wheel bracket is made out of aluminum and was bent enough that the springs lost tension.
When the covering is patched and a new tailwheel assy. installed I'll try again.
All in all I'm pretty satisfied with Edge. I would give it a "9" for construction and a "5" for finish. It is more plane than I am used to, but in the long run is going to be fun airplane.

Status: offline 		My friend is away at college. He has a guy in his club there and he has a Edge. He had a real bad case of aileron flutter with 2 high powered servos an all his linkage was all correct on his Ailerons. I'm pretty sure it got totalled on it's first few flights. So just make sure you keep your throttle management correct. keep it slow on the downlines no high speed dives and you should be ok..

Just to let you know!!

Good Luck with it....

Status: offline 		I am astounded a CG Edge,77 inch ,DA 50 and over 18 pounds weight.That is just all wrong. I have had my eye on this thing too,but even with a light engine it would weigh hefty? no? Almost all 50 cc gassers with 85 inches of wing weigh in at 16 pounds..???

Status: offline 		Your right, my Top Gun Edge at 78" span with a MVVS 45mag in it comes in at 15Lb 10onz that 18lb monster sounds like a snap roll waiting to happen with that wing loading.

Status: offline 		These are the specs. right off of the box: Wingspan 77", Overall length: 74", Wing Area: 1139 sq. in., Flying weight: 12.5 to 13.5 lbs. As I said my equipment added is about 7 1/2 lbs leaving an empty weight of about 11 1/4 lbs. I suppose I could weigh again using a different scale, however mine are new and I have no reason to doubt their accuracy. I think I will e-mail Goldberg and ask where they got their figures. That should be interesting !!

Status: offline 		Patzane,


In my original post on this plane I was complianing about the weight. I did call Goldberg and as expected they didn't know how it could be that heavy. I have flown the plane 3 times and it flies great. Last weekend when I tried a decending left turn to land it rolled sharply to the right. Luckily I was able to pull it out and came around to try it again. Same thing happened at almost the same spot. I decided on a downwind landing as the apporach was a little easier to make from that direction. I was able to take home a whole airplane!!

The tank that comes with the plane is/was 24oz. I fly about 10 to 12 mins. at a time useing about a third of a tank. I swaped the tank for a 16 oz. Also I swaped the heavy nicads and NMHD that I had for 2 Fromeco Peerless 2400 and regulators, one for ignition and one for the rec. I may put another 2400 in for the rec. if necessary.

The empty weight is now 16# 10 oz. and flying weight with the smaller tank is 17# 6oz. I hope to get flights in this weekend so I can report on any inprovements.

It would be interesting if a person was going to choose this plane would put it together with no equiptment and then weigh it. I have a Aeroworks 50cc Yak QB on order and I intend to do just that to see what the starting point is.
