Status: offline 		Hi Guys:

I have a version 1 Edge 540 that I picked up NIB last summer from a friend who did not assemble it since new. I got it to replace my first V1 Edge 540 which was a beautiful flyer. I lost the first one when the servo screw backed out on the left aileron enough to come off the post and jam itself after a turn, rolling it into a tree.

I dried off my tears and started looking for another one. An old flying buddy (we learned to fly RC together 35 years ago) who flies 40% IMAC planes had picked up this one, planing to put it together to fly when he wasn't going off to contests. Well he never got around to it, and when he heard about my mishap, offered me this one.

I took it off his hands, and assembled it, and managed to get in about 6 flights before the winter set in up here. It flew even better than my first one!! I was loving it!!

Took it out last weekend and for the first flight of the year, and on the first landing, I caught the tall grass on the edge of the runway. It was flying so slowly that it was barely moving, settling in for the landing. When the wheels hit the long grass, the whole front of the airplane folded up!!

I was so amazed at this that I was standing there with my mouth open, wondering what the hell happened!!

It didn't even break the prop!!, but the whole nose of the plane was folded up. When I got it home, I discovered that there was so little glue on the front area, it's a wonder the plane held together for as long as it did!!

Anybody else have this problem? As I said, my first one seemed to be OK, and I had it for over 400 flights. Only got 7 out of this one!!

What do you think, Tom? Was this common in version one?

Regards,

Dennis

Not common at all, and it's probable that glue joints had nothing to do with it.

That plane was designed with very strong landing gear, so strong in fact that in a hard landing or situation like yours where the gear is grabbed by a rut or weeds it had a tendency to transfer all the energy from the landing gear to the fuselage sides which then would break.

Later designs still have strong gear but not so strong that the fuselage is destroyed.

Is there a way to beef up the Fus side on the V-1 version? What do you recommend doing??

Hi Tom:

Thanks for the reply.

I don't think that there's any doubt that the glue joints were the main cause of the fuse coming apart. I'll have to get my camera back from my son to take some pics of the pieces.

The fuse came apart at the glue joints and the glue joints show no sign of having any glue on them. The pieces that hold the engine box were pretty well damaged (Broken up) but the formers all came apart on the glue lines, just like there was little to no glue present. I'll get my camera and take some pics , and you'll see what I mean. I have never yet been able to break a glue joint apart without some of the wood remaining on one of the pieces, (at least, not until now!).

I do agree that the strong gear may have had some bearing, but the rest of the nose fell apart!!. Incidentally, this was one of your Fibre gears, not the aluminum one.

Dennis

Pic 1&2 are the inside of the r/s engine box. Very little glue there on the break line.
Pic 3 is the landing gear plate. Again very little glue at the joint.
Pic 4 is the inside of the l/s fuse side looking from the top. Not much glue there.
Pic 5 is where the rear former is attached to the fuse. This is the piece that the engine box sides are keyed into and the wing tube sleeve is also glued to it.

First is of the inside of the r/s fuse side where the fuse is glued to the F1 former that has the pins for the fuse hatch.
Second is the outside of the r/s engine box piece. It and the other side were each broken into about 5 pieces. Note the lack of glue there as well.

Just trying to point out that some of these version 1 craft were not properly glued at the factory.

No problem, it is repairable. There was no other damage to the plane than the front end falling out.

As I stated, it didn't even break the prop. I just thought some of the guys would like to know.

I was under the impression that this was a support forum for people to note their problems.

I am not slamming your products! This is the second WH craft I've owned, and I think you have an excellent product at reasonable prices.

Sorry if I stepped out of bounds.

Dennis

Status: offline 		Although not precisely applicable to your situation, I noted with interest the reminder in each of the manuals of the WH products that I have bought (now 4; all 50cc a/c)- seemed like good advice (of course my piloting skills NEVER let the aircraft get anywhere near a long life) :

http://www.wildharerc.com/downloads/documents/generic-manual.pdf

"Firewall reinforcement — First, be sure the firewall is properly glued, this is one weak spot of assembly line construction. Set the fuselage on its side on an angle with the nose down. Put something under it, glue may drip. Dribble thin CA into the joint between the firewall and the motorbox side. Let it dry, then repeat until the wood will no longer absorb any Ca. Turn the fuse over and repeat. Next, do this if you are using a heavier engine. It’s a good idea to install triangle stock in the corners where the firewall meets the sides, also with epoxy, in the case where you may be using heavier engine....In general a drop or two of CA anywhere that wood meets wood is an aid to making your new plane last a long time and retain its value."

Status: offline 		My WH edge 540 (v1) has serious damage to the landing gear box and the two sides (due to a rough landing in bad weather). It is definitely repairable. Here are some pictures documenting the process.

Pic1: the broken engine box

Pic2: the new sides cut from the pattern traced from the original

Pic3: the new former behind the wing tube.
