She's done, got her finished this morning. It was basically done last night but I had to replace a stripped servo arm on the rudder. This is the tuffest plane I own hands down. I thought this plane was going to be destroyed, it hit the ground so hard! but it is stucturally very sound. This is one impressive ARF, SIG did an excelent job with it. I am very impressed with it. At 8.5lbs it is a 3-D monster it is very impressive when I fly it, I got alot of complements on it yesterday. Too bad I had to go and dumb thumb it.

Big Barry, Sorry that your thumbs got in the way of good flying. Mine have done that too.
The Mayhem is tough. Mine suffered some radio problems on the maiden flight and I was lucky to get it any where near the runway to bring it back in. It was coming in for the landing though and looking like I might make it and it turned upside down and went in from about 20ft. up. The only damage though was that it destroyed the cowl and caved in the top of the fwd fuse. It was an easy fix and looks great now. Nice plane for the money.

The weight and physical size would be the only concerns .

Hi Nashtm if you will go too www.scottellingson.com/brillelli and click on the custmer photos he has some pictures of planes with gassers on them.One is A Mayham if you want too look at one.Thought this my help good luck.

Woohoo! Finished mine the again with the rudder servo change and a much farther back cg. I love the way it flies now and the harrier landings are just a blast now. I am getting very close to 6" on the cg now.

Anyway, rc, how do you like the 16x4W prop on the 125? Have you tried the 16.5x5W? I may want a little more spool and was thinking about trying the 16x4W.

Hey Wxman, The 16x4w works just fine. I don't have anything to compare it too with plane and engine combo but I get good response with it, plenty of power. I flew yesterday but left the Mayhem at home. [&o] Yikes!

wxman

What kind of numbers are you turning on the 16x4W?

Yo Rob,
Can you send me those servo measurements when you get a minute? Thanks .

Oh, of course....... I thought I did. I'll resend them tonight. Sorry for the delay. Rob

Guys I need a little help. I'm trying to decide between this Sig 3D Mayhem and the new Seagull Edge 540 60???
This string has been going on for 2 years and I figured I could get some great advise here.

Thanks

Here's the dimensions and some pics. From the end of the tail (fuse) it's 6 3/4" and it's 3 3/4" down from the top of the fuse. Again, I'm sorry you didn't get them originally. Rob

Cyberwolf

My Feedback: (4)

That all depends on what type of flying you want to do .If thats the red & blue edge that seagull offers I had one and don't want another ,it didn't even make a good acrobat let alone 3-d type plane .While on the other hand the Mayhem will do either a great sport flier Acrobat etc. or a serious 3-D plane with the correct engine and setups.
Like I said if this is the edge i'm thinking of there's no comparison between the two.
My vote is for the Mayhem hands down .

Rob,
Thanks . Are those measurements to be from the rear and top of the servo case or from the output shaft? How did you mount the servo to the fusalage. Looks like a nice clean install and I'll be using Central's CF pushrods.

wxman

Anyone else experience a bunch of wing rock on harrier or high alpha moves? Any solution?

Cyberwolf

My Feedback: (4)

No I haven't had any wing rock or seen any of the symptoms your describing here in any of the Mayhems .Check your ailerons and see if you might have some down in them ,I used the gage they sent with the plane to set mine .Since I don't have any trouble with the mayhem but did have tons with the funtanna 40 I added spoiler ons and that seem to help matters considerably.
Good Luck .

[/quote] Yes, the dimesions are from the rear of the servo case and the top of the servo case. I didn't try to make a tray to put it in but just made some plywood strips and glued them to the insidc of the fuse. It's a little tedious to get them in there but not too bad really. Try using some needle nose pliers or forceps and stick them in with CA. I think I also added some 1/4" stock to beef it up. Rob

Wxman, I haven't tried the 16.5x5W yet. I need to order one and check it out. Thanks

Thanks. After reading this string the Mayhem sounds like the best plane for me. I plan to run a Saito 125 4s and Hitech HS 635 and Hs 645 servos and a 6 volt bat.

I have been flying R/C for only 18 months but have 900+ flights and Seven planes. I fly pattern, scale and some 3D with my Dave Patrick Ultimate 40. I think the Mayhem would be a good choice for the next step??

You'll never be sorry you got a Mayhem. Very nice airplane. Does the best flat spins/blender of any plane I've ever seen.

Good luck.

Thanks

Rob,
Got it, thanks a million . I have one of those larger APC props to try on the YS 110, so I'm also interested in how they perform as compared to a 16 X 6.

Hi

how much difference does 1.5 pounds make ???

As I stated earlier in the thread I want to put a MVVS 26cc gas motor in the Mayhem.

I estimate that if I go as light as possible with this setup it will come out at about 9 1/4 pounds.

How will I feel this in its flight ?
Is it simply too much or will I still have fun with it ?

Thanks

Barry Cazier

nashtm...

You will notice a big difference in the way the plane flys. 1.5 lbs is huge on this small of an airplane. I personally wouldn't add that much weight. It's such a nice plane I wouldn't want to change it that much.

However, that being said, the Mayhem has such a huge wing area that it would still be a pretty light wing loading. The F-90 weighs close to 10lbs and has less wing area. The Showtime weighs almost 9lbs and has a lot less wing area. The infamous EF Yak 68" weighs almost 9lbs and only has a bit of 900" wing area. My Velow has 965 and weighs 8lbs 14ozs.

So....The Mayhem may be the best choice for the small gas engine. It would be a 1/2 pound lighter than all of the above planes with that engine.

I just wouldn't do it because I think it's a glow engine plane.

Thanks
Barry

Hmmmm...

I am getting so tired of the glow goo - although I have had good service from them - I have a 91fx with 50 hrs running time and 1 dead stick ( due to me leaning it just a bit more!!) This is with a perry pump.
The Mayhem has just got sooo much wing that I think it will still fly well but I realise that it cannot be the same as when its light.

I will try and force myself to accept the fact that I should put a glow in it (I have a spare one)!!!

Thanks for your time.

Tim,
If you are not going to try gas, then what glow engine are you considering?
