Hi called SAS yesterday to order a Fusion 46 but it seem this model has been sent to that graveyard on the slope it is no more so after a chat with that nice Alan Head decided to order the new wildthing MH? seems it is the best wildthing yet the root chord has lost about 1" plus one or two other small changes i cannot remember so much info in one short chat i also got a short history about the birth of the Cygnus the one in my avatar there are i was told still some fusion 60s to be had so think i might get one.

If there is anything i should watch out for in my wildthing build i would be happy to hear from anyone who has built wildthing allready.

The instructions say to chop the mounting tags off the servo's. I didn't. I just cut slots in the wing to accept them. Worked ok and if I need to recover the servos they're not spoiled.

ive had one for about 6 weeks or so now , brilliant in light to mod wind.ifyou could , and i would if i was building it again put a ballast tube in . its too light for heavy winds

I guess it depends what you call "heavy winds"! I've flown mine loads of times in 30-35mph no problem. I know the guys who fly from the Orme fly in much heavier but I'm not sure thats my idea of fun.

Mine has been flying for 2 years now and is in need of a rebuild, so I've now grounded it and that is my next modelling task.

the fusion 46 has the same wing as the wildthing 46.

Maybe that's why the fusion has been stopped - they are too similar?

Me too, just a couple of slots avoids the need to butcher servos

I disagree Ben - as Alan himself says, ballast isnt necessary, mine has flown numerous times in 45mph and well over, and its fine without.

Cheers

The hard part is launching it wink (unless you have a helper) once its away mine penetrates a gale just fine as standard, no mods, no ballast. Allan does specifically say not to ballast it.

I do enjoy big wind but the thought of 'taping a load of lead' to a model is quite scary - if it hit someone the damage could be really nasty, just think of the kinetic energy in that piece of lead if it impacted on a downwind leg at what, 70mph?

Cheers

BALLAST NOT ADVISED FOR THE WILDTHINGS..... more down trim, plenty of down elevator, and practice.

Ballast will kill it, or worse, someone when arriving, and if the wind is too strong for her...then buy more toys more suited to high winds. 2P

Hi thanks to everyone for your answers as for the ballast v non ballast im all for no ballast but i respect others opinions if we all thought the same well this hobby would never advance.i have flown lots of wings/deltas and would rather fly without ballast if possible for me trim is the answer i have tried ballast in wings a couple of times and didnt like it the model has to fly fast or it can still fall out of the sky then there is the landing a couple of sites i fly seem to have a dead zone on the landing patch plenty of blow coming over the rocks to keep the model in the air until you get below 10 feet then you hit the dead zone no lift no blow it is easy with an unballasted model a sharp turn with the ailerons and you can drop the model below the blow into the dead zone opposite aileron to level the model and your on the deck just a little elevator at the last moment it allways works no matter how the wind is blowing but cannot do this with ballast in as once you hit the dead zone slap its down and if your lucky the ballast dont come through the model

seems ive gone of course a bit here sorry guys but most of my flying up untill now has been in good blows as could only fly when not working but now im retired can go when i choose and the wife loves it which really helps anyway my wildthing will be here tommorow so might not get on here for a day or so

Yep that's right. When I bought my Fusion AH said he was thinking about putting the Fusion wing on a Mk4 Wildthing and indeed subsequently did so. This meant that the only difference in the two was the shape of the fin so I suppose keeping both in production was then a bit pointless.

When i phoned to order the fusion 46 i was told no longer doing it because the root chord had been made smaller and it was found that this smaller chord wing flew better with the wildthing fin than it did with the fusion fin the reason being that the fin on the wildthing overhangs the rear of the wing giving more stability with the shorter chord at least thats what i seem to remember was said anyway im sure it will still fly ok also remember alan head saying no more mk4,mk5,ect he wont be using mk numbers any more so this new model is a wildthing mhs not sure about the s bit he did say it stands for mill hill something or other because that happens to be his local slope.

My only Tip is...
When you've applied the first layer of strapping tape, put the wing cores back into their blanks and put LOTS of weight (books?) On top over night. I say this because I Failed, in my enthusiasm, to do this and went straight onto the coloured tape stage only to find a couple of days later that the CW tape had lifted in places, not the end of the world but far from ideal!

I think the ballast, is a personal issue, mine currently has 90g on the nose but I'm going to incrementally remove this & trim out as I go, I have only had 2 outings to date the first in 20ish mph & had a ball, the second in 35 gusting 45 and was noticing some wing tip flutter in my more "high energy" manouvers, possibly down to a combination of the extra weight and the CW tape being not properly adhered.

Just my 2p!

When applying the tape , avoid pulling tight as this will buckle the wing.

I can't really see understand the instructions being so vehemently against ballast. I have flown the fusion 46 (the orginal) with a bit of ballast and it was absolultely fine. I would not ballast too far beyond say half it's flying weight, but I think it is fine, if done sensibly (i.e not a bit of a lead handing off it).

I didn't really agree with no covering the underside or joing the wing halfs after they were taped either to be honest (nor did I use the supplied copydex-esque glue come to think of it).

Down trimming is not the same as increasing the weight and is a less effiecent way to fly. If it was a simple as down trimming models there would be no such thing as ballast. (ditto for full size gliding). Agreed there are better models for high winds generally speaking.

Ballast isn't the same as weight required on the nose (or tail) to balance a model.

To be honest the key to getting a good wildthing (which will fly well in strong winds) is keeping the drag to a minimum with a clean, straight build. I have seen many zagis/wildies/etc at my local slope with covering having off, improperly balanced, and with trim to mask build errors. Use the wing beds and make sure the CW tape and other covering don't warp the model. They are a heck of a lot easier to fly and setup if built straight and true.

I am not suggesting you cannot build it straight I have just seen that many wonky epp models in my time sloping that I know what the effect is. The wildy/fusion isn't that easy to build dead straight, to be honest, because the spar doesn't extend to the tips and there is no drag spar the on trailiing edge (and the EPP is fairly flexible). That isn't a criticism - the amount of freash epp and correx control surfaces make the model what it is - pretty much indestructible.

I wouldn't worry too much about whether you are getting a fusion or a wildy mark whatever, but it straight, get the covering stuck down and balance it properly and it will fly very well.

I like 3m '77 spray to help CW tape stick to an epp wing.
