You will need powerful servo's on the head and tail. Most people use futaba 9206's so I suggest you at least equal the kg rating of this proven servo

Great looking EC.

The servo's you suggest for the swash are okay regarding the specs, the 8900 I would not use for the tail as this is not strong enough only 72 oz/in you could use the 8717 for the tail. The gyro's are fine.

What kind of fenstron you use and what is the weight of the helicopter?

Hi John,

I don't know of anyone who has used the SK360 on the Vario 4 blade head, but these EC's have a reputation for being very unstable and I can confirm that. Weight is your enemy too, so keep it as light as possible. I tried a Helitronix mixer with 2 x 401's at first, but that didn't help it was still very scary.
Eventually I moved to the Helicommand rigid and it has helped a lot, but the thing is still a real handful. Here is my first flight with the Helicommand http://www.youtube.com/watch?v=m-B7ICsN9rg

This is my EC and although it is not a comfortable machine to fly, I still love it!

Darrens,

If you switch the head for an OF head with their weighted blades and using you helicomand I am sure the flying will improved dramatically. I seen outstanding resuls with the OF setup and the SK 360 combination.

I personally flown a lot the Vario 2 bolt head and the OF.... and there night and day difference. I am currently flying the large Vario Lama turbine with the 3 blade head.... and that one doesn't need an electronic aid for stabilization.... she flies like a dream.

You have such a nice helo there that is a shame is not flying as good as she looks.

Regards,

Gonzalo

Yes, I understand that to be the case but unfortunately the OF head looks nothing like the real thing. The Vario one is quite scale like and that's why I have kept it

I agree with what Gonzalom has said, it's such a nice heli but is a shame it's not flying as good as she looks.

I have a Vario Bell 412 with the same rotor head and blades. I have the Helitronix mixer with a Futaba GY352-dual axis gyro. I had similar problems when I first started flying mine. It felt very unstable in the hover and in slow cruise (in ground affect). I new the mixer and gyro was set right as it felt allot nicer then without any stabilization. The best thing I did was send it up into a circuit to see how it really felt. I was amazed! It flew fine and was not unstable or a handful in flight. Ok the flying characteristics of the multi blader are different but very quickly you get used to them.

I suggest if the helicopter seems ok in the hover, try flying it in forward flight, or get someone who has flown multi blade helicopters before to do so. Remember to keep the dual rates down on the cyclic and the expo up if need be.

Cheers

Craig Anderson.

I have flew it in forward flight and it is manageable, but not nice. The build has come in at around 14kg which is heavy for this size of machine and I have had Dave Hollins (Vario UK) have a go at it and we think it is as good as it gets. The EC does have a real reputation for this and I know people such as Peter Wales have gone down the OF head route with great sucess, I have just decided to sacrifice some of the flight charecteristics in favour of a more scale looking head.

Darrens,

I think you can machine some parts to make the OF head looks so so close to what you have..... but it will fly like a dream with the OF + SK360 combination.

Craig,
Please put to sleep the GY 352 and use the SK 360. your 412 will fly like a dream in any conditions. I used for a while the heliutronix and Gy352..... in fact i was the first one to try this setup..... it works more or less OK.... I had it on my Bell 412 and Later on my Kiowa turbine.... but if you have some wind conditions.... OMG no way to try. Get the SK 360 and you will not need the helitronix either.

Regards,

Gonzalo

GONZALOM,

I have turbine 135 with OF 4 blade system using Helitronix and gyros, flies GREAT but not as great as my 230 with flybared head. I have new 360 in package, waiting for a home, was goijng to put it in my Vertol but after reading this post thinking of giving it a try in my 135. I have never used the SK360 so I have hesitations as I have heard of instances of helies turning over on the first run, etc probably due to a paremter error and would rather have mine in one piece flying the way it is then have it wrecked but maybe your parameter set would work in my 135 and lessen the chance of a mishap? What is the thoughts on this?

THANKS

Hi Turbinator,

I have not own a SK 360 yet but I have experienced the results from very close from some of my friends! Specifically one flying an OF 5 blade head on a Vario Hughes 500 with turbine. All I can tell you I have never seen a better flying multiblade system….. with wind, no wind you name it! flew like a dream with the SK 360. The owner and pilot of that helo is "Nick" and you can find him here at seattle_helo
(I hope is OK with you Nick).

The issues that you are referring.... I believe some people in the past fail to initialize the gyro as they suppose and went flying when the gyro was not given the green light.

My only current multiblade systems is the large Vario Lama with turbine and for that I don’t need any gyro…except for the tail rotor.. I have about 9ft rotor diam. and the dampening in the head is quite good….. but when is windy I don’t fly it…. perhaps I need the SK 360 for a windy conditions.

For my next multiblaade you bet I am putting one of those gyros.

Good luck,

Gonzalo

while that vario head conceals the grips better than the of head does, it still doesnt come close to scale looking. vario used to make a head that was very scale to that of the ec135 though, it had the blades to match. i think it was made to go with the smaller, no longer available 60 size ec135. it doesnt use the "blade mounted in grips" design but instead an integral design where the blade's pc rod/arm is part of the blade itself. a most unusual design.

Darren, i believe everyone here are so impressed by that EC135 of yours( myself included) that it saddens them to know you aren't enjoying its full potential capability of outstanding stability. i too have heard all good things about the sk360 and at the price, why not make a pleasant flier out of that bird?
if however, it is as uncomfortable to fly as you say, it sure didnt look it in the vid. you are obviously quite confident at the sticks

drive a rotary, fly a rotorcraft

Has anybody tried the SK360 with the Vario head? Gonzalom, you say it's the best thing for a multi blade head but what about a Vario head? I know from other posts they say the OF head doesn't require any stablisation? I'm curious to find out, as previously posted my Vario multi blade with Helitronix mixer and GY352 seems to fly well, or have i managed to "tame the beast" as they say.

Interesting all this new technology.

Cheers

Craig.
