Which 5-blade rotor head for 700E?
 
Hi,

I have just bought a new 700E mechanics and a Huges MD500 scale body to put it in. To make it nicer I want to put a 5 blade head on it :)

I have looked at a couple of options:
Sportsmoto: http://www.sportsmoto.co.uk/acatalog...rts.html#a3743
cnchelicopter (xmchobbies): http://www.cnchelicopter.com/servlet...ss-Head/Detail
Scaleflying.de: http://www.scaleflying.de/product_in...ny--700er.html

I have tried looking around but could not find many reviews of these. Have any of you tried them (maybe with a different number of blades) or can recommend something else? The Sportsmoto one seems really nice, but my biggest concern is that it might be a little overengineered.

Thanks for you help guys,
Anders

Anders, I have ordered the 4 bladed head from Sportsmoto to mine Eurocopter tiger, Really like the looks of it, especially the maingripbolts, dont know much about it but the price seems fair,gone try and evalute it,I have talked to Mark as it stated that the linkballs are not included but he said that everything is included exept
the pushrods,in case of the pushrods the existing one that comes with the trex are used.

Cheers
Jack

I just read a very positive review of the Sportsmoto head in Model Helicopter World (May 2012 issue), so I bougt it now :)
Found it on ebay (http://www.ebay.co.uk/itm/700-Scale-...item2c6621e788) from the same seller for 279 incl transportation to Denmark, so that seems a pretty good bargain.

I will give a little review myself once I get it.

Here are two high quality ones that are well worth considering:

metal blade grips:

or with Glass Reinforced Plastic blade grips:

Although I have only bought the 600 size rotor head, I also would give a recommendation for the Century head, either version. The one I have is very smooth and set up very easy. Good luck and take care.

I have never had a multiblade heli, but I also would recommend the Century rotor head as there are four of them at our local field and all perform very well.

you need to have look at the swash plate.
Servo and blade grips level are not on the same height, this will have the affect of a strange control.

Only as Info before your first flight.

see what you mean, in worst case changing the swashplate, but the head is superb..:)

Should not really give much problems, because the "inner ring" ball joints are in the same plane with the swash plate swivel point, so control movement of the blades will be evenly distributed all around the cyclic movement.

Only possible effect is, due to the "outer ring" ball links being below the swash plate swivel point, that ailleron or elevator commands will have a slight negative pitch movement as side effect, but that should not be too problematic.

With a four point control it micht cause some additional strain on the servo's however but as far as I can see, that is not the case here.

It would be different if the swash plate swivel point woild be lowered to the "outer ring" level: in that case cyclic movement would not be distributed evenly. But that is not the case either.
