thanks

Nigel,

You need advice from a club member or someone who knows what they are looking at.

But, as a rule if you have a set-up designed for 4.8v you may get away with 6.0v but I doubt it. It may be that your servos or gyro are only rated for 4.8v. Many are 6.0v but a fully charged 6.0v battery will show nearer 7.0v and that is a lot extra for 4.8v electronics to take.

So, the answer is - maybe. But as above, get help. (As per your other thread)

and was told I'd be better with a 6v one

Who told you that?

[Boggy]

if your tail servo is marked s9254 then definatley not! :-)

[Fishingmadman1]

The chap at Revolution Models in Warrington I told him the sservos its got gy401 tail servo is futaba s3151
others are s3003

[Telehandler]

Not sure on the s3151 but i think the s3003 are rated between 4.5 and 6 volts, i wouldnt use them in a heli though personally

[Andy from Sandy]

The S3151 servo could well go pop if you use a 6volt battery.

[Fishingmadman1]

Is there a bad reason for not using them with a hheli have I been sold a lemon heli

[Boggy]

the 3003 are very slow for a heli which is why he has probably suggested you move up to 6v (to speed them up a bit ) the 3151 will take 6v but is again not ideal as a tail servo.

Will it still fly with out doing any mad 3d flying

[Boggy]

yes it will fly.with those servo's you definatley wont be doing mad 3d!

[Telehandler]

They will get you hovering and some slow circuits ! there just a bog standard cheap servo but enough for you to learn the basics ! get some pics of the raptor up then we can all try and help you more

Dude, Seriously, Have you ever flown a heli ?

[Steve]

There shouldn't be anything much wrong with your heli - Raptor's are built like brick outhouses.

To reiterate what has already been said - join a local club urgently.

Also, before jumping in and just buying a new battery, ask a question on this forum like, "Which battery would you recommend for a Raptor 30?" From this, people will start to ask questions about the model, your flying style, the servos etc etc, and from the information gained, you will (a) start to learn how things interact with each other, and (b) after a number of replies to your original question, will be in the right position to buy the right product(s).

As for your 6V battery, you may well find that your tail servo will burn out pretty instantly at 6V, as many tail servos are only designed to run at 4.8V, so now that you have bought a 6V pack, you might like to consider a 4.8V step down device to go into the line for the servo. If you want to know for sure, try Googling 'S3151 spec' and you might be surprised at what you find out when you follow the link at the top of the search results to here - Futaba S3151 Servo Specifications and Reviews You might like to do the same with your S3003 servos as well.

Furthermore, you might like to investigate the different types of batteries and cell sizes, and their suitability in a RC helicopter. If your new 6V pack is made of AA size cells then you should take great care when using it, if at all. Research Sub-C size cells.

Good luck.

Steve the 3151 Isnt a tail servo! 4.8v will slow it to 0.21......?
