can almost every heli be setup for -10 / +10 pitch?

[FuturaSE]

Iv tried this to do with my Nexus30 but i cannot make this work

at this moment its -5 / +10 which is ofcourse good enough for me

however if i would change it ( i tried ) and start with pitch zero at midstick the most i can get is - 7.5 / + 7.5

seems the blades can only have a max pitch difference of 15 degrees
Iv tried but the output from swashplate on rotorshaft is definitly set to max both ways

I can believe this -10 / +10 will not work on a Nexus 30 however i remember in the early days i also could not set my futura se to this -10/+10


I need to try again this setup on my futura se this week and will let you know where i get stuck again, grtz

Don't think a nexus will give you + and - 10 if I recall.

I think you'll find -7 + 8/9 is more likely

If i remember to when I had my Nexus, thats right -5 and +10 sport flying, not a 3d setup. Will be fine to fly with aslong as you dont want to do a great deal of inverted Just set centre stick to 0 so it flies like any other heli

[FuturaSE]

ok tx that does clear up my mind no tic tocs ever with a nexus 30

You can definitely get +/- 10 degrees on the Futura SE, no problem.

Have you got a good quality photo of the head?

It must be possible to do some skullduggery (read: simple mechanical alterations) to get a bit more pitch range.

However, it's only a 30 size model, so you will always lack power. But on the plus side - if you can do it with a 30, then you will learn great collective management which will set you up in a great position going forwards.

I've seen a guy fly a Raptor 30 with an OS32 engine pretty well with lots of inverted, backwards and continuous elevator flips at about 6 feet in a howling gale.

[KevDavies]

Yeah you can steve. IIRC the mixing arms have two hole positions and just needs the balls swapping but it goes from stable to super twitchy. Best leave as is imo, and just not worry about inverted. They swing funny size blades too IIRC 525 I think and only come in woodies so i wouldnt wanna be 3d-ing it anyway

[Steve]

Swap the balls to the increased throw position and then add heavier paddles or flybar weights etc - easy compromise. Blade length is no bother - 500mm is a 'standard' 30 size blade and these are available in glass and carbon no problem.

If it gives you +/- 9 deg then it's a good improvement. You might have to lower the cyclic throws in the Tx a bit maybe. You could also simply try bigger servo arms - remember when this heli came out, we didn't have super-strong, super-fast servos so the mechanical loading was designed in such a way that 'ordinary' analogue servos could cope. Pop in some medium-range modern digital servos with a 6V power supply and you can load them up with more mechanical advantage through to the head without any bother.

There maybe other easy to achieve solutions that would increase the range without compromising stability - need to see a decent picture.

What ever you do, keep and eye out for binding, and try to find a solution that gives you the range without fouling itself. Go experiment - it's called modelling.

[KevDavies]

Gotta admit, Id love to get some of the older models I had like the nexus, concept 46vr (flappy head one), Shuttle, and pimp them out with decent servos and engines etc. Im sure we could make em fly lovely, not like I remember them as completely the opposite to that LOL.

HMMMM Ill have a look at ebay and see what can be had for buttons, can see a project coming on

[Steve]

Just get a Raptor 30 with an OS32 motor, some £40 digital servos and go fly - already got a 20 deg pitch range and will fly inverted and backwards all day long, and it will teach you to be gentle and careful with the collective control because you'll never have the 'power on demand' to get out of jail like you do with a 50 heli.

[KevDavies]

But a rappy is cheating, cos we already know they can fly well. What I mean is get something we take as doesnt fly well and make it so. I already have a 50 titan airframe on the way for one project LOL

[Steve]

True.

I know of a well know 3D flyer (Edders) on this forum who used a Shuttle to learn to fly inverted many years ago. Now the Shuttle also only has a 15 deg max pitch range, so he just modified the head geometry so that it had about +6 deg and -9 deg. Just enough positive to take off, lift and hover, but then he just flew it upside down to learn. Cheap and cheerful woodie blades by the bucket load and 1500 rpm head speed = 25 minute flights on a tank.

Happy daze.

Take just about anything, so long as it has half decent power and won't self-destruct, and just put a flybarless head and a BeastX on it and the transformation will be huge. Then if you want to go a step beyond, convert it to a 12s electric power setup.

[electricsceadu]

go flybar less on the nexus
use a direct link from the swash to the blade grips and you will get more than +/- 10

and the shuttle can flt inverted on - 6.5 deg, just wind the head speed up to mega amounts

550mm blades is standard for a 30 size but Align use 520s on the 550 and now Mikado ship the Logo 500 with 520s both of which I consider to be 30 size models. Either way you will not have any trouble getting good quality blades.
