Blade MSR x Getting it ready

[colintainsh]

Just waiting for the training gear before i give it a go, thanks to the chap who pointed out the negative pitch thing, you have to excuse me im an Old Fart.

Anyone have any thoughts on this, thanks for reading this.

I think that's somewhat crazy. The mSRX is a fixed-pitch helicopter, so has only got positive pitch. Changing the link lengths may increase or decrease the amount of positive pitch but if it was me, I wouldn't touch it. There's no such thing as negative pitch on an mSRX. The fact that this person has posted a video with that in the title just re-affirms my impression that they haven't a clue what they're talking about ...

Loads of people have had mSRX's. I've never owned one, but I've flown one and it was perfect out of the box.

It's only when you get to collective pitch helicopters that you needs to start worrying about +ve/-ve pitch settings.

If I were you, ignore this post about negative pitch, go fly your heli and have fun!

My mistake, reading too much about the Helis and not flying them.

My mistake, reading too much about the Helis and not flying them.

Asking questions when you're new to this hobby is never a mistake! The great thing about the internet is it allows access to a wealth of very good knowledge at short notice. The terrible thing about the internet is that it also provides access to alot of confusing and/or downright wrong info too!

To hopefully make this a little clearer. The mSRX is a fixed-pitch (FP) helicopter. The rotor blades can vary their cyclic pitch (to move the heli around), but to make it climb, the rotors spin faster. To descend, the rotors slow down. This makes for simple mechanics, and cheaper entry-level helicopters, but it comes at the cost of agility. Rotor blades (even small ones like this), don't change their RPM instantly - hence climb/descend controls on FP tend to be sloppy as you wait for the rotors to either slow down, or speed up.

The next step is collective pitch (CP). With collective pitch helis, the blades themselves are pitch-neutral (ie. they're not curved to give lift). The rotors (mostly) remain at a constant speed and climb/descend is controlled by varying the pitch (angle of attack) of the blades. With this, changes in altitude can be made very quickly, and very precisely.

Can I recommend this video series - it does a brilliant job of explaining helicopter concepts in my opinion!

Many thanks for the reply been looking at the videos, i will give the Blade a go soon, i have a Funcopter as well, did manage to hover that a bit, the Blade 400 i have needs to be setup, thanks again for the info.

Hi Colintainsh, welcome to Heli's

+1 on Tomatwalden's post, good advice
