Probably has to clarify things with Ryder before beeing allowed to write here again
This should not be a problem as it is the first post about the system and this post can go on until we stop asking questions.
Per the "policy" advertiser are allowed to post two "Topic" posts for marketing per month. Correct me if I'm wrong, but this looks like the first "Topic" post in which the system was brought to light in a topic.
So let's pick their brains with questions!

hong kong do not have WAAS so in USA the performance I think will be better.
So if I understand correctly the "standard" GPS antenna is WAAS enabled.

I am perhaps confused by you not having WAAS in Hong Kong.
Is not WAAS an ability of the satellite signal being used worldwide?
It can be selectively downgraded during time of conflict to limit it's usefulness so that war departments can't order pizza's for all night planning.

I agree!

But i dont understand why it should be any limit for the amount of posts for the advertisers either...

I mean, theres a big difference between a real advertisement with text and graphics in the mainpage all the time, than just talking about it...

WAAS is a ground based system that provides receiver timing corrections. It's not available worldwide. Most of the USA and a good part of Europe I believe have WAAS corrections.

yes, we have both gps position and altitude hold for the XP3.1 standard.
Thanks Westwind.

You mention that the XP3.1 maintains the heli's position until the cyclic sticks are moved and that the heli then returns to hover as the cyclic sticks are released. How does losing the GPS signal and/or barametric pressure signal whilst in flight affect the way the heli is controlled?

Cheers

hi Griffo,

First I want to say that the chance of lost track to GPS will be very very rare, if you are flying the helicopter in a reasonably open space, where most AP work will take place.
If helicopter fly to some place, such as deep in the urban canyon(you should avoid this), where less than 5 gps stars are in view, the autopilot will go into attitude holding mode that, it will start to drift slowly... but the altitude will still be holding.
There is a high brightness LED on the helicopter indicating the GPS condition. so you can see it from more than 100 meters away.

Thanks Westwind.

I understand that GPS dropout would be rare, however it's good to know how the heli will react in such a situation. I've found that rare occurances can happen quite regularly in AP situations . That Murphy and his stupid law can be a real pain in the a$$ sometimes.

Once attitude hold engages I take it the heli will no longer maintain airspeed based on the transmitter cyclic stick position. Does this mean the controls then revert to that of a normal RC heli where the pilot has full manual control over the swash pitch and roll movements?

Cheers
Griffo

I agree with Griffo, it could be as simple as a malfunctioning gps or gps antenna or other factors that you havent counted for...

How about an auto "return to base" function as a fail safe?

That would be great but would most likley require accurate GPS data, which would be difficult in the event signal loss to the GPS. I'd just be happy to have full manual control returned in the event of a component failure or loss of GPS signal.

Griffo, bad formulation of me...

Ment as an general failsafe feature.
Like its been said, there are small chances of losing the gps signal in civilized areas...

But then it need to follow the same path back again, in case of threes and other obstacles...

There is am auto mode ON/OFF switch that you can turn the heli into a normal RC helicopter at any time = )

What's the upgrade path in the event that we purchase the standard version and later choose to upgrade to the pro version? Is it a simple firmware upgrade that can be completed by the user?

Please advise if the heli requires it's own tail gyro in normal mode, or does the xp3.1 provide tail stability in both modes? and is it heading hold? I presume so.

Very impressive video. Just out of interest, I notice you kept the flybar. Is it for redundency for manual control or is it more suited to your PID loops for you system? Just interested.
Cheers.

Westwind2, is this a system that we can integrate ourselves or will you guys have to do the integration? It'd get pretty expensive flying you from HK to the US. Although we'd probably keep you here...

Westwind2,

You say you are already selling the standard version : can you give us any links to existing customers ?.

Also, can you add a picture of the other side of the helicopter ? - it seems most of the system is hidden in those pics.

Thanks,
Barry.

Yes, any customer available in Europe? I would like to visite and see him...
400g is to heavy for 600 size heli. There is still the weight for the cam etc. to lift.
What's the electrical consumption of the system?
How does it handle the engine vibrations of gas engines? Any long term experience? I just know that's an issue on different other systems.
Why do you have only six month warranty on the basic system and more on the other versions? Six month is not really long...
