issues trying to upload a AS3X/safe select profile to AR637T

[xviper]

problem - finding it really hard to turn in this mode, is seems like the settings are too high, not sure which one.[/B] 🙁

any suggestions on the how to fix flight mode 2/3 which are using safe?

"Safe" is a function in itself and is only indirectly affected by gain/priorities. If the stabilizer works as you like, best to leave gains alone. When you have it in SAFE and crank the AIL stick full roll, does it go to around 45 to 50 degrees of bank? If it does, I think that's the way it is. Banking in SAFE and using ELE does require quite a bit of space to do a complete turn around. You just have to learn to slow down a bit for the turn (without stalling) or only activate SAFE in emergencies or use it on final (as I do).

i asked the guy at the club about the stock reviver however he sold it as soon as he got the plane as he runs futaba.

so i went through the videos they confirm in the videos that the AR637T will only be programmed with the "forward programming" through the Tx.

I setup up AS3X using the values i found and then set up safe using the videos from the link above. i flew the plane yesterday and the As3x is working great.

The safe select values dont seem correct.

i setup as follows:

flight mode 1 = AS3X - rate gains (roll = 40% pitch = 60% yaw = 70%) - works great - 🙂

flight mode 2 = AS3X + safe "Envelope" (gains - roll = 35 pitch = 35) (angle limits - roll = 75 pitch down = 40 pitch up = 50) - problem - when the angle limit is reached in roll the plane "bounces" back 🙁 - should I reduce the roll gain to 25?

flight mode 3 = AS3X + safe "Self-level" (gains - roll = 35 pitch = 35) (angle limits - roll = 75 pitch down = 40 pitch up = 50) - problem - finding it really hard to turn in this mode, is seems like the settings are too high, not sure which one. 🙁

Thanks, I have those YouTube vids bookmarked for when I get my first 637T. Yes, those gains and priorities will give you the same AS3X characteristics. The only thing I'm not sure about is how to program in "safe select", which the BNF has. Perhaps you could get the club member who you got the plane from and see if he still has the stock RX and take the programming from it.

Hi Xviper, thanks for the reply

So from what i can see, it is not possible to use the PC spectrum programmer like on the 636. i found that i can view the standard V900 setup file using the pc programmer so i now have the gain values.

So i guess i just have to add these manually using the forward programming through the Tx and then it should be the same as the stock plane?

Found these videos on YT which should help: https://www.youtube.com/watch?v=hxHT...D-8T-2&index=1

I don't have a 637T to play with but other flying buddies have. As for the 636, I've had mixed success with it. It depends on what plane it came out of. Those from certain planes (in my case, an Opterra) is "locked" and you can't do anything with it. However, I've been told that even with these, you can get a download from Spektrum that will wipe it clean so you can program it to your own specs. I've not done that yet so can't say if that's even possible. 636s that I've taken out of other planes have been re-programmable via my smart phone APP (with volume turned up to max). The APP can also be temperamental.
The 637T shouldn't be a problem. Can you program it via "forward programming" through your transmitter? That seems the easiest way to do it. I haven't looked into how to load a pre-programmed file into it.

Hi all,

i was given an eflite V900 from another club member without a receiver. i tried to buy the AR636 but looks to be discontinued so I bought the suggested replacement AR637T.

i was hoping to follow the youtube tutorial from: https://www.youtube.com/watch?v=7Np6CBNF0ZI

I've registered the receiver and updated to the latest software however after that I cannot use the spectrum PC programming software to do anything else. all else apart from software updates is greyed out.

Am I doing something wrong? is the AR637T not able to have profiles uploaded like the 636?

I would like to fly the V900 with the stock setup as I've never played with AS3X and safe select would be useful for my first flights as this is my 4th plane.

Thanks!
