Eachine or JJRC H8 mini ?

I have the X9 and like it, although not quite as much as the H8 mini. X9 strong points are great vertical lift and stability. It does have good pitch for attacking wind. Maybe due to flex body design or canopy its blown about a little more than H8. Yaw is adequate, but a little slow for my taste. To me its a great little machine, but not quite the beast of awesomeness that H8 mini is.

I'm growing to like the X9 more. It's a wonderful outdoor flier. It's a touch bigger than the H8 which seems to help. Also heavier, 12 vs. 16 grams. It seems more balanced to me -- probably a sign that my model.ini for the H8 needs work. The H8 tends to slide sometimes on turns. (I wonder how the H8 would fly with X9's larger props on it.)

The X9 may flex some, not sure. But whatever it is I like the end result. Good training quad. Small inputs cause it to tilt and move and telegraph its actions. It fights gusty winds better than my bigger quads. Though my fingers get more of a workout while doing it. It's extremely quick. So many times I would have crashed a lesser quad, the X9 powers out of difficult situations. Plenty of power all the way to end of a charge. That's cool.

Edit: They both weight 12 grams. Had a battery in the X9. :-/

Just to report that the Eachine H8 flies really well with my devo 7e! Using the Model17.ini, posted in this threat.
Thanks guys!

Works pretty well here too, a big THANKS to all of you guys.
However, i have a little concern, i cant bind my frsky receivers anymore since i flashed the new deviation firmware (deviation-devo7e-v4.0.1-ee51ea2 )
i used to use a nightly build, in order to control frsky, is there a way to get them both ?

Is there a Nightly Build with the Bayang protocol for the 8S yet, or an ETA when there might be one?

Hello! Do you know how and if is possibile to calibrate the H8 mini with a devo 7e? With its controller is just put the right and left sticks in lower-right position but it doesn't work with the devo and I need to calibrate it.

Thank You!

yes it is possible, i did it. Actually u shouldnt try to calibrate the eachine, but the devo, do u know the way to do this?

The model ini for the 7e posted earlier in this thread is for the 7e with 3x2 switch mod. The two 3-pos switches control the rate. Switches in default position indicate lowest rate, and at least on my H8 mini, it does not calibrate in the lowest rate. By setting both switches in the middle, the calibration works properly. So, if you don't have the 3x2 switch mod, you would need to edit the model.ini file to adjust default rate on both sticks or assign another switch to change rates.

Looks like hexfet's changes are in the latest nightly. deviation-devo10-v4.0.1-2cde795.zip , I haven't tested yet, plan to later today
THANK YOU HEXFET!

Hi all, so I have the latest nightly of deviation installed and I took Phillycopter8 ini file and loaded the model onto the Devo 7e but I cant get it to bind, how do I diagnose the problem? THis is the first time I use the 7e but experienced with R/C.

do u have soldered the module Nrf24l01 ?

oh, how silly of me, no I have not. Can I extract it from a H8 TX or do I need to buy one?

I don't know about harvesting from H8 mini controller, but if you are going to mod your 7e, you should just install the NRF because:
1. clear & documented instructions with support already built into devation firmware
2. you would get a whole bunch of other & future protocols enabled in the bargain.

this is the one I installed -- works like gangbusters

You can't use the H8 TX module because it's an XN297 based module.
You need to install a real nRF24L01+ module.
Retrobit's advise is right

I installed the nightly build deviation-devo7e-v4.0.1-6b6e0f4
then the dfu from deviation-devo7e-v4.0.1-fb23eb7 (the hexfest combo) for the H8
copied the protocols
And the H8 model .ini

and the NRF24L01+

I'm not able to bind

Is there a way to debug & try to understand why it is not binding ?

Cheers

There's not much to check as this protocol just sends blindly. Does your tx work with other nRF24L01 models? No '*' in front of the protocol name?

Any news on when this protocol might be available for the 8S?

The remote is brand new and i have not tried it with anything else, I have an Hubsan that I can try it with. I'l post it once i tried

Is there any difference with the + and the non + model of the NRF module ?

Thanks for the help

This protocol is merged into the main branch, so should be available for all Devo models in last nighlies.

The Hubsan protocol is using a different transceiver (A7105).
Do you have really installed an nRF24L01 RF transceiver?

About the differences between + and non + nRF transceivers, the main difference is the lowest datarate possible.
For this protocol should not be a problem to use a non + transceiver.
SymaX protocol doesn't work with a non + transceiver because use a lower datarate non compatible with non plus RF transceivers.
