did you find other/better battery`s for use?

Cannot connect to JJRC H31


Hi, I have just Purchased the JJRC H31.
I have left it charging for about an hour however I cannot get the remote to connect to the drone.
I have turn the drone on & then turn the remote on. Throttled up & down but will not connect. Red light is just flashing and Beeping really fast on the remote. Instructions do not make sense. Any Idea what Im doing wrong?
Thank you

I was wondering the same thing. I just ordered this quad as well as the 3-in-one module for my Devo 10 that I was hoping to fly the H31 with. I hope somebody has tried it with deviation and reports back before I tear open my Devo and fry it trying to solder in the module.

I was just thinking about something similar. Has anyone tried it yet?

I own a Devo7e with nrf24l01 module.
I want to buy the H31 and fly it with my Devo7e,
then give the H31 transmitter to my brother who has an H8 Mini.

That is, I'm assuming the H31 has an nrf24l01 compatible receiver like all other JJRC models.

Also, can somebody post a pic of the internals of the H31 transmitter? I'd like to convert it to right-hand-throttle.
(I found the pics in another review : https://www.rcgroups.com/forums/show....php?t=2698028 )

Seems like you must have a defective unit, I'm able to connect with no problems using the steps you said you did.

I'm getting around 5 minutes of flight out of these batteries, slightly less than the stock batteries.

That's my question really :P
I want to buy this, but don't have anything and I suppose this item only come with a standard 'one-battery-charger'
Since you can only fly about 4-5 min, I would like to have 4+ batteries ready for usage. And to charge all those batteries...I need a "Multicharger"
