Hints and Tips Discussion MJX X600/X400 Transmitter Modification, Remote Distance Reached 260 Meters

I hope it's the correct section for posting this.

Remote control distance of MJX X400 is too limited, it is not enjoyable, so hands-on retrofitted the remote control and the receiver's antenna, through field tests, can reach 260 meters.

The original intention is to try to do more with less, this modification will cost a few dollars, but nearly double the distance can be increased more than the original. This Modification Program has not yet seen in other places, is an experienced chinese player release on internet after screening test, good things are not exclusive, share it with you.
