I got my Clean Install kit Friday. I went to a local area that's heavily wooded (type of area where I do most of my SAR flying) and did a practice flight with everything Factory Stock! I hit just a pinch over 3,100' at 150'AGL before lost Tx signal and aircraft initiated RTH. I did this flying directly North and flying directly West to get a good baseline.
Before MaxxUAV Antennae Mod:
North 3,100' @ 150' AGL
West 2,800' @ 150 AGL
I ran home, did the Clean Install and returned to the same area. Both directions showed significant improvement.
After MaxxUAV Antennae Mod:
North 5,900' @ 150' AGL (90% increase)
West 5,100' @ 150 AGL (85% increase)
This gives me an average of 87.5% improvement in a Real World scenario. I couldn't go any further in the above test because it was putting a mountain between myself and the aircraft and I'm pretty sure very few mods will be able to penetrate the mountain. I'm confident on flat terrain I would have seen much improved distances.
The install went very well. I was surprised when I opened the Tx up (
never even attempted to open it before) that one of the tabs for a screw was broken loose. When I backed the screw out it became free floating inside the case and when I opened the case it fell out. I've never touched any of the case screws before and I'm pretty sure it was over tightened at the factory and was concealed damage until I removed the screw. Oh well.
Installed was by the book (err I mean video) which helped a lot. I kept the laptop on the table and went step-by-step with the video. Easy as pie for the most part
Thank you Jake

Well done.
