This micro quad uses a Superior Hobby SRP8 FRSky Rx that browns out VERY frequently due to insufficient voltage. The SRP8 has a minimum operating voltage of 5V but this quad runs off a 1S LIPO. Additionally, I noticed that the middle voltage pin powering the Rx board had only about 3.5 volts on it, even when the LIPO was fully charged. So I unsoldered the center V+ Rx pin to break it's connection to the flight controller and then ran a wire from it directly to the LIPO red wire power. Now it works much better and brown outs are far less frequent. Even still this Rx is designed for 5V so is still sub-optimal. Also the prop protection ring is a great idea but is extremely fragile. A nylon one would be much better. Despite these drawbacks I like this little micro quad and the fact that it works with my FRSky radio and is based on Naze32/Cleanflight. Only consideration is that I can't recommend it to anyone unless they have the soldering skills to do the mod above (or the vendor fixes it). Summary: -Weighs only 27.7 grams w/o LIPO -Works well with 380mAH 1S (http://www.banggood.com/Upgraded-25C-3_7V-380MAH-Battery-For-Hubsan-X4-H107-Ladybird--p-69870.html) -Handles well -Fragile protection ring - Should be made of nylon -Serious Rx power design flaw that's 'mostly' fixable with modding -Spare props not included -Camera is decent w/wide angle lens *Would rate 5 stars if no Rx issue and included a nylon prop guard
