微型个人资料J3配备了有刷电机/齿轮箱组合和3A刷ESC预接线，所以没有必要焊接。强劲的EPP发泡将处理撞击和使J3室内飞行爆炸。你将需要2个超微型线性伺服系统，100〜138mAH电池1S和你自己的发射器和接收器（TX / RX）来完成这个模型。眼镜：
你自己的4通道RX / TX
I got two of these. The model airframe is pretty sad. The deal is a good one though if you look at the GPS6 and prop and esc for this price by itself. And HK, while this goes for 16 bucks, the motor,esc,gearbox and prop sells for 20 !! And folks who bought this same thing without air frame for 5 bucks more didnt do enough research ofcourse! Whether its or huge inventory or lack of manual intervention, this gap nees to be fixed unless you tell us that the other offer is different make/quality.Hmmm, this was not a great unit. The foam is over blown, making it very flimsy, and the motor did not walk at all. Not the best indoor setup at all. As a glider, however, it flew really well off the balcony, without the motor. Servos had to be rewired.This is an interesting little indoor flier. Used it as part of a test to begin indoor flying at my school. The foam is a coarse blow, and very flimsy. I would have been better to have a carbon strip in the wing. The linear servos are a little slow, the faster you go. Very Noisy gearbox.
Those were the only negatives. It flew really well indoors, in a small gym. Very beginner and child friendly, and can handle bouncy landings, just re-set the gearbox. Have fun.Well this plane looks great, the package was fine, there were no damage, instructions for assambling is including, you need some skill to place the parts in order to find the correct C.G. , for me is exactly the plane i was looking for, very stable flying indoor, i use the parts i mentioned in discussion, i replaced some connectors and i did connections using coated wire, very useful for light planes like this, overall weight 23 grams and it flies really nice. if you like to do previous work to get a good flying machine i really recomend it. as soon as possible i will post a video.
