Replica de 10" AR-15 AEG C.A.T. Explorer [ARCTURUS]

Hello, let me tell you why you should avoid buying any of C.A.T series by Arcturus. A few days ago, I purchased the following model C.A.T. Explorer 10". The main reason I choose this model was the MAP (Mechanical Adjustable Pre-Cocking) Sector Gear. If only I knew how much trouble you could get because of this feature I would never have purchased this product! Out of the box the replica overrun (double shots) with 7.4v Li-Po battery on Semi-Auto because the MAP Sector Gear. Out of the box the replica stop working with 11.1v Li-Po battery on Semi-Auto again because of the MAP Sector Gear. When I looked at the manual about these problems I was shocked! There are over 20 different problem scenarios related to MAP Sector Gear! This product is advertised as 11.1 Li-Po ready and there is a HUGE print on the box 11.1 Li-Po ready but in reality the replica stop working with 11.1 battery! In the manual they suggest for almost all the problems to adjust the level of the pre-cocking. The standard value is 8.0 that should work fine with 7.4 and 11.1 Li-Po battery but you will experience problems with both 7.4 and 11.1 out of the box. The MAP Sector Gear has 12 position markings and they suggest for overrun (double shots) on Semi-Auto to adjust the position so that pre-cocking level to be weaker because it's to strong. To make pre-cocking weaker you have to adjust the level with bigger value like 9, 10, 11 or the max 12. Basically the replica out of the box is set around 40% pre-cocking and you have only 4 available options to make it work properly. Taiwangun claims that they test all products before they are shipped to the customer. I made an inquiry exactly how they tested the replica and with what batteries because I have a problem with 7.4v and 11.1v that I bought from them! This is the second replica purchased by me from them that has a problem out of the box! I asked them for testing the same model with the same battery they sold me to check if they will get the same results so that I avoid return this replica and just open it and adjust the Pre-Cocking level to make the gun operate normally. I will update you all about this issue so that you know if this is good product or a crap one! Let's see if Taiwangun will make the tests and how they will assisst me for second time about problem with product they sell and clamed that they tested it before send it to me.
