Hello Guys:
I'm the designer of this train, you can see it from my profile photo. I just see this posting and thank you for all of your complains and suggestions. About this train, I have some words to share with you. I cooperated with Modul King to product my MOCs, this is one of first batch production. The other two is QJ steam engine and CRH2A high speed train.
Firstly, I'm guarantee that the part quality is nearly same with Lego. I ever visited Gobrick's factory. The machines, the scale and management of factory is same with Lego Jia Xing Factory in China. So please don't compare us with LePin. Most Chinese players also don't like LePin, his parts is worst and he only knows to stole other's design. In fact, Chinese Government already clamped down LePin now.
Secondly, your complains about the power system is true exist, this flaw is only happened in Tibet train. That is because lacking of experience of transform the MOC to the production. when I test the sample, it run well. But after sale, some people run well and some don't run well. I think my design of transmission system with XL motor maybe not stable enough. We will make more test before sale in future's products. And also welcome all of your to give me some ideals to improve it.
Finally, I hope your understanding and supporting. My wish is let more people can play the brick train with lower price, as you mention below, Lego is make little attention to train. Now, Module King give me this opportunity. His R&D ability is strong, more components for fun are designed now, include sound effect, smoking effect, curve track with different radian etc. I firmly believe our production will more and more better.
Best Regards
