Yes, I have a good opinion and suggestions. In my opinion, you are violating RCU's terms of service. You are not a hobbyist and therefore have nothing to contribute to the forum. My suggestion is to get an advertising account on RCU and pay for the publicity you want. Ethical companies are always welcome here to let us RC guys know what the next cool gadget is for us to spend money on as long as you pay for the publicity instead of trying to steal it by posing as a hobbyist with your broken English.
