This is why rcu is not about the hobby but it more about misinformation . Opjose is 100% correct and please stop with the "nitro your beloved airplane company" see unlike your perception of me I am a business man , no emotion . I will spend my hard earned money on products that provide me with value in my definition of value .
This thread is silly , there is so much misinformation starting with the drama on CMP and Nitro and copied cat brands ect .
IN essence if you buy from Nitro you are sinner for practicing your American earned right of freedom of choice , personally sir I dont care of you dont support them or anyone that buys from them .
I buy from them because in my brief experience they have served me well in price and value as well as Hobby King . Hobby Partz (owned by Nitro ) is even better then Hobby King , the servace and tracking is on par with tower at 1/3 the price .
This is a hobby and we all have choices , we dont need to bash anyone on personal drama that is not fact based , and this entire thread is laced with drama and total misinformation is all based on emotion and not facts .
Again if you want to add value to the RC community you dont start a thread with Avoid nitro , you start a thread and truly attempt to educate the rc community on the potential of a brand knockoff , then what happens is you gain friends who say "thanks for the heads up " and "what is the differance btween the two " can you explane please , that is what rc post are supposed to be , not winey drama bull .

I started a post on retracts in another thread , its over 20 pages on comparing eletric retracts on the brands vs the non brands , I did not start the post by say "Advoid Horison"
I wanted to do a real comparison and so did everyone in the hobby .
There is a reason that every brand has a knockoff and if the knockoff is done in a legal manner then more power to the freedom of choice , so why you keep allowing your emotions into your post , your not doing DA any justice when you should have stated clear but FEATURES -THAT = REAL BENIFITS OF A REAL DZ ENGINE .
Perhaps you dont know what a feature or benifit is , but they are associated with any product and marketing programs that wants to show true differenciation
