I cant speak about Nitro , I wont buy from them because I wont deal with a company that likes to use differant business names , Nitro , Egrand buy , Raidentch , and about 7 other names are one companys

But ... the planes are what you need to look for ... when it comes to fule planes , they were carrying CMP and Flymodel copys of CMP .
If you look at some of the ads (because there so good at chaneging and updating there website lol ) you can still see the three differant versions of the 73" P40 , One was a real CMP the other was the Flymodels , same with the Hellcat , the SPit and the giant At -6 texan . Flymodels is a chaper copy of the CMP .

I agree with others to buy your CMP planes from Alex in Texas .I ordered my BF109 from him , got a great deal , quick shipping and no problems and you can reach him on the phone , he actully picks up what a novel idea .
