Hobbico is the parent company of the rest.
CMP is NOT Nitro. Was not hard to find this:
http://cmpairplane.com/contact.html You will note that the contacts for the company are NOT connected with Nitro. CMP sells low end ARF but if you want to work it is decent value for the money. Their latest model an Bf-109 is actually pretty good.
No idea why Nitro is playing games. Maybe just for the free advertising. But they are playing games since Desert Aircraft has asked them to remove the ad.
This is just dumb. Nitro seems to be decent to their customers most of the time and they have plenty of ads out. So why be a jerk about using the term DA.
