If you ever happen to get involved in Radio Controlled planes, boats, cars, or helicopters, www.rcgroups.com is the best online resource for help, questions or open discussion. I fly electric RC planes and have gone to rcgroups.com to research a product before I purchase it. Why buy a bad product when you can find the right product for you… all before you spend a penny of your hard earned money. I have also used the site to share my experience building and flying my Piper Cub, P-47 Thunderbolt and Multiplex Easystar. More on that later. I just wanted to tell everyone about this great resource….. and it is free!
