Currently I own a 7 channel channel black pearl sma and my immersion 600mw just went out (I think). I was looking to get a new one and was wondering if I should upgrade to a better TX or just get the same one. I only had the immersion for a week and half so I am kind of timid of it. I am willing to upgrade to anything that will be the best in terms of performance. Advice is much appreciated and Happy New Year.
