Before any radio transmitter purchase, it is always interesting to have look to the user manual as it gives you a good feeling about the capabilities of the transmitter. Since the XG8 from JR, which is a clear signal of the divorce with Graupner, but also Spektrum, I was looking for the user manual, by curiosity. In the past JR transmitter were not "glider oriented" compared to the MX22, or graupner equivalent.
It seems that the XG8 is better and propose out of the box the necessary features we need.
I let you have a look to the user manual (in English) and make your opinion.
