I’m in this hobby for about a year and i have two radios 72 MHz and 2.4GHz, its not the smartest setup…
I’m building my third plane now and it will be with the 2.4 GHz.
On 2.4 the antenna is shorter and doesn’t need to be out of the plane.

Saw myself buying these flight packs which are not that cheap and thought better sooner then later to get this 2.4 GHz.

Sure its cheaper to have the 72 MHz but sometimes conflict with others at the field.

It depends on the field and how much you want to get into this hobby.

I have the tower hobbies 6 channel, its cheap, working well, warranty, dual rates and end point adjustment and that’s what I need.
