am now running five different boats off the same T5 Transmiter... never had a single problem with any of it over the last 12 months
it is very basic but its very cheap too

by basic... it is a "4 + 1" set to use the old terminology i.e 4 fully proportional channels and the fith channel is a "retract switch" for aircraft so only operates the servo fully up or fully down
there is no on board computer for mixing of channels and no model memory function, there is servo reverse switches but i changed a couple of rudder servos round in the different models so all the rudders worked the same direction so i didnt have to remember to reverse any switches on the tx
good value and no problems
