This is by FAR the easiest ARF that I have ever assembled. Everything fits great. All the little things that are already done for you saves a ton of time! I think they said to themselve's, "what do most hate about building an ARF?" The cowl blocks are already glued on (with the blind nuts insatlled), the horns are already mounted on the ailerons/ele/rud. the blind nuts are already in place in the firewall, the tailwheel wire is already mounted into the rudder,etc.etc. ( I hate doing all of this!) I am using an old 46FX that by far exceeds the power of my 46AX. Good stuff
