Testing:
Cons:
The RTF Boat has excessive roll gain and needs linkage modifications.
It also requires 5 significant steps to complete the readiness for flying.
The boat flies twitchy and top heavy.
The single conversion receiver had glitches in our office park.
The main body near the inner edge of the pontoon is very weak on both sides
and will break on seemingly reasonable landings.
Pros:
The power level is excellent.
