Here's my first-ever RC ROW flight. What a blast! She has plenty of power, however the added drag & weight is definitely noticeable. The floats shift the CG slightly aft on my airframe. Not enough to cause any problems, but just enough to be a bit tail-heavy for a Cub. I moved my homebrew, lightweight Hyp 240 pack forward approximately 10mm, which turned out to be about right.
Although there is something about seeing a Cub on floats that makes a person smile - there is something about flying
a Cub on floats that makes a person grin from ear-to-ear - and keep on grinning for hours afterward!
Now that I have established baseline performance on land & water, it's time for a 5030 prop.
