Default Weight...I have a question!

Just curious how much your Hangar 9 or other 1/4 scale Super Cub or J-3 Cub ended up weighing? I'm using the 1/4 scale cub floats sold at Horizon Hobbies.

I'd have to dig out the article but I remember adding quite a bit of weight to the floats on both the Beaver and the Super Cub.

I figured out how much I needed then mixed lead shot with 30 minute epoxy and poured it in the ballast hatches and sat the floats on their tips so it ran all the way forward.

Even with the weight the Super Cub flew ok with the 26 they sent with it. A new cowl and a Valley View 40 though and it doesn't know the floats are there

Bear in mind that the J-3 Cubs at Jack Brown's seaplane base in Florida have 100 HP engines (only 80 HP the first couple of times I flew them).
Their rate of climb is sedate to say the least.
So if you want scale realism, pull the power well back and just potter around.
Also, for scale, it's rudders down for taxi, rudders up for T/O & L.

In an hour and a half in a J-3 I lost count of the number of touchdowns and takeoffs, and we never went above 500 feet.
