RE: Thunder Tiger Rare Bear ARF .61-.91,63
Rare Bear obviously works as full scale. Probably works OK as a very large model, but as you begin to scale that shape down, you can not scale down the air molecules it has to go up against.
This is why I put my money on skinny models with skinny wings, dollar per dollar.
I see a lot of guys seeking speed in this size range getting mediocre results for a ton of money spent.
