That's interesting. My experience has been a little different. Most recent plane is Seagull Edge 60 size ARF, no nose weight added; H9 Pulse XT ARF, small amount of tail weight required; kit built Sig 1/5 Cub, no nose weight required; Dynaflite Super Decathlon kit, tail weight needed; Dynaflite Chipmunk kit, tail weight added; WM Mach I trainer with an OS 40LA, no nose weight added; H9 Twist 40, no nose weight added; Sig Rascal 40, no nose weight added; GP Venus 40, no nose weight.

In all probability, I have at some time(s) built a plane that required nose weight, but I can't think of one in my recent history. That's why I was intrigued by your statement about "all the others".

Thanks for your comments.

Edit: adding examples I forgot to include initially (!)
