I also get a lot of sneezing and sour eyes from balsa dust but I always thought this was normal.
I started a winter project for indoor flying. It's call S-POU. A ToonScale kit from Stevens Aeromodels.

Everything is very small and so fragile. At first I kept breaking parts. It is easier now that the frame is taking form and strenght.
I am using the gearmotor and cardservo from the EFlite Micro Extra300 I flew and destroyed last winter.
Honestly, I don't think this thing will fly. Will see
