My question is about the thrust tube length. Doesn't the length from the fan to the exit somehow come into play here? I am asking as I have moved the fan back in the fuse as I am planning on using a 204g battery.
Thanx for the assist!
I use 1.8" on the 60mm fan. I try to keep the thrust tube no less than 5-6" long on the 60mm fan.
