Alke,

All air handler systems can be shut off, or set to unoccupied. I’m guessing that you just need to find the right person to talk to. The maintenance supervisor at one of our schools told us the “can’t shut off” story so we found the person that actually knew the equipment and laughed and climbed onto the roof to shut off for us. Now we know that we just talk to him.

At another school I coach, it’s the Principal’s Secretary that can get it done. As their building air equipment is computerized, and the maintenance supervisor is so busy, it takes someone with the power of the Secretary to get him to set the computer. He sets it for unoccupied, this is different than off. Here in Michigan, they can’t turn off the heat systems in the Winter as the water pipes might freeze, so they have an unoccupied setting that is basically off unless the temperature drops below a particular threshhold.

Keep asking till you get them off. It’s impossible to get useful data with them on. Maybe get the science teachers to help ask the maintenance or administrative people for the answer.

Good luck,

Brian T

Thank you, everyone, for your detailed responses! I'll continue emailing the faculty. In the meantime, my partner and I are going to try the lobby. Hopefully, there will be calm air!!

Thanks,

Ethan

So I just received some broad blade flaring props. I have seen some talk about sanding them down. Would the purpose of sanding be to decrease their weight? Also, how should they be sanded to achieve the purpose of sanding?

Thanks

so yes they can decrease weight but ultimately its about trying to find the right shape for your plane. some planes need bigger props and some need smaller ones. you have to do like a lot of experimenting and when i say a lot i mean A LOT. you would actually trim them first, go straight across the prop in very small increments. i would only sand very lightly if the edges are a bit rough. i wouldnt experiment with rounding the edges because things can get uneven real quick. keep trimming by little bits at a time. soon, youll have the right fitting prop for your plane(s)

Ok so by trimming do you refer to cutting straight lines across the part of the prop that protrudes out?

It should be lines parallel with the central spar correct?

no no no its perp. to the central spar

Polar,

There is a much more important reason for sanding than saving weight. Also, a technique to the sanding I am referring to. Maybe another person has already posted in this year’s wiki. The FF kit instructions gives some information on this.
