Re: Trimming

Anyone have advice for flying at Nationals in this huge room? If you have not seen the room: http://www.scienceolympiad2015.com/Documents/PDF/RoomPhotos.pdf We fly in a 24ft gym. We do not even completely know how to approach a ~60ft ceiling. Should we increase the torque with a thicker motor to ge...

Re: Trimming

Is there any way you could wind off your plane and then attach the wound motor to both the propeller and the rear hook? This could be done on a torque meter or something else. You can make a winding stooge that mounts the torque meter at one end, and has a dock for the winder at the other. Clamp th...

Re: Trimming

I have been having issues with my rubber bands breaking very frequently. they will break after only 5 to 10 flights (about 1300 average winds per flight) and the rubber band is a .094 thickness. Earlier this year, we wanted to establish the breaking point for a new batch of rubber we had received. ...

Re: Designs

Are we allowed to have a a piece of wood that disconnects a circuit to stop the motor for our lifter(to prevent damage) and moves the golf ball toward the jug? The piece of wood is initially completing a circuit while inside our lifter. Once the golf ball reaches the top, both the wood and golf bal...

Re: Designs

Thanks to all the ones involved in these decisions; it is obviously a very difficult task. I also want to ask how many ETS steps some of you have been able to get into your device? We began very early lifting golf balls for the ETS points and when that requirement changed, it did help us on one of ...

Re: Design

. . .I start with the Bernie Hunt design spreadsheet . . . Almost all of the airplanes my students built needed about 1 degree less wing incidence for a total decalage angle of about 1.9 degrees. . . Sorry for the very long message. Brian T. Thanks Brian, for your thorough and detailed answer. I ap...

Re: Design

. . .Unfortunately, when we tried flying with more winds today, the plane just plunged at a faster rate... TC-SciOly and Jander: here is something that may help to sort this out. Yesterday, I helped a student with his FF plane. This was my first hands-on experience with this design. Detailed below ...

Re: Design

. ..I can imagine some supervisors trusting only their balance; in that case what could we do to show that our rubber is under 2 grams if the balance reads more than 2 grams? If this happens, I advise my students to offer the calibration mass to the supervisor. If it reads more than the motor, I'd ...

Re: Design

If I had to chose, I'd make the stab adjustable. . . . Regards, Jeff Anderson Livonia, MI Thanks, Jeff, for your insights. Pretty much the same thing as my students are doing. On another note, you may remember a previous post, where we were having a problem with the plane not turning properly at th...

Re: Design

How close should our team go to the 2 gram limit for them motor? I've heard some recommendations of making a 1.95 gram motor. How likely is it for a balance to measure it as more than 2 grams at the competition due to error? As Jeff Anderson has stated previously, the more rubber you have, the more...
