Re: Design

So here is a fresh topic. I've noticed that there are different ways to trim the plane. For example, some planes have the stabilizer fixed on the tailboom, and adjust the wing incidence to trim. Others, including the ones we are flying, have an adjustable stab. We set the wing with a small amount of...

Re: Design

so im using the freedom flight models and the highest time i've gotten so far is 2:10 my plane is climbing, but not very high at all. also, it has a jerky descent. advice or ideas? I wonder if your motorstick is bowing. This would decrease the decalage, which would reduce the lift, which would redu...

Re: Design

Here is a new design topic for discussion - the bonus wing for state competition, which has a 7 cm chord. Our team has usually qualified for states, so we decided to start with the 7 cm wing. Our best time under a 19' ceiling is 3:09. But recently, we built a wing with 8 cm chord. Same fuselage, pro...

Re: What are your guys times right now?

Well, my plane seems to be climbing all right, but it doesn't climb very high. I've snapped several rubber bands like a .081 30 cm loop broke many times after about 80 or so winds on a 15:1 winder. So getting more turns is becoming difficult. Also, the knots that show up once wound hit my motor sti...

Re: Circular

First, whenever you notice sudden changes in a plane that has otherwise been flying OK, check for something broken. . . . Reading carefully I'd really check the prop axis. Consider more tail boom angle and stab tilt, one at a time. Jeff Anderson Livonia, MI Well, some bad weather forced an early di...

Re: Circular

One possibility would be that the motor you are using cannot operate the higher pitch propeller well enough to create the airspeed necessary for the tailboom offset or the stabilizer tilt to create adequate turn. First, whenever you notices sudden changes in a plane that has otherwise been flying O...

Re: Circular

. . .Now the rest of the trim is just to keep the turn a constant size over the full speed range these planes fly at. The prop is actually set with its access down and left to offset the excess lift at high torque (max winds) and off set the excess left wing lift (which increases left turn radius, ...

Re: Elastic Launched Glider B

torqueburner, . . .Were the students careful to orient the fuselage per Stan's marking for the top? . . . If you could describe the students exact launch procedure (angle of inclination, angle of bank, and amount of stretch) and the character of the flight during launch and transition, I may be abl...

Re: Winding

torqueburner, . . .if you are using TanSS it is good to remember that this rubber behaves different than TanII. Some recent comments I have seen about TanSS from high-level competitors is that the mid-range suffers a little (maybe lessening the cruise and letdown) if it is wound very hard before ba...
