Re: Wright Stuff C

Could somebody break this down for me into more general terms? I’m very new to WS lol (It’s from the Josh Finn kit): “Please note: we now recommend adding all ballast required for the 8g minimum weight to the nose, then balancing the model at 50-55% of root chord by sliding the wing forward. Add st...

Re: Wright Stuff C

<SNIP>The biggest issue I can see for Luke that will make or break him is little errors that end up being costly. <SNIP> This is pretty common. One of the side benefits of science olympiad is the experience of dealing with pressure and developing strategies to manage it. One suggestion have Luke de...

Re: Wright Stuff C

One caution, if your plane starts changing from climbing to diving as you increase torque, you really need to check for motor stick bending. If you have it, I think it needs to be addressed before you start making trim changes.

Re: Elastic Launched Glider B

Depends on where you fly. And it us usually an estimate, not an exact number. If you fly in some place with cement block walls, have someone stand to the side and count how many blocks high the glider flies. Estimate how high as a rough percentage it gets to room height, say 25%, 50%, 75% etc. Then ...

Re: Wright Stuff C

Why would a great long flight get you banned, that IS the purpose of the event afterall! Again, NOT official, only one person's opinion. Before you ASSUME it is not legal, I'd recommend you request a FAQ or clarification from the NSO website, www.soinc.org It might be considered OK under general rul...

Re: Elastic Launched Glider B

Start with a SIMPLE proven design. Many conventional AMA designs are close enough to this years rules to copy with minor adjustments. In trimming the planes, CG and decalage are important. To transition properly, most designs have a 0-0 wing tail angle of attack. Must adjust CG for good glide. If th...

Re: Wright Stuff C

Haven't done this much this year, but general caveat because as some of you know I'm an event supervisor, but NOTHING I say on this forum is official. ONE opinion only. A google search on "f1d variable pitch propeller" and "f1d variable diameter propeller" will show images of what folks are talking ...

Re: Climbing issues

Depends on the design of your prop hanger. The general idea is to change the axis of the prop shaft so it points down a couple of degrees.
Some prop hangers can be bent down, some you have to re glue with a down angle.
Most indoor designs recommend this.

Re: Climbing issues

Sounds like a power stall. Instead of giving up fuel by backing off turns, consider adding down thrust (1 or 2 degrees) to the propeller.

Re: Wright Stuff C

after reading some stuff based around tennis and tennis rackets and the addition of weight to certain spots of the racket, it led me to the thought of this years ws. With this years planes being relatively easy to build under weight, meaning that ballast will be required, does placement of the ball...
