Planes don't have efficiency...

And I think it goes without saying that you're going to test the plane, many times...

what sort of advice would you like? Indoor flight is a very very large topic. What areas do you need help with?


Basically any area would help a lot for me and my team!!

Build another plane just like the one that dude sat on (without the damage of course), and you should be just fine. ;)


Those planes are kinda hard to make though and cost about $20, but they do fly for about 3 and a half mins

One plane costs 20 bucks? Did you buy single pieces of balsa wood or sheets? If you buy sheets you can make like 5 planes for 20 bucks.

Kyle:

It looked like it was a Freedom Flights kit, if I remember correctly.

49ers, you could google FAI modelsupply and get their phone #. Call and see what they have in terms of kits or information. If you are not comfortable building a kit, I think you would find it kind of tough to build from scratch with just plans. If you just want to build a plane to get experience, there are less costly ones available. If you want to have a good shot to win at States, you need to practice building the best planes you can, IMHO. Pitsco has some options, but most are tissue covered, and are about $20 also, so you may as well get something really good for the same money.

If you want, I can teach you to build from scratch. Much more creative and fun in my opinion. Plus a little bit cheaper. However, it takes a couple planes until you get the hang of it. Let me know if you're interested.

I actually started from scratch and did quite well the first time around. I used these plans the first time around - obviously they are quite a bit dated and definitely can be improved upon - but they will allow you to make a plane that flies easily a minute to a minute and a half.

http://webs.wichita.edu/scienceolympiad/ws/ws.html

I learned from there and started adapting to my own designs, eventually going to mylar covering (although I switched back to tissue) and eliminating the wing saddle (although it was great for a first time flier). But it gives you the technique and advice to start.

You'd probably fare a little better time-wise by starting with a kit, but in my opinion that takes the fun away from it, and you learn a lot less. Building from scratch will result in lower times initially, but if you're patient enough, you can do just as well. Eventually, you'll be able to trim your planes better than a kit one, and you'll probably be able to fly longer.

Sure, you can go out and buy a Dave Zeigler kit. From what I've seen, they do fly very well. But don't expect to get 3 and a half minutes the day you build it. It takes a lot of practice to trim the plane. You can get the same results from scratch, but it's more difficult to begin with, even working with a set of plans.

WS is not an expensive event. I think the most expensive thing was the rubber - and if you buy enough it'll last you many, many airplanes.

Thanks for the advice on how to build airplanes, it will probably come in handy some day.

Depending on which kit you used, it was probably the Ikara. I think Zeigler's kit comes with the narrow-bloaded Ikara and Harlan's kit used to come with the wide-blade Ikara, although he didn't make a kit this year.

You can also order Ikara (and other) props directly for three to five dollars from Peck Polymers or FAI Model Supply. Possibly other sources too.

Note, the Ikara props are light enough to need little modification for SO use, mainly trimming to diameter, possibly repitching for optimum match to your rubber. All other props that I'm aware of are cheaper, but will need more significant modification as they weigh 5-6 gms of your 7 gram budget.

Are there any other suggestions for building or modeling a good plane?

Plenty, and they've been discussed earlier in the thread.
