Would it be okay to fly this engine at a school's field?

Absolutely as long as the kids all follow standard safety precautions being near the launch pad and you make sure you know what space you have available and where anything might get caught or lost. I use them in my yard and at the local park with my kids ages 7 and 11

Yes - if you have blasted off rockets before. You will want to compensate for wind but also be aware of any trees and power lines in the area. I have blasted off hundreds but still get surprised by upper wind differences from what the trees are doing, even with these reletively low flight engines. If you have a larger open area than a typical school field you may reduce your chance of loss.

Yes, of course! As long as you have the oxygen bar on, the field is wide open as to what you can do while using it! :)

I think so. The electric motor won't lose power like a gasoline motor would at elevation. The prop will get a little less bite, and the wings will have to move a little faster to get lift, but I think it will still fly fine. I have flown mine at sea level up to about 1500 meters and couldn't see much difference. The Ember is much loved for its slow flight characteristics, but has enough power to fly faster as well, so I don't think you will have any problems. Be sure to purchase extra batteries since your flight times might be a little shorter than the fifteen minutes that most people get at lower elevations. Fifteen minutes is way longer than most electric planes get from a battery anyway, so ten minutes will seem plenty long.

It is possible, these are blackpowder motors and thus contain both fuel and oxidizer, and ignition is electrical. I think the real issue is will an electric match ignite at that altitude. But, depending on where you live, this use could possibly require government approval/licensing (http://www.flyrockets.com/regulations.asp) The regulations are determined by fuel payload but correspond to attainable altitudes. An A size engine only gives you 1-2.5 N s of thrust at any rate so I don't think you would get much out of these for your apparent objective of getting something into space.

Prabably, but I would not as the RPMs are a bit low. This is an entry level unit.

I wouldn't personally use it outdoors . It's kind of noisey too, so if you do get it get a controller to adjust the fan speed

It will fly well outdoors only in very calm to dead calm conditions. It is too light to penetrate any significant wind.

I would think so, but I use a 12v/ 101 ah deep cycle and get a good 8 hours trolling at 2nd speed (depending on wind)...I like this motor far better than my old minkota. ..highly recommend. You can always pick up a bigger battery at wal-mart for around $65 :)

Machine would probably work for a small venue like a high school game..I think it would not work for a real high output venue.

I haven't built/flown it yet. But I remember reading that the recommended motor is somewhat underpowered (a D-12 I believe). I would plan on putting in at least an "E" motor of some type. And you will want to beaf up the internal structure. I've seen these things fall out of the sky underpowered and I've seen them torn apart before they get that far. I don't think you will have to worry much about it going too high.

It's a heavy-duty fan (bulkier than I thought) and blows a lot of air. If you're OK with that, it should be fine.

Yes it drives well on just about anything, including grass and dirt. I hope your home or room is large though, I can't imagine riding it in a room less than 20 feet long and wide enough to turn around! But it's an awesome toy.

I would not. Although it does have an enamel coating on the cage/body of the fan, I think the motor would be susceptible to rusting/shorting. This is really more of an air mover for a workshop/warehouse. It's like an airplane prop.

The supercub is a good size plane. You wont have a problem with light winds.

First of all measure it, its not even 53 inches long. The design is very critical as to the exact parts and weights. Changeing anything will not be good. Most local High schools will allow you to fly indoors in the gym. Outdoors there must be NO WIND AT ALL. Good luck... PS there are much more expensive models that are controlable for outdoor use,...

No, this is a fan motor. It Will spin far too fast. You will need a motor with significant gear reduction. It is also 120V AC.

The motor is practically silent, but the rushing air makes significant noise. On low it's not all that loud.
