EZ Power Pack Pizza Box

The "adults" in charge want to be featured on the news and take credit. Some people are still mad that, the last time we did something similar and they invited the media, it was my picture in the paper.

Suggest you do the following. Take pics/video throughout the sessions. Look for teacher conferences, STEM meetings/conferences, prepare a 50 min talk using pics, video and submit outline, goals to see if you end up a "speaker". That is the way to see if they provide the funds(get even) to let you do that. Also, suggest you submit Flitetest (J Bixler) info on what you accomplished with STEM equipment and your students.

Not a bad idea, but my primary goal is getting kids motivated to learn. I really don't care about taking personal credit.

ETA: I do somewhat take offense when kids are shortchanged by adults that are in positions where they should know better, but don't.
Unfortunately this is a fact of life and something that is unlikely to change.

 

[BadAir]

So, had some kids build one during lunch and it is predictably rough, but I'm really impressed. I'm going to have to refine this one for my own purposes when I get a chance.

 

[BadAir]

Anyone have a weight for the V.2 battery pack?

It uses Losi 2 connectors?

 

[BadAir]

So, my EZ Power Pack V.2 came in.
For the record the battery, motors, props and board between 25 and 26 grams combined. My postal scale can't do any better than that. I'll take it to the lab on Monday and get exact weights for everything.

The battery is about 10.5 grams on my scale. It might be a place to save a couple grams.

EZ Pizza Plank works!

I'll update the plans and edit them accordingly, as they were altered significantly to be adapted to cardboard. I'll also simplify a few things to make it more repeatable for kids to attempt.

That's awesome! Thanks for doing this!

@AgentC
Looking for 2 inputs.

What is the AUW and could you try holding the plane vertical and see if you can get it to do a hover by doing a quick release/grab?
Looking for ballpark figure what % throttle allows it to hover.

I'll have to do the vertical test and get back to you. It won't hover though due to the built-in gyro, but a VTO(-L) attempt could be a fun experiment...

 

[Piotrsko]

Then turn the gyro off. Jeez. kids anymore........

Lovely effort @BadAir for the kid designed foamie, might is suggest looking at the KFM3 flying wing and somewhat maintaining proportions of the steps? Mine periodically attempts to strain itself through a chainlink fence and survives. I probably should stop doing that but the stupid plane won't die or even crinkle up. does dent the leading edge in a pleasing pattern.

 

[BadAir]

Mine is 27.8 grams

So, I have 3 sets. One shipped with 7mm motors (Ironically the one in the box marked V.2).

Of the the 2 with the larger motors one is 25.5 grams the other is 26.3. The biggest inconsistency seems to be the battery which can vary half a gram.

I know it won't hover, it is not a V-TOL, but a STOL, like this.

I look for things that don't exist, concept is gather speed, it lifts off and up and better than 1/2 throttle, it climbs, back off throttle to level off and flys around and lands. Ultimate goal would be to do a barrel roll and stop at inverted and then land inverted. Yes, it can be done. Concept is plane is symmetrical, so you can take-off inverted and land inverted. Fun with it in cellar as is and run it around with differential.

My proposal for a VTOL(should work) is put 2 units under 1 tx together with a 90 degree X configuration. With 2 tx, might have some fun.

Reason is I am asking I am doing an informal collection of wt of plane, design, flight, and how does it hover(if). I have 7 different models that I designed and very interesting results. Want to add any one else's for gut feelings. My number 8 design is above.

Behold! The Hammerhead Eagle i-Thrust.

It needs a little work, but we should finish it this afternoon.

Cool! Is the bottom right the front? Canard style?

Be sure to flip the board over with the LED down.

Yes, although you could probably flip the props, etc. and fly it the other way round.

 

[BadAir]

So apparently that is supposed to be the bottom. We got it sorted. It weighed 50 grams prior to getting it balanced with a nickel on the nose. Call it 56 grams. Flies like a bat out hell, steers like a cow.

Very sensitive to throttle. I'm not the world's best flyer, but there isn't much between zoom climb and dive. Nonetheless, it was easy for my students to keep in the air the length of the gym, which is all that matters.

That makes sense. The red motor is the left side motor.
Be sure to keep a minimum of ~10% throttle so the gyro/steering will function.
How far apart are the motors? I find having them roughly 6-7" apart helps with control.

 

[Piotrsko]

Making the "canopy" much bigger would add more rudder effect, but I suspect it steers like a cow because that's how differential motors spool up and down, takes a second to get noticeable thrust changes then and another heartbeat or two to have it start to respond.... Better to have more distance between them like @AIRFORGE said.

I am impressed with the design.
