[Stock] Gyroplane altitude challenge

[Zipmafia]

I have been playing around with counter rotating propellers and quad rotors, havent been able to make any of them work though. Although I didn't realize that you could get the IR motors to spin that fast. Looks like I'm coming back into this challenge.

Wow... I didn't thought what small control surfaces can make that difference and prevent stall at such AoA. I need to review my design for stock leaderboard!

I don't think the control surfaces will work that well without IR freely rotating washers, and if you do go with IR, make sure you give your probe a washer to stay straight, and turn off rotation controls for your control surfaces.

:confused:DragonEG's last design was able to produce over 3 Gs of force.

@DragonEG : what are the cubic struts for? Did you use them for the stability enhancers at launch? If so, next time use a washer attached to a stack decoupler. or attach to stability enhancers to the part of the craft that doesn't spin (where the control surfaces are attached).

No I'm going to use them without mods, stock challenge crafts should go without IR.

Those surfaces can act as a very effective (and laggy, since you need a lot of them) wings. If you don't disable controls for them - they effectively act as infiniglider (rotating infiniglider of sort, yeah) which is out of challenge scope.

Well, 3g is not the limit... Propeller explosion is. I think, it is possible to squeeze even more g-force at launch, since Rotatrons don't use torque, working with direct part rotation instead. So if you could provide really sturdy blades - you can jump to the skies like Batman out of fiery explosion.

Cubic struts are a kind of landing gear, and stability enhancers too. Of course, if it was only for launch - I could use stock launch stabilizers instead.

Free washer is used already - everything beyond lower propeller isn't spinning.

And about quadcopters: covered already

They won't fly very high. And have multiple stability problems. A pair of big counterrotating propellers driven by one Rotatron is far more reliable solution.

quadcopters is fine too

[Zipmafia]

You can get more Gs if you attack stability enhancers, then get your rotors spinning, then let go with the stability enhancers.

BTW, I cant get the rotratatrons to spin the wings at any sense of speed. I attach wings to the outside and it doesn't seem to work, what am I doing wrong?

[DragonEG]

Attach something on top of rotatron, then attach wings to it.

Make sure you put all rotatrons in one IR group.

Assign "Move+" (or Move-) action for all of them into one action group.

Launch, open IR controls for groups (window with buttons < 0 > and numeric field). Numeric field acts as speed multiplier, put something reasonable there. Click somewhere else to clean focus out of field, then press button for action group you assigned earlier.

Enjoy your propeller explodes into pieces

I tried making a corkscrew with just delta winglets but it spun so fast it destroyed everything. Rotational speed does help but its a balance between weight and lift at higher altitudes.

I have a stock bearing that i could probably get to space. Pictures soon!
