F A S T Arrow

[Spacefarer]

I'm still waiting for the motor and servos for my DIY design.

My spear is currently under renovations and looks a little bit unflyable.

Hey, what a coincidence, I totally wasn't looking for a way to use this motor for the past year. Let's give the Arrow a TWR of [insert super high number here]!!!!!!!!!!

And then promptly crash it of course. This might get a little hectic...

The arrow doesn't need much to be fast. I run a little 1806-2700 kv in mine with a 5045 prop and it screams, even on 3S. I can't even imagine the chaos if I were to step it up to 4S.

And that's exactly what I have planned

Lol, post a video.

So I had another little idea:

that 4s battery will be pretty heavy after all, why not counterbalance it? Yay or nay for deadly torque?

it has been done...just saying i highly encourage that kind of behavior.

i'm kinda doing the same...LINKY

good luck,

Try it, but I feel like the arrow may be a bit small for that. Might have better luck with a versa, it's a touch bigger.

Thought this was relevant. Here's my arrow on 3S, flying at about half throttle most of the time.

DO it!!

is it bad if this could theoretically break the sound barrier in under 10 seconds?

also that power pod is there because the battery was too big to fit in the hatch... and it's the smallest one i could use.
I'm going to build a larger box to put the battery there. Despite the weight of the extra stuff, the plane still accounts for only around 50% of the weight. the rest is pure EDF. I have yet to see if the ESC will go up in flames. But hey, anything for science.

 

[IcedStorm777]

With all due respect i don't know if that could break the sound barrier an any universe while staying intact.

I flew it and it did what it was supposed to do! kind of... video will be posted tomorrow because it's now summer and I'm already lazy.

I'm really really bad at remembering to do things, aren't I? Here's the video:

I almost ruined the battery so I'm not going to do any flying with this thing regularly. It was just a test, really.
