M.A.R.S lite parachute kit

[J.James]

YA I could see some thing like that home made ball bearing tilt switch being problematic with any kind of aggressive flying going on. Esp if it were able to work from a free fall speed considering the p3 and other phantoms can fly faster then there top free fall speed which is in the mid 40s to 50 Mph depending on weight and air density. But The p3 can hit them speeds + when going full bore and it stops pretty fast to. So It could possibly cause a deployment on a fast braking action or direction change.

But it might work great on some thing more lumbersome and slow moving. esp On them home built jobbys were they are even made of lumber with some motors and flight controller nailed on a cross made out of some 2x4s lol

 

[Keith Lampman]

Defiantly! I would be worried that it would deploy while flying aggressively [emoji15] Keith or MIT One, due you know what the Mah rating of the battery backpack is?

Not sure, but I bet it's under 300mah

 

[M.I.T. One]

I would guess around 100mah just based on size and comparison.

yea your probably right

Here is normal Polycell sizes;
120 mah = 30 mm x 20 mm x 3.2 mm
200 mah = 30 mm x 16 mm x 6.2 mm
250 mah = 30 mm x 16 mm x 5.6 mm
650 mah = 62 mm x 35 mm x 3.8 mm

If it is 100 mah than the servo and Mayday is pulling 40 ma in the set position giving you roughly 2-1/2 hours of battery life. Does that seem about right?

What is the weight of the battery backpack?
Sorry for all the questions LOL

5.6 gram battery pack and .14 grams for mayday is what I just weighted................In my tests so far I have got over 2 hours each time, so I would think you could run through at least two flight batteries safe, like kyle said 40 minutes at least, I'm going to try three......I bet that red led draws more mah than all the other parts total.....lol

 

[Jbundy63]

Yeah I bet your right on the mah led draw [emoji15] Thanks for letting me know the weight. I'm ready to start some testing as well, just need the rest of my stuff [emoji848]

 

[Keith Lampman]

Will the Hubsan Parachute Recovery System bolt-up to a Phantom 3 and will it give MARS PARACHUTES a run for their money ??

 

[Jbundy63]

If not I bet it could be modified to work.

 

[Keith Lampman]

If not I bet it could be modified to work.

(I think we will find out soon)

 

[Jbundy63]

Are you going to try it?

 

[Keith Lampman]

Are you going to try it?

There are some over on another thread that placed orders, I hope they can get them to work, hey, for $119/shipped complete with battery, as long as the quad tills more than 80* and doesn't drop straight out of the sky like a rock and you are at least 50ft up it should work just fine !!

Really! Do you have a link? Do you know chute dimensions?

That's interesting, I believe the chute is 27" They don't say, but looking at the other chutes the end number is the size. Would sure like to know if someone tries this.

Thanks Keith, I'm messing with mine, hooked up a 9 volt battery 500 mah and my setup with two servo's are pulling 60 to 130 mA it fluctuates due to the servo holding position, running time to see how long this holds @ 1 hour 10 minutes and looks like it has dropped about 1.5 volts so far. Something to mess with in bad weather [emoji16]

Most any battery should work OK, just watch weight as more will reduce flight time, sometimes "smaller" is better

 

[Jbundy63]

Definitely on the weight! I was just wanted to see how long a 9 volt 500 Mah battery would last until deployment with the two servo's. Around 2 hours 15 minutes. Looking for a temp battery/charger until Kyle gets things figured out, I really wish if the battery gets low the servo's would stay in the locked position instead of opening.

 

[Keith Lampman]

I'm looking at that "low-battery" thing as a fail-safe, it forces you to make sure battery is charged, (at least you don't have to worry about tilt over 80*, lol) here is another diy site that is cool if your super handy and have a 3d Replicator machine laying around your home !!
