Release clip testing for fishing drones (Sky Rigger, Gannet, Cannon and Du Bro)


Good day everyone my name is Pierre Hertzog and today we’re going to do a test a very important test on drone dropping
mechanisms now as you might know you get two types of dropping mechanisms you get those that are purely electrical and that’s released by a button that you press on
your drone like the Gannet X and the PGY tech I’m going to do a review
on all of these but for this specific video we’re going to test the tension
release mechanisms and there is one critical thing that’s important with a tension release mechanism that is if you set it and it’s at the same setting
then it must release at the same tension every time and I have build a test set up
and I’ll show you just now and we’re going to test the different dropping
mechanisms, the tension release dropping mechanisms like the Gannets the Sky
Rigger and some of the downriggers and so so the video is on one specific aspect and
that’s the repeatability, how repeatable are the drops depending on the weight that is applied to those drops so what I mean that is if you hook up your bait and you hook and so on, on your mechanism and a certain amount of pressure must be
applied for it to release if I hook it again the same setting is that
pressure the same is it much differant let’s do those tests so we had only one
little problem we didn’t have a scale like that and the kitchen scale would
not do, so in a hope that you will subscribe to this channel we went through a lengthy process of designing a scale, first the mechanical part and Hansie helped me with that and later on also the part the programming of the screen and the
programming of the microcontroller and after that we had something that we
could use to do this test but let’s have a look at the different mechanisms
before we do the test the first one is this one it is the
Cannon 1 in the tests we will see it’s got rubber grippers here and you’ve got a setting here where you can set the tension of those grippers so the way that
it works is you push your line in between those two rubbers like that and
it then pulls out there and you can set the tension here it worked quite nicely
of course you’ve got the problem of mounting it safely to your drone like
all the downriggers so this was the canon one the next one is canon two-
this one it’s got basically two settings one setting here it’s got a cam
mechanism and this mechanism can only turn off a half a turn or so this cam
and it sets the tension in the second setting is and you can see I push it in
one two three times so that’s the second setting for the Cannon, Canon 2 in the
results this one the next one is also downrigger
also the problem of mounting it safely to your drone it’s basically a piece of
plastic where the points of this plastic is tensioned by the screw so if you fasten that screw it will take these pieces of plastic closer together
and it will grip the line so this is the Sky Rigger it’s fastened to the drone
with these two allen keys here it’s mounted with this these closest to the
camera so that your mechanism doesn’t swing into the camera the mechanism
works like this it’s released yes opened and then you can put in your line and
then you close it again and there the line pulls out of there it’s got
a tension knob here that you can set what I found is that that a very small
change here make a big difference in the tension so but once you figure that out
there is not a problem that that’s is then the Sky Rigger next one is the Gannet
Sport now the Gannet Sports got a multi-turn mechanism so you can set that
very precisely it’s also got an indicator here that gives you indication
of the tension it’s basically two ball bearings there is a spring mechanism in
here that supplies the tension very easy to use and
to set the Gannets Sport next one is basically the same but it’s the Gannet Sport for the Mavic again a window there that gives you an indication of the
tension multi-turn setting that you’ve got and then also the ball bearing and
the spring mechanism Gannet Sport for the Mavic and our last one is the only
electrical as well as mechanical mechanism of course this part
works exactly the same as the Sport Gannet Sport where the line pushes in
there and it pulls out it can only go in one way into the mechanism and out of the mechanism so very easy to set also but this one’s also got electrical
release where you can work the light on/off switch on your drone you can
release it electrically this is then the Gannet XSport so this is the experimental setup you
will see I’ve got a bucket of water at the top that water will flow down here
there’s a valve that I can open into the bucket below this hanged on the dropping
mechanism this bracket here is the same as the foot piece of your drone it’s
coupled to a load cell it’s coupled to that display that’s measuring the weight that is applied to this dropping mechanism that’s going to be hanged here the scale
will report the maximum reading and it will also record all the readings, and samples that are taken on an SD card so that I can analyze that later on for
each dropping mechanism and for each line class and weight class I will repeat it 10 times and we will report on those results so let me
quickly show you one of the experiments this is now let’s take the Gannet Sport
so I will zero my scale I will hang my bucket here let’s make sure it’s empty you’ll see the bucket weighs about 180 g I will then start the experiment and I
will open the valve so water will flow now into the bucket as water flows into
the bucket you will see that the weight the maximum weight will pick up that’s
the current reading that’s the maximum reading and as soon as this bucket drops
the scale will record that maximum it dropped at 532 g what we see there is the last reading while it was released that
was the maximum reading just before it it dropped so this I will repeat then ten times for each weight class and line class and we will report on that, on the
repeatability of this dropping mechanism so let me just comment on the accuracy of the
scale I have got three tested stainless steel weights here this is
333.2 g this one is 201.7 g and this one is 144.6 g grams and you can see
there and then the 201.7 g and then the 333.2 g so here are the results for experiment number one that we’re done in the 300 g range and with a 0.3 millimetre
Kingfisher line as you can see here the dropping mechanisms is shown at the
bottom and let’s take for instance the Cannon 1 all 10 experiments or drops were done between this two ranges the maximum recorded value were 363 g and the
minimum recorded value were 246 g so it was exactly the same setting and 10
experiments one right after the other we’re done this was done exactly
the same for each one of these dropping mechanisms the winner here for test
number 1 on the left hand side is the Gannets Sport for Mavic number 2 the
Gannet Sport and number 3 the Ganner XSport with the Cannon 1 in the fourth place and the one that has done the worst in this experiment where the Cannon 2 so
let’s move to the next experiment this experiment we are done in the 400g range with a 0.3 millimeter Kingfisher line the winner here is the
Gannet Sport for the Mavic followed by the Gannet Sport and in the third place
the Canon 1 in the fourth place the Gannet XSport the one that done the
worst here is the Du Bro with a minimum of 243 g and a maximum
of 497 g let’s move to the next experiment that we’re done in the
800 g range with 0,55 mm Kingfisher line the winner
the Gannet Sport followed by the Gannet Sport for the Mavic and in the third place the Gannet XSport in place no 4 the Cannon
let’s move to the next one this is the last experiment that was done test
number four in the 1.2 kg range and the winner with the Gannet XSport
followed by the Gannet Sport for the Mavic number three place number three
the Gannet Sport in place no four the Sky Rigger with
a minimum recorded value between the 10 drops of 1.219 kg and the
maximum of 1,404 kg with exactly the same setting
so before we look at the final results I’m also going to do individual reviews on for instance the Sky Rigor and other downriggers the PGY I’m also busy
withk so and another thing is I’m going to do lift tests for different drones like
for instance the new Gannett the Cuta copters the Sharcan and so on so if you
want to see those please subscribe to the channel it motivates me to do
these things and I think you also get value from that so let’s look at the
final results and you will see that the Gannet Sport for the Mavic was the overall winner followed by the Gannet Sport and the Gannet XSport all of them basically in the same range the Cannon 1 with 13% average deviation from
from the maximum away from the average and then the Sky Rigger with 17.3% and
then the 2 that came last was the Du Bro and the Cannon 2, so I
hope this test gave you a better insight into the repeatability with a single setting
sitting on different dropping mechanisms I will see you in the next video, keep well! you
