Geocaching is where people hide things and then post coordinates on one of several sites (e.g, http://www.geocaching.com). I have actually incorporated this in with my TI trips as there are several scattered about in the 10k islands.

You have been basically geocaching for your Mavic.

...
I really need to get an OSD and telemetry added, but didn't want to spend the extra $200 on a good one (OSD = on screen display - transmits info back to my goggles). I'm building a hex now so I'll probably pony up.

Glad you have a system like the Mavic - it is top of the line.

Totch, you are right...I've been combining drone flying with Geocaching!

BTW, what goggles are you or will you use?

Right now I have Fatshark Attitude goggles. As I finish building out my hex I am thinking of moving over to Fatshark Dominator V3's for better resolution. If you are thinking of going goggles, you may want something like the Dominator. It has a port where you can pop in different frequency receivers. Whereas most fpv video tx / rvrs operate at 5.8Ghz and the drone control runs at 2.4ghz, I believe dji does it just the opposite so you would want to have a 2.4ghz video receiver.
Check to make sure though, things could have changed or I could have dreamed that up.

I fly through and around the woods a lot here in Georgia, so I'm looking to go with the new 3.3 ghz video tx / rvr from Iron Horse. I'm hoping to get better range through obstacles with it. Only problem is Fatshark doesn't have a 3.3 ghz plug in receiver for the Dominator, so I'll probably have to rig up something ugly.

Drone building can get expensive and complicated! I should have just bought a Mavic!

Are you having any problems with restricted areas? I heard dji just issued a firmware upgrade that went crazy on geofencing.

Thanks for all the info Totch. I'm really a novice when it comes to goggles.

My backyard is 4.5 mi from the local airport, and there is a heliport at a local hospital about 3 mi away. I get a warning each time I fly in my yard and must confirm that I am responsible for flying here, but, other than that, no problem.

Might want to be careful upgrading the firmware. I just read an article that once the upgrade is applied, it will not fly at all in a restricted area.

Technically, if you are within 5 miles of an airport you can fly if you get permission from the tower, but dji has gotten more strict.

Totch--here is an article which describes my experience, i.e., except for certain red zones, the operator decides whether it is safe to fly in an area.

I believe that picture was taken at one of the WaterTribe Everglades Challenges. Personally, I think that fix is ridiculous. There are better ways to fix the front hatch leakage problem without sealing it semi-permanently. Having said that, I agree that Hobie should do more to remedy the problem.

Keep-Out Lines Revisited

Anyone who does serious day trips or multi-day camping trips needs keep-out lines. Any keep-out line which (1) attaches to the hull and (2) angles back to attach to the ama, must be able to stretch to absorb the shock of a collision of the ama with an object. The aka brace pin will break, but the keep-out line will prevent the aka/ama folding back. As Fusioneng has said, even multiple small shocks to the ama will add up to sufficient wear on the aka brace pin to ultimately result in the pin breaking, ama/aka collapsing, and, perhaps, “insta-capsize.” The keep-out lines are designed to prevent the collapse.

My keep out lines are simple: a hard line connected to a short section of bungee cord. The bungee cord provides stretch allowing the aka/ama to fold back and permitting the aka brace pin to break as designed.

Image


This picture shows the shock cord stretched.

Image


You can apply enough force on dry land, to fold the aka/ama back considerably.

Image


When not in use, the keep-out lines are simply stored on the ama.

Image


Those original flat bungee cords did not stand up to Florida sun and elements. I have replaced them with 19” flat, EPDM rubber bungees. Amazon link: https://www.amazon.com/gp/product/B000CCFCO0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Image


These keep-out lines have been tested at 8 mph on the water, and they prevent the aka/ama from folding back.

How did you attach the eye straps to the amas?

Hi Mistermoon,

I just drilled a small pilot hole into the ama and then used a SS screw. I think they will hold anything barring a major collision, like with a piling at speed. They do not leak into the ama.

Thanks. I'll take it under advisement. I'm not super comfortable drilling holes in the amas, so I think instead I'll tie the ends of the hold backs to the akas.

Why do you assert that the hold backs must be able to stretch to absorb the shock of a collision of the ama with an object? I need convincing that's truly necessary. I plan to test it with 3/16" nylon (stretchty) and 5 mm dacron (doesn't stretch much) to see what works.

I have no problem drilling holes in plastic amas. Just fill them with goop or a fat screw. It is plastic and will flow to close tightly around a tight-fitting screw.

Some kind of stretch is necessary. If you use a non-stretch cord, you have a rigid system and the pin will not break transferring the forces to the next point of weakness. At the other end, you have my bungee system, which gives, allows the pin to break, but doesn't allow ama collapse with insta-capsize. In between is everything else.
