Avionic trailer.

Hi

I bought a new Avionic trailer in 2016 for my DG-808B
I haven't only done 1 rigging / derigging with it, but have done countless similar operations with Cobras or Schroeder trailers.

There are indeed differences with Cobra trailers:
1)
The first one is the door at the back which is not (and shouldn't be) used as a rest point to stabilise the trailer. You have to deploy the "crutch" and make sure the door doesn't support any weight as it's not designed to do so (2 smaller hinges compared to door wide hinge on the Cobra).
You also have to make sure the door is far enough from the ground not to damage the wing supports located on the inside of the door. They're longer than the door and can easily be damaged.

2)The central rail on the ramp does not fold sideways. There are two additional central ramps that are store on the side of the trailer that you have to put in place before use.(main, and last ramp that guides the tail to the ground.

3)The wing dolly can disengage from the ramp if you're not careful or too quick in the manoeuvre.

4) I ordered a "luxury" version with aluminium floor and aluminium top. Not sure Cobra has an option for aluminium floor ?

Again, this might not be true for all types of gliders (wing supports on the door for instance...), this is only reflecting my experience with an AVG18 and DG-808 with wing parting.
My advice would be to double check with the factory that they have already the exact dimensions for your glider and accessories before the manufacture is started. If not, send them the info.

I'm sure the factory will take these differences and inconveniences into account and try to improve their product.

All in all I'm quite happy with it. I don't think the higher price of the Cobra is worth the difference, unless maybe you have to rig at every flight.

In conclusion: I would definitely recommend an Avionic trailer.
