No matter how you do it plywood sucks. It is going to be slow. Rigging a tail sometimes helps it fly a little straighter. Just go slow.
Poles: depends if you have to set them or not. rig a cross bar at the top and attach from either side. I have flow tem with just one chocker or horizontal with 2 chokers.
Cabin, com shells, etc. Four points , make sure the rigging is strapped together so the structure cant tipp to one side.

For plywood sheets, stack as many as possible and secure with ratchet straps. Rig from all four corners to the central lifting point. Make sure that the strops are equally loaded otherwise the load will oscillate horribly. This works fine but take it easy as obviously a horizontal "slab" load can always give problems.
The problem with cabins is securing them, particularly if they are ply. I have tried various ways of rigging but the best always seems to be a net if it is feasible to get them in and more importantly out again.

Thanks for that link, it's a great resource for newbies and instructors. I guess you use it all the time in USA but it is not common elsewhere. It just shows there's masses of info out there, we just need to find it...

The various agencies that use the IHOG as a basis of operation have actually done a very good job on developing a broad and inclusive guide to all types of utility support operations. The other Chapters really offer a very comprehensive guide to every aspect of utility helicopter operations - and best still, they actually explain WHY you do things that mitigate risk and eliminate problems.
When you consider that the majority of personnel involved in these operations perform some other function for 97% of the year, and essentially know very little about helicopter operations, you must have a detailed system to train and operate from. The nice thing about the IHOG, is that not only does it provide practical real world advice, but it also forms the operational basis for every one of these functions. Better still, it's free!
There is a revision out, but it hasn't made it to the website yet - so keep an eye for an update.
