Telescoping ladders take up less space and may weigh less than the version above
Yes, but what would you lean it against?
How would you check the TRGB oil level on a high-skid 206 - lean it against the tailboom? Or maybe lean it against the cabin to get up to the M/R head.
The best thing I've seen is a four-step folding stepladder that weighed about 5lbs, and fits inside a 206 boot. You can reach the kick-in step on the 206 easily.
The 7:1 Multi-function job looks way too big and heavy for carting around in a small helicopter.
