Putting the UH1 onto the trailor, the pilot probably isn’t looking right back at the heel of the skid, you just have to lean out too far to do that.
you simply have a mark where either the front cross tube or step goes, and as long as you are straight while landing it then all good.
our Huey trolleys have a mark for the step, as long as we line that and are straight it’s all good.
best bit of advice I have been given would be to stop using the cyclic to move the helicopter and start using the pedals. It really helps with long lining and short sling work as well.
