Just finished my TF P40e. I've been reading some cautionary threads on the tip stalling characteristic of the TF model, and moreover several threads on the robustness or otherwise of the Robart twist and turn retracts.
It's all making me rather jittery.

However...
I've noticed a loss of pressure from the air system without exercising the retracts and am concerned even more. The links and attachments have been double checked but it still loses pressure.
Have others encountered this, and at what pressure do you operate your Robrats, oops, Robarts?
