A buddy burned up a 46AX that was a couple of months old trying to haul a long streamer at top speed. Two things needed to be changed to make it work.

Trying to go flat out isn't the best choice. Using a flatter pitch prop than the one he'd chosen for daily flying would have helped too.

The bigger you go, the less impact your banner will have.

I fly a number of warbirds that were designed for 60 size glow. I use 90s to swing a bigger 3-blade. (They are the same size and almost the same weight.) The 90s have half-again more horsepower than the 60s. If I had to choose an engine to pull a banner, I'd pick the 90 over the 60. And I would bet on the 90 being able to do the job.
