RE: Red Arrows Hawk ARF - Which Engine/Fan ?
As Vinny asked: What is the weight difference in adding a Dynamax and .91. Another pound or so?
Larry Wolfe (the US importer through JHH) flew his routinely on a .46/Turbax reliably and fast! and I had the oportunity to fly his original one with zero complaints on power!
Oh...this was also seen in Denver, at 5400ft.
Save the weight, go with the .46/Turbax.
(my 2 cents)
