Yesterday went out to try some new TJ models CNC aluminium props I just got from Ian Folkstone of Ian's Boats.
I got in 3 sets of left and right hand rotation to use on my HPR 115 cat.
The series I got are called 1218, which look very much like Graupner K series and Octura X4 series.
The props come balanced and thin being CNC machined, so if you damage one the replacement is the same.
The props give a lot of lift, then onto the trial. Compared to running X442 the TJ 42mm made the cat run quicker and slightly more stable. Then onto the 45mm, it will be a fight take these props off the boat. Still accelerating on the straights at ELmbridge before I have to throttle back to start powering around the turn.
So go out and get your CNC props ! Reasonable price (£75 for 6 props), balanced, thin and light.
Cheers
David
