Nigel ... let us know how she goes, I was about to do the same as you, as I have a 2W-25 ... all the best.
flown the funjet tonite using an apc 4.75x4.75 prop.
found to be a tad slower than using the 5x5. temps where around the same also duration wasnt any different.
either/or prop seems to work well.
give your set up a go. you wont regret it!!!!!
