Props for gassers
I have the TF giant scale corsair, G62 engine.
I'm using a TF 20x8-14 prop because it was recommended to me.
Can someone explain the 8-14 part of the prop size?
I'm used to a 20x10 lets say, does the 8-14 refer to pitch as 14" by the hub because it travels less distance, and 8" at the tip because it travels a longer and faster path at the tip?
Is this better than say the 20x10 prop?

the prop has the lower pitch near the hub, because there it has to operate in near-stagnant air in front of the cowl.
It also saves the prop maker a lot of wood, because the billet can be a heap flatter!

Pete S-RCU,
I use to use a XOAR 22X10 prop on my G62 but have since switched to a Top Flite 22X6X10 prop. With the XOAR 22X10 prop I was having trouble slowing the plane down on landings and the 22X6X10 prop helped plus it pulls as good as the 22X10 and best of all it makes a great sound in the air. With the XOAR 22X10 prop I was getting 7000 rpm and with the TF I'm only getting 6500 rpm but the power seems the same and once again it makes a great sound in the air.

RE: Props for gassers
Thanks for the answers guys.
I have the engine in a TF giant scale corsair.
I also have an APC 20x10 I was going to use for breakin, I may try that till I can get a new prop.
The corsair seems hop a bit on landing, would the 20x8-14 slow it down more for landing or would the 20x10 be better?
The two props look a lot different, more blade area on the 20x8-14.
