So who has an Ace Ultimate bipe and what wheels are you using? we fly from a decent field and with a .25 it should take off from a picnic table but my 1/2a experience with landing quite often leads to "pranging" upon landing and if this thing lands fast then that would lead to "fast pranging", which doesnt sound like much fun...so what is a good size wheel?..Rog
I may not go with a .25 maybe a .15
Hi Rog,
I got your PM, but I see you asked the same question here, so I'll just answer you here.
IIRC the kit came with wheels, and I think I went up a size. The main thing that helped with flying off of grass was to move the landing gear ahead a little bit. Here's a pic, looks like about 2.25" to 2.5". It originally had a Norvel AME .15, but that engine wants to spin a small prop fast, so I swapped in an OS .25 for more pull.
