I need some help with picking the right prop for two new airplanes.

1st is a U_CAN_DO_3_d with a super tigre .90. I know I won't have a lot of extra power so I was thinking a 15*4 APC.

The 2nd plane is a Magic 300L by modeltec with a HP .60 on it. I have the 1st magic with a webra .40 running a 12.25*3.75 and am very happy with it. I have no Idea how to prop this .60 for funfly.

I want to hover both of the planes, Thanks for any help or suggestions you might have.

put a 13x4w on the .60
maybe a 14x6 on the 91. not sure

aiming
i agree with king go 14/6 for the ucando
with the magic i wouldnt put a 60 on it..i have the magic xtra...i have a 46 magnum with a macs one piece muffler,running the 12.25x3.75...on take off i roll no more than 20 feet and i climb vertically until my neck is tweaked..i hover this aircraft at 1/2 throttle..to put a 60 on it would require some major engineering..you may be up for that. if i had to guess what to prop to run with a 60 it would be 13x5-13x7...somewhere in ther would be good for 3d flying...good luck
