Nickolas:

Thanks forthe info...i can not download the manual of the OXALYS it doesn´t download completely, i dont know the reason i hava good computer and the last version of the ACROBAT.
Well.....so let me see if i understand you.....you told me that i can put the pipe over the wing and then over the pipe install the belly pan?? is that correct? or to glue the belly pan and then cut it until i could make a tunnel bellow the wing?
I can buy the YS 63 but i already have an almost new YS 45 with a hatori pipe and it is a very good engine, that the reason i am asking because i need to make a desicion very soon!

Thanks again, i would appreciate more pictures of the bellypan
