on all of my HOB 1/2 kits I dont use the 1/32 ply for the fus at all just adds weight. these kits are over built in the fus.
lighter flies better. also I forgot to add E flight has or had some small air retracts also.
these are the same ones made by Sapac or the same ones Sapac carried. I have this set and a tri gear set for the bonaza. i have used these in a Sapac Viper jet. it was 4 lbs and held up well even in a off the paved runway into the grass landing.
