I have 3 planes I'm putting gas engines on that I decided I wanted to go with the stand-offs that look nicer. I'm just undecided because I need one to be 35mm Which in inches works out around 1.375" and the other is almost 1.75" Which I could combine 2 sets. For $25 I can order them custom length. With the wood ones I cut out of dowels I use washers to set off-set for thrust or any added distance.

The one you showed Beteos will work for the one and a great price. Thanks
