The motor mount block is made of 1 piece 1/4 aircraft ply and 2 pieces 1/4 balsa, glue this together. Most of this chunk of wood will get cut out later on.
How to build a strong lightweight fuse
Here is my method, I am not saying it is the best way or the only way, just my way 
You need 1/2 lb to 3/4 lb density foam. It can be bought at Lowes I think it is used for insulating garage doors. It comes 6 sheets to a package for about 5 buxs. It is the lightest foam I have been able to find. It is 3/4 X 13 X 48.
You need some 1/32 aircraft ply and a few pieces of scrap 1/4 Balsa, maybe a few more pieces of wood from your scrap box.

Glue the front spar doubler to the motor block. The spar doubler is 1/32 plywood.

slot your foam and install the motor block assembly. A normal bandsaw blade is just about the right thickness for cutting the spar slots.

ive been useing it too, i calculated that it is 1lbs but i might be off these pics show the landing gear support block and the tailwheel support block installed. the tail wheel block is 1/4 balsa and the LG is 2 pieces of 1/4 aircraft ply with a piece of 1/4 balsa in the center. Also show the front balsa wood to finishing trimming the motor mount.

the finished foam core ready for sheeting. The slot running up the fuse is for the servo wires.

what a kiss ass
Thanks Kenny... Looks like it's gonna be a cool setup.... Final weight is gonna break 4 lbs for sure....Kenny R said:
Spas - It's not my fault that you only get 3 months of flyable weather.... don't take it out on me!!
this year it was more like 3 weeks
That's gotta suck.... Hopefully you have some nice gym's to fly foamy's in.... When I spent a week up there last March, I built a electric foam pizza box to fly around... Did a little flying at the local college and some in the hotel room!!spastic said:this year it was more like 3 weeks
Spas, sorry to hear that dude, I tell ya what, I'll go out this evening and have a flight or 2 for you..spastic said:this year it was more like 3 weeks
It's currently high 80's, partly cloudy with a lite breeze. I would be out flying right now but the tx battery is charging..
Looks good Kenny....evidently you got your work schedule back under control from what it was Makes my own pathetic efforts at putting a bird together look miserable. :wink:

Spas , you might be right about the density I have never actually calculated it . I buy what is supposed to be 1lb density foam to cut my wing cores and this stuff seems considerably lighter, I was just guessing.
dhooks, my work schedule still sucks, 10+ hours a day and 6-7 days a week, I just took off last weekend and got to work on the fuse Sunday afternoon.
I like to tape and glue my sheeting with thin CA, just my preference.
