Guys don't mount the vertical inside the slotted tailboom. It will snap off
on a spin landing..immediately.
Then you will have to clean off the remaining boom from the mount area. Slot the mount area so that it fits over the remaining unslotted part of the boom, then you'll have to cut lose the Elevator mount and futz with the pushrods. Instead when you are in assembly, slot the rudder mount area to fit over
the end of the boom. Cut off the edges of the boom that surround the
slotted part, and mount the vertical over the end of the boom. Make the
slot all the way to with in about 1/4" from the hinge line.
Make sure you slip the elevator V mount on to the boom before you glue on
the vertical to the boom. Okay to use medium CA for that. but don't make
too big of a fillet at the edges of the slot in the vertical. You will
then cut some short strips of 1/5 oz glass about 1/4" wide to make the fillets
at each joint area on the boom. Spray the strips lightly with some 3m
spray glue, kind or brand doesn't matter. When they are tacky, press each
strip into place and use your thumbnail to get them seated well to the boom and
mount joints. Then use thin CA in a couple of controlled coats to treat
the cloth and joint.
It makes it as bullet proof as the material will allow...really secure for rough use. Do it the way the boom was sent to you will end up in heart break and down time. And no its not likely to change from the supplier. He 'feels' that
slotting the boom is a good idea... its a translation thing I think :-)
Great sailplane modified for USA use :-)
