I've started working on the Big Daddy I rec'd as a gift for Father's Day (how appropriate). The thing is practically all nose cone....
I'm building this one up to be a workhorse for my RMS 24/40.
The modification I'm thinking of doing is to replace the BT50 engine tube with a longer one that will go up into the plastic nose cone like a long stuffer tube. I'll enlarge the existing hole in the bottom of the nose cone so the BT50 tube will fit into it. The idea being that the ejection gases and particles will go into the nose cone and protect the chute/shock cord like a baffle.
My concern is whether the plastic nose cone will be OK. Are little burning chuncks going to melt a hole in it? The plastic is fairly thick. Or would it be prudent to try and coat the inside of the nose cone with epoxy....or a layer of foil...or even stuff a "Chore Boy" up in there.
Has anybody done this modification to their Big Daddy? I seem to remember seeing this sort of thing done to a Fat Boy.
Thanks,
John
