If it does, it will still break down much faster than the wadding sheets will.
Yep, as long as you don't scrimp and put too little in the tube - I usually put about 3" worth (loosely packed) in my BD, and haven't had any problem with scortched chutes or tether, yet (20-25 flights on it, now).Will dog barf work well in my Big Daddy 3" tube?
Many folks use a little wadding in conjunction with the Nomex shields. I'd imagine you'll be fine as long as the 'chute is encapsulated."an even better answer is reusable Nomex flame shields."
- I have these but noticed that they don't always make 100% contact around the surface of the inside of the BT. Could some of the hot particles get around the nomex sheets?
"Biggest problem I have with dog barf is that it doesn't really plug a large tube very well "
- Please define "large tube". Will dog barf work well in my Big Daddy 3" tube?
Man, that is a good idea.another alternative to FP wadding and Dog Barf are Teflon Tape permanent Wadding "Pom Pom"s. Attached to the shock line the same way as nomex sheets.
Plain old white plumbers Teflon tape is used in 1/2" or 3/4" wide. They take a little time to assemble (30- 1foot strips each) but generally out last the model that are installed in. and can be replaced if ever needed. After recovery simply shake out the Pom-pom and redust with TALC baby powder before restuffing back in the model.
I've used them extensively in sport flying models BT-5 to BT-70. Gererally you only need one for BT-5 thur BT-50 models 2 to 4 in models Bt-55 to Bt 70
I've been very happy with their performance, with them I've yet to melt or scorch a plastic or Nylon chute.
I agree... I've noticed that a lot of folks that gripe about getting burned spots on their chutes with dogbarf (most not all) are usually not using enough... From my experience I'd say use enough barf to make a plug at least the thickness of the body tube diameter, (IE about a 2.6 inch long 'plug' of barf on a BT-80 rocket) but probably half again that isn't a bad idea (say about 3-4 inch plug of barf on a BT-80 rocket) if you really want to be sure you don't get scorched. Also I've noticed that 'packing' the barf a bit into 'plugs' seems to help on larger rockets-- leaving it fluffy lets it blow apart too much and particles to 'zip right through it'. Ya can't pack it like ramming a bullet down a muzzleloader rifle or it may not deploy, but a light 'tamping' once it's in the tube isn't a bad idea.Yep, as long as you don't scrimp and put too little in the tube - I usually put about 3" worth (loosely packed) in my BD, and haven't had any problem with scortched chutes or tether, yet (20-25 flights on it, now).
TMI, Luke, TMI!Geez, I must be getting old... starting to sound like my grandmother, who, having lived through the Depression, used to REUSE TOILET PAPER!!! (No I'm not kidding!)
