Are fireball glow plugs any good? I have seen some good buys on the fireballs but have never used them.

I've read replies on RCU from people who have been using them for years in two and four stroke engines.
I asked about them at the club and one person said he tried them and didn't like them.I asked why and he said they ran good for several flights then would go out, causing a deadstick landing.

Every brand has fans and critics. I've used OS, Fox, and Tower in my TT61Pro. All seem to run fine.

I have used Fireball plugs with good results and no problems, though Fox plugs remain my all around favorite.
