- My rule for glow plugs is to run the cheapest plug that gives a reliable
- idle, strong top end, and little chance for a dead stick. Sport engines
- with mufflers can usually get by with a $1.50 Fox idle bar plug. Add
- a tuned pipe and I go with a Rossi #5 or #6 to get good plug life -
- Fox plugs would only last 1 flight. Run an inverted engine with
- muffler like a YS 45 and I use an Enya #3, which gets a drastic improvement
- in idle. The Rossi plugs go for about $3 and the Enyas cost about $6.
- For my 4 cycle YS 120 I run an OS -F plug, which costs about $6. If
- you've got very short plug life with a cheap plug, replace it with a
- better (more expensive) plug of the correct heat range. You may find
- that the expensive plug is actually cheaper in the long run, i.e.
- more flight time per dollar spent on the plug.
