just curious if you know if these plugs are for the fox.07 too? ex engines listing only says for fox 049 but Im almost sure the fox 049 and .07 use the same crankcase just not certian. I have 2 .07's and thinking of putting one on my norvel vision(cox katydid copy) thanks for any input cant find much info on the .07

The Fox .049 and .07 use the same plug. The problem with the Fox plugs is that they fail with regularity and are very undependable. I truly believe it's mainly due to Fox using the thinnest wire available. The plugs glow practically white. Now the weird thing is that I have knocked out the post on the stock Fox plugs. I drilled and tapped for a standard plug like the link that Eric shows on RC Groups. The engine ran better than the stock plug. After I tapped the plug hole, I took a cut on the top and sunk the plug so that the plug was flush with the combustion face. I truly believe this is why it works so well.

Bob Matte Free Flight Engine Rework can also provide you with a ring that threads into the Fox cylinder but utilizes Cox glow plugs. This would enable the use of Nelson head adapters or turbo head adapters as well. You have a fair amount of options. The next problem is when the crankshaft blows apart and then you have to find another.
