Default os problem

i have a fairly new os engine after brake in it has not even a half gal through it
my problem is this thing is eating glow plugs like it gets paid to do it
it ate 3 glow plugs during brake in but i figured its just really rich so i didnt think too much of it now its all tuned its running right around 200 deg F has decent power idles fine starts up hot or cold in about 3 pulls so i know im not cooking the glow plug
ill be running the buggy and ill realize power is starting to fall off a little (less punch off the line) itll either eventually die out at a idle or ill shut it off and it wont start ill pull the glow plug and shure enough its either dead or its bearily glowing ive ran about a half gal since brake in and its just eatn its 4th or 5th glow plug
ive tried os plugs dynomite and some traxxas pulg that my buddy had (it had the same reach as the ones im using)
i dont think its running too rich it has little trail of smoke from the exhaust but nothing excessive
the engine is the os 21 RG the pull start version of the VG
the fuel im running is 30% odonnell
any ideas?

I've seen the VG eat plugs. I have never seen a VG really take a good race tune and stay running fine with out overheating or taking a dump by eating the glowplug. From what your describing though, the mixture sounds lean, or is going lean. This motor uses a nickel sleeve which does not last long at all under these conditions. IMO, your better off going with a VSpec or JX21 in the OS engines series. Or unless you really want it, the Speed is their best motor.

If it's the RG, it has NOTHING to do with the VG. Sounds like an overly lean tune, or incorrect head shimming.
