Bill,

I used to mix my own DF fuel and I ran 10% nitro, 22% oil and the remaining 68% methanol. If mixing your own is something you are capable of let me know and I will get you the specifics.

Cheers,

5 to 7% nitro will give you best results

The O. S. .91 VRDF really runs very well on 5%. Wildcat is good fuel. I also liked Magnum fan fuel.

Being you're from South FL I'd recommend getting a head shim and running 10% Nitro, the heat and humidity here in the south east is hell on the VR's. the shim and 10% will save you allot of headache and blown glow plugs, after i made those changes mine all ran great even during the heat of summer.

Hmmm....I didn't have any problems running PowerMaster or Wildcat 5% DF fuel in the hot & humid climate here in Houston.
All were OS.91 VRDFs in Dyanamx fans on pitot pressure.
