Dynamite .32 / ThunderCat 31

[Troy Thomas]

I just purchased my son a ThunderCat 31 and was wanting to know what the best glow plug is for this .32 size engine running O Donnel 50% Nitro? The manual sais DYN 2508 which is a MC 59 but that is for 20% Nitro.... Thanks for the help...........

Thanks guys, Robert i got your message! I know some use the cooler plugs with the higher Nitro but i tried running a #9 in my OS outboard at 50% and it got to rich so i went back to the medium #8 OS plug and thats what it runs its best with. I figured there would be more people running these .32's that could tell me if a medium heat plug would be to hot for this engine at 50%. I just purchased both medium and cold so i will try it with both...... Thanks

Try the Mccoy 9s or Odonnel blue plugs
