RE: Aquacraft Super-Vee 27 Nitro.
No Dash, it's the low oil content. Boat engines last longer with 18-20% oil where plane and car fuel don't have that much. Heli fuel is the closest plus you can find that up to 30% nitro.
The LHS's should be able ot get it now as Tower/Great Planes carries Aquacraft Grimracer O'Donnell fuel so they can get it there
