RE: BVM ULTRA VIPER LEADING EDGE DROOPS NEEDED !!!
Hola Juango,
I've never used Wildcat on my BVM's. I always used Byron 5%, 20% oil blend and they ran good. On OS .91's I've always used Ritch's Brew 11-11 (half castor half synthetic), worked great too. Cool power also ahs new blend which is 100% synthetic which should work great too.
I've never needed more than 5% nitro on DF's. Dude that Viper is fast, be ready to take off and hit 120mph before that first turn during climb-out. I lost my Agressor II when I lost it out of sight before the first turn (tried to trim right after take off, big mistake!). Viper is a lot faster.
Deffinetly hotter than most turbine models. But I wouldn't worry. My first model was a BVM F-16 which was considered "advanced" by most and it was a piece of cake to fly.
Tell your dad I said hi, I will write him later.
