Title: 20% nitro?
Post by: Dwayne on April 19, 2019, 05:45:35 PM

I'm having a hard time getting 10% at my  LHS up here in Canada,  a friend went another Hobby shop over 100 miles away to buy some things for others and himself, I asked if he'd pick up some fuel for me but came back with 20% instead of 10%, I'm flying a K&B 28, Webra 32 and LA 46, would 20% hurt these engines?
Thanks

   Very unlikely to hurt the engine. But I also assume you can get FAI fuel, so 50/50 gives you 10%

I run 20% in my os 20, 25, 40 and 46 every time I fly. I haven't had issues.
But, like brett said. Mix FAI to get 2 gallons of 10% and it might end up being cheaper than having bought 2 gallons of 10%

Dwayne,

Try the local Home Depot or CTC store and pick up some methanol. My local CTC carries it in 4 litre jugs . The last time I was near the big smoke (Toronto ) the Great Hobbies store had both castor and Klotz. Mix up some 80/20 or 75/25 using your choice of oil and then turn your 2 gallons of 20% to 4 of 10% with the proper amount of oil .
