RE: Mixing Glow Fuel

We beat the "by volume or by weight" question to death about 10 yrs. ago in this forum. At that time I surveyed all of the popular brands of fuel and Byrons was the only one that mixed by weight,...

RE: Check my fuel math?

To calculate the percent by volume on any component of the fuel, you divide the amount of that component in the fuel by the total amount of fuel, not the amount of methanol. In your original post,...

RE: Fuji hard to start

I had a similar problem with the Fuji 32ei on my Giant SS. The problem was that the screws that attach the carb to the isolator block were just a tad too long and were bottoming out on the engine...

RE: OK fuel guru's....here is a tuff one

I think that will only get the nitro to about 21%, not 25%. To get to 25% nitro, pour 16.7 oz nitro into 83.3 oz of the original fuel. The resulting 100 oz of fuel will have 25% nitro and about 21%...

RE: Cool Power Fuel

Our club bought CoolPower by the barrel for many years. I always added 5oz of castor or Klotz BeNol to a gallon of the fuel which raised the oil percentage to about 20%. Many didn't add additional...

RE: New Giant GP Super Sportster!!!!!

The manual says to balance it at 5.25", and then, if you want, move it up to 1" forward for more stability and smoothness or up to 1" aft for more aeroabatic performance.

RE: Ethanol Or Methanol? best for Mix? reasons why or why not?

Hey Moe: I'm curious. What type of fuel are you mixing that requires the use of a hydrometer? A specialty fuel for R/C contest use perhaps? I agree with Downunder and Sport Pilot; to mix your own...

RE: Ethanol Or Methanol? best for Mix? reasons why or why not?

Yes, the formulas are correct. Just multiply the percentage as a decimal (20% = .20) times 128 to get the ounces. Example: 128 X .20 = 25.6. I'll bet that there are websites out there with home...

RE: BYRON fuels question

Whoops, my mistake. I should have said that Jeffie's latest post on 1/5/11 and Downunder's post are both correct. I agree with downunder. There is no need to add additional nitro when adding...

RE: BYRON fuels question

Jefie states, correctly, that adding more oil to a jug of fuel will lower the percentages of the other components in the final mix, and explains why...

If the throttle arm on the carb is metal, do not use a metal clevis. Metal-to-metal contact could cause radio interference. I would suggest a ball link on the throttle arm. As for the push rod,...
