There’s loose screws on the muffler. I was also thinking of putting a gasket in between the motor & muffler, good idea?
I will definitely have to go over to see if there’s any lose screws on the motor as well and try to fly it with 10% nitro fuel.

No gasket should be required. I know the stock muffler comes with Phillips Screws. Don’t remember the size but if you can find hexhead cap screws to replace them they won’t come lose as often.

You should get in a habit of checking all screws and nuts from time to time. Just like real aircraft they require maintenance and inspections. You have a vibrating flying machine. Things vibrating lose is a bad thing. 😉

I had ordered a gallon of VP Powermaster 10% Nitro 18% Oil (Air — which is a castor/synthetic blend 20:80), but unfortunately they didn’t have that anymore and just sent me the Mean & Green one which I believe this is a full synthetic.

I’m going to use the fuel for my LA-46.

So the question is, can I use that Mean & Green fuel as is?

I’ve also been thinking to add some more pure castor oil (I can find Merlin Castor Oil MA-220) in order to increase the % of oil to 22%. If my math is correct, I need to add 194 ml (6.5 oz) of oil and doing this will make a 22:78 castor/synth blend.

What do you guys think about it? Should I return it or just proceed with adding more castor oil?

I will have about a dozen OS-FP & LA engines available at Joe Nall.  These have my rework and tongue mufflers $125 each to $150 each.  Also, a few G-24 ST46’s.  I’ll also have some of my profile kits and a few planes for sale.

For more info, contact me at 770-592-3279.  I will be at Joe Nall about noon on Thursday, May 16th.

See me at Brodak’s too!

Hi Kafin,
I run an LA-46 on a tongue muffler (all holes open) in my Vector 40 with 5% nitro, 20% oil mix and a 12.5 X 4 APC prop. I have tried a couple other fuels (5% nitro/18% oil, 10% nitro/18% oil, and 10% nitro/20% oil) and had either power issues or overheating. I've found that with the heat and extreme humidity in our climates that even seemingly small fuel changes can throw the motor run off.

Before takeoff I set the needle to where the motor is in 2 cycle and just cracking into a 4 cycle every couple seconds. The lap time is around 5.1-5.2.

Hi Jake,

Thanks for sharing your thoughts.
Why did you decide to use 5% nitro fuel instead of using the 10%? I thought with the heat we have here it will be better to use 10% nitro.
I’ve been using 5% nitro for the past year but I was thinking to switch to 10% nitro.
