Me too, Roy.
I first became aware of Burt and Dick at the 1973 California Air Races at Mojave. Burt built the Vari Viggen and Dick flew a spectacular air show with it. The canard delta winged airplane had some really neat flying qualities and Dickbexploited them well. High alpha and low speed cornering being what I recall.
So long, Dick.

I used to run castor but in the LA 46 I found better runs from no castor. I used Powermaster 15nitro , 18oil , and found the needle much steadier than custom blends with castor. I changed over time coming to this conclusion, and compared flights on the same day after consulting experienced guys like John Hill and Joe Gilbert.

Kafin, your math seems correct on a gallon basis.

The OS 46LA owner's manual recommends 20% oil but also says do not go lower than 18%. And the manual says full syn can be used but is less tolerant of lean operation.

I would add the castor. And be sure no not set the needle too lean on the ground.

The following is on a quart basis (multiply by 4 for gallon basis). To add castor to the mean and green fuel:

For 20% total oil, the mix would be 31.2oz of fuel / 0.8 oz of castor (resulting in 12% castor in the fuel blend)

For 22% total oil, the mix would be 30.4oz of fuel / 1.6 oz of castor (resulting in 23% castor in the fuel blend)

I would use the 22% oil blend. I have run LA's at 23% oil in the past (Brodak fuels) with no issues. I currently run my LA's at 20% total oil (32% castor/68% syn).

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. 😉

If it were me I'd sure add the castor oil.

« Last post by Kafin Noe’man on May 08, 2024, 06:23:42 AM »
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've run several gallons of castor from Bulk Apothecary it's very good stuff. Lots cleaner. I mix it with Klotz Original Techniplate 50/50 in my home brew.
