RC Bugman,

You are correct. We were forced to change from our engine manufacturers oil to Belray due to separation issues under severe operating conditions. I wish to re-state that under the conditions that most R/C engines will ever encounter, just about any oil will work just fine, with synthetics winning out over any conventional oil every time. I'm not altogether certain, but your previously posted oil experiments may have had some bearing in our selection.

I guess I'm one of the lucky ones because of the benefit of having all the available flight data from work to assist my decisions in what R/C products will work the best in my personal stuff. Makes those purchasing decisions easy. All that's left is how much I want to spendto match performance levels.

BTW, the hours noted above are no boast, they're required flying hours and are uaually exceeded.
