    Whale Blubber, what additional additives?

    When boiling down whale blubber for a high quality natural two stroke oil what other additives might be needed to permit ratios like 150-1 or less and still be able to tune ultra lean for maximum performance?

    Let's talk about Avgas (100LL)

    The use of 100ll Av Gas is a discussion that has been around since they started adding methanol to our gas. Av Gas is not good for our engines because they were not designed to use it. The lead in Av Gas is there to prolong the life of valve seats and inhibit detonation in large 4 stroke...

    3W-100 Looking for some advice

    No prob. I was part of all that when it went down. Those were some good engines and I know that a few managed to get waylaid before they ever got run more than the tuning run. Caught a guy shipping some new spares back to home from Iraq. The company was out of Maryland and a couple of the...

    3W-100 Looking for some advice

    Oh my, you managed to get your hands on an old Mako Shark UAV engine. They started out using 3w ignitions but the desert heat turned out to be a little to much for them to handle. Around the middle of 2005 some testing was done and a decision was made to incorporate the DA ignition for...

    2-stroke oil,what works,what doesn't

    Gotta have an oil thread just to assure conflict. Bel Ray oils are pretty "dirty" for our engines, especially when using less than 32-1 ratios. Run lean, either MC-1 or H1R will leave behind a lot of hard carbon due to a breakdown of the chemistry. OTH, the scored cylinder was probably due to...

    The FAA just "went there" NOT GOOD. ALL RC Aircraft = REAL AIRCRAFT

    Some of us have been watching this coming since 2007, when the first ARC committee pretty much shut the AMA out of any activity that would permit them to provide input. OTH, the AMA was a little slow to catch on in spite of what some had been telling them for a year before the ARC thing...

    let us talk about fuel tank clunks....

    In countless gas engine yard equipment products and literally hundreds of thousands of flight hours, one clunk has worked reliably 100% of the time if it was even half way clean. Walbro has been making and providing this filtered clunk for years and it's not limited to keeping crud larger than...
