    Yamaha Apex internal gear reduction.

    After careful consideration.I need to make a block that the ordinary person who can afford a nice boat can afford an airplane that is safe and has decent performance numbers.The Yamaha engins will work and are reliable.To me they just are not where we as humans can fly.I want to go a total...

    Why has not anyone used the one out of the jetski version and put a gear reduction on it?That one does not have an internal hear drive.Already has some kind of torsional dampner on it too.

    Yamaha Apex internal gear reduction.

    What I wanted to do was use the internal gear reduction because I can make gears to get the rpms right.The problem is the face of the engine will have to be redesigned also because there is not enough room for the larger gears.

    Yamaha Apex internal gear reduction.

    Getting ahold of one of these apex engines can not come soon enough.I have been looking at images and documemts,but actual hands on measuring is going to be the way to go for me.Machining a whole new block is 5 grand.I am hopping there is enough on the face of the block for me to work with,but...

    Refridgeration engines on refrigeration semi trailers are 100 hp and run on diesel.They are a V twin design.I always though one would work great in a motorcycle.I have had some that where in excess of 44,000 hrs.They do have a huge base plate on the bottom of the engine that would need to be...

    Are these also the ones with 2 magnetic triggers on the fly wheel for use with the Ducati dual ignition?

    Well it must be really stupid because I do not get the reference.Care to explain?Because I am not into social anything

    Yamaha Apex internal gear reduction.

    So far the Apex engine is beating all other alternatives.Power to weight and cost being the most important to me.Looks like I am going to end up with a sled and a jetski.I.can at least have some fun on them before they give up their engines.Time to talk with some machinists I know and see what...

    Lived it.I have been in many situations where what looked good on paper to an engineer did not work in real life.Never trust an engineer who does not have grease under their fingernails.

    This radial is not a diesel,but radials fit aircraft really nice.https://youtu.be/SyRJeZ6s8uM A radial diesel would be awesome!

    I am partial to diesel engines.They would eliminate the need for dual spark ignition and by nature are lower rpm engines.😃

    Yamaha Apex internal gear reduction.

    Good stuff I love it.For me the engine is the hard part.I am confident I can build a plane of my choice from plans.The Model A of experimental engines I beleive would make more dreams come true for people wanting to fly.My Freight Shaker is a 10 speed although I wosh it was a 13 speed.The jump...
