    I think we need to find a benevolent billionaire who wants to die poor. Only way the cost of manufacturing these limited run vehicles could ever be sold at a low enough price to get the kind of perceived market people believe exists. Tim

    Ron, Auto companies have done composite shells with plenty of odd angles and swoopy designs. Using heavy automation, GM's Saturn division pioneered a lot of it; but the only spent a few billion to figure it out (I think the number was 6B, but do not quote me on that). Tim

    I like electric/hybrid airplanes for a few possible reasons. 1. The potentially for radically reduced maintenance induced failure. With so many less moving parts, there is less risk in almost every aspect of maintenance. 2. The potentially for longer term cost reductions. Batteries keep...

    I agree. I think battery tech needs to advance another 25-30% to get to the point where you do not push the battery to design limits on every flight and can therefore extend the battery life for simple training. This is only three to four years away; so having early adopter planes now and...

    @Vigilant1 @Topaz My comment about vibration was in context of @bmcj who stated the fire danger due to wires chafing and other issues are the same between electric and ICE. I was disagreeing, engine vibration in an ICE is significantly worse. And it is this vibration that causes chafing and...

    Good question. How does flying a clapped out 50 year old C172 prepare you to fly to a Cirrus? Bo? A King Air? A TBM? An airliner? I do not think much about the propulsion source except the noise and vibration have any transfer of knowledge... Tim

    ICE has massive amounts of vibration. Said vibration causes significant issues; most of which are rather detrimental to your health and ongoing longevity. Electric motors do not have the vibration issues. Tim

    Your requirements such as 20 year history are in direct conflict with your later statements. Also, consider the Pipestrel and many others the early adopter tax. In the good old USA, the government has abandoned the vast majority of the research and initial development you suggest should be done...

    Not sure this is the same guy. But there was a pretty interesting write up about testing batteries for an experimental ultra light. But when I showed the article an over educated friend (chem and electrical degrees); he said the guy doing the testing did exactly the wrong stuff to make the...

    LMAO, No flight school goes through the TBO hours in two years. I helped finance a couple planes for flight schools (one via leaseback, the other was a proposed leaseback). In the mid-Atlantic you were generally looking around 150 hours a year. In Florida, the estimate was between 200 and 250...

    lol, no. Not sure how many airports I have been too with fuel farms right next to the pump handle. In every case; there has been existing pavement available at the other end of the tank farm or easy to run 100 ft away for the ePlane to park over there. And in many cases, the charger should have...
