Airborne Awesomosity, Genius Innovators

The Taylor Mini-IMP

From the time I was just a kid, one of my favorite aircraft designs has been the Taylor Mini-IMP. Looking like the love child of a sailplane and the Douglas X-3 Stiletto, it was everything I imagined flying should be (and still do). And unlike the X-3, the Mini-IMP’s homebuilt availability and prop-driven affordability made the dream seem so temptingly tangible.

The jet-fighter-esque, single-seat Mini-IMP first flew in the early ’70s. The tiny, racy homebuilt was a successful rethinking of Molt Taylor’s stillborn two-place IMP (Independently Made Plane). It featured a pusher prop driven by a mid-mounted engine (usually a 150-200 HP certified aircraft engine or a Revmaster VW conversion) via a remarkablely advanced driveshaft design that used a limited-slip dry-fluid clutch, load-isolating bearings and a flexible disk coupling to avoid harmonic vibration or undue loading of either the prop or the engine crankshaft. It also featured an integral engine cooling fan.
The Mini-Imp distilled flying down to the most pure, unencumbered experience possible. Gross weight is only 1,000 lbs, and you don’t climb into a Mini-IMP so much as strap it on. Molt famously described his Mini-IMP as “The nearest thing there is to a witch’s broomstick.” With its retractable tricycle gear and sleek fuselage, it could reach 200 MPH with a Continental O-200 installed, and cruise at a very efficient 150 MPH with only 60 HP on board. While the flight characteristics are much snappier than the typically sluggish, forgiving Cessnas most low-time pilots fly, the Mini-IMP nicely balanced responsive performance with stability, predictable behavior and reasonable take-off and landing speeds. The fact that the Mini-IMP used fairly conventional construction techniques highlights Taylor’s genius.
Taylor went on to create two more IMP variations, the smaller Micro-IMP (which never flew) and then the even more radical front-engined, rear-propped Taylor Bullet. Molt’s other airplane designs are remarkable as well: the Aerocar[!], the Coot amphibian, and the Navy’s XLRQ-1 Amphibious Assault Glider.

Molt Taylor died fifteen years ago, but the plans for the Mini-IMP are still available from the Mini-IMP Aircraft Company. I’m old enough now to know that I’ll probably never build or own my own Mini-IMP, but flying one remains on my bucket list.

    Reminds me of the BD-5J from the James Bond film Octopussy.

    • The Mini-IMP was everything the BD-5 intended and failed to be: namely, useable.

    • Despite that opening sequence, and the car chase with the Alfa GTV6, Octopussy still manages to be the Worst Bloody Bond Film Of All Time.

      Such a shame that tiny jets rarely come to much, the Microjet is matched only by the Chichester-Miles Leopard in the Rusty's favourite failed tiny jets heirarchy.

        Octopussy is the first James Bond film that I saw in the theater, so it does hold a bit of a special place for me, but yeah it is pretty bad.

        Honda and Raytheon Beech (I think it's them) are building small jets, just not quite as tiny as to be that cool:

        • I love tiny jets. Its like a toy, but oh so much better. Now, to get into high-finance to be able to afford one…

        • I read a flight test of this in Todays Pilot. Very cool, but small to me means fit-in-garage-not-hangar.

        That is a fantastic looking jet.

        Damn my astigmatism – the closest I get to flying is FGFS.

  • Jet-fighter-esque haha… Imagine.

    I'm definitely enjoying this. VLJs and the relatively new LSA class, (Light Sport) are some of my favorite things on earth.

    Cirrus' Vision Jet is something I wish I'd been involved in. If I have the opportunity to work for Cirrus, I'll probably have to learn to live with Duluth, MN weather and do contract work for Arctic Cat if at all possible.
