* Prototype was all metal
* Two 100 HP engines, and I think fixed pitch props
* Fixed gear
* Tandem seating (possibly single seat, don't remember)
* Ailerons had an unusual boost system using tabs under the wings
* Not sure, but I think that the engines were on a stub wing like the Dornier Do28

Thanks!

Bingo! Thanks. Speedtwin Developments » AIRCRAFT Looks really stupid with winglets, but who asked me? The new version has two, 205HP Titan engines, according to a 2012 article on their website. The current model is the "Speedtwin Comet." Only found one youtube video -
Wonder what the single engine handling is like, and Vmca? It does have a dorsal fin which may or may not have been an add-on.

Keep in mind it's also a tandem cockpit. Engines are much closer together than normal. Vmc might be at or below stall speed.

OMG I don't think that seeing this aircraft being thrown around in aerobatic manoeuvres from a great distance to the most appalling loud rock music is the way to sell this aircraft into its target markets. I don't think that many military or government procurement specialists are really into that kind of scene, or anyone else actually except teenage flightsimmers and prepubescent Youtube fans.
If I was them I'd be showing something of how it's built, how strong and easy to maintain it is, how the engines are beautifully installed with easy access for maintenance or repair, how spares are easily and cheaply available, cockpit views of the panel and instruments with an idea of the alternatives that are available depending on aircraft mission and cockpit videos with commentary showing how easy it is to fly and how manoeuverable it is. But then again what do I know.

I agree wholeheartedly about the use of the appalling 'music' which could have been replaced by a commentary on the handling, manoeuvrability and its single- engine handling could have been demonstrated, providing airspeed information as well as some detail on manufacture, maintainability, etc.

I knew the designer, Peter Phillips, an ex-Hunter pilot and a world class aerobatic pilot, so the Speed Twin was always going to be an excellent aerobatic machine. The prototype used the wing panels from a Victa Air Tourer, which type at one time Peter was contracted to demonstrate around the UK. His demonstrations commenced with his signature low-level 8 and 16-point hesitation rolls, which he also flew in the Tiger Club's Cosmic Wind in which manoeuvre he vied with Neil Williams when practicing for the World Aerobatic Champs in the 1960s.

Just the thing for those budding Mosquito pilot wannabe's.
I know the aircraft started off with the original Victa wing and tail, I just hope they beefed it a bit to go swinging engines off the wing :oops:

Another perspective:

Not really “thrown around”, all low, positive g maneuvers that can be done with almost any spam can.
That was lousy music; any decent real rock music would be much better. They did allow the aircraft sound to come through the music.
Curious about single engine handling and performance - guessing that it is good.
If really intended to teach upset recovery, would like to see single, critical, engine spin recovery.
To be a complex, multi-engine trainer, or to be a viable candidate for almost anyone’s government to consider, it will need retractible, tricycle landing gear.

It would be a great E-AB.

Indeed a retractable undercarriage would improve it at some cost, although reasonable fairings on the fixed gear would help- similar to a those on a DH Rapide. That might require a longer dorsal fin though.

Backward retracting wheels into extended engine nacelles - beyond the TE - might improve it aerodynamically. Being unashamedly old school, I prefer the tailwheel layout, but I agree that today a tri-gear arrangement might be a requirement in order to sell it. Single engine performance is described as good. In plan view I am reminded of the F-7F.

The original version had faired main gear. A big set of Ryan STA/Stuka/Val looking spats. I thought they looked really nice.

Just to be clear, were I to magically acquire an E-AB version, I would want the tailwheel and faired fixed gear.

But I don't think that such a version would ever be purchased by a military or other government entity, either here or abroad.

I agree about the winglets. I hate the paint too. The original one was beautiful in solid medium blue.
Agreed, those winglets look silly on a low aspect ratio wing, but some people prefer winglets for "styling" reasons. .

... kind of like BMW's decision to add shiny, blinking lights on the corners of their cars. Since nobody uses turn signals in Vancouver, adding blinking lights is purely a fashion statement.

The winglets look ridiculous. Perhaps tip tanks would work almost as effectively as endplates to increase the 'aspect ratio effect'. While they're at it they could use one as a a radar and the other as a laser tracker to aid target acquistion for an underslung, centreline cannon.

Just saying'...
