Five Twin Engine Aircraft Nobody's Heard of

[@eddcla7766]

Yaaaaay! Love the Speedtwin, thank you for all the information on it, most of it new to me. I always wondered what happened to the project, and if they might not have been better off (at least from the perspective of number of airframes flying) sticking with the plans-built approach. Really wish someone would pick it up, so much potential.

[@aircraftadventures-vids]

Happy to help!

[@xpump876]

Ditto to the enthusiasm on that SpeedTwin - what a cool bird!

Great educational experience. I’ve been an aviation fan all my life but never heard of some of these planes nor their history. Well Done Sir.

My dad flew on the Rockwell 700 once to a project for Cedarapids, Inc (now a Terex brand). Many years later, but before 2011, I spent a few minutes on board inside a hangar. It was very nice.

[@jamesbooth3360]

The Cessna T303 was a great airplane and belongs on the list of seldom known light twins. Flys like a 182, FL250 capable, ergonomic panel that makes it very easy to manage, trailing link gear, and a very comfortable aircraft for passengers. Only produced for about 3 years and sold for 4 in the early 1980's.

[@aircraftadventures-vids]

It is a nice plane for sure, and I think I've already added it for an upcoming video.

[@johnwighton]

My company did a lot of the engineering work on the mk2. The project owner, Malcolm was totally unrealistic and inexperienced in light aircraft development. Sufficient to say that we parted company, Speedtwin Developments didn’t pay our last invoices. I flew the Mk1 a few times, it was Fun, given a different owner/manager the Mk2 could have been very successful.

[@Nacionarg]

Just like many other comments, I couldn't avoid noticing a resemblance between the Speedtwin and the IA-58 Pucará, so here's an interesting fact: the recently reengined Pucará is the first twin PT6 aircraft certified as an aerobatic aircraft (formerly it was powered by Turbomeca Astazous).

[@johnmorris7815]

Ever heard of the Beagle Basset? A very short lived design that had very few civil sales but had some success with the RAF.

[@aircraftadventures-vids]

I sure have! Not quite as obscure as these ones I'd argue but still a good candidate for another video. When I used to work at FLL, there was a Beagle parked right outside our office, appeared to be in good shape.

[@johnmorris7815]

@@aircraftadventures-vids that sounds about right, there were one or two dotted about at various airfields, most had seen better days?

[@edcew8236]

The kit version of the Speedtwin was enormously over-priced. When an RV-6 kit was $30,000, the Speedtwin was asking $100,000. No wonder it never sold! It did have a unique feature to reduce aileron control forces, and it's not clear to me that conventional ailerons were inadequate.

[@aircraftadventures-vids]

Not only that, but that's not factoring in a pair of Lycomings, I presume. Plus all the associated mounting, plumbing, etc etc. There's been other kit twins that were attempted but nothing's really worked so far.

[@BodleyFludes]

Anyone else see the striking likeness of the fin/rudder profile of the Do 28 to the Mitsubish Ki-46? The little-known Reid & Sigrist Desford light twin is another attractive rare bird - now preserved for static display in Leicestershire.

[@jhaedtler]

I used to work with a guy that worked on the Speed Twin. The designer was very disabled but could really throw it around the sky.

[@DblIre]

For years, there were one or two DO-28 hulls at the Shawano Airport west of Green Bay WI. I think they were floatplanes. N774E may be one of them.

[@aircraftadventures-vids]

Yeah one of them was converted from floatplane to landplane, it's definitely one of them.

[@robbudden]

I always had a soft spot for the turboprop Meteor. Fitted with two Trent tp's it looked neat, although obviously the jet version was faster.

[@marcgini1443]

No mention of the cessna skymaster???

[@aircraftadventures-vids]

Pretty popular, was going for obscure. Plus, it's not 100% pusher.

[@joeobrien3541]

A condition of the certification of EVERY multi-engine aircraft is that is can be flown successfully after V1.

[@skydive1424]

Shame Fuji stopped building aircraft. The single engine ones are very robust, aerobatic and with great short field capabilities

[@aircraftadventures-vids]

I loved that LM-1 where they took a Mentor, converted to a 4-seater and grafted that huge jeep-looking roof on top.

[@ch64621]

The speed twin would have made a great training aircraft

[@aircraftadventures-vids]

That was the idea. My guess is over abundance of existing used twins precluded its need.

[@Flies2FLL]

The Rockwell-Fuji Commander is unique in that it involves Subaru. Yes, Subaru, the Japanese car company. At the time Subaru was a brand name and Fuji Heavy industries was the company. Fuji itself was a conglomerate created after the end of WWII by the Japanese government, which grouped together seven companies to produce Fuji, which got its name from the Fuji Rabbit scooter that was very popular. And one of the other of the seven companies was Nakajima, one of the pre-eminent aircraft manufacturers during WWII! Which means that basically....Every Subaru is actually a Nakajima. The word "Subaru" in Japanese refers to the Pleiades star cluster, which has seven stars, with six visible and one invisible most of the time. This is why the Subaru badge has six stars to this day. They finally got some common sense a few years ago and changed "Fuji Heavy Industries" into "Subaru". And they also had the common sense to stay the hell away from aviation!

El Speedtwin se parece mucho a uno de los primeros bocetos del IA58 Pucará, excepto por el tren triciclo y los turboprop.

Verdad!

[@larryweitzman5163]

Yeah, 4 obscure birds and the Rockwell 700. You left off the best small twin ever built, the Wing Derringer. Most are still flying. It was bueatiful and performed better. It should of had Lyc 360s instead of 320s. I saw a nice one at my old airport PVF. It would be terrific to see it back in production with the slightly larger Lycomings.

[@aircraftadventures-vids]

Too many to fit into one video. The Derringer is on my list for another twin engine series for sure.

[@larryweitzman5163]

@@aircraftadventures-vids Yes in airplanes, funny looking designs don't fair well. Both the Hansa jet with forward swept wings and the Hondajet OTW engine placement didn't and are selling all that well. For the Derringer at least it looked good. With 180 hp engines, it would have faired better as a personal rocketship. I met George Wing in Torrance back in the 60's at Torrance. John Thorp helped Wing with the design.

[@aircraftadventures-vids]

I can see the Thorp linneage for sure. I know less than nothing about the Derringer, but perhaps it didn't sell well as it only sat 2? Perhaps if it was a 4-seater it would have fared better against the twin comanche, for example. @@larryweitzman5163

[@MrLM002]

1.) Rarely do piston twins have engine "redundancy", instead you twice the likelihood of engine failure, and in all but the push pull designs your aircraft handling is much more dangerous in a traditional twin with one working engine than a single engine airplane with engine failure, the only saving grace being the possibility that you can get to the nearest safe place to land with your one working engine in said twin. 2.) The Do-28 B1 and the Do-28 Skyservant do not have even decent single engine performance. Both are STOL designs and STOL aircraft are almost always pretty draggy, most twins however are built for speed so they tend to be the opposite of STOL. At sea level on a not hot day you can probably climb a bit on one engine in a Do-28, though the turboprop Skyservant conversions probably preform a lot better. Also Helio made a Twin courier, none have survived to my knowledge. 3.) The Do-28 does not have more cockpit space than the Do-27, the Skyservant does though. The Do-27 and Do-28 definitely do not have spacious cockpits, the big windows help visibility but 6ft male barely fits in them, they were built by malnourished post war Germans for malnourished post war Germans.
