From the Editor – August 2025

Greetings once more to one and all!  Firstly, I’m happy to report that I’m continuing to do well after my recent gall bladder surgery. Moreover, present indications are that the earlier removal of my stomach tumor appears to have been completely successful – my most recent quarterly check-up revealed no indications of any complications or carry-over other than the incisional hernia which unfortunately developed following that surgery. I’m now awaiting the return to work of my namesake surgeon Dr. Duncan from maternity leave. Hopefully she’ll get the incisional hernia sorted soon after she returns – it’s on her back-to-work to-do list.

After that issue is sorted, I should be pretty much back to normal for the first time in almost 2 years! I’m immeasurably grateful to all those wonderful people who have combined their efforts to provide me with such excellent medical care. I‘m also very grateful for the support and encouragement that I’ve received from so many of you, my valued readers.

Meanwhile, things are going from bad to worse down south in the USA, with many of the negative effects being felt around the world. The Mega-maggat is continuing to unleash a series of ill-considered decisions, hastily cobbled-up distractions and barely-literate pronouncements that seemingly have more to do with the mood in which he wakes up or the taste of his morning coffee than with any rational consideration of the issues or connection with reality. His various attempts to suppress and re-write US history would be laughable if they weren’t so damaging to his country’s intellectual integrity and standing. He’s too intellectually challenged himself to grasp the fact that true history writes itself – it just is what it is. The alternative is fantasy, which is what he’s promoting. His well-fed posturing while the children continue to starve and die in Gaza is beyond despicable. 

Apart from the drastic impact upon the perceived stature of the USA in the eyes of the world, the people most hurt are the citizens of his own country. Worse, although many Americans now recognize the reality of their country’s deteriorating situation, no-one with any power to oppose the Maggat is doing so in any meaningful way. Now that the US Supreme Court has begun issuing rulings based on political bias as opposed to purely legal consideration of issues, the citizens of America have lost one of their most significant levels of protection against the kinds of abuse to which they now appear to be subject at the whim of the MAGA-Monster. Why is everyone kotowing to him?? The guy’s a schoolyard bully, which by definition means that he’s an insecure coward – such people crumble instantly if opposed effectively.   

The sad situation in which America finds itself along with the rest of the world is due almost entirely to the increasingly irrational, illegal and unconstitutional actions of one seemingly deranged, intellectually-challenged, childishly vindictive and bog-ignorant megalomaniac with the demonstrated communication skills of an under-performing fourth-grader and the intellect of an insect. The words “truth”, “integrity,” “morality”, “respect” and “law” clearly have no meaning for him. Given his pre-election track record, how so many people came to express their opinion that this convicted felon was qualified to be President of the United States by voting for him in 2024 is quite beyond rational understanding - those who did so bear a heavy burden of responsibility for the result. A write-in vote for the family dog would have made more sense. The dog would have done far less harm …………..

An even more puzzling question which many people around the world are asking is why a supposedly educated and enlightened country of some 340 million people couldn’t come up with a better candidate to front the GOP. The answer to that one, of course, is that they could – they just didn’t.

Thankfully now turning to model engine-related news but still on a sombre note, I have to report that yet another leading member of the world-wide model engine community has left us. Dan Vincent (1939 – 2025), who was probably the world’s leading authority on 1.5 cc (0.099 cuin.) engines, succumbed to lung cancer on the morning of Sunday July 13th at the age of 85 years – he would have turned 86 on July 29th, 2025. My sincere condolences go out to his wife Dolores and to the rest of his family and friends.

Dan spent most of his working life working for the Sprint Corporation telecommunications company, designing and planning central offices throughout Florida, particularly in the Central Florida region. He was with Sprint for about 25 years and retired in 2002 at the age of 63.

Every man’s retirement is enriched by a hobby or two, and one of Dan’s passions was model engines. Like the late Jim Dunkin, Dan focused his research and collecting activities on engines in a specific displacement category regardless of their country of origin. In contrast to Jim’s focus on 2.5 cc (0.15 cuin.) engines, Dan’s area of interest was the 1.5 cc (.099 cuin.) displacement category. Over the years, Dan assembled an outstanding collection of engines in this category, along with a wealth of associated knowledge.

Although I never met Dan face to face, we corresponded regularly. I always found him ready and willing to share his knowledge freely and to provide images upon request – a number of his images appear as illustrations to various articles on this website. His unfailing assistance was always greatly appreciated, and he will be sorely missed ……………

Now on to far happier topics! Last month I reported that some additional information had been added to the previously-published article on the Majesco range from Parkstone in Dorset, England. Adding that information focused my attention on the fact that I had never tested my fine example of the early variant of the Majesco “22” diesel. Viewing such laziness on my part as inexcusable, I proceeded to have a great deal of fun by conducting a full test of the engine, also re-testing the later variant which had appeared previously in the original article. The full results of this comparative test have now been added to the article, along with a few additional details.

Conducting the test of early variant number 374 drew my attention to the close general similarity between that unit and the highly unusual unidentified 6.3 cc diesel which may be found in my Wotizit pages. The cylinder construction looks exactly like that of the prototype Majesco “22” diesel apart from being rotated 90 degrees to bring the induction components to the left side of the engine, presumably both to shorten it and to minimize any change in fuel head with the angle of the model’s climb. The side-mounted induction system and the very small tank are clear parallels with the design of the 0.74 cc Majesco Mite diesel. 

Otherwise, the general construction arrangement of the engine is identical to that of the Majesco 22, with its twin exhaust ports and single external bypass passage and transfer port opposite the intake. The quality of the engine’s construction is superb, and it starts and runs very well.

This has got me wondering if my unknown 6.3 cc diesel could be an experimental prototype by Majesco founder Jack Colyer, who is known to have constructed a number of one-off prototypes apart from his production models. We’ll probably never know the truth, but this tentative identification is the best suggestion that anyone’s come up with so far!  Any better suggestions?!?

In addition to the major change in the Majesco article, there have been very minor amendments to the earlier articles on the May motors, the Ueda range and the McCoy diesels. The first two are merely additions to the serial number sequences reported in those articles - there are no substantive changes in the information provided. The McCoy update provides sourcing information for the O-rings used in those engines. At the suggestion of my mate Maris Dislers, I've also reorganized my articles on the various Mills models somewhat, again without amending the information already summarized there. These updates have been made possible by readers who provided new information either direct or via the blog site - thanks, guys!! All of my articles remain works-in-progress all along, hence being subject to updates at any time - the accumulation of knowledge never stops (unless your initials are D.T.!!).

Readers may recall that in my June Editorial I mentioned that the mega-talented model engineer Don Sohn was retiring from active involvement with model engines due to encroaching health issues - he has some excuse for this, having reached the grand old age of 91 years and counting! I mentioned that Don's remaining engines and cars are now being offered for sale.

Having a deep personal respect for the quality of Don's work, I couldn't pass up this last chance to acquire another of his outstanding replicas to add to the numerous examples which I already own. I acquired his last replica of the mega-rare 1941 Black Panther tether car engine, as seen in the attached image. What a beautiful piece of work - craftsmanship at its absolute best!! The Black Panther is certainly an engine with a difference, and one with a tale to tell - it forms part of the Ira Hassad story which appears on this website. Other examples of Don's talents remain available at the time of writing - I encourage anyone with an interest in superbly-crafted replicas of classic model engines and/or cars to contact Don directly at donsengines@aol.com to see what he has left.  

OK, on to the new articles for this month! Given the continuing uncertainties which define the troubled times in which we live, I’m trying my best while I still can to make every edition count. Despite the many distractions which force themselves upon us, I’ve managed to assemble what I hope will be another interesting selection of articles for your reading pleasure.

The first new article for the month represents my attempt to rescue yet another of the largely forgotten model engine ranges from early post-WW2 Japan from the obscurity into which it has sunk. In previous articles, I’ve covered such obscure subjects as the Atsuta 19, the early KO models, the Boxer range, the STRONG engines, the TOP series and the ROC .049.  Time now to take a look at the Haru marque, which was one of a number of trade-names under which the designs of Mr. N. Haruyama were offered to the Japanese modelling public. Haruyama was a prolific if generally now-forgotten designer who was also responsible for the Sky Shark 49 and Sky Queen models. He may have been involved with the TOP engines in addition, although this possibility is presently unconfirmed. Regardless, he certainly designed and produced some interesting engines which are well worthy of documentation.

The second article sees us return to the USSR during the Iron Curtain era to take a look at one of the more widely-distributed consumer-grade engines produced in Ukraine, which was then part of the Soviet Union. We’ll share a look at the POLET 5.6 stunt engine which appeared in both glow-plug and diesel forms, being produced in considerable numbers from the mid 1960’s to the early 1980’s. Its primary intended application was club-level control-line stunt. The quality of manufacture displayed from one example to the next varied considerably, but a “good” one was a perfectly acceptable performer for stunt training applications, as my own tests have confirmed.

Finally, we return to one of our main stomping grounds in England to review the surprisingly numerous variants of the iconic 1 cc E.D. Mk. I Bee diesel, using which so many neophyte modellers (including myself) were introduced to power modelling. Although it was a truly excellent beginner and sport-flying powerplant, by the late 1950’s the Bee had acquired what I sincerely believe to be an undeserved reputation as a sub-standard performer. A substantial 1960 upgrade raised its performance to a level which matched that of the best 1 cc diesels of its day, but this upgrade was never publicized by E.D., hence failing to restore the engine’s reputation. All in all, it’s a fascinating story – hope you enjoy it!

That’s about it for this month, fellow enthusiasts. All being well and assuming that WW3 doesn’t engulf us and that my neighborhood remains free from the sound of tramping jackboots and gunfire, I hope to return in September with a few more reviews for your reading pleasure. In the meantime, I really appreciate all the expressions of support that I’ve continued to receive from so many of you!
