Here are a few pics. Its a modernized and downsized version of an EU1A which I think is a beautiful old school pattern ship. It retains the unique wing planform and adds some modern touches as a plug in wing (for fuse space) and a hatch for simplicity for an electric version (for battery changes).. It would be a .45 size glow machine and I do have plans to eventually try a IC power plant - but the prototype is electric. Its been a bit of a rabbit hole project. Started as an attempt to use 3D printing to make the plug for the mold - Which actually worked very well. It stalled a bit when I decided to implement a plug in wing as the work around figuring this out was troublesome as I fell into the "overthinking" and "overbuilding" trap. I really like the looks of this build and judging from the response of other "Classic Pattern" guys it seems to have hit a sweet spot.. Even the original designer of the EU1 has chimed in with his approval. https://cimg0.ibsrv.net/gimg/www.rcu...f112cbb322.jpg https://cimg2.ibsrv.net/gimg/www.rcu...6aa001417d.jpg https://cimg3.ibsrv.net/gimg/www.rcu...a70915b516.jpg https://cimg4.ibsrv.net/gimg/www.rcu...139a2bf465.jpg https://cimg5.ibsrv.net/gimg/www.rcu...de3054f581.jpg https://cimg7.ibsrv.net/gimg/www.rcu...ebf1de61df.jpg https://cimg8.ibsrv.net/gimg/www.rcu...593f7486af.jpg

Nice plane to replicate and some awesome work on your part, Chris. Well beyond anything I would attempt.
The EU1a came out somewhere in the mid 70's or thereabouts. Is it legal for SPA? |
Well its on the bad word list on other sites... nothing bad about it... it's all about what you like / personal preference... I just don't like the way that site is managed is all... no different than some forum's and their rules and regulations... it's all about self management... only post what you want the world to know about you... :)

So I promised some pics of the Fuelie Boxer's new home for testing - Here it is - You might recognize it as a bit of a recycle as it was the plane I was originally working on for the first ST 25cc conversion. Sizing up the plane and the space for gear I thought this might be a good candidate for testing the boxer. The mounting holes are still retained for the ST so I can make that switch later if needed. Lots of wing and a simple planform - Much like an Ugly Stick but a bit shorter tail moment and a few other tweaks.
Almost real to start covering - Just want to sort out a bit of plumbing and waiting for a few parts.. This one will get both the solenoid carb and the air pump setup... https://cimg7.ibsrv.net/gimg/www.rcu...09d55dcabc.jpg https://cimg9.ibsrv.net/gimg/www.rcu...557ef9109c.jpg https://cimg0.ibsrv.net/gimg/www.rcu...854ad8f293.jpg |
Looks like a sturdy build, Chris. With the removable high wing design and front hatch you won't have accessibility issues for sure. :)
|
I thought that was the candidate for the boxer... I saw it strategically cropped out in the background... should perform rather well with that wingspan... at first I thought it was something more inline with Bert's big tundra tug, but that ugly lookalike should be pretty agile. ;)
|
I have always had a "STIK" like plane in the hangar as I like how they fly - The thick wing lets you get away with stuff that a more efficient wing won't. Will give the boxer a bit of a workout too pulling it through the air. Despite the fact it looks "chunky" I'm surprised how light it feels for its size. We will see if it holds true to final assembly. Although plastic film is not my favorite finish - this one will get it to keep it as light as possible. Tons of room and access for "experimentation"
|
The wing is reminiscent of a Senior Telemaster, looks to be flat bottomed but hard to tell from the pics. I have plans for a Das Ugly Stik, ribs show to be fully symmetrical on that one.
|
Some later versions of the stik (midwest ?) had this flattened symmetrical foil I think - only a sliver is trimmed off the bottom to make building easier - Could have left this fully symmetrical as I made a nice wing jig and used it for the first time on this one.
|
I think this is the same model as Bert's big lift ???... Not too bad price wise.

https://www.legendhobby.com/product/...-35cc-sea209n/ The original BigLift was quite a build, because back in the early '70's (largest common availlable engines being .60 baffle piston types) it had to be light for its size so there was a lot of girders and strengtheners and doublers and such. But that maxi Lift sure looks like it is heavily inspired by it. Given my experience with Seagull, I think it will be a pretty decent piece of kit. |
Yes, it looks very similar... l've always liked the look of yours, and it performs very well on the gassified ASP boxer... this one's spec'ed for a 20-35cc, so I could put the GF40 in it, not that I need another slow flying high wing, but its a neat looking airframe... I'll have to try and find a way to sneak one past the Sargent Major. :)
|
Yep, Great Planes/Seagull planes are very well built ARFs, a step up from the standard Great Planes offerings imo. I have a couple of GP ARFs and violently hucked around a SG 30cc Edge 540 arf for a season, which I should have never sold.

By the looks of it it is a near direct copy visually (looks like the horizontal stab has been downsized a touch), and it comes with flaps and aillerons which the original did not have. For unknown reasons that was a rudder/elevator only design. I love mine, it is an extremely friendly flyer that handles quite a wide shift of CoG (relatively). And glider towing is a very satisfying activity... |
Ailerons / flaps could be easy added while building... yours seem to handle well on just rudder & elevator, specially when towing... Seagull must see an interest in this type model to make a production run... they have recently released a few unique models... Interest in their big savage bobber seems to be low though.
|
Mine has aillerons (albeit a bit on the small side, I need quite a bit of rudder coupling to get decent responsiveness). Most people back then added aillerons to begin with, because although the original design flew pretty well on rudder and elevator only, they were a handful to land properly in less than perfect condition, due to their fairly sluggish roll response on rudder only.
BigLifts are fairly popular in Europe, there are currently 4 or 5 in my club alone and I have seen at least 3 more come and go over the past 5 years. sometimes it looks like every club has a few. And strange enough, hardly anyone uses them for glidertowing, I am one of the few. Yet that was what they originally were intended for. more or less purpose designed for it in a time the suitable engines barely were availlable.... |

Nothing going on? Or am I missing out by not participating on facebook?

Not missing anything from Me Lonnie - just been crazy busy with other stuff and haven't had much shop time- In the mid winter Lull when spring seems so far away.. We do have a indoor fly this weekend that will spark some flying interest !!
I did get a set of digital FPV goggles for Christmas from my wonderful Wifey. Got it set up in a quad to try and its awesome - I can see the detail these old eyes need to Fly and Survive.. its going to go in a fixed wing machine next summer for some real FPV flying. |

I am in Indonesia right now, after 3 years of Covid restrictions finally able to visit my daughter and granddaughter again. Although I have a plane here (and of course it IS a "gasser" development here is basically non-existent: Flying for recreation only, no R&D going on. |
Thanks fellas. Not much going on here with models either.
|
In the upcoming week, I'll get my "camping-plane" flightready, that has been in storage here in Indonesia for 3 years.
So at least something to report, how an engine will either come or not come to life after 3 years with zero maintenance, care or usage. That would be this plane: https://www.modelbouwforum.nl/attach...52-jpg.266007/ https://www.modelbouwforum.nl/attach...10-jpg.266008/ And it's last actual run was just after installing the solenoid system, still without atmospheric correction (in the rather constant conditions over here, not really a necessity, not as mch as in the climate I call home): The stunning difference back then was that before installing the solenoid, the leanest it would go it still would leave a huge black wet oily stain on the pavement after a few minutes, and with the solenoid, that black stain was gone, a minor oily but clean patch instead, the engine by the ear running about as lean as it did before the solenoid. A bit better visible here: Mind you, this is old footage, next few days I hope to provide new. |
Bert - To what do you attribute the cleaner running with apparently the same mixture condition Pre and Post solenoid?
