67 and Hoping to get Back Into the Air
After years of procrastinating, I'm thinking about building a trainer.
I have everything as far as materials. The sirens call, was the new
https://www.ebay.com/itm/Coroplast-Control-Line-Engine-Mount-Man-Win-Trainer-etc-offset-18-degrees/224283092131?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649
After studying the plans and photos, I noticed somewhat of a discrepancy. It looks like the tail feathers in the photo
also have an offset not shown or mentioned on the plan.
I can't link the photo, so here's the site. The photo's on top.

Any thoughts?
My loving wife asked me if I had an engine for it. At least a hundred was my response.
Doh! Opening for a new mill, gone.

Bob!
That was the best Christmas present you could give me! So glad to hear you have made a step in the right direction.
I know nothing about the man-win trainer. It doesn’t have much going for it apart from looking somewhat robust.
Do you have anyone to fly with or are you planning on a bath mat stooge launch?

Re: 67 and Hoping to get Back Into the Air
Thoughts? You asked for them!
Having been designed here locally, I have flown both the original as well as the one you linked to, and in my opinion is the better of them. I have about 4 or 5 of them all over... So if I am reading your question correctly, you are talking about this:
WHat it is is not offset. That is simply the hinge. As the material is 4mm coroplast, what is done is you cut away the material from ONE side of the plane, thus allowing you a 'hinge'. I personally also cut out small sections on both sides just to make the 'hinge' looser. If left full length, it is very stiff. I will post a couple pictures in a minute. As well, that mount looks very nice, and is reasonably priced as well. But I personally just grab some scrap tin (K&S I believe) and bend two up quickly as when you do a figure 9, the engine may bend out of shape, but you grab it and simply bend it back, and fly again.
I use 3 #10 x 3/4" wood screws near the outboard wingtip. And as well, I do not use carbon rod. I simply push a bamboo barbecue skewer in so it is roughly in the middle and call it a day. After it is inserted, I just put a bit of glue in that particular 'flute' on the ends so it does not come out. But I have never had any problems, nor has any of my planes had any damage from doing it this way. I had let many people fly 2 of my planes and they are still as is when I made them. I hope this helps. If not, please feel free and I will do my best to help you out.

Re: 67 and Hoping to get Back Into the Air
Sorry I also forgot to mention I remove the complete section from the bottom as opposed to the top as shown on the plan. Personal preference and no adverse effects. I just pass a lighter over the inboard wingtip and on the leadout guide to prep it before gluing. And I use the cheap 5 minute epoxy for that.
Just go for it. You got this! This thing will help you fly again! It is no big performer, but does fly well.

Thank you, Ron. It'll be a solo act for sure. I just have to findCribbs74 wrote:Bob!

a place to fly. Probably some hidden, unused clearing, maybe a school or something.
There are a few possibilities on some of the campuses, where I work.
Merry Christmas to you and yours, Ron.

Re: 67 and Hoping to get Back Into the Air
The only reason I asked was because the model you selected has no gear. Kind of limits your launching methods. Lot’s of info on the bath mat method though. Pretty sure I know what the power plant will be

Thanks Chancey. Between you and Ron, I'm sure I can achieve some sort of success.NEW222 wrote:Sorry I also forgot to mention I remove the complete section from the bottom as opposed to the top as shown on the plan.

I'm not going to turn this into an epic build thread, but i'll keep you guys posted.

Yeah, Ron, It'll be the bath mat. I've imagined the first launch several times sinceCribbs74 wrote:The only reason I asked was because the model you selected has no gear.

the first time I saw Rusty's video. I also have access to 4' X 8' sheets of corflute, so the runway
thing might be an option.
Wheels be turnin'.
