So just to be clear, the invasion stripes are different coloured PLA?

Looks brilliant.

i mix printing with depron in my builds.

my aerobat has a 3d printed front section including battery box, motor mount and u/c mount with a depron outer skin.

The wellesley has some thin 3d printed formers to maximise internal space for cockpit detail.

Tony B

Mixed builds seem a popular way of making up for missing detail, how did you find the weight worked out with the printed formers?

I've got some catching up to do! Nice work everyone thumbs up.

V2, the Canadian Version?

Looks like it's addressed some of the issues of the original version (the one I have) so although I have been flying it for some years I don't think I can help.

Hi Colin,

Found where I'd seen something silimar before, using Microsoft 3D Builder (if you have Windows 10 then you have this).

I'd scanned a pencil drawing of a rib, then cleaned it up a bit and saved it as a jpg.

jpg to object 3d builder 1.jpg

I then imported it into 3D Builder and was presented with a solid block instead of of a rib. Note two settings in particular here, Method: Stamp and Inverse:Off

jpg to object 3d builder 2.jpg

Inverse seemed a logical enough change and worked, well sort of. Familiar?

Next then I changed the Method, trying all those available until I came to this one, called Contour. An interesting thing to notice here is that the hieght of the block is subsantially less. Begs the question of what if I set the Inverse:On?

Well here's the answer:

I apprecaite you are you using different software but perhaps there's a pointer there somewhere?

Colin, I've seen something like this before, different software but might help perhaps. I'll need to create and upload some images to explain, so I'll come back soon and do that, unless you have already sorted it.

Hi guys,

i also have the malyan M180 + Sd3. Just had to install a new mainboard. Has somebody succeeded in changing the steps /mm on the M180 side or do you all adjust this in Sd3?

Thx

Peter

Can't say that I've needed to look into steps/mm though as Tom says this is in the gpx file which you can edit if need be.

That look great Tony.

Robin, one solution I am looking into is mixing 3D printing with traditional building. Can't report much at the moment . Health problems have slowed down all of my activities, including progressing with 3D printing, hopefully that all going to improve now and I'llbe able to update when I've got some positive results.

I would very interested in how you go on with the fully skinned printing as that is another (delayed) project I am working on.

What filament have you used Itisme and why did you make that particular choice?

I see you used PLA for Kaydet, doe sthat apply to the others too? I'm very interested in trying appreciate the pros & cons of various materials availble.

Thread: Fusion 360 for modellers
18/02/2018 13:30:53

Good points Nev. Getting to grips with a cheaper model can be a valuable step towards getting what is wanted at a later date. That's another thing if a current printer satisfies what is wanted then future changes in the technology might not be too important.

Thread: Best Plane You Have Owned
18/02/2018 12:11:36

I can think of a good number of models I have that I enjoy flying immensely and would never want to be parted from but it was still an easy job to answer the question asked. Why? Well this model:

  • Is only my third ever model,
  • first flew in 2005,
  • has flown many, many hours since, year after year,
  • last flew it in autumn 2017 (will no doubt fly again soon),
  • only repair it has ever had has been to replace the undercarriage (see here),
  • although not true scale it looks the part,
  • requires full house control inputs for slow turns and to look right anyway,
  • which keeps flying it interesting,
  • has a reasonable amount of aerobatic ability,
  • engine (SC FS52) hardly ever misses a beat, sounds great and is a good match,
  • I just enjoy it so much,
  • fits in my car fully assembled (just),

so here it is:

A Flair Se5a?

Nope (Alex Whittaker take note!).

It's a Ripmax Se5a with a few extra bits added (rocker covers, exhaust pipes, leather cockpit surround, identification ribbons). Only down side is the shiny covering, though to be fair late and post was versions were polished.

Just love it.

Thread: Seagull P40 - weak bulkhead / poor design
17/02/2018 13:21:36

This sort of thing is limited to ARTF's is it?

Has no one has ever built a model themselves and only found out afterwards that it has weaknesses?

The P40 certainly shouldn't have come apart as it did and it's an issue worth raising but this thread is at risk of knocking all ARTF's generally and that just isn't a balanced discussion.

Hi Cliff

A clubmate had one of these, out of the box it was very tail heavy with a 3s 2200 in and needed a hefty piece of lead in the chin behind the grill. Flew horribly without it and superbly with it. Nice model

I experienced the same problem with one I maidened for a friend. Looks like it might be a feature to watch out for.

Snip.....I’m very impressed which how it works, the critical thing is the first layer, 1 thickness of A4 type paper used to set the bed height works for me.

Good luck with it.

Thread: Looking for a ARTF Trainer - non-foam
27/11/2017 15:59:38

IMHO by far the best trainer is the Irvine Tutor 40/Tutor 40 II. This one model can take from absolute beginner, through the A & B tests and beyond. A very close 2nd is the Seagull Boomerang. Both of these models have semi-symmetrical wing section accompanied by just the right amount of dihedral to make them straightforward to fly the basics yet reasonably capable of all the basic aerobatics. Models you can reliably go back to when training is completed and have loads of fun.

Behind these there are other very good trainers, the rest of the Seagull trainer range in particular (but see next paragraph), some of which have been mentioned, then the there's the WOT 4 and similar.

Then there's the good trainers. They are good but I would be less inclined to recommend because of their flat bottomed wing section, the Seagull Arising Star being one such example. They fly exceptionally well and very easily in fairly calm conditions but are more tricky in the wind and not so good with aerobatics as the aforementioned. Compare flying an Arising Star inverted with A Tutor 40 II, provided they are properly balanced the Arising Star will do it but the Tutor 40 will do so much better.

On the subject of balancing, I'll get on my usual hobby horse, don't balance a little on the nose heavy side, "a little" is about the same length as a piece of string and often results in a model that flies well but lands badly, for which the undercarriage usually gets the blame. The instructions provide you with a balance point that works, so work to that.

One final point, if you already have foam trainers then the likelihood is that you already have at least a little flying experience with very easy to fly models, so it might a good time to consider one with a semi-symmetrical wing section whether it's one I suggest or not.

Maybe in the UK the point is that the box lid is kept closed.

That box lid is only closed to the law abiding, and has never had any discernible impact on criminals - as I've already pointed out, a short look at the stats shows that (a) gun crime pre-WW1 when we had practically no real restraints on gun ownership was at lower levels than today (yes, allowing for the fact that our population was half today's), and (b) as gun laws have become ever more restrictive (i.e. continually bigger & tighter "box lids", so gun crime has simply grown in parallel. Gun laws and gun crime are not connected: criminals do not obey laws - that's why they're criminals. They certainly don't obey gun laws. Why would they?

rgds Tony

"Gun laws and gun crime are not connected: criminals do not obey laws - that's why they're criminals. They certainly don't obey gun laws. Why would they?"

Shot yourself in the foot with that one Tony! If there were no guns then no law would be required and there'd be no opportunity for criminials and others to misuse them (remember the opening post for example).

Furthermore your reasoning will not help anyone that has been injured or killed through the use of fireaerms whether lawfully held or not.

The self protection or protection of ones home is poor argument as it's just not possible for you to produce statistics that show a high enough percentage of home owners are at risk of being faced by criminals with firearms to justify that stance. What's shown in the bias of the arguments you put forward are that they are more political motivated than reasonable protection the average person.

A post above mentions people blowing their brains out with guns.

My brother in law is an undertaker in the Crewe, Cheshire area. Crewe is a major rail junction and people jumping in front of trains is a regular occurrence. According to my brother in law, cleaning up body parts from half a mile of track is not a pleasant experience.

Suicide with a gun would seem to make it much more simple for those that have to deal with the clean up.

Yes it's very unpleasant indeed but bullets can be quite messy too, as for shotguns Tom, you should see the mess they make at close quarters, bits all over the place. I was just about to describe it but thought I'd better not.

25/11/2017 14:37:46

It doesn't matter how high your horse is or on which side it's ridden, the purpose of a firearm is to kill, that does not apply to all the other analogies that have been made. That there are now also sporting uses for firearms is beside that point as the more firearms there are; the more suffering there is because of them.

I've had the opportunity to try a few firearms from time to time and been surprisingly good at it but I do not think that justifies any further interest in them on my part.

Thread: 2018 Mass Build - Voting Thread
23/11/2017 19:58:34

The Mass build is an excellent idea and I have taken part in the past. I would do so again but I have so many models and such a slow build rate that it's not practical to join in every time, as much as I would like to. I would certainly have preferences amongst the models mentioned but it wouldn't really be fair if I cast a vote with no intention of following it through.

Unless I'm mistaken, this forum isn't as active as it was in the days of the early mass builds so that may account for the low take-up rate to some extent.

Although MB build blogs here are the norm, I wonder if a timely build featured in the magazine would help?

I also wonder if returning to some of the original concepts would have any influence on the take-up, e.g. to donate to a charity, a build suitable for absolute beginners and a quick one at that?

Stearman PT-17 KaydetFinally finished and flown, it needed the motor assembly moved forward by 10mm to get it to balance properly. Surprisingly there’s were no nasty surprises for it maiden flight.

Fantastic !

Where did you get the build files? What filament did you use, how much does it weigh, got any video? Questions questions!

Could tell all in another thread if you want, I'm sure lots of us would like to know more.

LOL, I'm sure it will Tony.
