Okay then, after some discussion it looks like Roman's idea for a cookup is up and away.
If everyone's happy then rules are as he suggested:


- Build a Bostonian or Bostonian-like plane
- Build from an existing plan or draw your own plan (Deviation in your own plan should be declared properly)
- Is 6 month for the deadline enough? (Sounds good to me)
- A picture with the finished plane in flight is needed to successfully finish the cookup

Shall we say the nominal deadline is 31st July then?

So far we have...
Roman
Pete F
Monique
Ates
Glue-finger
Korale

Post pics and progress updates as you go. Feel free to make more than one (for example if you build so fast that your first one's done before Roman even gets back from skiing.)

Ready...set...go!

Anyone else welcome to join at any point obviously.

To get the ball rolling (so to speak) here's a shot of my rough drawing for a model I'll call "Spitball".
It fits most of the Bostonian rules, except that at 4.5" the max wing chord is too great, but never mind.

Talking of rules, this is the definition of a Bostonian, according to the Clayton Indoor Flyers website:
Bostonian Rules - Clayton version
Maximum wingspan 16 inches
Maximum wing chord 3 inches
Maximum overall length 14 inches (thrust button to rear extremity)
Minimum weight 14 grams (without rubber)
Maximum prop diameter 6 inches
Capable to rise off ground At least two wheels
Fuselage must contain a ‘box’ space of 1.5 x 2.5 x 3.0 inches and must have a transparent front and side windows of at least 1 inch x 1 inch

Of course this cookup is for BostonianISH models as well as proper Bostonians and I realise that there are variations to the above rules anyway (eg. stating allowable props, biplane amendments, different clubs' regs etc.) but thought it might be good to have at least the gist of what a Bostonian is stated near the start of this cookup.

Count me in Pete,

Bostonians are perfect for our indoor flying meetings here in Newbury at a local school - you don't need much space to fly them and they seem to survive collisions with the walls well.  So, I'd quite like to build up a collection.

I drew up a Chrislea Super Ace Bostonian a couple of months ago but never got round to starting it.  Using the 3 inch wing chord, the required fuselage box fitted almost perfectly into a scale cabin area.  Of course the span is much reduced to get the 16" span - should look quite cute.

I don't know how many years that Sortasenator plan has been on my site, but late last year I finally built one.  I was very pleased to find out it flew off the board with just a touch of tail weight.  A bit of time taken to scrape the prop, and I should be able to get rid of the clay at the rear.  A loop of 3/32" rubber was enough to get it to the ceiling.

Great that you're in, Mike; we're really honoured to have you!
I like the sound of the Super Ace. The real one looks like a Bostonian already doesn't it?

That Super Ace sort of resembles the Observer, twin tail notwithstanding.

Having a hard time to choose between one of these three for the cook up -  

Boston Beancraft Banana
+ Appealingly unusual design
+ Appears to be an uncomplicated build
+ Said to fly well
- Possibly a bit difficult to trim

Windindicator
+ Looks like a sportier, vaguely militarized version of the BBB
+ Looks quite sturdy
- A more complex build than the BBB
- Likely appreciably heavier than the BBB
- Designer says it's a challenge to trim
+Probably still a reasonably okay flying sport ship, given the designer

Observer
+ Looks like a fairly enjoyable build
+ Okay appearance
+ Korale's flys pretty well
+ Probably the best choice as a rubber power training airframe

That didn't help.  Still can't decide.  If it comes to it, will just do elimination coin toss if I've not made up my mind by the time I finish the plane that's in the works just now.

Not at all difficult. I had the stabiliser shim as per the plan, some down thrust and a touch of left rudder and it flew beautifully in left - left circles. That was on a loop of 1/8th, after switching to a loop of 3/16th I only added a bit more down thrust for the extra power. And then it flew away. I've since built an almost twice sized version and will build another Bosto scale for this cookup.

Here is the Windindicator, so you can see the family resemblance.  The author says it needs to fly left as well, which seems natural as they look fairly similar.  Appears the relative incidences are different, but general structure is of a kind.  Since you say that trimming is not a problem with the BBB, that would clearly be the sensible choice between those two.

If things go really well, maybe build both, with the BBB as a prelude to the Wind'or.  It's not been announced yet if our local school gymn is going to open for indoor flying or not next month (closed for January), but if it does, the BBB has a better chance of being done in time.  I think I will try one.

Pete, thanks for starting it. I love your Spitball sketch Grin
Great to see that such an interest in this cookup. The announced planes are reat, cant wait to see them built.

Glue_finger, I know the problem with flipping a coin Roll Eyes To many great planes to choose from.

Still have some days skiing in front of me. Will flood my brain with fresh air, maybe it helps deciding what to build...
Hope that nobody has finished before I am back at the building board Cheesy

Happy building...

Looking forward to seeing this and the Spitball.  Hopefully they fly well, but even if not, just flying for the sport of it can be fun too, just enjoying the look of the plane in the air.  That would kind of be the idea in making that Windindicator I keep banging on about.

One of the planes I'm thinking of doing is a semi-scale version of the Davis 2A

There is a nice three view at the bottom of this page http://www.airbum.com/pireps/PirepDavisDA2.html

The 'Box' would be on its side in this case .

I like it! That's another one that already looks like a Bostonian before you even start!

This is what I'm working on. You can slide in the Bostonian box from the rear if need be Grin. The major deviation from the original will be the clipped wings. The rest is pretty close already.

Great stuff Ates ... that really lends itself to being a bostonian ... it'll be a real character build  Smiley

Just to continue something I mentioned on Pete's Chub thread .... I will add the 'FatCat' that I did a good while ago to my build list.
Hopefully one will be produced ... but I hope there is no objection to putting two on the list?

This seems to be gathering momentum nicely Smiley
I have been trying to concentrate more on scale stuff recently but I cant help but join in Smiley Although it maybe after the indoor scale Nats.

I will probably do something with my biplane idea...

That's nice too. How do the biplane wing size rules work again?
Can't help but notice that everyone apart from me is fitting their designs into a proper Bostonian mould. Today I had another go at getting an eliptical  Spit shaped wing to work with Bostonian dimensions, but it just turns out like a penguin go so I'm sticking with cheating on the chord.

I think an average chord of 3" would be 'in the spirit' for this cookup Pete.
I've never deliberately cheated, but I did notice that the chord of the tail plane was over 3" on my Chesty Jeep making it technically 'illegal' I suppose ... Didn't bother me because it was never going to perform competitively.
