Title: New Bostonian Comp at the BMFA Indoor Scale Nats
Post by: Yak 52 on November 27, 2012, 07:59:12 PM
I've been given some info to post here on the new Bostonian competition to be held in the small hall at the BMFA Indoor Scale Nationals at Nottingham Uni on 21st April 2013.

The competition will be run to  'Impington rules' (14g minimum) and use the same score sheet. The rules can be seen here: http://www.ivcmac.co.uk/ivc02_events/ivc_events.html (http://www.ivcmac.co.uk/ivc02_events/ivc_events.html) Any number of flights can be made, which must be Rise off Ground. The total of your best three flights will decide the winner.

Apparently there were only 4 entries at October's Impington so spread the word!

If you have a satnav the postcode for Nottingham University Sports Centre is NG7 2RJ.

Yak,

Was it yourself organising on the day? Just a note to say thanks it was a nice added extra to the day.

Cheers
Ian.

Hi Ian,

No, it was run by Gordon Hannah who (I believe) also runs the Impington comp.

I entered my Cub for a half-hearted effort and got third place from a 38, 38 and a random 58 second flight that sadly ended up clobbering one of the RC flyers right in the head. I have a feeling there may have only been 3 entries (?) so it's wide open.

Jon

I had a word with Gordon on Sunday because I felt guilty not supporting the Bostonian comp as I intended ... I thought that he said that there were about 8 entrants?

Oh that's good then, I just assumed there were less because I didn't expect to be third.

Gordon found my time sheet. 3 flights of 8 seconds each I think I can claim last place with some confidence lol. I like bostonians though and hope to build something more competitive soon.

That's a good start - 8 seconds is roughly a circuit in the small hall?

What design were you flying?

I'd come along to trim and test some ministick designs I'm working on for class projects.  My dad loaned me his old General asked me to give it a few turns. It's seen better days. I'm playing around with some designs but I felt that the bostonians for boston thread is very important so as soon asI get time, after ofsted :) my first next build is a bostonian.

Cheers

Ian

I can confirm that there were 8 entries in Bostonian at the Nats. Six posted times, 2 didn't fly. The best time (3 flights) was 3.15 by Gordon Hannah (Sorta Senator), second was Nick Peppiatt (Sorta Korda) with 3.13 and third was Jonathan Whitmore (Cub) with 2.14. george Kandylakis was awarded a special prize for entering a true scale model (Belanca) that fit the Bostonian Rules.

I must admit that we expected more entrants, but we'll run the comp again next year before we make any decisions as to its future, so GET BUILDING - you can always try them out at Impington, and you can see the times you have to beat........

Thanks Andy. The small hall seems to me to be a similar size to Impington, with a slightly higher ceiling if anything. So trimming before the day should be relatively easy. It's cool to have the balcony too  :)

I must enter next year .... I've done a lot of Bostonian flying there, though mainly in the large hall on 'club' nights.
For some reason the number of fun flyers in the small hall has decreased in recent years?
Unfortunately I do know of several that have passed away or are now unable to fly .... I hope that this is not the case in general?

I think I will have a proper try next year too... I hope to have a better 'ultimate' design done by then.

I've been thinking about trying Bostonian.......suggest we pool resources Jonathan, and put Peterborough on the map at Impington in October ;)

I just fired up the CAD system and have one half drawn - will have a shot at getting it in the air after I've done the big Tailwind..  and the indoor glider project..

I had a review of my current projects recently and discovered that I have some 16 part built models in the workshop the oldest being an APS Fokker E-IV started during my time as a student at Brawdy in 1974, a further 10 requiring final trimming and 4 waiting restoration/repair. On top of that the wish-list contains 17 that I 'must' build including 11 scale all with adequate documentation, and that doesn't include the Bostonian....yet.

So many models and so little time........

Only 16 Andy?!  ;D You're not trying hard enough!

I've been working on the next iteration, done all the techy bits (new low Re airfoil designed in x-foil) and just have to draw it. Will you be designing one then Andy?


Title: Re: New Bostonian Comp at the BMFA Indoor Scale Nats

Yep - my thoughts are tending towards a rectangular wing with tip dihedral - the shape works well for the Lacey and I don't believe shaped wing tips make much difference at the size and weight of model we are looking at. It'll have my favourite airfoil - Gottingen 795 - with a couple of turbulator spars - I'm not worried about warps giving more dihedral - and a Peck grey plastic prop. The tailplane will be a non-lifting rectangle and the fin will have a swept leading edge. The fuselage will be pretty conventional with an upright config to contain the box. Wings will be banded on initially to get the correct C of G.

The config is very similar to a Peanut Duration machine I designed and built in the 1980s for a RAFMAA comp - it came second.

...don't believe shaped wing tips make much difference at the size and weight of model we are looking at.

I quite agree. Goe 795 is heading in the right direction, airfoil-wise. I'll send you some 'classified' stuff. I'd post it here but you never know who's listening  8)

Gottingen 795 mmm... as you say you never know who's listening..  and this is as far as I've got with mine this morning.. but really should be cutting rather large wing ribs...

Laurence, it's the outdoor season. How's the Tailwind coming along?


Title: Re: New Bostonian Comp at the BMFA Indoor Scale Nats
Post by: Laurence Marks on April 27, 2013, 09:48:55 AM
Should be doing the wings now Bill - in fact I'll stop typing and go and cut some ribs...

Wings will be banded on initially to get the correct C of G.

In that case you can humour me and build a few wings with different airfoils  ;D

Let's just hope they've degaussed the walls at Impington...  ::)

I'm looking forward to a 'SortaLacey' then Andy!  :)

It's surprising how little you have to deviate from the real thing sometimes to fit the Bostonian rules .... my 'OoLaLa' still looks like a Renard.

Still got my latest 'under wraps'! ... maybe this October at Impington?
Having said that, there is a perfectly good model already in the Mike Stuart SortaSenator .... Gordon won with it at the weekend, he and myself have won with it at Impington.
It is mainly about hitting the weight and trim for Bostonians .... and not getting it trodden on or wiped out of the sky at Impington!
