It was flying so stable, nice! Sorry about the damage - albeit minor...

She is absolutely beautiful. Are there any plans available, or is it totally designed and built by you Jon?

Well honestly, what a silly place to put a fire door. Great to see her flying though! Look forward to more.

Jon,
I think your BD5 is flying at a nice speed.
After a few 'nervous' trimming sessions, you'll will have it doing what you want.

I managed to get the BD5 all fixed up and took it outside to give it some space on friday. I had a couple of promising flights but there was a lot of windshear and she spiralled in busting the wing properly this time. The wing will need a total rebuild now  :sigh: |

Bad luck Jon. It sounds like it may have been a case of just more turbulence than it could handle. Spiral stability on this model would be an interestin exercise though. With a pusher prop adding more effective fin area perhaps more dihedral is required compared to a normal tractor layout. I'm sure you took all this into considration though.

Tell me about it - the saga continues... John, I actually wasn't too worried about spiral stability - before friday! It has quite a chunk of dihedral but it did seem twitchy in the gusts. It seemed ok on the (few) indoor flights, in fact at one point indoors I though it may have been 'under finned' ie lacking yaw stability As I suggested I've mostly forgotten whatever aerodynamic reasoning that was behind the original design (should build quicker  ) but I'm not so sure if I had thought of that. I was thinking that the pusher prop was stabilizing in yaw, but maybe forgetting the effect on the spiral mode... I remember that Tobgun's peanut was "surprising stable" for it's dihedral but of course it had less of a chunky fuselage. I think the wing was just too light anyway so I haven't had chance to get any consistency yet. Next one will be quite a bit tougher. I'm shelving it for the moment: I've drawn and started building a new Bostonian design with a proper airfoil (BE50). It's going to be called a Boston Beagle ('cause it has a long but square nose) and a less indecent tail moment arm (!). |

Jon, sad to hear that your Bostonian BD5 isn't anymore... Looking forward to #2 You are building a new Bostonian?! Popcorn is ready, you can just start to post the progress Best regards Roman |

Hi Roman, just the wing that needs a rebuild fortunately - the fuselage is fine. I'll do a thread on the new one soon - it's a 'characterless' bostonian though! Designed to win (hopefully) |

Jon, good to hear that the fuse is fine. Looking forward to the thread. Bostonians are never characterless Roman |

Or you could stay closer to the current topic/thread and build from the P-Nut plan I uploaded to the Plans Gallery today.  Dave |

Who can say? Will you be the first? Remember... this is an INDOOR Freeflight subject. Dave |

I am sure there are indoor RC planes (at least I am told there is such a thing)....but a BD5...who knows - maybe I will be the first!! Mike |

Thanks for the link Fred. Of course this one is only 75% BD5, but 100% Bostonian The BD5 repairs are working there way to the top of my to do list. I do intend to produce a finished plan but I would like to get it flying reasonably first... The peanut version looks good. Thanks Dave. Jon |

Clever use of the Lego as Build jig.
My kids had Lego Mats as well... quite large sheets actually,
It just occurred to me that A Lego Mat could be good to place/lock the Lego onto for accurate/semi permanent Jig fits.
OK.. Just added the links as reference. I thought it was on topic ??
Note that one can print those plans at.. Any.. scale one chooses to, even tiled.. as the freebie Acrobat X+ reader now allows it.
It builds into a ~40 gram model.. as is... sans avionics of course.

.... Finally got around to repairing the little rocket ship. I had to build a new port wing from scratch, but it's hard to tell other than the old one looks scruffier.
Hopefully I'll get this flying soon.
