    BAMF boom repair

    I got a knife between the carbon skin and rohacell to separate the 2 about 30mm all round both sides of the wing then I got a sanding bar and slid it in under the carbon and sanded the rohacell about .03 of a mm all round both sides and then cut some strips of carbon tissue 60mm wide and slid them into the main wing half way and did3 layers all different ways then just supper glued it holding the carbon skin tight to the core so it bonded all 3 together and let it then dry ( cup of tea time ) then made a carbon spar to run down the back of the main spar about 70mm long by the depth of the wing and mafde it sharp each end and slid it in both ways down the back of the main spar then glued it to one side then cut the tissue sticking out till it would allow the 2 halfs of the wings to but up nice all round then I just supper glued it all and let set.then when dry I just got some wet and dry and sanded it smooth came out really good and I was well pleased so like I said yesterday me and simon had a couple of hours before the rain and we could not brake it so seems good and looks fairly tidy,if I wanted to be bothered a di of filler and a sand and some fresh paint you would be hard pressed to see the mend sods law the underside looks very good and neat so when flying you really cant see it at all and if flew same as before and did not seem to ned a c of g change so well pleased with it all

    (The weight shown on that front scale is with ballast) I had to extend the rear leg since my scales are not the same height. If it’s not level then measurements will not be correct.

    Well, its certainly wet and windy out there. The field at the back of the house has long grass in now which was great for soft landings. Elevator trim is somewhere closer to correct and with my biggest ballast stick (which is only 60g) I could just about hold position in the sky. No damage, everything held together. The CoG measuring device I was referring to was a cardboard version of a 3D printed thing someone posted on RCGroups. I can't find it right now, but basically if you have a stop to put the wing against and a known distance between the two points (200mm in my case) at which you measure the weight then you have: CoG (mm from leading edge) = 200(mm) * (Rear weight/Total weight)

    BMFA Buckminster. To much of a success?

    Hi Mike I get a similar buzz as I'm driving up the little hill to the main car park at Ivinghoe.......I get an even bigger buzz when I am joined in flight by Red Kites flying there Buckminster is a round trip of 240 miles for me, I don't compare the journey there and back as multiples of the BMFA annual subs I simply work out what else I could do with the cost of the eight gallons of petrol I'd have to spend, and how much that is as a percentage of my pension Oh, and BTW Mike DLG, there IS a good slope quite close to the National Centre, unfortunately it's not a patch on the Ivinghoe hills I too hope that other BMFA members visit the National Centre and enjoy its facilities, it's just far too far for me to travel for a day out, oh, and did I mention, too costly too?

    Multiplex Arriba

    Tissue covering: It's like Marmite, you either hate it or love it! I've always had an aversion to it, I guess because the skill or patience wasn't there when I was much younger. My dad's brother had a huge stash of the KeilKraft Flying Scale kit range, every time we visited he would give me a kit. I would build it fairly reasonably then hand it over to dad to cover it. We scratch built a 1/12 Lancaster in 1977, Nylon covered but with a bit too much dope, giving the 'starved horse' look on the fuselage. It's still in my loft. Just recently I decided to try and banish my covering demons and deliberately tackle tissue covering. I read loads of guides (everyone has their own way) and waded in to finish an Airsail Voltimer that I built in February. Unsure of the quality of tissue offered for sale today I found some NOS Star Span tissue. The trading status of the company supplying it is unclear, I would like some more, emails go unanswered. The Star Span shrinks very well with water only, if there are any persistent wrinkles they can be removed with a covering iron. The finished job came out quite well (for my standards!) and the only problem is the tissue is quite fragile as it's the lightest weight (9g sq/m) and is probably intended for smaller models. I bought some lightweight tissue at the Nationals a couple of years ago for a rainy day, it could be Modelspan, seems good quality anyway. It has a grain which I've placed spanwise on the Arriba tailplanes, one coat of 80/20 dope/thinners applied to the veneer and rubbed back, then dry tissue draped over the part and misted with a water spray borrowed from Mrs B. Same strength dope applied around the edges only then let the water do it's job of shrinking. Repeated on the other side. Just now I brushed the remainder of the surface with dope (missing the edges in case they come adrift), both sides at once to reduce risk of warps. I used the tailplane wires to hold it under a dead gel cell battery. Will rub that back (500 grit) then switch to Banana oil/Amyl acetate, as many coats as it takes to get a finish ready for primer.

    How does your split scale work?

    BMFA Buckminster. To much of a success?

    I agree with you 100% Mike. I think it is sad that some people cannot appreciate the fantastic facility we have with the National Centre. I wonder how many of those have even been there? I imagine that if it had a fantastic slope as well, there might be less discontent. But you can't please everyone all of the time.
  14. We have two major soaring events at the our BMFA National Centre this year - I'm going. I'll get a buzz driving down our entrance road to our buildings. I'll have indoor toilets and a kitchen where I can make a cuppa and I'll shelter in the hangar if it's bad weather. I'll meet with fellow model flyers - fly some gliders and have a good time - you can't do any of that via an online presence. I'll spend more than the BMFA sub just on fuel getting there and back. I don't think about how many annual subs the models and gear in the back of my car cost me. I'm just glad that our predecessors invented the BMFA and grateful for what is achieved for all model flyers.

    18mph gusting to 25mph might not be the best idea for the first flight at lunchtime. I have a spreadsheet of weights from my split scales so I can calculate CoG from the front/back weights. last recorded figures were: After repair its now: So obviously my scales are not that accurate because it seems to have moved the CoG back nearly 4mm without adding anything to the total weight!

    Stream NXT

    Well, after all my fuss, IT FLIES! Not an ideal morning as it's horrible out there, but I had to have a fly. First impressions, it feels a lot lighter and more agile than my Snipes were, really crisp on the sticks which I like. I have the UHM version and I haven't weighed it yet but it kinda feels like my Snipe would have if it were a bit lighter and a touch reward cg maybe? I think I'll be able to throw the NXT way higher, I'm sure I'm getting the height I was with the Snipe already and I wasn't even trying today due to the wind and not having thrown in a while, it just feels way more slippery on launch. Followed Mike S settings and with a 65mm cg it flew right out my hand, no trim needed and feels great to me so I'm not gonna change anything. Overall I think it feels and flies the way I kinda hoped so I'm super happy. I think I can stop chasing planes now as I can't see any new models being a massive improvement on the NXT, not that I'd notice anyway. Flew on the Spektrum IX12 too, love this radio, but I'm a bit worried the battery won't last a full contest day, so debating switching it over to the Taranis.

    Good job. How much weight did it put on?

    See attached. Four pieces of the uni-tape in total. Two full width wrapped around the sides and then two more half size strips on the sides. All cut at an angle with pinking shears to hopefully avoid any stress risers.

    BMFA Buckminster. To much of a success?

    Hi MikeF Thanks for reminding us all hat should happen but, in this instance, that of establishing a BMFA National Centre , I think you'll see that the main opposition to its cost came from forum members, not attendees at any meeting or AGM. The decision to go ahead with the National Centre, although we obviously clearly couldn't afford it, was no surprise to the respondents here, who said it could only be achieved by a large increase in subs......a comment proved subsequently to be correct Everywhere else in the hobby, particularly with regard to the closures of models shops, BMFA members were being shown that a physical presence, particularly in a purpose-built building, was an indulgence, and that everything necessary could be achieved by an online presence.......the buildings, such as model shops. were basically redundant, why therefore did this not apply to the BMFA itself? after all, we already had an office in Leicester........ BTW when I originally joined the BMFA I was told by many members that they had "only joined for the insurance" and had no interest whatsoever in the BMFA organisation itself........perhaps that could be a factor also?

    3m Electric Bird of Time

    Hi SP Sounds good to me too.......and I was prepared to accept the accepted offer price of £110.00 too.....if you re-read the posts on this BOT you'll see Regards Pete BARCS1702
  22. Sorry Tony, we seem to be drifting off your point but, for Steve. The BMFA is its members. The members send their delegates to the AGM or attend in person. The BMFA AGM takes 'a long hard look at its outgoings' and its income every year. The AGM decides the membership fees and approves the spending plans worked out by the members representatives at Council. So the members get what they corporately want and understand where the money comes from and goes too. There was a remarkably long discussion on fees at the last AGM with good points made for both increasing and reducing them. The overwhelming feeling from the floor was that we get very good value for money and there was a large majority in favour of the increase. Thanks Tony for your post rounding off the original discussion.

    1/4 Scale PIK 20

    Hi Adrian Possibly because I asked the same question, and I live in London and found two Hazel Groves on Google close to London that would have suited me nicely....... Regards Pete BARCS1702
  24. Hi all Interesting responses about the Sitar Special's looks....... At the time I remember it was considered a perfect example of single-minded determination to win at all costs........beauty just didn't come into it I remember the pic of the Austrian team's "rack" of identical models that was going the rounds, that seemed to exude single-minded determination achieved by typical Teutonic engineering thoroughness.....functional, not beautiful......... a bit like the Mercedes F1 team today.....it looked like It'd do exactly what it said on the tin! No, at the time, the Dassel/Sitar DARED you to try and fly it to its full capabilities.......not pretty, but looking like the winner it was........did you dare to fly what looked like a carbon copy of the World Speed Record holder?........very few actually could and/or did Regards Pete BARCS1702

    BMFA Buckminster. To much of a success?

    BMFA membership is expected to be 3000 down in '19/'20 compared to '18/'19. Their reaction to this was to increase fees. BMFA fees are now significantly higher than the other UK associations (they are almost twice FPVUK's). The BMFA needs to be taking a long hard look at it's outgoings (I would start with the magazine and all the committees that they spend money on) not looking for other things to spend money on. Steve
  26. Thank you all for your comments. I could have used the header "A victim of it's own success" and I could have used "Revenue" instead of cash. The latter of which I wasn't insinuating anything I'm sure the money is used as needed. My point being I think we're at an important stage on the centre's development. I appreciate like anything else you can't please all of the people all of the time. I support the centre. It's convenient for me to use as it's only an hour away. I also defend it as members in my area, who have never used nor do I think they will use, view the BMFA quite negatively I have no idea why and suspect it may be historical. I only re kindled my flying 10 years ago having given it up for 20 years so I may have missed something. I still stand by my feelings re the weekend flyers' having access and no I don't have the ideal solution but I think it's important to consider as if we don't we risk, possibly, alienation by the very members we should be trying to attract who in turn would hopefully encourage others. I for one will continue to use the site until I can't. Cheers, Tony
  27. I thought it was time I updated this. Have a look at the attached - comments/corrections welcome. Not every contest needs all the detail I have given and many of the tasks can be delegated. We often use Oleg Golovidov's programme :- http://olgol.com/F3KScore/ Have a look at that too. Checklist for running a contest v11.pdf
