|Thread: Medium vs Hard Balsa|
Balsa is a very variable material even through individual sheets, I once cut a 4 inch by 1/4 sheet into four equal size pieces. There was nearly 10 gms difference between the lightest and heaviest piece!
If you want to be OCD, and why not? But a set of 'drug dealers scales'off ebay so you can weigh each part, Over the top? Not really build a pair off wings without paying attention to the weight of each component can mean one panel weighing much more than the other, this will have a much more significant effect on the models performance than a slightly miss selected piece for a spar.
|Thread: Which engine ?|
I have a DB Piper Cub. I fitted an OS 61 FS, pre surpass, and it's too powerful, unless you think a 60 degree angle of climb at full throttle is scale like. I agree with John Stones that even with careful throttle use it isn't pleasant to fly. I reckon a motor in the 48 to 52 range would be best. Also that vintage of OS four stroke wasn't that reliable on low throttle with the motor fitted inverted.
In simple terms for a canard which has a fore plane with elevators. The elevators move in the opposite sense to conventional elevators at the rear of an aircraft. So with the elevator moving downward the aircraft pitches up and with up moving elevator the aircraft pitches downwards. With an all moving fore plane with the leading edge moving higher than the trailing edge, i.e more positive angle of attack the aircraft climbs and vice versa when the trailing edge moves higher relative to the leading edge, reduced angle of attack.
Note however you will need to ave the fore plane at about 5 degrees of positive incidence to get stable flight.
|Thread: Do I need a new charger|
Due to restrictions imposed by carriers Lipos tend to be dispatched at between 20-30% of full charge. Many will have a note with them advising the purchaser to charge to storage level at least as soon as possible. Storage voltage about 3.6-3.8 v per cell. A fully charged new lipo should show 4.2 volts per cell. so 3 cell is 12.6 v. Hope that helps.
|Thread: A new caption competition - winner declared!|
Another six feet to the right and I would have through the gate.
|Thread: The Gov't, CAA, BMFA & UAV legislation thread|
Why not make the numbers a feature of the model? Letters as large as possible across the top of the wing, preferably large enough to be read by satellite or a passing survellence drone. That will fox some jobsworth when checking up on your registration.
|Thread: BMFA numbers. Is this true, or a gross exaggeration?|
The demographic drift is nothing new. I joined the SMAE (BMFA) in 1965 aged 16. One of the items I received when I joined was the current copy of the SMAE newsletter. One of the prominent articles was one bemoaning the lack of young people joining the hobby. OK the drift is much more serious now, but it's not new.
|Thread: Covering a sheeted surface in tissue and dope.|
I agree with Andrews post (post 2). However bearing n mind that you used 1/32 balsa and presumably joined 3-4 sheets edge to edge using shrinking dope could lead to problems. I would be inclined to use either banana oil or a non-shrinking dope for attaching the tissue and subsequent coating of the fuselage. Again all well thinned at least 50/50 or even thinner and use more coats as a consequence.
|Thread: P&P charges from the USA|
Postage from the USA to the UK using US mail is expensive. I wanted an IC for my Ace TX earlier this year.The IC cost about $10. Post to the UK $30. Post within the lower 49 states $7. I have a friend who has a property in Florida. Guess which shipping option I took?
|Thread: One handed operation|
Single stick Tx's were/are very popular in the USA, all of the US manufacturers and the major Japanese manufacturers offered a single stick,(cuddle box) TX. These occasionally come up on ebay. Most will be 54 or 72mhz systems. However conversion to 2.4Ghz is not the end of the world. Again Mike Ridley is your friend. Occasionally on ebay more modern modular radios with single sticks from either Futaba or JR are offered. However be aware these tend to command premium prices. These of course offer an easy conversion route using an appropriate 2.4Ghz module replacing the original module.
|Thread: Club Mower.|
I'm not surprised members are moaning if you need an Allen Scythe to cut the strip. Its a piece of agricultural/ horticultural history designed to cut tall grass for haymaking etc. If I remember correctly it still leaves a stubble about a couple of inches long. Hardly the bowling green that most people wan to fly from, although dancing might be a possibility.
|Thread: Steel ruler|
Simplest way to check the straightness of a rule or straightedge is to place it on a flat surface, a piece of white contiboard is ideal and using a sharp pencil draw a line along the edge(s).Then flip the rule/straightedge over and align the same edge with the pencil line at the ends of the rule/straightedge. Now draw a second line. It should coincide exactly with the first line, if not it's not straight.
|Thread: Car indicators|
I suspect that there is several levels of indicator non use. The prevalent one around where I do most of my driving is not to indicate left, particularly annoying at roundabouts where you are waiting to emerge this trick often causes a hold up. The second tier is to indicate after the front wheels have already indicated a change of direction and the manoeuvre is under way. The third tier is to ignore the signals of others driver indicating left to change lanes driver in nearside lane in blind spot decides to ignore it and scrape along the other cars side. The final and this is almost unique to BMW drivers is to approach a motorway junction. and to squeeze into the often quite small gap between two vehicles and onto the slip road totally ignoring the half mile empty space after the second car which would have made the manoeuvre much less risky.
|Thread: Wings and Wheels 2019|
I went to W&W on Saturday, it was quite warm! The wind being a from the crowd cross wind clearly made display flying tricky, especially for the smaller lighter models which once airborne would tend to drift away from the crowd line. I suspect that there isn't enough space to have two flight lines but with the present single flight line models are climbing turning away long before they reach the end of the crowd line. The relatively short crowd line was a positive plus for Sandown Park shows. The Weston Park crowd line is a bit shorter than W&W and that helps with the appearance of the flying displays. Also at Weston the displays are being flown through a 'canyon' of trees which places a back ground close to the spectators, not a feature of North Weald airfield. The trade stands at both shows are strung out on a long single line. I wonder whether arranging the trade stands in two probably shorter rows facing each other making it feel busier more 'market like feel would help and perhaps placing the Bring and Buy in a more central location might help.
|Thread: Interesting reply from email to Richard Moriarty, CAA|
Just switched on my cynical mode after I read this.
'The drone registration scheme is a top priority for the Government.' That would account for our failure to leave the EU on the 29th March, too busy dreaming up a drone registration system AND
' Any alternative approach for model flyers must be achieved without imposing undue burden on the state and the taxpayer, whilst also being efficient and enforceable, without compromising the integrity of the policy.'
So HS2 and other vanity projects aren't going to impose an undue burden on the state and taxpayer then?
|Thread: Suggestions for vintage model|
How about a Vic Smeed Mamselle? Belair do a 52 inch version. I have a Mamselle at that size lovely.
|Thread: Nostalgia trip - Reading Models "Red Admiral"|
Reading Model Supplies ceased trading in the 1980's following the untimely death of Stan Birch the the owner. The business carried on for a few months until Stan's widow closed the business down. Gerry Jackman went on to found Thatcham small Turbines until his untimely death a few weeks short of his 65th birthday. I was a regular customer from the late 60's until the business closed down. The Chatham Street shop under the carpark has long been demolished replaced by a block of flats. I don't think RMS ever produced kits.
|Thread: Successfully changing the AA batteries for the Lithium Ion pack in the spectrum DX6G2!!|
I bought a genuine lipo pack for my DX6 gen 1.Johnny B I feel your pain!
Now the bad news. I charged my DX6 with my DX8 charger, it's multi chemistry so quite safe. For various reasons the Tx didn't get used for a few weeks. Went to use it Tx battery was flat. Recharged, Tx left for a week or two Battery flat. It seems the little regulator inside the battery box causes the battery to self discharge! See if yours does the same.
|Thread: CAA registration consulation|
What is this "cheap off-the-shelf" U-Space/UTM registration system you refer to?
Do you really think that the BMFA should be running a database which will be connected to air traffic control, will be linked to the equivalent systems in other countries and will be accessed by the police?
With reference to the quote from Steve J's post. It is clear that recreational drone and model flyers are being expected to fund an all singing all dancing registration system which will be linked to everyone else's all singing all dancing Uspace UTM system. We will not benefit one jot and therefore we should not be paying. Clearly it would at the moment be very difficult to persuade potential commercial drone operators to foot the bill so the cost should be borne by the government.
Well I've written to Moriaty at the CAA, Baroness Vere, My local MP Alok Sharma, and just completed an email to Chris Grayling. Results so far CAA a stony silence, Baroness Vere an acknowledgement email, Alok Sharma an acknowledgement email and just arrived a letter, which looks like a standard reply, from Chris Grayling nothing yet.
However if we all do the same at least their in boxes will be super full.
