    1. Is depron the same as foamboard? If not how do they differ?
    2. If I were to build a wing like a Keil Kraft Super 60's wing with a balsa leading and trailing edge and three spars, could I use depron for the wing ribs? For those unfamiliar with the Super 60 it is a three channel model with a 63" (1600mm) wingspan: https://www.benbucklevintage.com/index.php?main_page=product_info&cPath=1_4&products_id=11
    3. If I were to use depron wing ribs on such a model which glue should I use to stick it to the balsa? I assume that the same glue could be used for the balsa sheet of the leading edge and centre section.
    4. Could I use depron instead of balsa sheet for the leading edge and centre section sheeting?
    5. What problems could I anticipate if I were to cover a wing built with depron wing ribs with Oracover or Oratex?
    6. I plan to build a 1/4 scale Fokker triplane. Could I use depron for the wing ribs of of this model, if not why not?

    1. No. FB has a paper covering either side that can be as much as 2/3 of the total weight, but it is much stiffer and takes spray paint well. Most glues work on FB, including cyano, because it is a different foam.

    2. Yes.

    3. PVA, Aliphatic, Uhu Por, Foam 2 Foam, Epoxy, hot glue, silicon and probably foam safe cyano. Most cyano will melt depron.

    4. Yes. May want to glass or use Foam Armour.

    5. Heat melting or distortion? Although lots of advice on the web from people claimng they have successfully ironed onto foams of various types.

    6. Probably.

    Hi LHF I agree with what you say however if the Male part with the female pins is fitted to the fuselage they will stick out when not in use and be likely knocked . Either way its a compromise but far safer than handling an armed model.

    None if this us a new idea, so I suspect there is an off-the-shelf solution to fitting a plug securely in the plane without it getting in the way. 

     

    A powered up model is only as safe as the person handling it, no amount of switch combo or electrical doohickys will prevent an incident if the flyer is acting like a bag of mince and not paying attention to the fundamentals

    of safety. The likelihood of an electrical component going haywire on its own is vanishingly small. Yes it happens, but not as often as human error on the field happens.

    By a " Normal connector" I meant the same connector you use to connect the battery in the model. Beit a Dean's   or one of the XT  range , the XT60 being very popular for average club models.  The female part of the connector can be mounted in the fuselage side flush . The male part is then bridged to act as a shorting plug and when plugged in completes the circuit. After your flight the shorting plug can be quickly and safely removed making the model "safe" from starting unexpectedly.

    The male and female description is a bit of a misnomer on the XT connectors as the actual male and female contacts are fitted in the opposites outer caseing . To  clarify I'm describingu the outer plastic parts of the connector in the description .

    In that case, as this is being posed as a safety issue, the male connector/female pins (aka the battery side) should be affixed to the plane and the female connector/male pins should be the arming plug because it's the male connector that isolated the pins from each other in the connector, thus lowering the potential for an unwanted short.

     

    Although for what it's worth I regard any of these additional wiring systems as introducing a potential fail point, and good pit drills regarding tx discipline should be followed and are more important than any "solution" that involves fiddling around with extra bits.

    I don't think C8 was suggesting anything, just passing on information received and asking for comment.

    Isn't that the purpose of forums ?

    "I hear on the grapevine..." is hardly what I would call information. Hearsay, rumour or extrapolation would be a more accurate description. 

     

    Can we have a cited source before this thread devolves into another cycle of people getting their knickers in a twist? There have been enough speculative back-biting threads here already.

    Not half as dangerous as women in their cars roaming around in car parks on their phones.😡

    I'm curious; Are you making a joke, are you typing in haste or are you actually a misogynist?

  6. I use my dx6i on my laptop with a cheapo wired flight sim USB dongle from Amazon. There's thousands of them and I suspect they're all the same. Only 5 channels, but it does what I need and I didn't have to pay the insane money for the official Spektrum wireless dongle.

     

    I've used both Clearview and Realflight, and Realflight is excellent; it is by far the more flexible and accurate sim. I downloaded it from Steam and was very easy to set up. Some of the tutorials and challenges are actually quite good learning tools.

     

    I do find that stringing an HDMI cable from my laptop to the 50" TV and using that as a monitor gives a much better experience. It's far more immersive and gives a wider field of view as per real life; depth and height perception become less of an issue.

  7. Old fuel seems to work better as weed killer. I've tried it with both old and new high percentage nitro.

     

     Presumably it's something to do with the molecular change due to age and hygroscopic properties of the fuel that enables it to be more easily absorbed by the plant and travel down to the roots as opposed to sitting on the leaves and only burning the surface. 

  8. Not so long ago on this forum, and I'm not going to point fingers here - you know who you are, there were people calling for the mutilation and death of anybody involved in causing chaos at Gatwick (particularly the man wrongly arrested and despite there being no evidence this drone flying  actually happened).

     

    But now you're all condemning someone who basically had the same massive overreaction as you. I'm not saying waving a gun and making threats is a good thing at all, I'm pointing out that your entitled, self regarding, keyboard warrior hypocrisy is breath taking, and I am shocked but in no way surprised. 

  9. I don't know if this is just a vintage paperweight, but I'm sure a collector or technical wizz could make something of it. 

    There doesn't seem to be an aerial, and I have no idea of the functionality of the rest.

    The box is a Royal Mail medium package and weighs 2070 g.

    Make an offer if you're interested because otherwise it's going in the electronics recycling bin at the tip.

    Agreed. The only recommendation to clubs from the national associations is to state that in your Club rules so that those that join know it is there responsibility to comply. The BMFA has on numerous occasions emphasised that clubs do not need to be seen to actively enforce registration and the correct display of IDs, that is a job solely for the individual.

    So if the recommendation from the BMFA is for a club to state that it's a members responsibility to comply, BUT also says it's not the clubs role to enforce those rules... Which is it? If it's not the clubs place to enforce then the committee getting involved is essentially the club policing the rules.

     

    If the club won't let someone fly unless the number is on the plane, they have enforced the rules, but it's not their place to enforce the rules. Logically circular argument! OR do a group of individual members who happen to be in that club attempt to impose the rule, but it's also not their responsibility to do so?

     

    It's like a charter to enable the most pettifogging type of stick-your-nose-in club know-it-all!

     

    If this happened in my club, the person acting as rule police would probably be told to get bent in no short order!

     

    There's a club I used to be in that insists on having the serial on the outside of the plane (which they check in the pits) because the committee think it's the height of bad manners to pick up and look inside someone else's plane.

  11. It wouldn't surprise me if Amazon detected your use of the buy again link (something to do with IP addresses and cookies - I'm not a software engineer) and increased the price. 

     

    After all, how else is Bezos going to continue his space adventure billionaire penis measuring hobby?

    I take it you have a lot off experience of running a club and virtually loosing a field because of one sour apple ruining it for every one else.

    Having to  then  go to the farmer to  plead your case to keep your flying field

    Actually, I am the club chairman and we've had to tread very carefully more than once to retain permission to fly. So nerrrr! 😛

     

    I make the light hearted troll comment because that was one post (the first and maybe only post) by someone who is immediately taking an aggressive stance against what other people have said and has zero information on their profile. 

     

    In fact, now I think of it, "The Bush" is quite similar to "Neil Bushall..." probably a coincidence, but both profiles were created on the same day and you've only posted twice...

    It always amazes me how some people think they have an automatic right to join a club, especially when they are already members of another club.

    We vet prospective members. We have a joining fee and have a waiting list.

    We never turn away people who are new to our hobby and want to learn to fly.

    If a prospective member does not like how the club operates then they are not the sort members we would probably want and are welcome to go else where. 

    Do not feed the troll!

    One club i was considering joining told me the joining fee was there in part to cover the cost of their sky sports tv subscription so they could watch football in the clubhouse. I hate football and i am there to fly so why should i be paying for that? 

    Good grief! That is a blatant cash grab, even when the social aspect of a club is taken into account and other sports/events are available on Sky. I can't believe I actually agree with you on something!😁

     

    Although the thought of a big TV with simulator possibilities in the club house is an appealing one.

    I must be lucky - only 1 club I have been a member of had a joining fee. It was to cover the cost of having a key cut. This key was for the padlock on the gate leading to the single access point.

     

    Lots of valid reasons I guess......

    Or in the case of some of our members, getting yet another key cut when they lose theirs for the umpteenth time. I don't see the problem with joining fees; it shows if someone is serious about joining and helps cover club costs such as rent and equipment maintenance. We don't have membership cards, but I would welcome them as there is a public right of way around the field and the cost involved would be minor compared to the security it provides... As long as people don't lose them.

    Just brought the Eflite 1500mm F W 190. It comes with no swastika on the fin ( do not want to get into the rights and wrong about that. I understand both sides of the story about yes or no) 

    Anyone know where I can get some swastika decals the right size for this model 

     

    "do not want to get into the rights and wrong about that"

     

    ...and of course almost instantly people start talking about the rights, wrongs and reasons of that.

     

    Honestly, I despair of this forum at times.

     

    Ref. OP: Addlestone Model Centre have about a billion decals in assorted flavours. https://addlestone-models.co.uk/search?q=*becc

  17. I would love to know the correlation between people moaning about how pages of adverts have disappeared from the magazine (y'know, like the mag was in the good old days of rose tinted remembrance when you could spend hours gazing at the goodies) and those same people moaning about adverts appearing on a free to use website that they can very quickly scroll past.

    Watching the Silverstone grand prix yesterday on TV, several times I saw the shadow of what looked like a regular hobby-type quadcopter on and alongside the track.  Was that another idiot, or an 'official' TV drone?  Whatever, it doesn't sound right with cars going 200mph just below it.

    I didn't watch the gp, but if the shot was the same from lap to lap it was probably a camera rig called a libra.

    I have been involved in introducing the game to youngsters. .  Their enthusiasm to have a go remains the same, BUT in the past many were keen enough to take up the hobby. 

    Today's youngsters can't be bothered to invest the time to learn the skills required to fly a model.  They would rather keep their noses pointed at a mobile phone. 

    Maybe they (and posdibly their parents) simply don't want to engage with a cantankerous old man who is willing to write them all off so readily, like much of the over-indulged, blinkered boomer generation is wont to do.
