Making bits out of tin plate and brass tube, all sorts of wire bending and even simple things like the position of servos, use of bellcranks etc. Words fail me... That's exactly what makes it such a pleasure to build... Ah yes but you have muddled up objectivity a subjectivity. Objectively they are a faff to build, fragile, and out of date when compared to other kits. This may be be enjoyable from an subjective point of view, but i do not agree and believe there are objectively better models out there for the purposes of our OP. The OP originally asked about the DB and TN kits, and i raised the fokkerc kit as it was likely our OP had never heard of them. Given that BT kits are well known, and were not mentioned in the OP, and are more of a faff than the DB or TN offerings i didnt mention them as i assumed they had been considered and rejected. In short, i tried to understand what it was the OP was looking for, and make recommendations that were suited to his needs and not mine. I think this was more helpful than joining a thread 2 weeks in just to be pretentious and condescending What an unpleasant post. Unfortunately I don't have time to read every post here every day, so yes, I'm late to the party, as if that matters. As for being pretentious and condescending, I suggest you re-read your own post...

Posted by Jon - Laser Engines on 25/02/2020 14:32:04: Cuban, i am not a massive fan of the Brian Taylor models myself. To be clear, they fly very well and look fantastic but they are also difficult to build, very outdated in their design, and often too fragile for club use. That isnt to say they arent an option, just that they tend to be quite a faff to sort out. As for the TN spit, i agree. They end up very heavy unless special care is taken. Dave, i will see if i can dig it out later. If its too much hassle i wont bother but i will see how it all looks. Why is it 'Outdated'? It really isn't difficult to build at all for the modeller with the experience it is aimed at. And what's a 'club' model?

"CAA announce New drone trials !" Except it isn't new... This has been planned for years. BVLOS trials

There's no such thing as 'Disc Clean' on a Mac. In any case, I can't see what how cleaning up the directories would make any difference to the way Firefox behaves...

Went today (Sunday). Two gripes, stupid number of bodies standing around in front of the fence blocking the view, and secondly, by 1:00pm today, most of the pilots and their interesting models had departed, leaving us with endless 3D aerobatic displays.

",I have driven most means of transport available, from tanks to light aircraft, and there is one thing they have all had in common. Their controls were always linear. " Errr... Some new cars have non linear FlyByWire steering. Airbus airliners have non linear controls, as do most modern military aircraft...

"Lets hope someone had bought it and it will continue to produce." I thought the machinery had been scrapped...?

Steve But thats partly what it's for. Go and ask the CAA...

What worries me more than anything is the numbers of BMFA members who admit to binning the BMFA news as it comes through the door, evidently having failed to look for any urgent safety or technical notices. talk about reponsible flyers.

1) All of the buildings on Scampton are listed, so any developer will have to preserve them. 2) The A15 will have to be straightened back out by any buyer - it's in the covenants. 3) There isn't a bottomless pit of money to preserve every wartime airfield. 4) Scampton has been run down for years - Labour tried to close it 10 years ago...

Posted by Cuban8 on 24/07/2018 11:29:04: Quote from someone who knows a thing or two............. Air Chief Marshal Sir Michael Graydon, Chief of the Air Staff from 1992 to 1997, said: "Scampton is a very good base. It has an extremely long runway and is situated in a part of the country which is ideal in many ways. "I just hope that all of these consequences of closing Scampton are fully understood and appreciated. I'd like to know where they are going to put the Red Arrows." He won't know as much as you'd think, seeing as he retired 20 years ago... The world has moved on...

Anyone worked out the weight of an A4 sheet of 1mm brass...?? Would 0.5mm be more suitable?

They've gone into administration... **LINK**

Thing is... It's all kicking off on the drone Facebook groups... The drone brigade all now think that if they join the BMFA they are exempt from the Dronecode 400 foot rule. How has the associations defined 'Model Aircraft' and 'Drone'...?!

Posted by Ikura on 30/05/2018 16:36:51: Yes you are quite correct. The BBC news item has been replaced with another one - "Aberdeen sanitary product pilot to start across Scotland". Lol... Arguably more relevant and of a lot more interest to a lot more people...

Posted by Ikura on 30/05/2018 15:43:23: Posted by GONZO on 30/05/2018 14:38:04: I have no doubt that any costs will eventually be placed on us. Note that in the article it talks of subsequently MAKING all users of drone use a smart phone app.(sold as a safety feature to help you know about other traffic) which will no doubt be linked to a mandatory installation of some form of transponder/telemetry device. You will in effect be paying for and doing your own policing and providing any evidence for your prosecution if you should infringe the laws. That is all pure speculation, bordering on fantasy. It will never happen, especially the way you think it will. The CAA WILL want transpoders eventually, and yes, we will pay for them. They are here, now. **LINK**

Posted by Ikura on 30/05/2018 14:10:02: The article is no longer on the BBC website front page. So much for the big scoop. The BBC are just as sensationalist as the rest of the media. My take on it is that it's a poor news day so the BBC have to drag up old news and make someting up out of very little. Edited By Ikura on 30/05/2018 14:12:03 It's no longer on the BBC News website as other news has taken it's place. How long would you like it left there? A week? A Month?? The BBC haven't 'dragged up old news', they've reported on a new piece of legislation heading for Parliment. How hard is that to understand?

It's been shown around all the German shows over the last few weeks.

I was about to write a long piece about LiPo chemistry, but it appears from posts today I'd be wasting my time. I can't think of a commercial LiPo charger that will charge a LiPo if it's under 2.5V or thereabouts, and absolutely not from zero. This isn't something the charger designer forgot to incorporate, it's a safety feature, a safety feature most here seem to think it's fine to overide. It's there because over discharging the cells permanently changes the cells chemistry, and therefore, is a clue they shouldn't be recharged. Yes, I used the words 'utter lunacy'. Sorry if that's a bit strong, but nothing I've read here has changed my mind, inlcuding the gem above, "if the battery has a CE marker, it will be fine."     Edited By Guvnor on 12/05/2018 19:28:34

Posted by PatMc on 11/05/2018 22:30:17: I'm not taking any risks. I haven't expressed any opinion regarding whether the battery is safe or not. You're making claims of dire consequences but so far not giving any credible backing for the claims. In which case you're no more than expressing an opinion. Is this the opinion of an expert ? Do you have some expert knowledge of lithium cell chemistry & are you qualified to make the claims that you have ? I do have some knowledge of LiPo chemistry and charger design. Why do you think LiPo chargers refuse to charge LiPos who's V has dropped below a certain threshold, usually preset to 2.5V with a small load? Most commercial chargers use COTS chip sets, TI in particular. Clever ones WILL give a short gentle kick to try and revive a low V cell, but NOT from 0V. The charger chipset designers will assume that if the starting V is under 2.5V, the cell cannot and must not be charged... Have a read here: https://www.digikey.co.uk/en/articles/techzone/2016/sep/a-designer-guide-fast-lithium-ion-battery-charging From this link: deep discharge, like overcharging, can damage the cell.   Edited By Guvnor on 12/05/2018 00:16:03 Edited By Guvnor on 12/05/2018 00:17:24

If you're happy to take these risks with no understanding of what's going on between the plates then that's fine, go for it. You obviously know nothing about LiPo chemistry. Which part of "This is a dangerous situation which can ultimately cause a short circuit between the electrodes." is a mystery? As the battery was discharged to 0V, then forced back up, those lovely copper strands are right now shorting between the cathodes and anodes. Not a huge amount and they will instantly destroy themselves. But one day the battery will be knocked or pressed and it will short properly. Why take any risk whatsover with a damaged LiPo? Please, just bin it...
