My lipos are in a cabinet (inside tins), I could use a box like this inside the base of the cabinet. That bit of heat could actually reduce your battery life ! Have a look at his presentation - page 18 or 19 on the attached link - it's a good authoritative read on all things LIPO translated from German **LINK**

Thanks Frank. I wonder if my needle is an old / problematic design as Jon's needle has 2 o-rings and this is what the last poster , Tom Doyle, some 10 years ago was getting at before I resurrected this thread see below. I guess they would have had to send out needles and o-rings even if the needle part was the same as they both lost their's in flight ... "Just come across this thread so my contribution is probably too late. I and two clubmates have all had similar problems with Irvine 53s i.e. undersize/loose fitting 'O' rings on idle mixture screw. I was the luckiest in that I noticed the idle screw on my 53 had almost unscrewed itself during pre-flight checks. My two clubmates weren't so lucky, their mixture scews dropped out in flight! All three engines suffered this problem after about half a dozen flights. Interestingly, Ripmax sent out new mixture screws immediately and without quibbling - we got the feeling we wern't the first to experience this particular problem and that Irvine may have had a quality issue.

Sorry here is the o-ring over-haul kit i was referring to above (second link) **LINK**

Jon that's a very kind offer. Just managed to retrieve my plane from storage the needle look like which is slightly different to the one shown in your pic **LINK** (better picture than the one I just managed to take). In the meantime, I managed to get my hands on an overhaul kit identical to this **LINK**. Can anybody please tell me which if any (given that the needle is a different design) of the small o rings I should fit and does it simply fit into the brass bit of the carb where the needle came came out of  (if it does there was no o-ring present when I removed the needle) ?

Tom D Roll on 10 years and I seem to have the same problem as above. First problem occurred in flight. Didn't have a new secondary screw to replace the one that fell out so put in a new carb. When going to tune it up I was struggling (it my first glow engine model) I thought the secondary screw moved too easy. Lo and behold asked a more experienced member within my club and he noticed it right away and commented on it. Which brought me here and to this thread. Obviously Ripmax aren't going to send out new secondary screws as Irvine is long gone and Ripmax don't appear to have any stock. Does anyone know how the new secondary screw differed to the faulty one or, even better, know a fix to the problem ? Plus has anybody got a parts diagram for an 1850 Jet Stream carb which they could please share ? Thanks C

Know you will all be out rushing to get these **LINK**

Have a look at the videos to see what the bigger batteries could do to a bat safe box. A bat safe box is only rated for 2 5000 mah 6s batteries - go over this, not hard, at your pearl - see from 3.13 mins  Edited By conrad taggart on 18/10/2019 23:20:24

I currently keep mine in 4 Bat Safe boxes **LINK** within Lipo sacks. and for charging using the set-up shown in the picture. The only difference being i have a parallel fused charged board within the Bat- Safe boxes to keep leads to a minimum and so i can charge a number of batteries at the same time. The charger also has a temperature gauge sensor, which fits in the box and cuts the charger off should the temperature inside exceed 50 degrees (can be set to what ever you want on the charger). However, given the number of batteries I have and how dangerous they can be - **LINK** - I am considering buying some ammo 50 cal ammo boxes, removing the seals and storing them outside in a steel type dustbin/ container where no harm can come to anything. This seems to be doable if the attached is valid **LINK** I will simply bring them in to charge, let them warm up a bit beforehand then place them in the Bat-Safe boxes and charge as before. Taggarc Ps I know they provoked the batteries to ignite in the videos and left them fully charged, but the video does show very well how destructive they can potentially be   Edited By conrad taggart on 18/10/2019 18:14:09

B&Q sell it - the clear one is the best - most versatile in terms of matching / not showing. They also do a brownish one

Posted by Dad_flyer on 06/10/2019 16:20:02: +1 for zippy from HKing. Very low internal resistance, even on 25C rating. Just need to get in when the right size are in UK stock. Also the web site gives £prices, but the bill comes in USD and your bank may charge, and may have a different exchange rate. Still one of the least expensive options. Brilliant batteries but by the way it is best to buy your stuff from the European warehouse - believe it or not postage is cheaper / free over £39 (?) and they have a better range of products than the UK . The Zop batteries even when new have 3 times the internal resistance of other brands ...

Looking forward to seeing the repairs and learning from it - the more detail the better. Thanks Conrad

Neil - check your inbox ...

Dale was it one like this **LINK** Plus when it got up tot temperature I take it they generally all got back to the same level - burning about .1 litre per hour. The above one states Fuel consumption: 0.1~0.24L but i can't find a range for the 5 KW model. What size space do you heat please and what made you change to a manual control? Thanks Conrad

Are any of these heaters better than the other and is the KW output any different when they are up and running ? Seen a few videos that suggest they may be different when they fire up but they default to the same rate once they get pass the warming up stage. Reason why I ask is that I can get an 8 kw one for good money but it would be overkill if that is its true output and I would have to turn it down / off all the time which i guess could be a bit of a problem in terms of its operating efficiency / longevity. Any insight into the above / potential problems greatly appreciated Conrad

How is everybody finding these now that we are nearly a year down the line and what was the best source ? Thinking of getting one before the really cold weather sets in. Thanks Conrad

Spent a lot of time researching chargers. This one has good reliability and is on special offer. It is a copy of a much more expensive I-charger and has the same software **LINK**. The 350 watt version isn't as good / reliable and doesn't have the same firmware - with IR measurement etc. Being a single charger it is less likely to fail or lead you to junking 2 instead of one. Plus you can add a dedicated power pack for a relatively small sum **LINK**. If you add a Bat Safe box and put a parallel charger in it you have a nice safe convenient unit looking like the attached **LINK**. The above charger can also have a simple £3.50 temperature sensor attached to it (also sold by Hobbyking) which will shut the charger down if the temperature in the Batt-safe box exceeds the set parameter (the default is 50 degrees).

Thought some of you might find the following interesting in light of the new legislation /rules and in particular the attractiveness of model aircraft less than 250 grammes     They also have a fair few planes to choose from .   Regards Conrad Edited By conrad taggart on 20/09/2019 17:52:39 Edited By conrad taggart on 20/09/2019 17:54:26 Edited By conrad taggart on 20/09/2019 17:55:22

Posted by Peter Jenkins on 16/09/2019 00:01:15: Conrad, I rather doubt that 45,000 potential voters will be in the same constituency. They are spread all over the UK significantly diluting this number. If we assume they are evenly spread across 600 constituencies then the number drops to around 80 per constituency. Agreed that they are probably not evenly spread but we don't know one way or another. Furthermore, since we are not all of the same political persuasion the number is further diluted. I didn't say they were ... The only thing most politicians care about is votes and how they are perceived - if you can have 40,000 votes or even 400 extra votes and be perceived as less stupid and be seen to listen - why wouldn't you take it ... People get moved on when they become a liability / unpopular at key times and they were certainly falling into that category

Err, not really... If we aggregate all of the members of the national associations together that might be 45,000, and that's probably generous. Even so that would represent only ~0.07% of the population of the UK (based on 66m inhabitants), or ~70 voters for each of the 650 constituencies. Not exactly massive numbers! This has nothing to do with any upcoming election; if it were we'd probably have seen more draconian suggestions being put forward to try and hoover up the votes of outraged Daily Fail readers whose xmas holidays were impacted by the (seemingly imaginary) drones at Gatwick. No, it's mostly just a slice of timely good luck (plus good work by the associations and their members in the campagn) that a minister has been appointed that has some actual knowledge of the space, and one who is prepared to stand up for the rights of a minority sport such as ourselves. Edited By MattyB on 13/09/2019 12:26:55 An election would have about half those number of votes and it could be tightly fought with a few percent or even less making a difference. If you are a party that is supposed to be against silly rules (the EU so called rules on Bananas etc. ) then the last thing thing you want to be portrayed as is something equally or more stupid, particularly among or largely among your own base of supporters ..

Posted by Steve J on 12/09/2019 18:02:11: Posted by MattyB on 12/09/2019 15:54:02: Had there not been a change of minister this would not have happened - responses to the “consultation” had been conclusively flat batted/ignored, with the path ahead defined in stone and not in our favour. Indeed. That's why I said 'Thanks Grant' on the previous page . I have a theory that they never intended the fee to be £16.50 (it is £5 in the impact assessment that was issued with the '16 consultation). The £16.50 was just to distract people from the other stuff and to give them something to concede so that they could say that they had listened.

Did a bit of desk research on this in the past and came across this very useful thread Posted by Simon Feather on 31/01/2018 12:05:20: One option is a spray lacquer. I have done this recently on a Seagull Zero where I wanted to matt down the very shiny ARTF, and although I have yet to fly the model (waiting for the better weather) the tests I did prior to committing were promising. In my case, I also needed something that would stick to film, and I found a couple of products that do seem to achieve this very nicely. It depends whether you really need "fuel proofing" as you would use on the inside of the engine bay, or "fuel resistance" where it's fine so long as you clean up after flying and don't leave the model soaking in fuel residue. My tests certainly showed some products have good fuel resistance. I did my tests by making a small balsa box, covering it in film, spraying it with the products I was testing, let it dry thoroughly and then put some neat fuel on and leave it for a couple of days. (I used Optifuel 5%). "Let it dry thoroughly" is very important as the fuel resistance can take some days (or even weeks!) to kick in. I'd strongly suggest you do your own tests to satisfy yourself the results will be adequate for your use, and if you do use these products, leave it at least 2 weeks to dry before running the engine. I've tried Autotek gloss petrol resistant lacquer from my local independent car parts shop at around £7 a tin, which is quite fuel proof - in my tests it marked, but the fuel did not dissolve it. It's quite shiny, and sticks well to film. I used Rustoleum Polyurethane Clear Matt Finish varnish on my Zero. This gives a lovely semi-matt finish, it seems to stick very well to film, and my Zero looks fantastic now. It's also available as a gloss finish. It comes in 400ml tins, I used about 3 tins to do the Zero (68" wingspan). You can get it in B&Q at about £9 a tin. That's a silly price, I got my stocks from sprayster.com at £4.15 a tin instead! And Sprayster have lots and lots of other very useful things like grey primer at good prices. My tests showed that the Rustoleum stuff will mark after a couple of days soaking in fuel, but it doesn't appear to penetrate. Here's a link to the product on Sprayster: **LINK** Hope this helps - as I say, your mileage may vary, and do your own tests! regards Simon

Does anybody know what make and model of glider this is please? It has 2 wings - 1.5 metres and 1.9 metres   Now that I have taken delivery it looks very much like the Ruby outlined in the article below **LINK** It has the same wing set up with 4 bolts (not per Luna and its derivatives) , it has a carbon / kevlar fuselage, it has a removable fuselage cover (I think Lunas had these but only for the electric versions ). However I contacted South Coast Sail planes and they said it wasn't one of their gliders because of the colour scheme. However, I noted in the Ruby article that it said that the maker of the Ruby, Impres Models in the Ukraine, would do special colour schemes to order. There is another big clue as to why I think it might be from the same stable of the Ruby (Impres Models) or related to it and that is the wing joiner is the same. The wing joiner is permanently connected to the right wing as per the Ruby's, which I think is very unusual and doesn't apply to the Luna and its many derivatives. If it wasn't for South Coast Planes saying it wasn't a Ruby, plus the fact that the fuselage is only 98 cms long as opposed to 120 for the Ruby, I would have it down as one. Also not certain whether the Ruby came with a V-tail. Impres models may have also produced other models in that vivid magenta colur scheme, if the Victor Isayenko Company, also from the Ukraine, is related to Impres models.   Perhaps that is where the Mystery Glider came from . Any thoughts as to its origin and name ? Edited By conrad taggart on 12/09/2019 22:15:50
