All other things being equal, a skinny fuz will make a considerable difference. More speed and energy due to reduction in drag. I am surprised that 90% of drag comes from the wing!
-
Odd i always thought the VoltiJ was quite quick but the fuz was awfully prone to breaking i remember Carpet Pete flying one in an F3F at HOH and getting a 42xx on par with the rest of us with our f3f kit

Oh yes sorry, it's 6th to 7th July. I put the date in the calendar section but not on this post!
-
Is it a secret?
-
Yes I'm afraid so.
-
"It's alive!.." That's good to know, thx.

They are £50 each or join and you get a couple free.

Has the date been fixed?

I recommend setting the alarm for 5.0v for a 4.8 (4S) Rx pack. Nixx packs are totally different from Lixx, you don't want to go below their rated voltage. A 1S 3.7v LiPo has a working range between 3.6 and 4.2v A 4S 4.8v NiMH can charge up to almost 6v but you don't want to let them get below 4.8v Tony

anyone tried the Zap Goo from the US: Zap Goo PT-12

So after a bit of a delay the Goop has finally arrived, clearly the delivery driver doesn’t understand the words “fragile” but the tube is intact. I note it’s being offered by another seller in Ireland for £5.99 for 110ml tubes which makes it even more of a bargain, the 30ml tubes are £3.99! Now to begin surgery on my Gulp DS

Yep - Aresti is heavier & more heavily loaded (from what I've read) Yep - I also use steel wing joiners for that little-bit-extra - have flown it in 50+mph winds - ballast would help energy, but at the risk of destroying the wings, which are built light with no spar. Phil. link below - flying in a 55mph wind - flying was ok, launching wasn't - crazy...

Thanks Mike ! Phil.

Yes that makes good sense about try the waggle stick approach :). Will give it a go thank you.

No need to check Tx batteries. I don't use telemetry so I missed the point - sorry. If you can see the Rx voltage on the Tx display, why not put a recently charged Rx battery in the model, waggle your sticks in a frantic way to draw max current and get a feeling for what the lowest voltage is under load. Then you can set you alarm a little below that as a starting point and see how you get on in practice. Batteries with a lower capacity, like your 300 mah pack, will drop their voltage more under load and probably need a different setting for the low voltage alarm. Another consideration is that your gear will quit working if the voltage goes too low during a high current demand, causing a so-called, 'brown out'. The battery will recover if rested.

Would love to spread the BARCS lurve... Does BARCS sell them?

Thanks mike. I was referring to the batteries inside my gliders which all run at 4.8 volts. I can check my tx battery if it helps.

Big thank you to Pete Allen ,Chas, and Mike plus all the helpers beavering away in the background. Possibly the most enjoyable IG to date . Obviously helped by the UK weather and a challenging flying site. Good accurate report from Steve . I spoke to Julian during Sunday's lunch break and he admitted he could not cope with the UK conditions on Sunday. Congratulations to Steve for a well deserved win . Thanks again Peter G

3.7 volts is the nominal voltage of a single Lipo cell. Nimh technology is different and the two type Lipo/Nimh need very different charging procedures. Your Nimh 4.8 volt packs each have 4 cells. The Nimh cell has a nominal voltage of 1.2 volts. For a 4.8 volt Nimh pack, what's a sensible lower voltage limit under load? You'd need to get an opinion on that from a person who knew your equipment. Are you sure your Tx runs on 4.8 volts?
-
3Very helpful thread, thanks. Question if you please: I'm using a combo of 1600/950/300 NiMH batteries all running at 4.8Volts. Should I set alarms ringing through my TX when voltage drops to 3.7 as suggested above? I have noticed how under load the battery life bar on TX drops but pops back up to almost full when resting after a bit... I haven't kept an eye on the volts though.

I'll stick my useless opinion in. I do as Paul. Although I very rarely take a spare battery to the field, especially if in the plane it's shoved right down into the nose and there's leads in the way etc. I use the ISDT Q6 charger and power it with a 3-4s Lipo and top up or charge at the filed. I charge between 2-5c so they take very little time. Although I already had this charger set up, would be cheaper to buy 2-3 1s batteries to take to the filed if you're charging at home. I try to fly most days if the weather is kind, I rarely store at 50%, my packs are either fully charged or at 3.7v after a flying session. These 1s lipos are dirt cheap, if you shorten its life from leaving fully charged it's not much of an expense to replace. And it's 2019, I don't buy into keeping your packs at 3.8v while in regular use or only charging 1c, my packs at 5c charge stay stone cold still and I have never noticed any degrade in performance from any of my batteries from a 1s up to the 4-6s packs I used to use for freestyle quads. Rx batt telemetry on my radio and stop flying at 3.7v. I've never put a 1s lipo on a battery checker.

Thanks for the useful replies. Particularly good to know about not storing fully charged.

Hi SP Interesting idea, but I don't think including a model, probably sourced in the EU, and currently under threat under threat of extinction due to drone legislation, would have the same cachet as an "Ax strung loose, and an amp with volume control showing a maximum of eleven" do you? Don't worry, Glastonbury's nearly here....... OR Jimi, where are you man? Your public really needs you now bro! Mellow thoughts guys! Regards Pete BARCS1702
