  1. Another attempt to 'successfully' maiden the Lidl Big Bird, plus the first flight of my Mini Lidl Hawker Hunter and another small foamie rc 'jet' test. How did it go? OK, the clue is in the video title. ๐Ÿ˜” My analysis of the problems and a couple of tips too.
  2. A couple of weeks back I asked for suggestions for my next Lidl build after creating 10 big Lidl's and 4 mini Lidl's, including twins, 4 motors and biplane. I had a few suggestions, but in the end decided on something I hadn't tried before, a swept wing design somewhat inspired by the Hawker Hunter! (Hence the attempt at a silver finish (fail) and RAF roundels. She flies! Used a very cheap power train package from Banggood which has a 1104 motor, 5A esc, prop and prop saver. Works ok with a 1s and the FS2A rx. Link in video description. Very short and quick build blog and I've just seen these little foamies on Temu at less than ยฃ2. The question now, what next again? Swept wing BIG Lidl I think?
  3. Here's a quick look back at some of my last 14 Lidl and mini Lidl cheap foamie RC builds, plus a heads-up regarding my latest idea. (Hint. Swept wing.) Coming soon ๐Ÿ˜Š. Watch this space!
  4. Fair comment! I was a bit surprised just how much discussion the post has created. I did include a very small diagram in the video of cells in series and tried to explain where the balance lead is connected, but as you say, some confused comments. Just wanted to show folk that one dead cell doesn't necessarily mean you need to throw away a lipo. ๐Ÿ˜‰
  5. I know the way they are wired in a lipo thanks, I have built and repaired a good few lipos. I just didn't know how the ports were wired in my charger.
  6. I'm very guilty of speed watching, scrolling through, we all do it! I actually said in the video that had it been the centre cell of the 3 it would have been more of a pain of a job! Luckily as it was the end one it was easy to peel it off, re-solder the neg wire and put an old scrap 2s balance plug on. If balance socket leads are commoned to each socket I'll try using the 3 plug next time.
  7. I saw online that once a lipo has gone as far as zero they cannot be revived. 3.65v is less than 10% but I've done it from the low 3v mark. Worth doing for a little bit of work to have a useable 2s 800mA I reckon. I don't like chucking stuff away!
  8. You never said you opened the pack up and resoldered the pack and bypassing the dead cell, you made it sound like you only removed the balance lead.Sounds like a pain to save a few pounds. Did you actually watch the video? ๐Ÿ˜‰ You can see I rebuilt and rewired the pack after removing the dead cell? Pain in the ass for some, but I enjoy messing with stuff and OK, it saves a couple of quid too. As I said, people are posting telling me they already do the same thing. My video was intended to be educational, but each to their own!
  9. Of course they're wired in series in the pack. I took the end one off the series, so it was two good ones in series. And the balance lead and power lead attachment points needed changing to suit a 2s not a 3s. I am a qualified electrical engineer too as it happens ๐Ÿ˜‰ It's not daft and on other groups people are telling me they already do the same thing if there's one dead cell in a pack. Please tell me what's dangerous about it?
  10. Good question. Mine has 5 slots for balancing leads. It certainly senses the voltage on the power lead to see if it's with acceptable parameters for the settings you have chosen. I doubt I can plug a 3s into the slot with one dead cell and tell it that it's a 2s. More importantly there was zero volts across the power lead, so it just said 'low voltage' and wouldn't work. My charger doesn't display individual voltages either?
  11. I was thinking after using the blade a plastic spatula would be safer! I just went very carefully ๐Ÿ˜‰
  12. Plugged into my charger and because one cell would not allow current to flow through it the power lead showed zero, charger said low battery, and didn't want to know?
  13. I was testing an FPV tx the other day and like a fool forgot to disconnect the lipo until a while later. Put a meter on it and it read zero! Quite a recent 3s 800mA. I was not pleased. Checking cells I discovered that in fact it was only one cell that had gone to zero, two others were showing 3v + . I tried unsuccessfully to kick the zero cell into life by charging as NiCad, at NiMh, but it stubbornly stayed at zero. Reluctant to bin it I salvaged the 2 good cells and turned it into a 2s 800mA. Here's how
  14. That looks great mate! And I bet it goes well with that big motor. I've built 10 of the big Lidl's now and on my 1st I fitted an A2212 6T 1600kv , plus lots of carbon. It ended up quite heavy, but was fast. Nowadays I keep them light and use BR1806. Tiny little motor but it's more than enough. I've never tried painting a foamie. Worry that it'll melt the foam, mind you the Lidl are coloured foam so don't really need paint. They are great fun for experimenting with. I've got about 3 planes needing test flights at the moment, but weather has been bad for weeks. Very frustrating!
  15. My RC conversion of ยฃ13 foamie FMS Alpha jet gets its 2nd test flight after a very strange day at my local strip. Suggestions after the first pretty unstable maiden were tail heavy, but my research said it was nose heavy, hence moved electrics back a bit, added 2g of lead in the tail, plus a little more downthrust. This flight was much better than the first test, though maybe still needs a bit more downthrust? Messing about with cheap foamies can be frustrating at times, but it's a lot of fun and good learning experience!
  16. Part 2 of my Lidl Big Bird build blog and a few of my tips for anyone thinking of making a Lidl foamie chuck glider RC conversion. I was hoping to maiden it, but I think it may be jinxed, cos it didn't work out that way as you'll see in the video! ๐Ÿ˜Ÿ
  17. Finally got some decent weather to test fly my mini lidl biplane again. It flew around in circles on the maiden! I thought I'd charged all my lipos, but as you can see in the vid, maybe I hadn't. ๐Ÿคจ. Stick with it, the last flight once properly trimmed was superb. Such an easy and well balanced plane to fly now. Just over 100g with 2s 180mA lipo. Build blog is on my channel.
