Brilliant model! Beautiful detail! Must be a bit of a booger for orientation in the air, being all black/Dark blue!

Well done getting the Pencil sorted out Leccy- very realistic in the air- the photos do it justice!

Now, that's what you call a vintage power supply Leccy! Very nice looking model! Many thx for the heads-up (yet again!) Looks quite similar to the one I'm showing, but yours look like built up wings, whereas this one has a curved aerofoil profile in Depron. What Rx are you using? I've still to locate one- probaly a Lemon ltwt.

Received this well built lightweight model from a fellow club member, who, unfortunately, I presently can't contact at present. To give me some more information, can anyone identify the model? I'm wondering is it built from a kit, or a scratch build from plans? 42" wingspan. 2S ESC. I wondered if it would be suitable for our indoor sessions in the local hall? Maybe a bit big? Any information welcomed!

Thanks again guys!

Thanks Leccy, Unfortunately, Tuesday is my walking day with my pal!! So won't be at the field. (And it's one of those very few windless days!!) We'll keep in touch on it. Is Root 726 still selling Lemon? I'm looking for full range Spektrum compatible lightweight receivers (reliable!) for the likes of my Pibros (motorised) delta. Also any suitable Spektrum compatible Rxs for our winter indoor session models! (No problems with JR/ Futaba sockets). Thnks for the prompt reply!

I use a Spektrum DX9 tx for flying. I wonder if anyone can suggest a lightweight 4-6 channel Rx for Spektrum DSMX txs. I did have a Lemon lightweight rx, but I can't see it advertised now. The Lemon range all appear to have cases, or have the smaller sockets. I am primarily looking for an rx that will fit standard JR/ Futaba plugs. Apart from Lemon, I'd be interested to know of any other brand? Thanks in advance for any suggestions!

Sorry for the late response. I finally found out the root of the problem. Having checked out several batteries- all on Balance Charge all at 1C I found that they were all taking a long time to charge- up to three hours! However, all of similar voltage/cell, and of similar, acceptable internal resistanceThen a fellow club member came up with the cause. There's an initial setting on the Sky RC charger, where it gives the option of DC charge current, whilst operating off AC. Mine was set as below in thee first image, giving only 5w total charge. I adjusted the DC supply to 0, and that brought the supply of permissable charge to my battery of 50w. Just recharged a 2200mah 3S 60C battery this afternoon after flying which was discharged to 3.8v/ cell, up to full charge took 40 minutes! Very acceptable. Many thanks for all your replies. Very much appreciated! And, I have to say that I have always used the balance charge mode on the charger. Boy- I've learned a lot about LiPos and charging in the last few days! ps- the bottom photo is that of a club mate's Overlander charger, which is virtually a rebranded Sky RC.

Hi Leccy, Got a lot of info, discharging and recharging a couple of packs. Unfortunately, my studies were disturbed by visitors- several readings that I wanted are missing, so I'll finish it tomorrow, and pass the info on. (other than the length of time to charge being long, I think the readings were OK.)

Hi Leccy, I'm charging a new pack presently- I'll see how I get on!

Aha! You may have the missing clue there, ED! I am using "balance charge" mode! I can't remember, but, from what you're writing, since this has just come about, I must have been using just the "charge" setting previously? So, presumably, it's OK to just charge the batteries on regular "charge" mode, as opposed to "balance charge"? If that's the case, when would I use the "balance charge" setting opon the charger with my liPo batteries?

Hi all , I have been using, with excellent results, the very efficient and versatile SkyRC D100V2 Dual Charger for the past few years. However, during my last few charging sessions, in a marked change, it's taken a great length of time to fully charge (quite a few) of my LiPo packs. Most of them have been 3S, mainly 2200mah, 40-60c- some older packs, but also two brand new packs. What used to take 1/2 hour- 1 hour to full charge, charging at 2200ma, is now taking up to three hours. The otherwise very efficient charger also has a built in internal resistance checker. Readings have been well within limits (I hope?)-7-8 ohms, and the voltages of the cells have been similar all the way through charging. Not sure why it's taking so long to charge? Any suggestions appreciated!

Hmm- pity I couldn't make it! Grr!!!

Really well done Matty I would hope and think that the stick twiddling will prove excellent therapy!👍👍 Keep at it!

All, I've decided that I'm going to go with your recommended 4-Max 5055-500kv, on 6S LiPo, along with the Hobbywing 80a 8S ESC, thanks all for the advice. (No UBEC!) I'll check on where the battery can be located in the fuselage- I pulled a pile of lead out of the nose area of my IC version when I was stripping it during the rebuild. So, I think, well forward! For interest, have any of you got any prop mfctr preferences- and sizes? I got a quotation email from 4-Max, quoting a JXF 15x8 prop. However looking at their standard advertising sales blurb, they recommend a 15X6! Once again, it would be second nature for me to specify an ic prop size/ mfctr for a .61 motor, but I need to be lead by the nose (pardon the pun!!) with the mysteries of electric combos!! Leccy, I'll have a look at the weekend at the local similar club bipes set-ups

Paul- I was present when the problem occurred- as Leccy says, would have been difficult if nor impossible to UNPLUG THE BATTERY in the circumstances that presented!!

They come in thick and fast! Usually, Tool Station, Screwfix,B&Q, etc offering free competitions for De Walt drills etc as prizes. But they're just after your monetary details!

Thanks for all the (very helpful!) replies guys. I'll go with your recommendations!

Shaun, Many thanks for all that- I'll look into them all! I'm just looking over at my invisible-6.5lb AM on the bench, thinking how much it'll weigh when I stuff battery and electronics in! One other thing- should I use a UBEC?

Hi Leccy- Glad to hear that your FW nose seems to be almost back together! As a consolation- the rest of the club were very impressed with your control of the tiny ME109, in the very strong turbulent wind! So much for weather forecasts!

I'm rebuilding my old Aeromaster biplane- electric this time. 1.2mm wingspan- +- 6.5lb. Original powered with an HP61 I know about- but- I'm consistently bamboozled with the ins and outs of electric components! I have so far been recommended to use a 5055-500kv or perhaps 5065-360kv motor, with a 6S LiPo. Can anyone guide me on their favourite brand(s) and sizes of motor, and ESC/UBEC to fit? Any suggestions/ comments appreciated!

It's a big booger, Murat- and heavy! An enquiry to 4Max may clarify thoughts on motor size, relating to a motor sze equivalent to ST2000- 2500!

Thanks again Leccy! Just ordered one!- 1700kv 2211 Brushless Motor Upgrade Parts For KT Board Foam Fixed Wing Aircraft £12.32 Sold by rightshere You should get it by 31 Jul. I'll keep you posted!

Thanks for that Leccy. Unfortunately , my original choice seems to be discontinued- from all the potential suppliers that I contacted! A right pain!

Hi Leccy, I got in touch with Align Tech, who have the motor in stock. Unfortunately, they hunted high and low, but couldn't find a mount! Looking around (a lot!), I came across this motor on eBay: 2300kv 2211 Brushless Motor Upgrade Parts For KT Plank Foam Fixed Wing Aircraft https://www.ebay.co.uk/itm/133552627004?_trkparms=amclksrc%3DITM%26aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160811114145%26meid%3D3dd64bd45ce24f53aa7d9a5a1a204623%26pid%3D100667%26rk%3D3%26rkt%3D8%26sd%3D164032563592%26itm%3D133552627004%26pmt%3D1%26noa%3D1%26pg%3D2351460%26brand%3DUnbranded&_trksid=p2351460.c100667.m2042 But a) I don't know whether it would be suitable ( smaller 2211 vs 2730), and b) since it's 3000kv, as opposed to 1700kv, I haven't a clue as to what prop to fit?? Any help appreciated, as usual, thanks!
