Despite the naysayers there is nothing wrong with soldering cells if done as per Wojtek's tutorial. Very little heat rise when done properly and a decent spot welder aint cheap either! Hey if it works for Wojtek who probably has more experience with these things then any of the rest of us it's good enough for me. One can't argue with success! Keep up the good work my man!
Yes, the Most important factor is to use the right gear. For Soldering these batteries You just need a good high-wattage Soldering iron.
@@unknowninvictus2520 What is "good high-wattage"
@@MACE1-1 Watts are secondary, the most important is high temperature capacity iron. It has to be at least 10 mm thick to store enough energy to quickly transfer it to the cell. The speed of soldering is the key.
@@MACE1-1 I have been told (and use) at least 80 watts or ideally 100+ watts.
Where could i find this tutorial?
Wojtek, where you been? Very good to see you and appreciate your advice as usual.
I'm always watching your great videos.
You are amazing.
The only difficult thing is...
Wemotec duct fans are too expensive and even harder to buy.
That was some great down-on-the-deck low level flying! Great job on the camera, too!
Always enjoy your inspirational videos on different setups!
Yesterday I flew my Viper 90 with a het 1680kv motor jetfan v3 on 10s.Super deep sound and incredible speed with 4 min flight time.
Lipo weight right at 1000g
Fantastic flight and super cool sound! love your builds!
Great video ! Informative and inspiring as always. Thank you for sharing your expertise & Greetings from the UK.
Great to see you again! I have this exact Avanti.. I wish it sounded like yours!!
Ballancing edf is the key.
Super exciting flight..awesome,greeting from Penang,Malaysia
Very good explanation on the type and soldering of the battery's, very nice flight, greetings from Remi Belgium
I strongly disagree on some of the battery considerations and nickel strips. There are several thicknesses, and I have been using a pack of 6s3p VTC5A on avanti, with over 90A continuous (stock freewing motor, newer version) with no heating problems and great success. Just use 0.3mm thickness and use one per element.
It is also possible to solder single string copper wire over the nickel strip if needed. I have done that a couple of times. The cells receive some heat but way less than directy soldered, and tin sticks very well to nickel, no so well to aluminum.
Awesome sound as always. A bit underpowered for my taste though. Specially compared with some of your older videos with the same plane.
Super Setup! So macht das Spaß. 💪
Amazing 👍👍👍👍
Greeting from Sydney
Let us know when you setup a factory in the USA selling these 6S LiIon batteries. 🤩
That´s interesting! I must look more in depth in that. I thought LiIon couldn´t manage too much current. A couple of days ago I saw a RCGroups member in CZcams "Deadstick..." flying his Jets with giant LiIon batteries for almost 30 min. Thats crazy too....
So true! Great video.
This setup is interesting, but more from battery testing perspective, then actually flying ;)
I have also spent a lot of time tuning my Avanti with different powers system.
The sweet spot for me is Wemotec 80mm with HET 1340kv on 12S, using two 6S Molicel P45 packs in series and a T-Motor Flame 60A ESC (just 70g!). Just marginally heavier, but it has thrust to weight ratio way above 1 and can easily go 200kmh+.
Sweet setup :)
Excellent video and information!.
Excellent flying and video. Who needs a turbine when you have a beast like this?
Wunderbar!
Nice to see you back experimenting, and I like the new approach- a lightweight 6S set up. Just to clarify, so on this flight you had one of the 450 gram batteries, not 2 of them in parallel? It would be helpful to see the placement in fuselage if you do another video on this arrangement🙂
Yes just one and it was almost all the way to the front. About 4cm back from the front of the plywood.
@@EDFjetRC thanks!
Awesome aircraft and very smooth flying. I'm on the "fence" between this beautiful EDF and the E-flight Viper 90mm. I like the Viper's airfoil greatly, but the Aanti 80mm also looks like it has a very nice wing load. If I did get the Avani (or maybe the FUTURA 80mm) I'd install a Spectrum AR637T.
Flew the Avanti 9 times today on 6s9000/7s9000 and wow I like these P45B cells!!!!!! Set LVC to 2.7v but start landing when you are at 18/21v.... but 2.7v under full load. Consistent 8000mAh used. Barely warm. 6s =10min, 7s=11min
It's there to see guys... these cells are super strong....try them!
A video for the six cell pack described would be most helpful illustrating soldering and placement of the copper strips, balancing leads and power leads.
You can sandwich copper under nickel for greater current carrying.
I just started assembling different sized 6s, 7s and 7s2p P45B cells to use in my 70mm&80mm Avanti, 80mm Futura and 70mm Habu SS. Bench testing I'm getting @55 A continuous and cut-off of 3.0v at @60-65C...... 3800mAh used. I use 0.1x20mm copper and 0.1mm nickel spot welding..... 2P is 0.1x 40mm wide copper which equates to @11ga copper wire.... more than enough for 150A bursts and 110A continuous on 6s2p~8s2p..... every P gets an extra 20mm wide copper.... meaning 75A/Parallel. My Odyssey 16s4p18000 will be able to do 300A bursts and @225 continuous.... that's going to be a lot of fun!
@@TheLowelllife which table or information do you reference to find the current carrying capacity for copper.
@@TheLowelllife That Odyssey is gonna RIP the sky !!!!!
15 minutes... wow!
Nice super light setup! Should every rookie pilot as me try:)
Nice setup sounds great.. can you make these packs up for people!! 👍
Where do you live?

This is a very interesting approach to the bigger-is-better we see a lot. I'm very impressed with your video and would like to see the "15 min" flight just for fun. Questions: How do you keep the amps down to 55A max? Can this be done in a budget friendly way, for example with a standard 80mm Freewing EDF? Love to hear your opinions.
All you need is an electric clamp meter.
Set up your model on a stand and connect everything. Then set the clamp meter around one of the ESC lead cables - it will then dynamically show the AMP value flowing through it.
Then start adding throttle and notice the AMPs rising. When the value reaches yoru desired number (55), notice the throttle value.
Then in the settings of your Transmiter, set the MAX output value for throttle for this value.
This way, you will never exceed it.
Just DO NOT calibrate your ESC after that, as it will readjust its max value.
Actually you could use the ESC live telemetry if you have it instead of the clamp meter.
I use this also when I want to run a motor with a higher voltage then it is rated, but keep the total power within limits.
@@adamtrzaskowski3901 Thanks, I figured it would be a matter of choosing the right components (EDF+motor) that would decide for what max amps. The chosen motor here is 950W continuous so about 45A on a loaded 6S. I have an inline meter thingy that I can use to "calibrate" the max current with.
The stock Avanti (normal motor) has about 70A on Li-ion 6s so not much more. I would not go the partial throttle way as it is not efficient with electrical loses. Better way is to set ESC timing to 0 degrees or other minimal timing that smoothly spins the motor and the amps will be lower and motor will run efficiently.
@EDF Jet RC I am also using this battery, they are brilliant, Could you share the STL for the Pack holder? Thank you, love your videos.
really interested to see what this airframe does with the stock setup
Pretty much exactly the same, and thats using 1700+ watts
Do you think you could fit a 90mm fan in this jet? I have an eflite viper setup I was thinking to put in one of these arfs.
Can we have more info on the plastic parts you used to cover the Li -ion batteries? Are they 3d printed?
Nice setup 👍 do you think a toroïdal rotor could be a god Idea to explore ?
not in EDF application.
What was the total weight buddy?
hey woztek .... what was the total weight of the Avanti with this setup
Nice flying, bad landing.
Has the EDF sound been edited/enhanced ?
What current sensor did you use in combination with the frsky receiver?
New FrSky FAS40 ADV, very accurate and reliable sensor
@@EDFjetRC How were you getting such high current readings? Why did you not use the FAS100?
@@EDFjetRC HI Wojtek, that model in theory only registers up to 40A, right?
Please clarify this point for us, it is strange that you are not using at least the 100A model.
Only a 60amp esc wow
Is 2 mm2 enough for 50 amps ? According to what I see on current carrying capacity you need about 1 mm2 for 10 amps. Where did you find that 25a per 1 mm2. I'm not really trying to be disrespectful just trying to understand what you are doing. I am very interested in using these cells for RC
It worked for me well up to 140A for 7-8 seconds or 50A for 5 min flight.
@@EDFjetRC maybe the tables are wrong as they are probably made for general/ house wiring and therefore super conservative for battery connections that are not long.
Sir which is suitable battery for 70mm-6s motor???
For flight time 5-6min
Please reply me sir???
cg 120 mm?
