So today, I was reading about a kid who got a custom prosthetic arm printed like really. Holly molly! People are printing prosthetics nowadays! That's when I stumbled upon Curewith3D, and wow, 3D printing in healthcare is on another level.

Apparently, I found out that they're not just 3d printinghttps://curewith3d.com/ limbs. They actually use patient-specific scans (like CT/MRI data) and some DICOM files to design prosthetics that fit the person's body perfectly. Every angle, curve, and dimension is matched to the individual. No more bulky or uncomfortable fits.

What's wild is how fast and affordable the process is. Instead of traditional molds and weeks of waiting, Curewith3D can design, print, and deliver a customized prosthetic in a fraction of the time.

I didn't know 3D printing services could be this life-changing, and it's happening right here in India. It really makes you wonder what else we're going to be printing next.

Anyone else heard of this or know someone who's used a 3D printed prosthetic? Would love to hear more.

Hi,
Is the offer still available

So, except for the extra waste of money a 30C battery won't negatively affect the Tx (which originally comes with a 8C battery)?

Quote from: Dawner on July 01, 2025, 08:08:14 AMMy RCB OS10 has a 2200mah 7.4V 2S 8C battery. But I can't find the exact replacement. So, Can I use a 2200mah 7.4V  2S "30C" instead?
I have very limited knowledge on Batteries. Please kindly elaborate on the Specs. Thank You

Here are some battery basics:
1. A 1000mah can provide 1000ma or 1amp current for 1 hour
2. 30C means you can draw max 30amps from a 1000mah battery (usually for shrt bursts, not continuous)
3. If you draw 10amps current, a 1000mah battery will last 6 minutes
4. Normally we don't use more than 75% of the capacity before recharging
5. Nominal voltage of a 1s (single cell) lipo) is 3.7 volts and 4.2v at full charge. So 7.4/8.4 for a 2s.
6. If not using for several weeks, store at 3.85v per cell (50% charge)
7. Avoid draining below say 3.5v per cell

The current draw of an RC Tx will be of the order of 100ma (55ma quoted in Flysky I6 specs)
So a 1000mah battery will get used at the rate of only 0.1C, ie, it will last for 10 hours in theory. Or at leasr 5 hours in practice.

For use in a Tx, large mah capacity and high C rating is a waste of money.

So buy a 1000mah 2s of the lowest C rating that you can find.
Check the size to ensure it'll fit in the Tx.
Check for matching connector so that you dont have solder a new connector to the lipo. Cutting the lipo wires and soldering a new connector is DANGEROUS and requires CAUTION. 2s lipos usually come with a Jst connector, which I think is what your Tx has.

Hope this helps.

Can you share a new link so that I can join the Group?

Hey guys,
Just bought a new fs2a receiver. Was hoping to bind it using a bind cable. But in any tutorial i see, everybody's using bldc esc. I do not have a bldc esc since i only have been working with coreless motors. Is it really necessary for me to buy bldc esc? If not then how do i bind this receiver?
Thanks in advance
