Kester 44 with lead, and there isn't a close second.

i was taught at the 60/40 rosin core school of soldering. or some close proximity. and iv had people preach lead free at me. iv used both, couldn't tell you a difference.

Any lead based solder made for electronics will do for sure. If you go for leadfree get something with a high silver content (3% or higher), it will make a stronger solder joint compared with a lower content silver.

If you have issues with soldering, get BGA flux

Leaded solder > lead-free solder, given a choice.

Not the cheap Chinese stuff off eBay!!

I use loctite with the no clean flux core, it works quite well but does need extra flux for dirty joints.

Hudy solder. Expensive, but worth it. It's forgiving for idiots like me and I don't have the time or money to experiment with different brand. Plus, ease of availability. (for me at least)

Another vote for Kester here. 24-6337-0027 is the part # for .031 diameter, "44" rosin core, 63/37 alloy 1lb. roll. I get mine from a place called gokimco.com, but it's usually not hard to find for 20-25.00 a roll if you google the part #. I've yet to find a solder I like better in my 25+ years as an electronic technician.

It is not that I don’t like that solder, it’s wether or not I can use that solder.
I went lead free ten years ago and most manufacturers went lead free as well especially if selling internationally.
As an ET I found that leaded solder flowed very well and had lower melting points, weaker joint strength.
I personally would prefer what works best for the task at hand, if you want a strong higher temp low resistance joint go silver. If it doesn’t matter go with leaded solder, as these solders are the easiest to start out with then once your skill increases use higher temp lead free solder.

I buy the Kester 63/37 .031" dia solder off of the Bay. I never buy a pound of it because it has a 2 to 3 year shelf life. I go to the Bay and a guy on there will sell 30 feet (1.1 oz) of the 24-6337-0027 solder for $8. This lasts me 2 to 3 years and then I buy it again. If I got a pound, it would take me 20 years to use it all.

Not trying to start an argument, but in my opinion lead free solder isn't necessary for rc cars. The difference in resistance and melting point offer no tangible benefits. If ROHS regulations had never been passed everybody would still be using leaded solder.

solder without lead isn't allowed in my house. Maybe make occasional exception for silver.

Sorry not sorry to say this; Eventually all leaded solder will be phased out.
