x642 or M545

[jakevisser10]

I just ordered a leopard 4074 2200kv with the 180amp esc. I plan to run this all on 4s with 6mm bullet connectors on everything. I want to get around 50 with good run times (3-5 minutes), while keeping everything at a safe temperature. Which prop would be best for performance and temps? Feel free to suggest any props for this setup!

They will be very similar................... both good choices for 4s.

I'm going to start with the x642 and if temps are good, then I will move up to the m545
