Mine are usually about 60% rate and 20-30% expo.what rate and expo are you guys running?

Hey Dave, that's a great looking first build, much better looking than my first! I've flown these with a variety of somewhat similar hardware to the A and F packs and here's what I've found.I am looking for suggestions for engine / esc / battery combos as being new to electrics I don't want to guess and get it wrong. I'm looking for both A and F suggestions.
Hey Dave, that's a great looking first build, much better looking than my first! I've flown these with a variety of somewhat similar hardware to the A and F packs and here's what I've found.
The A Pack's 6x3 prop and 1806 size 2300KV motor on a 2S and it was crazy weak, like 80% throttle on a fresh battery weak. On 3S it is great but pulls over 12A so that's a bit too much for the ESC. The A pack motor on 2S with a 6x4 prop is much better and stays inside the range for a 12A ESC (8A max, 300g of thrust, 40mph) . For 3S, my favorite is a 5x3.5 prop which comes out about 9A, 400g of thrust, 55mph.
The F pack has a bit larger motor, but roughly the same KV so expect it to eat a little more power and get a little more thrust. An EMAX RS2205 2300KV on a 2S with the 6x4 prop will put out 390g of thrust, 45mph at 11A. On 3S with 5x3.5, you're looking at 480g, 61mph, 12.5A. These are both right at the limit of the ESC which I've heard you want to have like 20% of fudge factor on, so if you're going with the more 2205 size motor, I think an 18A or 20A ESC is a more appropriate fit. Make sure you get one with an integrated BEC for powering the receiver and servos without having to add an external BEC. 1A on the BEC has been fine for me with 9g SG90 servos.
For battery 800-1200mah is as good range as long as you can get it to fit. The arrow's insides are pretty narrow so be sure to check that measurement on the battery you're looking at. 1000mah gives me about 12 minutes of flying around (although I am a pretty tame pilot still).
I would say my go-to setup (and what I have in the Goblin now) is an EMAX RS2205 2300KV, with a 20A ESC with integrated BEC, 3S 1000mAh battery, 5x3.5 or a 5x4 prop (2 blades). There are a ton of combinations that will work just as well though, because there is a ton of overlap in what you get as you mix and match various parts.

Thanks Captain!Hi:
My sons and I have three arrows and use those motors with 30 escs with great success. We love those motors and they are pretty durable too.
Awesome! I have been flying this Mini Arrow since it was released. Fly it every time I go out. Has taught me a ton. Everything from aerobatics to throttle control. Love it.Made slight modification on my arrow, so I can secure HD cam on it
Thanks, It does aerobatics nicelyAwesome! I have been flying this Mini Arrow since it was released. Fly it every time I go out. Has taught me a ton. Everything from aerobatics to throttle control. Love it.
