I thought the 6" was where I would see the most impressive speeds from the QuadStarDrones ARX-R design, but it seems the 5" is where the sweet spot lies. The 6" has been "an education" to tune, but the 5" feels more locked in to me than any other quad I've flown to date.... ON STOCK BF 3.5.7 PIDS! I have only taken this one out 3 times, but I can see that getting near 200MPH will be no problem with these HyperLite 2207's. I spoke with the folks at PyroDrone, and along with the advice that Ryan (from QSD) gives on his blog (specifically that what you need for top speed is RPMs) they steered me to these 2207 2722KV's. I love them. I can't wait to see how they perform on "normal" frames. They have that punch of my HV's but they feel LITE! The Aikon F42020 is what I thought I was buying...instead it was the F4 mini Aikon that I ordered. It is fine and performs well (I haven't fallen out of the air, so...). The ESC is the AK32PIN, and that is what I ordered and the more important part to me between these two components because I'm running 4 or 5S (Venom power is the illest). I just got some (HQ) V1S for an older quad of mine, and they perform so well on that rig and my 7" Ti LR that I decided to try them on this one. I got some also for my 6" (ARX-R) and have yet to take it out on them. The HQ Props are crazy amazing. They really are in a class by themself oftentimes. I'm not gonna point other companies out, but many could learn a lot from HQ. I'm betting my "great stock tune" is more likely "great propellers". What is it like to fly? Well I'll say this: imagine driving a car with power steering, and then trying to drive a car without power steering AND three-on-the-tree. The ARX feels "free like a bird". Once you go back to "normal" frames you can feel the stiffness and how they are very "in place" and limited to their angles of attack. My ARX feels like you are very at your whimsy to make any sudden movement. This is all kinda unbelieveable because it... is... FAST!
Thanks to the folks at PyroDrone. It is hard to believe they would answer a "can you suggest a motor to me?" question, but they do not ever seem to mind taking care of the customer before and after the sale. There is a reason this is my 3rd quad built in 2 months with Hyperlites. That company and their products... I love 'em!
Finally, mad props out to Ryan Lademann at QuadStarDrones for coming up with a killer design and having the set to produce and sell it. Ryan's a great cat with super communication, and his product is sheer genius. We all know the camera angle being nearly 90 degrees increases your capability for speed, but arranging that in a package safe enough to fly AND land is difficult. You sir are a real credit to our craft and I for one sir, salute you.

Try the APC 5x3.7x3 props. By far my favorite 5" props for anything but racing. I race my ARX on HQ 5x3.6x3 just because the durability is nuts.
Cool build! I hope your instinct on touching 200mph is correct, lets wait for the data.
Can you point me to the link where Ryan specifically writes that upping RPM is the key? Cheers.
Sure thing bud. He says it here: https://quadstardrones.com/portfolio-xlr-1/ . What he says is:
Less drag = more speed (less force needed to push through air)
More speed = props less loaded (blog on prop unloading is here)
Less loaded prop = less torque needed to spin props
Less torque = more RPM
More RPM = more speed
Steps 2-5 repeat seamlessly up to the “terminal drag” point
... I've read Ryan's blogs front to back a few times.
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..
Read moreWith the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

If you're going for pure speed, you can't beat the APC 5045 bullnose or the APC 5260. Nobody believes me til they try them. I would lean more towards the 5045 with that high kv motor, but you might as well try both, right?
THAT'S RIGHT! =]
And the APC 5046? Same bullnose prop but 0.1 pitch more.
I got 'em on the way! Thanks for the input MANI and Ryan!
Yes :)
OH YEAH! Got my APC delivery! Now... I just need this tornado weather to move on so I can try 'em out! They look like serious business.
OH MAN! I did not think that a prop choice could be so dramatic! I do not think that any of my quads go as fast (top speed) as this ARX is off the launch pad! I had a real issue trying to "get it down" that first time. LOL. I thought at the very least the tune would be horrible from the V1S to the 5260's, but NOPE.... smooth as glass at insane speed! Uhhhh yeah; THIS is what I was looking for! I am gonna have to sample some more of these APC's.... I need a drink + dab. That was exhilarating.
Welp.... I guess I have to buy some 5260 now
Got them in the mail yesterday, awesome quality, didn't fly them yet.
I'm about to stock up now that I've seen the difference. I sent them an email for a suggestion in a 6" (something like the 5260?). I'm going to try some of their 3 blade too.
The 6" tri-blade is amazing. I cruise at around 60-70mph at 35%-40% throttle on theose 6042 tri-blades
OK... I got those and the 6043 and 6045 2 blades. I got the 5150's you told me to get before and some 4040 (for my Gecko) and 5040 tri's just to experiment with.
Got some of those too!
