For Li-Poly cells, the useful amp draw range for most glow to electric conversions is between 30 amps and 60 amps . Very lightweight at 21. If one is interested in optimizing Kv, prop and voltage to extract maximum thrust efficiently from the motor, consulting of charts of motor performance with various props and voltage combinations is useful to make a It’s less about Kv and propeller size than about the thrust the motor + propeller combination can provide. Let me compare it with a 4035/14 and I find that the 14 wind motor only has a KV of 299 - so you can see that bigger motors have a lower KV rating than smaller motors and operate at higher volt ranges for a Frame size limits props size, and each prop size requires a different motor RPM to generate thrust efficiently, this is where motor KV comes in. The higher the Kv and smaller the prop the faster it can correct for wind. If you have ever tried to figured out the size of the electric motor needed on a homemade or other type of RC airplane and delved into the world of kv and watts and ESC amps then you probably have a few less hairs on your head because of it.

The chosen prop combined with the number and chemistry of the cells contained in the battery pack determines the appropriate Kv. We love flying FPV & providing quality FPV gear hand picked for our pilots. This will be your approximate prop range. If you also remember to take Voltage drop into account when calculating loaded RPM, you get to a number that isn't too bad actually. 90 two stroke engines. Always monitor current when choosing prop. However the actual current that a Brushless motor will draw depends on a few factors, Kv rating, voltage of batteries, weight of RC vehicle, and gear ratio or prop size. Kv is just a way to measure relative speed between two motors of the same size, and more realistically, two motors with in the same model range. 8 SloFly or APC 8x4 E propeller and integral firewall mount. The superior power and efficiency of the brushless motor make them the ideal choice for high performance helicopters. Calling a motor a 46 and using it on a 40 glow size model may work well for a sport model that, because of the design, cannot swing a much larger prop. Description: More powerful motor replacement for . 7 Slow Fly Weight Without Battery 14. Manufacturer recommends a 7 x 5 prop on 2 cells, and a 5 x 5 or 6 x 4 prop on 3 cells. 5 prop with 3 cell batteries and 4 cell. Some will tell you it is a 5-10% decrease in current in flight and an increase of about 5% more RPM. A lower kv motor, say 700kv, has a lot of torque so you're able to use a much bigger prop. 5 inch props on 935Kv motors and review the results. Because you end up with a lower kv you can use more voltage to still get the same rpm out, using more voltage means you can get more power through the motor before it overheats, in general amps causes most of the heating, but watts Buyer: s***5 reviews: thank you RC Model 770 KV Outrunner Brushless Motor & R/C 80A ESC Speed Controller CA043; Buyer: 0***3 reviews: realy fast shipping and an article in very good condition. The motor “kv” rating x the voltage = the synchronous speed of the motor. The Power 25 is designed to deliver clean and quiet power for 25-size glow engine for sport and scale airplanes weighing 3 to 5. The prop used is based only on the Misc Maximum prop size for MT 2216-11 900kv Tiger motor. I'm getting about 11 minutes and plenty of power to lift my 550 quad along with the Fyetech FY91Q with GPS unit and my Gopro camera. I have a few 2200 3S lipos I plan on using. RE: Too big of prop? Which is easily compensated for by selecting a smaller prop, until amp draw is down to acceptable levels. This motor will provide even better vertical performance at the expense of flight duration due to the increased current draw. i use an 8x4. This is one of a range of simple motors based on a design that originates from CD-ROM motors modified with an extended pole for easy mounting, a prop shaft and a choice of sizes and winds. With increasing kV value size of prop will be decreased. KV Developers was founded in the year 1920 and has earned the respect and loyalty of its stakeholders over these decades. You are wasting amps pushing that big prop. 7 prop Weight Without Battery 15. Speed 480/500 size brushless motor, but provides much for power for a fraction of the price. The 2306 2450kv Limited Edition FPV motor, by Brotherhobby, is the company's newest offering. After several crashes, I was out of replacement props so I decided to print my own! The ones available on the internet were either badly designed or just wouldn't work for me, so I started remodelling my own, broken propeller. Whereas a 2300kv motor has less torque so the prop needs to be much smaller. The larger the prop the slower the max speed of your rig due to prop limitations but more thrust. Before Selecting a Prop, a Word About Props Only US$13. This is the Great Planes ElectriFly RimFire 1. CF1555. The motor comes as photo with bullet connectors pre-installed and the female connectors for the ESC are included as well. 1V respectively. The stator size of the Pro II line remains the same as its predicessor, but the bell has been slimmed down and opened up, and the base has been changed to an open mount with a 16x16mm mount pattern. This is my motor of choice for the full size tri T or Vtail. 4 to 2. Add to Cart At high KV any imbalances really start to show, but this one ran smooth through the whole throttle range on pretty much every prop. The Cobra 5320 motors have an 8. 2 Kg), or models requiring up to 1200 watts of power.

We suggest you choose an ESC rated for at least 20% above the max current rating of the motor (example: if your motor’s max current rating is 35A, choose an ESC RE: 2 blade vs 3 blade prop This was a classic example of not controlling all the variables in the experiment. recommends a 2200 Kv with an 6 x 4 prop but my 2600 kv doesn´t do it at all, and if I put that setup in the F 117 I plan to build will it The larger the prop the slower the max speed of your rig due to prop limitations but more thrust. helpful. 40 and . 4 and 11. Ideally the motor should be matched with a propeller that causes the motor to draw 80-100% of its rated maximum constant current. 5 grams including integral prop saver for APC 8x3. Rotor Riot 1. This new version is back mounted with an updated rotor design. Emax XA2212 820KV 980KV 1400KV Brushless Motor For 3D flat foam planes,multirotors,pusher prop FPV planes, high-speed wings . The graph may look weird because for each prop the RPM would be increased by KV to a certain point, and then increased by volts. ** product specification may vary from time to time and photo(s) is for illustration only *Suggested Average Net Weight per size is for Reference Only. KV and SON'S Consultants. The maximum tolerance in terms of weight difference for each prop in precision pair is 0. 7-4. If you have a motor, then use a wattmeter to check amp draw. Props from different manufacturers with the same size can give very different readings (which can easily be determined by the use of a wattmeter), so experiment to find the best combination for 4200 Kv Notes: A recommended motor for the Mini Funtana, the 4200Kv motor and 6.
