Q: Can you ship to anywhere in the world? How much will it cost?
A: We offer shipping to most anywhere in the world! As for us being able to tell you shipping cost right off hand, unfortunately we are unable to give you exact shipping charges, however if you would like to know what they are please proceed with your order and before it asks for any type of payment our system will tell you exact shipping charges to your location.


Q: The country where I live isn't on your list when I try to place an order, why is this?
A: Unfortunately we must generally decline to do business with customers located in a small number of countries that provide limited assistance in investigating and prosecuting fraudulent orders and identity theft. If the item(s) you wish to order are under $500 including shipping and you can agree to make payment either by PayPal or Bank Wire Transfer, we may be able to assist you if your specific order is approved by our store management. If this may be acceptable, please let us know by contacting our order support team either by clicking this link or visiting www.scaleflying.com/support We'll try our best to assist you in completing an order.

In the instance of customers living in the United Kingdom, our shipping system requires that you provide your specific location to optimize package routing, such as England, Wales, Scotland or Ireland.

Q: An item in my order was damaged during transit and I had insurance, how do I get a replacement?
A: Please contact our support staff using our online form to begin a claim for your insured package. Our insurance provider, U-PIC, requires that you send us a signed letter describing the exact damage that happened and what specific RC Aerodyne order number it relates to, as well as the date of postage on the package label and the day the package was delivered. Please also send us photos of the damaged item(s) if possible as this can help speed up claim processing. Once we have the required materials to file a claim for the parcel, it typically takes 10 to 20 business days until claims are approved and we can send you replacement merchandise or issue a credit.



Q: When I try to order using PayPal checkout, I receive an error message saying a phone number is required and cannot complete my purchase. How can I submit my order using PayPal?
A: Please verify that you have a phone number associated with your PayPal account. When you use PayPal Express, your shipping address and other contact information is automatically submitted to our checkout system from PayPal, and we do require that a phone number be associated with all orders so as to allow us a way to contact you if there is a problem or in the event we are unable to reach you by email. If a phone number is associated with your PayPal account and this issue continues, please contact us by opening a support ticket and we can work with you to complete the order using a PayPal invoice request or via a different secure payment method such as Bank Wire Transfer, Money Order or Personal Check.




Q: What is the difference between weighted and unweighted scale rotor blades?
A:
Unweighted blades have less flex then weighted. You want more flex when you have a multi-blade rotor head. This will give you better overall stability.



Q: When using a multi blade rotor head, do I need any sort of stabilization system?
A:
You dont need one, but it is highly recommended. Without a multi-head gyro your helicopter will be very unstable in the air. We recommend the Skookum 720 or 360. The 720 is a full 3 axis gyro incorporating the tail as well. The 720 also doubles as a receiver if you have a spectrum radio. For those of you who already have a tail gyro, you can use the sk360. This is a 2 axis gyro that is capable of stabilizing just the rotor head/swash plate.



Q: What other types of 3 axis gyros will work?
A:
Most of the flybarless gyro systems on the market will work with multi-blade rotor heads. The gyro really does not care about the rotor head or how many blades you have. Its job is to stabilize the swash plate.



Q: Are there any modifications I need to do in order to run a multi-blade rotor head?
A:
Lets keep in mind that in order to spin more than 2 blades takes more energy/power. In some cases such as a 3 blade it may not be so important, but when you start thinking about using a 4 blade or 5 blade, this takes some serious power and torque to run the rotor head.

Lets take for example our 600 size Blackhawk. The fuselage weighs just less than 2 lbs. with weapons set. If you choose to fly this fuselage on a stock align or chaos 600 helicopters, using the stock rotor head, you should be just fine without any modifications. If you choose to add the 4 blade rotor head and possibly the tail, there are some factors that need to be addressed.

Motor: Because you are using a 4 blade rotor head, the rpms needed to fly the helicopter are much lower due to the increased lift of 4 blades. The problem when you use a stock 600 set up with 1100kv and 100 amp esc is that the kv/rpm will be too high for the rotor head and will also require too much torque for that stock high rpm motor to handle. If you do not change these and choose to run the stock set up with a multi-blade head, it may work at first, but you may find that your esc and motor will be quite hot and flight times decreased significantly.

In our Blackhawk we have used primarily two different types of motors. A560kv and 630kv motor. The 560 kv would be used with a 12S set up and the 630kv would be used for a 10S set up. This gives us about 15 min flight time with two 6S 5000 batteries wired together to produce 12S 5000mah. Basically in this set up, anything above 8S would be a high voltage system. High voltage systems result in greater efficiency , less heat generated, longer flight times and longer longevity to your electronics.

ESC (Speed Controller): The speed controller I typically use is a Castle Creations HV controller. In our Blackhawk set up, because we are running 12S, the amps used are very low. Its basically sipping the power from the battery packs. The Castle 80HV is adequate unless you decided to fly 3d with it,,( not recommended )

Batteries: Lets keep in mind that we are not flying 3d so the C rating is not as important as flying 3d. It is ok to use a 20-25c pack when flying high voltage systems. There is plenty of power on a 10S or 12S system, so the C rating is not so critical. This will also save you money as well. However, if you have 6S packs of a higher rating from maybe your 3D helicopters, this does not hurt to use a higher rating.

Separate BEC: Most speed controllers now have a built in BEC (Battery Eliminator Circuit) I highly recommend using a separate BEC unit. The reason is the speed controllers tend to be pretty reliable; however, if your speed controller should fail in flight, this could result in the inability to control the servos.

Because of the high demand and stress of the speed controller, its just safer to use a separate BEC to power the receiver/servos. Why take the chance on such an expensive machine.

So typically I wire the BEC onto the connector that goes to the battery / same side as the wires from the ESC . Then plug the BEC into the receiver. Most BECs have a universal or / JR connector for this reason. In the Blackhawk build, we used a Castle Creations BEC Pro 20 amp. Anything above 10 amps will work.

Flight Times: Remember that more volts = less amps drawn = less heat = more flight times. We actually tested our system until the batteries ran down; this was 18 minutes of flight time. Please dont do this, its not good for the batteries, but usually people get tired after 5-7 min of flight time, so 10 minutes is easily obtained. This is a good point to start thinking about landing.
