Frequently Asked Questions
***Note: If you have a question that is not mentioned below, please feel free to contact me. But please be mindful that I sell a lot of models and I probably will not remember what model you have and what flight controller you are using. To speed up receiving a specific answer to your question, always mention what model and what flight controller you are using.
1. What is included with the DIY kits?
DIY kits come complete. Everything is included to build the model. To complete the build, you need hand tools, a soldering station or a good soldering iron and your own receiver. Nothing else. To be clear, you do not need to purchase anything else. Below is a video explaining what comes with a DIY kit.
2. Can I get an RTF, turn-key model from you, fully set up with radio, battery and receiver installed?
I now ofer ARTF models. This means almost ready to fly. The models ship with a radio and with the receiver installed. The radio is configigured for you as is the flight controller. All you need is batteries. To make your kit or RXR build almost ready to fly, you need to add this item to your shopping cart.
3. What batteries do you recommend for my model?
All of my models do well with 3s, 2250mAh, 35c batteries. For the acrobatic models or for the acrobatic pilots, such batteries are ideal. If you are more interested in getting long flight times but not necessarily acrobatic performance, you can go up to 3300mAh batteries. Models will be more tame and a bit less responsive with 3300mAh batteries, but flight time will be significantly improved.
4- What is the expected flight time for the model I am interested in?
Based on the answer in question #3 above, flight time will vary between 5 minutes and 10 minutes. Note that flight time also vary based on flying style and battery quality.
5. What size propellers do you recommend?
For the 226 models, 6 inch propellers are recommended. For the 258 models, 7 inch propellers are recommended. For the 355 models, 8 inch propellers are recommended.
6. What is the lead time on a custom built model?
Lead time varies. The average is 7 days, often less, and sometimes longer. After placing an order, you will be contacted and I will inform you of the lead time for your specific build.
7. Do you ship to my country and what is the shipping cost?
Yes, we ship anywhere in the world. Shipping cost on any and all orders is 5$. Yes, you read that correctly. Only 5$ shipping on all orders world-wide.
8. Your models are very fast. Is there any way that you can build a tame model for me?
Of course. My models are governed by the settings in the flight controller. Tame settings make for a tame model. All my models ship with fairly tame settings, but you may request extra tame settings if you are unsure whether you can handle my models or not. Simply touch base with me via email.
9. What flight controller would you recommend for a beginner?
The KK2 flight controller is the easiest controller to get around. It's easy to setup and it is easy to adjust out in the field. Not to mention you do not need a computer, nor do you need to learn how to use a computer software. The KK2 is easy and it offers plenty of performance to satisfy new comers to hobby grade quadcopters and advanced pilots alike.
10. What is the difference between the flight controllers you offer?
The KK2 has the edge for convenience and ease of setup. The Mullet has the edge for acrobatics flying, and the Multiwii has the edge for stability. The Multiwii is also the only flight controller I sell that sports a barometer, a magnetometer (compass) and the ability to add on a GPS. In terms of ease of use, the KK2 is first, followed by the Mullet, and the Multiwii has the steepest learning curve to it.
11. Can you install a GPS on my model?
I do not install GPS units and I do not provide support for GPS applications. This is something that may come in time, but at the moment, installing and configuring GPS units is something that is left for end users to do themselves.
12. What model do you recommend for me?
This question comes up a lot. Folks give me a rough idea of what they intend to do and then they ask for a model recommendation. This is a very difficult question to answer because it is very subjective. Some guys prefer a larger model, other guys prefer a smaller platform, for example.
So instead of choosing a model based on your interests, here are some things you may consider to help you make that decision for yourself.
A- Larger models tend to be a bit more stable and the larger size also helps with retaining orientation in flight. Models that use 8 inch propellers are also capable of lifting a heavier payload.
B- Smaller models are more nimble and they make for more aggressive acrobatic platforms. The smaller air frames are also more sturdy if you hit the ground in a crash.
C- Armattan currently offers three models that have a lifetime warranty against breakage on the frame; the CF models. These are the CF226, CF 258 and CF 355 quadcopters. So if having peace of mind when learning or when flying aggressively, these models are great options. Fly it, crash it, break it, and we'll replace it!
D- Tricopters offer a unique flying experience as they have a tail servo which provides a much different feel when flying. However, the tail servo doesn't take well to hard crashes. This is the case for any tricopter on the market. So if you are new to the hobby and bound to crash a lot, perhaps this is not the best model for you. But if you like a smooth flying platform that offers a very interesting control, and if you think you can keep the model in the air, then this is a fantastic choice. Note that servos are not all that expensive, either, so get a spare servo or two when you choose this option.
E- Finally, the V-tail is all about "cool" factor. It looks great and it flies well. But more importantly, it provides unequaled visibility. The V shaped tail makes it nearly impossible to lose orientation so this is a great option for guys who like to fly in larger areas where they push the limit of visibility.
