What are the design principles of multi-rotor drones? The multi-rotor UAV design is a comprehensive system, in terms of structure, including aerodynamics, structure, strength, power, materials, technology, shape and so on. Through the overall design indicators, the system is modularized, the modules and the interfaces between the modules are designed, and finally the overall design of the multi-rotor UAV is realized through system integration.

A good industrial designer must be an excellent structural designer. As mentioned earlier, the industrial design of the drone is related to the overall shape, and the shape design is related to the external structural layout, so it is about the multi-rotor drone In the early design stage, the design of Tianma Starry Sky can be performed according to the design concept and design skills. Using divergent thinking, the basic content of the multi-rotor drone's use, function, structure and form is explained.


In recent years, with the rapid development of multi-rotor drone technology, there are more and more application scenarios. In military terms, multi-rotor drones are divided into reconnaissance and target aircraft. Reconnaissance aircraft are used to complete battlefield reconnaissance and surveillance, Positioning and firing, damage assessment, electronic warfare, etc .; civil aspects, such as border patrol, logistics and transportation, aerial photography, aerial prospecting, disaster surveillance, traffic patrol,...Continue Reading

Speaking of what tools are currently used when surveying and mapping, currently when surveying outdoors, especially when surveying large areas, people generally choose to use surveying and mapping drones. This is very practical and very Intelligent surveying and mapping tools when used, must also bring many different high-quality effects to people.

First, high efficiency

The use of such drones for surveying and mapping effectively accelerates the surveying and mapping work. In the past, manpower required days or even tens of days of work. It can be completed in just a few hours with drones. Effective promotion.

So most of the surveying and mapping work has been handed over to drones, which can effectively help people save workload and bring better surveying and mapping results.

Second, high accuracy

The use of surveying and mapping drones is not only convenient and efficient, but also its accuracy is very high, because the transmission image can be generated in real-time, and at the same time, the three-dimensional image can be directly given by the subsequent image generation. The data does not need to be retested repeatedly, which brings more convenient and practical surveying results to people.

Third, flexible and high

What we can also see is that with the application of various intelligent technologies in mapping drones, these types of devices are now more flexible to use, not only based on the images returned in real-time. The drone can be operated remotely. At the same time, the next mapping route can be set directly on the chip of the drone, so that the device can automatically survey and map the whole process, which is very convenient and brings a more flexible experience for everyone.

It's been over 2 years now since the Harvey flood destroyed our home. Several have asked how we are doing and if we have recovered.

We have been blessed beyond our expectations!

Everything we lost has been restored several times over. Even the oak trees! We lost 2 live oak trees my wife loved. We now have 15 oak trees and 5 nice pecan trees.!

We spent seven months in a hotel and actually survived each other! Lol

Out insurance company came thru and did not give us a bit of problem on our claim.

Everybody around us had problems with their claims. The insurance adjuster came in, looked around, got us a small check to get us going, And within 4 weeks of the inspection we had the final check.

They actually paid for all my lost airplanes and radio gear too!

But we decided not to remodel a second time. We sold the house to an investor.

As many know we were flooded the year before in 2016. We had just completed the remodel when the Harvey flood came.

While in the hotel we looked around in different areas to find a place to settle down. We looked out in Brenham. We looked up in Tomball and Magnolia. We went up to Tyler Texas.

I even found a nice home on Palestine Lake with a hangar and a runway for a full-scale airplane! But it was $750,000!!!

We didn't get THAT much from the insurance!

We settled on a small 2 bedroom brick home up and Livingston across the road from a small lake. So we have a lake view out of our front living room and family room windows. But without...Continue Reading

Here is one I decided to kit, it's one of the proposed X-15-3 Delta configurations designed to get the X-15 above Mach 7 and for extended periods. I was not able to extend the strakes all the way forward for CG/weight reasons, but it looks pretty good, is a nice big size and flies really well on long burn 24mm rocket motors. RC Rocket glider kit is modeled after the proposed X-15 modification to allow sustained flight above Mach 6.7. It features a clipped delta wing, diamond shaped wingtips. It has a light wing loading giving it a very nice glide and easy/stable boost. It comes with a plastic nose cone, 2.6″ white tubing for the body and 9mm depron wing and tail surfaces. All Foam surfaces are pre-beveled. Elevons are pre-hinged, the rail buttons are pre-installed and the body tube is pre-slotted for the wing and tail. The wing spar is pre-grooved for the spar. Length 37″, wingspan 20″, weight rtf 11.7-12.25 oz. I finished mine in white because at high speeds it would have most likely needed the ablative covering like the high speed drop tank X-15-2 version. It also saved me a half ounce of weight.

You can check how the assembly photos here to see how it goes together.
