A project proving that it is possible to fly at high cruise speed and land on any small meadow and take off there with excess power. The project was without any subsidy, I paid for it all myself. From the takeoff point to the edge of the hangar is 196m. The height of the hangar is 5.5m. Aircraft STOL "DREAMTRAINER- FZ" 600kg. Engine: 1.2 TSI, gives at 5800RPM a respectable 144HP engine weight 107kg . Propeller: "Zejda 1" in-flight adjustable three bladed diameter 2066, weight 10.3kg. The sustained cruise speed of the aircraft at 4200RPM is 220km/h.

In the video you can see a failed landing with a bounce on the landing area near the edge of the forest. The bounce was due to combined effects: 1. on the terrain wave of the area. 2. also due to the inertia of the aircraft and the lower forward speed 3. due to the inefficient elevator for very short landings at the same time as the heavier engine was installed. 4. the drift behind the forest, over which the wind was blowing from the pilot's left. The drift deprived the aircraft of lift at a critical moment. In the video you can also see the bounce correction: 1. bringing the airplane to level flight 2. briefly adding throttle to deflate the tail surfaces to gain more authority at the turbulence point- the drift behind the forest. 3. To bring the airplane to stall 4. For the ROKOAERO NG or Bristell type, bringing the airplane up to three wheels and then braking hard to reduce the length of the landing is most effective. Na videoukázce vidíte nepovedené přistání s odskokem na přistávací ploše u hrany lesa. K odskoku došlo díky kombinovaným vlivům: 1. na terénní vlně plochy 2. také důsledkem setrvačnosti letounu a nižšší dopředné rychlosti 3. díky málo účinné výškovce pro velmi krátká přistání současně s instalovaným těžším motorem. 4. svůj podíl měl i úplav za lesem, přes který foukalo z leva z pohledu pilota. Úplav letadlu ubral vztlak v kritické chvíli. Ve videu vidíte i opravu odskoku: 1. přivedení letounu do horizontálního letu 2. krátkodobé přidání plynu k ofouknutí ocasních ploch k získání větší autority v místě turbulence- úplavu za lesem. 3. Uvedení letounu do výdrže 4. U typu ROKOAERO NG, nebo Bristell je nejúčinnější přivedení letounu na tři kola a poté intenzivní brždění pro zkrácení délky přistání.

Advanced pilot training. In the Czech and Slovak conditions, bush pilot training is mainly used by pilots who have a meadow or field near their home or cottage - that is, "any other surface" (which is a legal definition according to laws and regulations) with the consent of the owner and who want to be sure that they can handle it, themselves, and the aircraft without accidents or damage. For other pilots, training may be useful for competitive landing within a defined area on the deck or otherwise. For everyone else, it will greatly increase the feeling of security in the event of an emergency landing - they will know exactly what to do and what piloting techniques to choose at any given moment. You will face many real emergency landings with the engine off, where we will discuss the possibilities of the situation and choose various strategies for solving it. Let's not do anything that requires luck! And also, nothing that violates the law or regulations. Have you ever thought about what will happen if you fly over and the wind picks up, the clouds are low, and the engine fails over the forest that you are flying over? Have you really not thought about it? That meadow in the middle of the forest with the dirt road that you previously landed on so carelessly is suddenly too close, very, very small and short? Then I can assure you that your engine will usually fail in such a situation. If you hesitate and are not sure how to react, you are not sure what will happen, you are on the right track to sign up for bush pilot training. After this training, you will fly more safely, higher, and with knowledge of the area where you can always land safely, even when it's behind you! You will be confident in your abilities, limits, and possibilities at all times and in any situation. I cannot promise that you will always save your aircraft in such an emergency situation, but I can assure you that if you fly in a sufficiently strong and sturdy aircraft, nothing serious will happen to you, and that is what really matters here! You will have a huge advantage - you will not be confused, the emergency situation will not surprise you, and you will have it sufficiently trained and ingrained. With the highest probability, you will also save your aircraft. Most pilots can make significant progress after this training: they will start to perceive the lateral inclinometer in their skin, realize that the aircraft can be controlled in ways other than what they learned in basic training, fly much higher and continuously monitor suitable surfaces, keeping them in mind for possible emergency landings even if they are several kilometers behind them during gliding, and if there is no suitable surface ahead of them. Lastly, after the training, you will humbly accept the unpredictable force of nature. I promise you that this kind of training will leave a lasting impression on you, and while driving a car or walking in nature, you will evaluate various surfaces and their slope, wind direction behind obstacles, and even think about the approach or takeoff technique and suitable piloting methods. This is how all the pilots I flew with during Bush pilot training reported to me after the training. If not, then I have failed... However, so far, no one has failed to gain such skills after completing the training. Your perception and evaluation of flying will change, and you will experience what you would not have elsewhere, which will make you a better and more capable pilot. The bush pilot training is above standard and quite challenging. It is not a service provided by this aviation school and it is not entirely suitable for novice pilots. The curriculum of this training is based on my personal eighteen-year experience and is not officially approved. If you want to improve your skills in this area, I will be happy to share my expertise with you. The bush pilot training is conducted on Tecnam P 2002 Sierra and YETTI J-03 aircraft, depending on circumstances and pilot weight. https://www.letecka-skola-vysocina.cz/en/bush-pilot-training/

The actual burning that you see in the video is just the final visible stage of many degrees of burning and mixing of flames inside the burner, where the combustion occurs with the addition of pressurized air in a multiple-stage swirling flushing of burning vapors that occurs continuously inside the burner. Proper combustion can be controlled by primary, secondary, and tertiary access to pressurized air, air volume, and air pressure, nozzle orientation, and proper construction. The process that occurs there takes place at very high temperatures and pressures than the surrounding atmospheric pressure. All of this together ensures the best possible combustion! II worked on this burner for many years, developed many variants, and this one is the best in terms of operation, simplicity, low power consumption, and provides very high performance and amazing combustion cleanliness. Everything is designed so that any DIY enthusiast can make it at home from common materials found at a scrap yard. This is also described in the book. No electronics are needed! No compressor is needed either! The electric power consumption of the burner is 60-120W per hour of operation for one or two blowers, depending on the desired performance (220VAC). The burner can also be operated on 12VDC. The consumption is 1.5-3 liters of used oil per hour. Unique features and advantages of this burner over the competition: - Burns all types of oil without residue. - Burns oil mist at extremely high temperatures. - After burning, dry ash remains depending on the oil used. - It can be made from residues found in scrap yards and junkyards. - It can be made at home. - It can be made very cheaply. No advanced technology is required. - It emits no visible emissions or chimney smoke. - Any toxic substances contained in the oil vapour are burned off by high temperatures in several stages. - It has a small footprint and fits into boilers, possibly with a little modification by the user. Advantages for the burner user: - Zero fuel costs, fuel is free. - Increase in heating system performance. - Reduction of emissions compared to the original wood and coal heating - Replaces the gas burner with minimal modification to the gas boiler. - Easy maintenance and operation. - Easy to repair, any mechanic, welder, locksmith can repair. - Low cost of burner production as discarded stuff can be used everywhere. - Low cost of burner installation. Sometimes requires a slight modification of the boiler. - It is possible to operate the burner without any electronics. - The user can repair and stop everything himself.

Flying in nature from area to area freedom in travel requires more than the usual knowledge.

E-book - a paid license for a work for one person. Introductory price of 100 EUR This book provides you with a detailed description of the development and production of a conversion of a car engine into an aircraft engine, including my know-how and many production drawings and steps to follow. I will share with you instructions on how to build the lightest possible modern aircraft engine, a four-cylinder with direct injection and a turbocharger, with the least amount of effort and expense possible, and which far surpasses the performance of the 100-horsepower Rotax 912 ULS. The book will teach you how to make a gearbox and how to properly install the new engine into the aircraft to keep the center of gravity within its original limits. The 1.2 TSI engine comes very close in performance to the celebrated Rotax 915iS engine. In some applications, it can even surpass it, especially with higher torque! Higher torque combined with a suitable propeller will give you an unprecedented performance during takeoff, climb, and very high cruising speeds with low fuel consumption! These are the advantages of this engine converted for aviation." These instructions can be applied to most modern car engines, not just the TSI series from VW. It's up to you which engine with what weight and power you choose for your conversion. The 1.2 TSI engine is 100% suitable for aircraft use, including the Yetti J-03 with a maximum takeoff weight of 450 kg and the NG4 to NG6 series of aircraft in the UL 600 kg category. Video demonstrations in the attachment will give you an idea of how aircraft with this engine can perform.

E-book on how to make, operate, and maintain an oil-based eco-friendly burner. The book includes a "Production Manual" with production schematics and an "Operation and Maintenance Manual." It also contains many thematic videos that will guide you through proper ecological operation and maintenance. The burner's output is continuously adjustable within the range of 10-40kW. The pyrolytic oil burner burns any combustible liquid from aviation and automotive services, such as motor oils, transmission oils, hypoid oils, diesel fuel, gasoline, kerosene, JET A1, and their combinations, as well as even water-emulsified sludges. The burner's special design ensures the swirling combustion of only oil vapors, eliminating any non-combustible residues in the center. These are emptied every time the burner is cleaned or shut down. The burning temperature is very high, making the steel glow white and the flame in the burner burn with a light blue color when correctly adjusted. There are zero visible emissions from the chimney.

The burning temperature is very high, making the steel glow white and the flame in the burner burn with a light blue color when correctly adjusted. There are zero visible emissions from the chimney. The burner is primarily intended for gas-fired water boilers for central heating and heating of the entire service, hangar, aeroclub, offices, and changing rooms. The burner can also be operated easily as a hot air generator. The burner can also be used for melting alloys, releasing and forging. The temperature inside the burner is so high that all toxic substances contained in the oil, additives, and various oil adhesives are pyrolytically burned at temperatures well above 800 degrees Celsius. Those that are non-combustible gradually build up and bake into the ceramic layer, sometimes forming stalactites, and are then embedded into the burner's structure. After the burner has finished burning, they are knocked off and cleaned like when cleaning a boiler - they are fragile and can be crushed by hand. During proper pyrolytic combustion, the ceramic bake has a white to gray color, sometimes even slightly light brown or pinkish.
