The predictive communications range models were refined using specific antenna and system characterization data measured in a compact range facility resulting in a detailed link budget useful for addressing BVLOS command and control requirements. In addition to the vehicle performance assessment, Friis-based models are introduced to provide a pseudo real-time communications link range assessment. Flight-testing methods and results are presented demonstrating the capabilities of these algorithms, with results from a unique test-case involving an unintended fault during the record flight. Range and endurance estimates are developed using a novel real-time system identification algorithm onboard the vehicle for aerodynamic parameter estimation, and propulsion system characterization. If you are wandering why the cables are outside of the fuselage, thats just me being lazy, you can also put them unseen inside.This paper provides details on best practices for vehicle design for BVLOS missions, with a focus on robust control links and real-time health monitoring.The development work presented herein focuses on a specific mission to set the speed and distance world record for a fully autonomous vehicle, requiring development of analytic tools for estimating vehicle range and endurance, as well as models for predicting command and control link integrity while operating BVLOS. Make bevel cuts on the vertical stabs so that they make a V Glue on your canards and vertical stabelizers. Glue your wing on and glue the two sides together. It doesnt deliver extreme performance, but it stands out in the crowd and delivers extreme fun!įirst, make two bevel cuts and score cuts, so that you can fold these pieces inwards which will guide more air to your propįoldover the paper and Install this piece Its the perfect parkflyer and an eyecatcher at every airfield. But if you can fly, the Kolibri is a unique, fun and challenging addition to your fleet!Ĭheck out the flight videos, there is some serious action going on! I think its better to learn handling, throttle control and most important stall caracteristics on a standard plane first. If you fly this as your first airplane, you will need to learn completely new if you then go to a normal plane. You need to control your throttle in the right way, and thats pretty hard for new pilots. Its too different from your normal airplane. If you use dual rates and expo, you could fix this issue, and it would be pretty easy to fly, but that doesnt make it a good trainer (in my opinion). On the other hand, it comes with an extreame roll rate. It flies pretty stable, doesnt stall, and is durable, all things that are good for beginner airplanes. With a bit of practice, you can land in your hand! The best way to take it off is to place it vertically in the ground and launch it like a rocket. ![]() To get the full performance out of it, your elevons should have a throw of 45+ degrees. Then find the sweet spot for your throttle while still holding full up-elevator. If you want to go into the high alpha mode, pull full up-elevator and then punch the throttle untill its at the angle you want. Its like a delta nutball, but a little different.īecause of the canards, it doesnt like inverted too much. Dont lower your rates or throw, you need it in high alpha flight, but dual rates could help. This thing flyes like your normal delta, but because of its narrow wings, it rolls extreamely quickly, you may want to use a lot of expo. The new version has a different wing shape and canards, but flies almost the same.ĬG: 22cm from leading edge of the main wing Its super rigid and the prop is well protected. So I went with a top mounted pusher setup, which looks wierd, but works. Im also not the biggest fan of prop-in-slot because of the weak structure. Because deltas have a CG that is extreamely far in the front, a tail motor was not possible for me. I took that Idea and modified it a little. The original Idea for this came from Forum member Vimana89, who wanted to make a delta airplane with extreme wing sweep. Are you looking for a fun airplane that really stands out from the crowd?
