![]() ![]() Just like a few years ago when I built two identical (but for engine) planes, one 72 four stroke, expensive OS, the other 52 two stroke, cheap SC, to see the difference. SOME models were/are available as two types, Nazgul Evoque is one such, and I had intended to try both, because I could. About the only truly observable result of the design differences is the dead cat avoiding props in sight, and even some of them still have prop tips visible. I have all sorts, true x, narrow x, wide x, stretched length, dead cat. So I guess all my rambling comes down to, should I just go squished and work it out with PIDS and filtering, or can dead cat make a difference in that aspect and result in me doing less tuning? Side note, whichever I go with, it's literally only two M3 screws per arm to change positions in order to switch arm configs, so don't feel like your opinion or suggestion could result in me buying a $100 frame I'm not happy with.lol. It flew well enough, but it felt really floaty, and not aggressive enough for chasing motorcycles n stuff. I flew a friend of mines 6" a little while back with squished config, same size motors and exact same Gemfam props I'll be using, and his tune is similar to mine. I know a lot of people say you can't really tell the difference between a dead cat and stretch x, as far as flight characteristics, which may be true, and I'll be carrying a Hero8, and definitely don't want any props in frame. So my decision is between squished or dead cat. Didn't realize this until I received it, and was planning on building it squished as is pictured on GetFPV where I got it. Croc HD, in which you can alter a couple mounting screw locations to choose between dead cat, squished or stretch x, and hybrid. Great explanations, was curious, I'm building my first 6", to use as a chase quad for motocross and downhill skateboarding events. The Dead Cat frame came about purely to keep the props out of view of the camera and (2, 11:33 PM)SnowLeopardFPV Wrote: A Stretched-X frame is meant to be better for speed and racing while a Squashed-X (aka Compressed-X aka Wide-X) is meant to be better for freestyle, but it's all subjective depending on who you ask. The frame is the base, it has importance, but its for tiny differences, aslong as its not faulty as example about stiffness.Įdit: watched snows link, whats described as "hx" seems to be the most rigid geometry by shorter arms, like an "H" frame. ![]() ![]() The plus frame configurations is farawy the best xDįlight characteristics are more determinated by the propchoice, battery choice, the uaw. Widewingspan = (less "unclean air" some tell its not important) less performance, more easy handling on high speedįrom hardware configuration and tune we can get different very results, dont mention on it as the most important part until you get into "perfect tuning" and are able to reach the limit of performance of your build by pilot skillsĪvarage pilots which describe one configuration as the best and so much better for their need are "hyping guys" it needs very high pilot skills to speak about these differences and benefits.Īll configurations can provide huge pleasure :-) There was also a configuration where the wingspan of the fron and back where different for racing, but i guess it was just a missunderstanding about it and some pilots fly faster on a slower quad xD cant handle the performance. Overall its not that wide or streched x have to be more stable on one axies, its also the tune and tunability which determinate the whole performance - its just the possible direction.Īnother thing to mention is a small wingspan (true-x) which can provide the best performance is more difficult to tune, there is a more "precise" tune needed to get truly better performance. on a high speed stability can make a difference, therefor "streched"-x does give more stability on the pitch axie.Ī wide-x does provide more stability on the roll axies, prefered to get (stable-)smooth rolls. yaw performance is the most difficult quest a quad have, where we struggle to improve the performance.Ī true-x where the rotors have a few millimeter distance between (can) have the best yaw performance, the most agile settup. a wide wingspan gives a more stable flightcharacteristics but it get a low yaw performance. A general difference is the wingspan and the space between props. ![]()
