    Tiger-Motors U8 + 28x9,2 props

    Seems to be moving at a good speed for a MR of that size. What's the added weight of the turbine/fuel?

    New!! Tilt Drone

    yeah, that would allow for more agility than their design; use 2 servo motors and it could spin on a dime.

    New!! Tilt Drone

    I watched a youtube video of some EU racers that claim tilting all 4 rotors caused spin-outs in tight-radius turns. I'm assuming they've taken that into account. And also it was mentioned in the vid that making the front arms a little shorter than the back improved maneuverability as well.

    Oh great... is this true? (registration)

    And you went there... trying to inject logic into a bureaucratic quagmire? That's like trying to give an IV to Superman.

    Old Man.... Agreed. I just get disgusted quite often as I watch "the feds" destroy our Freedoms.

    The FAA needs to go crawl back in the hole it slithered from and someone put a huge rock over it.

    11 Problems with the new FAA Mandatory Drone Registration

    This article was linked (different site hosting it) in another thread, but this will make it easier for people to see. It was buried in post #58 in this thread. Some good thoughts in the article and in subsequent posts in the thread.

    Yep, the tired, old adage of "if you're not doing anything wrong, what's the problem with [insert civil rights violation here]".

    The barometer dongle for Alt restriction would kill most in my area. Part of a property I could fly on has an elevation change of over 600ft. there would need to be some sort of AGL measurement to set the hard ceiling in a system such as this.

    A lot of users are going to need a 12-step program I bet if they intend to remain "legal" in the eyes of Big Nanny. I still say the stroke of a pen cannot make illegal something that was heretofore legal. Wouldn't Ex Post Facto come into play? Ex post facto laws are expressly forbidden by the...

    Carapau, I'll have to disagree with you there. My take on Congress Critters, et al is that they pay superficial lip-service to their constituents, but when the chips are down it's all about what they can do to increase their power and control. There is no accountability. The last election proved...

    YEAIR - Combustion Engined QuadroCopter

    About 20yrs ago when I was in college (read: naive and 10ft tall) I toyed with the idea of teaching weed eaters to fly. Inspired by the Viper TV series and an article in Model Airplane about a vtol plane I set to work. Worked up 3D CAD drawings for a twin ducted-prop craft using control surfaces...

    FPV control via 3g/4g cellular connection

    I've often wondered how well the 'return home' feature works if you've managed to fly around/behind a higher ground elevation. Does it just fly a vector back to base? That scenario could result in an unintended crash.

    FPV control via 3g/4g cellular connection

    I was toying (ha ha) with the idea (work-related) for when I become more proficient and step up to a fuel-powered quad, but my current level of flight experience is novice. I have a prototype bi-rotor I built during my college days that I never put the finishing details on, but cellular tech...

    Seeking opinions on first FPV 'toy' copter

    I've been reading reviews, checking specs, and watching youtube for the last 3wks and have been waffling between the Hubsan 107D and the JJRC H11D. I'm almost sold by the hype, what little info I found so far, on the JJRC offering. Does anyone know of any glaring issues with the H11D? It's...

    Very cheap FPV drones. Fake?. Good?

    I'm thinking for a "toy" I'm going to try the Syma wifi in blue. I'll definitely hit the classifieds when/if i decide to step up the game. Most of the 'larger' units won't be good for flying around inside, but will stand up better to mother nature. I agree with the additional items adding up. I...

    Very cheap FPV drones. Fake?. Good?

    Can't argue those points. Just don't want to offload $300+ and find out it doesn't meet my expectations. Made that mistake several times before with cars. I expect a sub-$100 toy to be just that, a toy. Something to learn on and get a taste of how things operate. I've read the real multi's are a...

    Very cheap FPV drones. Fake?. Good?

    Yeah, I was reading some of the reviews and I think if I get this particular model, it'll be via Amazon. 2x the $, but easy returns if it screws up. I have grand ideas of what I expect of FPV from a real multirotor system based on the youtube vids I've seen. The Hubsan (or if anyone recommends...

    Very cheap FPV drones. Fake?. Good?

    Down to $69 until Oct 10th. I want to get one to start learning and then upgrade to a 250 or larger frame for FPV recreation; no racing that I foresee though. Is the banggood seller reputable?
