Been looking for a small quad brushless quad for a while more power than a tiny whoop with proper brushless motors something like 2s power but still small and safe enough I feel happy flying it inside and around people.
There used to be a nice quiet area near the old office where I could get some flight time in but it's now pretty far away and also on the property of another company. So I've been keeping a look out. \
A while back I did get a small brushless quad which came in kit form but so far will not fly and I'm not sure why the rotors spin in the right directions I can feel it shifting air and it's gyros seems to be leveling it correctly but even at full power it just won't fly it just sort of skitters on the ground. So wary of buying another useless kit I was looking at some of the premades that have started popping up. The eachine lizard 95 first caught my eye very favourable reviews looked powerful but seemed a little too powerful a 3s even up to 4s machine.
Then I spotted the Revenger 55 also from eachine which is a tiny little brushless quad with 2s setup and integrated camera beta flight compatible f3 flight controller and with built in prop guards. This seemed ideal and it was also 120 bucks so I ordered one in DSM2/X bind to fly.
A week or so later it arrived in a small box from banggood.com.
It's an absolutely tiny little thing 55mm diagonal and basically fits in the palm of your hand I think it might be smaller than the first brushed quad I got the venerable hubsan x4. It has these micro sized 1102 11500KV brushless motors which use 4 bladed 1535 props (35mm diameter I think) The esc's (unknown amperage but with relatively new features like DSHOT600), flight controller (teeny F3), and receiver module all come in this small stack of boards in the center. Glued to the side of the frame is a small camera and a small 25mW vtx. There is also a buzzer on the back and I think it supports some telemetry for tx's that support it (mine doesn't). It comes fully assembled with BetaFlight 3.1 loaded and configured with a 2s 400mah supposedly 40C battery and a set of spare props some sticky velcro for attaching the battery even some tiny allen keys and screw drivers a fairly good manual and weighs in at 46g without the battery.
I loaded up the configurator and set the thing up did the radio bind then couldn't get the thing to arm remembered the fact my crappy radio is out of range so had to remap the rxranges so it registered idle throttle correctly and then I was off. Keep meaning to get a better radio now there is the newer cheaper tiranis qx7 and things like the turnigy evolution I might look at investing in one but of course that would mean needing all new rx units.
Not flown it much so far was just about getting the hang when the battery ran out. Found it has a lost buzzer mode which is mapped to a channel I forgot to configure so it was bleeping all the time. It slings the battery underneath and that makes it not stand up level very easily which made take off tricky. Once in the air this adds a fair amount of natural stability but it means it could do with some sort of landing gear or launch platform to allow it to get off the ground and out of ground effect from a level. Flys really well and so far seems pretty resilient I had it in angle mode by mistake so was crashing the thing constantly and so far the propguards keep the little blades intact.
It's amazing how far things have come that for a relatively low price I can get this tiny little brushless quad with a lot of power that fits in the palm of my hand and it almost out of the box flyable.
Need to get some more 2s batteries for it but think it's a good little machine for getting some quad time in where ever.
