Do you actually GET a copter with servos as shown in the ad copy? Having sampled some Hong Kee wares in the past, I'm not venturing $ to find out.
NOTE: the word "gyro" is absent. No sale.
Come see my HUGE 3-channel Helicopter collection!

check THIS out ....
[only for general info]!
After one week of hard work, eventually requiring me to change MANY essential moving parts .... I finally got my latest (I have kept 3 others in great condition!) new G.T. 5888-B sorted out to fly, handle and sound extremely well.
It is now almost TOO fast to have fun flying in my livingroom! At low rate it is reasonable and acts like "normal" tiny (19 cm rotorspan) 4-ch coax's ... but at high rate I really have to be careful!
Lots of fun, anyway.
I think the factory could not make such a fine-tuned item in mass-prdn: I had to find blades of equal weight, micro-balance the stabilizer bar, move gears microscopically to find low-friction placements, fuss with microscopic tweaks to the aluminum blade-holders, change 2 motors with replacement ones, change all the links, fine-sand to perfectly fit some parts of the plastic pieces sanwiched btwn the alu blade-holders, sand and/or add CA gel and sand the blade-roots to perfectly fit and hold the blades at the angles I wanted, adjust looseness, pitch & coning angles ... and generally have LOTS of perseverence & patience.
But the results are truly amazing. Star, one of my two intelligent birds, understands these helis, and was watching for all thiose days as I tried, tested and imprtoved everything. Unlike male Kiki, who is watchful AND brave, and who will stand his ground unless it's clear something is going to very quickly land on his head, female Star is cowardly enough to wait intil the heli is in my hand before zooming down & closely buzzing it and me!
So when I did FINALLY get everything so well tweaked that it can take off like a rocket and make a sound like a fullsize heli, whistling and thrumming, and making fast very TIGHT turns and instantly hovering ROCK-steady with the sound of an expensive Swiss sewing machine .... Star was SO obviously impressed that she raised her tail and had an appreciative organism (the RCGroups softare won't let me write the actual word).
I do like to see females apreciate my work (OK, human ones very much moreso) ...

Hello everyone. Before I put in my first post I'd have to say I'm just a beginner to the rc heli world - just 2 months ago. In fact this is my 1st post in this (or any) rc forum!
Short answer to killbucket's question is yes, I did get what was on the photo. My HQ852 was bought off ebay (about USD85 incl postage - arrived in just over a wk) as a set with extra 7.4V 900mAh battery, landing kit and 4 extra changes of blades, of which 3 of them were OEM types which needed a bit of scraping and shaping around the mounts to have them fit properly (they're thicker than the standard - and they're supposed to swing about freely). It's a mid size heli at 39.5cm but dwarfs my super stable 9808 which is only abt 1/2 the length. It does have 2 mini servos on each side which contol the left-right rolling movement and the forward/backward movement. These effects can be adjusted like a normal servo system by placing the rods that attach to the servo at the different holes on the lever attached to the servo for different leverage - so further away from the servo for a faster/greater response. These servos have those removable connections to the main all-in-one board which does have a gyro (if the label is to be believed - sorry I'm not an electronic-type person so I'm honestly not sure which component is the gyro). I've owned the 852 for about 3 weeks now, but must say I've been really too busy at work to bring it out too often. Of the 3 times I brought it out it was really fun, though breaking blades on the last 2 late evening flights - to watch the lights. Otherwise it's quite robust noting the heights that my chopper have fallen to the gound (about 15m up). The range is about 40m, maybe 50m max and the power will suddenly be cut off if it does go out of range. This is good enough for me since I like to see the chopper while I'm flying it and learning how to land properly outdoors is still something I'm working out . This chopper is just about easy enough to control outdoors, but in VERY light wind conditions (prob up to 1m/s). Otherwise it will just be carried away until it goes out of range - maybe it's my current skill level, but flying outdoors is much different from flying indoors. Btw, the rods controlling the front back and roll left/right have to be adjusted at the servo levers for flying outdoors otherwise it would just be too weak to fly against the wind. Flying indoors its probably as stable as my 9808 (like a syma s107 i'd imagine - stable enough to land on a book) - but my apartment is really small so it's between the floor to dining table; really too big for my appartment - It would probably be good in an indoor sports hall. Overall I'm quite glad with it since it looks really good just sitting on my floor or shelf - the paintwork is great - a metallic orange. The other things I like about it are the batteries are easily swapped - 10 secs with a slight modification involving a rubber band, and the 4 trims on the controller unit actually work as they should! I also like the 'big wind' it creates which blows envelopes, newspapers, etc off the table when indoors. The way I'm going with it I'll be blessed to get past Christmas without bending the shaft or running out of blades on the flights outdoors - it's windy this season - and my skill needs some improvement Worth the money? Yes for me for a beginner's 4-Ch. Oh yes, take note that there are 2 types of controller units and some of those like me that fly a mini 3-channel in the house would need a type 2 contoller with the throttle and roll-left/right on the LHS, while the forward/backward and turning/rotating left/right on the RHS. I didn't know this when I purchased but I think they ship the type 2 by default.
