Can you operate / test the ESC using a WattMeter (i.e. LiPo-ESC-Motor with No Prop)? I have occasionally found the 'range' available on these meters allows otherwise recalcitrant ESC to operate!

A (8 year old) 'Century Evolution 180 SE' electric heli has been passed around various club members and is now in my hands for 'evaluation' = (sorting-out!). It is in perfect, undamaged condition as far as I can see. (From a deceased flier who, alas, had never got around to fly it by the looks of things). Searching the web I note it is a 'badged' Walkera product. It comes with a dedicated 2.4 Tx (Walkera WK-2403). First off, the manual is poor and written in Chingleese. The (conventional) bind process as described in the manual i.e. Tx on then connect Rx battery, does not work. However, the unusual procedure of connect Rx LiPo first then switch on, whilst simultaneously HOLDING a right stick full left or right input, sets the bind process in process and after a few seconds a successful bind IS achieved. I puzzled over this and thought, are you sure that's correct?!? But now numerous binds later, it is! I've achieved 1 - 2 min flights in the confines of the garden with the occasional very light breeze. With a fully charged LiPo, initial hops are fair to OK though control response is marginal particularly in pitch(elevator), it being reluctant to fly forward with full right stick 'down' input. (Mode 2 Throttle / Rudder Left set-up). OK I am a novice heli pilot and I dare say this is an old/less accurate model compared with current more sophisticated types. Are there any heli pilots who have owned/flown this model? Can shed some light on potential trimming improvements? Pilots notes? The Tx seems restricted in that servo travel is either 100% or 50% and no sub trim to increase throws either. Thanks for any assistance.

IF it's just the (weak) plastic 'axle' pin that's broken, (as mine has done a few times!), then it's a simple matter to insert a suitable size diameter dowel/wire. Then, 'Robert's Your Uncle', no need to shell out circa £15-00 for a pretty plastic bagged replacement.

Having attended two workshops at different locations/host clubs, I agree with all previous. They are very well organised, (even had the perfect flying weather delivered!). Interesting spread of mostly 'mature' (old boys) present. As can be expected from such a diverse mix, some are pedants others more laissez-faire though still in keeping with the spirit of the 'A' & 'B' tests. Having been a member of half-dozen or more clubs across the UK down the years and observing flying standards, I doubt the average club flyer regularly executes the manoeuvres as precisely as some at the workshops demand!

As Frank says, this is a fantastic system. Going to a model show or music festival this year and parking your car in a field of dozens of rows and full of hundreds of vehicles?!!! No problem finding it with What3Words. Just store your (vehicle) location as a favourite and enter directions to when you are ready to depart. It can be set up for car or foot navigation too, so handy for finding that elusive backstreet model shop, (are there any left?), when visiting a new town. The 'app' is available from the usual source on your mobile smart phone. It also gives live traffic updates showing potential delays/hold ups and will offer alternate routes, all with ETAs for you destination. Brilliant!

Any Blade Nano S2 users? If so, any points to look out for during set up and recommendations for set up? I'm binding to a Spectrum DX6i. (There doesn't seem to be much in the way of video or threads I could find from owners, just the usual PR stuff from Horizon!) Edited By Capt Kremen on 31/03/2019 18:39:52

Knowing folk have 'dates-in-the-diary' yonks ahead, thoughts are already being had for next winter's club indoor nights. My club has already enjoyed presntations from George (4-Max) and Andy (BMFA). Located in the southern area (Basingstoke, Chichester, Winchester, Alton), can folk suggest good (none too niche & specialist), guests that would appeal to a wide mostly seniors audience of fixed wing electric & Increasingly fewer i/c fliers?
-
Yep, 'SuperNova' - Red G/F fuz and built up wings with two wire joiners, all-moving tailplane. Very good flat-field flier and off the slope too.
-
Ah .... the Trueline 'Corsair' .... so simple a layout but a superb kit, lovely clear printed plan, (still have that!), a fantastic sports flyer even on 27 Meg 'Brown', Futaba 'M' & 17M(?) Black & Red servos (different direction - no servo reversing on yer trannie back then!)

Gyro Training Buddybox Transfer
Capt Kremen replied to Capt Kremen's topic in General Radio Discussion
Thanks Allan. Yes we, (club instructors), found the 'Apprentice' less than satisfactory with its A3X(?) super dooper stabilisation, not to mention the model itself which wobbled around & across our grass strip on its spindly u/c! Maybe just stick to just de-selecting controls that the student needs to handle until they've got the hang of 'pole stirring' ... and just how much/little input may be required. -
I have dabbled with various makes of gyro, to greater or lesser success, using a variety of models & two major brands of R/C gear. (See latest RCM&E article if unfamiliar with such devices). As a club instructor, I have to date not installed a gyro in any of the training airframes used. However, the recent magazine article rekindled a possible interest and wonder the following. If a training airframe, operating satisfactorily with a gyro switched 'on' using the 'Master/Instructor' Tx by the instructor, then transfers control to the 'Pupil/Slave' Tx, does the gyro operation transfer (satisfactorily) with it? Of the several gyro systems used, some, (if not most?) have the ability to be switched on/off and often into other modes of operation such as heading hold. However, Basic, (in terms of control function), Tx that might be used for the 'Pupil/Buddybox' Tx, may only have 4 controls i.e. Rudder, Elevator, Aileron (Single or One per aileron) & Throttle. Other controls & functionality may be restricted hence seeking confirmation it would be safe & practical to use a gyro for buddybox training. If there are no issues with 'gyro' buddybox training, the advantages can potentially be many. Flying and exposure of a pupil to livelier weather conditions i.e. switching the gyro in/out so the pupil can learn to cope with a bit of a blow unaided! Flying more advanced types, such as conversion from high wing to possible less stable low wing and so on. Instructors using gyros, your experiences, any aspects to beware of/avoid etc. etc.?

Thanks Ken Compared to your 'original(?) red, white & blue striped' colour scheme, how do you find orientation and general visibility using the 'metal-look' finish? (I only put a (thin) 'metal' strip on my 'Acrowot' to catch the occasional sun-beam we have and glint back i.e when turning finals downwind, as an aid to these ageing eyes!).
-
In the process of redecorating my 'AcroWot' in an alternate colour scheme, I have applied a relatively thin, (2 ins wide) strip of self adhesive metalic silver tape, spanwise along the top of the wing. OK, it's not going to continuously glint at me in our glorious grey overcast skies but maybe now and then, just sufficient to assist distant orientation. However, browsing the web info, I'm having second thoughts as at least one post reports radio issues having applied small quantities of similar metal/holographic tape. Is it worth the possible risk, (assuming there is any)? Is the amount so small as not to affect a correctly orientated, twin aerial 2.4 MPX Rx? The value and observable effect so small as not be worth it anyway? Your valued experience appreciated.

Hopefully, many of you have managed to escape 'The Sound of Music', 'Mary Poppins' & 'Jungle Book' on the box for the x+million time and get out to enjoy a flight or three. I have been that fortunate, though the last few days have been a bit nippy to say the least! What clothing do you die hard winter flying folk find best? (I do appreciate this will be rather subjective & personal choice). I have tried, (with varying degrees of success!), assorted long-john/thermal vests from the likes of 'M&S', 'Mountain Equipment'. Gloves, mittens in full & finger-less style in wool, leather, cycling/running style. (The latter made my hands colder if anything!). Woolly hats various, scarves and neck warmers too. Socks - thermal for the use of etc. etc. So Polar explorers and cold weather model fliers, what's your warmest clobber?

Since the realignment of some channels to other use, have experienced similar 'pixilating' issues And loss of some channels. Rang 'Freeview' and they sent, 'free-of-charge' a couple of signal attenuators to plug between aerial and the TV set aerial socket. Sort of improved things but still missing a few channels and getting some pixelated ones too. Tried to book a TV Aerial engineer via local 'Check-A-Trade', in the absence of personal recommendations/experiences of friends/neighbours. Result = a complete waste of time and several 'cowboys' either failing to turn up or else trying it on i.e. no two gave the same (very dubious) opinions but certainly wanted to charge for it! Pity the poor old lady unable to see through their blather.

I have a balsa/ply 'AcroWot' (Mk2?) fitted with a Hobby King SK3 Aerodrive 4250 500kv brushless motor. After a while 'resting' in my hangar, I'm dusting it down during the hols, in readiness for resuming flights with it. As is often the case, the HK web page for this motor is scant on best prop. (I had previously flown this model on 5S and a cautious 14x6). Having reconfigured the flight battery access to a 'top hatch', I can now easily fit a 6S LiPo. So anyone out there using this motor? If so, with what Cell Number & Prop Combinations or could you run data thru a e-calc programme to suggest best props. I reckon on using 5 and 6 cell LiPo packs. I have a 100A ESC fitted so plenty of headroom to cope with current draw and some in reserve. Thanks for any practical suggestions AND Compliments of the season to all.

'INXS' ....

A fellow club mate is interested in obtaining a HiTec Gyro HG3XA, (He uses HiTec radio equipment). There doesn't seem to be any of these this side of that 'Big Pond' i.e. only HiTec USA, TowerHobbies USA etc. seem to sell them, none showing in Germany e.g. Hollein or Lindinger. I use MPX and to my casual observation, the Hitec Gyro looks the same as the MPX G3 unit that I and other (non MPX) fliers use in my club. So ... Questions: Anyone know of a HiTec HG3XA gyro unit for sale in the UK? Is the MPX G3 gyro the same as the HiTec unit, just a different makers label on the unit? Many thanks.

Whilst up at the strip today, all present took their turns attempting the 'Bunt'/Outside Loop manoeuvre as prescribed for the BMFA 'B' test. All used their own, (well-flown models), a few Wot4s of different vintages, only one (Wot4) succeeded. The majority of models 'snap-rolled' out on the downward portion of the manoeuvre. Now back at 'the hangar', had a look around on line and I was only able to find a few videos/web pages with any details on performing this. Most often they show the outside loop being commence from a roll inverted and then climbing up. OK Ex-spurts out there, what are the prerequisites? Type of model? (Any one layout/type better than another?) Control throw(s) ? C of G location (i.e.fore/aft), Model Power, Control input(s) - When & How Much etc. etc.

Unable to Contact Carbon Copy
Capt Kremen replied to ColdLazerus's topic in R/C Retailers / Distributors / Manufacturers
I can only echo the (poor) customer service experiences of previous posts. I had to repeatedly phone this company and was told 'The goods are in the post ....' de dah de dah de dah! Of course they never were but after continual calls eventually, surprise, surprise the carbon u/c ordered turned up. I don't know what issues this company may be having but I will not be using them again.
