I think you may be confusing the "-840w" in the motor name as indicating that it will produce 840 watts. That's not the case. The spec of the motor is working range 10 - 26 amps on 3 or 4s batteries, ie about 120 - 420 watts, with a max of 37 amps for 15 seconds @ about 600 watts. 300 watts sounds about right for the Funcub. Mine is absolutely stock with recommended motor and the CG is spot on with no adjustments or ballast. In fact I have 8 Multiplex foam models, some over 7 years old, and all are completely standard, the designers & developers know what they are doing.

Well, digital back issues are available to me this morning! Thanks to whoever pulled the strings, or perhaps it was just coincidence? And Pocketmags works on the Ipad but not the website, but that bit does not matter to me. -
Posted by gangster on 11/02/2015 08:47:59: . I also spoke to a guy the other day who paid £160 for a bulb change on a Lexus I could believe it. My Lexus required bumper &/or wheel arch liner removal. But in fairness to Lexus my Main Dealer replaced the blown bulb as part of a fixed price service (£210ish) at no extra cost.

Been there done that.........

I also upgraded from print only to print + digital 2 weeks ago and received written & email confirmations. However I still cannot access the digital back issues or Pocketmags. My first email query was responded with an unhelpful copy & paste standard reply, the second has not been responded to. Very poor service.

Depend on the type of charger are you using. If it's a trickle charger then you can use it without any problems. If it's a fast charger calibrated for NiCds then the peak detection feature may not work on NiMh's. Some do some don't. There is a 'softer' peak on NiMh's compared to NiCd's that some chargers will not detect. If you try it and keep an eye on the cell the charger should cut off soon after the cell gets warm.

Flying height restrictions for planes under 7kg
John Lee replied to Simon Hall 2's topic in Electric Flight for Beginners
Posted by Biggles' Elder Brother - Moderator on 28/01/2015 19:55:16: Charts showing controlled air space in the UK are available online here That link will take you to the chart centred on Woodvale near Southport. You can zoom out using the bar at the bottom left, slide the map and zoom in to anywhere you want. It just like using Google Maps or Google Earth. A quick look will tell you that the vast majority of England is indeed in controlled airspace of one sort or another. Well, yes & no. A more detailed look will show that the vast majority of that controlled airspace starts at a considerable height, which is of no relevance to us. Controlled airspace at surface level (marked as SFC and looking like a denominator in a fraction on the chart) is comparatively rare & mainly confined to areas around major airports to protect public transport flights on approach and climb out. I suggest a proper Low Level Aeronautical Chart is a better/easier way of checking the area you are interested in. -
Flying height restrictions for planes under 7kg
John Lee replied to Simon Hall 2's topic in Electric Flight for Beginners
Posted by Simon Hall 2 on 28/01/2015 15:56:22: Dave, apart from airport ATZ, what else is controlled airspace and how can I find this out for my area? You need to consult a "Low level Aeronautical Chart". The easiest source is usually a full size pilot in your club, or a flying club at your local airport. Flying clubs (full size) invariably have one pinned on the briefing room wall and should help you interpret it. -
Either. Y lead - one less connection, one less channel 2 channels - Can trim individual servos. Can set up differential. Most modern radios have a dedicated set up for using 2 channels in the Tx menu.

Chucking it off a hill is probably the best thing for it. I had one in the 80's in the Yellowjacks colours with a 60 & tuned pipe at the front. I never managed to get it more than a couple of feet into the air as it roared off into the distance at Jurby airfield. It was very twitchy so give it plenty of expo - that wasn't available in those days of course. I sold mine on with plenty of caveats. Good luck!!

The distance between centres on my calliper gauge of the back plate screws on my engines are: OS 46FX and 55AX 27.8mm OS46AX 26.8mm Afraid I no longer have a 46SF to measure, they were replaced by FX or AX's and would confirm what Bob said - they are drop in replacements on beam mounts.

Took the opportunity this morning to exploit last night's snowfall.

Saw the full size at the Paris Airshow in the 70's where a wag commented that it didn't need to use pesticide, it just made a low pass & the bugs died laughing at it....... Edited By John Lee on 16/12/2014 16:23:52

'Ares' Tiger Moth 75
John Lee replied to Paul Holmes 2's topic in Indoor Models, Ultra Micros and Small Park Flyers
Paul I've not had any trouble with mine over a season's flying , it's a bit of a mystery as there does not seem to be any way to make any adjustments. I can only suggest rebooting the transmitter by removing the batteries, waiting a bit then start again with a fresh rebind. Failing that maybe ask the distributor J Perkins? Percy - the Ares Tiggy is a micro model with a dedicated basic mini Tx & built in block Rx/servo/ESC. -
Each to his own but having used a Hitec H4 multi charger for the last year I'm delighted with its capability and convenience. Using a 600w power supply it charges four high capacity 4s & 6s packs simultaneously without a murmur. Not cheap but a quality piece of kit. It was reviewed in the Aug 2013 edition of RCM&E.

Motorcycle transportable model
John Lee replied to Eifion Herbert's topic in All Things Model Flying
Multiple Xeno fits the bill. Folds in half and fits in a dedicated transport bag. You also have the option of electric flight. I bought one when they first came out as it was ideal to fit in the small boot of my MX5 and its still going strong. Flys nice too. -
Had the same problem in a Hangar 9 Toledo Special. Changed the H9 supplied spinner to an aluminum one, problem solved.

Well, I bought a Solius and having flown it a bit now agree 100% with Steve's assessment, thanks Steve. Packing in all the radio was a bit of a problem as I wanted to fit the new Spektrum vario which meant finding room for the TM1000 telemetry module. I placed the module immediately behind the motor, the sensor in the motor lead 'tunnel' and then used a carbon Rx to get the aerials away from all the electronic gubbins. The vario compliments the model really well. Used with a Dx9, the audio output is switchable and is silent in still air, gives a low tone in sink and a rising 'beep' in lift. It also has an altimeter function as standard. Thumbs up to both pieces of kit.

Does your club allow members to fly by themselves?
John Lee replied to David Ashby - Moderator's topic in Model Flying Polls
Posted by Martin Harris on 16/07/2014 14:29:23: More seriously, we don't encourage lone flying but let members use their judgement - there is an enhanced risk of course....... It's not an enhanced risk to fly alone - it's a different risk. Flying alone you don't have the risk of being distracted, of being hit by another model/loose prop, of having a mid air, of someone walking in front of you when you are landing.....etc etc. -
Hobbyking delivery
John Lee replied to Spice Cat's topic in R/C Retailers / Distributors / Manufacturers
My last order was 2nd June, just $12 worth, it was delivered yesterday, postmarked 6 June in Malayasia. -
Back in the 80's 'Carrier Deck' was quite a popular club fun fly event, devised by Mick Reeves. You had to fly the model as fast as possible between two markers and then as slow as possible, points were awarded for the speed differential. Then you attempted to make an arrested landing for bonus points. The arrested landing part was not easy. However if you want to give it a go the line itself was bright orange thick fishing line, it was supported off the ground by bits of expanded polystyrine about 3 inches square with a slot cut half way in which the line sat. At both ends of the line were small cloth bags filled with sand. Fully portable & easily set up.

In the early days of Lipo's I had a small (about 10Mah) 1 cell blow up on me when I assumed another manufacturer's charger with the same connector would be suitable. Made enough of an impression on me to fully focus the mind every time I've charged a battery since.
