Thread: Lipo advice
21/02/2019 12:14:53

As long as the C rating multiplied by the ampere hour capacity of the battery comfortably exceeds the current rating of the ESC/motor then you should be OK

For example I use Turnigy Graphene batteries, a 3s 2200 65c gives me 5 minutes flying, a 3s 3000 15c gives me 7 minutes pulling a max of around 25 amps. They both end up approximately the same temperature at the end (barely warm) and are both the same size/weight. However if I was to try to fly something requiring more than 45 amps the 2200 battery would be fine, the 3000 probably not so good.

Regarding chargers, don't forget to decide whether you want a mains or low voltage charger run off separate mains power supply or car battery or one that will run off either power supply.

I use this **LINK** and it has been very good.

Yes we were made of sterner and oilier stuff and spoke loudly so we could be heard above the noise of a 2 stroke 60 with a venturi exhaust 😳

Not sure if this is OTT optimism or a bad case of fat fingers when setting up the advert.

Thread: FHSS flavours

I thought that might be the case, never mind.

Thanks for the quick reply.

I purchased at pocket money prices an Axion Excell 200 micro helicopter which was great to learn on. I also purchased an Axion Polykarpov for indoor/calm outdoor use again for peanuts. The transmitter for both is an Axion AX-4CT which says it uses FHSS technology.

Now the question is are all flavours of FHSS the same? Will the Axion transmitter work with other manufacturers' FHSS receivers?

Thanks

Best heating option for hobby shed? Large single malt, but don't expect what you build to fly straight!

Thread: CDI interference?
09/12/2018 16:35:16
Does the CDI unit have any form of interference suppression built in, could it be failing after a few minutes use and then reverting to normal operation when the engine is turned off? From experience with car CDI units they put out a lot of voltage and produce a fat spark but can also produce a lot of radio interference.

I presume SLA means sealed lead acid battery.
Thread: Aerostar 40 amp speed controller
18/11/2018 19:36:27
Bought a slowpoke in the hobbyking sale, it went together OK despite the instructions 🤔
Bound OK to a spektrum transmitter /receiver but when you throttle up the first thing that happens is that the motor pulses, increase the throttle a bit more and the motor idles steadily and increasing the throttle more gives progressively more power. Can anyone tell me why the motor pulses with the first increase in throttle?

I've just received a BT Black Friday offer for a Superfast Fibre Upgrade Free with Free Smart Hub. We live in an apartment & as far as I know there is no fibre connection to our building. BT did dig a trench across our car park entrance last year & connected the next building along the road, Any one know how difficult or expensive to get fibre into our building. There are 45 apartments.?

AFAIK BT's fibre offering is FTTC (fibre to the cabinet) not FTTP (fibre to the premises) so the fibre cable goes to the green box somewhere close to the house (in my case about 100 yards away) and the last leg is completed on the legacy copper phone wire. If you live close to the cabinet you can get good speeds without the need to lay a fibre into the apartment. In my case I get 50 Mb/sec down and 12 Mb/sec up consistently

I have been with BT for some time with, so far (kiss of death alert!), no issues. I use Firefox and Yahoo mail on BT's 50 Mb/sec FTTC and have not seen a problem. I actually get 51 Mb/sec down and 12 Mb/sec up which is fine for my needs.

A year or so ago BT had an offer on which was cheaper than I was paying at the time so I called them up and said if they gave me the deal I would sign up for another contract period as the previous one had expired. They were happy to do so, when this contract expires I will do the same again.

The other advantage of using BT is that there is no argument between BT and the ISP about where the source of any problems lie, if there is a problem it's down to BT to fix as it's all their system.

Thread: lipo battery charger
14/11/2018 13:56:47
I started with a cheap hobbyking accucell s60 charger, it still works ok but the fan became a bit noisy so I bought a JP Radiant duplex II from Steve Webb, very versatile and seems well made.

We had a similar problem in our previous house.
It was sorted when the police removed the body that the previous owner had covered with the patio.

Actually John it's not that uncommon. I used to clean the tip of an iron by flicking my fingertip over it (it was just a learned knack).

Anyone who has used soldering irons on a daily basis can do that - the trick is in knowing HOW to do it

Alternatively, see the quote from the film "Lawrence of Arabia" below

Potter: [trying to copy Lawrence's snuffing a match with his fingers] Oooh! It damn well hurts.
Lawrence: Certainly it hurts.
Potter: Well, what's the trick then?
Lawrence: The trick, William Potter, is not minding that it hurts.

. ,. the rudder had been enlarged at the trailing edge, any idea why this might be?

Two possible reasons: maybe to increase the rudder response or to help damp down the dutch roll tendency.

Trevor

I did wonder if it was to do with Dutch Roll when you mentioned it Trevor.

Is Dutch roll a bit like a French stick but with Edam instead of Brie?smile p

Thanks Trevor, the one I have has just a little hanger rash and I replaced the servos as they looked a little tired, also the rudder had been enlarged at the trailing edge, any idea why this might be?

I also have a 1975 Graupner Cumulus, but I am not going to risk that without some experience.

I have picked up one of these in good condition very cheaply, there's not much info on the web but the little there is indicates it's not very good, does anyone have any experience/tips to pass on before I throw it off a slope?

Just checked and it looks like the Lightning doesn't have flaps so you won't be able to use a crow set up but can, as you said, use the ailerons as spoilerons.
