Thread: Modern domestic heating thermostats
27/10/2020 22:21:29

I recently had a new Bosch/Worcester boiler fitted with a wireless programmer/thermostat. Right from the start, the boiler seemed to have a mind of its own, not following the thermostat commands. Chatting to my neighbour, she said her boiler had started playing up, exhibiting the same problem. She had the same system as mine, installed by the same plumber.

Whilst reading the programmer instruction booklet for the umpteenth time, the penny dropped!!!

The programmer interface box has switches on the back panel for setting the wireless channel. Comparing the two, both our systems had been set to the same default channel, so we were controlling each others boilers!!!

I changed the channel setting on mine - problem solved!!

Thread: Plane but which ?

The original 72" Astro Hog has an upright engine and would suit your Saito 62.

Plans can be downloaded from Outerzone HERE or printed versions are available on ebay.

Hats off to you, that works a treat !!

Thread: Replacing start capacitor for compressor - help please
02/10/2020 20:46:06

I'm not very good with colours, but it looks like red, violet, orange to me. In which case it would be 27k ??

02/10/2020 16:29:11

Hi, The relevant values are 56uF and 250V, So most Motor Start capacitors near this valus will be OK.

Something like this :LINK

You will have to transfer the resistor from the old one, check it with an ohmeter to make sure it is not open circuit

Hi David,

Also unable to view any of the digital issues. Running windows 10 and Google browser.

I get the following -

An Error Has Occurred

I'm sorry but we can't process your request at this time (bad referrer).

Thread: Spektrum Tx and Rx compatability, or binding trouble
19/09/2020 08:47:37

See here - DX6E

19/09/2020 08:43:09

Hi Chris,

Your AR6110 is a DSM2 receiver. The manual for the Spektrum DX6e claims that transmitter is both DSMX and DSM2 compatible so, according to Spektrum's literature, you should be able to bind the AR6110 with the DX6e.

Have a re-read of the binding procedure to make sure you are following it precisely - good luck.

Thread: Cheap or good Quality Lipos ???
23/07/2020 16:19:39

Gens Ace LiPos have given me good service (I think I bought them from Giant Cod back in the day!) . Most are now over 5 years old and still performing well.

Thread: Spektrum DX8 G2 Weight?
17/07/2020 21:19:22

Many thanks Cuban8, that's useful information. I'm thinking of upgrading my aging DX8, mainly for the telemetery and considering the DX8 G2 but weight of the controller is a consideration for me..

17/07/2020 15:12:37

Can any one tell me the weight of a Spektrum DX8 G2 transmitter?

I have downloaded and searched the user manual, but can't find any mention of how much it weighs (it must be a lady!)

Perhaps a kind owner can pop theirs on the scales for me?

Thanks.

Thread: Maricardo Plan MAG 1529
10/05/2020 09:06:00

The Maricardo build is progressing (slowly). I'm just about to fit the firewall. I notice the plan now shows no down or side thrust.

Should I be incorporating a couple of degrees of side thrust, perhaps those who have gone before can comment?

It will an electric set up, I was planning to use an SK4250-650KV with a 4S 4000mA battery, ex my SLEC Funfly, which I reckon will be adequate for my style of flying. (4Max's website suggests a more powerful/heavier set up - a PO-5055-595KV with a 5S 4500mA battery).

Any comments appreciated.

That's a very tidy looking model DaveB. I might well 'borrow' that colour scheme .

I'll probably go electric as well. I have a spare motor from a SLEC Funfly that was demolished in a mid- flight coming together.

I had a promo email. Not sure if it is still valid, but the promo code was LASER40

Give it a try, here's the link 'LASER40'

27/02/2020 13:26:07

Thanks for your reply kc.

Looks like the 2004 free plan has not been fully 'Strawsonised' as the main wing still has a slight dihedral and the ailerons are 1"x1/4" instead of 1 1/2" x 3/8". As Sarik are offering 40% off the laser cut kit at the moment I succumbed. Any way, it will pass the time whilst the water is drained from our flying site at Shrewsbury.

26/02/2020 22:41:51

I'm thinking of building a Maricardo.

Can anyone tell me if the MAG 1529 plan currently available from SARIK incorporates the Paul Strawson modifications viz:

Zero Dihedral, bolt on wing and wider ailerons and rudder etc.

I have the original April 2004 RCME plan, which doesn't have the above mods. So I'm wondering if the plan has been updated during the 16 years it has taken to rise to the top of my build list!!!

Thanks, Sparks

Thread: Hitec servo.

The screw size for a Hitec 645MG is M2.6 x 8mm - Google is your friend!

Hi David,

A dab of threadlock, such as Loctite, on the nuts is a useful precaution.

Tim,

To quote Martin from an earlier post, 'Flown correctly, for an instant during the turns between the circles, the model should be flying directly away from you'.

Thread: Variable resistors
18/04/2019 19:20:41

Here is a zero-cost solution using the existing 5 Ohm pot.

If its a three terminal pot, connect the two outer terminals together and connect to voltage input.

Then take the output from the middle (wiper) terminal. For a 5 ohm pot, this will give you a 0>1.25>0 Ohm pot.

e.g. at beginning and and end of pot travel, resistance will be 0 Ohm. At mid-span resistance will 1.25 Ohm.

You could restrict pot movement to half scale mechanically to give 0>1.25 Ohm span. The travel/resistance will be a little non-linear, but shouldn't be a problem in this application.

Hope that helps, Sparks
