|Thread: Where are the retailers now|
There's a list here.
|Thread: AAIB Operation Of Drones|
Didn't the police in Merseyside a few years ago have to stop using them because they didn't have a suitable license.
I agree by the same reckoning it's OK for Estate Agents to use drones to photo houses and Farmers to check their fields etc, providing they are not being paid specifically to do this work. They have opened up a can of worms here as to what defines recreational flying.
|Thread: Can I use 3rd-party temperature sensors with FrSky smart port sensor?|
Allan, have you seen the OpenXsensor projects, using Arduino boards to talk to the smart port, you'd have to configure it with your thermistors but you should be able to get it to work.
I've built a few Varios for use with the Multiplex M Link system and they work well.
|Thread: Check on power calculation|
If it is way overpowered then one other thing you could try is to go to a 2S lipo, this will drop the Wide Open Throttle rpm and the power (on the same prop) and hence the max amps too. I did this on a Ripmax Fokker D7 which was way overpowered on a 4s setup and flies lovely (using the same prop) on a 3s lipo.
As BEB says the main governing factors are prop, motor Kv and voltage, if you want to get an idea of the performance and adequacy of various set ups then there are on-line programs which can help you like ECalc and Drivecalc .
|Thread: Any advice on comparing plans from different designers|
John, just a thought, Traplet usually have a tent at several shows and take a good selection of plans with them, I know they are at Wings and Wheels this weekend, if you are going to this show if you e-mail them they might be able to take both plans to the show for you to decide.
BTW just reading JS's comments above, a lot of these plans are from before when CAD etc was around so you may find things like interlocking tabs were not even considered. We've built some models from plans I bought 30 years ago, they did go together quite well and flew really nice, changes we made was to do things like have separate aileron servos rather than one central one and a bell crank in the wing. Also bear in mind that the structure on full size aircraft had to make allowances for fuel tanks and ordnance not something the model designer has to consider!
So had my E Flite DH Beaver, but they were moulded in to allow a standard Y lead to be used.
|Thread: Horizon Hobbies|
Yes but sometimes returning it you will end up with a new one FOC.
|Thread: Alternative to Spektrum|
If you use (or would like too) a vario in your gliders then research the Hitec Aurora a bit further, my friend ended up buying a stand alone vario at great expense. I'll 2nd Percy and if you want a simple to program, but still quite poweful system, the new MPX Cockpit Sx is worth a look, another friend has one and it's very nice (if I didn't already have a Royal Pro to go with my Profi I'd get one).
But if you are a happy Spekrum user why change, give it a few months and see if the product support issues sort themselves out.
A few years ago, I set up a small EDF with flaps and retracts on a Dx6i. Y lead on the ailerons, Turnigy servo slow on the flaps which also allowed one servo to be reversed, I setup a mix so the flaps came down 20 degrees with the retracts lowered and to 60 degrees with the flap switch.
Shame the servo slow is only available in the Australia warehouse at the moment, if you think it would be useful PM me and I can let you have mine as I don't need it anymore.
Here you go video
|Thread: Very low mileage older car - should I be suspicious?|
My wifes 04 Mitsubishi Colt has just passed 27,000 miles , as John says check the service and MOT records, if it hasn't got them then it will depend on the overall conditions, if it looks like a 40,000 mile car then it probably is
|Thread: Model design software|
Some simulations do allow you to create your own models and for testing on a flight simulator that would be the best way to go, but these do not produce a design plan you can build from. I have just been using Dev Fus and Dev Wing which does allow you to print out plans and even export files for laser cutting etc but these don't do things like optimise the wing profile, tail area or calculate the c of g etc etc
There are other programs around which will calculate the center of gravity, e.g.https://www.ecalc.ch/cgcalc.php
But maybe the best way is to get a book on model aircraft design to start with e.g. http://gb.trapletshop.com/designing-model-aircraft-by-peter-miller
|Thread: Cleaning Transmitters|
I cleaned my Tx using some DIY wipes and they wore off the logos on the buttons , just as well I know what they all do.
For cleaning my models I use Muc Off which is my bike cleaner, works really well.
|Thread: Redundancy in larger models?|
Dennis thanks, not too worried about what happens in a high impact event, but avoid one Seems like two FET type switches are a good option for dual battery installations.
I've used these on some models (with a single battery), at the weekend I saw a twin battery installation with these switches on each battery, because they are a FET type switch do they also act as a diode stopping reverse current to the "faulty" battery or would diodes still be needed.
|Thread: Channels vs Servos (DX8G2)|
8 channels means 8 outputs, i.e. 8 functions. You could Y lead (or say JR matchbox) the ailerons and flaps and possibly put the ignition kill switch and throttle on the same output if you can configure the killswitch to work on the throttle channel when the throttle cut button is pressed.
The other alternative would be to go with one of the newer flight controller/stabiliser units (e.g. MPX Wingstabi) which only use single aileron, flap, rudder, elevator inputs with multiple outputs, but in addition you'd need a gyro input channel.

|Thread: Adapting X9D to DSM2|
Unless you've got a bunch of BnF models wouldn't it be just as well to sell your DSM receivers and get some frsky ones, then you can use their telemetry sensors as well, a bit of vario on your gliders might be fun.
|Thread: Help me solve my dilemma....|
Why do you say that? both these models will fly the B certificate with ease, is it because it would be too easy ?
