|Thread: Flap / down elevator mix|
The 'light weight foamy' in this case (Carbon-Z Cessna 150) is 2.1 meter in span & weighs 10lbs! Not as big as your warbirds maybe but I think still reasonably substantial.
I have a Carbon-Z C150 & have -10% (ie down elevator) at half flap and -22% at full flap with an offset of 30%.
The C150, both model & full size (I have a share & about 500hours in the full size) both have a strong pitch up tendency when you lower the flap.
And I disagree with Jon, half flap helps shorten the take off run considerably, the extra lift more than compensates for the extra drag.
It's a good fun model, you will enjoy it. If you haven't already done so check out Duncan McClure flying his demonstrating the A Test on the BMFA Achievement scheme video.
|Thread: What Traders are still offering Mail Order? Services?|
Retromodeller, replied to email within a couple of minutes & order on its way.
|Thread: LiPo storage|
Finished doing mine yesterday with a ISDT discharger. Don't forget to bring your Transmitters down also if they have Lithium batteries.
|Thread: Email for a mac|
iCloud mail is certainly an option.
After a few switches I decided to buy my own domain & authenticated smtp access so my email (john@john******.com) is independent of my provider. The original host for my domain was taken over and is now names.co.uk who have been fine. I've only ever had one bit of technical difficulty & the response from their support was pretty much immediate with the issue sorted within a couple of hours. Total cost is about £4pm.
|Thread: Is there a new breed of servo ?|
In case you are not aware there is a comprehensive spreadsheet of nearly 2,500 servos at Servo Database , you can sort the results by clicking on the column headings, filter the results & click through for individual specifications.
|Thread: Isolating A Lipo.|
Simple 4mm plug into an embedded Jeti anti spark female, worked for several years with zero issues on my Sebart Angel.
|Thread: CAA height restriction and BMFA exemption question|
"The CAA recognises that a 400ft height limitation can be difficult to achieve for some aspects of model flying and we also acknowledge the good historical safety record that model aircraft flying has when operated under the ‘best practice’ offered through established model flying associations. In recognition of this, permission to operate above 400ft, under certain defined circumstances, has been issued to a number of UK Model Aircraft Associations for use by their members. Please contact your association for further details of the conditions within this permission."

|Thread: Boulton Paul Balliol|
Bouton Paul were taken over by Dowty's in the 60's. Back in the early 70's I had a work placement from Uni with Dowty's & was able to get hold of detailed factory drawings of the Balliol as I always thought it would make a good model.
The design & construction were beyond me so the drawings were passed on to a Clubmate who already had several model designs published in the mags with a view to producing a control-line version. Alas the project came to nothing & with the passage of time all has now been lost.
I'd still think the design would lead to a nice scale replica though.
|Thread: Eflite UMX Timber|
Yes they have combined the power & balance leads in one as I have illustrated above. That is why you need a special charging harness.
I acquired one of these models from a Clubmate who was giving up & know your difficulty. The problem is the batteries, connectors & wiring are pretty much unique for a fixed wing model, although I believe the arrangement has been used by some Blade helicopters:
A conventional charger will not work without some adaption.
I think you have 3 options:
1) Rewire to 'conventional' plus & sockets
2) Purchase the dedicated charger you were looking for, E-Flite EFLUC1007, they are no longer in production but I have found one here
3) Make up an adaptor lead for charging as alluded to in your OP. That is what I did. You will need a 2S balance lead, I salvaged one from an old battery, a Mini Micro JST 2.0 PH 3-Pin connector, available from Amazon & elsewhere for pennies and the input plug from your charger, mine uses XT60. Here's what I ended up with:
|Thread: spectrum updates via Mac|
On my Mac when I download the folder it appears in Finder as 5 .pdf instructions in various languages & 7 .svx audio files, again in various languages. I can't open the .svx files on my computer, but there is no need to do so.
Put your SD Card in your computer & then simply drag & drop the English audio file into your SD Card showing in Finder under Locations. Then eject the card & follow Spektrum's instructions for loading it into your transmitter.
Hope that helps.
|Thread: Receiver mounts/clips|
Here you go Neil, I came across them for my Jeti but they also do HoTT mounts
|Thread: Custom wiring|
|Thread: Best DV11 plan|
It's 50 odd years since I saw Norman Butcher's Fokker DVII win the Nationals, possibly the last time the event was won flying on reeds (pre-proportional radio). It certainly flew well & the plan was published in Radio Modeller, which Norman co-edited.
|Thread: Beware using PayPal with HobbyKing (and maybe others)|
HobbyKing sells product in USD only. Any foreign currency exchange rates on HobbyKing.com that are not USD are indicative only (you WILL be charged in USD regardless of the warehouse that you purchase from). HobbyKing.com provides the exchange rate tool as a guide only.
Alan I think you will find when you get your credit card statement it will have been converted from US$ such as:
.....and preferably use a credit card that does not load the foreign exchange transaction, such as Halifax Clarity or Revolut
|Thread: Ebay sellers...|
The most unusual Super 60 I've ever seen. I'm not knocking the builder/seller in any way, looks a very nice job.
