1S Mini Delta Page

2S Version Setup
We recommend the Mini Delta be set up for 1S (3.7 volt) operation. A 1S setup will give the best flight performance.
However, if you choose to set it up for 2S (7.4 volt) operation you can use the information here as a guide.

Please note the following
Piloting Skills
* This aircraft is very fast with a 2S setup. You will need to be an advanced RC pilot to fly it.

RC Construction and Electronics Setup Skills
* Setting up the airframe for 2S operation is for advanced RC builders only. 2S (7.4 volt) setup requires an ESC / Receiver
and servos suitable for this voltage. You can't simply use 1S components with a 2S motor. We provide a list of components here for 2S setup as an example. If you are not an experienced RC builder and are not sure how to set up a 2S system, we suggest you set the airframe up for 1S operation instead.

Flight Video
Flying at a sports ground late in the afternoon. There was a little breeze above the tree-tops which affects the plane at times.


Components
To set this airframe up for 2S operation you will need to combine an RC electronics package which will operate at higher voltages compared to most micro RC systems. Most micro RC components operate on 1S (3.7 volts) and will easily be burnt out if connected to a 2S battery system. Connecting a 2S battery directly to your receiver will most likely give a pass-through voltage of 2S directly to your servos, so you will need to ensure your servos can also handle that voltage. If connecting the 2S battery to a suitable 2S ESC, the ESC may either pass on that supplied voltage to the receiver and servos or if it has a BEC it may pass on a voltage of around 5 volts to the receiver and servos. Check all the voltage limits of your system first.

Suggested Setup
The components listed here are same ones as shown in the video below and will give a reliable 2S setup.

  Receiver 4Ch FrSky Bare Board
This is an FR Sky receiver. There is no alternative for DSMX/2. The receiver can operate on voltages from 3.5 - 10 volts making it suitable for being powered by a 5.5 volt BEC from an XP-7A ESC.
  ESC XP-7A
Has a 5.5 volt BEC for powering the receiver. Custom soldering is required if connecting to the receiver above.
  Motor AP05 3000kv 1-2S
This motor will produce about 65 grams of thrust with the suggested prop which is more than enough for this airframe.
  Prop Set 90mm 4mm Bore
Use this version of the 90mm prop with a 4mm bore and a prop saver instead of the version with the 1.5mm bore. Because the Mini Delta skids to land a prop combo with a prop saver is necessary.
  Prop Saver Alloy 1.5mm
Suitable for the prop above. Spare o-rings are a good idea.
  Servo BlueArrow D03013
These micro servos can run on 4.8 to 6 volts making them suitable for the above receiver / ESC combo. The receiver above has no connectors so you can either cut the connector off and solder directly to the receiver or wire up the connectors linked below.
JST ZH 1.5mm DIY Connectors.



These additional wing ribs can be purchased using the button below and are designed specifically to accommodate the BlueArrow D03013 servos


  Nanotech 260 mah 2S battery
A 2S battery similar to this in the range of 16 to 36 grams. The maximum battery size which can be accommodated is 85mm x 29mm x 12mm. Or if thicker than 12mm, a battery of maximum size 41 x 29 x 16 can be accommodated in front of the brace in the middle of the airframe.
     

Throttle Mixing
A 2S setup produces additional thrust and speed which will in turn produce more lift. You will need to mix in down-elevator on both channels to compensate for this. Start off with a small amount and adjust as needed. For the throttle mixing create a custom mixing curve with zero mixing from 0 to 50% and then proportional mixing from 50 to 100 %.

* As an advanced RC builder you will not need to contact us to ask how to do this.
