Flight log viewer (CSV) ?
Choose a CSV log from EdgeTX, ETHOS, Spektrum or Futaba and pick the values to chart. Nothing is uploaded.
Choose a log file
EdgeTX and ETHOS keep logs in the LOGS folder on the SD card. Up to 40 MB.
Values to chart
Tap to add or remove - up to 6 charts. Hover over or touch a chart to read the values; all charts follow together.

How it works
Radios save telemetry as a CSV file: one row per moment, one column per value. The viewer reads the header row, works out the time of each row, and keeps the columns with numbers that change.
EdgeTX or ETHOS with ExpressLRS: 1RSS is the signal strength (closer to 0 is stronger), RQly the link quality in % (100 is perfect), RxBt the receiver or flight battery voltage. FrSky receivers: RSSI and VFAS.

CG calculator Find the balance point of any wing - straight, tapered, swept or a flying wing - from a few measurements.
Wing loading calculator Wing loading in g/dm² and oz/ft², plus cubic wing loading - the fairest way to compare models of different sizes.

Battery position and CG calculator How far the balance point moves when you slide the battery - and how far to move it, or how much nose weight you'd need instead.
Balance point from scales Find where your model really balances by weighing it on two or three kitchen scales - nose or tail heavy, and by how much.
Glider ballast calculator How much ballast to add for a windy day, the new wing loading, and how much faster the glider will fly.
Turbine fuel and flight time calculator How long a jet can fly on its tanks, what to set the timer to, and how much fuel is left when it lands.
Range and failsafe check A step-by-step range check and failsafe test with a countdown timer - for any radio, before a new model's first flight.
First model finder Six quick questions about where and how you'll fly - and the kind of first model that suits you.
RC unit converter Grams and ounces, mm and inches, km/h and mph, kg·cm and oz·in servo torque, g/dm² and oz/ft² wing loading - all at once.
Fuel and oil mix calculator How much oil to add for petrol two-strokes (1:40, 1:50...) or turbines (5% turbine oil in kerosene).
