Saved configurations (7 / 20)

Each pilot can keep up to 20 configs. The weight chip on each card encodes risk against the 300 g tech-inspection ceiling: gray when comfortable, amber > ~290 g, red at the limit. Selecting a card drives every other panel on the page.

Five build slots

Four swappable categories — Motor, Prop, ESC, Battery — plus a fixed cage/frame (95 g, structural). Tapping a slot opens the parts catalog filtered to compatible options for the slot. Weight on the right is the catalog spec, not measured weight (that comes later from the lab scale).

Build Summary

Total Weight: 286g
Component Part Weight % of Total
Motor iFlight XING2 1404 3800KV 53.2g 18.6%
Prop Gemfan 2520 Tri-Blade 6.4g 2.2%
ESC 20A AIO BLHeli_32 29.1g 10.2%
Battery GNB 4S 650mAh 75C 96.0g 33.6%
Frame 95g Non-swappable structure 95.0g 33.2%
All-Up Weight (with cage) 286g
Itemized weight

Where the grams go

Same parts as the slot list above, but flattened into a table with % of total so you can see at a glance which component dominates the budget. Battery and frame typically eat ~65 %, so most weight-shaving happens by swapping the motor or prop. The total at the bottom is the all-up weight including the cage.

Weight Budget (All-Up)

Tech Inspection Limit
Weight gauge

How close are you to disqualification?

All-up weight against the 300 g FAI tech-inspection ceiling. The gradient is psychological, not a calculation: green ≤ 60 % of budget, amber 60–85 %, red ≥ 85 %. The white tick is the hard limit — go over and you fail inspection at the meet.

Stat bars

Predicted vs. measured, on a 1–10 scale

Six core metrics. Dashed bars are the prediction from your parts (computed from KV, prop pitch, capacity, ESC current limit, etc.). Solid bars are the actual score after you log a flight test in the lab. Predictions get more accurate the more flight tests the team contributes — that's the “theory” in HoverTheory.
Six-axis performance radar chart Dashed polygon shows predicted scores: top speed 7.6, punch 7.2, flight time 6.8, agility 8.0, durability 6.5, weight budget 7.5. Solid polygon shows actual scores: top speed 8.3, punch 7.8, flight time 7.1, agility 8.6, durability 6.8, weight budget 9.5. TOP SPEED PUNCH FLIGHT TIME AGILITY DURABILITY WEIGHT

Build “shape” at a glance

Same six stats as the bars, projected onto a hexagon. Dashed = predicted, solid filled = actual. Easy way to see your build's character — a spear pointing toward Top Speed and Punch is an offense build; a balanced hexagon is a generalist; a polygon weighted toward Durability and Flight Time is a defender.

Insights & Warnings

  • Info: Main tradeoff: Top Speed ↔ Flight Time
    Improving one typically reduces the other.
  • Safe: ESC headroom acceptable
    Current draw at hover is ~62% of 20A limit.
  • Warning: 84% of weight budget used
    You have 14g remaining for future changes.

Auto-generated insights

Three flavors: info (tradeoffs the build is making, e.g. more speed costs flight time), safe (passing checks like ESC headroom), and warn (something to watch — weight budget, current limits, prop tip-speed). Each line links to the underlying calculation so students can see why, not just what.
