The adoption of a metal shell furnishes the FLAME 25A Pro with fine overall texture and favourable performance in heat dissipation, waterproofing and dust proofing. Customized chips are used in the FLAME 25A Pro whcih contributes to the increase in basic frequency up to 100MHz and code materialization in hardware. Application of motor electromagnetic observation technology enavles the precise inverting and speed change of motors which takes the full advantage of square wave drive. Parameters as to timings, braking, acceleration, and rotating directions can be adjusted via RC. Best of all, FLAME 25A is compatible with all the prevailing motors in the market.
