Spool up time around 10 seconds from idle to full thrust.
The P-120 SE will be around half of this.
I find the 120 SE amazing. Same size as the P-80 ( the P-80 looks bigger due to its shape ), almost same weight, extremely reliable, very fast and 50% more thrust...

The P-60, P-70, P-80 are now completely outdated due to the release of the new high pressure ratio class of engine:
G-booster 80+
Merlin 90/ Jet Central Rabbit

These engines weight around 650 grams without accessories and deliver 85 to 90 N of thrust.

Jetcat has some work to do the catchup like they did with the 160 SX.
