I've run out of pedal and lost TRA a couple of times in an L3
L1 C30P and L3 operate in PNG to fairly high altitudes.
Can get into 10 to 11 thousand feet with upto 2 X 200Litre drums of fuel on the line without LTE occurring.
Suggest you get TR control rigging checked for full left travel, carry out PAC to ensure engine is performing, perhaps assess your technique.
Have a look at the 407, the TR didn't grow with that model either by the look of it
mmmmm perhaps you would like to have another look yourself, I'm looking at S.No 538xx and it has a completely different TR hub and blade assembly from the 206 series
Put the same rotor on an L1, with more power, and it's getting flaky. Add a C30 engine, in an L3, and it's less than adequate.
The L has a smaller TR than the standard L1 which inturn has a smaller TR diam than the L1C30P ( ASI or PHI STC) and L3.
