Hey Guys

Just a general enquiry - I noticed in the manual it states "IMPORTANT" do not run a tail rotor bigger than 95mm.

Hence I've just learnt I have been running a105mm tail rotor.

I want to do things proper - and am gona change down to what the manual states.

Whats the reason behind this?

No dramas .......

My manual (EP90) states you should not use 105mm blades if you fly at high rpm. If you fly around 1900rpm it should be ok.

Personally I do not like 95mm on a 90size machine.

Regards,

Jurrien
