Hello!
First of all I am a little bit newbie with "new" (I am lost in studded) generation technic and rebrickable.
1. ni-zn batteries are recommended with this set? Could it do damage/disadvantage?
2/A. I am thinking to do Effermann moc. Is it a good final upgrade?
2/B Rebrickable calculated that with the 42099 set I have 71.9%, exactly: "685 out of 953 , ignoring 1 minifig/non-LEGO parts". Ideas whats that part?
2/C Did anybody bought the missing parts trough rebrickable database? 268 necessary parts is correct (if u have only 40299 set)?
Thanks for the reply!
