Brand new-bee here. Very exciting the last week or so reading about everyone's experiences! I'm the proud owner of a TRAXXAS SPARTAN and would like to know, besides the 3s 11.1v 5000 40c(50c burst) lipo's I'm waiting for, what simple add-ons might push her to MAX TOP END! Only prop's come to mind...what size??? Learned about adjusting trim tabs from all of you...THANKS...done. What else??? Thanks again...very willing student here, promise to post all findings...REGARDS TO ALL!!! Ciao
