Hello! And welcome to the world of Arrma! I am not sure about races,but depending on your track layout, be it a high speed track or technical track you will have to down or up size your gearing. I am more to bashing myself so I cannot really help you on that. Sorry!
As for upgrades, I did and upgrade with all HR aluminium front and rear braces, aluminium steering bellcrank ,aluminium steering servo mount and horn and link with the savox 1210SG. I had also purchased a Futaba 4PV with temp telemetry sensor and heatsink with fan from yeah racing. I had also the t-bone front and rear bumpers and mudguards (as I am setting up my ride for bashing) and installed some serpent o-rings on the diff cups on the rear dogbones as well as the front diff cup, centre and rear diff cup. Right now waiting on some other parts if not,I Guess all should have arrived lol. This hobby is poison. Once you start upgrading, you will never stop. I have not ran my car with all my upgrades yet. But I feel that it will be rewarding with all my effort worked out on the Typhon. I cannot wait to run it,but I am taking it slow checking alignment and servo travel and the esc's setup for the EPA. Gona be having a short antenna tube(shall see how) but not coming out of the car body. Right now motor is out of my car as I am having a total shakedown on all,if not the important screws to be threadlocked.
Oh yea. I also sprayed UV coating on my body shell but not on the nylon wing and dry lube on bearings from the outdrive and hub bearings as well as the front , centre and rear bearings. And as I said,I cannot wait to run it ! I rushed my build n setup for my other cars and it didn't turn out so well. Haha! Wheel nuts coming off, slack on drive train,play in steering,unequal servo travel due to minimising error when centering servo horn= too much trim on one side. All these nitty gritty stuff are magnified at speed( I Guess) so I Guess that my parts that did not come all at once was actually a blessing in disguise. I'm loving this buggy even before I run it. Hope you will enjoy your vehicle too! I'm gona start with a 4s pack for a feel of the vehicle first. (Hopefully next week).
Do not be afraid to ask as there are many helpful veterans here willing to share their knowledge and experience so you will not go through the same heartache or troubleshooting because they have went through it.
Cheers!
