Hi i decided to get a micro at the end of last year with a mate to race we both went down the EMB-1 kit ( not rtr) as they need nothing out the box we did not have a clue on motors lipos and speedos after atending a meeting local to me we talked to Craig Harris from Thumbs designs and armed with what we needed to know.
we got the leopard 5200 Kv motors
and both got the hobbywing ezrun 60amp speedos
these can be got from thumbs designs direct
lipos we got from hobby king i think £7.00 each
well what can i say i did the last 2 rounds of the nationals and what a hoot in this guise there super fast easy to drive and the cars are bulit proof my mate has since got a carisma aswell but needed to upgrade a few bit out the box but its still a great car.
only thing i will say on the EMB-1 is get a carbon fiber top deck as kit one is crap also space is a premium in these kits so some jiggiling is needed i cut one lug off the servo and mounted it with double sided tape and one servo mount it dont move and there are no issues also the standard servo you get with the kit is more than enough. so massive thumbs up for the EMB-1
hope this helps.
