Well I had some practice with one, but this Mugen is my own car to drive. It's been a while, but I learn fast. The engine I got is a Novarossi Top PT21 Sp1. It's old, but makes pretty good power. The RB S7c is a good engine and reliable, but powerwise it's quite slow. Browse around for Novarossi .21s and check the Rexs and Tops also. As for RB, they are all quite expensive so forget about those. You might be able to find a Novamega Evo engine around somewhere, but don't go with those ZXwhatever .21 engines. People haven't been having the best of luck when running them.

motor for your 8th scale
hey Joe, i have a rbc5 in my mrx4 it is modified and this motor is as fast as any that i've run against. i have only had the car a few months but am now used to the speed and the handling it is awesome and you sedan driving will improve alot. i don't understand why harkonnend would have two pictures of rb motors under his name and tell you their expensive and to forget about them. i have three rb motors in three years and they all still run and the worst thing is a crankshaft bearing that has gone bad. if you had the money for the car then buy any motor you want just don't go cheapor low on power. it better to have the power when you need it then not having it when you can handle it. I also race in florida so we will bump into each other sometime.
ps buy a nova based motor so when you want some real power and durability you can get a Palmaris brb piston and sleeve set

Engines
RB C5 is an excellent engine and price competitive with any other,Rody Roem has been one of the most innovative designers in rc cars,innovations have carried over to all the factory motors in one form or another.While I run max power and Murnan I can't knock a thing he's done or is doing.Another alternative would be a good R1WC kangaroo motor that you can still find new at attractive pricing.All of the P series novarossis are also good choices.Like any form of racing you pay for speed,you are better off to detune a race motor then drag up a dog.
