hi doutrnz , and bill delong yes the kits you have to build and then choose your motor you want to run whether it be elecctric or nitro you will always have a spare motor or back up as you choose when you race , that s what a lot of racers do also tuning nitro
here in the east the humidity constantly changes , the nitro fuel becomes hydroscopic ( attracts water ) so tuning is constant , in the heat and mains . yes the good kits are tekno kyosho mugen seiki losi xray electric and nitro with nitro you have to learn
to tune your nitro engine properly , you can down load the manual of nitro engine tuning by ROB PARIS he was the grue of nitro tuning and paris pipes ( exhaust pipes ) . well electric is easier plug and play yes the tekno eb48.0 is nice along with
nb 48 nitro buggy and the kyosho , mugen , losi , xray team associated and they are faster good luck with your choice ok how fast does your wallet go ok mugey
