Well ive mounted the motor, programmed the esc. everything running smooth. Motor and esc dont even get warm. Very fast I cant hold the full throttle around my back garden . But 2 issues I noticed was that I tried a 2200mah lipo n it didnt fit so I used an old 1300mah for now but it lasted 10-15mins bearing in mind I didnt evrn use full throttle. Second issue is tyres n wheels..are there any other tyres that fit these apart from the jackal tyres? Can u put up pics of yours so I can see please.
