Hi w8, if I were to get one without pump, will it be upgradable in the future, or will I have to get a standalone pump ?
Also, Terell mentioned about the OS91FS. What is the equivalent engine for Saito and YS ? Which is better in your opinion, in terms of power, user friendliness and maintenance ?
Will I need a stronger fuel tank as I heard about tanks bursting. Why do 4C engines generate so much tank pressure compared to 2C ?
On the subject of hovering, is this normally done with a 2C or 4C ?
Sorry for my inquisitiveness but thx in advance !...........
