I have just had the most bizarre exchange via email with a company that sells frames who won't sell me just the frame I want unless I buy all the components as well from them i.e. motors, ESCs, power board etc. They said it's because they've tested various components, come up with ones they like and that's what they recommend. Is it just me that finds this odd? They can recommend all they like but surely it's up to me what I put on it, no? To me it seems all they want to do is make money on the frame and the components. Thoughts please.
