how much of a difference will I feel going from 430mm to 515mm?

People are not to good, people are at work or asleep is all. And the people who did view may just not know, so its all good man....

In regards to your question I am assuming you are debating a 430mm sized machine such as the Logo 400 or t-rex 500 versus Logo 5003D for example? If this is the case the difference of that much disc is huge, honeslty it is night and day. The disc loading for the Logo 5003D is very little and the power to weight ration in general is pretty sick. The 430mm sized disc is certainly more appropriate for park or small field flying.

Hey djames,
Carnt comment on the 430mm size.
I have a mini titan (325mm) and a Logo 500 (515mm) the logo is of course alot more stable.
As you get more wind while you are flying you probably feel the difference more the stability shows up then.

Yeah, I was a little edgy about an hour ago. I was just anxious to get some replies. By the time I realized what I did, it was too late and I already edited my original post. I didn't mean to come off wrong. Anyway, thanks for the replies and I do appreciate them.:)

Having flown my T-Rex 500 back-to-back with my Logo 500 today, Shawn is absolutely right. The Logo 500 climbs so fast it still scares me. The T-Rex 500 much less so.

However, it isn't just rotor size. It's the whole setup and power to weight ratio. The Logo 500 is MASSIVE compared to the T-Rex 500 in p/w.
