which would be better?
I'd buy the B400 because you know exactly what you are getting where the quality of the clones can be very unpredictable. If you really want a stable 450 that handles well, the TT mini titan has a superior head design and is a better heli.
The mini titan is a nice stable heli most of the time ( I have heartd that some people have constant issues wijth keeping the blades tracking straight). I have one and love the way it flies but don’t like the Heli. Its got tiny ball links that are a constant pain in the backside. I’m also starting to have problems with blade tracking.
As for the HK450 I also own a couple of these. They most certainly are not for a beginner. They are not particularly stable.The plastic head will break very easily ( the quality of the plastic is not that good). At some point you will run into problems that are difficult for a beginner to handle. If you do go the HK450 rout I’d suggest replacing the head and tail with CNC upgrades.
Another option you may want to consider is getting something closer in size to your raptor. A Trex 500 EXI 500 or Hurricane 550. It will handle more like the 30 you fly.
I personely havent flown one but I have a buddy that has one. He likes it. There are also a few clones out but I havent seen any myself.
You may be able to find a used hurricane 550 if you poke around a bit on this and other forumns. They make great training Helis, very stable. As I understand it the SA (plastic framed version) doesnt make a good 3d heli, frame flex causes problems. I have the CF version and have afew years on it and its aways been a good machine. Anotherthing I liked is they are designed to use to2 3 cell packs so I didnt have to get a6 cell charger at the time all I had was a poly 4.

Your certainly not invading anyones territory feel free to stick around, the waters fine I just hate to see people recommend products that they have not had any experiance with. Please share your views and opinions but I would suggest limiting your advise to iteams that you know like the swift or at least make it clear that your using second hand knowlage. One of the most frustrating things about the forumns is having to sort out information from misinformation.
Did your nephew add the third bearing block? I friend has one I'm not sure if its an early version but he had a problem with it pie panning in hover. after trying a lot of things like swapping out the bearings the final fix was to add an optional 3rd bearing block. But as far as I know its not a common problem.
