Default Christmas budget 450 scale multi blade build

OK, Is it even possible? I'm going cheap. I'm currently flying my Blade 230s pretty nicely with no crashes. So, I've searched parts, a copterx 4 blade ridgid head, tarot 450 pro air frame and tarot 450 pro torque tube tail, and a Ehirobo jet ranger to somehow mimic a Bell 407 because I love it. Air frame only parts came to $160. Fuselage-$70.The 500 size are too big and costly for me. My first issue to address will be head-speed.{1400-1600rpm's). I'm no pro, so what suggestions do you guys have to power this bird that really does seem impossible. Would I have to use a 3's system? Is a 6's possible? From my research, rotor headspeed to tail speed for scale flight is the biggest concern, and since so, a five blade md500 may be the only fuse that would look scale with this idea since copterx does make a rigid 5 blade head. OK, I know some gearing change mods may be in order(if they exist) to get it right. Also, I know a custom longer main shaft will be needed and longer control links.With all that said, descent electronics, and some perseverance, would you guys with experience advise the attempt, or say scrap the idea. I like the RCAerodyne Bell 407 470 size, but first off, they are out of stock and I get no response, also they are belt driven tail, which torque tube is just down right COOL.
So, please guide me in whether or not to waste the time, money and effort. I'm always reading you guys scale forums, and just can not afford a 500 size heli and my flying area is limited. So, scrap, attempt, or md500? Cheers and Happy Flying

I would recommend placing a wanted ad on here and RCgroups and see if you get any response, that's how I found mine. The 470 is the best value for the money in my opinion, despite the belt driven tail. The scale look of it is excellent!

If you keep with the 450 option, I would go with either 4S or 6S. 3S will likely not be enough power for a scale airframe. Your choice of parts looks good to me.

Thanks Enstrom Pilot. Everyone else please chime in with opinions and advise. At one time, when the rc Aerodyne 470's were available, I even considered trying to get just the fuselage and modifying it to accept a shaft driven 470 set of mechanics, but the site never sold just the fuse. Now, its been a while with only the cobra showing in stock. And since this has now become a quest to find out, more advise is needed. RC Aerodynes 450 size fuses would be part of the solution if they would ever get them. I've e-mailed them several times, no luck. So, since this is now a fun budget Christmas build attempt, back to the drawing board. A 470 scale build on 6's power would be perfect for a lot of people. Too bad, so sad though. I really did not want to go the md500 route, but it may be all thats offered in a 450 size. Cheers and more opinions needed. Oh yeah, I really love the look of the CopterX floating 450 4 blade head for a budget multi rotor head. Question is what heli would be right for it. I'm open to option this out for fun discussion. Lets have fun with it. Happy Flying

For other 4 blade options, depending on how you are with customization, you could cut down the skids a bit, fabricate a custom fin, and have an OH-6A.

Been a while but this 450 is now in test hovering stage with an el cheapo beastx clone flybarless unit, a TGZ380 from banggood and is holding and hovering well. Im just no good at the counter acting swash style of flying so I'm gonna keep it pod and boom and hopefully not crash it. Not sure if its worth a self leveling unit. The only way I could set the elecs up was on the sides and fbl on top in the back so to balance it I'll use a 2600mah lipo and a little nose weight and get 4;30 flight, well hover and call it a day. I have it way tamed down and it will stay pretty still, its just if I start moving around its fly or die and Im sure many people crashed learning this and I just don't have the time or money, so I sure hope self level becomes a standard. If it holds up pretty good, I may put a spirit on it and see how that goes. If that goes well I may get zeal mains, already ordered tails, and a nice canopy. Ill fly it occasionally so as to not burn it up, lol. Cheers
