I might end up with a Goblin in the end but I'll be god damned if i'm going to let this 450 just sit on my bench every day when i should be flying it EVERYDAY.

SCREW YOU WALKERA! I've already replaced almost everything with align parts and can buy my replacements at my LHS now. I'm only ordering a stock Crapkera servo to test if my 2702V RX is the reason for the burnouts on the tail rudder. After that it's Futaba all the way. I might end up getting new RX/TX & gyros too.

If anyone cares and don't know, almost all of the 450 pro's head, tail and main drive assembly is identical. You can actually replace the whole rotor head, main shaft, gear assembly, main gear, shaft sleeve, one-way bearing, one-way bearing tool, swashplate, tail blade grips, tail boom, etc. I think even the drive belt is the same too. The canopy is to shallow to fix right though but it seems EXI makes one that fits for only $3! I'm done giving my money to Walkera on this one.

Ok 80,80,80 kick butt. I thought i had a beast before , but now it is ALIVE!
Can i set those numbers to different numbers ? Like if i didnt need as much pitch...set it back to 70?

And i did my 1st auto with the v450 . It goes much faster than the trex600.
Im not sure if i will post video of today . Not many stunts but it was windy and i did have a close call!
give it up to the sim again for another good save

I still have the smallest wiggle.... That i have had from day 1 . I still blame the rx gryos not being able to be turned down enough. But im not sure...?noisy tail servo??

I had some issues i had to deal with the tail myself... /sigh. .

The stock servo sounded like a rattle snake when i first got the helicopter. The previous owner didn't have a farrite choke on the ESC RX wire and also has the ESC Rx wire tie wrapped up against the tail servo wire for like 2 inches and also in a coil with the rest of the servo wires. Once i installed the new ESC and isolated the ESC RX wire from every other wire and ran it to the RX on the opposite side from the rest the servo wires, it got a little quieter and ran MUCH cooler but still made a lot of noise and ran hot. When i installed the $20 Fusonic MG tail servo from wow hobbies it was quiet as a mouse and not so hot compared to stock, but still made a hunting sound. Till the motor inside burned out on me. So some noise i think is normal with the stock servo. Still waiting for my new one to arrive and i'm sure that will be noisy too.

If you've already checked for binding and everything normal to get rid of wag then just keep a close eye on your servo. If your heli jerks the tail or does something funny like mine did the last 2 times the servo went bad. You should set it down right where it is and check that the tail servo is not so hot that you can't touch it. Near the end of my stock servo's life it ran hotter than the ESC even though the steering is smooth and lubed and no binding occurs anywhere, on top of that i wasn't using the rudder for anything more than 180 degree turns in figure 8s in the wind. I'd hate to see your tail blow out on you like mine did. I had to learn how to auto with the 450 the hard way. It came down kind of fast compared to phoenix 4's 450 pro 3g. But i still managed to do it with out crashing hard. It was the impending RX auto-rebind and spool up because i didn't hit TH that took my main gear and one-way out

Damn rain came though today and i got bored, which usually makes me creative. I came up with painting my cracked up old canopy since i just got a new one in. It's only cracked on the bottom and it has some scratches, so not too bad.

I could use a few pointers if anyone has ever painted these before, this is my first attempt on this material. Since i figured NOTHING would stick too well to the outside anyway because of the material and gloss of it. I went ahead and skipped primer spray or anything like that. I suppose that might have helped because the enamel that i sprayed it with scratches off very easily. I figure if i can find something that will stick decent enough so that a dent won't chip it i could use polyurethane or clear coat of some kind to keep it from scratching. I'm just not sure what this material can safely handle. Now i know this enamel won't melt it anyway, at least it hasn't started too yet! lol. I was thinking a laytex enamel might work better, but would be quite a bit heavier and lots harder to find in a spray can so i would probably have to brush it on. I'd rather not.

Hey that looks really nice IHW........

i dont know much about canopies or painting them, as I usually fly without a canopy.....but thats a nother story. Anyway these 2 piece plastic ones as Im sure you realized are clear plastic and painted then sealed on the inside and glued together. They are probably clear out of the mold, so if theres a way for you to get the paint off without ruining the canopy from the inside, and then you could start that way.

If you do come up with a color scheme I bet you would sell a few and reoup some of that funny money this thing has been leeching lately.

I took mine completely apart, its in pieces, and Im sanding down the frames edges smooth. Anyone notice how rough the carbon fiber cuts are on your kits? Thats great for shorting out servo wiresthat rub edges and just plain old ugly. Some 250 grit wetsanding gets it nice and clean on the edge.

The funny thing about the V450 is you know it has potential. Some engineer in China took a lot of time and thought this thing out, even over engineered it in some places. But once production got thier hands on it and ran it through the dull CnC machines and strapped down the cheap electrics. This heli went down the tubes. Im trying to give er some life .....LoL Total rebuild.

Yes, when i purchased the v450 i was already confident in my ability to build a kit. Walkera is great for people like me just getting into the hobby this year. As far as RTF goes they are king, pretty much. At least for FBL systems, flybared could be very debatable i suppose. But i still bought the v450 because after examination of the Exp diagram and realizing a lot of people use the 2702V in their 450 pro kits anyway I came to the conclusion it would be a good starting point to make a custom 450 bird without having to start from putting frame slot A into frame slot B and secure with pan head screw and washer. BORING!! lol. If the CF frames at least came assembled it would be more appealing. But the Goblin..... Nevermind that again. Moving on! I was pretty sure i could turn this into a respectable heli. In reality it's performed excellently and above my expectations. Now as long as i can determine if the RX firmware is bad or not I think i can still proceed to making this a rock solid bird. The 09-9 V2 servos are working really well and seem to throw faster and smoother than the version 1s did. Still i think eventually i'll be getting some Savox MG servos and see how those do. I really think once i get the tail servo situated to where i can feel confident that it's not going to just blow out on me again in flight, I should be able to turn this into a respectable, reliable 450 bird. I don't really have the space here to fly a bigger helicopter like the Gobl-... Never mind that again.. I don't want to have to join the local modeler's club just to have a place to fly a bigger helicopter. Even though my 2 little fields are mostly sufficient i don't want to fly something that big where there are people and distractions around.

As far as the painting goes, repainting from the inside is just to much of a pain. But i think now that it's cured longer the paint is sticking better. Not great, but it's not scratching off when i sneeze on it anymore.

I used this in yellow. http://www.plastidip.com/home_solutions/Plasti_Dip It's not very elegant but I just wanted something that would remind me which one the front was! I lost orientation of this heli twice resulting in a crash, yet my smaller V200D01 with yellow canopy only once and that was when it was very high and into the sun, no crash. It sticks pretty nicely, but will also peel off if needed.

For 100 bucks it is very tempting to buy a clone frame and just transfer the electronics I got into this thing, and be done with it. But you cant beat the price of the ASlign kits that come with everything already in the kit. By the time you sell off the stuff that you dont want out of the kit it all comes out in the wash.....and someone else gets a good deal. Everybody is happy I still have a Trex 450-Pro thats my go-to heli, converted to Flybarless with Beast X on Spectrum DSM-X. Looking into the new DFC FBL head thats out for it. But that heli is set it and forget it, thats what spending the money up front gets you with this stuff..... this V450 is the mess around bird, a tinkerers delight. I live in the city and travel often so anything bigger than a 450 just isnt feasable right now. Plus if they go down its a 1/4 of a mortgage payment to get it back up in the air Then I would start talking to myself Lol........One of these days though because I do like the bigger heli's.

I'm still determined to make this at the least a reliable bird that i don't have to feel is going to fail on me. Right now, all i think it will take is taking care of the tail servo situation. A better ESC with a switching BEC will most likely perform better and get better flight times but the stock one i modified cools off so fast, I'm positive it would have fried by now when one of those tail servos went bad if i hadn't installed a heat sink. I'm looking into a cooling option for the tail servo now too. I'm not sure if the back plate on the stock walkera servo is aluminum or not, but it seems if it was an aluminum backing i could install a heat sink on the outside of the servo case and allow the down wash from the rotor to do it's work, perhaps instead, maybe cutting some slots into the servo case to allow the air to flow through the back section where the PCB is would do the trick. Though sand could be a problem too.

I actually have a can of this in black in my work shop.I've never used it though. Does it spray on evenly and dry smooth? or is it all clumpy and splotchy? I wonder if it can be painted over. I'm kind of liking this metallic aluminum color I'm using right now.

What is a good tail servo to use with the 2702v Rx ? A cheap one that will work well. Because I am just going to crash anyways

How about this one? Looks like lot of guys use these. It's for my HK450 FBL I just ordered. I figured I would by and build one of them to crash and save my V450.

The tail servo with the 2702V can be touchy. Get the wrong type of servo and it can be very sensitive according to heliflyer711 and others. I used this very cheap servo and it worked GREAT for the 4 flights that it lasted: http://www.wowhobbies.com/fusonicmg-...tailservo.aspx

The Walkera stock tail servo is actually pretty good, it just runs hot. I think i just had bad luck with mine, i hope: http://www.wowhobbies.com/fusonicmg-...tailservo.aspx

If you try that hobbyking servo let us know how it works out.

I just lubed and checked all my drive bearings. They look to be working like new at the moment. I'm trying the tri-flow "superior dry" lube you recommended. I'm going to compare it to what i've been using. Looks and smells like the same kind of stuff though. It soaked right into the bearings so thats a good indicator. Hopefully I'll be able to have more that 15 flights before having to ground the v450 for a rekit like this.

Nice little workshop too. Here is a photo of my "in home" work station. I also have a actual work shop outside that is used for actual work (and heli's). But lack of air conditioning gave birth to this work table equipped with a very nice parts box i found randomly in a hardware store.:

It's not a gloss finish and if you do it carefully it can be quite even. I just wanted anything yellow that would stick, not melt the plastic and was flexible to withstand the canopy being put on and taken off. The aluminium looks good though. I have metallic green and metallic orange polycarbonate paint from Tamiya for this purpose too but haven't got around to tarting up a canopy yet.
