Nitro I'd probably go with a raptor. They fly good and parts are affordable and eay to find. Electric probably the T-rex series.

If the wings are traveling faster than the fuselage, it's probably a helicopter.

My Posts This: Topic  Forum		2nd Trex 450

I learned a lot and very inexpensivly on my Trex 450. The advantages of low-cost repairs and fly in your driveway convenience is hard to beat. The one thing that will sharpen your skills quicker than anything else is "STICK time" and with the time constraints we all face today its very handy to just pick up your Trex and step out into the front yard and fly. You can adjust your radio settings to tame down the Trex to handle very well even for a novice.

My advice is get a used Trex 450 from someone who is well known here on RR, read and study as much as you can and if possible get local help and have fun.....GET-R-DONE - just fly.

My Posts This: Topic  Forum		Dude, Go with the T-rex 450. You crash parts are cheap in the 450 world. I know am about to graduate from it. Make sure you get the HS-65MG Hitec servos. They saved me alot as many times I crashed. They're fast enough and they dont break when I crash. I think I put mine in the ground once a week and servos held well. Someone mentioned wooden blades while learning earlier good idea but I googled some glass fibers and got them for $5 a set forgot where but to me they worked alot better. Falcon 3D: BIG NO GO / Blade 400 3D: I have one great has a easy hover setting but the Trex is a much better choice and you will prefer it in the long run. I think am the only person that brings a blade 400 to the field still. Also ask the guys on here questions they will not hesitate to help. There is more than enough knowledge on here for your need to know. Trust me I know.

My Posts This: Topic  Forum		Being new to this hobby myself and having only exprienced the T-rex 450 I can only speak for this helicopter but I think it's worth sharing my experience in this hobby.

I bought a 450 and built it up from scratch. Take your time and understand how this machine works; this is important.

Get a good flight simulator and use it as much as possible. However using a flight sim is nothing like the real think so I also got a ready-to-fly indoor heli (I used Walkera 4B1) which will not be wrecked each time you crash it while learing.

After one month of practice on the sim and lots of indoor practice (including many crashes) I was able to maiden flight my T-rex 450 sport in my backyard and keep it in a hover.

I am now learning the nose-in orientation and I must say that I gain so much of practice and confidence with this orientation by using the sim and Walkera combination.

The only problem I have at the moment is that the 450 has developed a serious wobble (can't figure out where this is coming from).

My Posts This: Topic  Forum		Is your wobble For and Aft or is it Tail left and right. For and aft with mine I had to replace the rubber oring in the head around the spindle shaft bcuz it was torn. also check for slop try to get it as solid as you can and still have free movement. Others might disagree with me on this one but for left and right wobble check your gyro sensitivity if you turn it one way and it requires more input, give it small increments the other way until your out of that sensitive spot. Like I said others might disagree with that part but that worked for me with a $01 and a HDX servo. Am also new myself.

My Posts This: Topic  Forum		Hi dwight2k, thanks for your suggestion. In fact its really a wobble; I've read the forum about this sort of problem and in my case its not a nod (front to back) or a wag (left to right) but rather the heli seems to be wobbling around the axis of the main shaft.

What's strange is that my first few flights have never had this problem. I then changed my pitch curve for normal mode to get to zero pitch at center throttle (which many people suggest) and immediately after this I started encountered the wobble. I may also have changed gyro sensitivity settings around this time.

I will also strip the head to inspect as you suggested but with only a few flights I would expect it to be ok.

Thanks for the input.

My Posts This: Topic  Forum		Of the three you listed in your post +1 for the T-rex 450 Build.

Learning how to build and maintain your model is important and a big part of the hobby.

Learning to fly is difficult enough on a properly set up model no need to add more problems with a poorly setup and outfitted model.

I tried the budget(cheap) route it doesn't work out by that I mean you will buy twice = Spend more than doing it right the first time.

This hobby has taught me to be patient even if that means it takes me a year to save and buy all the proper components to get a model in the air. Well worth the wait when it all comes together with quality components. More time flying than dealing with sub par airframes and components.

Take your time do it right the first time.

Someone mentioned some great videos on building a T-rex 450 Go watch them a few times makes the idea of building less intimidating. I know they helped me.

Check your blades make sure they are balanced in weight. There's alot of videos on blade balancing on youtube. If you are using woodies make sure the shrink wrap isn't coming off and catching wind. Make sure your main shaft and your spindle shaft isnt bent. Just want to make sure you check all your bells and whistles before changing your gyro. Another thing I've learned is you don't have to have it set at zero pitch at mid stick. I used to always do that until a guy at a hobby shop asked me why and I said because my book said so and the guys online do it that way. He asked me if I do 3D I said no I'm gonna be scaling. So he set me at 5 degrees half stick for normal mode and flat pitch half stick on stunt mode. Everyone on here have theres set the way thet want. I have the 0 25 50 70 100 on my throttle curves normal and 85, 85, 85, 90, 100 stunt. I forgot what I have my pitch curves set at but I did most of it at a hover and on the ground to my liking. All the guys on here will tell you theres and it'll be alot different stuff. I like to hove at one notch above 1/2 stick on normal mode thats why I have it set the way I do. It's all to your liking and comfort.

My Posts This: Topic  Forum		Trex450 has my vote for lots of reasons already stated. I would go for a used Trex450SE V1 or V2, also mentioned earlier. These can be had cheap and are great helis. Parts are cheap, crashes aren't terribly expensive. It is lots of fun to do a complete build but honestly I wouldn't spend the money on a new kit for my first heli. You can get a used V1, V2 for 1/2 the price. You will learn how to build soon enough Good luck with whatever you decide!

EDIT: Oh yea almost forgot, get a sim, get a sim, get a sim, hehe.

even not doing anything would have been better than nothing...

Main CF blades were balanced including check for CG when I put them on (only a few flights ago; this is a new heli) so I think they are still in balance; I will recheck though. I've stripped the head and all looks perfect except the main shaft has a bit of scratch marks located where the metal ring which eliminates vertical play on the shaft. Not sure what this component is called but its placed around the main shaft just above the upper-most bearing block and contains two grab screws and seems to eliminate vertical play on the shaft; I'm also not sure whether I should allow a bit of play here or not (the manual is not clear on this point).

Only thing I can think of is scratching from the grab screws but this is strange because grab screws look absolutely new and were locked well in place when I stripped the head.

I've also further improved on the swash level before replacing by adjusting the linkage rods to the servos.

I've also loosened the main blade screws slightly as I felt them to be too tight.

Net Result - Wobble still there but seems to be slightly less severe than before. Wobble is also independent on pitch curve setting; i.e. even if I set it back to original setting which I had when the wobble was not present.

I must also indicate that on one of the preceding flights I slightly touched the tail blades on the concrete surface but they still look ok; just a scratch on the end points. I will also check balance on tail blades again.

I really don't think it could be the gyro but to eliminate this possibility I can swap out with my Trex 250 which I am busy building.

I plan to replace tail blades just to eliminate this possibility and possibly also main shaft due to the scratches I've identified.

I've also taken a video of the wobble and I will inspect the wobble closely without having to focus on keeping the heli hovering.

Thx for the input; I will update on my findings and results...

PS I'm new to this forum; not sure if should I move this post into a new thread as it now drifts away from the original topic...

My Posts This: Topic  Forum		Grab a hold of your main blade grips. Hold one side so it won't move and try to rock the opposit side up down back forth. do the same on the opposite side. You should have little to no play in this area. Also when you put the head back together make sure that the grips are free moving without binding. Also the part around the shaft (main shaft lockring) is ok if the screws put a scratch or scar in the shaft ans long as its where its locking and not where parts move on the shaft. Make shure it is slid all the way down and your shaft has little or no radial play at all. As far as the gyro hang testing: if it wobbles left to right its usually the gyro, up and down its probably in the heard somewhere. You kinda have both going on. You also said it didn't have this problem so unless you damaged your gyro it shouldn't be the problem. I would Also try to place the settings back to where you had it before the wobble and see what happens. It could be your head speed. Also yes you can also start your own thread to see if one of the other guys on here have any suggestions.

My Posts This: Topic  Forum		I would get a protos 500 from rcdumbthumbs.com
Its bigger than the 450 and the parts are REALLY cheap
its more stable and for a beginner its really nice.

My Posts This: Topic  Forum		How about the hk450. http://www.hobbyking.com/hobbycity/..._Helicopter_Kit

But for your elc. stuff buy the best that you can afford. People have had good experience with the chargers/batters and they are cheep.

You will have to look up the build though, because I think this kit doesn't come with a building manual.

But for a nub that is going to crash there is nothing better then a great cheep 450. The kit is 100% t450clone. So as you get better you can upgrade this kit to a triked out T-450. But My advice to you is as much as you will be temped to, don't. Save your money for the next heli that you realy want. What I've learned try to save up your money and buy ones. Up grading comes out to like buying two to three helis in the end in the money that you spend.(not with this kit though)

Know the cat is out of the hat, know here comes all that will bash the clones.

My Posts This: Topic  Forum		For a beginner if you can afford it go with a .50 glow (nitro). Much easier to learn to fly. You come along much faster with a bigger model combined with the SIM and some personal help. Get some one to help locally if possible.

I started with glow and then pretty much exclusively small electics but recently got back into the bigger glow helis. Forgot what I was missing. I like to fly my T-Rex 700N the most but my Rave and Blade 400 are there for the convienence.

My Posts This: Topic  Forum		I agree with Acid. I started on a 450 and it is very time consuming, when I got the protos its much more stable and not so twitchy.
I have seen the new pantera and it looks good and inexpensive
like the Protos.
