Just my 2 bob for what its worth, Im just starting to do a bit of 3d close to the ground, been flying for a few years, im not saying I cant hover nose in I can, but even at the stage im at I dont feel totally comfortable hovering nose in for that long, I think what im trying to say is sometimes its better to run before you can walk, just try new things fast forward flight or whatever, ive known people that stay hovering tail in and never got any further than that, probly due to the fact that they beleive if they cant hover 100 percent perfectly so theres no reason to try anything more, im not even sure I can hover 100 percent properly but its more fun to throw the heli around the sky and have a crash once in a while, ive also found that the time that I learn the most is when everything goes pair shaped and im forced to get out of it whilst my heartrate is at 1000mph, I think ultimately its an adrenalin sport and if you try and keep things to safe you can end up becoming bored and giving it up all together((i know people who have hovered tail in 5 ft of the ground for what seems like a lifetime and it cant be nice for them)), force yourselfe to learn fast figure of eights(fast forward flight) and when this is no longer a frightning experience move straight onto stall turns and loops(I think flips are easier) and so on, just make sure your heli is set up for this first though.
Also remember that fixing a crashed trex may cost you at worst 50-100 bucks, so its not the end of the world.
I know that most of us start of with trex 450s, I did.
But the larger helis electric or nitro are far easier to learn on and fly, if you can fly trex you can fly anything.

1- I'm gonna need new blades (got 2 sets of Align 325 for special occasion; do they need any mod to put them in? they are skinnier than the blade!:confusedIf not a have 2 set of stock ones!!

2- All servos need replacing!!(good time to upgrade!)Will go shopping tomorrow

3- Feathering shaft is more crocked than a politician( I don have one. Will go shopping tomorrow)

4- main shaft was bent ( I had a feeling so I took it off rolled on the desk and yes was bad!) replaced!!

5- main gear was strip (missing teeth just like a meth-head!!) replaced!!

I'm not sure about the fly bar!! And that's what scares me because I have no clue how to set the paddles so they be like they supposed to! But thanks to you I'm gonna look it up on that site to see if i can find it!! Thanks

POS These hobby you have to learn repairs quick and the hard way too!! Did that happen to you? Did you have someone that help you out, or just like me manuals and inter net?



1- take apart 2-repair damage 3-check everything 4-go fly and crash 5- repeat #1

Spitfire - I hear you. But honestly, if I spend the rest of my life doing tail-in hover, and that's what I'm having fun with, then its all good! I'm not trying to become the next world-class pilot - I'm out to rip up the skies. There is something completely and totally cool about helicopters (as I'm sure we all can agree.) I'm not concerned about remaining stagnant in my abilities, but even if I did, if I enjoy it, than it serves the function I was looking for.

What I do agree with you about are the crash costs. When I finally crash this rex, it won't cost much to fix, and I already have a small stash of spare parts laying around. Another heli (the Pantara for example) would have significantly higher repair costs; and this may be the reason I stick with the trex well beyond the initial learning curve.

I'm simply flying the hell out of this little heli when I have the time. I think I've progressed far faster than I thought I would, and I really can't wait to get into faster forward flight, piros, etc. But as you say, I need to walk before I run.

That sucks, man. Yeah, I just jumped in by myself and have been working slowly. I agree about learning about the mechanics quickly. Just like motorcycles...

just wait till you start getting up in the middle of the night to fly, trying not to wake the wife up! #1 sign of true addiction! sounds like the battery you was talking about has a over- discharged cell. all lipos run that risk, regardless of the manufacturer. does youre esc have low-voltage cut off?

damn, that was close!

I don't know about the esc. I've got an align esc, not sure of the model (I'm not home at the moment). I'd be pretty pissed if I over-discharged the pack. I've only flown for 5 minutes on each pack, always. And that particular pack is freaking huge.

I'll follow up with this. Additionally, my blinky balancer will be here soon. Will that fix anything or is the pack pretty much shot if one cell has been discharged too far?

first you need a caliper, second , depending on how much bent it is on that small of a heli, they are so cheap just get a couple new ones. third, get the exact same length of the flybar on each side with the caliper without the paddles on. fourth, screw on the paddles with the exact same number of turns on each side.. on my trex 450 i do about 21 turns or so.
hope it helps...

Updates for anyone interested:

Ah ha! I've found that tail wag issue! It looks like I need a little piece of fuel tube or something similar to remove the play in pitch slider thing. I can't wait to get this thing fixed up and get rid of the wag...

I almost crashed today. Came down pretty hard - you guys who told me not to put the negative collective too far were right. No damage, but I came down pretty quick and hard.

Got an order from helihobby coming in... new canopy, pitch guage, lipo monitor, etc. Now if Tower would just get the freaking blinky balancers in and ship me one I would be all set.

Also got my motorcycle almost put back together with the new paint job. Man, summer is gooooooood.

I wouldn't worry about moving to a different machine because of skill level. World class pilots fly 450s too! A quality 450 will take you as far as you set it up to go.

You know, that is my logic, too. My little rex is far, and I mean FAR more heli than I need. More than I'll ever likely need, actually. I love the hell out of flying this thing.

That being said, that pantara is sweeeeet, and so are the swifts... hmmm.... swifts....

Yes, I'm definitely hooked...

what head speed are you getting and what flight time?

Don't know about headspeed as I don't have a tach. I only fly about 4 or 5 minutes since I don't have a lipo monitor (should come today). That being said, I'm not going to charge my packs again until my balancer comes in (looks like mid-may from tower).

Don't get me wrong i never said there was anything wrong with going bigger! There is no feeling in RC like flying a 90 size nitro burning dragon swinging 710mm whoppers!

4to 5 minutes for just hovering is normal in most cases. just hovering around takes more effort for the blades to create lift, i could go on and on. when you start moving it around more and going into foward flight you will notice longer flight times, youre esc nd motor will run cooler also. if snd when you try nose in, try a 45 deg angle first, then slowy swing the tail into the nose in possition. it is scary it first. but it will make you a better pilot knowing how to hover in the posistion. just remember. your cyclic control( left and right) will be reversed nose in. if the heli drifts left, counter with left. or move the stick IN the direction the heli is drifting. much like a model airplane when its flying towards you.

damn, that was close!

back when I was learning on my 450 I had the headspeed down to 2300 or so and was getting 12 min flight times

Ah, my friends. The day has come. I crashed today. Nothing major. Hovering around near the ground, some tall grass reached up and got me when I lowered the throttle too much. As far as I can tell, no damage at all. I've inspected the blades, links, frames, tail, landing gear, servo horns, etc. Everything seems fine. Had I not needed to leave, I would have tried to spool it back up. Thankfully I landed pretty much in the tall grass and not on the concrete.

Now that I've joined the ranks, I suppose I'll need to really start flying around - no fear of crashing now!

Okay, I spooled it up, hovered around a bit, had an old guy come out and want to talk shop, and eventually packed it up for the day because of a wobble.

What sould I check RR community? Probably that the flybar is straight (do I just take it out and roll it on a table or what?), maybe the main shaft? I didn't crash hard, so I'm a bit confused how something could be bent, but who knows.

Looking for advice...

Most blade strikes result in a bent spindle. I would check that first.

Thanks, Chris! After some investigation as to what the hell a "spindle" is, I discovered a spindle is a feathering shaft (at least I hope that's what you meant.

I tore the blade grips off the heli for the first time and took out the feathering shaft and rolled it on glass. And wouldn't you know it - just the smallest amount of imperfection. So I installed a new one, put everything back together in more or less the right way, and now the bird is sitting back on my dresser.

Tomorrow will be the test. Thanks for the help. I'll keep you all updated (even if you don't really care!)
