rotating nose to the right

[CB]

First post, thanks in advance for any help.... Been flying cppro for a month and have repaired just about everything but I am flying and hovering all over the place...however...last night in failing light I went in nose first. Only damage was busted tail rotor somehow??? Anyway, tonight I fixed rotor and set out to fly and my Heli had the hops! Something is making it just shoot up and down with no throttle change about a foot or two. I changed batteries in Tx in hoping that would help and now the thing is just rotating nose to the right when I power up regardless of how much rudder opposite of this I give it. Did I smash the receiver? Thanks all...

p.s. Regardless of what anyone may think of the CP Pro I think it is a great tool and fun to fly. I have learned so much from all my crashes and much more from my flights.

, Trying to trick us? Doesn't seem to get your question anwsered very quick.


But I try in spite of that, 1> Servo gear( move horns while battery is unhooked and see if one has a broken tooth). (for hopping problem)

2> Rec-Gyro-- maybe the pot adjustment got knocked out during the wreck,,( Break out the book and readjust the pots on the rec gyro). (for tail spin problem)

3> Rec-gyro-- got fryed in wreck --(replace) (again for tail prob)

I don't have the Pro, But yes the CP is fun and if you can master that little beast ,,You can fly anything :wink:

sure..why listen to those with any experience.....it's your money, spend it how you wish. I'm not meaining to slam you, just the way you get attention to get help then make a statement like this boggles the mind.

I'm new too. I'm willing to bet my costs of repair and crash numbers are lower than yours and my heli costs more than yours to buy.

I'm currently doing nose in and started with tail in. I'm up to less than $20 in repairs that include 1 feathering shaft, 1 main shaft, 1 set of blades, and 1 tail fin. I started flying in January of this year.

"Good Tool" is relative...the CP/CPP is more likely an "Expensive Tool" in the hands of a beginner IMHO.

Mike/Jermo..

Thanks for posting. I will check all that out Mike and see if it helps.

Jermo, I agree with you and am tired of buying the little stuff. I am not some e-flite flag waiver, I just appreciate how much I personally have learned from the thing. Definitely ready to move on just haven't made a decision which one. What do you fly/recommend?

Sorry for the trick all, was meant to be funny...guess not. :arggg:

hehe..sorry if I came off harsh..I didnt' meant it that way.

Conventional wisdom among the posting heli drivers seems to be the biggest you can afford that's easily supported by your local hobby shop. I've seen suggestions from 30 to 50 size. the right heli for you will depend on these factors as well as your budget, flying conditions, storage conditions.. and if you intend to stay in the hobby.

My first suggestion is to visit a local field and see what the guys are flying, it's alot easier to get help on stuff that folks have. My second suggestion is to find out what kind of support (if any) you can expect from teh local hobby shops.

At the end of the day my questions/answers ended up like this.

stay in the hobby = indefinately
Flying conditions = limited, small yard, minimal help, self taught.
Budget = about $30 a week (which makes the cost of repairs critical), the going prices for a full kit with radio is around $800-$1200 up front. I don't consider the initial purchase in this decision. Buy once.
Storage= Indoors with family (limited me away from nitro since the wife is somehow ultra sensitive to the smell.. I don't smell anything)

This led me to DX7 with Trex450SE (tough bird easily repairable) with 3rd party skids (don't break easily) and fins (don't break easily), I went stock ESC/Motor, HS65MG servo's for collective (metal gears don't break as easily), GY401 gyro with 9650 for the tail, upgraded the tail to newest slider (less binding and better control), I went Generic on batteries (hextronics 3S 2250mAH 20c-30c for $32 each..I'm happy with them), did peak 3 pro charger and a blinky balancer. Function over bling.

I used the RADD method to learn to fly and invested in a good sim. I average 4x time on sim to flying. I focused on getting the heli built correctly with flying as an after thought.

Preflights/postflights are very thorough to protect my investment (remember we have about $800 up there)..

As a result I have very low flying costs (about $20 over the past 2 weeks).

I can tail in and nose in hover, next week I'll start side in.

I'm not saying what i did is right for everyone. I will say that I've tried the CP (friends) and shudder when I think how squirrely it was.

don't rush this decision, you'll be with it for a while. Quality over quantity.

Jermo,

That is pretty much the exact Heli and Tx I was planning on getting. I know that as soon as I buy it, the cp pro will be a distant memory so I am going to fly the crap out of it for the next few weeks while setting up new bird.

hehe.... I actually love the smell of my nitro monster truck. And I plan on a 50 size nitro for my next build. (wife permitting, ehem)

[Jermo]

I'd love to get a nitro heli just for the extended flight time.. couldn't stand to leave it out in the shed with the heat/cold. killed some planks that way.

The funny thig is, the people who think the Blade is so great, haven't ever flown something like a Trex or larger. :)

And compared to not flying helis, the Blade is great. Compared to better helis, it is cute. :)

Are you sure your not a bloke :dontknow :twisted: :bomb:

What are you talking about?

[Graeme]

Did you ever get this sorted out?

I didn't notice this when it was first posted, but reading your description of the uncommanded changes in altitude makes me suspect the feathering shaft.

After a hard landing, my Nexus did exactly the same thing. We spent a couple hours at the field trying to figure out what was causing it, adjusting this and that, and tweaking the radio - but nothing worked. Tracking looked fine, all the geometries were right on. But when I took the head apart, I found the feathering shaft had about a two degree bend in it. Replaced it, and she flew just fine.

BCCP and Trex are both cool in my book.

I bought a Trex SE assembled from a guy who was virtually begging me to buy his Blade CP Pro too. I told him I paid enough for the Trex and spare parts that he might want to just give me the Blade and walk away with clean hands ... so he did.

I have flown (and crashed) both heli's--the Blade more then the Trex--and I can see they are two different beasts. The Blade can be flown in smaller areas, costs less to repair, and is so light that the slightest breeze gives me a problem. Mine has a Telebee HH gyro that does a fair job of holding the tail.

The Trex is very solid, much heavier, holds the tail like a champ--and I would not think of pulling the kinds of learning stunts and experiments with it that I do with the Blade. My first forward flights originated with the Blade.

I love 'em both.

Another possibility on the hops is damaged servo gears. Power up the helo and check for smooth movement of the servo's without rotating the rotors. The gears should move smoothly when you push the stick left/right and up/down.

How's the rotation of the blades? Is there any vibration during the runup and prior to fligtht? This is very important to know as well. There are many potential causes of this included but not limited to tracking, but vibrations can rob the helo of flight stability as well.
