I just bought a brand new e-Flite CP Pro 2 heli yesterday. I charged the battery while reading the manual. I already own an MCX and a CX 2.

The dealer had offered to show me how it worked, and we went in the back lot. He had trouble. The main rotor would start to turn, but the back rotor didn't turn and the heli started to spin around and around. He stopped and told me that since I bought it, it would be best that I take it home and read the manual and take my time since he wouldn't be responsible for any damage.

I put on some training gear, turned on the transmitter and plugged in the battery for it's initial test. All of a sudden, I smelled burning, and saw that the battery started to smoke as well as smoke from the receiver at the front the heli. I quickly unplugged the battery...

The battery shows sign of damage and I bet the rest of the heli took a hit as well... HELP!!!

Dealer hasn't been very co-operative so far.

gi1mo2,


Wow, sorry to hear your story!

Like anything mass produced, there are going to be defective units, and it sounds like you got one.

If the LHS won't help, I would call Horizon when they open on Monday, they have EXCELLENT customer support, and I'm sure will take care of it for you. Just explain exactly what happened to them.

Here is their contact info...

hey va here i had the same problem with my cp pro 2 and i went to the hobby dealer..hobbytown usa..and the owner...Jack frost....pretty cool guy but most certainly the business man did not want to take the heli back taking the loss of over 250$..and in some shops at this time..300$. He did thouth inform me of contacting the manufacture and after both of us on different phones we were able to come to an agreement of the manufacture giving me another heli thru the hobby store...and both myself and frost won..neither one taking a loss because he just returned the heli back and they sent the money directly back...No problems with the new heli except needing practice to fly. It would seem that it being so new off the eflite line that a few bugs still need to be ironed out...being those few that the electronics are messed up in. At that time there is no fixing the heli...just replacing it...that coming directly from eflite.

gi1mo2- I think you need to be firm with your hobby store manager. I had the same thing happen to me (my problem was a non-functioning gryo, right out of the box) and the hobby store did not want to take the CPP2 back. I called Horizon and they at first said I should return it to my hobby store. I explained I had tried that. So Horizon sent me a gyro. But the more I thought about it, the madder I got, so I hauled the CPP2 back to the store and very nicely tried to negotiate with them. It was at the point when I said I was just going to leave the heli on the counter and pulled out my cell phone to call my Credit Card Co to have them reject the payment to the hobby store when the manager got very interested in helping me with my problem. They have treated me like a king ever since. Just don't lose your cool and get all psycho on them! LOL
Sidebar- it took trying out 3 CPP2s in the store before I could find one that did not have a problem. But in the end, I got a good one and have enjoyed learning how to hover, rebuild, hover, rebuild, etc, etc....

Just a follow-up... Horizon Hobby did offer parts to replace any that would be defective, but since potentially any electronics might have been damages, they suggested I send the full unit back with the two batteries and they will have a look at it and either repair or replace. Right now, it looks like a replace for <smokey> the blade . I did call the hobby shop and said I would keep them informed and that I wasn't very happy since it will cost me 15% of the cost of the heli to return it, and that without even having the main rotor turn over once (I did move the right hand controls with some reaction.)

So far, I'm quite happy with Horizon Hobby's offer. More later.

Hoping to fly this summer...

Hey Gilles,

Glad to hear that Horizon is taking good care of you so far...

I'm surprised that they didn't offer to send you an RMA with a shipping label, they are doing that on the DX6i radio recall, but maybe they don't on regular warranty repairs.

At any rate, it sounds good. I have had nothing short of great customer service from their service department every time I have needed it.

Hope they get you fixed up soon, keep us posted!

Glenn

Follow-up. I talked to a Horizon technician today, and he verified that indeed they received the CP Pro 2 on May 7th via UPS, but it normally takes 15 days to turn around a repair. He said he would check on it tomorrow. I've taken the time to train on RealFlight G4.5 and getting better and better all the time. This will probably be a good thing in the end, saving me crash cash. I have found a CP Pro compatible with G4.5 and have been practicing with it. Quite a nervous little beast...

More later...

Gilles

Gilles,

Glad to hear that Horizon is taking care of you, hopefully, you'll have the CPP2 back soon...

Sim time is always a good thing, and as you have found, it can help save some crash cash in the long run, both now, and when you go to do more bold stuff later on...I always practice new stuff that I am going to try before hand on the sim...over, and over, and over....lol.

Yeah, the CP Pro on G4 is a very hyper little heli, I think it's worse than the real thing....which can be good!! Maybe after all the sim practice, the real thing will seem easier!

Good luck, keep us updated!

Glenn

An update - I called Horizon support today because I haven't heard from them yet. The technician said that my Blade CP Pro 2 was still in the queue and had not been looked at yet. He said they were running 20-25 day turn around now and it was first come first serve. </p>

So I bought this thing over a month ago and haven't even seen it fly yet. I just had to pay my visa card the other day so now I really really own it. It should be simple to just exchange the box with a new unit since this one hasn't even seen air time. It was defective to start. I hope they don't spend time changing parts and trying to repair it or exchange it with one they repaired. I will then own a used heli and that's not right.</p>

At least I'm getting virtual air time with RealFlight simulator and hopefully won't crash the real thing on the first flight. With USPS to Canada, it doesn't look like I'll be getting it until end of June.</p>

Would you have had the opportunity to return your rc helicopter after the dealer's failed flight attempt? That might have been a red flag.

Dealer had indicated that he was 'doing me a favor' by doing a test flight for 'my' helicopter. He disengaged himself immediately. It was my box to take home and deal with the issues as they don't do warranty support.</p>

</p>

My blade burned up my battery the first time I connected it too. The problem was that I connected the batt wrong. I wasnt paying any attention and it just fit right together!!! Be careful and get new connectors that only connect one way!

I got my Blace CP Pro 2 back today. Yahoo!!!

It's a new unit. The comment on the document attached is "2-in-1 unit failed. Shorted out and damaged the receiver, motor and battery. Replacing heli under warranty as well as the spare battery included'.

Everything good except that the spare battery wasn't include, but a call to Horizon quickly solved the problem - a new battery is on it's way.

I charged the battery and followed the book on testing the controls (motors disconnected...), just to be certain. Put on the training gear, swallowed twice and took it outside with the settings in the proper position on the transmitter. Turned on the Transmitter, plugged the battery and waited for the lights to go on, throttle hold off. I was ready.

Throttle up gently, main and tail rotor spinning. Throttle up more and the heli took flight. With my training on the simulator I was able to hover, but it is very very sensitive (even with Dual set to LO). But I was up and landed safely, sometimes harder than others. I did manage to land a little slanted and a blade tip touched enough to tear the cover a bit. Nothing that scotch tape couldn't fix quickly. I'll be looking for replacement blades if anyone has recommendations (I'll look at various posts).

All and all, it's great so far. I will keep the training gear on for a while though.

Not sure if there is any adjustment for this, but I can hover for a few seconds and suddenly, the heli decides to go off in a direction, and I have to force it back - no wind, no stick movement.

gi1mo,

Glad to hear that you finally got a brand new heli back from Horizon!

Sounds like pretty good service, less the backup and long wait...they really do a good job in the service dept there, at least they always have for me...and I can imagine that this time of year is extremely busy for them...they probably barely had time to catch their breath from the DX6i recall...

Not sure about the heli drifting off....are you out of the ground effect/rotor wash yet (at least 2 feet off the ground)? If not, that will play games with the heli hovering, it gets messed up in it's own wind, basically...see how it goes when you have more time/practice on it...

Glenn

gi1mo- Good luck with your new heli! After my last CP Pro 2 crash I decided to give it up and opted to buy a new Align TRex450 Pro. All Ican say is that I crashed every single flight (hover)with my beloved CPP2, even with training gear on. I just never could get it what I'd call stable. Now, after21 successful hovers, with no landing gear on any of them, I am ready to move onto nose-in hovers and basic forward flight. The 450 Procan be made<u>that </u>stable! I really love and appreciate that the CP Pro 2 got me into this hobby, but it nearly took me out too, since I spent more on repairing it than the 450 Pro costs. But I sure learned a lot of the basics of helicopter building and repair from the CPP2 too, so all is not lost.

As far as the sudden movements you are experiencing, I noticed some of that action with my CPP2 also. I just wonder if there is some flexure in the construction which we can't see really well, and the heli takes off into an unanticipated direction because of it. I could easily flex the head area of my heli, so despite all the concentration on perfect setup, accurate controls, etc, the bird seemed to have a mind of its own.

2 thumbs up for the guys at Horizon. And if you need other heli parts, etc, the guys over at HeliDirect have treated me like a King on warranty issues and finding ways to ship things FAST!!

Cheers, and happy flying!

Tony

I love My Cp Pro 2

Have you upgraded the Gyro for it? I have noticed that it is very jerky. Perhaps I have to adjust the one on this heli? I haven't broken blades yet (thanks to the simulator), but have nicked them slightly (just a little tear on the platic covering). But, I had to land harder than expected because the unwanted sway, and the landing gear broke (even with the training gear - which prevented the heli from tipping to it's side).

I also got some curious behavior yesterday. The heli would hover and then a higher pitch main motor sound and loss of power and the heli would go down. I would restart and it went up but a few seconds and then the same sound... I took the heli inside, inspected it, tested while secured and got the same behaviour. Unplugged and went away so as to stay calm and when I returned and plugged the battery in again, it was fine. I wonder what happened. Anyone experienced that before?

I love helis. Now how can you help me love my CP Pro 2?

Gilles

gi1mo2,
Your first CPP2 flight sounds very familiar! I had the same "drift" butmine wasn't overly sensitive, in fact,my right stick commands were very mushy. I was using 1/2 to 3/4 value stick, and holding it for a second or too, to get it back to level (and that was after I got the trims set.)My day was also ended bya slightlyoff attitudelandingand the<u>grass</u> tore one ofthe rotor blade covers. I don't really care for the idea of repairing main rotor blades, and I certainly don't want to have to do it after every landing in grass! So, I ordered two sets of CF blades, the CF tail fin set,and the FS One simulator.Thendid some research and development while I waited.
Here is what I did.
First, I modifiedthe throttle/collective axis on the stock TX, bysanding the teeth off of the ratchet gear, and bending the metal ratchet lever to get the resistance set the way I like it. (Some people simply remove the metal piece, but that made it way too sloppy for my taste.)
Second, I found that several posterson RCU, had issues with the collective pitchnot matching the settings described in the manual. Most were finding that they were getting +4 to +5 degrees at half stick out of the box.Since this check wasn't part of the setup instructions in the manual, I assumed that it came out of the box with the set up shown in the diagrams. WRONG, mine was+4 degrees, so I dialed that in, andchecked thatitmatches the curves shown in the bookin allflight modes.
Third,during my initial setup I had a lot of trouble getting the CG forward enough for proper balance, andstill secureing the battery tight enough to keep it from shifting around whenI tilted the heli by hand.The velcro and rubber bandsthat came in the box just didn't seem to do the trick, so, I got some better velcro andadded some poly bands to help secure the battery. It was still a bit too wobbly but good enough for testing, and I moved the horizontal stabilizer forward about 1 inch to helpwith the CG issue. However, I still wasn't satisfied that these issues were resolved. I ordered the CF tail set, hoping that it would be lighter than the stockset. (It turns out that they are about the same, but I like CFso I put them on and will save the stocks for spares.)I alsobought some Scotch "dual lock fastener" to take care of the battery securityissue. The piece attached to the battery support is cut to length of the support, the piece attached to the battery is the length of the battery, and then I attached asmall piece to the 2-in-1 input connector. I attach the battery with the leads facing forward, and the rear of the battery aligned with the rear of the support,then fasten the connector to the frontof the battery. I now have everything stable up front and have 1 degree nose down on the CG.
Fourth, I spentquite a bit of time with the FS One simulator, and I can assure you that it helped me brush upmy computer skills andexpand my 4 letter vocabularywhile trying to get it to work!! I did get about an hour or so of practice, and that probablyhelpedme refreshmy R/C skills as well.

I have only been able to fly my CPP2 twice after the adjustments, but it is definately a different machine! The first time back,I needed to make some minor trim adjustments, but I kept it airbourne for five straight minutes. The second flight (last evening) was actually pretty boring. Even with some light gusts of wind I was able to keep it in a tight area, it hovered "hands off" for around30 seconds...twice.At the end Itrieda pair ofspot landings, and only missed by a couple of inches. Next time out, I will be working on sides in hover.

I hope that this helps, and keep searching the threads, there is a lot of good advice around here!

Logan</p>

No need to really replace the gyro at all, I have about 30 flights on my cp pro 2 and its been a blast. Although I have been flying for about a year and a half.

The tail holds very well, a little bit jerky coming out of piro's and stall turns but nothing I can't handle. Plenty of power with the main motor.

On the pitch curves mine did come shipped +5 at midstick, not sure why it was like this but when the first Blade cp came out thats what they reccomended for midstick pitch in the manual.


I have only had one crash in about 3 weeks, but that was when I did a loop and didn't pull out fast enough and it hit the ground. broke the skids, canopy and frame, that took alittle over a hour to rebulid, but was flying shortly after.

overall very happy with the cp pro 2

Guys,
If your CPP2 is acting strange, like motion you didn't ask for, check your blade dampeners.  My brother inherited my CPP2 the other day, and he discovered that after only a few hovers, the O-ring dampeners were badly worn.  And it required more shims too.  After he made the head stiffer with new O-rings and shims, he reported that the heli flew MUCH more stable, with no more side to side or bobbing up and down action.  There had only been about 40 minutes of flight on those original rings and shims.

 I also had a really hard time moving the CG forward on the CPP2.  Could not get the battery forward enough and still get canopy on.

I think the stock gyro worked fine and was pleased with the tail action.

As far as blades go, I went straight for the Sym Carbon Fiber blades after tearing up the stock ones on my first encounter with a tree limb, and never had any more blade problems.  They are really tough and perform so well.

Cheers!

gi1mo2- I can't get the PM to work. Sorry.

Unfortunately you have to by the dampening shims and the spindle set (with o-rings) separately I believe.

All these parts are located very fastidiously in each main blade grip. See your manual for the parts layout. There is also a thrust bearing and stepped washer in there. It's a real pain to take apart and reassemble. You will need TWO 1.5 mm hex drivers to do it.

Tony

     I don't know how the carbon fiber blades would hold up against tree limbs, but I did have the "opportunity" to test them against grass today. I didn't get far enough over the pavemment when I set it down, and since the edge of the pavement is sloped, the blades dipped into the grass to about a third of way in from the tips. It was a soft landing, so the RPM stayed high while the mulching was in progress. With my (limited) experience with the stock set, and after reading many posts from others, I would say that this would have shredded the covers off of the woodies. But, a couple of wipes with a wet paper towel and the CFs are like brand new!
     Todays session was also my first without the training gear. It is now .44 degrees nose down CG, so I spent most of the session working on the new trim setting for that, and some roll trim adjustments (which I didn't expect.) I did get enough air time to notice that it is quite a bit more responsive than it was with the gear on, so I will need to work on my timing for a flight or two before I move on.

    tbosco, $10+ s&amp;h seems like a steep price for 5 cents worth of O-rings! Do you happen to know what size they are? I will gladly look for a supplier and share the info.


Logan

Logan-
Nope, I don't know the size. Notice that the o-rings come with a rotor hub assembly. You may also need to add 2 shims per side to stiffen it up a bit. They are available separately.

Tony,
    I know that we can get the O-rings with the hub and spindle @ $10 a set, but you said that your O-rings were badly worn after just 40 minutes of flight time, which is only 7 flights (6 if you drain the battery.) That could get expensive in a hurry ($15/ flight hour), not to mention all of the "spare" hubs and spindles that would be collected. I am very confident that I can get that cost down to around $0.15/flight hour for all of us. Maybe even help to avoid a crash or two (mine and other RCU members) due to worn O-rings??  The shims are 2 bucks for a pack of 8, which is a pretty cheap upgrade (if you need them) and they shouldn't wear out, so no issue there.
    As it is right now, my heli only needs two things to fly very well... fair weather and a good pilot!! I want to keep it that way! She has to wait for me to decide when the weather is fair, and she has to wait for me to re-learn my flying skills, but she wouldn't have to wait for O-rings! I will order the hub/spindle set to get a pair of new Os, and I will post what I find out about supplies. If you are right about the wear issue, we are going need a lot of them.


Logan
</p>

Logan- I got the info from my brother, who I consider to be nearly an expert flier (I'm a beginner). He dissassembled my blade grips and discovered the lack of shims and worn o-rings. I will qualify my statement about the worn o-rings with this- I had quite a few wrecks with my CPP2, and had to replace the feathering shaft (spindle shaft) a couple of times, so the advanced wear on my o-rings may have been crash related. But all those crashes still occurred in less than an hour of combined flying time. I never could achieve very stable flight at all with the CPP2, and therefore the wrecks. But my brother says the instability was due to the lack of shims and bad o-rings. If I get more info on o-ring size, I'll post it.

Keep us informed with your findings, and thanks!
