I started to fly on a Raptor 50 Titan in 2008. Rebuilt it once fixed it a couple of times and it was great.

Thought I would build another one to cover the down times and I did. Flew great, 0 crashes and sold it to by the SE.

Many gallons later....

When the Raptor SE came out I jumped at the change thinking Yes... we are keeping up with the pack of A's.

Then came the dust...four flights after the maiden, with an aluminum fan installed, I had to auto rotate.

On inspection I noted the main gear in poor condition as well as the bolts sheared off the fan. Major dust present, and then I read some of the posts on the topic. I talked to ACE and they told me about the problem with the main gear.

I was advised by ACE to revert the main gearing to the old version, which I did as I had many parts on hand. There was never any talk about changing the frames, but then I didn't work for Ace.

More dust.... Not to worry as ACE told me it would work. Now I did install an OS55 in the SE so I am not sure if that is one of the problems but.....the TT53 comes from the factory.

So the other day I go out and fly a couple of flights and to my dismay the same thing happens dust and the clutch coming off the fan. Pulling everything apart I notice a more than average movement in the clutch bell fore and aft.

Now I have ordered all the parts to return it to the original SE version, but this will be the last time. I intend to put a UK Fan on it, as all the raptors I ran had the ALU fans on them so I can not attribute these issues to that.

But what my feelings are is that perhaps the OS 55 is too powerful for the main gearing setup or........the SE was just a Band aid to the new version of Raptor with more pitch and that Thunder Tiger is just trying to hide the problem with their product in order to try to defer their market value which is low right now.

I personally will not order anything from Tower Hobbies as they only use UPS which means 100.00 on the bill no matter what dollar value you order comes to when shipping to CANADA Eh.

I think Thunder Tiger dropped the ball on the SE and I most certainly will not purchase the much touted but misAligned X50. I feel after dealing with all these problems they should send me one for free....LOL.

I am currently building a Fury 55 which I hope lives up to its name.

My two cents on this topic........for what it is worth.

Well since I don't work for Ace anymore I can pretty much say what ever I want. I was the one who helped the gentleman out from Canada. The problem was issues in materials in the main gears, frames and pinions. TT knew this and told us to shut up basicly. I tried to do my best and even replaced an engine and a bunch of parts many, many times. They knew what the issue was and just wanted us to sweep it under the rug. So there is it if you see this issue with the dust stop flying for your own saftey. Call someone make a big big stink about it and they will give you back your money or replace your bird. Don't let the distributors push you around they will do anything to get you off their case. email thunder tiger directly many many times until they respond they will cave in trust me.

Well I don't know how they could not be aware of it since the whole thing started there in the UK. They know about it there just trying to brush you off. If TT does not respond I will PM you with an email address to contact.

and the clutch coming off the fan
I think this is an unrelated problem that has been seen in the past. In most cases the screws were just a hair too long, (or holes a little too shallow) allowing the clutch to move around on the fan while slowly fatiquing the bolts. Shortening the bolts a few thousanths should remedy this.

As for the gear, bummer, hope TT gets it sorted out before they lose what small Raptor following there is left...

duke714, thanks for stepping up and helping us out. Hope your having good luck in the job market.

I'm still convinced the problem is also related to the pinion, Thanks for putting it out there Duke714, nobody else would ever confirm there was anything wrong with the pinion... I'm still getting great performance a year later with mine with the old school clutch stack, but with all this political crap, I'm about ready to strip all my gear and go with something else for my primary 3D beater.

I never would have dreamed putting the old clutch stack from a crashed bird in my new Raptor would end up being the final solution when I decided to give it a try about a year ago when my issues first showed up.... its quite sad, really...

two kids? how'd that happen? time to zip'm up!!!

Here is the answer to an email I sent that I got from Thunder Tiger in Taiwan. Still doesn't solve my problem. I am going to De-Raptorize my fleet.

"Thanks for contacting us. After we received the response of the gear issue from end users, we spent a period of time investigating into the issue though we did not think it affects. Finally, we found the cause of the problem came from the plastic ejection process of main gears. Then we modified the mould and made new main gears that conformed to specification. We had helped end users resolve the issue with the new main gear. You can refer to the post written by "Airwolf2009" on page 8 of the related discussion on the forum, Runryder. We had also sent around 50 pieces of new main gears to Ace Hobby for after services at the time.
We have been doing our best to help and serve our customers. We do not know why such an untrue rumor would come from an ex Ace employee. We have never told Ace to cover up the issue, either. We will take action to investigate the cause and effect about this. If we want to hide the truth, we will not reply the mail."

Believe it or not......

that response is enough for me too, I'm stripping my bird and getting rid of it... I had sorta been hoping TT would man up and release a fixed pinion. The fact of the matter is I figured out you could get around this issue by running the old clutch stack, new main gear or not, so that tells me the new pinion is defective. They say the problem was found on page 8 of this thread? BS!!! I found it on page 2 when I swapped the old clutch stack and pinion from a crashed raptor, and voila! problem solved!. I tried the same pinion after I got it back from inspection with a new main gear, and guess what... wore out that gear noticably in 1 flight.

I am convinced that pinion is primarily at fault, and will mess up any main gear you put to it.

I had a look inside a scale heli raptor v2 its had about 5 flights looking close at the main gear i see a little bit of powder i think this is due to the gear been new including the heli,so the pinion on the titan se could be the biggest problem,if tt has changed the main gear does anybody know if the pinion has been changed

As noted above, Thunder Tiger acknowledges that there was a difficulty in the production of the part, and has modified the process. Since we are now the service center for Thunder Tiger in North America, we'll be able to take care of parts requests. Parts are currently available.

As always, if anyone has a difficulty with a part or complete unit, they can send them to us for the needed service/replacement, depending upon the issue.

I got two emails as well. One from Thunder Tiger and one from Great Planes. In the Thunder Tiger one they requested photos as datidun.

The one from Great Planes stated that they were trying to find the "new main gear" that TT sent out. This is how it read:

"First I want to thank you for you patience in this matter. At this point parts and product are still in transit to us from their warehouse in California as well as from the overseas factory. This transition is only a matter of weeks old for us to take over the distributorship of their products and it will take some time to get everything here, sorted and placed in our warehouse. As you can imagine, this is a huge undertaking at a very busy time of the year for us and it will take time to accomplish.

We have heard back from Thunder Tiger in Taiwan concerning the problem with the gear in this heli. As mentioned on the RunRyder thread, they have made an improved gear that solves the issue. At this point Thunder Tiger is trying to locate the package of those improved gears in the California warehouse. They have promised to send those to Hobby Services as soon as they are located. Once we have them, we will send one out to you immediately.

Again, thank you for your understanding in this matter."

So it seems that Great Planes does not seem to be on the same page as Hobby Services or Thunder Tiger and perhaps Mr. Baxter should talk to them if what he is saying is true.

Bottom line is they had a run on some kits that were defective and they should replace the product. I would be happy to send what remains of the complete kit to Hobby Services for replacement although I doubt that would happen.
