so I want a Carbon frame but WHICH ONE????

[concept1]

so for now it looks like I have 3 choices on carbon frames. I want to use A123 cells 8-10s so the stock Gaui frame is out!. and at $199 I like it the least. I just don't like the battery setup.

the rotorworkz frame looks real interesting and they range from $129-169 , it will easily take any battery, any pro's or cons on them, G10 and carbons

also their is the custom heli parts frame which really is the ugliest but it maybe has some real benifits. but for me one negative, I don't want to use the 9650 servo's so can the cutouts be enlarged to use the jr 821's? I really do like the direct servo linkage to the swash. and it also should easily take any battery config. and priced at $149

so any other pro's or cons on these frames? also I have not seen parts replacements on them will their be problems on getting partsfor either frame?

their is a 4th frame Xmseller has one and really it looks nice but not real sure of the quality. he has stuff all over Ebay and has had a past reputation or poor quality, but Ihave heard some goodthings about his stuff also.. so just not sure????

I have the custom heli parts frame. It has a single width frame design which I guess is stronger than the split width designs. All the cnc bearing blocks are from the Gaui carbon frame and readily available. 9650 servos are an added cost, though some other similar sized servos might fit. 9650s gears are nylon and prone to self destruct in a crash (but cheap to replace). Larger servos won't fit. This is a very strong frame and very rigid. My Hurricane has never been smoother to fly - can't comment on more demanding (3D) flying because I can't do that yet. A bit lighter all up than my plastic frame set-up.

A rather serious crash due to radio failure caused very little damage to the frame (the bottom plates that hold the landing gear pulled out and suffered a little damage but were repaired and put back in). The Trex 3D landing gear is almost indestructible - if I was using the Gaui landing gear it would have probably broken instead of the frame being damaged.

All up this is a very nice replacement for the plastic frame! I like it.

thanks ianjh123,

that confirms my thoughts that it would be a much better choice over the stock Gaui Carbon. which leaves the only negative your stuck using the 9650's, althought I would think it could be modified to use std servo's. do you have any pics of your setup?

[ianjh123]

This is the part that will stop you using larger servos - the aileron servos. Also a pic of the heli complete with electronics. The frame allows a very tidy install.

[concept1]

thanks,

so far I have my first choice is the rotorworkz G10 frame, Looks and price @ $125 not a bad deal, But I still can't rule out the custom heli frame. do to the weight savings and the geometry change. just not sure I like the looks (seems so skinny) the stacked just looks better but adds weight and not sure it adds function

I have gotten quite a few thing from XMSeller, also http://www.cnchelicopter.com/servlet/StoreFront for my T-Rex and recently the CNC tail set up for my Huri. He has very good service and the quality of everything I have received has been good, better than some MicroHeli stuff I have gotten in the past and at a better price. I would not hesitate to buy from him again. :thumbup:

[slo_dave]

I just bought used hurri that has the CFP frame.
I'm in the process now of stripping it down, checking and rebuilding.
It is one SOLID frame, very strong and very light. Not being able to utilize full size servos makes it not the clear winner but if you have some 9650's or Hitec 5245mg's (as I do) your good to go.
RH is out of stock right now though..

[CompuFoil]

One benefit of a stacked frame is in a bad crash, normally the lower end of the frame breaks. You would end up replacing a full size side instead of just a lower half. More work and expense...

[ianjh123]

The custom heli frame is made from 2mm carbon fiber. I had a pretty bad crash with almost no damage to the frame. I'd like to see the crash that breaks one of the side frames! Can't imagine there would be much of anything left.

This frame is very similar in design to the super kit frame in my Trex 450, which has survived much abuse (learning) over a couple of years without a scratch. I think it is a proven design. As for looks when the canopy is on and it is in the air, it will make little difference.

All up I think any of the carbon/G10 frames will be better than the plastic frame, but even a year of flying on the plastic frame never put me off this helicopter.

Be careful with the cnchelicopter parts. My brother has a Lepton and all the cnchelicopter equivalent parts look about right but are different enough that you have problems (like the cnc elevator assembly not working with the Gaui elevator arm on the Hurricane).

Only 2 things would have made this frame better for me - use of bigger servos and G10 material.

[vicrc]

What is the weight saving on the CHM carbons? I really like the look, very very simple and I don't mind changing out 3 servos as it also saves weight.

[ianjh123]

This pic shows the assembled frame - not sure what the weight is for a plastic frame with the same parts.

All up I went from a plastic frame with jr DS821 servos and a z20 (with fiberglass canopy) to the custom heli frame with 9650s and a z30 (with plastic canopy) and lost 105g. Not bad considering the z30 is heavier. Not sure of the canopy weight difference.

If you want to go 10S A123 (or even 8S) I think your best option, by far, is the Custom Heli Parts frame. This is my 10S A123 Hurri setup with the CHP frame and it works great!

Mike,

thanks I saw your 10s post, looks good! now I am back to 50-50 on the CHP and the Rotorworkz. my biggest fear on the CHP is just busting off that front battery holder, what are your thoughts on that? for 8s I think the CHP would really work well, but so will the Rotorworkz. if I could run STD servo's I would jump on it. I believe though you can use one of the Hitec mg mini servo's also on the CHP though which would be nice.

[oppie]

Mike how does your Hurri balance? Are you using the long boom?

Short boom. Slightly nose heavy although I'm planning on getting the CNC tail which should get me CG'd just about right. I had it perfect with the Scorpion 3032-10 but since I mounted the Neu (slightly bigger) it whacked my CG a bit so now I need more on the tail-end...For now I'm just living with it!

Don't worry about the battery tray -- you'd really have to pound it hard to do any damage. This frame is tough stuff -- not some wimpy thin CF! I already pounded mine and just broke the bottom skid mounts which are super simple to replace.

[vicrc]

ianjh123, thanks for that info. Wow that is possible weight difference in lipo vs a123?

Mike Whose CNC tail are you using, Heli Direct?

I don't have the CNC tail yet but I'm thinking about the Gaui one. I'm not enamored by the HeliDirect stuff to be honest with you although I did just buy some hardened shafts and the carbon tail boom from them (with outrageous shipping charges I might add!) I wish Kasama did a CNC head/tail for the Hurricane -- that I would buy in a heartbeat! :drool:

Hi Guys/girls,

Wait for it, I am in the process of fitting a complete TT 30/50 tail to my hurricane, should finish it when I get back home tommorrow! The tail I am using comes from a company in Taiwan. Hobby Taiwan or HT Carbon tail unit. It is made for the Thunder Tiger helis, but fit the Hurricane tail perfectly. The only modification required is to cut the tailboom shorter and use the offcut (split in half) over the boom to get the Hurricane tailboom the same thickness as the TT boom. Will post photos when I get back home.

I have been flying mine with the CNC tail from HeliDirect. Mine flies beautifully. No issue with fitting the Gaui tail output shaft to the tail case at all. The extra weight in the metal tail unit helps out with the CG when I flies the 3300 TP/FP packs. I also upgraded mine with the CNC seesaw. That was also a perfect fit. The side to side play of the plastic seesaw is now gone.

Outrageous shipping charge? All my orders had been free shipping. The only time I have to pay was when it was less than $100, but then the shipping cost was only about $5. The parts arrived in San Jose in 3 days.

I ordered more than $100 worth and it cost me around $10 for shipping. How do you get the free shipping deal? I'm in San Diego, CA...

I didn't do anything special. I had to pay $5.00 for shipping when I purchased the metal tail unit in December. The package went through USPS priority mail. When I ordered the motor and a few CNC parts from them a few weeks ago, the web page only ask for $1.50 in insurance, then it went out on FedEx ground. It took a week to get to CA, but it was raining so much up here therefore I did not care much for the delay.

Mike what do you mean you are going to get the GAUI CNC tail, I don't see one on the Ready Heli site? Where do you see it?
