That looks sweet, like the color combo.

Just curious. I put half down. Do they Make you pay the the rest before it leaves thialand or once it makes into your port? I'm getting worried with all this bs going on.

Skunkwrks

It usually when the ship get into port you paid the other half , you got time to shake the tree for some more money. Lol

Sorry I think the typos made that hard to understand lol. I'm more just worried about losing 100% if ww3 breaks out in the next few months, so atleast if I pay only once it is in USA, my risk is less of China bombing the ship lol.

If it gets lost I'm only out 50%.

I have full funds ready for this I'm just the nervous type.

I like my cheaper servo choice. I'm still up in air on turbine I have kingtechs but at one time I had a jc rabbit and it was very nice. I always thought swinwin was Chinese junk? The first time I saw one is they were shipped with the hsd foamy jets and those that came with that had the stinch of hobbyking. Interesting times when spektrum has found its way into turbine jets. Clearly I'm out of touch

If WW3 breaks out, I doubt you'll be overly concerned about getting this jet. I'll be packing up the RV and getting the heck away from any city and heading for the hills to defend my family.

Seriously though, CARF will take care of you. Once the boat gets here and they're ready to ship from the US, your rep will contact you and you'll be able to pay the balance.

Carf might take care of current customers, but apparently they don't want new ones too bad. See Mig 17 thread.

NO! I have to fly this jet before the worlds ends!

Man RCU has gotten soft. You're supposed to say something like if I cant afford to light 6k on fire, I shouldnt be buying this jet. It was a bad joke, Im more worried about embargos and sanctions, Id rather be out 3k than 6k for sure, its nice to know that it gets to US first, once here I think its pretty much guaranteed.

Its nice to know carf would take care of me, back in the day some vendors put 100% of the risk on the customer, and sometimes they wouldnt even finish the jet and want more money to keep going (FlyEagle).

Ive been sending money grams to people in ukrain that I know to help them out, I feel like a big fat American.

You're probably right about flying before the world ends. I'd have the Max packed up with me!

Question for the Carf Rebel pilots. I've been flying the Pirotti Rebel (2M) since roughly 2016, I just noticed the rates posted on the Pirotti manual are about half of the rates in the Carf manual.

Anyone know if this is due to testing or design change?

Anyone have a Rebel Pro flying with the new fuel tank fittings that CARF is now providing? I'm in the middle of assembling my Pro and it seems the the main fuel fitting although plumbed for 4mm ID fuel line, the actual nipple inside the bung is only 3 mm ID, worse, the vent fitting only has 2.5 mm ID. Is that going to be adequate for a 210 turbine? I was planning on using 6mm ID for suction and vent lines.

My Feedback: (20)

No, IMO the IDs are not big enough for that size turbine. I have changed many fuel systems to enlarge the IDs to suit my understanding of higher flow and lower pressure prior to the pump input. I got my understanding from Oli's fuel system articles.

https://www.ultimate-jets.net/blogs/...considerations

I get laughed at but here are my rules of thumb. 1/8" ID for 45 to 160N. 3/16" ID from 160 to 210N. 1/4" or 6mm ID from 210 and up. My biggest has been 320N. These IDs are from the vent, through the clunk, to the air trap, to the pump input. Just my way but I see lower PW. no bubbles, and don't have speed low flameouts. Just my way but it has worked for several years.

Good luck.

I pretty much agree with Gary. If your tank is the 5L tank (I believe the Pro and Max share the same tank), those fittings should be for 6mm from the factory. That's the tank that is in my Max and everything was definitely 6mm. Have a look at my thread if you'd like;
CARF Rebel MAX - Build Thread Posts 1-14 shows mine and discusses exactly this.

*EDIT - I just noticed you were talking about ID. Honestly, that I did not measure. 6mm lines work perfectly. Also, I'm running a 235G4+ in the Max and the OEM stuff is working nicely. I was going to go with an 8mm vent but "the boys" talked me out of changing it. The 6mm vent is definitely adequate.

For those who were out of luck like I was on getting replacement tires for your rebel on airtech germany high speed wheels, I have retooled the tire and have been


molding them. They are 100x22 HS. If you would like a set, PM me. They’re $75 a pair shipped.😎

Skunkwrks

Good day guys, went and measured the fuel supply ID of my CMjets tank it 4.8mm ID OD 6.6 mm. The vent nipple ID is 4.98mm and 6.99mmOD on the nipple with 6.35mm on the tube.
Seems like Carlos has the same guidelines as Gary does, guess after building many custom tanks he has learned a lot and is worth the $50 spent compared to Carf specs.

I have no idea, but I would go with CARF. Honestly after a couple flights Ill probably use carf high rates for my low and then max throws for my high. Big floaty jet is like a 3d plane from what Im seeing. Of course you dont want to go full beans then yank out at high rates but at our level we know better. Though Im sure the jet could take it.

In terms of fueling, I go with high flow everything even on small jets. Regardless of turbine size, the high flow benefits from fueling and defueling keeping pressure off the tanks. BVM high flow clunks, 8mm anti static line all around, depending on tank geometry I might use the biggest tygon I can for plumbing but for this tank I think ill go with 8mm anti static inside as well.

At the end of it all, the line going into the turbine is what, 3mm? Thats the bottle neck while running there but having everything be as free as possible has always benefited the tanks and the pump PWM. this jet having only 1 tank is going to be easy to plumb, plus no air system. Might be the simplest jet Ive ever owned.

Kenrico

I got the earlier version of tank with my pro, and went all out with BVM high flow stuff 8mm all around including uat.

Thanks everyone. I wish I would have looked at this closer before I spent the money on the CARF tank, especially since I ordered the CM Jets smoke tank. Anyway, I know it might be overkill but I just ordered new 8 mm (6 mm ID) fittings for everything and will modify the stock tank to use them - better safe than sorry.

smcharg

My Feedback: (1)

You aren't wrong there but, remember, the pump and turbine fittings are 4mm on the 210. 6mm is already larger meaning more potential flow from the tank to the UAT and UAT to pump. Certainly you don't want a vacuum but, again, I have the exact same tank (assuming the 5L CARF tank) in the Max running a 235 and there are zero issues pertaining to this.

Also, Dirk from Pacific RC literally said with my 235 "don't go crazy with that 8mm stuff"

dccatl

My Feedback: (1)

Yep, thought of all that, just peace of mind for me, never heard of a problem using too big of fuel line, and my UAT is already plumbed for that size as well as my overflow vent. Thanks again for your input, I appreciate it.

Viper1GJ

My Feedback: (20)

My rules of thumb are based on getting slower flow, lower pressure, and less chance of cavitation prior to the pump inlet. I keep the vent size big and I step down the ID size to connect to the pump at the pump inlet. I think it is less stress on the pump resulting in lower pump PW. After that it's up to smarter guys than me for the pump design and flow to the turbine. Been working well for me many years.

Being hopeful on getting mine by July. Im going to start gearing up. I was thinking of using the 7950TH servos I posted a while ago, but it looks like people like MKS servos? They are very well priced and very powerful and fast.

Do you guys trust mks servos? Ive used hitechs never had an issue, seen many jr 8911 having issues. Seems every brand has someone with some issues. Im not a brand fan boy, I just stick with what I know works.

I am strongly considering MKS now.

I guess I have been called worse LOL, I used pretty much MKS exclusively….I do have a couple of jets with DITEX (with telemetry)…for me I used what work I have been burned a couple time trying other brand…and cost a plane and a bunch of replacements servo’s.

essyou35

My Feedback: (11)

Recommendations? I went off what some others said. Im not seeing a point in all 8 servos being the same, flaps can be slower but should be stronger, same with steering.

Dansy

My Feedback: (53)

The 777+ are nice not too noisy….maybe a 550 for the steering….I will look once I’m home, I don’t remember which we used in the one I build….(still flying 3th seasons)
