Exclamation fiberglass f35 twin 70mm

hy I'm new in this forum and almost in the rc world I'm building my first plane and need some advice by much more expert person then me .
the plain is a
composite f22 raptor Twin 70mm Fiberglass EDF Jet (ARF)Dry Weight: 1420g I'm going to fit it whit
2 Alloy DPS Series 68mm EDF unit with 3580kv Motor 238g - 1000watt Max Thrust: 1.7kg(trust between 1.48kg 2 x 2200 30C 4S in parallel 62.56Amps 49,500 RPM to 2.2kg 5s)
2 Turnigy dlux 100A SBEC Brushless Speed Controller w/Data Logging 96grams
Turnigy R/C LED Lighting System 35g
retracting landing gear about 150gr
reciver- servo- linkeage about 200gr
total approssimative weight 2288gr
my question is what battery I should use in it ?
I was thinking to go whit 4s to be safe whit motor and esc
but I'm undecided how many AMp and C rating
I think the best would be or 2 4s 3300 40c or 2 4s 2650 20-50c
what scare me is to add to much weight to the plane and not to be able to take off and fly the plane
doing some approximation I have betwen 672gr and 1.112 kg of spare trust push subtracting the weight of the plane whit electronics whit out battery
please help me I'm stock on the last tink that I need to buy

All the other stuff is a bit over my head, but I'm wondering where you're going to fit 2 EDF's in the single engine F-35? Is it an F-22 maybe? As long as your batteries are rated above the amp draw required by the motors, they should be OK. You just have to choose how much mah to balance how heavy you're willing to make it versus how much flight time you want.

maybe I'm missing something, but an F-35 is a single fan with a single outlet in the tail. unless of course you are talking about the vertical lifting fan of STOL model.

Sounds like the battery can handle it. Do you have a link for the plane? I just had a deal fall apart for a 64mm F-35 and I'm looking for another bigger one.

thank's I went to check the web site where i bayed the plane and it's a composite f 22 raptor you give me the hint talking about the vertical lifting that the f 35b is capable and the f22 raptor not .
there is always something to learn specially for a novice like me that's why I joined this forum
thank's again
what you think about power setup?

So F35 you know this is in NO WAY a first RC model - right? Just hoping that this is not your trainer - or it won't matter what power system and battery you use.

Sorry to be blunt but this will be a rough start for you.

no no it's not my first model i already flew a p51 mustang a f117 stealth and other couple foamy edf jet . this is my first fiberglass kit sorry for the mistake but it's a f 22 raptor and not an f35 so dealing whit weight trust flying time is a little worry for me and that's why I cant decide what battery fit best for this bird and motor

What does the manufacturer recommend for battery? Do you have a link for the plane?

I would try to keep that as light as possible. So the 2200-2650's 4s max. You will want some competent cells 30-40c.

I totally agree whit you 2650 sound a good compromise between weight and power I have this in mind
14.8V 4S 2650Mah 30/60C sky lipo eBay 43$ or maximum turnigy Nano-Tech 3000mAh 4S 14.8v 25C-50C 47$ ebay
what do you think?

I prefer the Gens Ace from Hobbypartz.com. I have had excellent results using them. Very happy....

One other factor - you may want to wait to get the packs to see what weights are needed for balance.

I think I will do like that I will wait the model to arrive and when I have all the electronics in it I will determine the weight of the battery for balancing
doing some calculation I have between 600 to 1000 gr for the 2 battery so anyway I have to stick whit 2650 3000 milliamp 4s I will check the battery that you suggest
thank you for the advice nice to meet you
my name is Mike too
