Unlike the 3400G, the 3500 can't or shouldn't take 6V. Looks good Sokal. Head looks nice and beefy. Should be a nice machine.

very nice build

Are the sonix head and tail a better design than the stock b400 parts, or are they pretty much the same, just in aluminum.

yes a diffrent design

the mixers are in line with the flybar that way the fly bar cant bind against them like the 400 head

also the flybar is abut further separated from the blade grips wich give more cyclic deflection.

lot of othe design diffreances.

one draw back is the ball links even tho the 400 ball links are suposed to be one way. but will allow you to use half adj. the rex head links will only go in one way so full turn adj wich mean to do tracking you may have to adj more than the pitch links. that means blade balancing is very very important.

Default stock vs cncheli main shaft

both are the same length/size. the bottom holes match. the top holes dont reason is for the cnc head. had to move the hole to allow the flybar clearance in the rex style heads. both shafts will work in stock and cnc frame. and stock and cnc heads. you will have to mod the stock shaft my grinding some shaft off the top to allow the clearance for the cnc head. the cnc shaft is a solid shaft un like the hallow stock.

will keep updated as i go and answer as much as i can. i will take my time and give as good as an review/comparasons to help you choose your upgrade direction. i am anctous to fly but as usual im a dedicated b400 helper.
stock on the left (yes its bent) cncheli shaft on the right

Default more on the build

well got the tail, esc, motor and canopy in


tail is very nice.
shaft is steel alum removable geat 10t.grips have 0 play.sliger is bearinged on the no rotating portion.control arm is single point like stock. uses nylon bushings for slider portion and bearing for the arm. pitch change links are composit. and pinned in to the slider.the case is a single peace. stock shaft is not compatable. stock tail blades will need to be shimed (to slim for grips)


esc is quite big.
scorpion commander 45A esc v2
it comes in a nice pacaging. stickers, metal case. an IR programer and the IR remote.
looks like a very fine quality. and tons of features.

motor

the motor is a sonic 3500 kv motor gold and silver outrunner. mush stiffer to turn than stock. the motor is thinner and taller than stock. and will mount in stock motor mounts with no mods. came with a 13T pinion and compatable with stock main gear.
bullet conectors also are the same size as stock esc. not sure if stock esc is enought to run it effeciently.
.17mm shaft size.-------- Weight - 60 grams, Diameter - 25.8mm Length - 48mm Shaft length - 14.5mm Shaft Size: 3.17mm KV - 3500 current - 28A Max power - 320W

canopy
is a rex style fiber glass very stiff feels ruggid. has a opening under nose for vent prepainted glossy. will need to make own holes and gromits.

Head and tail look like good quality work.

I'm particularly interested in the tail unit. Do you have a part number?

Sokal,

Looks good. It will interesting to hear the flight review. It should be a great flyer. You said the tail gear is a 10T. If it is the tail rotor rpm will be high. The stock one is 12T. You may have to change the front drive belt gear to help lower ratio back down. If you have to then the G5 gears can be used if you make a thinner shim. Outrage has a 10t,11t, and 12t that can be used.

On the upgrade should I have got the flybar from cncheli to fit the aluminum head or will the stock flybar fit and or work ok? Because it was not avalible when I had ordered.

The stock flybar should work. The only thing is the flats on flybar may not line up with set screws. The set screw don`t have to be set into flat spots.

Sokal should be able to compare it and see how they line up for you.

I guess I'll have to get it apart to see what your talking about the flat spots must be to keep it from spinning . Is this correct? Maybe I should go ahead and order the right part. It's cheap enough.

Where the setscrews in flybar cage touch flybar on stock head there will be two flat spots on flybar. They will keep the flybar from turning if for some reason the setscrews ever slightly backed out. Many helis don`t have flybars with the flat spots.


If you have the cnc head you can compare / measure the flybar cage to the stock one to see if the setscrews line up

I think I understand what your saying. But just so that when I go to put this back together, I ordered the flybar and the aluminum landing gear so I don't run into problems. I hate it when that happens. I thank you for your input and advice and happy holidays.
