Trasferrable BL Setup from easy* to e-starter to Formosa2

[Kam]

I am now planning to upgrade to brushless in the easystar first.

Am hoping that the ESC & motor that I get will be transferrable to an e-starter then to a formosa 2.

Do u think this combo can be used for these 3 planes:

Motor:
Warp4 BL4-15-4 Brushless Motor (1810Kv)

Pls advise how many "turns" can suit the 3 planes.

ESC:
Castle Creations Phoenix 25

25amp suficient or 35?

hi,
these 3 planes will prob need different kind of motor each.
For the easy star need motor in the range of 2200kv to 2800kv swing 5x5 or 6x4 prop. u can get the warp4 3Turn.

for e-starter n formosa 2 prob need a low kv outrunner prob in range of 800kv-1200kv depending on wat size prop u swing. e-starter prop a 8x4.3.

the formosa 2 is much bigger so need low kv but bigger motor, similar to axi 28xx range. swing 11or 12 inch props.

if u want to use same motor for all 3 planes , u prob will need a gear box n play around with the gear ratio. if u can find a gearbox for the warp4 3turn then will be good . can use for all 3 liao.

good thing is esc 25amps is good enough for all 3 planes. batteries can be the same also using 3S.

my 2cents. cheers

Thanks Mazon,

Yes i was hoping to go direct for the 3 planes, but looks like i need to use gear box for the e-starter and formosa 2.

Why don't u get the 2580 kv motor. The gear ratio used in the E starter and F2 would be different though. Just change pinion and gear.

The 3-Turn? In fact I'm not too sure as I'm following the recommendations from those easystar pilots in rcgroups. They recommended about 1800 kv for the easystar, as such they recommended the warp4-4turn or the MEGA 16/15/5 (rated about 1800kv also).

If i put in the 3-turn (2580kv), what will happen? If no probelms then i rather get the 3-turn cos its cheaper!!!

I think for e-starter and formosa 2 i will juts gear it, shouldnt be a problem.... unless the motor cant fit in the gearbox!

the other model wattage rating is lower and to fly thr formosa 2 with some nice vertical ud want some more watts

OOps im wrong sorry did not take a look at the other motors.. usually higher KV higher wattage sorry!

[Kam]

Thats wat i'm finding out too. Higher kv=higher wattage=lessser no. of turns. I find these all very confusing... then got thrust, rpm, amp pull, prop size, diameter, pitch... and all these have to balance nicely with the motor, prop, esc & battery.

Heli so much simpler, nearly everyone on the same setup... right down to servos & rx even!!!

Hi there,

Guess what, I used one single BL motor with one single esc for 5 different planes so far. Just keep on migrating them over to the next plane.

My planes were , estarter, gws zero fighter, phoenix tucano ep, china brand Su-31, & ultrafly ultimate bipe. All of them have been using the same motor.

The trick is stick to the park flyer size (380 to 500) airplanes and get an outrunner BL that runs 15 to 18 amps max. (about 150 to 200W). Example, hacker A20-20L outrunner, himax 2812-1080 outrunner.

If u get such a motor u will not run out of planes to migrate your motor to. You can save $$$, concentrate on flying one a/c at a time. Because the parkflyer size of RC planes is experiencing a phenomal growth. Just keep on changing the plane body will do.

did you ask the same question in RCG? funny that someone else asked the same and also about the warp 4!
anyway, the formosa 2 is twice the size of the estarter, so you will either have a over powered estarter or an underpowered formosa 2

Agreed!

Shoan, I'm not sure if an AXI 2208/20 can do the same for what u mentioned. Can it?

[shoan99]

Agreed!

Well, i think just any quality BL outruner with a maximum continuous current draw of about 15amps will be able to fly many types park flyer sized a/c. Just have play with different props.

THe axi 2208/20 gold line is rated as 12amps continuous, 15amps burst for 60 seconds. While my a20-20L is rated 15A continuous, 18A burst. But i think shouldn't be a problem. My friend is actually flying a aerobatics 600+grams balsa ep plane with himax outrunner 2812-1080 (almost same ratingas axi 2208/20). No problems so far.

according to himax website, 2812/1080 is equivalent to the AXI 2212/26. And with the 2812, u get a 4mm shaft!(less easy to bend). Himax 2812 is cheaper too. And if u buy it new, it comes standard with stick mount, backmount plate, prop adapter, prop saver and connectors!

On the other hand ppl who only fly planes and dunno about heli (like me) will also think that heli is extremely complicated with all the tiny mechanical moving parts and all the fine tuning to do.

I think don't have to worry too much about all these very detailed things. Otherwise it's not fun anymore.

Just stick to certain rules like:

1. Use an esc that can accomodate the motor's current.
2. Don't use a prop that will cause the motor to burn.
3. Prop for 0 to 100watts per pound of plane for aerobatics or 60 to 80 watts for leisurely flights.

The rest of the boring details you will slowly discover yourself when you are having fun flying. My approach is like that lah. But of cos there are ppl who find joy at looking at every single detail and calculation until they wan to get 101% accuracy. As long have fun can already.

oh yes. the 4mm shaft really v hard to bend even after my friend crashed his on tarmac. But i dont know about efficiency. The 2812 sounds noisier.
