Hows every1? havnt been flying my 2, qj8s much but today I did and I just cant understand the difference in power of the 2 helis unless my packs have gone bad from sitting .My 6s qj8 has so much more punch than my 4s its crazy . Thhe 6s is 2 TP3s,2100s in series and the 4s is a PolyRC 2500.The moter on the 6s heli is the A30-10xl and the 4s heli is the A30-10 Hackers. Remembering months ago when I got the Polyrc battery it never did have much punch , does any1 know about these ? I weighed the packs and they both weigh in around 270 grams. Any advice ? Im thinking I might sell my 4s heli. Thanks Pals

Welcome back, Wheres everyone been? I recently bought a Zpower Z15, It weighs 130gms has a 35mm dia. and a 1250kv rating, and get this, its rated to handle 6s. Well, I skeptically rigged the whole thing up in my EX last night and charged my 2 Flightpower 2500 3s wired them in series for 6s. The power is there, I need longer blades, the motor only gets warm, and the packs are just a bit warm, and not blazing hot like my 4s setups. 6s is definately the way to go. I dont know if its the motor or the timing on the esc (iLL play with that tonight but im sure it has to do with the pinion size Im running) but the packs are warmer than I remember when I flew this setup with a Hacker A30 10XL last year. The motor has promise probably work well in a SP on 5s. sorry for the bad shot.

my advice, go with 5s or 6s, they are more powerful and more efficient, some packs are available as a 6s 2100mah pack (of course youll need a charger that can do 6+s) This motor although not as powerful as the Z20 1500 is exactly what Ive been waiting for, a lightweight compact motor that handles 6s.

Oh and one last thing, the smallest pinion I have is a 14t, so I put that on there and dialed down the Throttle curve to 90%, I just made a big order on pinions including 10,11,12,13,15,and 16t, so Ill be experimenting alot with this Z15 and the crazy Z20 in the following days, as long as the rain stays out of my way.

I , too , am very interested in your results with this Z15 Zpower motor ...
I have a Z30 on my EP16 and a Z20 on my EP8 EX and these Zpower motors are some of the best motors on the market , IMO , they are just loaded with gobs of torque..
Keep us posted twinring!!

Ive never had a 5s lipo but If I did I wouldve tried it, My A30 10L sits in a box these days because im addicted to the power of more cells.

I think it would work just fine , BUT, you will have to use a smaller pinion, 13 or 14 tooth should get you right at 2500RPMs!!

Jimbo,
yes ive flown it twice, the power is impressive for such a small motor, This EX really needs to go on a diet, and the right pinion gear needs to be put on there as well, so Ill have to dial all that in. I really do think the Z20 is where its at, but 10t pinion and special frame mods has me confused. So the Z15 is so much easier to work around. I drafted the ESC mount in CAD, and then emailed the files to some guy over here who fabricated them, but hes too busy doing bigger jobs to worry about my little parts, Im thinking of editing the drawings and having someone else make them, If you are interested I could have a small run made for just a few of us because I need one more set for my EX, the one in the pic is for an SP.

hey Tailboom,

Its a 2820/10 on 4s, recently all my 4s setups run super hot and I think two of my 4s packs are on thier way out, so Im thinking of buying 5s or 6s replacements, This combo was great in the lightweight SP, but im leaning toward higher cell counts for more efficiency, and a cooler running system, of course the power is great too

I need more juice baby.....

Hey Twinring, I am running a EP8V2 EX, with a 5s1p 3700mah FP lipo. My motor is the stock 890kv job, with a 19tooth pinion. I am lookin for more power (flying 425mm carbon mah blades) What motor do you reccommend for this setup for max POWER... (running a CC 80amp ESC in Gov mode)

Cheers,

Woody67

I think Jimbo is right, you need a higher kv rated motor, you could try the Z15 on 5s But I havent seen any overseas yet.
