hi have hull and drives and rudder but was planning on gas decided to go electric so question will a 2 neu 1527/1y push this hull over 70 mph with good run times versus 2 2215/2y not to savy on electric but wanted high rpm and 2215/2y only good for 40k versus 1527/1y good for 60k not sure which has less energy loss for run times with two motors is torque on 1527/1y enough with two to still achieve over 70 mph and r the castle hv240 dependable enough to handle setupcan run 2 6s to = 12 per motor or 4 6s = 12s 2p

I would love to see some pics of this hull and hardware!

Not sure if this info will help, but I was planning a baja 5b (5th scale 2wd desert buggy) electric conversion, and did a bit of research on the 1527 vs the 2215. I concluded that the 2215 will have higher torque due to the larger rotor, but the 1527 is capable of higher motor rpms. I figured that I would just run more motor rpm and lower gearing to achieve the same top speed. So I guess you could apply this to using a pair of 1527 moors running a smaller prop faster than the 2215 setup.

All that is theoretical as I sold the baja to pursue a stretched 1/5 scale savage based monster. Still plan to use a 1527 on 10-12s though. Most people ding baja conversions who are knowledgeable about neu motors seemed to think the 1527 would be an ok substitute to the 2215, especially using lower gearing and more motor speed.

Hope that helped a little...

kinda what i was thinking since using twin drives versus single torque should be enough to get on top and go but im not good at all with elctrics so reason for post i saw a guy running 1527 twin drive on 60 inch cat hull it flew and had good run times but wasnt sure with 7 more inches of hull but apreciate the fast reply and tks but realy need some one with understanding of motors and speed controlers as i want deacent run times i know i wont compare to run times of gas but the speed gotta have it just dont want to spend money for 2215 when1527 will do but thanks again ps i just love to run remote control i have blade 400 3d and a gas 50 inch hydro and a black jack wich i hate i handles terrible also a team ascociated monster truck nitro so guess i should have stidied electrics well rambling on tks

i ran my Hpr07 with twin 1527 1.5y 825kv, on 10s i got 76mph with more than 4 mins run time, and 86mph with 12s and more than 3 mins (never try more time) with your 67" hull, FOR SURE i will go with 2215 or even 2230, i used to owned an HPR06 which 12" less than my present cat, i noticed that 12" is big diff, specially weight, so i guess your hull is weight way more than my, if i were you, i will go for twin neu 2230 10-12s4p(2p on each side) or if you asking for less speed, you can go for twin 2215 2y 750kv and still have to run 4p.
Note: 2215 and 1527 are similar power rated, but 2215 will run much cooler since its has bigger can and rotor, its also draw more amp than 1527.
here my video of my Hpr07 running on 10s, 76mph, enjoy.

yeah you boat rocks i seen before so now im confused should i go for a lenher setup 2x 3060/10 or neu 2230 wich has less draw or more efficency cause price would be almost same tks for reply also where do you get 12s packs lipo and charger as i was gonna use 6sx2

Neu 2230 is compare with Lehner 3080, between 2230 and 3060, i will choose 2230 anytime, same price more power and almost same weight , what esc you will use? if Schulze then you will be ok, if Hydra 240HV its should be fine too, since you are running twin, you will draw much less amp than single.
I use 4 6s Polyquest packs, i love them, never let me down, i got them from Unitedhobbies.com in HongKong, they take a while to get here but i got good price since im a Platinum member by buying alot of junk stuff from them =), you also can get Polyquest lipo from here in US but i dont know where, i hope someone will chim in for this info for you

was considering the hv240 cause alot cheaper than schulze hope they r good controler thanks for info on lipos by the way hi what kv would you sugest i like to hear the whine of motors i sat boat in water with drives and rudder it float light caint see motors and batts creating that much drag not sure though was told that 2215 2y would get over 70 mph good run time the boat float so high and move with little effort with two motors drag should not be bad but like i said im not good with electrics that why i ask on forum just looking for 70 mph with decent run time if the 2230 is same as lenher 3060/10 then that seems right choice but not sure how 1y is better than 10 wind for efficency could you elaborate please

Intresting Kevin. I was planning on converting a gas 53" cat I have to twin electric. Was planning on relaying some glass and refinishing the hull's gelcoat. Installing new twin scale drives from HPR, I was planning on Twin Neu 1527/1Y, 4p 5s 5000mah 30C Lipo's, (2p per motor 10s), and Hydra 240HV's. Was hoping for 80mph+ and at least enough time to complete a 6 lap offshore heat race for Namba.
You think I might acheive this? Or am I better off just dishing out the doe and getting a HPR135 Carbon Hull?
Sorry to jump on ur thread avery.

[kevinlew211]

what kind of weight that hull without engine?

can anyone tell me how to make 4 6s into 12s2p or is it possible

of course you can, its a same way i do and everyone else here.

so im gonna run the 2230/1y and 40/160wk 2x should i run the x 470 props l and r hand or the 670 both same which i have alrdy both left hand or would the x670 be to much for electric

you have to run L and R props, you can spin x470 R and L props with that setup no problem since you running twin, Octura dont make x670 right handed prop, for the best you should look at ABC props.
