7HV motor options using gear already owned

[blackcataps]

A supplier I've used before is showing the 7HV in stock but the only option is kit only so no blades and motor. I have a compass 6HV with the stock motor and I'm very happy with it so I would normally go down the stock motor route but I was recently going to build a trex 700 nitro to electric conversion but ended up selling it as a nitro and have a new kontronik 700-52 motor and jive 80HV ESC and was wondering if they were a suitable set up for a 7HV? I can't think why not but the reason I use this forum is I'm no expert when it comes to electronics etc. So to get to the point if I buy the 7HV as kit only will the 700-52 and jive 80HV be a good set up? Will be using 12s (2 x 6s 4500 batts in series).
HELP please?

Anyone???

I wish i could answer you question but dont know enough about leccies. I would have thought if you had selected it based on a 90 size nitro to electric conversion it would be fine in any other 90 electric.

[FONT=Times New Roman][SIZE=3]Compass 7HV stock motor is C5032-570 so is 570KV motor , I understand some also using Scorpion 4035-560 as well which is 560KV, I am not familiar with 700-52 so you need to find out what KV is this motor, but Jive should be OK.[/SIZE][/FONT]

That combo will do. Maybe:
add the heatsink
or go for the 120 hv

both these options are for extra headroom. The 80 will be ok I'm sure

The 700-52 motor is 520KV. The first set of numbers are the range number so 700 and the second set of numbers is the KV minus the 0 so 52= 520. asid what do you mean by extra headroom? I've done some calculations using heli calc and mr mel's and it seems with the gov function on the ESC set to somewhere around 75% and a 12 tooth pinion it will give me a head speed of around 1700 which I understand is about right for these big electrics. Does anyone know what the ideal head speed is for the 7 HV. Cheers

Hi Andy,

the preversion manual states a headspeed between 1600 and 2100 rpm's max. When we're talking 2100 rpm's this is the headspeed for full hardcore 3D smackdown ;) Beginners : headspeed between 1600 and 1800 rpm, advanced pilots headspeed between 1800 and 2050 rpm and this with the 12tooth pinion, and for the top 3D pilots : headspeed between 1900 and 2100 rpm's on the 13 tooth pinion.

Grtz,
Dirk

Thank you for that Grtz. Makes a lot of sense. My limited experience with the large electrics starts and ends with my logo600se and that seems to need a slower head speed than most. Looking forward to giving it a try.
