HK & TP Power Motor Info (5660 5692)

[FighterCat57]

Met with TP Power in Germany this weekend and got the permission to share what happened that the 56 series motors ended up at HK. This info is directly from them, but please take it at face value.

TP uses an electronics manufacturing company to make the parts for the motors, castings and coil assemblies to their specifications.

Hobby King went directly to that manufacturer and stocked up on the 56 series motors. Basically putting TP in a bad position, as TP's cost for smaller batches is more than HK was selling them for retail.

Note - HK did negotiate a lower manufacturing cost by reducing the cost of the individual components. One of the ways they achieved this was by using a shorter magnet & coil length. Essentially putting less material into the same size case. Using more common bearings as well.

I don't have an HK motor here for comparison, but did see one in Germany to compare, there was about 3/4" of empty case inside of the HK version. The comparison of the HK 5692 to a Leopard 5692 was a close one (tested by a German RC company) only about 10% difference.

Ive got one which should be turning up.... eventually. It was the 1700KV 5682 one.

Ive had a good experience with the Turnigy 4074 2000kv on 5S.

I think we would need to actually take apart both motors and do a side by side comparision before saying that one is definatly "better" than the other.
To be honest, do you think that TP Power is going to say , "Yep they just went to the manufacturer and bought 100000 so they got them at 20$ each"? no.

I got mine to put into a MMP Rapid

Andrew, that is exactly how HK works.
We have a couple friends in HK and they do business with them and that is their
way of doing things. (Buy in bulk at a reduced rate and with the components
of a BIT lesser quality.)
While alot of their goods are good quality, alot of their goods are of "ok" quality. (they work but for how long?????????)

I don't know but half price is suspicious

[Alexgar]

ben are you saying pretty close??

To chime in, I bought HK's 5692 1320KV motor & it at least looks & feels great compaired side by side with my Leopard 5692 1340KV. The can is a bit longer than my Leopard's, but at 1/2 the price of a Leopard it's a great deal for testing & playing around. I also bought all 3 of their 3600 series motors (KD36-74-06XL; KD36-60-07L; KDKD36-50-11S) & have tortured them enough while testing props to melt the silver solder ESC/motor wires apart 4 times. Motors, of course, got hot but have yet to fail. For testing & pratice HK can't be beat.

When it comes to SAWs & offshore I only use the Leopards. I'm just too poor for Castle Nu or european motors. JIM

It works for WalMart

I got your email Benjamin, have been at the track so sorry I didn't get back to you yet. I have both 780kv motors here, TP and HK, I'll have a look see tomorrow and let you know what I find.

Regards, Kyle.

Ps those 24s controller are ridiculous, seriously no words to describe them. Nope, none.

6BOOST.
Wil you open them?

Personally I think there should be independent people with no ties to either company doing the testing then the results would have more validity

A few more observations compairing my Leopard 5692 1340KV & HK 5692 1320KV motors. OVERALL LENGTH: Leopard 92mm; HK 93.5mm - MOTOR DIAMETER: Leopard & HK 56mm - SHAFT DIAMETER: Leopard 6mm; HK 8mm - WEIGHT: Leopard 963 grams; HK 870 grams - FRONT END CAP: Leopard 4 bolt; HK 6 bolt. MOTOR WIRES: both about the same in size & flexabitily - BEARINGS: Leopard uses top quality Japanese; HK unknown, look cheaper, but if they fail - bearings are not that expensive.

Time will tell if HK - at 1/2 the cost - can match the performance & endurance of Leopard motors. JIM

Sounds great to me!

They are the Australian edition. =)

The inner rotor on the FighterCat Edition TP 5692 is 60mm, not including the retaining portion, just the magnets.

I should pull a 5692 apart to see the rotor length as well. Curious what the HK length is. If it has the 40, 50 or 60mm magnet stack.

I fully agree Jim
