T.P or Leopard motor???

[Mad Racer]

Hi.

Need some advice. I'm building up my new Apparition hull to race in 6s class next yr. This will be my 2nd Apparition as the first one hit the rocks and destroyed the hull. So This build will be better in every way. The motors that I'm looking at are from T.P and Leopard. The T.P are more expensive by $30 each. I'm running twin screws. I do want this to hammer and last. Even though the spare hull seems thinner than my first for some reason.

What would your choice be??

Cheers

An Apperition would not be my choice, it is very narrow for a race boat, and very small for 6s.

From the research I've done, I believe TP to be the better motor. There is a tear down thread somewhere here that shows the rotor to be of similar build quality as Neu. Even braid over the motor wires shows the attention to detail. I do not have any first hand experience comparing the two though.

I just purchased one for my mono build.

Me and a few of my friends use to run Leopard motors but now we use TP Power. We find that the quality is better and they can take the high rpm's better than the leopard.

Not what he was asking. Looks like he was happy with the previous one he was racing. Everyone lines something different.

Op, I was very close to pulling the trigger on a tp motor. The research I had done turned up the fact that people prefer the tp over the leopard because they are a little better quality. I've never seen a tp so I can't confirm that. What I can tell you is the leopard 4082 I have right now still looks to be nicely built. My castle motors don't look that much better in build quality.

I've been using TP Power on 6S for quite some time now.
I have 3 x 4060s in various winds: 1800Kv, 2100Kv etc. both ribbed and smooth cans.
These motors have taken quite a hiding at 200A plus.
TP Power state they are good for 50,000 RPM and I've had them on the edge.
Tried Castle and wasn't impressed with the upper bearing failure I experienced.
1/2 the price of Castle too.

Water jackets are essential.

I'm currently dabbling with a 6 pole 8mm shaft 920 D wind on 12S.
Due to driver error I've even dredged the bottom of the lake upside down and filled the can with mud.
A wash and lubrication and away it went again.
I have yet to experience a failure with a TP Power motor.

I have to giggle at comments which link quality and performance with "looks". Can "looks" determine magnet quality? Can "looks" determine wire quality? Can "looks" determine bearing quality? Chinese motor makers will spend more on "looks" because that is cheaper that spending money on component quality. Which would be a better motor, a Neu with a rough can finish or a Tacon with a gold plated can?

IME the TP performs a bit better than a comparable Leopard. Neither is a Neu but you get what you pay for. For most sport boaters either will work. Is there a noticeable difference? It will be small. A better choice for performance without the Neu price? The HET motor line has proven high performance and is built like a Neu. Not a Neu but close. The biggest problem is a more limited selection in Kv.

Thanks for all the input.

Much appreciated and I see everyones point. My Apparition is my first F.E.B and I do indeed love it. Unfortunately I had a radio glitch or malfunction of something a couple weeks ago and turned right at full noise into the rocks which has really smashed the hull to bits. I just recieved a replacement hull from H/K but it seems a little thinner in glass. There is a guy running a Apparation with twin T.P 4200kv motors and it is just nuts but seems to always be running into stupid little reliability issues . So this new hull will be built up with new motors . Was looking at 3500kv as my older Apparition had 2990KV 4 pole TFL motors which i put in replace of the RTR mors with 3 blade props and went very well, considering it didn't even have counter a rotating prop set up. The new Apparition will though.

I was advised to go to 3300KV motors but if i'm spending $150 on new motors I want it to be a good step up hence the 3500kv motors. I know i'm right on the borderline of performance & reliability and Steve has helped me out here so 2 new Leopard motors have been purchased from OSE & is being shipped to OZ.

Can't wait to start the build up.

Thanks guys.

I would fix the radio problems first. Why build another boat and destroy it again?

[Fluid]

If the OP is using 6S per motor then 3300 Kv motors are a big mistake. They will work fine on 3S. And as above, have a reliable radio. If the radio is not reliable the you don't have radio control...

Faulty on board electrics

I would fix the radio problems first. Why build another boat and destroy it again?

As I said I had a malfunction in the Ap not my TX as I have used the TX quite a few times after the accident. I'm not sure what went wrong but it was either a servo problem or RX. I suspect the RX is the problem since the day before I was trying to fit up a UBEC with no success and I feel I damaged it in the process. I have replaced or the electrics including esc's in the new build. All the original electrics are sitting in a mess with the destroyed Apparition Will check it later after the new build is finished as I'm still upset over it and want to move on.

Yes 3s per side. 6s total..

Cheers

Not what he was asking.

I know, but I would feel bad if I didnt tell him before he sunk a load of money into it, just in case he thought it could be competitive on 6s at a high level.

Interesting. I am not familiar with Aussie rules but that is considered 6S in NAMBA, depending on pack capacity. I assume you know local rules.

Fluid, why would you giggle when a person makes a statement that the motor looked good. People are capable of making the distinction of quality based on appearence. What makes a motor look good, fit and finish of components and quality of machined surfaces are a couple reasons a person may decide a motor looks good to them. If something looks poorly made because of the same above reasons it will likely have performance issues. Simple and very important issues of quality based on looks, whats to laugh at?

You are right I will be racing in 6S. I don't think that pack capacity is anything to go buy as long as you can do your mill lap and 5 lap racing distance.

Why is the App not a good boat for club racing? Yes it's a narrow boat but if I can get the batteries down in the hull with the motors and get the balance right this would really help. I'm trying to get 2 race boats together for racing next yr and my other boat a deep V with a stepped hull which is not allowed to race. So I just bought a new ATR deep V as well. You have to start from some where. It's a big out lay at around x mass with Batteries, Chargers, Boats and running gear. Not a easy time for most

I'm only racing at a small club next yr but have some really knowledgeable guys and a few Australian champs that are helping me out. Props is the biggest issue and I have a top Prop Doctor to help me. Great little club.
