Weigh in on motor comparision for 1:10 scale!

[Fluid]

...Most gps aren't accurate anyway.

I cannot speak for "most" but almost a decade of comparing GPS speeds with SAW timing lights has shown me that the three GPSs I used were very close to the lights.

Ray - Sorry to hear you are experiencing some sort of drama in your club/district.

FYI - Going forward I will continue to make defensive posts when unsubstantiated statements are made concerning what we do in IMPBA D4.

Good luck with your motor dilemmas and Happy Holidays. Doug

Now, now, I said close... not the same that's for sure. Remember is not really a Turnigy, it's a Suppo. That's all I'm pointing out. The Scorpion is a step up but, not a huge one. I've have both Scopion and Suppo but different winds. kv...
A pair of the lesser 3650 hobbymate $22 motors can push a rivercat to 64mph with little effort. The Suppo is even better quality. Then can be abused a fair bit.

I'd say the Suppo is about equal in quality to any PB or AQ motor in my less than empirical testing, too bad I can't get the 2200kv ones anymore.

and you know the quality is because you have comparison tested several samples of each? Hmmmmmm. So you don't get what you pay for? And Scorpion is screwing us by a factor of six? Sorry, I don't buy it, based on Turnigy's quality history.

Kind of curious on how you came to this conclusion.

Fair enough. I don't have real world testing. I know I read at least one claim of more speed in a Popeye boat. Einstein I believe.

I have seen the TP construction. I can make an educated prediction. It's a better motor. Much like a scorpion is a better motor than a the old PB 1500. I didn't have to test that to predict what would happen either. Ken was running those years ago. The construction is great.

The TP has 20% more mass than the AQ. They didn't fill the can with fudge. More magnet, heavier wire, something.

We didn't find the sweet spot on a 2030 in a just a handful of runs. If you ran the exact same prop on both motors they should have been nearly exact. You could run the same props on the TP as the 2030's turn but eventually......somebody won't.

[Doby]

Yup...

Ray, are you sure your 10 scale was running 54 mph with the Scorpion motor? 80% of the LSHs that are out there probably don't run 54 mph. If so, you have basically nuked the Scorpion motor from being approved. This motor will never be approved if it's 6-7 mph faster than the other motors. I'll be doing more testing with my Scorpion. Most gps aren't accurate anyway.

yes greg..its 5mph faster than any of my namba legal motor for scale..

no dilemma doug..mitch,s club is testing them..not for namba approval but for club..i plan on attending some of his races so I bought a motor to test..

Funny how hard it is to get everyone all on the same page.
Lets just make a choice and get to some racing!!

My experience with these motors:
I have been running the PB motors in my boats now for over 1 yr and they have never given me issues or problem.
They will spin a 450/3 blade that has been cut down some no problem.
The old SV27 blue I burned up in 1 season with a 447/2 blade slightly cupped on my vintage boat which was very fast but obviously pushed this motor to much.
I know that the PB motor and the Himax motor real world testing are basically identical in speed and performance.

At the moment I have I think 5 PB motors and if they were to change the rules and I would have to buy new motors then I most likely would not be able to rave anymore.

Here is how I see things for out boats in percentages:
25% Motor (Speed, Performance)
25% Prop (Speed, Performance)
25% Driver (Reactions, Driving Style)
25% Hull Design (Each Boat is different and has it's own issues and flaws that have to be taken account for not all boats run great in like conditions.

We will never ever be able to compare apples to apples but we can all get similar motors to keep things closer competitively.
We have had people come run with our clubs with other motors and never has it been an issue with competition.
We all blow over at times, we all get bad starts. Drive more consistent and be on the clock = fast boats!
I have seen the slowest boat in the club become one of the fastest in the right drivers hands!

there is no dilemma in our club in Scottsdale..it sucks you aren't coming to race with us in feb..had fun last year meeting you..and racing with you..and yes our club follows namba rules..yes rules state cd can make a judgment call,,which he did..we put it to a vote at our first race in November..it was a unamimous stay with motors that are in namba rule book..happy holidays to you also..on that not merry Christmas to all

Wow, a lot has happened since I lost track of the thread temporarily. Thanks for everyone weighing in. I too believe the best we can do is to try and find motors that are close to include in this class. Outrunners and their qualities vs inrunners is still a bit of a new thing in boats. More testing is ahead, but right now it it looks like my concerns were warranted and I've learned a lot with your help. It appears that maybe an outrunner with a much higher wattage rating and similar kv rating and size is too much of a difference in performance. I would need to test this, but I suspect that the Scorpion HK3226 1400 kv version would be a better fit when compared to the available NAMBA legal motors today. I've also got my eye on the very affordable Leopard 3650 (1650 kv version) as something to consider in the future. The industry is just so unpredictable with the RTR offerings. I don't see the harm in doing our homework and seeing if we can stay a little ahead of the game if we can. 1:10 scale is steadily growing with clubs and individuals running them all over the world. Sure, you'll get the lion's share out west and in the Detroit area and where the real boats have been popular, but I get emails from all over. It surprised me. These kind of discussions really help, even if we ruffle a few feathers here and there. I'm always interested in different opinion and this has been huge for info gathering. Thanks guys. I'm hoping that in the future it will be easier to identify motor options using some of the manufacturer's specs as a place to start. Knowing how to look at the numbers at the same time you look at inrunners vs outrunners of comparable size is challenging, but I think it's well worth it. I'd hate to leave them out as options.

Nothing... damn internet won't let me delete this, I have nothing to add to this conversation, sorry! Don't race these boats so my opinion doesn't count for squat!

[rayzerdesigns]

Mitch you should try and make winter warmups in Feb

Ray

we put it to a vote at our first race in November..it was a unamimous stay with motors that are in namba rule book

Lets see how this shook out. WW has 4 less participants. Each would be participant saved $1,500 in travel costs. We both lost the oppurtunity to run 4 TP guy's against 12-15 AQ 2030 guy's. Could have really put this entire debate to rest in one fun filled weekend. This race was never about records or notority from winning. Now its about a rule book?

As President of our Badger Model Boaters Club and IMPBA D4 FE Director I can assure you or anyone else that our club will keep the door open for anyone to run any boat. We'll find a class to run it in. It's a Hobby!

Cheers - Doug
