Weigh in on motor comparision for 1:10 scale!

[ray schrauwen]

Is there more footage? I was distracted from watching a lot of races at the Nats and liked the shade better.

I ask for more because they look pretty quick. Not freaky fast like some LSH boats but, I like it.

When I was looking at Mike S. 1/8th scale build thread they are using some massive motors and esc's. I then look at 1/10th scale and the motors used and I scratch my head but, heck, I know so little about 1/10th scale and it's roots at this time. You guys put so much time, money and work into these boats that I question why such a minor motor?

I guess if the speed is too fast and you flip one it could destroy itself or more speed = more race carnage. I do like scale but, I'm so green with it. More reading....

If I build a 1/10 scale I'll ditch LSH as there is always P-Sport hydro.

ray I will try and get someone to video next race on the 25th..or 18th..i have had my boat to 51mph..with spec motor..still working on it..its really sensitive to wing angle

[ray schrauwen]

Cool. That's another variable, moving wings.

while we are talking 10th scales I love to run my vintage....2 vintage hydros with different props in this vid http://youtu.be/7BAfymCvji4 we probably have a ways to go to be up with the west coast guys but fun just the same

[ray schrauwen]

I might actually have a 1/10 scale round nose woody in the closet... I'll post pics. I think it's an Osbourne kit about 34" long.

Most boats are in the 40-45mph range.
The faster boats are in the 45-50 range.
It took me a solid season of testing and tweaking to get in the 45-50 mph Zone with my vintage boat.
Still have some adjustments to make it more consistent but that's because I push it to the limits.
This is with spec motors on 4s

I don't know how most guys measure speeds in their models, but some guys have told me that they get some strange readings from their data loggers sometimes during testing. How do most people measure the speeds? I have only used a gps device I put inside the boat and it seems pretty reasonable in measuring top speed. One guy told me that the data logger he has would show spikes of 70 mph and he doesn't know why. He thinks it might be the boat movement going into corners and giving a false reading somehow. Those things are beyond my intelligence right now, but they sound like you can get some pretty useful info from them if you know what you're looking for. I've always found that handling and getting in and out of the corners quickly in race water conditions is more important than top speed in testing, but it can be a guage as to how the boat reacts to changes you make. Besides, it's fun to compare with other people's findings and builds drama leading up to race day when you find out if all the hype equates to what you think will happen on race day.

I'll be data logging with eagle tree during testing and heat racing this season.
Won't be looking at top speed but will be looking at amp draw and rpms.

I used gps multiple times in my boat and consistently got similar readings ranging within 1-2mph most times for max speed. I find that gps is not always accurate if the course is a bit short as it changes so quickly and unless had a perfect signal a lot of times gps could be off a bit.

I think looking at max amps, watts, can size and KV will determine what motors will be comparable and then testing them extensively. Also, a short course may have them equal, but what about bigger courses and a variety of props? Ive gone up in props with my Himax, and my luck with the proboat has it relegated to spare to the spare...

Im curious of real course testing with eagle tree or equivalent.

ron have you tried the new proboat/dynamite motor??

[Ronbo]

I have not, tho I wanted to when I bought the older grey can from hobby shop. Ive heard good things, maybe they have the same QC as Himax now. Also heard proboat/dynamite stopped making the new blue motor?

[ron1950]

I have run the new dynamite motor in my vintage with just a 45mm prop and had great results..there is a vid of my boat outrunning another same hull vintage running the pb1500 but he is only running a 42mm prop...http://youtu.be/7BAfymCvji4
really like the new motor will try bigger props in the spring as I am back in Arkansas now and it 15 degrees yuk..btw the motor is cool to the touch with 45mm prop going for 48 and 50 next

really like the new motor

I wouldn't be able to get my miss Madison on plane with a small 42mm prop...and my boat is 6lbs RTR.

[monojeff]

I have new and old versions of PB 1500 motors and will post log info soon as I have it.
I will do back to back testing with no adjustments or changes.

[rayzerdesigns]

I will try and get some video this weekend testing..trying a couple new props
