Tamiya TT02 Speed Challenge Run 6: Do Batteries Make a Difference?

[@NordicRC]

Hi Mark! That’s a fast TT (and cute squirrel). Yeah, with that gearing I would have expected a bit more too. Hmm. Must be the batteries not providing enough amps and voltage for the motor? If you can get hold of a 7 cell high mah it would probably do the trick … or maybe just burn the motor 🙃 Anyway. 55 kph is very very respectable !

[@MarkBryanRC]

Hello Mikael! Yeah, not too shabby for a TT02, stock(ish) chassis! Everyone was talking about the squirrel we nearly ran over last year, so Rob thought he'd get one that we couldn't hurt!!! 😅 Yeah I think the batteries are holding me back a little - I have a 7 cell coming! We will se how good this motor is! Cheers my mate! 🤗💙👍

[@AdventureTimeRC]

Good stuff Mark batteries and connections make a huge difference in my experience I have seen huge improvements to rc cars and planes just by batteries and connections large enough to deliver the power 34 is a great brushed speed

[@MarkBryanRC]

Hey Brent thanks for sharing your thoughts on this! 😊 I think we agree on this subject my friend, I need to look at those crappy Tamiya connections I'm using 😅 All the best, dude!

[@AdventureTimeRC]

@MarkBryanRC have a great weekend Mark all the best

[@BangForYourBuckRc]

It’s very nice of your fans to send you stuff to help with your run. That’s so great! Your squirrel mascot should stay even after the speed comps are over! 😝 34 mph with the old pack is pretty solid. I bet after a few charge cycles the new pack will be as good! Great entertainment fellas as always! Stay cool 😎 - the both of ya!👍🏻😝

[@MarkBryanRC]

It sure is nice, Robby! I have made some awesome friends in this hobby and they are so helpful and generous 😊. I think that squirrel might just become a permanent fixture!!! As for the battery 🔋 I agree with you, it needs a few cycles before it'll be at its best 👌 Thanks for watching, dude and all the best from Mark and Rob 😁

[@RCBirds]

Congrats, that's an awesome result. I like your mascot, too😂

[@MarkBryanRC]

Awesome! Thank you, Dirk! I think we might be seeing more of that little creature! 😅👍

[@AddamsPlayground]

You guys are killing me with the squirrels! LOL!! I am looking all over the place now for them! Glad you got a but more speed out of it and 34 is good for the gearing you got in there! Keep feeding it gears! LOL! I just came up from swapping the brushed motor back in mine and I managed to cram in a slightly larger pinon in mine again (bigger than the 42 that was in there!). I am surprised I was able to fit it in there so one last run with Ricky and the new 15t Reedy Radon brushed motor will be coming soon!

[@MarkBryanRC]

Haha 😄 🤣 sorry about all the squirrels, mate, it's Rob's fault, honestly 🤣 Yeah another improvement but you know I want more ... I still got a few tricks up my sleeve though! Good luck with that 15t motor, boy, you are pulling some gearing ⚙ there! All the best 👍 👌

[@madsrcbuggy]

Ah, ha ha, the squirrel! Great run again, Mark! Some sort of steering issue but once you got it sorted it ran straight and true, very nice! Yeah, I agree, the battery is really essential for a good run, like you just proved here also. Of course with bigger capacity comes greater weight, but it seems the power helps with that... "Tooth", ha ha, I have to admit, I got tooth and turn mixed up a few times, too... I have a 27 and a 29 tooth pinion also, ready for next runs... Have a great weekend there, my friend!

[@MarkBryanRC]

Hello Mads! Yeah we just had to use the squirrel in my videos as well as Rob's! The steering issue was caused by the trim setting getting knocked in the RC bag! Should have checked it before doing the run! Yeah I think I got the chassis sorted now and it goes in a straight line most of the time now! As for weight, that will not affect top speed, only acceleration! So put in the fattest battery you can! Tooth and turns, what am I like? I blame my age! 60 next month! 😬🤫😅

[@rcprescription]

Nice run guys!!…. And you are always good for a chuckle or two!!..😂😂

[@MarkBryanRC]

Thanks dude, as you know we do like to keep it light-hearted! Glad you enjoyed it! 😎🙏👍

[@dominicchesterman2107]

Thanks for your advice on the Absima Eco Thrust motor. Been kinda modding my FTX Banzai using your videos and I've got it to a good speed now. Hobbywing 1060 esc, 2s Lipo, the motor and some rally wheels and it goes well!

[@MarkBryanRC]

Hi Dominic, yes the Absima motor is awesome, especially considering it's low price! Glad you have found these videos of some use, it makes them worth doing! All the best from Mark... 😎👍

[@theoagrc]

Nice T-Shirt Mark! You getting sponsored now mate??? 😁 Are you slowing down on purpose?? Joking aside bud 34mph is getting there pal! Keep going dude 🙌🏻 Interesting comparison with the batteries there dude! I am noting down all these tips ready for the next OAG run 😁 “Oh no we got a dead squirrel” brilliant Rob 😂

[@MarkBryanRC]

Thanks dude, oh yeah I wish I was sponsored! It was a free shirt though, they messed up the order for the LRP motor and sent the shirt as compensation! Slowing down... come on Bro - I'm up to 34!!!! And a bit faster since this run, Shhhhh!!!! I'm eagerly awaiting your next run, you better get that thinking cap on and get it turned up to max! ...Don't listen to Rob, he's a liar and hamming it up for the camera, no squirrels were harmed, I promise! 🤣😬👍

[@theoagrc]

@@MarkBryanRCI have plans dude but the rain has stopped play a little this weekend! If I get a dry run I am turning up the screws this weekend!!

@@theoagrc Good luck dude, you are gonna need it!!! 😅😉👍

[@mad-beerc3818]

Haha getting there Mark and camera man(Rob😉) and the batteries definitely vary in power! I use VP batteries usually 3700mAh seem spot on for capacity and power and charge time! They seem to be pretty lively compared with some l have had before too! Great stuff chaps.

[@MarkBryanRC]

Hi 👋 James and thanks for the great comments as always 😀 👍 I think the quality of the cells is a big factor here, those VP batteries 🔋 must be well made! It was awesome chatting to you and the misses yesterday, ❤ we must do it again soon! Take care mate! 👍

[@mad-beerc3818]

@@MarkBryanRC Haha plesure Mark it was excellent to chat and definitely again anytime mate! Regarding VP batteries yeah l just find them to be good! I have nothing bad to say about them! Iol next one l buy will probably end up being a dud! What NiMH packs do you use mostly Mark?? Any favourites or just use anything?

[@PeteWylieRC]

Hiya mate. Hey that's a decent result. I'm thinking that I haven't got any more ideas when it comes to brushed and NiMH. Just gear it up as much as you can until the motor can't cope. Loving the squirrel making an appearance. I think it should be your channel mascot. Anyway no new speed runs from me this week. Being a bank holiday in Bournemouth I expect all the car parks will be full and the camp site road will be busy. Still plenty of time and really we don't stand a chance in the contest so it's just for the jolly banter. I've got a pint on the go to see in the bank holiday so cheers to you and all the speed run boys 😁🍺🍺🍺🍺🍺

[@MarkBryanRC]

Hi there my mate Pete! Yeah, 3mph more by going up 5 teeth is OK but I really was hoping for 5mph more! I was worried when there was no speed increase on the 1st battery. Anyway I still have a few dice to roll. Hope you get chance to get another few runs un soon, but by the sound of it you'll be better off waiting a few days. Enjoy the long weekend and all that beer! Best 👌 to you matey! 😁👊👍

[@poorboysrc]

Ahhhhhahahaha!!! The squirrel strikes again! So funny!!! Too bad the new battery didn't pan out as hoped. Hopefully a higher mah pack will get you into the 40's! 💨💨💨

[@MarkBryanRC]

Hahaha! Yes, Fil, I think this squirrel will be a permanent fixture, thanks to you! But yeah, it was worth a go with the new battery, the old one came good though! I'm going for a 7 cell pack next, it's gotta work for me, fingers crossed! Cheers brother! 🙏😎👍

[@ShenRC]

Nice run looks like the good old awanfi did the trick! Hard to find a quality nimh packs these days maybe a traxxas one will be good?

[@MarkBryanRC]

Thanks Steve, yeah that old Awanfi still delivers! I got a bigger pack coming so fingers crossed! 🤞👍

[@ShenRC]

I learned over the years Mark it's not the more milliamp hours that makes the pack better it's all about the quality of the cells they use in it. and back when there was no lipo packs they used to make really good nimh cell packs now nobody does and they are mostly made from cheap cells, The traxxas nimh packs If I recall where good but they are only 3000mah.@@MarkBryanRC

[@MarkBryanRC]

I think you are right, Steve. Most our equipment is cheaply made in China these days, more's the pity. I have got a new 7 cell so I'm pinning my hopes on that! Cheers, pal!

[@NANNIRC]

And now the challenge is between you and Addam! Nice shirt. Ciao Nanni

[@MarkBryanRC]

Thanks Nani, yeah, there are a few of us in the brushed class and very close in terms of speed! I will keep trying my friend! Ciao!

[@DetoursRC]

They definitely did for me. Higher c rating and higher mah helps. Check out my run Im about to film another this weekend. I use smc 6500 150c 3s

Brilliant stuff Mark 👏 love watching u guy's 34 nice run. R u able to adjust the timing on your brushed motor ? If so loses the end bell and turn that motor up at least 10 degrees . U will get 10 more mph at least. It's raining today on the east coast of the states so no runs for me today. Good luck and have fun 👍 👌

[@MarkBryanRC]

Hi Chris and thanks very much for the info! Yes I can adjust the timing and will start playing with that soon. I still have a few more dice to roll and I'm really enjoying the journey! Sorry you got rain, we got rain 🌧 here too. Fingers crossed for the next runs, good luck too, buddy 👍

[@fpvDRE]

spot on marky we dont realise how batteries stop performing after a while wether there looked after or not nice speed that 👍 EP do some fantastic nimh cells too brother i had a 9 cell pack on my vxl stampede and that thing flew 😁😁

[@MarkBryanRC]

Absolutely, Davey! I think the quality of the cells is the main factor, for a long time the best performing pack I had was a Sanyo NiCd 1700, it delivered a real punch but sadly it's dead now!!! Ohh, a 9 cell? That would liven any RC car up!!!! 😜👍

[@forgetfulLlama31]

nice Mark!.. hi Rob you legend ❤

[@MarkBryanRC]

Hi there Jason! Yeah, that Rob Brennan bloke is a true legend! Cheers 😎 🍻

[@PrankedzeerbestePulsive]

Me and my dad noticed aswell that a Lipo battery pack makes our RC alot faster than a NihM, used a Lipo on our h-king desert fox and got incredible speed, but now our engine runs very hot and the gears do not like it 😅Also destroyed a suspension arm since I might have driven it into a curb...

[@MarkBryanRC]

Thanks for sharing! Yeah I use a Lipo sometimes and it does perk up my RC cars! Too bad you broke your car, those curbs are RC killers! Take care! 😎👍

[@HaydadRC]

Always seems like a cracking time when you fellas do a video! 34 is pretty impressive!👍😊

[@MarkBryanRC]

You know us two, Jeremy, never take things too seriously! Thanks fella, I'm pretty pleased with 34 but still have a need for more speed!!! 😉

[@MauzyrockRC]

NIce run this time! You can do it! Don't hit the squirrel!

[@MarkBryanRC]

Many thanks, A! More speed is hidden in this chassis! I promise that no squirrels were harmed in the making of this video! 😅👍

[@barrycheesemore2928]

34mph is pretty good! I'm pretty sure the mAh of the battery will make some difference, but so will the discharge rate, if your discharge rate is higher then you'll get more 'oomph' as it were....

[@MarkBryanRC]

Cheers, Barry! Yeah, I think the discharge rate is the key thing here! If only they would quote it on NiMh batteries, too! 😉👍

[@rascalracing4428]

Good info! Did you try lipo?

[@MarkBryanRC]

Thanks! Yeah I tried Lipo before and it went 1mph faster, but LiPo's are not allowed in this class of the competition. Cheers!

[@peteuncle2935]

Higher MaH batteries do allow more current and therefore power under load, if they have the same discharge rating. Let's say A 2000mah 20c discharge battery can supply 40A of power. A 3600 20c discharge can supply 72 amps. You need higher current to supply the power without voltage drop, when using geared up, high power motor combinations. That's why lipo batteries are so good, they can supply much more current, sometimes over 100c rated, which means much less voltage drop under load and more speed and more power.

[@MarkBryanRC]

Hi Pete and many thanks for taking the time to share your thoughts! Yeah that makes a lot of sense to me! I need more power (said like Jeremy Clarkson!!!) 👍 It would be a lot easier in the brushless/ lipo class as those batteries are much more reliable in terms of current supply! Thanks again! ☺ 👊👍

[@peteuncle2935]

@@MarkBryanRC i have put a wattsup meter on one of my brushed Tamiya cars, and under full load it was drawing nearly 80amps from memory. Probably way more than a 2000mah NiMH could deliver for any sustained time, like a speed run for example. A high discharge 5000 NiMH would be much better if your can find one if that's the way you want to go.

@@BasBoyRC No thats just nuts the higher the mAh just means longer run time and weight.

@@beandean356 Try watching the video properly, the first battery was newer but lower amps. Then he put in older higher amps and it went faster. My statement was for that. Higher amp batteries have longer run time and less drop off.

Batteries defo make a difference. We have noticed the difference massively whilst doing all our speed runs, but all our batteries have been LIPO. What i find bizzare in this test though, is the fact that you would think a lover MAH battery, would be lighter and therefore the car be faster 🤷‍♂️

[@MarkBryanRC]

Thanks, Tibs! Seems like the answer is pretty unanimous, thanks for sharing your experiences, too. I don't think weight has much effect on top speed though mate, but it would certainly affect acceleration and braking! Cheers, buddy!

[@leehurst6922]

Hi mark. The mah rating won't make any difference to the speed other than lower mah are lighter. It's the voltage that matters

Not at all mate! Hi Steve and thanks again for the batteries, they will definitely be put to good use. I wonder if it's because they are so new, they need a few charging cycles? I ran the 1800 NiMh you sent in my Agrios TXT2 and it performed way better than expected and the run time was also good. Maybe I should have used that in my test? I just went for the most mAh. Anyway, it was worth a try and interesting all the same! Cheers mate, enjoy the long weekend! 😎🙏👍
