Losi Tenacity DB Pro - owners

[Graeme - Edinburgh]

Thought I’d start a thread for DB Pro owners as there does not seem to be one...First proper bash at the weekend just outside of Edinburgh.

Keen to hear from other owners and especially around upgrades you've done, as a few things I'd like to do to the car - especially the wheels. 

 

So far i've ordered:

 

New servo and servo horn

RPM skid plates

 

Also so considering other detail parts, as I love how this car looks as well as drives.

Great pic that, scenery and buggy look really nice. I'll be interested to hear how you get on with this one, as I've been looking at them a bit lately, like a nice DB.

[Graeme - Edinburgh]

Today's spot for some high speed runs...

 

 

[Graeme - Edinburgh]

I've got a technical question from a newbie. The rear wheels on the car seem to toe in somewhat and not sure if that's just how it's supposed to be, or if it's adjustable or if there is some sort of issue here. Car seems to run ok though. Welcome any thoughts on this?

So far so good. Loving the car. I did a lot of research before finally settling on this one. Had these on my shortlist...

 

Losi Rockrey

Losi Lasernut (I love this car and would have got it, but it's reviews sucked - poor build quality. If they make a v2.0 - i'd buy that)

Traxxas Slash

Axial Bomber

 

The car is fast, but i like how i can control the speed if i want less power for doing stuff on steeper terrain etc. So far the build quality seems really good, as this is essentially v3.0 of this car. 

 

3 battery packs in and no complaints.

Where abouts was that mate ?

as for the wheels some cars have toe in and others toe out so its normal

Good to know. Wasn't sure if it was a design feature, or if there was something not quite setup right. Out of the box i had to adjust the front wheel alignment, as that seemed totally off.  Will post a map on that other thread. 

[Graeme - Edinburgh]

Bad news! The DB Pro is in pieces...unfortunately, and like the Lasernut, the DB Pro also seems to suffer Diff issues. I've only had the car a month and used it 5 times; and the Diff has failed. Oh, and I also lost a screw from the drive coupler, which was just gone - clearly was not secured very tight. 

 

I'm going to need to shim my Diff. Can anyone give me any tips on how exactly to do that? About to watch some videos on the subject. 

 

Thanks, Graeme

Got mine today. 

 

 

Already rounded the pinion set screw when i tried "converting" it to 3s, so yay me i guess.

 

I'll keep the "big" pinion on, currently looking at heatsinks to keep the motor alive. 

 

Two sets of new wheels coming (one set road tyres, one set offroad), 17mm conversion coming, heatsink coming (soon), potentially new steering assembly (bellcrank etc). 

 

Not a bad list considering i got the buggy only today. 😞

That's a great list of upgrades. You'll have fun with the car - it's rapid. As I'm discovering, just be prepared to get the tools out.

What wheels / tyres did you get? I got a set of Proline Badlands MX SC 2.2/3.0 M2 Tyres Raid 6x30 

[Graeme - Edinburgh]

Has anyone else had an advisory from LogicRC regards the ESC mounts?

I was actually a little disappointed today, ran it on 3s with the big pinion installed, didn't feel quick. 

 

Admittedly, had a few issues binding the radio and might've gotten the throttle calibration wrong, will do that next time. For the time being i have to wait for the heatsink, the motor won't take the 17t pinion + 3s. It definitely was slower than the Typhon 3s today. Which wouldn't be at all surprising, it's quite a bit heavier and runs a "smaller" (3150kv to 3200kv in the T3s) motor. 

 

Indeed already looking where to go from there, the buggy certainly looks cool (main reason i bought it - reminds me of my DBXL-E 2.0), but it isn't quite "there" in terms of where i'd want it to be in regards to speed.

👍

 

edit: as a disclaimer, these will only fit if you converted to 17mm hexes.

Just checking you were not running at 50% power, as switch on the radio has 50%, 75% and 100% power options - i'm sure you were running it on 100% 😉 Bummer re your pinion. 

[m4inbrain]

Yeah, did run on 100% 😉

 

Same radio as my DBXL-E, so no confusion there. Slightly unhappy with the steering as well, out of the box there's a pretty decent amount of slop. I'm certain i can tighten the servo saver down a bit to get some of it out, but never happy to see that kinda wobble.

Servo a popular upgrade on this one. I've got one, in the midst of installing it once i fix my Diff. 

[m4inbrain]

Yeah, did do some research, hence me opting for a metal steering assembly. Since i run exclusively 3s, probably gonna look at the HD diff cups too.

[m4inbrain]

Well.. 

 

Say hello to my factory 17t pinion. 

 

 

Atrociously assembled. "Change the pinion if  you want to run 3s". Sure i do, but not only did the set screw immediately round out, when i then drilled it out it still wouldn't come off. Turns out they slathered the motor shaft in whatever bonding stuff they used, leading to that because of course the motor doesn't come out with the pinion attached - you can't take a blowtorch into the buggy, and centerpunching it out while in the buggy doesn't work either.

 

It drives better than anything else i have currently in terms of handling, but i'm far from happy with it.

Horizon are ruining Losi. No one can convince me otherwise 

[m4inbrain]

Can't even disagree on that one. That said, my DBXL-E 2.0 was "by horizon", and that was literally flawless. Zero issues.

 

 

[mydoddy69]

Man these have dropped of a cliff in terms of quality by the looks of it, my old version would run 4s no worriers 

 

 

Was an awesome rc and one I regret selling if I’m honest, went like stink but didn’t like the rough terrain to much

Thought these looked familiar, I had one and agree entirely with that. Was unbelievable in my cul de sac however. Just wasnt good at the rough stuff.  Didnt keep it long enough to give a long term review..

[Graeme - Edinburgh]

So that’s my Diff re-assembled and back in the car. Now to setup my new receiver and servo. I’ve got the Flysky Noble NB4 and with FGr4 v2 receiver. So here is a newbie question. See the picture below. Trying to work out which plugs go where - Spektrum to Flysky. Doesn’t help they don’t use the same abbreviations. Tips welcome, as I really don’t know what I’m doing?

 

Thanks, Graeme
