makes me wonder how much mikes pinions will be when hes done?

Hopefully cheaper... I will say that the ones I got are huge, must be almost 1.5" long. I will most likely have to trim them down, but the added length is handy as I can fine tune the motor position.

Let me know when....They have a lot of nice surplus things :yes: that will be good to use.

I already called dibs :lol:

We(myself and partner in crime Eovnu87435ds) both got selcted for the internship program due to our background in electrical systems. Pretty sure we get to work with the AEGIS system and the Radar testing equipment... Robotics does have its perks :yes:

I think the right motors for 1/5 scale are the big Neu 22xx, Plettenberg Bolido and the Lehner 36xx. I also think Astro Flight has some low Kv big inrunners too and when the appropriate ESC comes out they should be a good motor too (Actually they are really low Kv and might not work).

It weighs right around 20 pounds or more, about same as the stock rtr but with a much lower CG and tons of power. Price wise I wont mention what I have in it, cause I get sick even thinking about it...lol. You can do one without spending 5 grand though.

I like the looks of the bolido, but do you know where I can get more info on it? Its neat that its a direct fit for an fg pinion which is also mod1.5 and makes life easier:lol:

Here you go http://www.icare-rc.com/plettenberg_pricelist.htm#cars

good luck on that, its a tad spendy:tongue:

Is there a target price for the conversion kit?

Harold pointed out the place to get the motor and the pinion can be found at https://sdp-si.com/eStore/, click on metric go to spur gears and use the drop down boxes to select the following: 1.5, With Hub & set screw and the bore size.

Gotta watch them... I ordered 8mm bore 1.5mod 12t pinions for my baja and selected w/hub and setscrew and they showed up without any setscrews, or the drilled/tapped holes that a setscrew would go into... Good thing I have a drill press...

Good to know, but it hasn't happened to me yet. Thanks for the heads up. Did you get the carbon steel ones?

I just got a $60 order from SDP-SI today, including belts, pulleys, and a gear. Everything which was supposed to have a set screw did. Did you recheck your order to verify that you ordered the gears with the hub/set screw and not hub/no set screw?

Yup...

I double checked the part number on the invoice and packet to the online info and I ordered the correct thing. Must have been packaged wrong. No bother really. The 8mm bore mod 1 pinions I ordered cam with a setscew so small I had to use the pointy end of a dental pic to unscrew them. What a joke. I will have to drill them out and tap them for m4 thread as well. I may drill the mod 1.5 pinions out for m5 or m6 thread, they will need some strength and the 1521 motor shafts are 8mm...

It's true, some of those set screws are extremely small. Thankfully we have drill presses...

...looks great...makes me reconsider doing my own one...its the size that kills me though...i want the HPI Baja in like a 1:10 size, or kinda like between a 1:10 and a 1:8...These comments are not directed at anyone in particular and in no way should be misconstrued as a complaint or a request :D

any updates on this kit. i have a baja that just sits here and would love a brushless in it lol.

Lol, it's funny that this brushless motor costs 100 dollar less in the EU. Mostly all things are cheaper in the US than in Europe..

That Baja is insane, I can't wait for a electric conversion to be on the market for the Baja. Then I might get one.

whats the latest on this baja conversion? any videos yet? i would really like to see some detailed close up pics too.

would a neu 2230 fit in a 5b or 5t or is it too long? or too much power anyway?

Video video video !!!!

A 2230 may fit, but the 2215 can push it beyond what the steering can handle.

There was a guy running his baja on a 1915 and 9S lipo with great results.

EDIT: Found the video: http://www.youtube.com/watch?v=b9cp_d71MkI

I've seen that. Impressive for an 1,800 watt motor but the engine in my Baja is much more powerful than that. A 2215 is rated to 5,000 continuous watts, hard to get a gas engine to reliably compete with that.

Yeah, there are very few gassers that small that can produce 6.7hp cont.

The 5000 watts rating is for airplane with good airflow. I see a lot of people going by those number not realizing it's not for cars. In a plane where you get good airflow you'll be able to attain such a number and the AMP usage in a plane is not like the AMP usage we car guys see. We see burst, many bursts to be exact, which will sometimes go over what a motor and esc is rated for.

Gas engines are fairly easy to modify for the power. However, BL is just much more impressive.

The 19 series motors are fairly torquey motors! They produce good numbers but there efficiency isn't as good as the 15 or 22 series motors though. I've seen people use the 1910 and 1912 series motors in large boats(power hungry in nature) very successfully!

O and not to mention, a Neu 19 series is like $200... versus $400-500 for a 2215...

The baja conversions are in the final stages - had to make some tweaks to ensure proper fitment on the stock type chassis(CF is slightly different it turns out). The current motor plate accomodates the 22 series Neu, but I will also make additional motor plates to accomodate different motors(a 1521 may Git'R'Done in certain circumstances, and a 1527 is almost as powerful as the 2215). I will have a range of pinions for these conversions as well (15t through 22t for now) - hardened steel with an 8mm bore and 5mm set screw(will offer bore reducers as well, but recommend an 8mm shaft on these beasts). Target price for the pinions looks to be around $12-$15. the complete conversion kit price is still TBD, but will be a very small fraction of the cost of the conversion as a whole for sure.
RCDriver will be putting some time on Coolrunning's truck in the near future as well. :)

Awesome! I'll be looking for that issue!


Mike: any chance of 8mm bore mod1 pinions? I'd like to try a 1521 in my LST2 but can't figure out the pinion situation.

1521 motors come standard with a 5mm shaft. 8mm is special order. No plans for an 8mm bore mod1.

Ah! I see sir. I have my 1521 from boating and they use the 8mm shafts. Thanks for the answer, and you can ignore that email I sent as well.

My follow-up question is do you think there is enough material there to have the 5mm pinions drilled out to 8mm and them still be strong enough?

Thanks Mike!

I may have to get that collet from TDR and bore it to 8mm, and then run you screw on pinions.

2 major problems with drilling the existing pinions:
1) - they are HARD. they would need to be annealed, drilled and re-hardened
2) - they only have 10mm of total material at the set-screw area, which would only leave 1mm wall thickness after boring to 8mm. This is not enough meat.

You probably could make a collar to slide over after boring and make it work, but it will be a bit of work no matter how you slice it.

Understood!

I think I'll try the TDR and your screw on pinions. On have the shaft turned down...

Thanks Mike!

I wouldnt hold you to it cuz i know how these things go but is there any kind of ETA as to when the conversion might be available by conservative estimates?

while we are talking Baja's....does anyone know if HPI will EVER make a 4wd version? i cant believe they are so dumb to not have done this already. they could double their sales. imo, the only reason anyone buys any other brand of 1/5 is for the 4wd. if HPI offered a 4wd baja they would steal the business from FG and all the others here is the states. it would be done and over. not even a question. of course, as long as the 4wd version could make use of all the many hop ups available for the baja 5b. if they had a 4wd my decision would be alot easier.

Darn it - I was hoping for that review or in fact to actually covert Greg's Baja!

Oh well...

On the 4wd issue, I think the design of the chassis and layout of components (in the natural nitro state) is such that running a belt or drive shaft from the tranny (which would have to be completely reworked) down to the front end (which would also need completely reworking) just isnt possible, too many things in the way. If HPI ever released an electric version.... stratch that, they just wouldnt due to costs envolved for the electronics- cant see them selling a roller version and they probably couldnt sell an E-baja as the price tag would be horrendous... my 2c anyway.

Hmm, single 1527 in a baja? I may have to try that as I have a 1527 2y. With a 12t pinion and 10-12s lipo it would be a decent setup. Maybe I will give this a try as it will be easier to setup than the dual 1521 setup I was planning. Plus I can make my own mounts easily for a single motor.

The design of the Baja really doesn't lend itself to a clean 4wd setup. I've seen people running belts off the spur gear up to the front but IMO it looks tacky. The Baja is a blast to drive, partly because it's 2wd. A 4wd 1/5th truck would be sweet, but considering the 2WD 5T costs $1300, I don't want to think what a 4WD would cost.

A single 1527 should do the job just fine, I don't really like the length of them though. Too much weight hanging off the screws and front endbell coupled with the forces that are sure to be exerted on it by bashing it I'd rather have something shorter or have some support in the rear. Dual 1515s, 1521s, or 1915s would be a sweet setup. I know dual motors aren't as efficient as a single setup and it doubles the chances of a failure but it's so much easier to get the power you need by just adding another motor rather than making an ESC that can handle a massive motor.

I think the "too much weight hanging off the screws" is more paranoia than legit concern to be honest. The screws are held in tension and friction is really what holds the motor in place(from the screws pulling it against the mount). The actual amount of force required to pull an m3 screw out of even aluminum is measured in thousands of pounds and the screws themselves are not the weak link(it is the threads in the aluminum that will fail first). If you have sheared a screw in a similar application, it was likely a low grade screw that was loose to begin with. :)
