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

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.

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.

BL_RV0 · 06.15.2009, 09:08 AM

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. :)

nitrostarter · 06.15.2009, 11:01 AM

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.

RC-Monster Mike · 06.15.2009, 11:06 AM

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

nitrostarter · 06.15.2009, 11:13 AM

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.

RC-Monster Mike · 06.15.2009, 11:20 AM

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.

nitrostarter · 06.15.2009, 11:37 AM

Understood!

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

Thanks Mike!

Ryu James · 06.15.2009, 11:58 AM

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?

Ryu James · 06.15.2009, 12:24 PM

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.
