Castle 5th scale
 

Don't know if I am late or not but thought this might be of interest. Castle showed off their 5th scale stuff at iHobby. 8s to drop soon with 10s a little after that.

Gonna have to start bugging the wife to get me a Baja 5b for Christmas now! :lol:

1/5 electric? Yes please!
 

As for my self I knew about a "big" esc, but I did not know anything about a 3 pound motor and, not to mention, the conversion kit for the 5B.

So, all in all great news and 1/5 electric is back with a vangeance.

German FG had a 1/5 scale electric some years ago but the car was quickly discontinued - if I remember correctly.

Maybe FG will release the car again? :yipi:

Sweet...the motor looks big enough to power a small car!

monstrous.....wow.....
Can't wait to see what people start putting these motors into....:yipi:

That's a 2028 motor -- using the same scale as our 15xx and 17xx motors.

It's a beast.

Our test Baja goes 0-50mph in about 2 seconds. Tires are a big problem, as they are treadless after about 5 minutes of runtime on pavement.

Fun fun fun!!!

This puts a smile on my face! :yes:

I LOVE the metal casing/heatsink that attaches to the chassis! I've wished the MMM was like that for a long time. It looks great Mr. Patrick! That motor of course is huge!

Sure would be different in a 4WD...

Yeah... Tires would last 6 minutes, and it would do 0-50 in 1.8 seconds. :lol:

Patrick,

The article said the Mamba XL is available now and the motor and mount are coming in a couple of weeks, I've gone looking for the ESC on your site and your resellers with no luck (aside from pending orders but no stock). Is it actually on the market?

I saw this setup at AUVSI and I've been itching to setup my Baja 5T with it ever since.

Patrick it looks awesome! I can't wait to build one my self, I have heard that it puts so much power out you can do burn outs and literally burn the stock tires of the Baja in less than two minutes.

Castle always does a great job creating new things for the hobby!

Front and rear mechanical brakes?
 

Does the 5B need front and rear mechanical brakes to stop, or does the default rearbrakes provide sufficient stopping power?

Thanks!

Best Regards

GreatDane c'',)

Rear motor braking worked fine on mike's 5B

( sorry for my bad english)

estimated selling price?

There will be discounts for those who Pre-order?

possible date for the purchase?

tanks in advance Luca

Wow. I'm actually turned on by this.

sold my castle powered revo and brought a baja now i want this!

pat you've done it again my poor wallet

thats going to be a sweet setup for my losi xxl:whistle:

does anyone know the KV of the motor CC was using in their baja that 8s setup?

I think this would be an awesome conversion with the Castle ESC and motor, maybe one day I'll be able to afford it: http://www.fgmodellsport.de/FG-Inter...-layout_e.html

Honestly, if Castle is having issues with people melting MMM on 6s on 1/8 scale trucks, im scared to think of the kind of smoke/explosions are we gonna see with 8s powered systems in Bajas?

Why? Its a COMPLETELY different ESC. Don't you think they've been taking notes the past years?

You seriously doubt this beast?

Looks like the original Mamba Max on Steroids!

Then I guess you'll have to miss out on all the fun. :na:

hopefully the shaft of the 20er motor is 10mm as this is the standart in big scale models.
lehner 30er models and the plettenberg bolido are also with 10mm shafts.

8mm shaft on the 20 series motor. The "Neu standard" for their larger motors. :)

So which company will be the first to make 8mm to 10mm sleeves????

well ... very annoying. i don't get it. there is an established standard. it makes no sense at all to deviate.
each to their own. imho its just not really clever.

rhylsadar

dam, 10mm is what all my 5th scales have. all 5.

I don't know that you can really call 10mm the "established standard" on 1/5 electric. I don't honestly think there is such a thing as a 1/5 electric "established standard" to be honest. It isn't as if there has been some booming electric 1/5 market for the last X years. I suspect the Castle system will establish the standard, as there simply isn't any other 1/5 systems in existence as far as I know? Sure, people have used some expensive HV ESCs and large motors intended for the boats or planes initially(myself included), but in terms of a dedicated system, Castle is the first and therefore will be the established standard. On a similar note, I have a full range of 8mm bore mod 1.5 pinions - not sure if such a source exists for 10mm bore pinions(and this would also limit the available size at the small end as well). It is also far easier to make a 10mm to 8mm bore reducer once for all your pinions than it is to ream out all the hardened pinions to 10mm.

huh? all bigscale models i know of use 10mm pinions this ist the size of the clutch used on zenoahs and similar engines.
the plettenberg bolido is explicitly a car motor. and the big schulze escs do very well in many big scale conversions. those escs and motors are sure intended to be used in car models. of course the "market" may not be that big yet. and to be honest i am pretty sure it will stay much smaller than the 8th scale market even after the entry of the castle system for different reasons. but we will see.
i know you have 8mm pinions. thats nice.
however there was imo no need at all to go for another standard.
10mm would simply have been compatible to the pinions etc already existing.
anyway now the things are set and we will adapt to the realities. no big deal.

Zenoah makes gas motors - not electric. Many/most 1/5 conversions that make use of the clutch may use 10mm shafts to be compatible, but that is an adaptation rather than an established standard imo. Where do you get a 10mm bore pinion or a selection of them? I know I chose 8mm for my pinions based on a couple reasons - 1st, I prefer Neu motors and the 22 series is a nice choice for 1/5 scale - these motors happen to be available with an 8mm shaft(not 10mm). Secondly, a 10mm shaft would inherently limit the the tooth count on the low side, which forces a higher rollout - works on a gas powered Zenoah, but in sensorless brushless, to much rollout leads to cogging at startup along with excessive heat - 8mm allows plenty of shaft strength and magnet adherence, while also allowing reasonably small tooth counts to be used for greater reduction. These to reasons along make 8mm shafts make sense in my eyes. Again, it is also easier to make a sleave for smaller bore pinions than it is to bore out each pinions used, so it makes sense from this standpoint as well.

^^ All good points.

We decided to go with an 8mm shaft for simplicity reasons -- an 8mm bore bearing handles the RPM better than 10mm bore bearings, and generates less heat.

Partick - Please could you check your PM - I need some info for the article.

I tried calling a couple of times but got Lee, Thomas, Linda's VM - Thanks

Thanks for those... The rotor pic is my fav...

How many HP is it putting out?

A any pics of the conversion kit assembled and apart? Assuming its CNC machined and black annodized vs stamped.

That is one big Caterpillar motor.

i see the point with the possibility for higher gear ratios. thats true. and yes of course in the US where the neu motors are that popular and the 22 series happens to have a 8mm shaft. of course that is reason for the US market.
however all the people with their mcd's, FG's, hurrax's etc have 10mm pinions ready in their boxes. anyway the 30 series lehner and bolido put 10mm shafts on their big scale motors to be compatible to those people. as there are conversion kits especially for the MCD and FG's this is sure an argument. anyway its not that important.

@patrick
i do not see the rpm-argument. in those big scalers you would go with a very high gear ratio that you need high rpm. between 20' - 30'000 rpm is more than enough for the usual big scalers. and thats not really so much right.

anyway we will see if what factory built 5th or 6th scale electric cars will come in the future from the producers. but to that point the main bulk of people will be those that convert their exisiting petrol models to electric.

The only reason I see to go with a larger shaft is if there are strength issues. Otherwise its preferrable to go with the smallest shaft neccessary for wieght reduction and gearing flexiblity that Mike mentioned. 8x16mm bearings are also very common and inexpensive. (making an assumption on size)

I don't see any reason why castle should use a thicker, heavier shaft just because FG throws a 10mm pinion for a gas engine in the box. Sleave adapters are simple items anyway, and a cheaper and easier solution overall. I'm sure Mike could pound them out asap like his 1/8/4mm/5mm adapters. Novak in a year or two. lol

That or just buy the right 8mm pinion you need. Who says the one in the box will be right anyway?



Anyway, motor and esc looks tremendous. GJ as always Patrick

I would say stick to 8mm shafts and use bore reducers for those with 10mm pinions. That way, no one gets left out: use 8mm pinions directly or use a 10mm-8mm sleeve/reducer if you have 10mm pinions. Pretty simple IMO.

So Patrick, when are you getting into the e-motorcycle/bicycle market? Any more similar increases in motor size and we'll have affordable really big scale conversions. :smile:
