I thought the same thing when I was looking at it today. But those side trays are removable, and kinda flimsy. That area is going to take some beefing up.
Its one heavy monster....

I also saw a few conversions with Lehner 2250 or 2280 motors. If you compare those motors wheightwise with Neu Motors you should have a good match for your car. An MGM 12545-3 ESC should also do the trick. Good luck with your project.

Did anyone watch the 1/5 MT vids from him? Impressive, I'd like to see the eagletree graphs off that. Here is his vid list, part 6 of the MT buildup really shows what brushless is really about. Hard to believe that truck is 20+ pounds

I've been enjoying those videos. I have never seen the gas version that fast and I never seen the gas version do wheelies like his does.

Yeah, that Bolido throws it around like... like a.... well.... something smaller. :lol:

Takedown 11.06.2008 10:28 PM

By the looks of it its not an FG at all. They have many copies of the original base models of FG like their MT's and onroads from the original batch that smartech now still produces. Its exactly the same as your model.

I hope you are not referring to my car - this is an original FG evo - the wheels are off a FG stadium truck to give it better traction. Over the years I have stuck to FG and MCD and avoided the clones. I have met owner of FG Franz and respect him for what he did for the hobby before all the clones came out with their stuff. However I have seen the clones and I think they are good value for money.

Mohan,
perhaps you can help me out. where did you get the pinion gear for your motor? is the motor shaft 8mm? HOw does that motor compare to the Neu 2215 motors or the Neu 1527? any ideas?

as far as the knockoffs, i agree with you. The FGs i can tell are much nicer. this smartech is exactly the one in that link you sent. the FGs chassis is much nicer with the cutouts to save weight. this chassis is just one solid piece of like 5mm alum. alot of weight.

The Bolido motor has a 10mm shaft which is grounded flat to 8mm on opposite sides - this is identical to the shaft output of the Zenoah engine. This allowed me to fit the FG pinion gears. I purchased the Bolido motor because of this as I was keen on having a choice of pinions from FG etc..

If you want to use a Lehner or other motor such as Neu you will need to fashion out an adaptor that will convert a 5mm shaft or 8mm shaft to a 10mm shaft with ground sides to 8mm if you want a perfect fit. I think with the high rpm this is important as you want to avoid vibration due to imbalance.

Personally I am a big fan of Plettenberg motors as they are multipole motors and develop a help of a torque. I know there are other forum members who have compared the KV rating of the Plettenbergs with the Neu motors and drawn their own conclusions but all I can say is that this Plettenberg Bolido will do anything a FG monster truck will do.

My setup is geared 23/40 and I believe you can go upto 25/38 max. I still have so much torque it is wasted on this gear ratio. It is geared for maxximum speed not torque but the motor is so powerful it doesnt care. I think if I install this motor on a Monster FG it will cartwheel easily and wheelie non stop.

I have never experiemented with a Neu 1527 or 2215. Here in the UK it is difficult to obtain Neu motors and it is easier to obtain Plettenbergs or Lehner motors from Germany. So it is the oppositie to the situation in the USA.

In the next couple of weeks I am going to install the Lehner 3080 in my MCD monster truck. This is motor is so huge it is the diameter of a 2litre coke bottle. With the 4WD I am hoping for impressive performance but realise that speed is not going to be its main asset. This motor has a 10mm shaft and I look forward to grinning when I can find the suitable Motor mount to accommodate the girth of the motor. Total overkill but who cares - I already own the motor and the speed controller to go with it. As I mentioned before it will hopefully run on 18S. I want to try and find out the maxximum limits of Brushless power.

I've seen more powerful motors around. In fact Hacker have a motors that is 50% more powerful than even the mighty 3080...

http://www.aero-model.com/motordetai...00/200&style=6

It's a 10000 watts continuous motors! The lehner 3080 have nearly the same rating as peak! Good luck fitting it though!

thanks for the info. for your next project check out this link for ThunderPower LiPo batts. they have 10s packs 5000mah. run 2 of those for a 20s or you could go all the way up to 9000mah in a 6s and run 3 of those. BAM! thunderpower makes the best packs imo. anyway, you have been bery helpful, as well as others. http://www.robotmarketplace.com/prod...me_series.html

Video
 
OK I made a couple of videos. It was a wet day and I could not push the throttle more than 20% of the range. However I did manage to get some videos posted.

Any tips are welcome on how I can improve traction.

http://i476.photobucket.com/albums/r...G39mphroad.jpg



This is the car running on a paved road at and speed gun showing 39mph. If I tried to go any faster the car would spin out of control.

This video shows how the car was difficult to control in a wet lane with lots of leaves to make things worse

I was reffering to Ryu James's onroad.

Ryu James 11.15.2008 01:16 AM

hey all,
i just finished the 1/8 schumacher. clocked it at 74mph. its a lot of fun. i wanted to use a 1509 1.5D but the wait was 6 weeks so i just went with a castle 5700kv. i am sure the Neu would be better but i am happy with it. here are some pics i promised. kinda rough right now. gonna "dress" it up a bit over the next couple of weeks with some upgrades. anyway, as mentioned i wanted to finish this first before moving to the 1/5 on road. so now i have a RC8T i am doing a custom build on and then it is on to the 1/5 on road. i still want to go with a Neu motor but i need to find somewhere to buy pinion gears with a 8mm hole. anyone know?

thanks bro.

Ryu James 11.15.2008 03:59 AM

does anyone on here know what the module or pitch of the 1/5 scale gears is? i ams ure they probably all run the same. the gears on my smartech look just like the ones on the FG. any ideas?

Arct1k 11.15.2008 10:03 AM

Mod 1 I believe

Ryu James 11.15.2008 11:33 AM

its not mod1 because i have a bunch of mod 1 gears for my truggies and they dont mesh up right with the gears on the 1/5. they are much larger than the mod 1.

mohanjude 11.19.2008 12:32 AM

Ryu James:

Can you take a close up of the 3 speed gearbox setup? Is there a clutch bell on it? I think you are getting the speeds because of the gearbox as I find it very difficult to gear a car for speed as well as acceleration without compromising battery life or weight.

If you have any pictures / diagrams of the pinion / spur set up it would be appreciated

the previous pages of this thread have pics of the 3 speed (page 4) on the 1/8 schumacher. it is a pinion gear. i am happy with how the thing drives though. it is insane fast both off the line and top end. any faster would be undrivable. it already is pretty tough to drive.

Wow , donated 5th scale
you must be a really nice generous guy.

Very interested in the power details, be sure to list where you got parts and stuff.

no, actually the guy that donated is a very nice, generous guy. :lol: i am a greedy bastard! :lol:

i am just finishing my RC8t build and have finished my 1/8 schumacher so now i can move on to the 1/5. however, Mohanjude turned me onto these 1/5 brushless setups that are absolutely sick in germany on ebay. plus i can get the complete setup (except battery and servo) for the same as what it would cost me to make a motor mount if i convert this one on my own. for basically $500 US plus $50 shipped you get the car, painted body, motor, esc, ARTR. just needs lipo and servo like i said. check it out. and check out their other auctions. so i am thinking of just getting one of these and then adding a more badass motor to it.

I have already got this car. The body shell is excellent. The motor mount looks like it will do the job. As I expected the brushless motor and controller are not upto the job of propelling this car to any significant speed. However I have got a big bad Lehner 2250 or 2280 just waiting to be mounted. Looking to power it on 10s. Hopefully it will be worth the effort. The car is a fraction of the weight of my FG aluminium car that is heavy due to the aluminium, hydro brakes etc..

RYU JAmes - did you actually purchase the car and receive it yet?

no, i havent bought it yet. but i could see that it would be tons lighter than my 1/5 too. my Smartech has a HUGE, thick aluminum chassis that weighs a ton and that one on ebay is alot more narrowed down. also, i figured for $500 that the motor and speed control would not be that great but thats ok. at least i dont have to do any modding. just buy a better motor and esc like you have done and throw it in.

post some pics and some vid of yours when you get it finished putting the better parts in. would love to see it.

florianz 12.10.2008 09:33 AM

what about a big outrunner motor? in general high efficiancy, and lots of torque which is recommended for such a big car.

there are many companies around, producing high quality outrunners.

these guys here http://www.torcman.de/ have for example a monster which can pull up to 4000 watts...

or e.g. flyware, I just have ordered one of their large inrunners (8pole), as the feigao-clones' magnets break...

here's an outrunner that takes up to 45 volts: http://www.flyware.de/wde/erp/shop.php?navid=4

65 mm of diameter should provide some power :whip:

they also have nice motors (some are inrunner-looking outrunners), but probably too small: http://www.mvvs-electricmotors.de/index.php
