:)I'm not sure whether to hold off for the moment or not as rumour control say's Losi are developing their own 1/8th electric vehicles. If however they're someway off, more than likely, I'll go with the conversion.
As the Neu motors seem pretty hard to come by has anyone experience of the Hacker brushless motors, how do they compare on quality & price?:)

Purely from an outsiders point of few (well an outsider in as much as I've only just come back into RC) I'd jump at the chance to do this class if it became big enough.

I love the 10th scale off road but the little experience of rallycross I have had was great, but the noise, oily mess etc is a little bit off putting. I was looking for something that was a little different to the already noisey and oily Motocross so for me and i'm sure many others 8th scale electric would be great fun.


I'm certainly going to be watching this development with interest and if it takes off i'll be putting my orders in.

:)Well the Losi electric 1/8ths seem to be a bit of way off so I've got a Tekno V3 Losi 8T conversion coming, Neu 1515 -1Y Hi Amp motor, Flightpower lipo's and waiting on the Castle Creation Mamba Monster Max V.2 esc. All going into a new Losi 8T RR:)

:drool: looks the part :thumbsup: keep us posted please:woot:

Yep - waiting for a Mamba monster myself but there seem to be a few worrying stories over on RCTech - may have to have a bash with a Tekin R1 or Mamba Max for the 4cell Im working on....

Pete

give the Novak HV Pro a go, I noticed they were no. 1 and 2 best sellers on the amainhobbies website :).

used to be indecisive but now I'm not so sure!! I was waiting for the CC Monster esc and then found out it's not waterproof which with our weather is a bit of a bummer so I'm looking at going with the MGM ComPro 16018.
The esc is the only thing thats holding things up.

Is the compro actually waterproof?

In terms of the Novak stuff I prefer around 2000kv for 4cell so nothing that suited for me.
What have you been running yours on - 3 cell 11.1v?

There are going to be an awful lot more suitable speedos available soon as I know at least 3 companies that are working on them.

Pete

As soon as the mamba monster has been produced any store that stocks Trakpower/FlightPower will be able to get it in for you.:)

I don't why Novak have gone down the high K/V route. I've been running 14 NiMH cells on a HV4.5 - so absolutely loads of revs - in an E-Zilla. The top speed is very high. I have only used it for bashing, so probably haven't really stressed the ESC, although I have lapped a track without any thermal issues. As Novak says the HV4.5 isn't suitable for racing. But I would have thought the 5.5 / 6.5 would be pretty good with appropriate gearing, although they are both way over your target of 2000K/V. Why are you thinking 2000? Perhaps this would offer smoother bottom end power delivery than a low geared high rpm set up...

so whats needed, how you mount the motor?

motormount:p

If using the Novak motors, then Novak supply their own heatsink motor mount that bolts to the original engine mounting slots via an (included) adaptor plate.

If you want to use Neu or MTroniks motors or whatever, then you are best buying a proper motor mount for your car from someone like Mike at RC Monster.. That way, you can mount the Novak motors too! (and the look bling) :)

In terms of motor mount the vast majority are a replacement for the centre diff mount on one side - basically extends out to allow the motor to mount. This is how the RC Monster and various conversions are done as well as the Caster. The only diference in layout tends to be that some have the motor to the rear of the chassis and some to the front to give more room for the cells.

The Novak and Tekno systems use a motor holder that clamps the moptor and attatches to the chassis in the same manner that a nitro mill would do.

any links of where to get one?

To get one of what........?


Mark you seem to have the ear of Trackpower - could you check if they are planning to bring in the CC Monster Max and Monster Max Combo(with motors)
....and why dont they bring the Mamba Max esc in on its own...
at the mo there is no choice but to bring them from the US or buy the combo and flog the motor..

Pete

sorry, the motor mount (not novak) for koyosho mp777 sp2


from this qoute yes they are ill find out bout speedo

Mark - that sounds like they are not planning to stock them but special order?

http://www.rc-monster.com/proddetail...rcmkyoshomount

Pete

not that means it will be in stock at trakpower hq and any trakpower/flightpower dealer will be able to get it fronm there as soon as stock is available from mamba, also thay are brininging the 10th speedo in on its own too
just spoke ot em:thumbsup:

Mark, i would recommend the conversion kits that Dan produces across at RC Product Designs, info here http://www.rcproductdesigns.com/E777.htm

It would cost less than £100.00 for the conversion kit, then you just need to add the electrics.

Have you been having fun with your 1/8th beast yet jonathon :thumbsup:

Bloomers ran it at Southport, but we were having problems with tekin speedo, so it did not really show it off at its best, so i will not be using it until my Mamba Monster arrives from the states.

keep us informed :D

JOnathon - what speedo R1 with cap I take it? I was bout to order one up to try but will wait to see what you reckon to it....


Pete

Its the R1 pro fitted with a 25v 2200uf cap and i run a fan onto the solder posts as these are the heatsinks, i think with holes drilled in the case it maybe more upto the job.

But its always in the back of my mind that its a 1/10 speedo running on double the voltage and pulling a heavy car. Were as the Monster is designed from the ground up for 1/8 cars, and the guys now using the rev2 speedo's are getting good results.

There a good thread on RCtech about using the R1 in 1/8th which proves interesting.Seems that the Fets are 30v so safe in that sense.

The only other thing is to run a external bec by the sound of it.

Yep - V2 Monster seems ok after a few scare stories.

Pete

Already use a external bec ;) and have read the threads on rctech and the tekin forum about using the R1 in a 1/8.

Some people get good results with them, if you get one let me know and i can send you some caps if you are running 4s.

Cheers Jonathon - I will let you know.
I am trying to test a few set ups that I can safely recomend to ppl for the EX-1

Pete

I think the Monster will be the ticket, and also the revised Novak speedo if they have solved the thermaling issues, and they produce some lower Kv motors.

http://www.oople.com/forums/images/icons/icon7.gifAccording to MGM the Compro is available in a waterproof version as most of their esc's, those that have them rate them very highly. They are expensive compared to the Mamba but with our weather if I can get a waterproof one I'd prefer it.

I went with the Tekno conversion as it retains the clutch and mechanical brakes which will presumably mean the esc doesn't have such a hard time. I realise that a lot of people will say why do you need a chassis just buy a motor mount and battery tray but I liked the idea of keeping the brakes & clutch and as the 8T RR donor vehicle is brand new the unwanted parts will go in the spares box for our nitro 8T's.http://www.oople.com/forums/images/icons/icon7.gif

Nice article in this months Radio Race Car International. They've put a HV6.5 in an RC8 using the Novak conversion. They raced it in Coventry, sounded like it ran well, running along side and just pipping the nitros. Comfortably managed a 10 minute race with two Reedy 5000mah LiPos. The conversion sounded pretty straightforward, a dislike being the motor fan clashing with shell. They got round this by applying heat to stretch the shell out a bit.

Tested mine for duration last night with the trakpower lipos.

14.8v 25c 5000mah did 17minutes round deerdale astro, geared 15/46, the car was really quick.

Will be trying 7400mah 14.8v 25c tonight or tommorrow geared down 14/46, will report back later..

Temperatures were perfectly ok: motor 150 , speedo 140, lipo 120 after the 17 mins.

I think you will need a trailer for that size lipo :p 7400mah is going to be big.

It is big! but trakpower are working on it ;)


I think ive got my gearing pretty much spot on now:

14/46 with neu 1512 2.5 d/f

The 7400mah 14.8v cells lasted 25 mins, the car was still very quick

I have turned the throttle curve down to -22% and brake to -90% !

Its all going realy well now, looking forward to showing a few of you at stotfold (if they let me :eh?:)

in large scale oval we use a 1/8th rallycross style car on road tyres and a salloon style body. As luck would have it 99% on the people racing use one kit which is the ftx street racer.
last winter i set about converting one of these to brushless and do some testng with the intent of racing it this year in the series against the nitro,s.
i know rallycross and oval are different but in oval you are on full gas more than off so the draw on fuel is high.
so with loads of data on pc from years of nitro cars racing and a venue to test at i started testing. ive used different motors, speedos direct drive, clutch and speedo brakes and mechanical brakes. my goal was to match the speed of the nitros not to be faster all before the series started.
findings:
1.speedo brakes had big effect on my run time.
2.direct drive with the pinions available albeit hardend lasted about 10 runs.
3.anything less than 4cell lipo everything got to hot
ive ended up using a waterproof boat speedo 4 cell lipo and a tekno clutch but 3 shoes and only 1 clutch shoe spring this acts as a 10th sliper clutch and is great.
ive used this setup for 7 round of the series so far and its cost me no maintainace and it gave me a track record this sunday.
i have just built a similar set up in a rallycross car for rallycross use and i am going to test it only difference will be to reduce the gearing as the rallycross tyres are bigger
brushless speedo and motor for less than £100 cheeper than replacing my engine for this season.

On my EC Xray XB8 and AE RC8 I'm currently suffering a bit from primary gear wear with the Novak pinions.. I have heard a Plastic spur gear helps a lot but the only one I could find was from a Thunder Tiger EB4 S2 RTR, although the dimensions are about right and the number of teeth at 46 are perfect, the holes where it mounts to the diff are too close together for the Xray and RC8...

Has anyone found a plastic spur that is a straight bolt on??

Tom

The only commonly used one is the Kyosho item.
RC Product designs do a modded version specifically for the RC8 though with a bit of reading I would assume you could mod one yourself.
http://www.rcproductdesigns.com/EigthScaleParts.htm

Dunno about the xray one though:(

Pete

The Kyosho version is easy to cut down or modify

KYO-IF148

:)

James - does it fit the xray as well?


Pete

It will fit if modified..
