Yeah, I managed to win the auction on Mamba Max 7700 I't should arrive tomorrow, also I've bought 16/48 pinion today for it, hope it will be ok.
I was wondering, since my motor will have more power and the pinion is smaller could I use bigger wheels? I have set of 140x56 wheels and I'm curious how it would behave on them

So if you decide to go that route, I would recommend upgrading to alu coils

Bigger wheel means coil damage since they are taking all the impact on jump landing (more clearance = less body hit)
So if you decide to go that route, I would recommend upgrading to alu coils

RE: Official E-FIRESTORM thread
Hi guys, I just have to share with you my first experience with my new brushless motor [link=http://www.medusaproducts.com/motors/036-V2.htm#MR036050XXXX-3]MedUSA MR-036-050-4800V2-3F[/link]. I running CC MambaMax with 5700kV motor (17t pinion gear - but I've learned later on that it is more to 19t as I've 2,8'' wheels) and it goes really hot quite fast - so I decided to find "real" 540 motor as CC one is 380 in 540 can (shame on them!). So I ordered MedUSA and guys - it's huge difference! Firstly I changed pinion to 19t (still 2,8'' wheels) and tried appx 10-15 minz of full throttle - break - full throttle on pavement and grass too and temerature? 50°C - lukewarm motor! Second thing I've tried was low speed cruisin' With CC 5700kV it was pain when You wanna ride up hill slowly and with MedUSA it is very close to sensored systems - off course it can't beat sensored systems in smooth slow motion! Once I'll do more test I'll let you know

+1...bigger wheels = more problems, but once you try them it's really hard to go back to smaller ones. I've [link=http://www.wheelspinmodels.co.uk/item/TRX-3669-Traxxas-Talon-Tyres-Pre-Glued-On-All-Star-Chrome-Wheels-12mm-Hex-Fit-__271f/]2,8'' wheels[/link] and I love them - much better clearance and together with Gyro and stiffer rear shocks they are incredible. Also stiffer shocks helps hold motor not touching the ground during jumps. Just have to be more careful/easy on throttle when bashin' and you can avoid a lot of troubles IMO

Hi !
Do you know if it is possible to put a motor heatsink (without cooling fan) on an E-Firestorm ? If it is could you please let me know which kind of models ? Isn't it possible to have pictures ?
Thanks in advance.

thanks red!
Well today I've tested my new mamba 7700! on 16Tpinion and stock spur it's crazy faaaas (much more than 50mph ) maybe I'll post some movie later. But Ineed to gear down to 15T Ithink because motor after ride is hot.
Added photos of motor and the car after some dirty ride

RE: Official E-FIRESTORM thread
I have a stoooopid question for you guys...
I just bought the E-Firestorm yesterday morning... I had a bunch of 3s/11.1 Lipo batteries from my airplanes and figured I'd try one of those instead of the 7v recommended battery.
Well... lol... all I can say is "wheelie-king"... lol It absolutely FLYS on 11.1 volts.
Anyway... not wanting to fry the factory setup, by dinner time I was back at the local hobby shop and came home with a Novak brushless system for it...http://www.teamnovak.com/products/br...tem/index.html
I bought the Novak "#3000 GTB System with Velociti 3.5R motor...
Here is the motor chart... (Velociti 3.5R) www.teamnovak.com/products/brushless/motor_spec_chart.htm
and the ESC info: (GTB Racing / Brushless) www.teamnovak.com/products/esc_spec_chart/esc_spec_chart.htm
This is my first brushless experience... all my planes are just cheap Parkzone/Hobbyzone brushed setups that work on 11.1v. This Novak system says: "For 4-6 [email protected] per cell or 2s Li-po"
The guy at the local hobby shop saw my 3s 11.1v batteries when I brought them in to buy a decent charger....
My question is... Can I still run these hotter batteries in the Novak kit ? or will I burn-up my $229 brushless system ?
I don't know if I should just buy a few 2s Li-po's or if I should return the Novak stuff and look for something 3s compatible.
Your opinions are appreciated !
Thanks !
I finally bought a decent charger... I got tired of the Parkzone junk. lol
I took the fan off... hoping it may let the battery run longer... I'll keep an eye on the temps once I get it going.

RE: Official E-FIRESTORM thread
Wow nice setup.....First thing that setup is not made to run on 3s...you will fry it...second you will need to run that fan for sure and you will want a heatsink on the motor....And this is important you will need to gear that thing way down...Really that set up you put in is for a onroad car...its way too much for a ST offroad truck......Better get a temp gun and check the temps every 5 minutes so you dont de-mag the motor....
let us know how it works....myself i would bring that setup back and get the 3s havoc with the 8.5 motor....you could run the stock gearing and use your 3s battery and run around 50mph...without heat issues.....The havoc setup is $160 and comes out in a week or two....
Anyways take some vid of your storm when you run it with your 3.5.....

RE: Official E-FIRESTORM thread
Well... I took it to the local hobby shop for a little help programming the ESC... we got it running good now.
I only ran it a few laps around the huge parking lot... maybe 5mins worth of run time.
The car is almost undrivable. It will wheelie and flip over backwards at any speed with just a quick blip of the throttle.
I LOVE IT !!!!
I did pick up a Venom 7 volt 5000mah Li-po battery for it... hopefully that will tame it down a little.
Re the fan... I'll get it back on the ESC...

RE: Official E-FIRESTORM thread
I just finished running the heck out of it tonight with the 7.4 / 5000mah Venom Li-po battery...
Motor temp never went over 125 degrees... the heat sink on the esc was up around 200 degrees though... so the fan will be going back on next.
I was really surprised at how well it ran with the lower voltage battery... it really isn't much different than the 11.1 Lipos as far as "overkill" goes. On a fresh 7.4 battery, it will still wheelie and flip over at any speed... It just isn't as obnoxious as the 11.1 battery... which really can't take more than 1/2 throttle before the car wants to go over backwards. At least with the 7.4, I can slowly work my way up to full throttle... at 11.1 volts, full throttle is just out of the question... at any speed. period... makes me wish I had a radar gun... I'd LOVE to know how fast this thing was at 11.1 volts... lol
This is the battery I picked up today... Ithink I may pick up a few more of them.

I suppose I could maybe swap this brushless setup into my Parkzone P51 Mustang and run it 'till the wings fold-up... heck, I'll bet it would fit in my Supercub too.

Sounds cool...Hey if you can keep the temps down and not smoke it,Keep running it.....I would have thought it would have overheated for sure....have you ran it offroad yet? How fast do you think...must be close to 70 mph?

As far as speed goes ? it's anyones guess... is there a way to calculate it? The motor I'm running is a 3.5 turn / 10,500kv motor.
I'm still running the stock gears in it too...
When it whizzes by me, I can see the rear tires ballooning pretty hard. lol
The ESC did get pretty hot earlier today, but the motor was staying cool. Hopefully when I get the fan back on, it will help keep it cooler.
I don't know if I want to risk frying the ESC by running the 11.1 Li-po's in it long term. I'll stick to the 7.4 2s's for reliability.
If I can somehow come up with a radar gun, I'll throw the 11.1Li-po's in it for a top speed run... My curiosity is killing me. I never could get it over 1/2 throttle without flipping over or running out of room... so a REALLY big parking lot will be needed too. lol

After recommendation from Redfisher I ordered and have just recieved 2 x 4000mah Zippy Lipos from Hobby King (Hong Kong) price including postage to the UK was £45, They look very good and looking forward to using them!! Far cheaper then the high price brands available here! Thankyou Redfisher

Thanks red
May wait until my birthday before I switch to lipo - gonna need two packs and a charger, and there doesn't seem to be much choice in the UK, so the price is really high.
Can't wait though

Just put on Dirt Bonz Jr's on the back, love them. They're super soft though, so I'm done with gravel and tarmac for a while. They're holding up really well on grass and soil / dirt, so hopefully I'll not be spending £15 every 3 weeks on tyres now

For speed tests i just borrow my buddys gps out of his truck and tie wrap it to the chassis and it will hold and tell you the top speed...

I've got an extra GPS unit... maybe I'll give it a try.
I'm not so sure about accuracy though.... one of my GPS units showed a max speed of 178mph... in my '03 Chevy pickup truck... lol
I've since upgraded to an in-dash unit... I don't know where I'd be without one now. (probably lost somewhere. lol)
