Default MAMBA MAX 7700KV VS NOVAK GTB 3.5R

Hi guys, I have a Xray T1 FK04. I was about to buy a New Novak 3.5R bl setup for AU$450 shipped. I then found a New Mamba Max 7700 setup for AU$250 shipped. Straight away I thought the Mamba for sure, considering nearly half price.

This is what I want to know:
Which one is better overall?

The 3.5R does 10500 for every volt. Times this by 7.2 you get 75600 RPM. Does anyone know what the Mamba does per volt? Cheers

I will be running a 48P 72T spur with a 48P 25T pinion. If that helps.

with mamba they tell you how fast it is in the name.....5900=5,900rpm/volt
7700=7,700rpm/volt......i think it it around 54 thousand rpm...which is 23 or thousand less rpm....which equals 2 about a 18t motor.....and the power diff is incredible......almost a horsepowers worth of power at full noise from the 3.5!

i reckon get a GTB or a LRP TC spec or a Sphere....so there is no more upgrading...if u want 2 run a 3.5 and u get the Mamba....ESC wont handle the power....so i reckon get 1 of the 3 ESC's listed above...so there is no better motor that u cant run!

I would just go with what you can afford or willing to spend, I had both and if you plan on running 7.2v my opinion is go with the novak 3.5 if you plan on running more than 7.2 volts then go with the mamba. Remember the max rpm that you are looking at is unloaded rpm, when you run loaded rpms the rpm readings change, it all depends on your car if it's heavy or light the performance changes and with gearing too, alway's keep that in mind. Good Luck...

not sure about the Novak since I never had, but I can say the Mamba 7700 in a Mini Cooper is something you can say to others, "catch me if you can."

3.5T motor with this gearing (FDR 4.896) on 6 cells? I can only wish you good luck.

A 7700 would pull that gear...but a properly geared 3.5 would kick its ass.

I had a 7700 in my TC and even geared down around 5.0:1, it would pull without getting hot at all...but there was another guy with a 4.5 that would pull me on the straight.

Just depends on how much money you are willing to spend. Go with the one that you think will make you the happiest. Everyone will have an opinion but only you are going to be running it so you are the only one that has to be happy with your decesion.

Just remember for your money what would you like: a speedy that will take most brushless and brushed motors and is programmable to how you would like to run and warranty on your purchase , fast turn around for warranty. if you buy out of the states it will take quite awhile if you have a warranty clam.
Harris rc has the mamba max range and is very good to deal with.
i do believe that the 4600 mamba max is a great package with lipos just stack them up and go. i have seen one running on 14.8v (2 packs lipos) and and wicked smoke every where of the tyres.

Hi guys, I would just like to thank you all on your opinions. I have decided to go for a 3.5 bl setup. However I saw that a few people have reccomended the LRP TC with the 3.5 bl setup. I know that the LRP Vector x11 3.5 bl motor does 70,560 RPM at 7.2 volts which is just over 5,000 rpm less than the 3.5. But I still think it will put out more power than the 7700 on 7.2 volts.

So my conclusion is, I will be buying a LRP TC ESC and a LRP X11 3.5 bl setup from harris R/C here in Australia so if I only ever run it on 6 cells I should have no problems on warranty. Cheers guys, you all have helped me in making a decision.

Hi guys, I was just going to ask one more question:

I am currently running a 48P 72T Spur and a 48P 25T Pinion on my T1 with 60mm tyres which gives me a rollout of about 30mm

Would it be safe to run that rollout on either the Novak 3.5 or the LRP 3.5?

If not what would be the maximum rollout I should be going to on a 3.5 to still claim warranty? Would it be about 28mm rollout. Or is the 25mm rollout the most I can claim warranty on.

Cheers, I hope I am making sense here

The KV rating doesn't really mean power. The main thing you want to look at is the watts of a motor. I know from personal experience that the LRP is a little faster than the Novak and a lot faster than the Mamba.

I am most likely going with the LRP 3.5. However I just wanted to know what would be the maximum rollout it could handle still being able to claim warranty?

I am not talking about a super high rollout of 40mm or something im talking in the low 30's and high 20's.

Has anyone run the LRP 3.5 on low 30's rollout?

Cheers

I think about a 20 rollout would be pretty close. Most use Final Drive Ratio (FDR) to work out their gearing. With the Novak you gear between a 10.2 to an 11.2 FDR (start around a 10.8). An 85t spur and a 14t pinion will give you a 10.7 which is pretty close. I don't know what the 6 cell gearing is for the LRP's.

If I were to use a 85T Spur and a 25T Pinion. Is that overgearing for a LRP 3.5??? Would I still be able to claim warranty
