Default What 1/8 conversion last the longest

I have been looking into converting my RC8 over to brushless. I have been given a list of things to buy, but before I drop 5 or 600 more dollarswhich ecs/motor combo seems to last. I have read were some people are on their 2nd or 3rd combo. I know some of these combos have gone thru several "version". I am sure some of these are under warranty but who wants to go weeks at a time with nothing. So whos combo is built to run?

This is what you need for the "guts" of the conversion: http://www3.towerhobbies.com/cgi-bin...&I=LXWMB1&P=ML

And this to power it:http://www3.towerhobbies.com/cgi-bin...?&I=LXVJN3&P=7

Keep in mind you can take another $25 off using discount codes, you should be able to get this done for about $350, plus the cost of some lipo's. Ultraline hobbies has some Yeah racing packs now ROAR approved that have really good prices.

I'm going to convert my SC8 using these items.

Last year I started off the year with a Tekno converted Revo using the Novak HV 6.5 system along with a 3 cell lipo and had the rotor come loose from the magnet. I replaced the rotor and then after a couple of months I got a good deal on a brand new Tekno Converted 8ight T and have not experienced a problem with the Novak system since. I am thinking about trying out the new Tekin RX8 when it comes out, which according to an email I got from Jim Campbell is suppose to be in a few weeks with their motors a few weeks after the RX8 speed control. I am considering the 1700 K/V system with a 6 cell lipo to keep the heat of the motor down a little more than with the Novak system. The Novak got a little warm in my opinion but I think that is mostly because using the Tekin setup with the new chassis and motor heatsynk/mount the truggy is much heavier than what it would be using the direct drive technique. A system using higher voltage and lower K/V motor uses less amperage than a system running lower voltage and a higher K/V motor, so the heat should be considerably less. I am also considering keeping the Novak system and buying a Losi L8ight Model, converting it to electric and then using my two 3 cell Lipos in that.

Sorry for the long post, I guess what I am saying is the Novak system is good, but I would also look at the Tekin brushless systems. I have both the RS pro and two of the Mini Rage systems and love all 3 of them.

go here:

www.holmeshobbies.com

Use code "ESC" after selecting the Mamba Monster combo you want. that should bring the shipped price of the Mamba Monster combo to $250.

As for the conversion to use for an RC8, I would give the RCM conversion a serious look as it moves the battery pack weight over to be more centered. I have this for the RC8T, and its great. I also have the RCPD RC8 conversion which is great if you want to use long packs.

Main thing to keep in mind with dual lipo setup is you will want a charger that charges both packs together as one and balances them too, as one. the Hyperion duo does this, and no manufacturer currently will make a balancing Y connector so you could use a regular lipo charger.

good luck.

There is another thread, albeit long, about 1/8th conversions. I will distill it for you. Most people have tried and trued the MMM v3 and a Neu motor on a 4S LiPo. Most people choose the Neu 2.5D/F motor. The new Mamba Monster combos are seemingly well received and are based off the Neu design. For a buggy CC recommends the 2650Kv. This is a fairly hot motor so you will want to make sure you have quality cells to supply the juice.

I hope this helps!

One other thing I forgot to mention is that the Tekin speed controllers can have their software updated at any time you are at your computer with the Tekin Hot Wire. It just plugs into your USB port on the comptuer then you plug your speed control in start the program and it asks you if you would like it to go online and search for updates if you click yes it will go online and get any updates for your speedo.

If you do not have your conversion ordered you can also check out Impakt RC they have the RCM, Novak and Tekno conversion for the RC8

if you are using the AE conversion kit, it says you need a new e body ASCC8923.

Is this true, or can you use the original body with AE's conversion?

I'm also undecided to which conversion kit to use.

Also, is there any 4s lipos bigger then 5000. Might go 2x IP6000 30c packs to last 20 minutes

edit....anyone use these http://www.hobbycity.com/hobbycity/s...idProduct=6325?

RC Lipos has a 6000mah 4S 25C PolyRC pack for about $185 right now shipped anywhere in the world. I run two of these packs, and they are excellent. These however would NOT fit the AE conversion, but will fit the RCM conversion, as I use them in mine.

Another option is the maxamps 6500 30C packs, I know a guy using these and they work well too, and are more 1/10 scale sized.

The RCM conversion and Tekno conversions probably do the best for moving the battery pack weight over as much as possible since they use a different chassis. For stock chassis, the AE conversion does a good job too. I run the RCPD conversion on my RC8, and though it looks from pics I have seen of the AE conversion to not get the battery over as much, it still performs quite well and I am happy with it, even when using my 4S 6000mah packs.

I run the stock body on my RC8E, it fits with my setup and the battery I have, in my signature. I run the castle Monster max and 2650 motor, and honestly its too fast race on a track, would have to change the gearing if I wanted to race it, But for going 55mph up and down the street and freaking out the neighbors, its fun as hell.

Well suppose I can rule out the AE conversions, as they are only good for 2x 2s packs, someone who has 1/10 lipos.

what run times are you getting from the 6000?

On the track I run, its a battery sucker, I get about 18 minutes. I would say though if traction is good on your track, and its not huge, you should get easily 20 minutes or more.
