Best motor for 1:10 truck on 8 cells?

[Rtsbasic]

Hello, I currently use a 540 6s between all my 1:10 trucks on 6-8 cells, but am looking for a replacement that will hopefully be faster, and safe to run on 10 cells (even if its past the efficency point I'd like to run 10 cells without overrevving, but gobs of power on 8 cells).

The trucks it'll live in is my RC10T2, and RC10GT. Both weigh about 2.5KG (5.5 pounds) when RTR with a 7 cell battery, and run heavy/oversize Masher 2000 tyres. The tyres really rob a lot of power but I love using them just about anywhere.

I was thinking maybe a Feiago 8s, but I don't think its going to give me more power on 8 cells than my 6s somehow, although it would be safe for 10 cells just about. Are there any motors that will push this heavy car faster than my current setup without increasing the amount of cells? I'm using a Mtroniks Genesis Pro controller btw, it handles the 6s fine so should handle hotter motors without a problem.

Thanks!

Either the Feigao 8s or 9s will do the trick. The 9s might be a better choice, and it would stay cooler.

[Rtsbasic]

Thing is, will the 8s or 9s be slower than my 6s on 8 cells? I know the whole system will be more efficent and cooler, but as I only run in 5 min mains when racing, and for bashing am rarely at WOT runtime isn't an issue. The motor is coming off a 5 min run at ~45C so isn't very hot, but if I gear up I loose too much acceleration.

Spending bigger money on a motor isn't too much of a problem, I looked at a Lehner XL and think that might be a good choice, but have bad experiences with Lehner Basic's.

The 8s and 9s should be better than the 6s for the reason you said you didn't like the 6s, you should be able to gear up and be maybe a little faster than your current setup and have room for more if you need it

[Rtsbasic]

I have nothing against the 6s (it works well for me, completely different to what a lot of people have said it performs like). It doesn't overheat and wheelies my trucks up to a good speed. But I want more power, and ability to run a couple more cells. I'm not 100% sure a higher wind motor of the same sort will give more power. The 6s is torquey enough to lift the front wheels of any car at 20mph+ when I'm running on a high traction surface, and it'll keep them up to its doing around 35-40mph, with it topping out about 40mph.

Are there any other makes of motor that would give me more power for the same cell count? I'll keep the 8s under consideration, but I don't think it has the power I'm looking for (maybe I can't get the power I'm looking for on 8 cells? in a fairly heavy 1:10 car?). I can't charge more than 8 cells on my Novak Millenium so I'm somewhat limited by that.

Thanks for your input so far though guys, I appreciate it :)

The more cells the more power. That is something to keep in mind.

You may want to try the 1920/7 brushless motors made by Lehner. It is a highend motor and can run super efficient and super fast on 8.4 or 9.6 volts. You can use it as either a motor of torque or a motor of speed according to the configuration of the motor's wiring. Mike can get them for you if want them, but the problem with these things is the price. The 1920 series would cost you atleast 190 dollars in the best case senario. In size it is very similar to the 6s, but a little shorter. You can visit www.lehner-motoren.de for more info and pics of this varacious beast.

You may as well go lipo if your goint to spend that kind of money. All your motors should come to life. The lehner basic 4200 is a good motor for 8-10 cells or 3s lipo.

Rtsbasic, i really like the T2 they're really cool,i was thinking of trying to find a good one,are they easy to get parts for?

Have you considered using GP2200s to keep the weight down a bit,they're 44g each and 34 mm long,just a thought anyways.

[Rtsbasic]

I like the look of the 1920, its not totally beyond my budget. Mike, could you get hold of one of these? If so how much do you think it'd cost?

The Basic 4200 doesn't put out the power I want, I had a 5300 and that wasn't enough to push my truck well, my 6s does a much better job.

Gustav, the T2's a brilliant truck. I have fitted every RPM part to mine, ti turnbuckles, cvds etc and its really nice. I've been jumping it 6-7ft in the air onto concrete all afternoon at over 35mph and am well impressed. For some reason its a lot easier to land jumps with than my T3 or RC10GT ever are. Eventually I ripped some teeth off the spur (switching to 32p very very soon).

For parts availability isn't as good as newer trucks, but its not bad, 80% of parts are shared with the RC10GT, so they're really easy to get. The other 20% pop up on ebay from time to time, but I believe you can still order the parts from AE through any LHS for it. Worst case secarnio Tower Hobbies in the US stock most parts for it.

GP2200's I've thought long and hard about, but I already have 3 matched 8 cell GP3300 packs that I'm not in a hurry to replace, plus the 2200's are expensive for what they are. Wouldn't mind getting 18 or so of these in a T2 and watching it rip. Lipo's I'm thinking of as well, I'm trying to find a new charger for around £50 or so I can do lipo's with, currently looking at the Pro-Peak Mercuery as it does 1-4 lipo and 1-25 nimh all off 12v.

Sorry for the long post :)

Best part is it only cost me £21 with quite a few spares as well (and a complete oval kit).

I have a suggestion. Not sure what kind of room you have on truck for motor. Will a 7L feigao motor work. It will have more torque and more rpm the the 8L. Not sure how will this will work for you. Just a suggestion. Something to think about. I not sure what you are looking for.

[RC-Monster Mike]

The 1920 will be around $210 and yes, I can get them.
I used to have a T2 myself. I am sorry I ever sold it, actually. I modified the rear turnbuckles to accept a 1/8 link and installed an alloy idler gear and it was as bulletproof as anything I've ever owned. I also maneged about 65 mph with 8 cells on an 8s motor.

[captain harlock]

Coolhandcountry, the 7L is much heavier than the 1920/7 and the guy wants something to go fasssst using 8 cells. The 1920/7 is the ideal setup and I think the 4200 and the 5300 are good as well, unless there is something wrong with the batteries.

[Rtsbasic]

A Feiago L or XL motor isn't really suitable for my cars unfortunately.

I can believe the T2's capable of 65mph on 8 cells, I've achived the same speeds on 8 cells with my T3 (which is lighter), using normal wheels. Problem is the the oversize tyres I normally run drain the power, so that potential 65mph becomes 45mph.

$210 is good..I'll have to see what I can do at the end of the month. How much power do you think a 7 wind one of these will spit out compared to my Feiago 540 6s, both on 8 cells? I know the Lehner will be more efficent as well as it won't be revving to over 50k RPM like my 6s.

I dunno why my 5300 couldn't push my trucks as well as a 6s, it moved like "s**t off a shovel" in my TC3, and in my B3, just not in the trucks.

Thanks for your help and advice guys, its appreciated.

I will keep that in mind. Just trying to widen the view. Some time you get stuck on something when you supposed to be on something else. If you know what I mean. Good luck on project. keep us up to date.
