I'm wondering how that Bolido stacks up against the Neu 2215 then. I would rather stick to Neu since its in the US and makes it easy for service.

That's what I tell everyone now, to stick with Neu because of their location and great record on repair time. If Lehner and Plettenberg can come up with a solution to open an office in the US, make the prices more attractive, then we can add more option for 5th scale. I would go with a Neu.

I figured the Neu being rated 10Kw's is more then enough to get that car moving some pretty serious speeds. I don't see why that car wouldn't be able to get 100mph with a 2215 and 12S at least.

Lutach the only that has me concerned is the gearing. Are those mod 1 gears??? Also it looks like it uses several gears for torque multiplication. I don't think its necessary though and probably just go direct to spur.

It should go much faster. Let me get the car here and do some changes and we will see.

Maybe that's for the gas engine. The Neu 2215 will be able to provide plenty of torque to ditch all those gears. I have designed a mounting system for motors, that is very unique and I will utilize it on the 5th scale as well. The only thing that might give up will be the drive line. Just remember that the gas engine will have a peak RPM of around 12-13000rpm and the Neu will go to 30000rpm. The gas only puts out around 4hp and the Neu will be able to put out over 5000 watts or 6.7hp and torque that the 23cc gas engine will never produce. I can see a 5th scale geared properly go around 120-150mph.

Well I'm shooting to turn the 2215 around 55-60K rpms. So I will go SHV if needed. Just have to figure where to put all the batteries.

The Neu 22s are only rated for 30K. I haven't spoken with Steve yet about it, but I don't think 55-60K will be possible with it. The Bolido with 10S will spin at 30340 unloaded and I think that's where the big 4+ pole motors should stay. It might have something to do with the large magnets and the G forces it will make at those high RPM levels. Man, if the 2215 can go to 55-60K safely, you can shoot for 200mph :lol:.

Hmm on the Neu site its says 60K is max......wonder which it is.

Look at the top of the page in the link......it says 60K

It's a Typo. http://www.flydma.com/catalog/index.php?cPath=1_7_8 also here http://www.fastelectrics.com/neuspecs.htm bottem of the page.

Hmm 30K max with 20-25% margin of safety means around 37K max or so. So I guess I will try to achieve 40K then...hehe.

Also according to Flymda, the one motor I was looking at is rated at 172 amps max, and with a 12S input voltage of around 44.4V's that is around 7640 watts!!!.....geezzz. That thing ought to haul some a$$ with the right gearing. Definitely will need the 250 amp SHV 20S controller for it. Guess I need to wait till CC releases it in July.

There are a few controllers out now that will handle that. The Schulze 40.160, Spin200 and Spin300. The Schulze 40.300 will be just too big and I think finding a place for it to fit will be difficult. With 20S by the way, you won't need all those AMPs though. The SHV 110 will put out 7000 or so watts. If Castle can indeed modify them for 160A or so you should be fine. The AMP draw will also depend on the gearing you'll go for. Who knows, you might reach over 100mph with only 4000-5000 watts.

Hmm hard to tell. I am probably close now to 4000 watts with my MMT and am no where near 100mph. Of course drag is alot more though since the truck is much higher off the ground.

I'm using BrianG's speed calculator and the minimun speed I'm coming up with is 60+ mph. The only way to find out is to actually do one :lol:.
