don't know about the 1.5R Caster. The origional Fusion i got a chance to drive and I did like it. It was between that and the Hyper 9E when I upgraded, but I like the single battery pack design and also like the layout better with moving the center diff back so you can move the electronics tight to the centerline of the vehicle. The Casters a good vehicle no doubt.

From what I could tell as I owned a converted RC8 versus the Hyper 9E, the Hyper 9E changed directions quicker than the RC8 and felt more sure footed once dialed in. it also felt more nimble using the same electronics than my RC8 did. keep in mine, this was using a heavy 6000mah 4S battery pack.

I loved my RC8, and this was just better.

Agreed, the rc8e was my 1st 1/8 electric when I got the Hyper 9 it took a little getting used too but once I did there was no going back so I sold my rc8e. Driving the Hyper 9e more agressively is a great way to describe the difference.

Well said Cain.

I make a lot of carbon fiber parts for the Hyper 9e, so let me know if you guys want something done.

The rx8 radio tray worked out really nice. It was a convenient way to mount the speed control directly to the chassis and still maintain the buggy's structurel integrity. Nice job snrscion.

you back with us cain,what you driving now ,as you sold your hyper 9e a few weeks ago,right.

Thanks, appreciated the props.

I am really after what pinion sizes I should be looking at to start off with, not what I need to do to make things fit.

Not interested just yet in trying different size motors until I get my head around this lot first. The track I will be running the EP on will be Astroturf with very little change to the layout or surface.

Well, most people seem to think it's best to gear for around a 35-40mph top speed, as this is a good compromise of low end acceleration and top speed for straights, and is very competitive with nitros. Let's be honest, an 8ish pound buggy flying along much faster than that is a pretty scary proposition anyway. Obviously you can tweak from here depending on the layout of your particular track.

With that in mind, assuming the 2200kv motor, 4S and most tire choices, you probably want a 14 or 15T pinion. This is where the grinding may come into play, as I think 16T is the smallest pinion that still fits without the motor can rubbing the diff outdrive using Castle or Tekin sized motors.

Play around with the gearing calculator here:

The front/rear diff ratio you want is 3.91, more or less, and the Hyper 9E has a 44T spur. Unfortunately you really can't go any bigger than that (if Ofna even has one available) because it will hit the chassis plate, which means raising the diff, which is basically impossible (or at least highly impractical) given the way the buggy is made.

The big reason to go with the lower KV motors with the 9E is you just get a lot more options for gearing, batteries, etc.

A buudy is looking at getting a hyper 9E, and was curious about the chassis mud guards. What are you guys using, If anything?

I think some people are using the TEKNO Rc ones. I personally would go with the Hyper 8.5 mud guards if I still had my 9e just to fill it out more!

Thanks for that Ezrem. The 9e actually uses a 40t spur, so I'm assuming I'll need to come down in pinion size from what you mentioned.

Just worried about cooking the motor on it's first run out. I guess that can be avoided by programming the esc correctly.

The Tekno mud guards work great on my Hyper 9e.

Whoops. I was going from memory on the spur. You'll almost definitely need to drop another tooth or two then.

You know, I think Cain was running a MMM 2200 combo on his Hyper 9e before he went Tekin/before he sold everything. He might be able to weigh in on this as well.

Also, +1 on the Tekno mud guards. They fit almost perfectly. All you have to do is notch them a bit at one end to make them wrap around the chassis, and drill some countersunk screw holes. It's like a 20 minute job.

Do you have a couple more shots of that rear brace you worked up with the turnbuckle and ball ends? Looks...interesting, to say the least.
