Hyper 7 on 5S
 

Shot some vid today, finally had some dry weather.

It's got some torque. :mdr:

Nice speeds with that thing... love the big red brick... :lol:

Very nice (Borat tone) almost makes me want to keep the hyper7 I'm offing, but not really, mine is still n#tro and I've just had enough of it. Going to save the $$$ and do a direct drive revo some day. Sweet hyper Sleebus!!!

That buggy rips!! :intello: Looks like a handful to drive too. :lol: Enjoy it. :smile:

Actually it drives really nice. It is really hard on the front tires, and spur gears. I'm running a the plastic 46T Kyosho spur, and I've removed several teeth from it. I'm going to switch back to the hardened steel one. I think it's happening from the shock of the wheels coming off the ground, hitting full revs and then slamming back on to the pavement. The shock load is probably what's shearing teeth. My poor road rage tires are bald down the center now, haha!

Nice ride, super fast off the start it's hard to get a buggy to do wheelie off the start.

I need to shoot another vid, because if you thought it launched hard before, you should check it out now!

What was happening on launch is that it would pick up the front wheels, the diff would spin the front tires up to full RPM, unloading the back, which allowed the front to drop and hit the pavement at full RPM...which transmitted a ton of shock load to the spur. The end result was that it sheared 2 teeth off the spur and folded the 3rd over. The spur I was running was the 46T Kyosho plastic spur.

So, it was time to put the hardened steel spur back on. I have a hardened pinion, so that wasn't a problem. Also, the Kyosho never sealed up quite right, and leaked, so I wasn't able to keep any fluid in the center diff.

So, I pulled the Kyosho off, filled the diff with 10K fluid and put the steel one back on. Even tho I was able to use fluid in the diff now, I was kinda bummed because I liked the quiet of the plastic spur, and I had heard the steel ones were noisy.

Guess what? Not noisy at all. I was expecting it to sound like a buzz saw, but it was just as quiet as my plastic gear. Maybe an extra zzzzing every now and then, but man, I should have made that change LONG ago.

Going to the 10K fluid helped a lot too. The wheelies are not as high now (which I kinda thought would be the opposite) and MY GOD does it accelerate out of the hole. It appears to reach about 80% - 90% of top speed in about 4 - 5 feet. It's really amazing to watch it launch. There's just enough rear bias now that I can drive the rear end around with throttle on concrete. It feels really good. Now I'm even MORE anxious to get this thing on the track, or at least off-road a bit.

Can't wait to see the new vid. What did you use for the motor mount? Did you make one yourself? or is it from RCM?

Originally I made my own mount, which put the motor about right where the nitro motor used to be. That made a real bad setup for battery mounting. I bought the RCM one that puts the motor on the other side, which leaves lots of room for that big red brick I've got.

The mount works great! After what I went through to make my mount, the $40 was well spent!

Very nice sleeb. It looks like it handles really nice. I bet it's a "smooth" ride to run eh? It looks like it runs like butter man.
