Hyper 7 Conversion - Most reliable?
 

I'm going to be doing a Hyper 7 conversion. It's been done quite a few times so I think everyone has a pretty good idea of what works with 1/8th scale. I've spent the past two days checking out forums and I think the best setup for me would be:

Neu 1515/1Y
Quark Monster Pro
16v worth of LiPo

There is a electric conversion mount in it already but it's really thin and meant for two motors and one side has been cut off. This will most likely have to be replaced to prevent gear slipping. It also has a roll cage which I want to keep on it to protect the electronics from crashes and maybe add a camera in the future. The chassis weights 6 pounds with no electronics.

Cost is of no concern, with in reason. :018:

My goals for this (in order) are

• Reliability
• Speed - Optimal speed/torque for this drivetrain. Nothing crazy.
• Run time

1. Is a Neu motor necessary to keep from overheating? The drivetrain apears stock but will this have enough torque to twist up shafts?

2. This setup is awesome and probably the ideal for my truck. I imagine that is a custom mount but I heard Mamba max controllers are not a good pair with Neu motors. I don't have the resources to make a custom mount. Where can I find a good one?

3. Are those $450 MGM boat controllers applicable? I imagine they are meant for A high voltage setup with a low kV motor like the 1515/1.5Y which would prevent thermaling. It doesn't seem like anyone makes a good speed controller for 1/8th scale that doesn't have thermal problems with out modification.

I can take pictures of the rolling chassis if that is necessary.

Thanks for your help. Oh, yea I'm new and this is my first post :)

Welcome to the forums. You should check with Mike (RC Monster) about the motor mount.

Since buggies are relatively light, you really don't NEED to go with the 1515/1Y. You could also go with the lighter 1512 2.5D, which is less current hungry allowing you to run a smaller battery pack.

Good combos that would run cool would be the Quark/Neu, Compro/Neu, and Mamba Max/Lehner.

Of the controllers that run with the Neu, the Compro runs cooler, but isn't as smooth as the Quark.

You also don't need a $400+ Compro. The 16018 would be fine.

Whatever setup you go with, try to keep your max rpms under 35,000. IMO, around 30,000 is better. Believe me, you WILL get the performance.

I wouldn't say that I've twisted too many axles, but I have worn the nubs off of the dog bone end of axles. Everything gets driven harder when going with brushless. If you keep it sane, the maintenance isn't much more than it is for a nitro setup.

Thanks for the quick reply

While the Mamba max/Lehner combo sounds good since mm are such nice controllers, The Neu motor appeals to me more.

heres a pic of the chassis so far you can see the motor mount. Do you think this is good enough for the Neu 1512 2.5D / Compro 16018?

The mount looks a little thin IMO. Besides, it looks like the only mount point is on the CD plastic part - not strong enough I'm sure Mike has something that will fit that buggy.

BTW: I can say with certainty that a 1512 will be PLENTY! I have a 1512 2d (2600 kv) on 4s that just screams and has gobs of power. Temps are surprisingly low too. Geared appropriately for ~40mph, everything should be quite cool.

Yeah, that mount looks like a whacked off emaxx mount. You'll definitely want something a bit more rigid. I'd say at least 3/16" thick and 1/4" would be better.

Some have used emaxx motor plates like that... that was my first one too. IMO it will be ok... there will be more flex that with a thicker one... but guys do run big motors on emaxxes all the time. But most of us here like to build things pretty tough... overkill is good type of thing. I would recomend you make a bracket/brace for the rear of the motor... even if it's just a simple piece of L angle bolted to the chassis snug up to the back of the motor.

I just did a Hyper 7 conversion and used a EMaxx mount (from Trinity). It works fine with the rear of the motor supported... however the strain put on the center diff support is bound to cause some problems at some point down the road IMO. So I'd agree with the others in saying use a different mount. Mine is just short term till I can get one from Mike or make one myself. I had emailed him about a mount and his reply was that he would have one available on the site soon. He told me to just keep checking the store.

Thanks It's nice to hear from someone who has experience with the exact part I have. I think this might be it It says Kyosho electric truggy. We'll see what Mike says.

The buggy you pictured is NOT a Hyper 7, nor any kyosho buggy. In fact, it's an Ofna MBX R2. I have the exact same buggy. I couldn't find any motor plates that fit, so I made my own out of a spare 3.5mm chassis.

Oh, damn you're right. I didn't know what it was so I was comparing pics online and the hyper 7 looked pretty close except those plastic sides. That sucks because I read that the Hyper 7 is the toughest truggy/ buggy you can buy :002:

I guess I'll make this a basher then.. I guess that will just save me more money for my on road highway buggy
