Electric Losi 8 buggy weight? - 11.10.2007, 05:24 PM

I am in the process of a Losi 8 buggy E conversion and I wanted to know what the norm would be for the weight of this setup?

I put everything in the chassis and weighed it and it looks like 120 ounces is the all up weight (including my Eagle Tree). The setup is;

Neu 1515
12S Flight Power 2170 cells
Castle Creations HV 110 ESC
Nomadio reciever (React transmitter)
VHV-BEC
Hand machined motor mount
MIG welded piano wire roll cage under the body (this would add a few more ounces if I go with it).

Does that weight sound correct? If so, this this should absolutely rip the tires off! This same power system is running in my top speed TC4 (110+ mph car) and draws 3500 watts. In this application, I would think 2500 watts is what I will be seeing reliably.

Any thoughts?

Matt

sounds about right... that's what mine is (actually I think mine was less with a 5000mah pack... like 7.2lbs)

A clean nitro 8ight is about 7.25 lbs without fuel IIRC

Cool, thanks guys.

I figured as much. But, this is my first 1/8th conversion. So, I wanted to find out what I could about it before I proceed.

I could go down to 8S and save alot of weight. Plus the power would be more reasonable. But, heck, I see no reason not to go all the way.

Yup, its an RTR. Got it off Fee-Bay this week. I already had the power system and the Nomadio sitting on my bench new in the box (stuff I bought for another top speed car I never built). The stuff was screaming at me just sitting there. So, I picked up the 8 to setup.

I own a bunch of bench top milling machines (Taig 4 axis CNC, manual 4 axis, and lathe). I can make anything. I miss my old MP6. So, I figured I would build an 1/8.

Here is a truck I am in the process of building too.

I would add 3-4 ounces for the brake servo, another for the eagle tree... so yeah it will be more than mine.

I would guess about 7 3/4lb plus the roll cage.

Gotcha.

Yes, I will be running a brake servo. The HV 110 has a terrible brake (if you can even call it that). It is, after all, an aircraft ESC.

Actually, I already added weight. The scale told me 110 ounces without the brake servo or Eagle Tree (I will just run my Micrologger). But, I am adding a few ounced into my calculations for wiring I haven't considered and misc. hardware I haven't considered.

Here are a couple.

They are mostly of the motor area because I took them to highlight the new layout. It used to run a huge AXI outrunner in the center of the chassis. Now it runs a Neu 1512 "Under the hood".

It is not a crawler. It is a bashing truck. It snaps wheelies on demand. ;)

This is quite possibly the coolest looking rc vehicle I have ever seen!!! A work of art, great job mod man!!

Any chance that you would make me one, or possibly sell it to me? I love collecting the strange and wonderful rc creations people come up with. Figured that there is no harm in asking?!

Hmm, this thing is worth a fortune. I built it over quite a span of time. But, I bet I have over two grand in the thing. Heck, I just bought two 403 ounce torque steering servos for it. That alone cost me $250! The tranny is a 100% hand made gear case driving a belt drive transfer case down to cut, extended and rewelded CVDs to the axle housings. The suspension is all custom made and completely unique. The sway bars are ball bearing pivoted carbon fiber units made on my CNC. The roll cage is hand made mig welded piano wire (you could stand on the thing).

If you are serious, I am willing to discuss it. But, again, this thing is worth an enormouse amount of money. Heck, I haven't even finished this latest upgrade yet (the steering servos, 4WS, and transfer case).

Thanks for the kudos, though.

Actually, this thing is nothing. Here's a pic of a CF heli I completely scratch built.

I just enjoy the challenge of designing something and seeing it come to fruition.

I hope the Losi turns out this nice.
