Homemade 1/4 scale Replica of Baja.
In the making process of the replica of hpi baja but in 1/4 scale..Some of the components part have been consolidated..waiting for the final..measurement.
hopefully it can be turn out to be the replica of hpi baja but in 1/4 scale.For the time being i will use some part of the baja not most of it when the final drawing is out,den it will be replace by raw material...I will be using 49cc engine hopefully powerful enuff..
the size in length and width have not been determine yet but i have came up with a blueprint of the rear drive.Jus a simple rear drive without any complication and taking to much space.Im trying to cut down the weight to less than 50kg possible.why im making this...juz pop out of my mind...inspired by sumone..it may takes sum time for the project to finish so sit back n relax for new updates.getting part drawing etc needs time for me unless i have a workshop on my own,here and there i have to run to send for welding cutting etc...
Heres sumting of my blueprint with out the upper n lower arm and wheels.

RE: Homemade 1/4 scale Replica of Baja.
Cool, I'm interested in seeing this project go to fruition. A larger Baja is good for everyone! I used an identical driveline setup for my 4WD car with the same size engine and it worked out well - the scale was smaller, however. I'm staying tuned...

RE: Homemade 1/4 scale Replica of Baja.
Not to hijack but are you thinking something along these lines maybe, This is my latest scratch build using a 46cc engine. I don't know what kind of wheels/tires you plan on using but if you go too big on scale and want to use hpi baja wheels they will start to look kind of funny. Also witha 1/4 scale you should be able to keep it under 25 kg. Just don't go overkill on your frame. This car is about 16-20kg with plastic wheels. add another 3-4 kg for those billet wheels. I went with a TIG welded tube chassis with TIG welded tubular suspension arms as well. The transaxle is my own custom design and home-made prototype. Some of the pictures are not so good but hopefully this gives you some ideas.

Brice's creations are always so shiny and nice, lol...
wan6176: Here's two pics of when I was first putting may car together (it had two layers so one pic is from above and the other from below). It's come a ways since then but the general idea is there - I'll try and post a vid to give you an idea of what to expect. Cheers!

RE: Homemade 1/4 scale Replica of Baja.
thks fabe looking forward neatly place all the item nice tyre good ciurculation of wiring....i like the hub holding the sprocket...i have the bearing holder now waiting to make the shaft the sprocket hub n brake hub once its done i will juz put the item together take a pic of it...once the rear drive is ready den i can proceed with the engine installation n position,now im wondering whether to use steel plate width 2.5cm as a body frame or a tubular steel tube...im stuck at welding as i need to go here n there...i will tink abt it soon. using tube steel might bring down the weight less than a plate steel.

RE: Homemade 1/4 scale Replica of Baja.
Thanks for the comments, guys. Sam, I will post a vid or two soon - I'm just waiting to film something new!
wan6176, you mentioned using steel plate 2.5 cm wide, but what thickness? Are you planning on something similar to Brice's or a different look?

but where is the adjustability as you see on other largescale. If the numbers are wrong then you have to start over.[:@]

fabe the thickness is 2-3 mm that might coz alot of weight if i were to use steel plate but easy to bend n drill hole for engine mounting n other application.

RE: Homemade 1/4 scale Replica of Baja.
Looks like you should have all the stopping power you need. I get the impression that a tubular frame would look more realistic and would weigh less. If you're interested in seeing what that kind of engine can do, I started a thread over here. Did you say you were going 2WD or 4WD, btw?
