Custom Micro F1
 

Did bother making a tread for this until I had some progress worth showing. Here is my micro SCT that I stretched and made into a F1.

Stil plenty to do with it But it is taking shape. Runngin brushless with custom servo mount, 2 piece chassis, motor mount and mounting plates. Have a small 350mah 2s for it as well. Its currently in RWD, If I am unable to keep the rear end in line then I might have to switch to awd.

AW, how cute :rofl:

Thanks, I guess haha. Its just a little project for the basement.

Well, here are some more progress pictures....

You can get the basic idea of what it is going to look like. Still have A lot of work ahead of me. Plus once the shell is complete I need to sand, align, glue, putty, epoxy then paint it....

Got quite a bit done. But still TONS to do..

Still need to de- bulk it, and finish all the other bits of the body. As well as start the rear end, and mount the wings.

looking pretty good! Will be fun cruising around your basement.

Looks like a fun project. Something to tinker with.

Thanks, Got some more body work done, Really slow and tidious process.. http://i157.photobucket.com/albums/t...ps09e8f412.jpg

Sorry It has been slow, takes a long time to make a little progress. The rear wing I'm cery happy with, not so much the front splitter. Having some ideas of what to do with the open cockpit and the side air dams. The black was just to get some color other then the blue/white combo. Helps to see what needs sanding and filling. Should be ready to get some better coats and some epoxy resin to harden it up.

Let me know what you guys think. Body is glossy because of the resin. Will get sprayed once its all hardened and Im happy with the results. Just need to figure out why im not getting equal left-right steering throw... And make some body mounts.

So I know it has been a while since I've posted, and truth be told I had gotten out of RC. But I am not entirely sure one can EVER really get out of the hobby. Things still stick around and lay in boxes hidden from sight. So a few weeks ago I picked up a 3D printer. Familiar with 3D modeling and 3D printing it got me rummaging through old boxes of what lay left of my rc collection. Low and behold I found my 1/24th scale losi trophy truck, brushless setup and servo. No 2.4ghz receiver or transmitter, or lipo for that matter.

Short trip on amazon and Ive got a Flysky Fs-gtC and a venom 30c 450mah 2s pack on route. It's still a work in progress, as this is fairly small and measurements are tricky and need to be precise, as well as scaled to account for Filament shrinkage during printing.

I am aiming for a rwd scale drift car, no more F1 unfortunately.

Here is a slight teaser of what I have so far and what is coming, with specs on what I have changed over stock.

Chassis:
Lengthen and widened
Solid motor mount with under chassis fine adjustment
Front mounted servo, lipo and receiver
Rear mounted motor and esc
Redesigned front upper A-arms for 1,2,3 Deg camber adjustments
Redesigned Steering rods for Toe in/out Adjustment
Redesigned Shock Tower for inboard shocks
Upper Chassis Brace for regidity
Custom Rims for Offset
Custom Knuckles
Custom Servo Saver

The complete chassis was designed by myself, however the widebody BRZ shell was taken from a 3D warehouse. Although it might be less work for me to create my own. However, that is the look I am going for.

Sorry for the lack of updates prior, but do stay tuned!

Getting some more progress done, Radio has come in, and electronics are all working, which is a nice thing to come back to after a few years out of the hobby. Here is what I have done so far..

Still working on front steering mechanism and tweeking solids to get the most steering angle.

Also started on some larger rims, designing to look similar to Volk 5 spoke deep dish to suit the Brz body.*
Most notably upper chassis brace, receiver/antenna mount, esc and battery tray have all been completed.
Although it looks high, everything will sit under the shock towers.

Well got it all printed out and put together. Will clean everything up once the bonding agent cures the velco.

Well a little bit of an update here.

GOING AWD!

Yes, Im accepting the fact that for basement enjoyment and competitiveness against a 1/18th AE Apex I will have to convert to awd.

Currently configured, I cant even get to half throttle without the back end stepping out, and unfortunately its stopping me from being competitive.

Secondly for switching, is braking. Rwd is fun and all, but as we know electric motors act as a drag brake when throttle is released, letting off the throttle steps the back end out, and the car doesnt stop quick enough for me with only rwd.

So I have a few options here on how to convert it back to awd while still maintaining the stretched chassis.
1) order another drive shaft, cut and splice them
2) cut current shaft, add a section, then mate them again
3) fabricate a new male end of the shaft and attach it to current shaft.

Ive so far gone with the 3rd option, going to run it and see how it goes, if it can handle the power and is durable, I will run it as is.

Because of the awd I will need to slightly tweak the chassis.

Seems I have yet to update this. It's all running now with a 3d printed body. Will get some photos up later on today. Runs very nicely. The Awd vastly improved corner entry and exit speeds, as well as acceleration in the straights.

Been a while since I've updated this thread, made some progress on the chassis. Obviously the biggest change was going to horizontally mounted shocks.

Ended up breaking the motor, was cogging very badly and upon inspection one of the leads was broken off the motor windings, and could not get it to work correctly.

So took the opportunity to order an esc as well so now I can have reverse, which will be a nice feature.

Man its a ghost town around here..

Made some progress on the body. Fixed the body posts so now that the body sits nicely I decided to do some body work on it, make it look more scale. Not quite finished yet, I did the rear, side, and front widebody pieces separately so I could piece them together and made changes.

Got everything figured out for the most part have to do a little more work on the front quarter to close up some of the fender gap around the front and rear. But overall super happy with how it has come so far, not bad for eyeballing measurements and body curves.

Also added a custom front and rear license plate, i've used 2FAST4U as a custom licence plate in every racing game thats let you change it, so I thought I'd carry it forward here.

Added mirrors, which are screwed into the body (inside out).

Added a front spliter as well as a rear diffuser, rear diffuser is glued in place with shoe goo, the front is not yet attached. I think im going to trim a bit off the front of the body, Its fairly low sitting and would like a few more mm's of ground clearance.

Anyway here are the pictures!

Enjoy, and feel free to comment, as always.

Well I finally got my esc and motor in, good job HK, only took 1.5 months lol.

The esc is A LOT bigger than I expected. I forgot how big stuff is I guess after working with micro scale for so long.

Probably going to have to re design the chassis a bit so I can get everything as low and center as possible.

As of right now everything is on the upper chassis brace just for testing. It all works, and the esc programmed up no problem. Happy with everything as of right now.

Maybe ill get to it this weekend, schools super busy so Im not sure I can afford the time to do other things.



We will see.

So Im trying this new approach, Design a million times, print once ahah, to avoid the 8 prototype chassis, 2 sets of rims multiple top braces ordeal that I had previously.

Decided to make my own a-arms for two reasons:

1. adjustable camber (stance nation obv)..
2. Ball diff is wider than stock diff by ~3 mm's so adjustable length arms will keep my track width the same, but allow for the bigger diff.

Still not 100% sure on the ball diff design. Its very common that the belt sits on left or right side of the diff housing, to allow for the center pulley to accommodate both belts ie, rear belt on left, front belt on right.

So I will most likely be changing that, I also think I'm going to need a tightening screw in my diff, Im skeptical about the pressure being enough.

Anyway here is what I have so far..

https://cimg3.ibsrv.net/gimg/www.rct...5567d2f6a7.png

Alrighty, so here is what I have done so far.

Ball Diff is complete. Lets hope it stands up to some power.
A LOT of ingenuity on my end had to go into designing it so that it works the way it should as well as dealing with working on such a small scale.

It is now secured with a nut and bolt, might swap over to a nylon locking nut for something more rugged.

Got my gear ratios worked out so now I am turning my attention to the center pulley and the spur gear (completely belt driven).

This will get done tomorrow hopefully than maybe sunday (fingers crossed) I can have it running. Thats a very optimistic fingers crossed though..

Well I *Finally* have something to show. Digging the purple/black colour scheme actually.

Reminds me of my old e-savage from HPI with its purple anodizing. Still have to figure out the belt tensioners and the front shock mounts...
