My RWD solid axle front engine Escort MK2 build


Frederik

Recommended Posts

Thanks a lot guys!!

I have just weighed it yesterday, with on board all parts I could think of that will be used, it currently weigh at 4 lbs which is not all that bad I think :) I left the masking tape body shim in there just to account for some of the added crap I will add lol

Not sure how much weight is a regular 1/10 car with battery and everything loaded though, I'll have to weigh my 1/10 Tamiya TB-01 Rally Subaru to compare I guess.

Quick view with body on and the high offset wheels in the back (and less offset in the front). Also I loaded the car with some parts to compress the suspension a bit :) though the front is still high for now.

Wow!! Just wow, simply a epic build.

 

Thanks a lot guys!! I might not be able to progress much this week on this project, but I'll keep you updated as I go. Next I am going to sort out the lower arm length and then fab a lower cross frame to hold the arms.

Thanks a lot for the kind words Ben! I guess the rust appearing everywhere adds to the realism too :D Hopefully it does not rust through and need restoration before it is completed hahaha

Update! I thought I would have to use the tamiya avante ball links instead of the RW4WD ones, but they ended up giving just the right amount of movement, provided the arms are short enough to give some negative camber when compressing, and positive camber when in droop (which is what the real escorts do anyway with their short arms).
 
I made the lower cross member as well as another cross member up front where I will attach the sway bar (which will at the same time triangulate the control arm).
 
I think I got the geometry pretty right! The wheel tucks in the fender nicely when compressed.
 
 
Here is the first cross member, kind of dummy for now but it helped put the main cross member and keep the right width between frame pieces:

The main cross member partially made:

And the pretty much finished piece:

And here is a short vid of the strut movement, of course I will need a link to prevent the link from moving fore-aft:
 
 
 
 
That's it for now! The cross member was pretty long to do, I did not want to mess up the dimensions and geometry, I am very happy with the result!

Gobsmacked!!! What an interesting thread..... I have had a Mk1 and Mk2 Mexico's,Daytona yellow and Signal orange.I also worked at F.M.C. Dagenham,they had a building the called  the the "hush hush" where they did a lot of their initial R.S development .Needless to say I spent quite a bit of time in there (helping out)

Great work as ever Frederik

 

the front bar links look fine with the rear mount and should clear the steering very easy.

wheels sit perfect into the body on compression and have that droopy dogleg look when relaxed. 

 

the machine is coming along very well , keep up the hard work

I Have only just seen this it looks brill

keep up the good work

 

 

Thanks a lot for the comment! Glad you found the thread and decided to chime in!!

Thanks buddy! It is nice to have feedback from full scale enthusiasts and see you like the project! Thanks for following!

Yes I like the funky angles these escorts get on the front suspension on full droop, and the steep angle of the A arms when unloaded. This contributes to the high roll center like the real thing, I think I got most of the suspension geometry right! I would not be surprised to see it turn on 3 wheels! :)

 

It is quite some work but when you enjoying it is never seems like too much work, especially with comments from people like you! Thanks for the kind words guys!

For a steering rack, I thought I would be using seals similar to shocks, at either end of a rack, so it would slide nicely, and possibly using bearings, but I found in my parts some shiny shaft probably used in some touring car's drive train. It just happens to fit exactly inside of the larger size of brake line I have! And it slides effortlessly!
 
Just need to make a slot in the brake line, put a screw in the center of the pin, and this screw will be what the servo will attach to. Then the servo would be where the radiator would be, servo horn facing down. I imagine a steering system similar to kid's pedal car, if that makes sense to you.
 
On to the pics, and the now usual video :) I guess videos are useful now that things get moving (literally) !

Mini-z, Bicko, Optimus, thank you for the nice words!! I have not been able to put much time lately on it, hopefully will this week.

 

I put some oil in the rear shocks (they were new and never filled), and also started to play with servo placement and think of how I will attach the steering servo. It will be under the dash, and a rod will push on a pivot arm to convert the longitudinal rod movement to a lateral movement, and put a small link on the output pivot arm to move the steering rack. It will be clearer when I post pics :)

 

Thanks again all for following along even if I am not really a quick builder!! :)

Absolutely gobsmacked by this build thread!

 

Fantastic work, Frederik. Can't wait to see the finished model.

 

I get to see Mk1 and Mk2 Escorts rally in my hometown when they do a stage along the seafront. Always my favourite cars to see running.

Zardoz, thanks!! I would certainly love to see these in real life, they are so cool cars. Glad you like my project!

BenK, thanks to you too! with the holidays there is a bunch of stuff going on and even though I am on vacation since dec. 20th I have not find any time to work on this.. The 2S lipo saddle pack is in along with the lipo charger though! Still quite some work to do before I can put these in use, and I dont really have any esc suitable for it so I'll have to look around.
