Building my M1B-Turbo: Technical
I decided to start a technical thread for build tips for the M1B-Turbo. I cannot seem to find decent tips on the M1B-Turbo as its so new.
I have just recieved the car and have some recommendations and questions. If you have a M1B-Turbo then this is where you at.

Day 1 and 2
The packaging looks the best but that we know. The Turbo seems to have all the upgrades to the old M1.
The CVD's looks decent all K-factory. The suspension arms looks very nice and has alot of flex.
I am about half way through, had my first problem with a duplicated part and a chassis brace that doesnt fit. Other than that everything went together very well.
The shocks though is an issue for me. It comes with front and rear shocks the same length and you use the shorter springs for front and long for rear.
Also mounting the shocks was difficult I struggled to get the shock standoffs into the shock cap. It seems like a trick to get the standoffs into the plastic bush then with force insert this into the shock cap hole.
Finally managed it.
Diffs and drivetrain is nice and smooth.
The steering mechanism IMO the best ive seen. Bearings and bushes in the right place and no friction on the steering at all. very smooth also.
The way the rear suspension arms are held together is magic. The best ive seen so far. The rear toe in plate has a platic insert, you pop a ball into this insert and the hinge pins slide into the ball. No need to file or loosen any arms. Just resistance free.
I am taking pics to share butwill keep interested parties informed.

Ok Got as far as putting engine in and making up linkages. I went for a basic spray job.
I have included some low qaulity pics. More to come later
PS: problem: Looks like a standard JP3 pipe has a problem fitting in this buggy. Pics of M1's shows all none rounded headers. What to do now?

Looking good JB
For the pipe problem there is only one solution and that is cut the body to get the clearance.

Finished the car and took a quite spin in the backyard.
The setting up of the steering servo is very tricky only one way and if you do it wrong you dont get full steering.
I modified the exhaust header a bit to be able to fit it all and is ok.
One thing I nitoiced is that I had to retune the engine after installing it in the M1B turbo. Tank pressure etc does play a big role in engine tuning.
The body with its stickers looks kicker.
I havent had it on a track but just from playing around I noticed that the M1 has very quick acceleration. This must be drivetrain related.
Testing and more testing.

make sure you put on the shock protector , because it is an integral part, adds to the strength of the front bulkhead and you need to cut away the thinner section of the rear chassis brace for more flex or even take it out to help the rear track better

definatly a sweet buggy to read about, new and totally different to any other, have been close to buying one but didnt at the time due to part issues which have been fixed now.
happy with wat i got now so ill stick with it.

I also noticed the chassis plate below where the droop screw are is half thickness. This definitely looks like it may wear out quick.
Let me charge my high def camera and I'll post some interesting things I noticed.

Here you can clearly see the pipe touching rear torsen bar.

it doesn`t effect it in anyway in fact you could take ouy the sway bar altogether for more tract

I find the acceleration is awesome very quick. Although I find the car being very tail happy. I am running 5-7-2 and 30 wt shock oil.
I think maybe 50 40 shock oil also take some droop out.
Everything else is excellent. OK just the battery box I dont like. The pack is a very tight fit and I need to get battery box for every pack for quick change over. I am thinking rather swop battery with case as the case isnt very easy to open and swap battery.
Now to check laptimes!

The M1 has a lot of steering and it will make the buggy tail happy.
Take away some streering by going higher on the front diff oil.
My M1 and M1-B are running 7/5/3

I have noticed with th stock setup that there really isn't any sway, no matter how you adjust. I have gone so far as to cut down the ball cups. But, I don't think it will make a difference. The COG of the car is so low, do you really need sway, and if so has anyone tried anything else? By the way I am running 60wt. Associated oils in fr and rr.
