bought microsizer..swapped pcb's w/zz
 

I went to my local hobby shop and saw that they had several new microsizers in, well they use to want $35 for them, but due to poor sales the guy gave me one for 25. the speed was awesome, i must say it ruined my outlook on zip zaps, but i missed the look of the zip zaps, and the handling, so i said screw it im going in, after some serious tweakin and modding i got the boards and motors swapped. Now my zip kicks a** if you know what i mean. Im gonna take some pics and post the way i did the board, its so clean it looks like it came that way. And while I had it apart i soldered a new antenna on, a single strand of 10 guage wire, then ran it through the snap thing on the plastic cover, melted it together so it would stay there, superglued some shrink tubing to the body to feed the wire through so it wouldnt flop all around, i love the speed, and i actually think the cotroller is a little easier to use, oh yeah, i had to mod that a little too so it would charge. i clipped a little of the plastic nub that sits right above the charge tabs so the zip would go far enough down to enable the charger, im gonna try to get another board and motor from a broken microsizer so i can do all the same to my other zip, im spoiled now, wont go back, the stock micro was much faster than my red, or nos motor with any of the gear combos, So im running a 49 mhz zip, with microsizer stock board and motor, red gears, also using the micro battery too. I have 7 bodies to choose from, all the tires, hubcaps, and gear sets, so im set for awhile, anyone with a spare micro board, its well worth the trouble. back tomorrow

Did mine too!!
 

All I can say is :eek:
Couldn't believe the diffrence.

alot better than the reverse mod???im not to impressed at all with the zip zaps...im running a 3.8 mottor but still there is a difference between the bit and zip...you can hear and see the differance..if i put the bit board in the zip board would it make the zip just as quick ...got a free chassis from microsizer comming so i may switch ..:-)

Way better than the no reverse mod
 

This is the way to go!

Handles better than a bit at high speeds almost instant top speed. Made mine so the zip controller works so looks stock till I hit the juice.

Well worth doing this mod and after this mod addind LED's is a snap because this PCB is so simple. :D I did mine last night so later I will and some tips and pic's

so the 27 chassis will work with the 27 mhrz zip ???the zip controller will work ??
yes pics tips and hey ..why not just do it for me ..j/k .//but all the help would be a help thanks

It will work
 

Yep a 27mhz bit PCB will work in a 27mhz zip.

The most important tip is to TAKE YOUR TIME!

1st I opened both PCB covers a looked very carefully to see wire configs. then I made a small drawing of the bit board and marked all wire colors on the drawing so I could refer to it during assembley. Pay attention to the layout on the bit PCB the only wires that are diffrent colors are the motor contact wires. Remove the wires from the PCB (Bit PCB first) and have the Bit PCB ready to install before removing the wires from the Zip PCB.

The one step I was very careful on was when I removed the +red wire from the zip board(there is also 2 steering wires here) I imediatly soldered the 2 steering wires to the red wire to make it easy to install to the bit board without having to guess which wire went where. This mod is very easy with a little patiance. I soldered the motor wires last because I reversed them so the zz controler fwd and rev were correct. Thats all there is to it. I did not have to change steering coils or contacts just the PCB's.

Things you will need
15watt solder iron low heat so not to add too much heat to the PCB.
Tweezers to hold and control the steering wires
And thin silver bearing solder

If anyone is good with tech. drawings and can provide a layout of both PCB's I'll add touching points
