Some pics of my mods...
the heatsink bolts into the frame at the engine mount holes (a bit of notching and it fits) the small piece of duct tape keeps the top cover from sliding forward...you can also see the CAPS are epoxied together (they are quite stable and fairly out of reach of the lid)
here you can see the notch in the side extends halfway across the bottom, exposing the solder point for the positive side of the CAPS and power input (otherwise this is unaccesable after the epoxy sets...) (yes i need new diff)
I like the low, centered COG with this install. The top 3 CAPS are along the center line and it all fits nicly under the top. Looks like I have a 'punk' Quark! (it has a mohawk)
Handling is spot-on and balance is very close. (need to change reciever pack and location for spot-on balance)
