Default Next generation cooling heads: heatpipes?

Something in my mind for a long time, why isn't there a cooling head with an integrated heatpipe?

https://en.wikipedia.org/wiki/Heat_pipe

Heatpipes are used in today's computers to transfer the heat much better with smaller heat sinks. It could lower the cooling head much more and lower the weight a lot giving a much better CG.

Just an idea...

Interesting but not sure.

1. May violate rules against liquid cooling since there is a small amount of a working fluid in the system.

2. May end up weighing more than current systems.

Who knows? The systems we know from like processor coolers are made from copper because it has a better overall heat transfer but there are also aluminium versions. Regarding the capacity, a lot of cooling is allready comming from the inside with the nitro content.

Other construction you can think of is transfering the heat of the button head (no cooling head mounted) to the chassis plate, with heatpipes it is possible to transfer the heat to any place you want. A very good example are the fan-less computer cases where all the heat from processor, videocard and mempry is tranfered to the case with heat pipes.

OK, it will add some costs. On the other hand people are willing to buy a 700 dollar engine using 100 dollar ceramic bearings for the best performance, so a true low CG head is better to sell than just a 4 gram lighter head by drilling some holes.

Main problem is they are weak, they need a fixed position, and most r/c cars aren't exactly stable when giving out 100% power.

The other problem is, they aren't really that great in Weight vs. Heat transfer
