Nuckolls, III" Subject: AeroElectric-List: Ducatti R/R deficiencies I took some time to finish an article I started some years ago explaining my perceptions of thermal management deficiencies in the Ducatti R/R supplied with Rotax engines. http://tinyurl.com/zvkoh4p If anyone finds that I've stubbed my toe, give me a heads-up! I've got another one that speaks to the practical application of 'filter' capacitors on the output of rectifier-regulators for PM alternators . . . but that one will need to wait a bit longer.

I have a Rotax 914 and built my plane in France, there their comment was to only allow for a max of 14A out of the Rotax electrical system and then if only the wind was blowing in the right direction.. You can see what Schicke was endeavouring to achieve with their cooling, I do not know how robust their solution is under their potting mixture.

It's almost a certainty that this product maximizes benefits of that very robust heat sink by bolting the 'hot stuff' right to the metal. Schicke and Silent-Hektik are probably only two of many folks who have slain the R/R dragon. Thanks for the heads-up on this product!

With ROTAX planning to roll out the 915iS with the Garrett Turbocharger much like their 914, additional heat is exactly the issued needed to be addressed by Airframe designers. They are quoting over two dozen manufacturers planning on using the new product when released. My question to them, still using 20 year old technology with these Ducati parts? As always, your perspective makes this discussion more "On Point" and valued. John Cox On Tue, Sep 6, 2016 at 2:02 PM, Robert L.
