Mikael Sundgren 1950-2019

We have lost a big RC boating profile!

Wednesday August 21 we lost my friend Mikael Sundgren after a short illness.

I've known Mikael since the mid 80's when I shifted to hydroplane RC boats from racing off-shore boats before that. After we booth made a comeback to boating some 13-14 years ago, me and Micke have shared many trips to the ponds and races around Europe. He was the one I discussed technical solutions with whenever I had some doubts or that I just wanted his opinion.

He has also been very helpful and influential in the development and testing of all KEP's boats.

I've lost one of my best friends.

R.I.P.

The funeral service will be held at Pilgrimskapellet in Järfälla Wednesday September 18 at 13.30.

More info of the funeral service can be found HERE
