From Nick –
I thought you might be pleased to see the attached photo from our recent maiden voyage. I built the Power 225 from your book as a project with my young son (hence the colour scheme!). He much enjoyed sticking it all together and the photos in your book were ideal to show him the building sequence and keep him interested.
I couldn't get hold of your recommended power plant (I think Graupner have had some financial problems) and I ended up fitting a direct drive Speed 400 powered by a 2 cell LiPo battery. It went like stink! I also fitted the spray rails as you suggested, but they can dig in at very fast speeds and caused some minor handling problems.
We will shortly be starting on a second one for my other son..
Thanks for the design.
