This section was created by Andy
Hartz in his site International Waters. You may know by now,
that his work and personal life became incompatible with the work needed to keep those
fine pages. The information you could find there was the most valuable one could find
about this hobby.
All of those that try to keep interesting and accurate WEB pages know how huge is
the work involved.
This is an attempt to keep such fine work from
disappearing. Aeromarine

ever built for speed. The best part is the sound!! I'll be putting video and digital

The prop angle I am running makes this boat very fast, however,
when accelerating the boat wants to abruptly turn left. If you have any suggestions why
this boat does this please e-mail me with these or any other comments on my boat. |

I put the fuel tank I little bit higher, better for fuel flow. Add
a persplex cover for my rc compartment I made a new water pickup, beside the engine, Look
for pictures soon on our page

Since this boat has a high profile, use a couple of degree of
negative prop angle to help keep the nose down. The engine is as high as it will go. |

Close off rear of top cowl fin - looks better and air pocket

My community association is threatening to outlaw radio controlled
