Its been a while since the release of the graupner Daytona beach,
and since there are more and more daytona's popping up lately its time to find out if we can better the reputation of the infamous Daytona Beach..

First, get rid of the annoying chining and diving of the hull,
the chining is due to the high placement of the engine,
so thats an easy fix, the diving is due to a hook in the hull so puttying is the key here..

First, get rid of the hook in the hull, the stringers can be a grear help here,
also they are used to place the engine about 5 cm's lower,
this helping the all together CG, and getting rid of the chining...

The original hull has quite a hook in it, get rid of it using the stringers and afterwards puttying the hull straight,
all of the running surface has to be straight...
The kit drive from Octura is useless, too near to the hull, use an MTC or a MHZ one,
I used the MHZ Middle trimax, and it proved to be the way to go...

Also the original rudder is to near to the boat but is evt usable..
If budget is a problem a simple strut will do fine just keep the dogdrive 7 cm's away from the stern..
CG is about 25%, so trimflaps are needed, the Aeromarines will do fine but I prefer the MTC ones...
Radiobox can be difficult of the limited space, build one yourself, or get a small one from AC or aeromarines..
Steering servo needs to be 12 Kg/cm ++... Thottle servo can be a standard one...

T his way the Daytona can take a lot more engine and power and runs really a lot better than in the original kit form..
The official top speed is 93 Kph ran on the Dutch SAW.... i think thats OK for a Daytona powered with a 231 engine !!!!

Reccommended props so far, Prather 270/275 ABC 2714, 2814 Propshop 7015/2 7015/3.

Update 14-11-2004.

The first test run...
After starting the first run, unfortunately the plastic linkage on the rudder broke because of a high smash on the water. After repair, the exhaust cam loos, on the second run.
And i wanted to try out another prop.
This test run started not good.
After put it on shore i also saw that the bushess from the trimax came lose, so i had more to repaire.
Bad starting day.

Any way...from the first view....i think the changes has made progress.

Update 06-03-2008.

Time to paint the Daytona and make a new test run.
Hopefully this time nothing breaks or come lose.
