Problems

Cessna 185 on EDO 3500 amphibs
Author Last Post
I found the problem with the help of JJ Fry. He of course has seen it all and said my problem was exactly like one they had years ago on a 185. To make a long story short, there was a bit of wrinkling , about the area of my hand right in front of the rear of the step . It was a bit of distortion that looked like it had sat on or rolled over a rock.It was less than 1/4 in deep , max. We puttied it flat, seriously less than two TBS of material, repainted and the performance improved by 40%.It was unbelievable this small distortion could make this sort of problem. We have all flown floats that looked like they had been to a demo derby. These ones looked like new when I bought them!!Overhauling them this winter, need bow struts or parts and will check to be sure the wheels also are fully retracting Thanks for the suggestions and info!!
 

A few questions so others may be able to help;

  
Altitude & temperature at lake
Diameter of prop & rpm at take off
Do you have wing extensions or stol kit
Flap setting
Weight at take off
Where is the c of g
Have you placed the aircraft on a dolly to cycle gear to see if it is completely stowed

Not everyone can afford the aerocets 
 
Bob,
 
The fix is Aerocet 3400 Amphibs.....Seriously, the EDO 3500 amphibs have a poorly designed step/wheel well and the drag is an issue.  You might check that the wheels are retracting fully to the 'up' stop, as if they are improperly rigged, they may extend slightly which can also increase the drag on the step.
 
Amphibs brief well, but the reality rarely meets expectations. 
 
Good luck!

I have recently put my 185 with a factory I0550 port/ polished, Leeds exhaust on amphib EDO 3500s Its the most water loving difficult@$#^%* plane I've ever flown of water, including Norseman!!
I have the EDO drawings but my AME says so far he has been unable to find much on rigging . I think it needs the nose lifted up to get some lift as it comes upon the step pretty quickly and then there is no sweet spot and it just burns up lake at 50 and has trouble accelerating. LOADS of power so I think the plane/float incidence is actually holding it down on the water. Does anyone know what the recommended flying wire measurements fore and aft are??They are boxed/ matched but may be wrong...
