Jan, Mr Krabs is finally repaired and I am taking him to the pond this morning for more setting up tests. Trying to get maximum speed from him before I put the fast motor in. The problem is I am shooting in the dark as there is no real guide to strut depth etc. I will add a bit about how I solved the problem of the sponsons sliding off the end of the CF booms on the Mr Krabs thread when I get time.

Aside from the plastic spacers (which are always WAY out), the rod supplied with the Top Flite magnetic balancer usually isn't straight, and it's a pretty soft metal. Read the book chapter I did on prop balancing. Steve has a copy on his site here: http://www.offshoreelectrics.com/inf...andbalance.php and you can find copies elsewhere (Google for "andy kunz prop balancing" to find them).

Oh yea. Have to work the last bug out. The steel I was using is not pure enough to balance perfect. I ordered some high quality tool steel which will never wear out. Will be end of next week till I get the ends ground. Have the aluminum housings already finished.Comment

Also, if I can offer some advice... On the balance rod... You will geta more accurate balance if you turn down the ends to a smaller diameter and eliminate some mass along the length of the rod... Leave a section of 3/16" in the middle to hold the prop, but turn down the reast to 1/8" or ???
Not sure if that will leave enough material for the magnets to hold it up, but if it can, that would make this more precise...Darin E. Jordan - Renton, WA
