#1 the linkage needs to be strong. Also needs to be maitencance free as you won't want to take it out and look at it every week. If I used a MK unit I would use the Central Hobbies 3/16" CF pushrod with a 4-40 Titanium fitting...Then use the MK MKD0891 BB rod adjuster 2.5mm


This BB rod adjuster is a Ball link type device...I would lock tight the nut and screw securing the link to the MK center horn and use that.


Dave Brown arrow shafts will flex cause the 4-40 rods to weaken and fail. This is the place for a CF titanium fitting above all other places....Many people have lost planes not installing this MK device properly or using it properly.


It works very well and is a good product...but has to be used properly. I don't like cables but many people think that switching the MK to cable control inside the fuse is the way to go...


I have a better solution that is lighter and much more positive than the MK...It takes about 3 times the work to build and install. Its not really any cheaper but I feel its a better design.

The MK is probably next on my list of choices... It super simple to install has a bit of a $ tag but is defiantly superior in all other ways to the Dave Brown Arrow shaft. Just because they are black don't mean they are CF...they are fiberglass and flex a ton.....You need a good support system to keep them from moving.....

This is my opinion and other have theirs also....but it is worth exactly what you paid for it.....the advice that is!...LOL
