Pathfinder MK 1 and 2

[Ross Smith]

Hello. Could anyone please outline the main differences between the Pathfinder Profile ARF , and the brodak  kit which is labelled Pathfinder MK 2?
Thanks in advance .

Your best bet is to call Brodak. If you have the choice buy the kit. Maybe the MK 11 stands for Appearance points.

The MK1 is the first version published as PathFinder PRO-file, in Flying Models. Kenn Smith, now deceased, released a run of 200 kits of the MK1 from his company, Smith Models around 1995. The MK1 had a longer wingspan than the MKll and used a wide, notched, single spar that allowed a twist and lock method for installing the ribs. It did not have a sheeted leading edge but instead, used half ribs.

Due to the feeling that the spar may be a possible liability Gordan had me make a few changes to the plans that are used on the Brodak MKll version. Basically, he shortened the wing, and went to a C tube, leading-edge. This made the wing stronger, and less liable to flexing.

If you go to the vendors' corner, here on Stunt Hangar, and look under CadClassics, there's a pretty complete history about the Pathfinder series that may be of interest.

I'm attaching a picture of an MKll  converted to an electric Pathfinder Twin, built by modifying an ARF

Thanks for the comprehensive information I received from the replies. I have all the information I require. I have an ARF which is my practice plane, as well as a new kit.
