Steve;
In regards to the 337 you've posted regarding use on a Brantly for trim, I feel it is not appropriate to post as it is without an explanation attached. As it is , it can be misleading to anyone reading it. The A/C the 337 describes does have this grip installed, controlling the radio only at this time. The trim to be used in parallel with the floor mounted switch, requires the use of two additional relays in parallel with the existing circuit, to prevent smoke in the cabin, from the switch and wiring melting, when attempting to control the trim !
It isn't that they can't use the grip, the problem arises when, they fail to realize that the switch and wiring aren't designed or rated for the amperage of the trim motor, without using relays rated for this load. As I'm installing this function in N888CF, I'm in the process of selecting relays and updating the 337 with a schematic and parts list reflective of this modification.
Just wanted to prevent a real surprise at 500 ft. Safety our # 1 concern !
Thanks, Bill

Thanks to Steve for originally posting this and Bill for this heads up. The Cyclic Grips are awesome and would be a must do if come across the Brantly of my dreams lol.

Bill,
As finicky as FSDO's are these days do you think you'll have any trouble getting this approved via a 337? I hope not as this is a great alteration/upgrade.

I am interested in installing Infinity's too. But, I have been reluctant because all of the mechanics I have talked to have mentioned that it is difficult to get field approval. If anyone around the D/FW area has any insight, please let me know.

I would like to have radio, trim and landing lights on mine.

Thanks, and fly safe, John

Sorry to have not replied, have not been to the site for quite a while. Will forward the info on the grips to those requested it when I return to Dallas in about a week.
