Hello to all, I am a new builder of a -4. I started about 4 months ago, and am about halfway through the empennage. I have a few questions for anyone out there who can provide some advice since I have never done this before....First of all, should I go with manual or electric trim on the elevator? I am planning on keeping the acft as simple as possible, however I would like to hear any opinions on the pros and cons of both. Also, I will be ordering the wing kit shortly and would like to know if the pre-made spars are worth the cost. I enjoy the building so the thought of doing these myself is not that daunting, but it would be nice to hear from someone who has put one of these together if the time/difficulty involved makes it worthwhile to just get the completed assembly. Thanks in advance for any help, and if there are any other -4 builders in the seattle/tacoma area I would like to hear from you. (I am in Puyallup).
