My 2 cents: spend a lot of time on a flat and level table (saves loads of time in the future if you know your table is okay); get a bench band saw with metal blade - mine was pretty cheap (less than $100) and it really saves time when making or finishing attachments etc; also I find one of those little bench sanders helpful - one with a small vertical belt and a side disk - makes finishing small parts easy.

Which is considered correct?? My view is that four would be proper in order to NOT put tension on the coils. However, there does not appear to be quite enough thread length for the four. I only have two, I can get two more, they sell for about $9.00 each (that's a bit steep). So what's the opinion of the list? 68 degrees and bright sun in North Texas.

I would suggest using it for the passenger side and drop a G205 on the pilot side. But if I were to do it again I would have bought the G207 for the pilot side. The extra 2 switches for avionics control would eliminate the cross arm reach to get to the radio just to flop from one channel to another.

Seal-Send-Time: Sun, 25 Jan 2004 13:12:58 -0500 --> Zenith-List message posted by: "LARRY BOHANNON" Hi List, With all this talk about engines and a recent article in Experimenter magazine I've started rethinking whether or not to use the 100 hp 912 or the 80 hp 912 in my 701. In the Experimenter article the author stated that he thought the 100 hp was too much for the plane and recommended the 80 hp. unless you were going to fly on floats or high altitude areas. Even before this article, I read on the ZAC web site that they also recommended the 80 with the same exceptions given. Then, a few days ago, I read the article on flying the 701 by the Australian guy that someone posted a link to on this board. I think he was flying the 701 with an 80 and he even thought that was too much and he was guessing that a rotax 612 ?? would be about right. I don't know what the Hp on a 612 is but it must be less than 80. I want to go with a 912 but now I can't decide between the 80 or 100hp. I had just figured for an extra $1500 that I would go with the 100hp but now I don't know. My background is in hang gliders during the 1970's and ultralights in the early 1980's so if it were possible I would really like to forget about hassling with an engine at all I want to go low and very slow and I'm not concerned with a fast speed so it would seem the 80 hp would be right for me, but we get awfully hot and humid days here in Georgia and with a starting MSL of 1000 ft. those hot days would really increase the density altitude and also I'm installing a BRS chute so I might weigh in a little heavy, so.... then I think I should go with the 100Hp!! So, what does everybody think? What are your opinions and reasons for either choice?

The 40 may not be accurate....it may have been 46 or 52 or thereabouts, but it was far less that 80. It seems to me that the first 701's used the Rotax 582 (?) and got around quite well. At any rate, 80 is plenty.

A set of switches on the panel is not a bad idea. But with flap control and throttle I would prefer to keep my left arm as free as possible to perform all other functions. Switches on the panel is just another duty for your whole arm to perform as opposed to a thumb movement on the right hand. I've read that some found the trim switches located on the grips a bit troublesome in rough air and also with conversation with the tower. This can be true if one tends to fly with there thumb on top of the stick. And accidentally trip the trim switches. The old style of PPT switch didn't have gold contacts and was prone to bad connections but I was told that, that was taken care of many years ago. I'd just recommend putting the trim switches away from the stick where the other hand can do the occasional trim and have only the PTT on the grips. Both ways will work equally well, personal preference is the deciding factor. I prefer the convince and simplicity of the grip mounted controls, Larry prefers the panel mount. My suggestion is to sit in your seat make propeller noises and see which hand is more comfortable to move for the desired task. One note while your in your seat ! Plant your back firmly against your backrest as if you have the shoulder harness done up real tight and make sure that your left hand can reach ALL controls on the panel/fuel selector/shutoff as well as the placement of your fire extinguisher. This may not be as important in the U.S. but if your building a homebuilt in Canada it will be part of your final inspection! IF you can't reach and operate all controls to your plane without releasing the stick then you can't fly either. No intention to criticize your preference Larry, I just wanted to offer more options.

Ideas appreciated ! > > Ron DeWees > 601 HDS/TD -Jab 3300 in progress I looked at a few different ways to put the 4-way trim switch, a PTT, and a radio frequency toggle switch on the grip. I ended up using a gearshift handle from Pep Boy's. It has 2 plastic half-shells that can be removed allowing access to install the switches. The OD of the handle press-fit snugly inside the ID of the 1-1/8", but I did have to cut a few inches off the end of the Y handle so it didn't end up way too long. You can see it in this pic, the 4-way trim switch is in the middle with the black radio freq toggle switch on the top and the red PTT on the left side. http://www.lightflyers.com/zpanel.jpg Rick P. ________________________________ Message 18 ____________________________________ Time: 06:07:59 PM PST US From: "Bill Howerton" Subject: Re: Zenith-List: Engines: 701 80hp or 100hp ???? --> Zenith-List message posted by: "Bill Howerton" While I'm building a 601XL, I think the engine choice options for the two planes are similar. I'm looking for more horsepower primarily because of where I live. I live in a high-altitude area, Colorado Springs, and typically fly when density altitudes exceed 10,000 feet. Furthermore, if I want to fly west over the mountains, I need to have an engine that can get my plane above those 14,000+ feet peaks.

Most of my wiring is run through the cable tunnel area through the center of the cabin. However, there's not a whole lot of room, so I doubt you'd be able to fit the battery cable in there as well. I'm still not sure where my battery will be with a Corvair engine, so I'm holding off running that particular cable. I've managed to squeeze the wiring for the rudder position light, all the wires for the flap controls, and the elevator trim all through that tunnel. I housed the wires in some flex conduit to protect them against any rubbing against the control stick. So, if I have to locate the battery in the rear, I'll probably run that cable along the inside of the fuselage on one side, and the antenna cables on the other, for lack of a better plan.

If you don't want to make your own heads, the ones from ZAC fit it just fine. The expensive riveter will pull larger rivets, but you won't need that capacity for 99.5% of the plane. I like cobalt drill bits and find they stay sharp longer the the TiN. A step drill bit is also worth its every penny they cost. They drill large holes without grabbing. Aircraft Tool Supply has been a good supplier for me. The have great prices on clecos, drill bits and other special tools. They are at www.aircraft-tool.com.
