Slaonlow has a 38 Mod A-700 need info

I have a 1938 Mod A-700 (so the paper works says) and I need to know what you guys know. This aricraft is in great shape and I want to build it out, I have an a-65 motor and the STC to go along with it. I notice that there are other 1938 models mentioned in the forum, what are the differences?

I need a motor mount and one set of struts and I need to build out one wing before covering.

I'm building wings now and am wondering if there are STC that I can include now for future upgrades etc. HAREL?

I guess I want to begin dialog on this AC and start learning some of the subtle differences.

Thanks

Hi, is the airplane a model A with the serial number 700. If that is the case I am working on rebuilding two model A's and have flown one some. I know of two stc's for the A-65 installation but could only get information about one so far. Talk to you later, Winston.

No. the previos owner compiled a note book that has "Taylorcraft Specification A-700" written on the cover. My serial number is 513 and the tail number is 20511. The documents indicate 1938 Taylor Young Model A. It looks a lot like my previos project except the elavator and rudder have three pins and there is no trim tab. Additionally the yoke looks like a Y configuration rather than a "H" set up and wheel is actually a wheel. It also has the big tach instrament panel.

A-700 is the type certificate number for a BL. The type certificate number for the A is A-643. The A looks about the same, but does have quite a few differences. Tom

Re: Slaonlow has a 38 Mod A-700 need info

Yes, everything you mentioned indicates that it is a model A. The A model didn't have any trim system at all. The original engine was a continentel A-40. The x brace in the structure above the cabin was tie rods instead of tubing. They also had the Y shape yoke you mentioned. It sounds very original with the tach and everything. Those large tachs are hard to come by but I am lucky enough to have one in my BC-65 and model A. If I can help in any way let me know. Winston

I have Model A, not the 700 A, Thanks

The previos owner left some real good parts for me to assemble. Tomorrow I will install both brake assemblies (new linning alread installed).

I need to order new shock chords. I have determined the size and Length for the main gear but cannot find data on the non steerable tail wheel chords. I have a steerable set with a spring but I want to try the original non steerable. Any suggestions? I want to guess that the factory would want to use standard components and would have used one or two shock chords from the main gear.

I need a Oil Temp guage for the instrumant cluster.

I think a good STC that could be easily written is the trim assembly. I'm thinking that I could do that and stay in the experimantal cat until I get a stc approved.

I need a new forward strut and a window pattern.

Holy airplane parts batman.....

Re: Slaonlow has a 38 Mod A-700 need info

Jim, in my opinion if you have a real A model, you don't need the Harer/Gilberti STC. That is for putting the 85-100 horse engine in, which is probably not appropriate for your airplane. You have a rare antique, even among the rare antiques we have. You might want to put in one or two of the parts for the Harer STC, like the large spar root bushings, but if I were you I would not do all of it. You're not going to create a Model 19 when you're done anyway. Having 65 horsepower in a lightweight A model will make it as much of a hotrod as 85 horsepower in a BC-12D probably.

Remember the T-craft was originally designed at a time when most airfields were grass or dirt. A non-steerable tailskid or tailwheel will restrict your flying to grass in many cases. A crosswind, on concrete, with a tailskid, is a formula for a groundloop.

For the trim system, the easiest way and the closest to historically accurate would be to put the pivot in for the little B model flippers under the stabilizer. They are marginally effective on the B models, perhaps they are OK with an A model.

Since you will be creating the system from scratch, IMHO make the trim flippers about 20% larger all around, and put a friction washer (leather washer) on the pivot so you can adjust how much force it takes to move the flippers. The only people who could possibly walk up to that airplane and say "wait a minute, that's not a factory installation!!!" are here on this forum and they already know you need a workable trim system

Based on my experience trying to get a simple field approval for a skylight, I must suggest you stay as far away from the FAA as possible where STC's and modifications are concerned. The knowledgable FAA guys who are willing and capable of looking at an STC or field approval and making a yes/no decision are no longer allowed to do so. everything now has to go through the engineering department, where a 22 year old engineering school graduate (who's never touched an airplane) has to spend 6 months determining whether the sky will fall.

this is infact a model A. I was confused about the early T-Carts and now I'm straightened out. I want to install the A-65 and it looks like I can do that under an approved STC.

But must I accomplish all the items on the STC such as gap seals, electrical system etc? I have to get this part worked out, I do not want to butcher my cowling nor do I want to replace it. I have a lot of reading to do before I purchase motor mounts etc.

Re: Slaonlow has a 38 Mod A-700 need info

Talk to your IA about using parts of an STC. I believe that an IA can write the log entry in a way that says "deviated from STC by notinstalling gap seals, which were not desired by aircraft owner. Not installing gap seals will not have any effect on the other portions of this STC and will have negligble or no effect on the safe operation of the aircraft".

Of course if there is a legitimate reason those gap seals have to be on there with the larger engine, then you need to be sure of that. For example, if the A-65 makes the airplane nose heavy, and you don't have enough up-elevator authority to flare!

Others know far more than I, but I am fairly sure that the 65 horse engine will fit in the open cowl, because there were many open cowl airplanes built with 65's.

Re: Slaonlow has a 38 Mod A-700 need info

Is the tailwheel a few feet forward of the tailpost? I guess it is since you mentioned bungees. I haven't flown an A model with that tailwheel but one that I am rebuilding has that original set up. I may have a temp guage but I would have to look. I do have one front strut though. Let me know if you are interested. Talk to you later, Winston.

Yes it is the Temp Guage that I need for tyhe oldround in trument, I llok at that strut, what do you want for it and what condition. Mine has a patch and is usable but not what i eventually want to have on the plane when it is painted.

JIm

P.S. Yes the tailwheel is ahead of the tail post but hte configuration will also accept the spring assemble. I like the onw that is on it right now.

Re: Slaonlow has a 38 Mod A-700 need info

You should probably come and look at the strut. How far are you from the San Marcos area? I still have to look for the temp gauge. Talk to you later, Winston.
