Question And Answer Box We are starting a question and answer column to try to clarify

various problems of the readers.

and the internal drag trussing certainly looks able to cope with drag loads. Answer: The drag wire was used on the original tests and has since been removed. Question: I'd like to know how

We don't profess to know all the answers but will do our best. If

you trim the Ace for cruising and

we get stumped we may turn to some of you for the answer. Question: Why does the tailskid of the Baby Ace hold the tail so iar off the ground? Does it have anything to do with landing angle that requires it to be that way or

stabilizer or trim tab adjustment.

is it just coincidence that the Cub

assembly hold it that high? Answer: A J-4 cub coupe tail spring was used which has since been shortened 2 1/4 inches which

gives a shorter takeoff roll. It was noted that ground handling in higher winds was slightly better with the tail spring in its original

conjuration as the wing angle of attach was less. Question: What is the purpose of the drag wire running diagonally

between the Baby Ace wing struts? It looks rather out of place all, quite a few modifications such as the engine change, tail surfaces, landing gear, cowling, weight changes, etc., and according to some of the data we were able to come up with it appeared that it might be the fuselage of one model and the wings of another. The result was I was required to make up a name plate bearing a name, model number, serial number and data of manufacture. I used my own name and established a model and serial

number which makes the plate read as follows: MURRY MODEL

MC40, Serial No. 100-1 Mfg. 7-755.

On Sept. 28th the CAA Safety Agent, Mr. Corso issued an experimental license and airworthiness certificate. This leaves me with 50 hours of shake down and no place to go. All this has taken a lot of time and sweat (the sweat came easy during July and August), and cost??? It may be just as well not to know exactly. As a means of air transportation, lets face it, it isn't worth much. As near as I can calculate it cruises about 70 mph and consumes about 2% gallons per hour. It carries

just under 6 gallons in 2 wing tanks which will run it about 2 hours. There is one common question

that nearly everyone has and that is how I get my 6 ft 1 inch into it. It is a pretty good trick. All considered it has been fun working on it not to mention flying it and

I think it is going to be fun having it around for awhile.

various throttle settings with no Answer: The Baby Ace incorporates a ground adjustable stabilizer. After the first few flights the stabilizer can be adjusted with the use of spacers or washers for level flight. The pilots weight and use of fuel do not change the stick pressures enough to make it uncomfortable. Over 40 pilots have flown the Baby Ace

without any change in stabilizer adjustment and no comments were made on stick pressures. Question: I'd like to read a description of the Baby Ace's takeoff, stall, glide and landing charac-

Good Design Practices For Aircraft must be double. Control surface hinges must be rigid to prevent flutter. There must be no interference between rudder and elevator at any point of travel. There must be no change in control wire tension as levers, horns and surfaces move through their arcs when controls are operated. Fairleads may not be used in place of pulleys to change direction of a cable except in cases where there is less than 3 degrees change. Electric arc welding is not allowed except where specifically ok'd. Wheels must be CAA approved types. Welds must not be filed or ground. Suitable drains for condensed moisture must be provided throughout the airplane. Cockpits must have adequate turn-over protection. Tensional stiffness of wing, fuselage and tail surfaces must be adequate to prevent flutter. Carburetors must be drained to outside of cowling. Fuel lines and tanks must be arranged for proper fuel flow in climb, glide and banks. The foregoing are just a few of the good pointers on safe design you can get by studying CAA publications. .. .why take a chance when years of experience are available to you through a few
