Well Bob Z. finds bargains at garage sales. This is what I found this evening picking up some plans that I had laid on my scrap balsa box. It is the "Dynamic Models Tech-Tip Manual". Had to have been in 1958 or 59 when I got it from them. If you look close there is no zip code and names for the phone number instead of area code. The index shows:
1. Catalog Sheet showing the Holland and Johnson engines.
2. Tech Tips A thru f or No. 1 thru 6.
3 Parts Price List for the engines
4 Parts Price List Johnson Flying Lines.
Idon't know if posting on the bay would get a decent price or not.
The original bubble packaged Fox .35X had a double race of needle bearings! These were flexible for those of us who wanted more than just go fast engines! I had a .35X single race needle bearings on a Goldberg Shoestring which I flew so much that I wore out two bell crank assemblies before I learned how to bush the aluminum with brass sections peened over! These now last longer than many planes! If two or three head gaskets were added under their heads they would make a fairly decent stunt engine! We'd go to the local chemical supply house and but 3 gal's. of methanol, one gallon of Bakers AA castorloil and mix it up in a 5 gal. pail and go fly most of the summer! Price for the mix was not over $5.00! That's about $1.25 per gal.! Who needed Nitro? Winter flying was another thing!
