Lynford. . .thanks for your perceptive post. Now I sort of feel vindicated. Yes. . .whoever does not try the recommended procedures first, is probably not in the best position to suggest alternatives. Honestly, the Formica/balsa combo is so darn simple, I can't understand the resistance to just doing it. -- > From: Lynford Disbrow <[EMAIL PROTECTED]> > To: Harley Michaelis <[EMAIL PROTECTED]> > Cc: [EMAIL PROTECTED] > Subject: Re: [RCSE] Molded RDS pockets. . .problems. > Date: Thursday, August 12, 1999 4:37 PM > > Harley: > > SNIP > I swear I can make a beautiful set of 4 in 1/2 hour. > END SNIP > > You slackard!

Harley: SNIP I swear I can make a beautiful set of 4 in 1/2 hour. END SNIP You slackard! I can make twenty pockets in less than 30 minutes. I use a table saw and a two foot square foot of formica I got from a cabinet maker (free). I have a lifetime supply, but they are not ARF. You have to mount them and I just can't bring myself to do any building what so ever since I am a pilot 8^) Oh gee what should I do???. Kinda funny isn't it. You tell someone exactly how to do it and rather than do it and go fly, they tell you how to do it better without any testing or experience at all. I tried the wire frame bit when I was testing the prototypes you sent and it was really bad for all the reasons you gave and with much force it tore out of the balsa. To make it strong enough you had to put plywood over and under it ... gained nothing. Now we will probably hear twenty ways to make it stong enough, again without any testing. Such is RCSE.

[RCSE] Molded RDS pockets. . .problems.
Bill. . .believe me, a molded pocket was seriously considered and deemed impractical. Let's see. . .depending on aircraft size and the application, possible shaft sizes among commonly available wires/rods would be 1/32", .047", .055", 1/16", .072" (2-56 rod size) 3/32" and 1/8". Besides those there are the metrics. How can a manufacturer possibly know what size shaft the modeler will select to use? How could a manufacturer possibly know what size pocket to put in a package? If a big array of alternate sizes (the expense would be horrendous) were offered how would a builder know which to buy? How would a dealer know which sizes to stock? Of course, for best operation using a given shaft size, the pocket configuration is different for ailerons and flaps, so we are talking 2 pockets minimum, not one, if a pocket for some specific sized wire could be settled on. How is the manufacturer to know if a pocket for flap or aileron useage is to be included? Include both? Why should a builder have to pay for something for which he has no use? Sure. . .just molding up a perfectly fitting, undistorted pockets sounds easy. However, due to different coefficients of expansion between metal and plastic, you might have a good fit in some narrow temperature range, but a poor one either side. Even a .001" difference is noticeable. The Formica, SS rod combo seems very stable. Pockets have to be thin to fit in thin surfaces. Thin molded plastic surfaces are subject to distortion when cooling. Pocket tops and bottoms have to be in precise parallel planes to work right and the rear must be open in order to slip the drive shaft off the coupler to service a servo. That is, if it is closed to assure rigidity, shaft removal is prevented. No disrepect intended, but is there something wrong with a builder having to do a little custom work making pockets? I swear I can make a beautiful set of 4 in 1/2 hour. The procedure is certainly well-documented under http://www.bmi.net/propt/rds/. It just ain't "rocket science".
