The thing I like about using the ADF for ballast is that is quickly and
easily removable--never been a fan of scuba bottles, Cornelius pumps, lead
etc. that are fixed dead weight. Besides, propping is easy and seldom
required, barring brain fade of some sort.
I've always been concerned about the polar moment of inertia of additional
fuel tanks. Not only do you have a very real possibility (likelihood?) of
going over max gross wt, it sounds like Drew's tank setup allows uncommanded
fuel transfer between tanks. Yak-52W's and TW's have a mickey mouse setup
requiring transfer from the aux tanks to main tanks using pumps. Venting is
suspect at best and uncommanded fuel transfer can occur through the pumps,
even when they're not running. Plus the pumps will happily run all day and
pump the fuel overboard--no auto shutoffs--so you have to continuously
monitor the fuel gages, which are not very reliable, even when they work.
If the pumps fail you may land short with unusable fuel in the tanks. Not a
happy thought. Aerobatics are not allowed with fuel in the aux tanks,
regardless of weight. Can be a problem if fuel transfers occur without
notifying the pilot!
Regarding 7-point belts in Yak-52's: new W's and TW's attach them to
fuselage frame brackets as I recall, not to the seat a la CJ. I like
7-point belts for acro, but they're not very comfy, especially for cruising.
I'd mount the ratcheting belt aft, so you can put the tightest belt against
your hips, but then, you probably already know that.

--> Yak-List message posted by: "Tom Johnson" <tjohnson@cannonaviation.com>
Does anyone have access to detailed historical or engineering data about the M14P
and/or any of its predecessors?
Looking for as much technical and engineering data that might be available.
I've seen most of what is on the web, was hoping maybe there was more of the history
of the design out there somewhere.
. . in english . . .
I'd like to put an article into the Aircraft Engine Historical Society website (www.enginehistory.org).
Please reply off-list and I'll summarize to the list when done.

I have it in my CJ, a gift from a friend. If my memory serves me right, the
second was attached to the seat attach points. I am away from home for the
next 2 weeks, but will take a picture for you on my return.
