| Subject: | Yak 52 updated wing spar is a must? |
Still looking for a plane , see some Yak 52s and prices are quite a bit lower than
CJ6, Would you buy a Yak 52 without the updated wing spar?
Has there been cases of wing separation?
How many hrs are too many hrs on this kind of engines?
Is 500hrs a lot?

All the 52's in the US that I am aware have the wing mod. I don't
personally know of any failures, but they obviously had a reason for issuing
the service bulletin. I would not want to fly any airplane that did not
have all AD's and service bulletins complied with.
Most people agree that 1200 hour is not an unreasonable amount of time on
the engine. As long as it sounds good, has good compression, and not making
metal, I would have no reservations about flying a 1200 hour engine.

One Yak 52 I was looking at does not has the wing upgrade.
The owner said it was overkill.
I guess I wont be buying that one.

There has never been a wing failure in a Yak 52. EVER! Including before SBs 59
and 60 were installed and the airplane was then de-rated to +5 -3Gs without the
2 SBs.
500 hours on an M14 is minimal. Unless the engine is installed on an unlimited
aerobatic aircraft like a Sukhoi 26 etc. where they are operated at only two speeds....wide
open throttle and idle.

You are going to find a lot guys on this list who favor the CJ over Yak and vice-versa.
I have a lot of backseat time in Yaks as a formation check pilot and
ferried one or two. Not much acro in them. I have over 2,000 hours in CJ-6s.
A lot of acro time compared to the Yak. I've worked on both aircraft too.
Maintenance wise the CJ-6 is easier to work on. In the Yak things are in tight
places and between the firewall and engine is not much room to work. Systems
are much the same and a lot of parts are interchangeable. The CJ does not an
inverted oil/fuel system thus less maintenance there. It is easier to add long
range tanks too and little extras like autopilots. Replacing a run out HS6a
engine with a M-14p is very easy and many have done so which ups their valve
at least the price of the engine.
The CJ does all the same acro maneuver as the Yak - just not as snappy or quick
and often needs to be flown through them. In spins, the Yak requires training
with real Yak instructor. The CJ is a bit more forgiving but still need a good
understanding. Any verticle maneuvers are very challenging with the small
engines and unless the horizontal stab has been re-enforced, tail slides are
a no-no.
On cross-country flights, the CJ is far and away more comfortable and cheaper compared
to the Yak. In formations, both aircraft are a joy. And the comradeship
is more than just the pride in one's own airplane. Now the only Yak I ever
considered owning was a Yak-50. BUT you give up having an extra seat. Otherwise,
you can tell am a CJ guy.
23 years ago when trying to make my decision between the two, I flew both aircraft.
First the Yak then the CJ-6. I suggest you do the same if you can. No
matter which you pick at least you'll know which one is the one for you. THEN
go look for the cheapest one you can afford.

Not true Jim. There are several 52s that were imported in the mid 90s that did
not have the so-called heavy spar. (SBs 59 & 60). Carl Hays, when his shop was
in San Diego, imported some of them.

If you're looking for a roomy, easy/pleasure to fly (no vises), capable of
elegant acro Warbird, the CJ6 is your ticket. If this is an attractive
concept for you, then you'd appreciate the extra power and performance a CJ6
with the BIG Engine (M14-P) coupled with a 3 bladed propeller can offer...
You may want to check out my Big Engine CJ-6A (Sax Machine) listing on
barnstormers.com , you can find it by entering "CJ-6A" on the search tab or
under Warbirds/CJ6 category - once you see the listing, make sure to also
click on 'Display Specs Page' for the long list of other upgrades on this
incredible CJ6...

Ha - 1999 all over again [Rolling Eyes]
CJ6 guys say buy CJ6s.
Yak guys say buy whatever you want.
Fly both and decide.
Me, if I have to maintain a radial... one will speak to you more than the other.

Its okay if you restrict your flying to 4 Gs or less.

How reliable are these radial engines compared to a GA engine from Lycoming or
Continental?
I know they take oil, but are they pretty reliable? If you have the discipline
to turn the prop before starting, check compresions at annual, and fly it often?

There have been examples of radial engines running for minutes (eight, if I remember
well) when all the oil was already out.
They can run for a long time when one or even two cylinders are completely out
(I agree, it depends).
I haven't seen any statistics but I see no reason why a radial should be less reliable
than a standard GA engine.
If you do the proper maintenance and take all the necessary precautions before
starting.
Only my 2 cents,
