Does anyone know if the 601 XL and the 701 use the same spring gear?  I've 

noticed ACS has offers the 701 gear.

If you want to order this part from some supplier, why not order it from ZAC?

They are not the same.

701 (factory) is 3/4 x 3-1/4 x 82" 2024

	Grove uses 7/8 x 3-1/4

601 (factory) is 3/4 x 7-3/4 x 96-7/8" 6061

So does Grove. They are pricey, but they also offer gun-drilled brake 

lines:  http://groveaircraft.com/landing_gear.html

Grove offers the spring gear for the 601..and it IS pricey....but it's about 

the same money as the one from ZAC.  The BIG difference is the weight.  The 

Grove gear is almost 15 pounds lighter.  That's a significant amount.

Dad,



I see ACS has composite spring gear available for the

601 and 701. I don't see how a two piece setup would

work though. Anybody used these yet?

The composite gear offered at Aircraft Spruce looks

remarkably similar to the gear that Chip Erwin builds

at CAW.  The price is awfully good, and the weight

savings is significant.  I did some research over a

year ago and reported back to the list.  Check the

archives for Grove numbers.  I think the Grove gear

with gun drilled brake lines and wheels and brakes ran

about $1600.  If I wasn't already done with the gear,

I would look seriously into the composite from ACS.

601XL Thread Friends



I have just ordered the composite legs (mandatory in UK) from CZAW and

these cost 867 USD including shipping and tax (19%) which is just for

the legs with no fittings whatsoever.



I would like to use the Grove axles, wheels and brakes which look very

good and have roller bearings, rather than the CZAW design which are

20mm dia axles and I believe Matco wheels with ball bearings.



Has anyone using composite legs had experience with Grove wheels as

there looks to be a conflict with the brake cylinder components when

using the ali gear and I would be very loathe to start cutting away the

composite material.



Answers on one side of the paper only!!!



Many thanks in advance.

Malcolm,



First let me apologize for answering a question with a 

question.  Alas, I don't have any answers on this one.



My question is:  How does changing from a heavy piece of metal to a 

(presumably) lighter piece of fiberglass impact the weight and 

balance of the airplane?  Is it necessary to position the landing 

gear in a different location?



Also, do you know why you must use the composite gear in the UK?



Thanks,



Paul

Firstly all homebuilt aircraft in the UK must be to an approved design

by the Popular Flying Association (PFA) who act for the Civil Aviation

Authority (CAA) and will ultimately issue a Permit to Fly.



No changes to the certified design can be made without PFA approval and

the design certified by the PFA is for the CH601XL model is with CZAW

modifications which includes the composite main gear.



This gear is two composite legs housed in 4130n steel chambers and with

modified part 6B11-4; there are also small changes to the transverse

gear channel.



I suspect the change in weight is close to the mid-range of the c of g

but obviously no problems in this direction as aircraft certified and

flying.



Sorry if this is a bit long winded!



Malcolm

It is even more restrictive than the message below indicates.  After plane 

is finished, it is inspected by the PFA, and then you must pay a PFA test 

pilot to do the test flying it before you can begin to fly it.  Any 

structural repairs must be approved by the PFA. There are probably more, but 

we are blessed (or cursed) with less restrictive regulations.

If it's anything like the CZAW gear, which is two curved legs, you get=

 two saddles/clamps, sorta like Zenith's, that go at the outer edge of=

 the fuselage. The gear leg extends inboard for almost a foot from the=

 saddle/clamp, and at the inboard end, you can use a steel plate insid=

e the floorboard to spread the load, with two bolts drilled through th=

e inner end, and suitably washered. The outcome is that you get an up-=

force at the saddle, with a down-force at the plates.  I used a consid=

erably larger plate than the CZAW plans called for. The tread on the C=

ZAW is approximately five and three-quarters feet wide. Somewhat narro=

wer than ZAC's. It's about the width of a Sonex, but a longer wheelbas=
