Hello pilots,
While the crap weather in upstate NY continues to keep me boxed up in the house it just keeps the Mad Modder in me busy...........
Been wanting to get some of my older FMS 1400 sized birds converted over with oleo struts to help their tired airframes from all the grass turf abuse they've seen over the years.
I have 3 in particular and all of them have aft swinging retracts.............F4U Olathe, F6F and P-40E (all have been discontinued)
In 2015 they all got the SmallPartsCNC side plates that I introduced to this forum and now to introduce an oleo strut that is well constructed and CHEAP for these birds.
Low n behold its a freekin HK part !! :Silly:

All three struts are the same length and the larger size wheels on them am gonna be using on the nose of my A6.
So the mod on the Corsair basically involves cutting the steel leg of the original strut to the appropriate length(approx. 25mm out from trunnion)
Then put a wheel collar of 7-8mm thickness with 4mm ID on the shaft first and tighten set screw.
Enlarge the axle hole on oleo to 4mm (5/32).
I use the stock Corsair wheel and bored the axle hole to 5mm to accept an aluminum 5mm x .45mm tube as a sleeve to allow the wheel to turn freely on the 4mm axle shaft without wobble.
Install the wheel to the oleo using this 4mm wheel axle shaft https://www.motionrc.com/products/fr...main-gear-axle
Enlarge the oleo strut shaft mounting hole to approx. 4mm by a depth of 18mm and install on the shaft and mark spots on shaft through set screw holes for flat spot grinding/filing purposes.
I demeled the flat spot and then installed the strut and tightened the set screws and lastly Foam Tac'd all set screws.
Use a 5mm x 40mm 1/16 thick birch ply plate that is glued (also did the little wood screw cause the hole was already there) to the numbered gear door and then that is glued to the trunnion ( I used Zap Goo versus Foam Tac for gluing this )
And lastly paint up the bare ply with white and that is it, had oleo on in less than 2 hrs. These are gonna work great on the other 2 birds in basically the same approach with slight different cut dimensions.
So for less than $50 in parts I can upgrade all three planes.........SWEET.
Here's the finished results of the oleo upgrade to my Olathe Corsair.
