Default Landing Gear Reinforcement

I had an escapade 40 which lost its gear on a landiing, which i had to rebuild. i have decided to get another one and wanted to hear how people reinforced the gear, preefferably without tearing the entire bottom apart. any help is greatly appreciated. thanks
also, pictures would be very helpful if possible

A tried and true method is to epoxy in some tri stock on each end of the block against the fuselage sides. Another is to put a layer of 2 oz fiberglass on top of the block and run it up the sides of the fuselage. If you don't have either of those handy, a 1/2 inch wide piece of 1/4 plywood or basswood will accomplish the same thing to anchor the gear block to the plywood sides of the fuselage better. You don't want to make it too strong though. If the LG block can't break away a really hard landing on the gear is just going to rip out the next weakest thing which will be the bottom and sides of your fuselage.

Ripping out gear is for trainers... once you advance to an escapade.. that shouldn't be happening. What was the cause of the gear ripping out.
+1 for the tri-stock, easy quick and strong.

Mine was reinstalled with some triangle stock and epoxy. I have not had any issue's with it since. Good Luck, Dave

Oh how I wish my dewey had nylon bolts and would have ripped off instead of taking the bottom out of the plane. Had a rudder failure, which put it in the dirt in a semi controlled crash.

Looks like the gear bolt onto the bottom of the fuse. Just use nylon bolts. Maybe up size them a bit to 10-24 or so.

Some of the arfs I've owned had very inadequate gear support structure. The deficiencies include too soft of wood structure where the T-nuts pulled through the wood, poor glue bonding, inadequate glue surfaces and splitting of hardwood mounting blocks.

Having entered the hobby nearly forty years ago when there were no ARFs, there were few gear failures and few planes that were seriously damaged due to the gear structure being too strong. Sometimes the gear themselves suffered... but rarely did the plane suffer because of gear mounting that wasn't designed to fail. Thus... I don't think I buy into the idea of keeping the gear support where it will rip, but I speak in general terms. No doubt there are cases of serious damage done by gear that didn't collapse easily.

If I were to disposed towards forgivness mounting.... I'd use Edwin's suggestion to use nylon bolts.

I beef up the gear and firewall on every ARF. My preferred method for additional gear support is

1. remove the existing T-nuts
2. using 3/16" light ply bought in small packs at the craft stores and ripped 1" wide and given small drill holes up 1/8" along what will be the bottom inside edge
3. these strips are mounted vertically around the perimeter of the gear mounting box to add glue surface to the inside of fuselage
4. fit a 1/4 aircraft grade ply above the existing gear mount (this is given small drill holes into the edges all around)
5. drill from the bottom through the holes and replace T-nuts
6. use longer screws if needed and remount the gear

I've used both epoxy and gorilla glue and think both work fine. The small holes are important to act as glue nails.
