Okay I know quite a few people have had this problem, and the fix seems to be putting bolts and nylon lock nuts through on the landing gear. Can anyone show me a couple pictures or explain how you do this as it doesn't look like there is any area for the nut to do it on a stock raptor.

This is space for a nut, in the little opening on top of the landing gear bolt pad. It will just barely hold the nut, becuase the nut is a bit bigger than the hole.

Make sure that you also get long enough bolts. I don't recall the length of mine but they are just long enough barely.

My suggestion is just go for it. I think 3mm bolts is the size I used. I am at work so I can't check.

Good luck.

a flying buddy of mine dumped his Rap last week and cracked both
frame legs.

he didn't use my suggestion to use either nylon screws or just
small plastic wire ties to connect the landing gear and canopy
mount studs.

I have a R30v1 that was purchased in early 1999 and it's been
crashed god knows how many times.

I've only replaced 1 side frame once last year.

Have you tried slow cyano on the threads before putting the screw in? This should stop it from turning loose. If the frame is stripped then a bigger self tap screw should also work fine.

3x25mm's are just a tad long. You may want to grind a milli or 2 off them, or add a couple extra flat washers underneath. Nuts fit on top like they were meant to be there -- I think that was an intentional design decision.

Drill the frame holes with a 1/8" bit and they slip right in.

I just use 3x20mm bolts. No nut needed. They have been holding for over 20 gallons.

Having done this for the last 3 years or so, and finding it a very satisfactory solution, might I suggest the following?

Choose 3mm cap head bolts, and make sure they're the correct length to go through landing strut, carbon baseplate (if you use one), frame and finally nyloc nut with 1-2mm to spare. You can either cut a bolt to length, or use washers under the head of the bolt. Bolt length is not so critical for the front, but the rear gap for the nut is not very deep, and you don't want to come near the tank.

Screw the bolt through all your layers, install nut, and tighten up. (The bolt thread will strip the frame plastic to the correct size, but if you're fussy, drill the frame hole out to 3mm.) For the front use spanner, for the rear rely on the grip of the surrounding plastic to hold the nut. If it starts spinning, use needle-nose pliers to grip the nut from behind.

Once you're happy with the result, ensure the rear nyloc and plastic are well de-greased, and place enough JB Weld to fill the well around the nut, but leave the top of the nut free. When well cured, you'll find you can install and remove the rear cap head bolts with ease, without the nut spinning. The front still needs a spanner, but that's easy.

The JB Weld is a great idea. I'm stealing it.
