I have the Calmato as well,

By looking, I can see your problem. I would not use epoxy for this application. You may be better off trimming the new gear or trying to find the replacement gear.

Also try removing the servos to access the blind nuts from the top of the fuse. If nothing else, try some 'butterfly' nuts, (the smallest you can find), and use them in conjunction with epoxy to secure the new gear. Remember to re-balance if you add new hardware.

As far as everything you have tried going wrong, I agree!! That is the nature of any new skill. I needed a lot of help learning to drive a car, especially in California. I needed a lot of help with trig, calculus and computers too. (Probably less help than I need in RC planes).

I sense discouragement. Learn from these experiences, you have a lifetime to enjoy this hobby....take your time. I am new to this as well. Heck, I can't even keep the plane where I want it for landings. I am getting frustrated too. But after I take a few minutes to watch an accomplished RC pilot do some really good flying, I can see the light at the end of the tunnel again.

Building and re-building are fun for me. I have been building models for years.....long before I ever flew one. Just try to be patient.

Good Luck,
