So, moments ago, I was in process of removing the new Fox 35 50th Anniversary engine from my Twister that I had purchased this past summer. I was just doing so, as I was going to break in the engine on the bench in the spring, and would be lighter to hang from the ceiling without the added weight. So, after removing the engine, I went to stand up the plane and I saw where the engine was bolted through the 1/8" doublers. That is all it was bolted to! There was NO engine bearers installed into the airplane. So, with that now said, what about the rest of the airplane? I am now thinking of cutting into the wing just to see if he even bolted the bellcrank down, or did more than one wrap of wire on the leadouts. I am just sick right now knowing this. I paid top dollar for this thinking it was all good to go, now I am having my doubts! Damn, how do I know if he even glued the wing together? Anyways, I just wanted to show you all what I just found and now I have something to try to fix up and ponder!

You should also remove the landing gear and see if there is anything in the fuselage to keep the gear aligned.  Sig uses a brass tube but something stronger would be better. If the landing gear wire is just stuck into the doubler that will be another problem.  You could just pull test the airplane to see if the bellcrank and leadouts hold up. 

Ok. So I just looked, the gear does indeed have a brass tube installed, and appears to be epoxied in place. I also took 30 lbs of freeweights and tied them together, then tied them to the leadouts. Nothing moved, cracked, or anything. So, it looks like that part is good, with the only problem being the engine bearers. I am glad I was able to spot this before flying as it probably would have ended up in a disaster, and I did not get any plans with the plane either. So, I guess I will source out some epoxy and some spruce then install myself some engine bearers! It now sounds like I am going to be having some fun!

    Makes one wonder whether the builder knew what he was doing at all, or just trying to screw someone.

I had honestly thought for sure that the gentleman knew what he was doing. He was a certified AME here in Canada, owned a couple of planes himself, and maintained them himself. I do not honestly think that he was there trying to screw someone, he was a genuine person in my opinion, but had absolutely zero experience or knowledge with control line. But, now for the rest of this story...

The person originally had a huge 'lot' of model airplane stuff for sale and was reluctant to split the Twister for me. Included were 2 trainers, 1 I believe was an ARF, a couple of planes mostly built ready for covering, and the Holy Grail, a 1/4 scale Cub with floats and wheels! Nothing had been run or started, with the exception of 1 engine. All radio gear was older FM stuff. It looks like I have to tell my buddy at work about what I had found with my Twister, as he bought the rest of the stuff! I really want him to check over that Cub, cause it is really nice, looking...

It is just a good thing that you did not fill the tank, prime the engine and start it up while still on the model. Might have been some serious issues and potential injury.

 Wow. Wow. Uh, WOW.

 I can't believe something as obvious as this could ever be missed. This is something that should have been discovered WAY before the model ever got to the flying field. Built by oneself or purchased from another party, absolutely no excuses either way.

30 min is fine.

Thank you. I will then use my 30 minute with a couple of 'pins' through it as well as clamped as per Dans recommendation. I just want it to be fixed right the first time.

The mounting bolts for the IC engine should help hold the glued joint also.

Yeah, those are getting replaced too. Brass, undersized, and on the plane with a simple brass acorn nut. No washers or lock washers. He did, however,  get the right length!

Got the motor mount blocks installed. Mixed up the epoxy and put a bunch in and on each area, upper and lower. I then pushed them in as far as I could go, then proceeded to use my smaller mallet to put them in. Well, about 2 inches remaining, the head flew off my small mallet, just missing my face. So, quickly I throw the handle on my workbench and go to grab my small hammer from the drawer. I get it, start to put the top mounting block in, and get it all the way in. Put down the hammer, clean up some of the epoxy that had oozed out. Go to grab the hammer to repeat to the lower one. As I reposition my hand on the hammer handle, it feels funny, and sticky.... Remember me putting the mallet handle down. Well, I kinda lied. I kinda threw it on the bench, in turn knocking my epoxy all over. Remember me putting down my hammer? Yep, right in the epoxy I did not see! Anyways, pound in the lower beam now till flush, clean up the outside of the plane and evaluate. Place some of the remaining epoxy in the little cracks and gaps I saw. I then followed up by wrapping the nose with waxed paper and clamping very securely and am now waiting for it to dry. Anyways, it is now fixed, and I will mount my Fox 35 without muffler, and check the balance after the repairs and required mods that were mentioned earlier that I did not yet do. Anyways, thank you all for the help, tips, and advice along the way.

Bet you didn't realize you were buying an ARF. 

Hey Chancey,
This will be hilarious some day.
Make sure nothing else in there needs a fuel proofing coat of epoxy too.
Also, the wing looks pretty sharp on the LE. I think I sent you a template for that shape? If not, let me know and I will. If it's Monokote and you're careful, you can strip it for sanding without botching the whole wing covering. If he left you a diamond shaped LE, it will fly like crap.
