Hi Chris!

It seems the RCM Advanced Trainer is a tad different than the RCM trainer by Bridi. I am thinking the RCM Trainer is the Trainer 40???

Anyhow, it is obvious I am building the same bird you held in your hands in the pictures. Does it live up to the hype Joe says n the instructions? This is a fantastic trainer. I am very interrested in the silk and paint project of yours. At this moment we will be using Monokote. When my son comes of age, I have a feeling we'll be building another one and using a different covering method that will incorporate paint.

We also chose to stay old school and kept the rubber band approach.

You should have seen the look in my daughters eyes after we joined the two wing halves. Priceless!!! I have pics that show the wing is taller than she is. To her it must seem huge.

Brian,
It's a real good flying model. It is more of an advanced trainer, really. I remember some guys taking the dihedral out and flying them in Pattern as back-up ships.
Yes, mine is the RCM Trainer 40.

My RCM trainer is my test bed for different engines, the one in the pic's are a Rossi 65
I still have one NIB 60 kit and two NIB 40 kit's.

I call it a pattern trainer, it flies so good.

There were several variations of this design

Bridi himself had three different 60's differing mainly in wingspan by varying the spacing of the first rib bay at the root. Bridi often had slight variations of his designs with different names. The current Krafty 60 is the third design rudder with a shorter wing. Many contend the first design rudder that is forward of the elevator as pictured in the previous post was best?

RCM has two different 60's and the 40. Look at the dates on the plans. I think the first 60 was not actually in RCM itself but in a special edition.

Great Planes had a couple of Trainer 60 variations with one having a different rudder design. The original plans should still be available from Great Planes? The later 60 trainer had a flat bottom wing and that is not what you want. The desirable one had a semi symmetrical airfoil.

I think there were some variation in the height of the wing above the thrust line in some of these.

They all fly good but some contend that their favorite variation is better than the others

Some of the 60's were pretty good pattern ships

Ours is the pl-476.

They all look pretty much alike, I'd be confused.

I am thinking the main differences I have seen in this thread are personal choice touches. For instance, the wing tips on hogflyer's airplane, and the center wingtip bracing on martenson's bird. Wonderful airplanes, btw.

Martenson-

I have pm'd you.

I recently finished a 40 trainer that I had sitting around for years. It has foam core wings and was called a T-40 by Ritch's Imports. Here are some pics. In the past I have also built the Great Planes versions of the 40 and 60.

Sorry for the dupe picture. I tried to edit it out, but no workee. Failed to mention I used Flat finish Monokote. It went on like the old monokote of the past. Wish they had red and white in the lineup of flat colors.

Thanks! (I'm his daughter)

Speaking of Bridi trainers has anyone seen or heard of the T 10? This was a little 10 sized trainer with a flat bottomed airfoil. I had one many years ago and it sure flew well. I would love to get my hands on some plans or three views and build another for one of my old Enya 09's.

Brian,
I owe you some pics of dad's RCM Trainer. I'll get down to HB tomorrow. They are on their winter move to FL now, so it'll be my last chance for a while.

Peter,
Sounds vaguely familiar. I never went for the smaller ships but I seem to remember them. Sorry, have no info on them.

Here is the second RCM Trainer from dad's garage. He covered this with silk (dyed yellow on the wing and stab) about 1977 and I just at the end of 2010 painted the fuse and rudder, assembled the innards and it's aff and running. He's using a Magnum 46 and an Airtronics SD-10. The landing gear, motor mount and some servos are from the red one in an earlier post.
This is an RCM Trainer 40 with the 52 inch span and fully symetrical airfoil.

Now that is an airplane.

Thank you Chris!

I am hoping that I will be building at least one more of these with my son in the next couple of years. It is a great airplane. I'd like to finish it with either silk or koveral and shoot it with paint.

Thanks for the pictures.

Bridi RCM Trainer 40- 58.5 inch wingspan- Aileron servo question.....

I cannot determine how the aileron servo is supposed to mount. I have the original plans but they are not very clear, at least to me. Could anyone provide a picture of how the single aileron servo mounts to the underside of the wing? I would really appreciate it. Thanks.

Inset my servo tray into the wing and trimmed around tray. Works great.

Good job,
It's that east. Mine were actually 1/8th ply on top of the sheeting of the wing, and the center hollowed out. The fuselage is so deep, no problem with clearance with the other servos.

Thanks. Here is a picture of the completed servo installation. (Same two pictures for some reason)

Swimmer, looks good. I would recomend some glass cloth on the center section, top and bottom. I can see a faint line and you may already have the cloth on and the photo lighting blends it in. I always like to fill in the cloth and along the edges with lightweight spackle filler. Then you can feather sand it to disappear under the covering.

Notice the geometry on the linkage that enables differential aileron throw. Very little down and a lot of up aileron. This prevents adverse yaw

swimmer316

This will be my first project to cover. Plan to use Ultracote.

Boy, this thread is bringing back memories! My first attempt at building an RC airplane was an RCM Trainer .60 ca. 1978 when I was 13. I messed up the wing, and put it aside for a few years, in the meantime, building/learning to fly a Goldberg Sr. Falcon and an Ugly Stik. One day, I was at the LHS, and lo and behold, they had a wing kit for the RCM Trainer 60 for $15 (those were the days!), so I picked it up. I built the wing (correctly! no dihedral), repaired some of my mistakes on the fuse also making it a taildragger, and flew it for a few years with a K&B .61. Great airplane!

My friend had the .40 sized one that was crashed and repaired so many times that it had more polyester resin and cloth in it than balsa when it finally met it's ultimiate demise due to a reversed aileron servo.

Those old Bridi kits were absolutely gorgeous. The machine cut parts fit as well as any laser cut kit today. They were also pre sanded, so you took them out of the box and started gluing! Compared with my die smashed Sr. Falcon, it was heaven!
