About this Plan

RCM Trainer (AKA RCM Advanced Trainer, AKA RCM Trainer 60). Radio control trainer model for .40 to .60 size engines. Wingspan 58-1/2 in, wing area 673 sq in.

Quote: "The RCM Advanced Trainer, designed by Don Dewey and Joe Bridi, can be built either from the kit from Bridi Hobby Enterprises, 23625 Pine-forest Lane, Harbor City, California 90710, or can be built from the construction notes in this chapter along with the full site plans available from R/C Modeler Magazine Plan Service, P.O. Box 487, Sierra Madre, California 91024. The price of the kit is $44.95 and the price of the plans are $3.00.

The Advanced Trainer is designed for the novice who has gained the necessary training experience on the Basic Trainer, or for the beginner who has an experienced instructor who will stick with him during the training phase.

The RCM Advanced Trainer has 672 square inches of wing area with an all-up flying weight of from 5-1/2 lb to 6-1/4 lbs. Although designed for a .40 to .61 cubic inch displacement engine, we strongly recommend the use of a K & B .40 or O.S. Max .40 RC engine for your training flights. Later, you will find that this aircraft will be capable of all the maneuvers in the AMA and FA1 pattern when a .61 engine is installed.

The photographs accompanying this article were taken by the RCM Staff building the Trainer from the highly prefabricated kit from Bridi Hobby Enterprises. The total assembly time, less covering and installation of radio, engine, and hardware is 0-10 hours. Following the instructions and photographs for building the Advanced Trainer from the kit, a reduced set of plans and instructions will be provided for those who wish to build from the plans available from R/C Modeler Magazine...

Update 12/07/2016: Added article thanks to davidterrell80. This is actually a chapter from the RCM-published Flight Training Course (FTC) (1st ed. 1972). The 'article' (chapter 9 in the FTC) is entitled 'RCM Advanced Trainer' and the 'Advanced' name is consistently used throughout. However, the plan is entitled 'RCM Trainer' which can cause confusion with RCM plan number 354, the RCM Trainer (oz6537) by HL Stroup.

Update 12/10/2018: Added PDFvector plan tracing and CAD files, thanks to AlanSinclair.

Hello Steve, The RCM trainer by Joe Bridi was once published in Flug in 1973 (a German magazine, predecessor of FMT) but was renamed to Donjo. My father built it for me in 1994 as my second plane but sometimes life has different plans. It never flew and after more than 20 years still waits on its maiden which REALLY should happen once. I attach a picture of my Donjo in a quite eclectic colour scheme [more pics 003, 004]. Remind: it was build in the '90s and the covering scheme was chosen by a '90s teenager ;)

Here are a couple of photos of the RCM Advanced Trainer I maidened yesterday [more pics 006, 007].

A couple more photos of an RCM Trainer 60, built from OZ plans and a short kit from Rob at www.balsaworkbench.com [main pic, 008]

Hello Steve and Mary, I've send you some photos some years ago of my RCM Trainer, and I stated then that it was constructed in 1994. However, it was constructed in 1999, as a small note in the plane revealed. But more importantly, it took the skies last summer [pics 009-012]. I converted from a .40 O.S. engine, to an electro setup. Motor SK3 4240, kv=620. 60A ESC and a 11x8 prop with 5S 3300 mAh LiPo. Here under you can find some more pictures and I made a small movie about
it too: https://youtu.be/CBspCXqMmsI
All the best,

Hello everyone, My name is Bob, and I’m building the Joe Bridi RCM Trainer oz 5306 in honor of my cousin Mike who recently passed away at the age of 83. Since it was his kit, I decided to take on this enormous task. The problem is that I’ve never constructed a balsa wood model plane before. I’ve looked at the pictures, and followed the kits plans, but I don’t know if I’m doing it correctly. I would appreciate if someone would give me a little direction, and guidance in order to complete this project, and get the plane up in the air in his memory Thank you. Regards, Bob Toboy

Bob, look up YouTube there is a wealth of information on that site.
John Green - 03/03/2021
Bob, I'd suggest you and start a build thread on RCGroups, maybe in the Balsa Builders forum - there are many forums on there. Lots of wise and helpful people on RCG, I think you'd get useful answers as you went along that way. But you'd need to start an account first and then get up to speed with using the forum, of course.

Also (thanks Jeff) be sure to download and read through the supplement article file from here which is good and very thorough (at 15 pages), with lots of pics showing the stages of the model being built.

Thanks, much guys... I appreciate the input. I’ll give it a try.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
