Retractable Dive Planes

[themongoose_OLD]

Hey gang, I tried a search and came up with very little. One specific question I had was which issue of the subCommittee has the instructns on how to build a set of RDPs? Then, in general, are there any websites out there that you know of with good pictures or instructions/tips & tricks? I looked at the engel site and the robbe site but there's not much detail there.

Thanx

Which sub are you modeling?

Which sub are you modeling? The reason I ask is that retracts for a US WW II fleet boat are quite different than a say a soviet Typhoon.

Also, I'm currently doing a refit on my 1/48 fleetboat, and working it up as a couple of how-to articles for upcoming issues of The Report. There will be lots of pictures and diagrams concerning the retract system (and the rest of the boat)

Cool. I'll have to look

Cool. I'll have to look for your articles. I'm trying to finih mine before the regatta this july. if there's anything you can share with me aghead of time I'd appreciate it. Thanks for th einfo on the SCR. I sent Don a request for it this evening. Chris.

Chris,

I'm building an Engel fleet

Chris,

I'm building an Engel fleet boat and have their bow plane retracts. Richard Pflanzer is also building one and also has the retracts. They are fairly expensive, but are engineering marvels. Mine are not yet installed nor working, but they look good. Engel uses a motor to run a gear train via a toothed belt that further turns shafts that cause the planes to rig in or out. Really ingenious. The planes are interlocked with the pitch servo so that the planes must be level before the rigging motor is energized. The system has three relays, motor gearbox, plane gearbox and switches. If you wish further info, contact me direct.

Jim,
How hard would that be

Jim,
How hard would that be to convert over to a non engel setup? One of the pictures on thier site showed some sort of plug board.

This is awesome. Looks simple

This is awesome. Looks simple enough to build. I'll give it a try! Thanks Tim

ok, $20 and some old

ok, $20 and some old parts from my RC car later and I have a layout for my retractable dive planes!!!! I thought the sketch Tim S put up looked doable. Can't [post a pic yet apparently until someone turns on my membership on here I guess. I'll post it on my webpage on this site. I used a driveshaft, ball and sockets, and a few plastic swing arms from my rc car in conjunction with 2 brass rods to cobble this together. I'll post an update when the kids are better and I have time to work on it more (2 out of 4 down with a virus right now).

Further info on the Engel

Further info on the Engel Bow plane retracts. The mechanism runs via simple on-off switches that feed into Engel's relay board. What happens is the relays control the rotation of the motor that drives the retract mechanism. The motor spins 17 revolutions and shuts itself off when the planes are either fully rigged out or in. A normal servo controls the plane pitch. It is interlocked via a switch to ensure that the planes are horizontal before they will rig in. If the plane are out had have a pich, the motor will not engage to start retracting them.

A lot of thought and engineering went into the mechanism.
