    Engel type VII/c first impressions review

    I took the plunge and purchased the Engel type VII/c U-boat kit and thought I would share my thoughts on this model.

    It arrived in two huge boxes very quickly after I placed my order. It was extremely well packed and my dealings with Engel have been fantastic. They always respond to e-mails very quickly and are very concerned with customer satisfaction.

    The hull is molded in GRP including the deck and comes in two sections. The detail on the hull is astonishing, I can't believe anybody would be dissapointed in the level of detail.
    The conning tower floor is photo etch but every other slot and limber hole will have to be cut by dremel and file. This is a huge job that may put some people off when compared to the photo-etched decks of other u-boat kits.

    This kit is very complete including many pre-fab assembelies including pre built brass railing sections. The stern plane guards rear skeg and prop shaft bushings is a pre-built cast bronze unit. The deck gun and AA gun are resin kits. The conning tower itself is resin (also very detailed) and there are three resin hatches that give access along the length of the hull.

    The pressure hull WTC is a very clever bit of engineering, but it is very complicated and takes a lot of work and skill to assemble. At the front is a rotating bayonet locking system with rotating contacts for five servos. There are also 4 torpedo tubes marked on the bow cap of the WTC, I suspect Engel have plans to add a torpedo function kit in the future.

    I did discover several errors in the full size plans and drawings book, mostly incorrect part numbers. The kit comes with a CD full of build pictures that is very helpfull. There are some written instructions but much of the work is done by studying the plans, drawings and pictures (which i like).

    The Engel diving system of using two piston tanks complete with proportional control and pressure switches offers and unbeatable level of depth control, although I should reserve my comments on its seaworthiness until its maiden voyage.

    Overall this is a very nice kit and well worth its expensive price tag. But it is not the almost ready to run model that some might be expecting, In fact I would say it is at least as much work if not more than building a comparable size model from a hull and semi pre-built gas WTC.

      Hi Schmitty - Sounds great.

      Hi Schmitty - Sounds great. I hope you will take photos as you build it and share them with us!

          I will consider writing an article, I will definetley take pictures as I go. I did some more work last night on the stern section. The Rudder and planes installation is quite complex and requires the builder to make pieces from "scrap" as well as soldering and drilling your own bellcranks and linkages. Like I said before this is not an ARR kit, But I am definetly enjoying the build.

              Yes, It is coming along

              Yes, It is coming along nicely (although slowly). I'm having trouble getting a radio system that will work well with it though. The area provided for the reciever is tiny and none of the recievers I have will fit. I also ran into a problem with the speed control I was going to use (pro boat) It doesn't deliver enough current to the BEC to run the rest of the boat.

              I am not happy with the control rods provided with the kit. The rudder and Stern planes servos have long control rods that have to make a couple turns and they are super stiff causing a lot of friction.

              The radio most suited is the Robbe F-14 but the included reciever does not fit in the space, The kit recommends using two speed controls for independant motor control but this seems unnecesarry in a U-boat to me (based on past experience) Strangely the kit recommends only using one channel for both bow and stern planes.

                It would be nice to see some pictures as this build progresses. Dual speed controls will assist in turn radius reduction. On my Engel Lafayete, the receiver did not fit either, so I placed it where the rec. batteries went and had a new receiver pack made to fit. I would recommend you do not try to run this boat with BEC due to the draw on the main motors and ballast tank motors.

                  Have you purchased your radio yet?

                  If not take a look at Multiplex (good sets).

                  This receiver should fit all but the smallest of boats-



                  Twin ESC's is a nice addition on a Type VII, especially when sailing in a small pond.

                  Mtroniks do a special subamrine ESC with a beefier BEC.

                    An alternative is to use a separate switching BEC of greater capacity like http://www.medusaproducts.com/Other/...-BEC-45035.htm

                      Thanks for all the advice.

                      [color=#000000]Thanks for all the advice. I do understand the logic in using two speed controls to decrease the turning circle by reducing power to the inside motor but my experience with the type VII has shown that the benefit is lost due to the fact that the inside rudder no longer has the propwash acting directly on it, Overall effect]

                        Check with Multiplex, but I think that the receiver will work with other radio TX's too.

                        Are you really that tight for space? This is a big boat after all, I'd have thought there was plenty of room, even taking into account twin piston tanks.

                        Perhaps you could post some images or drawings with some meaningful dimensions. After all, Futaba recievers, whilst not being the most compact available, certainly aren't gigantic.

                        Have you practical experience of poor turning with a Type VII with twin prop set-up?

                        Some small toy subs use this method of control exclusively, and they turn on a dime.

                        Graupner make a nice range of transmitters that are very similar in features to the Robbe/Futaba models. However they have better displays, and are easier to program. Not sure if you can get them in 75mhz, but worth investigating.

                        I'd have though a 2ghz set would have a very reduced range over the more humble 75mhz sets.

                          It appears to me that Engel has designed this boat using the F-14/F-18 series radios in mind. The new "TMAX" dive system would be simple to operate using an F-14 radio WITH additional modules. Me thinks it is all about marketing strategy. I would tend to agree that there would be ample space for radio gear, but without seeing pictures or a breakdown of the instructions, I am speculating.

                            You can mount the the

                            You can mount the the RX on the platform next to the motor of the piston tank, or if you are using 1 ESC, in the place where the second ESC would go. Additionally you can mount it vertically right up front on the end of the techrack, just behind the front end of the WTC.



                            You don't need to have 3 channels for the diving system if you don't want to, and already have a radio. It will operate off 1,2 or the full 3. If your buing a new radio for it, I would reccommend you get the F14 on 75mhz. You don't need any extra modules, just 2 sliders and a switch. Shipsnthings sell it with the sliders. Yes post some pics

                              The front sounds good, from a point of view of getting it well away from the motor, but it will mean rather long runs for the servos, and other connections to the receiver.

                              This may mean fitting booster circuits, or at least fitting some form of extra suppression on the leads themselves.

                              If you fit it next to the piston tank motor, and end up with interference, try wrapping the RX in some aluminium (baking) foil. This will screen it quite effectively from stray electromagnetic radiation.

                              Suck it and see.

                              Whatever, from that photo it looks like you have plenty of room for all the gubbins.

                              Markus Rieger/Dieter Meyer PistonTank controllers are much smaller than the engel control board, and would only require two channels for full proportional control.

                              They're about a $100 each though.
