Converting the Bronco type XXIII to RC

[redboat219]

Manfred I too would like to ask for some measurements particularly the rudder arms and control arms.

[MFR1964]

Hello Unterwasser,

Total height 72 mm, width 31 mm, used a papermold to follow the contours, which i transferred to the circuitboard.

Hi Manfred sorry for the delay, i need the measures for the rear frame (the oval-like part)

Thanks

[MFR1964]

Romel,

That would be the most logical item, since the batteryhatch is allready in use, i think i'm going to use the curved rearpart of the exhaust, the frontpart is placed under the tower, so releasing that, will give some problems.



I've opened up the rear half of the boat, just to see what room there will be ,the most front of the upper foampart has to be cutted in half, giving me room for the release mechanism, i'm going to build this in reverse, first the release mechanism and working back to the connection with the SD.

How about using the diesel exhaust housing for the retrieval bouy system?

Nice Manfred. Someday soon Ill paint mine as well.

[MFR1964]

Last week i played around with some paint, the hull is painted into it's two tone colour and there is some progress on the tower,



All basic colours are there, still have to make a mask for one specific sign which was placed on the tower, when finished i can place the nav lights and their glass windows.





Hull is also painted, for now i keep it basic, still have to tinker inside, next step will be, ripping out those pesty copper rods from the torpedo shutters, and replace them by carbon rods, thus eliminating the lubrication problem.

The brain is also coocking about the emergency buoye, which has to find it's place on the boat, in general i will follow the system i've build on the type 212, space is now my biggest problem, and it has to be build in such way that it will intergrade with my sliding SD.

Unterwasser,

I'm back in the cave, what measurements do you want to have from the rudder/diveplane support?


Manfred.

[MFR1964]

I don't have any plans, made all things on site, i did followed the general drawings from a book about the type XXIII, if you want to have exact measures, be patient, because i'm on travel, will return within a few weeks home, don't expect that She Who Must Be Obeyed has the code from the Skunkworks.

Manfred.

Hello Manfred, i'm starting my Type XXIII project and plan to use your "two sections joint". Do you have a plan or measures for the rudder/rear planes support?

[MFR1964]

Made today the third testrun, and boy oh boy, i need to make another one, still have issue's with the stabilising part, i've changed something and like David's one, i have a pitchdown problem when speeding up.
The launching of both torps went well, another one down on the bucketlist, as for the pitchdown issue, i have to recalibrate the boat when level, this evening i made a discovery which may be the source of all this fun.
When i put both halves together the SD is lifted up slightly, this is due to my instant connections for the float and rising stuff, when the SD is lifted the zero bubble point is gone, i'll put everything solid with some wooden wedges to get it level, preform the zero bubble trick, and have to make another run to see if this is the problem.
Another thing was noticed, when trimmed inside the bath she was perfect, on site she was higher in the water, i know this is due to trimming her in pure sweet water, the water at the pond contains a mixure of salt and sweet water, want to make several compensation weights to counteract this, still want to have her slighty positive.

She Who Must Be Obeyed documented this event again complete with the ugly and the bad, enjoy

Manfred.

[MFR1964]

That can be done, only be aware not make that bulkheads too heavy, there is not much room inside to place your foam to counter the weight, since you have to slide your SD in, there is only room at certain places to glue in your foam.
As for keeping together both hull parts at the radial split i would go the way i went by using magnets, the holes from the machinescrews are going to ware out after some times giving you unwanted results.

Manfred.

[redboat219]

Thinking of using machined plastic bulkheads then screw the hull halves unto the bulkheads.

[redboat219]

May need to reinforce the area where screws are as the plastic may develop stress fractures over time.

[MFR1964]

I've followed his build too, he made a much simpler version from the radial split, only borrowed my rudder/dive plane module design, from what i've understood he keeps his hull together with machine screws, another neat simple solution.
By unscrewing those he can gain access to the inside for removing his WTC.
