There is only one version but you can get some optional accessories if you wish. I just received mine and am happy to say that it is a very professionaly built unit. Bill has been great with communication and assistance.

details can be found at www.troybuiltmodels.com

Kind regards
Craig

graham,

the Lancaster is a 4 engine beast.... man you are tha man!  Just as a not you will need two synchs for that, there are notes on how to wire it up for 4 engine synching....  You'll need 2 glow driver sets too...  Bill will be able to tell you though, just make sure to mention that you are synching 4 engines..

Btw, I'm in the process of building the Top Flite DC-3. Maybe one day I'll get my hands on B-17 plan and build one...

I've been looking at Russin aviation examples and i thought this was a cool video  http://www.youtube.com/watch?v=DVqilOx6lNQ 
Some of the discussions are interesting

Status: offline 		Ok.....So I have the Quadsync installed in my B-17G. I didnt want each of the drivers in the nacelles so they are all lined up in the center of the wing under the fusalage next to the Quadsync. I was kind worried about running too small of wire two the glow drivers so I ran some pretty heavy copper strand stuff I had handy from my surround sound speakers to the glow plugs. It is about 18g.

I am also concerned about the size of the switch needed and how to charge the battery back up. I read in here somwhere you can burn up the drivers while charging with a programable charger if it is connected to the drivers. I made a 5 sub C, NiCad, 1.2V, 8500mAh battery with a Deans plug attached. I also bought a Deans plug power disconnect. It has a heavy Deans plug/key you put in to power up.


So the questions I have are the following.

1. How large of wire did I need to run to:

a. the three feet to the outer drivers?
b. the two feet to the inner drivers?
c. the two feet from the battery to all four drivers?


2. How heavy does the switch need to be?

3. How many amp/milliamps will four glow plugs pull?

4. How long will the battery last at full charge?

Thanks

SR

Status: offline 		BTW...Why is this thread called "Eletronic engine syncronizer**SUPPORT **"? Changing the name of the thread to add Twinsync/Quadsync and going from Eletronic to Electronic/Digital would make it easier to find. I think the original poster can make changes.

If I understand it well ... [>:]

you have 4 Stroke engines ( looking they are Saitos ...) SO let's count 4 amps per Glow plug ...

from that, you should use some .75 sq mm wire as a minimum not to reduce too much the voltage ( think to the voltage survey Bill placed ... )

no need to use different wire gauges ...

personnaly I would use 1 sq mm ( easier to find Xtra flexible wire for measuring purpose ) from the batt to the glow modules and to the Glow Plugs.

resistance will be .021 Ohms per meter ( 3 ft ) of cable ...

so outer glows voltage drop will be ... 2 times * .021 ohms /3 * (2+3) feet * 4 amps = .28 volts ... becomes significant !

anyway thanks to bill for his very prompt service ,many emails and also a telephone call with advice on my quad sync queries... if only other things in life went so well !

I'm just finishing my Ziroli P-38 and I'm wondering how you are mounting the pickup on the engines? I'm using two DA-50s.

Status: offline 		hi bud ....regarding your query...

Im not sure about the da 50s ....but for general info

on my asm lancaster with 4 x os 72 alphas i had the same issue as you...not very keen on mounting sensors on ply / pc board etc due to distance from engine lugs etc so i came up with this which so far has not caused any issues...

position sensor wires nice flat and even, with pick up side of detector, dont think it makes a diffrence which side.....

place some cling film or similar on a flat surface, place sensor with detection side upwards, with cables nice and neat, pour thick cyano over sensor and a couple of mm of cable, then push firmly down with a thin peice of balsa, 2-3mm is ideal and activate the cyano if required.

peel the cling film off of the sensor and with a dremmel trim the balsa / cyano close to the contour of the sensor / lead.

turn sensor over and as the surface of cyano should be flat, cyano a thin piece of THIN ply to this side, and again dremmel to contour.

cyano THIN balsa to the ply and again trim to contour.

finally on the detector face gently sand away the first balsa fixed until cyano / trace balsa / sensor is just visible, this will give a dead flat face, supported with ply and balsa....

Bore the prop driver to to take the diametric magnets (obliously as close to circumfrence of driver as possible)

I then placed the detector over the magnet and tie wraped it to the crank case above the front bearing. it is up to you whether you, as i did run some thin cyano into the surface balsa to harden up a bit or not, The object of the balsa above the ply is to enable some firm grip from the tie wrap as the balsa will compress. i for security ran some cyano around the tie wrap and the end result is 1mm clearance above prop driver, a very short firm mount for the sensor and minimum vibration.

i have tested this method in the air when i was running in the engines in my great planes Shoestring and after 14 flights no adverse problems were encountered.... i have yet to balance my props on my lancaster so i will take a pic for you of finished install .......

my lanc now complete and test flight will be 17th april, mean time i have a few weekends doing pre flight tests / setups etc

regards

graham
