RE: Removing cam bearing from a YS DZ 160 Crankcase
Thanks Adrian and Dave, Finally got the little sucker out geez what a struggle. I have certainly learnt a lesson never to leave a perfectly running YS engine in a model for an extended period- in my case 6 years and then expect it to run. Yes Dave it has been a while. I had a bit of a break to concentrate on my business and I finally may get some time for myself to do a bit of flying. I have gone to the dark side and am in the process of getting an electric contra model up and running. I simply want to get some flying under my belt to try and get my fingers working again - best way is to get my old IC model flying so I can enjoy my 12-15 minute flights before I have to settle into 8 minute flights. My havent things changed in 6 years - 2.4G radios, electric F3A planes OMG everyone speaks a completely new lingo at the flying field. Screw drivers and spanners have been replaced with multimeters and soldering irons. What will the next 10 years hold? Cheers, Peter

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
I have taken delivery of my Contra Drive and I must say the quality of workmanship and attention to detail is outstanding. Well done Brenner and team for making this product available to the comsumer market. I have a question in relation to the Hyde mount and Neu F3A motor setup when using the Contra Drive. The following photos show the complete assembly with the drive, motor and mount. I assume that the Hyde mount is installed as shown however the mount covers the cooling fan section of the motor. I cant rotate the mount 180 degrees because the hub of the contra drive is too wide for the mount. Am I using the correct Hyde mount? If I am have I assembled all the components correctly? If all the above are correct will cooling be and issue in this configuration or do I have to modify the mount? Thx Peter

RE: Da-Ja-Vu Build thread
The carbon wing tube in my CA DeJaVu model is quite loose especially in the wing sockets. Does anyone know if PBG have a drop in replacement which fits nice and snug (and possibly save some weight at the same time) Secondly, Is the single wing bolt adequate? I find when I tighten the front wing bolt the rear of the wing pulls away from the fuse slightly - I guessing this is due to the loose wing tube in socket. Thx

RE: NSRCA Candidate Rules Proposal Survey is available
I have not followed this thread closely however I could not help notice the amount of emotion which is being generated about this particular issue. Tha fact that this is an AMA matter then it really isnt any of my business to comment as I live in another country however I dont understand why the AMA simply cannot raise it's weight limits by say 5% which would probably allow most of the 2x2m meter models which are slightly over weight to compete. I would think more than 90% of overweight cases would fall within this bracket. As for the models which are heavier then I dont really think it will matter as most of those modellers may not be serious enough or interested enough to compete at the nats. I cannot see any case where raising this limit by 250grams will disadvantage the guy who wants to fly a model which weighs less than 5000 grams (glow, electric or gas). At least if a guy who currently flys F3A wants to compete at the nats with an overweight model he can at least fly in Masters class (assuming this is allowed) were the weight limits could be slightly higher. Given the current financial climate and the dwindling number of aerobatic flyers we need to do whatever we can to keep the ranks. Everyone benefits if more aeromodellers are involved in Aerobatics! Just seems like common sense to me - Peter Australia

RE: YS DZ 175 advice required
Hi Ed thanks for the Tech-Aero Ultra IBEC tip. I like it! I assume it gets it power directly from the RX connector bus. I realise EMF noise is no longer an issue due to the opto coupling. For this application is there any benefit having it connected directly to battery as my battery has 2 power leads. What is the fuel consumption comparison between (170-175 CDI) and DZ160. What I am trying to say is there any benefit swapping out my existing 20oz tank for something smaller? Thx Peter

RE: YS DZ 175 advice required
What are most people doing who still fly YS CDI in relation to powering the CDI unit. Are you using a seperate battery pack or do you share between CDI and flight control systems? I have seen a number of threads about this topic but they are all a little out of date. 6 years ago I was using a 2500maH Lithium Ion battery with a Jerrico regulator and futaba switch. I have just purchased a new Lithium Ion battery but would like suggestions about the rest of the power system should I decide to use a YS CDI equipped engine. Thx Peter

RE: YS DZ 175 advice required
Hi all, Thanks for all the replies. I wasnt expecting this thread to break out into a Electric Vs YS power debate however it makes for very interesting reading. My situation is that I currently have a very good F3A model which will get me back to a level of skill to compete in F3A however I need to put some time into flying which is the key for me at this stage. For the people that know me I have been a long time campaigner of YS 4 Strokes and I have had a very good run with them over thousands of flights for many years. My 160's are giving me some problems because I never stored them correctly prior to leaving the hobby 6 years ago and unfortunately I dont have the time or interest to get them sorted when parts are going to cost me as mush as 20% of the cost of a new engine. The electrics do appeal to me (especially the contra) however I dont want to make a choice at this stage as the flying is what really is important for me. My current model is setup for YS power and the conversion to electric will be difficult. Certainly this debate has got me thinking and asking myself if buying glow is the right thing to do. If I bought another YS I could be flying in 1-2 weeks however if I went electric it will be another 3-6 months by the time I get back into the air by the time I get a new airframe together and familiarise myself with electrics. Fuel costs are not a consideration as I have a large stock of fuel which is still good to use. Thx Peter

YS DZ 175 advice required
Hi all, It has been some time since flying pattern and therefore I need to get an existing model in the air to teach myself how to fly again. I have been looking at the electric options (which there are numerous) an I feel I am not ready to make a choice as to what to use at this stage. I have been trying to get a couple of old DZ160's sorted out to fly but I am not comfortable with the reliability and dont have the time to sort them out for the time being. I am thinking of purchasing a DZ 175 CDI (cheaper than what I paid for 160DZ's 8 years ago Hmm) however I need some advice 1)What props are people using on this engine 2)How much oil 3)How much nitro 4)Spark plug life? any additional information which will assist me to transition from a DZ160 setup. Thx Peter

YS 160DZ Help
I have been out of the game for almost 6 years and I am slowly trying to get my old gear working again before I take the electric route. I have 2 DZ 160 engines which were running perfectly before I stopped flying. I left them sitting around in the box without preparing them for extended storage (big mistake) and they have since locked up. I have managed to pull everything apart and clean carefully replaced all gaskets, o rings etc. I believe I now have a pump problem however I am not sure how to test correctly. The engine will pump fuel through when I turn it over with the starter but only when I pinch the line briefly between pump and carburator. This action cause the pump to start working. Once I get the pump to work it does not seem to have enough pressure to push fuel all the way into the injector. I have checked all the cavities in the carb and needle valve assembly and I am certain I dont have any blockages in this area. I have also checked the injector and check valve in the head and all appears to be working fine. I did a simply test by connecting the fuel line from pump directly into the head and the engine ran abeit very rich to confirm nothing else was wrong with the engine. My immediate observation is the pump is not producing enough pressure but I dont know how to test this easily or what part of the pump needs to be looked at more closely. Any suggestions would be much appreciated. Peter

I currently dont fly electric so I dont have anything to compare to but I am in the process of getting a model together and your product is being considered if I can get the model at the correct weight.
