RE: Zenoah 26 upgrades
If the G-26 is anything like the G-62 adding a tuned pipe will provide a healthy increase in power. The other items may improve the general operation of the engine, but I doubt that they will add much to the power. As an example going from a canister, possibly on too long a header, to a KS 1060 tuned pipe, gave an increase of 700 rpm on an Engel Super Silence 24x12 2-blade. From 5.900 to 6.600 rpm. And that´s easily felt in the air. :-)

RE: Weatronic 2.4 RF diagnostic tool
As far as I know Wea will be launching a dedicated tray type TX later, since this design is very poorly suited for use in a tray, as a good portion of the switches will be located below the tray. Not a good idea. :-) Personally I´m not crazy about the look, but it´s starting to grow on me, and it is the software/funktionality that´s important anyway.

RE: Weatronic Transmitter
The only picture, as far as I know, of "The real deal"... http://www.rc-network.de/forum/showthread.php/349480-Der-neue-Weatronic-Sender Personally I find it extremely ugly, but as the functionality and reliablity is the importent thing - so who cares about the look. :-) But still, after looking at the pictures for a day or two, it looks better and better, and I´m looking forward to the tray type TX that should be out next. Could be my next TX... P.S. Added the latest "specs" as I read them on the above link. Hallsensors - In the gimbals I guess? WLAN UMTS - Some sort of phone network? 3G or similer? Bluetooth Color touchscreen by Samsung 22 "Functions" - As apparently the operating system does not use channels in the normal sense? Ready for 5,8GHz for FPV use. And there is a rumour that it will use dual batteries, which could boost duration, and also provide some redundancy in case a pack fails. Not that I have ever heard of any that did...:-)

Harry. I had seen the announcement a long time ago, but I was not able to find any info on the Fineworx company. Thanks for clarifying this. I have also heard that Wea plans on presenting their TX at this years Jet Power, but I´m not holding my breath. I have learned that the deadlines are never to be trusted...:-) But I have been very satisfied with my Wea gear, and everytime I have bought some products the response has been prompt, and in the few instances where I have had a question, the responce has been quick too. I know that others have had major difficulties in this regard, but for some reason I seem to have been lucky.

MVVS 152 and large propellers
Hello there. I have a King 140 twin destined for a 1:3 Wilga I´m working on, but for several reasons I´m considering installing an MVVS 152 instead. Can the MVVS be made to run reliably, and without overheating, at rpm´s around 4500 using twin KS-95 cans? Many King 140´s run SEP Wilgaprops, normally 32x10´s, at around 4-4500 rpm in order to provide a low noise, scale looking, setup, and I would also be using such a prop on the MVVS. SEP makes several other sizes, 32x12, 34x10 and 34x14, so one of them should load the MVVS about right, as long as it has the low end torque to run at such low rpm´s of course. The propeller in question can be seen here: http://www.sep-ls.de/. Click "Luftschrauben", and then "Wilga". In case the MVVS is not a good candidate, which other engine around 150-200 cc produces the low end torque to be able to run at such low rpm?

RE: Engine ID help
Mine did 8200rpm open exhaust, and 7900 with the DA 50 can on a 8,66in header, all on the APC 18x10. I don´t know the type of "muffler" that´s attached, but it does not look like it does much in the way of silencing the engine, so I would guess that you might as well run it without. It could be that this is holding the engine back.

RE: g-62 prop
[quote]ORIGINAL: pe reivers you must be talking of the 80cc boxer engine, not the 62cc single? [/quote] You mean me? Nope, a stock mag G-62. But it seems to me that the Fiala type propeller loads quite a bit less than the same size Menz for example. I used to fly with a Menz 26x8, and it would do around 5300 rpm. That was on a different silencer though (Toni Clark piper style). The bigger diameter propeller helps lower the idle, as I get a reliable idle of around 1000-1100rpm on the Tri-Pacer.

RE: g-62 prop
Precently I´m using a Fiala 26x8 on my G-62 equipped 1:3 scale Tri-Pacer. The tips have been rounded to make it look more scale, and the engine spins it at around 6300 (6100 before rounding the tips). Plenty of power for a 37lb big fat pig. :-) P.S. I´m using the stock twin outlet silencer, with a 2-into-1 collectorpipe. Very noisy unfortunately, but the fact that I hardly ever gets over 1/2 throttle helps a lot.

RE: MOKI RADIAL Care and Maintenence
Thanks for the clarification Mick. I thought that there must have been a good reason for not using both system at the same time, and an elevated fuel pressure, with both systems operational, would indeed leave you in the same mess if one of the systems failed. Too bad though. I have talked to two friends flying the Moki 250, both using the APS 380 fuel pump, and both agree that the engine runs more reliable, and with much crisper throttle response with the pump. So I will most likely follow suit and use both fuel pump and turbulator. One more thing. I know the websites of the companies selling both the engine and the fuel pump, but have been unable to find anyone selling the turbulator, other than Vogelsang in the US. But being located just north of Germany I would rather like to avoid having to order the part in the US, and having it shipped back to europe. My modest contribution in the fight against global warming...:-) Do any of you have a lead on where to buy it? If I buy the Moki it will be going into a 1:3 Scale PZL Wilga I have been working on for some time. It was originally destined to recieve a King 140 twin, but (luckely) it developed some problems, and I thought the best cure for the following depression, would be to buy a nice shiny new toy. :-)

RE: MOKI RADIAL Care and Maintenence
Hello. I posted a question regarding the Moki 250 in the gas engines forum, but got no replys. I´m not trying to spam the forum, but maybe those that may know the answer, have not seen it there, so I´m posting it again here. [i] I´m considering buying a Moki/RCS 250 radial, and I have worked myself through most of the huge thread concerning this engine in the "Warbirds" forum. One thing that many suggests is to use an electric fuel pump, like the APS 380, to stabilise the fuel supply, and avoid the possible problem of a clogged vacuum pulse tube, which could lead to a lean run, and possibly shut the engine down. When doing so, you are instructed to remove the tubing from the engine driven pump to the carburettor, and rely fully on the electric pump. In my view you then have exchanged one failure source with another possible source of failure. If the engine driven pump fails, the engine stops. If the electric fuel pump fails, the engine stops. Is it not possible, to use both at the same time, thereby providing true redundancy? Looking forward to your input. [/i]

RE: 100 OCTANE aviation fuel in gasser
Isn´t the AVGAS way too expensive to consider running in our gassers? Here in Denmark the price of AVGAS is at least 30-40% higher than that of regular MOGAS. MOGAS: about 9$ a gallon. AVGAS: about 12,50$ a gallon. The only thing more expensive than AVGAS is Aspen pre-mixed gas, at 20,50 to 23,50$ a gallon. :-) Thinking about these prices makes me glad I have a car with a tiny engine.....

Flying. Wendell Hostetler 1:3 scale Piper PA-22 Tri-Pacer. This weighs in at 37lb, and is powered by a G-62. Using the above mentioned formula this takeoff weight matches a full size Tri-Pacer with two persons onboard. :-) http://www.youtube.com/watch?v=YmxEUtObisk Under maintanence. Toni Clark 1:3 scale Pitts Special S1-S. This is a little lighter than predicted, weighing in at around 19lb. The formula predicts around 22lb. It´s also powered by a G-62, but I may install my GT-80 instead to be able to drive a little more prop. Building. Frisch Modellbau 1:3 PZL-104 Wilga. This is to be powered by a german King 140 twin, and I expect a takeoff weight around 52lb, which matches the formula quite well.

RE: 25% Cessna L-19/0-1 Bird Dog build
With regard to the scaled weight of our scale models, the "correct" way of calculating is like this. For a 1:3 scale model. Weight is divided by 3x3x3=27 Area is divided by: 3x3=9 For a 1:4 scale model Weight is divided by 4x4x4=64 Area is divided by: 4x4=16 Going with the example mentioned earlier we get 1:1 scale model Weight: 2400lb Wing area (according to Wiki): 174ft² Wing loading: 13,8lb/ft² 1:3 scale model: Weight: 88,88lb Wing area: 19,33ft² Wing loading: 4,59lb/ft² 1:4 scale model: Weight: 37,50lb Wing area: 10,87ft² Wing loading: 3,44lb/ft² What I have found is, that instead of using the cubed scale factor (scale^3), I use (scale^3,5), and get results a bit closer to the normal numbers for the 1:3 scale models I prefer. This gives the following numbers 1:3 scale Weight: 51,32lb Wing area: 19,33ft² Wing loading: 2,65lb/ft² 1:4 scale Weight: 18,75lb Wing area: 10,87ft² Wing loading: 1,72lb/ft² As can be seen from the above, the numbers "fits" the 1:3 scale model the best, while the smaller 1:4 models normally builds heavier than predicted by this.
