[quote]ORIGINAL: Edwin Pete, I'm planning on using a 8oz tank. I usually set my timer for 10 minute flights with a little left over for reserve. Any idea how long 8oz will give me? Edwin [/quote] Estimate .5 oz per minute full throttle once broken in... So 15 minutes easy for general flying.

RE: OS FS26???
[quote]ORIGINAL: klord125 I would love to build a Tiger Moth or SE5A to put this in. I just scratched a 52"ws SE5A. It was an English plan and designed real beefy/heavy. I made alot of changes to lighten it up but not hurt the integrity. I'm not sure these set of plans would be the ones to shrink. What do you think of a Sopwith pup or Camel?? I have a set of plans for a Sopwith Pup I think 52-55"ws that I can shrink down. Its all built up but I could probably build it pretty light. Any suggestions? Thanks Ken [/quote] The late David Boddington designed a very nice pair of biplanes for the FS 26. a Tiger Moth and a Gypsy Moth. Both are simple buids for 3 channel, no need for ailerons on these old bipes, they look silly doing aileron rolls anyway, much better a barrelly rudder roll. I have digital version of the Gypsy Moth, pm me if you want a copy emailed.

RE: A pair of Burfords back to OZ
Venturi on bottom is the Elfin replica. It was fairly common in the early diesels, I think they were worried about flooding. Other examples from about the same time (1948-50) have the underslung venturie.g. K Kestrel, K Falcon, Elfin 2.49, Elifin 1.8, DC 350 and several others.

A pair of Burfords back to OZ
A lucky find on Ebay (and low buy it now prices!) These engines were misidentified as Dunham's, but easily recognised as Burfords now back home in OZ. They were both stuck but freed up fairly easily by taking off the head and backplate then using a rod in a drill press to push the contra and piston down to get them moving (avoids strain on the conrod). A little polishing to remove the head scratches and they look almost new. Both run well, one or two flick starters hot & cold. The Elfin 2.49 replica has a rectangular bolt spacing so does not quite fit the same mount as the original Elfin. The Elfin has a cracked prop driver so was tested with the GB's - another little job on the list. The GB 250 is a replica of Gordon's early Sabre 250, but is a kind of halfway house between the MkI and MkII versions.

RE: Club Mills!
If you have a look back on page 1 of this thread I posted a picture of my Mills, including Aurora 5cc RC and a 3.46 RC. I can confirm the 3.46 is a bored out verison of the 2.4. Mine ran quite well, and throttled well also, but the crank pin climbed out of the rear disc and seized the motor. A new disc should beeasy enough, it's on my list of jobs. The 5cc was in a Super Scorpion for several years. It's a heavy beast, but runs quite well on a 14x6 (about 6,200 rpm). The throttle is great brrrm, brrm.....(long pause) brrm like an old bus. It's being given a rest at the moment, replaced in the SS by a PAW 35 which does about 6,400 on the same 14x6, but with a much lower idle (less character but more fun for touch and goes). I've attached a photo of the Mills 5 cc in company with an ETA 5 and Wildcat 5.3.

RE: Club ED
A longer conrod reduces the side forces of the piston against the cylinder wall. I suspect they went for a shorter rod as they found that wear was nnot a problem and could geta more compact engine which was no doubt justa little cheaper to produce as well. The move to a plain head was probabaly to save cost also as they found the fins were not really necessary. Photo's finally loaded this time, see my earlier post.

RE: Club ED
As you can guess I quite like the odd ED. I have most of the common ones, but I'm still looking for a Cadet, Pep, Reed Valve Racer and of course dream of Miles. I've flown all the Hunters, also the Comp Specials (another ina plane up in the shed) and Penny Slot. Just building a slightly enlarged Malmstrom Mimi for a second Baby - it has very light RC on rudder-elevator so may be a little interesting! My plan is to fly them all eventually, but maybe that's a bit optomistic. In the meatime it's great fun to run them all from time to time (I have a VERY oily corner of the shed). Images won't upload , so maybe another day.

RE: Club ED
I have three Hunters, I'm pretty sure they are all the same bore and stroke, but the first model is taller due to a longer conrod and cylinder. Series I has a finned head and tall cam turned cylinder (has a bulged section for the transfer, long prop driver. Series II has a silid head, short cylindrical cylinder, long prop driver. Series III has a green solid head, short clinder and short green propdriver, green spinner (green parts were shared with teh Taplin Twin). All run really well, but I can't pick much performcne difference, certainly on the fairly large props I run. One has an ED throttle, I've found it works best on the greenhead which has the least sub-piston induction.

RE: General Das Ugly Stik General Discussion Thread
Hi Guys. I love the Stick info you have all posted. I'll add my bit here. In 1969 or 1970 ... not quite sure ... I built a Midwest Kit of the Little Stick. It was covered in blue Monokote with white wingtips and the tips of the stabs. Red pinstripes were used at the color transition lines. Surprisingly, it was relatively easy to see in a blue sky ... at least for my eyes at the time. The radio I used was a World Engines Blue Max single stick five channel system. The Rx and Servos were small for radios at the time. I don't know what the all up weight of the airplane was. I never weighed it, But it wasn't overly heavy. I powered it with a Super Tigre .23 schnuerle engine, which was one of the early schnuerle ported ones. Still, it provided enough power to pull the aircraft through the air rather well. Vertical wasn't what you would see today, but it was good enough to pull the plane through my favorite series of aerobatics, including a takeoff, vertical climb, stall turn, landing, takeoff in the other direction, vertical climb, another stall turn, landing ... repeat as long as you can stand it! At the time I was in the Air Force ... working as an AFCS or Automatic Flight Controls Systems Tech ... read that as an autopilot mechanic. I was based at Chanute AFB in Illinois and we enjoyed the luxury of flying at the base on one of the closed runways and we also had a series of grass runways to fly from. It was heaven ... We were about 1/2 mile from anything and it was FLAT as far as you could see. Talk about unobstructed approaches! We could also fly from the parking lot in front of the main hangars. This parking lot was HUGE and so were the hangars. One had a B-52 stuck into it up to the wing root, if that gives you any idea. I had been flying an Esquire, also kitted by Midwest ... a single channel rudder only high wing cabin model I had added elevator and throttle to ... about 52" span. Then I built the Little Stick as a replacement, and what a difference. It was my "High Performance" model until I got out of the service and returned to North Carolina in 1971. It finally met its end when I was practicing "formation" flyig with another club member. He was the lead and I began watching his airplane too closely. He tried a roll and I followed, but because I was watching the wrong airplane, I didn't give down elevator when inverted and the little blue stick took it's final dirt nap! Or grass nap since it crashed on the grass runway. Ah, well! Lots of good memories back then. Maybe it's time to clear off some space and build another one ... Maybe a twin FPV version?

RE: Schlosser 0.5 cc
I also have a Valentine 0.098. Whilst it is a very impressive piece of precision engineering, it really does not compare to a Schlosser. The Valentine is an interesting curiosity - amazing that it runs at all - but a Schlosser 0.25 is a fully practical and surprisingly powerful flying engine.

RE: PAW .35 TBR - new bearings and twin needle carb installation
Actually my 35 is running the old steel carb, not the Varijet. As long as the spraybar is correctly aligned I've had zero problems with this carb on the 35, a couple of 55's, an 06 and a 09TBR. However I agree they are ratrher crude carbs so it's not surprising that better/easier results can be had from more sophisticated carbs.

RE: PAW .35 TBR - new bearings and twin needle carb installation
I've been flying a plain bearing PAW 35 in my Super Scorpion for a couple of years - a great combination. I run a 14x6 wood (because I have a lot of them) and it turns this at 6,400 rpm. Idle is great, never bothered measuring it, but it's very slow -just the original PAW carb, no problems. Only issue is stopping the beasty. It keep running with the carb closed, just on teh air bleed - and it will do this much longer than my patience lasts. Standard method is remove the fuel feed - a good party trick as it idles on for anothetr 30 seconds with no connection. Not a lot of power - but got to love it anyway.

RE: Aquacraft Rio 51z
[quote]ORIGINAL: Planejaw Well, last night at the lake wasn't so bad. My son's flex-shaft held together, no problems there. Cranked up my ship, put her in the water and about 50' from shore, the engine quit...just as I was starting to get her going. Brought it back, adjusted the low-speed needle and the high-speed needle a little (maybe because I was using the new NGK plug?). Back in the water, she ran just fine. Good low and high speed running. No misses, no problems. Went back to 16:1 oil mix...just to be sure. We had three good runs of 8-10 minutes each, then a good cool-down in-between. We've designed a cooling system that uses a Sullivan Streamer 6-12 volt fuel pump, gallon of water (or just draw water out of the lake with a filter on the end of the tubing), then hook the other end up to the brass, water pick-up tube. With a ''T'' fitting, can cool our two boats down at one time. Run a 2-cell lipo and you get a nice cool-down following a run. We can meter down the volume of water being pumped with a small fuel-line clamp, so there should be no fear of shock-cooling the cylinder down. I'll get some pictures this weekend. You can really tell the difference between the two and three blade props. Just by estimate, the three blade takes a little longer to get up to speed, but it's at least 25% faster on the the water. Of course, we're not running ours full out, nor are the engines leaned for max performance. Still a lot of break-in to go and we're not going to do any serious racing. Running ''formation'' with boats is about as tough as flying formation with RC airplanes. We were able to get three, 8-10 minute runs on one tank of fuel. When we were done, there was about 1/4 tank left in each boat, so we could have probably run the boats for one more 8-10 minute run, but with little reserve. All in all, a fairly successful evening.

RE: Aquacraft Rio 51z
[quote]ORIGINAL: Planejaw The plug looked good when I pulled it. Not fouled and gap just under 0.027 in. Light brass brushin cleaned it up, no carbon to scrape off. Put on a new NGK, just to be sure, gapped around 0.025 in. Too may storms around southwest Michigan last night to get out to the lake. Maybe tonight. Re-silver soldered my son's flex shaft last night. Got it good and hot. Used some new rosin core silver solder, plenty of flux, then some silver-solder paste (which contains silver solder) also inside the steel tube. We'll see how well that combination holds up. Wish I had welding equipment. I'd weld the flex-cable at the top of the steel tube, then never have another problem with it. [/quote] Funny - Last night I couldn't get my weedeater to run past mid-range - Same gas/oil and everything... Googled it and read a few responses about the exhaust getting clogged - That was it. Amazing what a small passage there is for the exhaust to keep things quiet - Cleaned out the carbon deposits and now she runs like a champ. Not sure what muffler is on the Rio but can't hurt to check that as well?
