RE: Bell X-1
I started with Cleveland plans since, of course , I live in Cleveland. Total mods were required becuse I am building something much larger. The prototype was only slightly larger than the world record model built by Mac Hodges' friend Stevens. My big X-1 required many more mods since it is bigger than almost all RC aircraft and many times the size of any model X-1. Obviously this grand attempt may prove to a step too far. Stay tuned.

RE: Rocket powered Bell X-1
Here's mine. The prototype and the full size Prototype ( less than 8 feet span) flys great, unless you go to full throtle (eg 220 mph) Then it disintegrates due to flutter Working to avoid this conclusion on the big one, which is designed to fly faster.

RE: ASM F-7F Tigercat
Hats Off! to pilots like Rocketman, Brad, Staggerflyer and Rick Avery. Most pilots can't land a twin with one out, even though they know the theory of opposite rudder and turning away from the dead engine. With electrics, its even harder since you can't hear and often don't know that one is out. Turbo Cat debuted at War Birds Over Delaware this week . Never would have thought we'd get a flightline position for our tent when so many were 6 to 10 tents back from the flightline at this enormous show. I've never in my life flown a model airplane with SIX others at once and wasn't about to start here. So it fell to my fearless 18 year old to do the honors.

RE: ASM F-7F Tigercat
Rocketman, I used the Robart since the ASM tank looked small and Robart was a known entity and fit nicely. I like touch and goes so use the tank a lot. Maybe the ASM one is adequate; don't know. I'm not sure about the magnitude of counterrotation benefit in an engine out situation, but think you are correct. It does not outweigh all the problems or assure safety. The benefit is only marginal, perhaps 20%, but thats enough to make me a big fan given the gravity of engine out situations. My only experience is with the takeoff runs and flight tracking straight, proving some effect of counter rotation. My understsanding is the engine out advantage is only partial and only if it is the left engine you lose. If you happen to lose the right engine the remaining (port) engine rotation direction creates a vortex automatically pushing the vert fin toward a left turn. This partially corrects and counteracts the powerful right turn tendancy of the single remaining engine. That is, it automatically, immediately and constantly fights against the normal death spiral even if the pilot's human reaction isn't so quick or correct. If you lose the left engine, however, you have none of the countervailing force, only the death spiral force from the remaining (star) engine, unless it counterrotates to give the correct pressure on the vert fin (correct torque, correct p factor ,etc.). One of the contributors to this thread who has great workmanship may also be expert in the dreaded engine out . On RCG he recently posted a video of his Tigercat crashing after engine out. His skill may explain the minimal damage for the most part. But it looks as if his right motor was the one lost, in which case the remainiing motor would have worked with him to a limited extent, in overcoming the greater force of the death spiral.

RE: ASM F-7F Tigercat
On mine, I always fill to 100 PSI, but I replaced the tank with a standard Robart. For props I use MAS 16 x 10, right out of the package with no trimming or balancing. Since mine is the earliest turbine version I may have more clearance. I could have fitted a larger DIA prop, but this was the largest I could get form MAS with counterrotation. Electric has many drawbacks but one of its advantages is the ease of achieving multiengine opposite rotation. In addition to eliminating Torque, P factor, etc to get straight runs and flight, it increases the odds of surviving the dreaded loss of one motor. That overrides everything for me since the biggest failure of my RC career was loss of my Yellow Aircraft electric P-38 on maiden due to motor out.

Bell X-1 Project
Seems as if almost no one has done an RC X-1, at least not a large one. When I wanted to try I found almost nothing on line . This post is for those interested in this hugely important, terribly famous yet nearly never modeled plane, so you will know you're not alone. My X-1 project increases wing area to enable ROG, while eliminating the humps on the top and bottom of the fuse to return to the "true scale" of the original bullet design before the Bell engineers were forced to compromise as the project progressed. My prototype is a few inches bigger than Mac Hodges (the largest example I could find). It takes off from grass and flies great with a foldable prop in the nose. The big one will be jet powered. The challenge is to do this without detracting from the pure, streamlined X-1 form. So it will have no prop, no jet intakes or other adulterations visible. Er, thats the plan anyway. Stay tuned to see if it works.

RE: ASM F-7F Tigercat
Such a shame to see that beautiful staggerwing damaged. If misery loves company, my Turbocat was significantly damaged when 1 wheel fell off on takeoff. You guys who say ASM is prone to excessive damage are right, but also those who appreciate the lightness and low cost. I see one guy criticized my Turbocat's "modification" to turbine (actually electric) power and streamlined nacelles. Anybody who builds a Tigercat with big, radial engine nacelles can be proud of accuracy to historic, production models. But there is nothing wrong with true scale to the original design inline or turbine engines. Imagine a P-51 with a radial engine. The history of aviation is all about modification. Otherwise we'd be stuck with biplanes, with wing warping instead of ailerons, with propellers instead of jets, etc. Now that the Turbocat is repaired and flying again, it still has a strange deficiency. Has anyone else notice twitchiness or Unstable sensitivity? Seems like I have to focus-fly this airplane every second or it goes toward earth. I am at a loss to explain this given its ample empennage and dihedral.

RE: YT (ESM) 50cc Spitfire
Wow this is great timing. I just did the maiden of this plane with an electric conversion last weekend and it was awesome! Im running a Rimfire 50cc motor with 10s series 45c Thunder Power 5000 mah packs. Weighs 24.5 pounds (batteries up front so no lead) . Gets 5500 watts. Thats about 225 watts/lb![:D] Maiden went great, and second flight was some of the most fun I've had with a plane. Everyone loves videos, and I'm afraid I don't have a full flight, but there's a short clip of flight 2 starting on 3:58 of this video: http://www.youtube.com/watch?v=2vqrTRPYnEM

RE: ASM F-7F Tigercat
Maidened mine today. This is the T model, but its no Model T. The Grumman Turbo Cat. Fantasy Scale. Its my concept of what the designers originally intended the T Cat to look like. They didn't design such a sleek, streamlined fuse only to stick 2 bloated radial engines on. With the turbine version's superior streamlining, I expected the top end and energy retention to shine. Its real fast and just keeps going. The surprise today was the glide. Despite the heavy wing loading, no problem shutting both motors off indefinitely. Even thermalled for almost 30 seconds. Yes, continued to gain altitude with both motors off for 30 seconds. What?

RE: ESM 89 in. Spitfire build!!
I just finished modifying the wings for the Sierra retracts. Getting them to fit was not that bad, the only thing that annoyed me was that the front piece of the base of the retract unit hit one of the spar supports. I ended up cutting about half an inch off the corner of the unit. This all was not too difficult, though; i got the second wing done in just over a half-hour. If anyone want's pictures, I could provide some. Ed

RE: BH Models Ryan STA 46-61 ARF
Mine came out at 8 pounds with a 60 sized electric motor. Overall, I would say it flies "scale" (which means it could use some more power.)

RE: BH Models Ryan STA 46-61 ARF
I built one back in june and have ben flying it regularly all season. It wasn't the easiest airplane to build, as there were a few poorly drilled holes (mine was from an early run, so this may have been corrected), and lots of plastic to cut out. I also did the electric conversion, which complicated things a little, but was not that hard. The landing gear on mine were pretty bad, as they were made out of a material that bends, so even on decent landings, they would be bent out of shape. Needless to say, the wheelpants did not last long... I replaced the stock gear with Robostruts, and that has taken care of the problem. It flies real nice, though, with no bad tendencies, the only tricky part is landing in a moderate to strong wind, as the wind will cause the plane to become unstable near the ground. Usually, this results in the Ryan picthing up and down, and makes it tough to grease the landing. Overall, it is not a beginers plane, but by no means is it hard to fly, as long as there is not a strong wind. It is also a beautiful airplane, and really stands out at the field.
