Re: Need Your opinion on what plane to design
John, I'd vote in favour of the Clunk (CF-100) or the Jetliner.
Also, I'd like to suggest the SAAB J21R, which was the first and only prop plane converted to jet power. http://en.wikipedia.org/wiki/Saab_21R Scale plane and one to satisfy the Boomerang AND PushyCat crowds. |

Re: Need Your opinion on what plane to design
BTW, the widowmaker ws the term used for the F-104 variants that were used for low-level operatiuons rather than the intended high-altitude,high-speed interception.
The CF-100 was called the Canuck (official) or Clunk (unofficial and favourite name) or "Lead Sled" (on those days when nothing seemed to work right.) Speaking of your Mk4 variant. There won't be much re-engineering needed to convert it to the Mk1 (my personal favourite), 2 or 5. Idea for a extra kit parts. Also, any chance of making the Clunk as a twin-engine rather than a single with bifurcation (splitter)? |

Re: Need Your opinion on what plane to design
Ok, well, seems like the older plane will get the nod then. I forgot about the Vampire, as for up scaling the CF-100, even though I have a great model to take the measurements from, it's a whole lot of work. I think there are about 34 individual mould sections to make the one I have now. Dping this would mean making over a dozen plugs and I don't have the time to do that in one winter. Also, I would need turbines that are less than 90 mm diameter but still be able to generate about 12 lbs each, and be very fuel effiecent. Gary had tried it with twin Ram 500's and with the combined weight of the fuel, and the amount of equipment, it was just not possible as the wing loading was very high. It would have been a lead sled. Also, if you had a flame out in one engine, well, it would have been a bad day at the office. I checked out the JetJoe website and their smallest engine is only 55 mm dia but full thrust is 4lbs, their 12 lb thrust engine is 90 mm but I think this airframe is more suited for EDF, for reliablity and weight resaons.
As for the Demon, a possibility for sure, that big wing is very attractive. The only down side is the tail section hanging over the jet wash. I have a JetMach and have done repairs twice because of this feature ( balsa and fire don't mix.... ). I gotta get going now, will carry on when we get back from our tours. |

Re: Need Your opinion on what plane to design
Hey John
How about a 130 inch F15 ( hint, hint )Hope all is well I will order that canopy for you ,say hi to Dorothy for me PS hey how about we finish that 80 lb "conoe" in the garage ( Arrow ) Talk to you soon Ted |

Re: Need Your opinion on what plane to design
How about an F-5A then. There are F-5E's our there, Feibao I think, but not an F-5A. They've made it in both 1/7th which could be edf or turbine and 1/5th for the fellas who like em bigger. I've always wanted an F-5 but you can't find an A version and Canada didn't fly the E version. Its a proven model and we know a turbine will fit in it. Single only but thats cool.

Re: Need Your opinion on what plane to design
Hey guys, just got back to the apartment, just to let ya know, don't order a hotdog in Spain, not the same as home.
Yes, I would certainly like to do a Canadian plane but the choices are limited. Ok Ted, since you mentioned the 10 foot canoe in the garage, I guess perhaps "weeeee" should get it done and noooooooo, I don't want to do a big F-15, seen one, seen them all ( we'll discuss it when I get home ) Marty, that Mig, I really wanted to do one as EDF for the 120 mm which would be in the 1/7 -- 1/6 scale range, all depends on the size of the intake as I would like a 100% FSA with a close to scale internal ducting. Probably a little bigger than the Golden West Mig-17. Saying that, making it to suite both power systems is not difficult, actually, it's quite easy. But as you suggested, Ted wanted to do a biggie, hence the quater scale, I also had the drawings done at 1/5th at the same time and we both agreed that it would be a more manageable size plane, but still huge. Oh, one other thing Marty, Tad finally sent me the cannon fairings for that Mig-17 of his that you and I have. Would you like me to send you a set after I re-do them because, well, they're really "rough", basically unuseable. If so, send me your address via a PM. Byrocat, I looked at the drawings for that Saab, well, it's certainly not all that attractive a plane, is it. I do however, like the way the main landing gear retracts into the booms, gives me something to consider if I go ahead and do a sport model. I think I will stay with the CF-100 that I already have as my primary products will be EDF's. However, if you wanted to try one and get the twin small turbines to fit, well, I can pull a prototype fuse out of the moulds for you to use. If you can get the wing loading to a reasonable level it just might work and I won't charge you a penny for the fuse section that you will need, the rest of the plane, thousands...........or maybe a little less.....just kidding. I could pull you the main section of the fuse which is the front and the engine nacelles. The back section fits just behind the nacelles. If you can get everything in it without melting the tail section of the nacelle, then I will mould up the rest of the plane for you and we can come to an arrangement of some sort. Dale, the F-5 is a great suggestion, I always like that plane and when I was in the forces, had spoken to some pilots who referred to it as the sports car of the fighters. And since Canadair did assemble/make them for Canada, I guess you could say they were Canadian. The simplicity of the airframe is quite nice and has good lines. Would you have a source to obtain some scale drawings, most that I have found are three views without cross sections. Well guys, thanks for all the suggestions, hopefully some more chaps will offer suggestions, I'll check in every day or so and I will reply to everyone. |

Re: Need Your opinion on what plane to design
Just my two cents, but I dont think to many people want the fuss contributed to a TWIN turbine. Extra $ and Extra problems. Dont forget about the local(canadian) costomers that dont have a large budget. A twin turbine would start at $5000+ for the engines and electronics alone. I was under the impression that you wanted to build somthing popular that you could sell alot of. As soon as you mention Twin, You limit yourself to about 5% of the entire jet community. How often do you see Twins at the feild?
just my oppinion Trev |
