Designing your own C/L airplane
« on: July 17, 2011, 03:41:11 PM »
  I know that when we were kids most of us got the engines off those Cox plastic models and either got a Scientific kit or designed and built a tiny model that more or less flew. But that set up the glue of modeling that has lasted for the past 50 or 60 years now. I have been back into modeling since the spring of 1999. My first 12 or so planes did not make it much past a few flights. Usually the engine would flame out in the overheads, a wing was warped and showed up at a most inopportune time in flight, or my handle was out of adjustment and I did not compensate for that in a outside square manuever. Now I have around a dozen planes RTF and that many more wings and kits to build with engines for all. This past Christmas I was in Roy's Hobby Shop in Hurst, Texas and I laid eyes on the Brodak Legacy. Their price was about 15% less than I could order it from the manufacture. I laid out the plans and studied them closely. I had an extra S/Chipmunk foam wing panel that I had purchased from Model Wings of Marietta, Ga. some 10 years ago. It was about 11% shorter but the exact same airfoil as the plans showed. So I built a .40 size version of the Legacy. It flies wonderfully. I am looking forward to feeling better and building two full size versions of the kit. I have a NIB LA .46 and a NIB Avastar .46 to power each with. These planes will make a better presentation of the pattern than anything that I have ever flown. I have always wanted to design and build a CLPA model. And I have by using some tried and true numbers. But I simply cannot improve on the appearnace or performance of this design. Allen Brickhaus did a superb job on designing this model. When you have the best that you know of that pleases you then why build and fly anything else? Check them out......Jerry

you will struggle with a 46 in the legacy - unless you build it SUPER SUPER light....

You musta missed he's building 40 size Legacy"s

   So what do you think Allen; will a Avastar .46 power the Legacy kit? My M-O is to build and fly mostly .40 size planes. I do have a .25 FP on a Ring Master to use at the Ring Master Round Up. I also have a few new .35 FPs in the box. I doubt that I will ever build or fly anything any bigger than a .46 size plane. At this point I can shrink the wing and fuselage by 15% and still have a nice flying .40 size ship as I have already done that. Hump, I will take into consideration that the .46 may not be powerful enough for this plane. Bench running the Avastar it seems to run real strong. Light will be the key I suppose..........jerry

"looking forward to feeling better and building two full size versions of the kit."

Guess you missed this line in his post!

the 46 wil be slightly underpowered - not sure on the Aviastar - but I built one with an LA and it struggled - Super Tigre 51 sorted that out - and now I fly an electric one which has TONS of power.

 I definitely agree that a .46 isn't quite enough oomph. The Saito .56 with a 12-6 Rev Up prop is an ideal combination for the full size Legacy. y1
