The first flight was a bit rich but the performance was better than expected. Even though it flew with the outboard tip a bit low, the entire pattern was done on the first flight. Turns out the inboard wing was warped down a bit and straightening was simple.
Subsequent flights, including those by a local top-level expert, point to a real winner. The plane flew through the pattern with silky smoothness and I really cannot suggest any changes. Individual preferences may dictate minor changes but the basic platform is very sound and should be a perfect supplement to the growing line of ARF/ARC offerings.
For delivery and pricing info, contact Brodak Mfg for the latest figures. As before, I will bring the Smoothie to the field whenever I go. Anyone wishing a “test ride” is welcome.
As we build more time on the plane, I will add to the report but as it stands, I do not anticipate any changes. I have forwarded the information to the manufacturer so what you see and read about should be about what you can anticipate for production.
The Brodak .40 in the Smoothie is one of the original batch – I have no idea how many flights are on it but it’s been on at least four airplanes. It was on the Cardinal ARF when it was splattered and suffered no damage. I have NEVER had it apart.
I read on another thread that people are modifying them to improve performance. I believe it was Phil Cartier that asked what was being done to them. I would make the same query. I’ve heard many run and the best were completely stock. I paid particularly close attention while judging at King Orange and Brodak’s.
Actually, modifying the engine does accomplish one thing – it voids the warrantee. The .40 was tested and developed by Tom Hampshire, who is the most knowledgeable engine man I’ve ever met. I would imagine it to be a difficult task to improve on his work.
I welcome comments and suggestions.
