Tempest

To: SHHOLT--Thanks for the nice comment on my late Tempest. Goes to show you that 90 degrees or so for several days in March will pickle a Minnesotan's brain. We are only "summerized" for 50 above zero in march according to the official minnesota rulebook. (note: from September to may, all temps are either above or below zero in Minnesotan.).

Seriously, the plane was capable of surviving but I just blew it.

My wife says we can't go next year unless I get another one built, so I ordered another kit from Eric while driving back to Minneapolis. It will have roughly the same color scheme and cockpit set up ( although the pilot from the cockpit of the wreck says he want's an airbag in the next one!!!!!)......

The one you saw had a K&B 40 (model 4011) which ran fine but weighed almost 15 oz with muffler. The model was built to accomodate that heavy engine with heavier tail feathers etc, and weighed 53 oz, balancing on the money. Since that was my first stunter in 28 years that was good enough, but the next one needs to be better.

OK folks, what do you all think for power? Tempest has 610 squares. All other things equal, a Brodak .40 and lighter tail feathers would build out at 46-47oz.

Thanks, Jeff.

Jeff,
It was a beautiful bird. Sorry to see it gone. You guys are way above my level on flying, but if you are looking at engines, the Magnum 36 XL makes great power, is easy to run stock, is fairly light, and above all is cheap. Another great choice would be a Byron Barker reworked Thunder Tiger 36. Just so you stay confused, if you can get ground clearance for a 12" prop, Leonards rework of the OS Max 35 FP should work. The OS 46 LA probably also fits this size airplane very well. Lots of good choices at this size.

The older I get, the better I used to fly!

LA 46.. Plug and Play

Jeff,
I was sorry to hear what happened at VSC. Gotta go with the OS 46 LA. I had one in my plane last year and it ran great. Lots of power and a good weight too. Lots of info on the set up too. Do a search on this forum on OS 46 LA setups and you'll see my set up in detail along with others. See you at Polk City?

I think you should use the Brodak 40. It has lots of power and will fly the tempest great.Plus you won`t have to put tail weight in it for the heavier engines. I have a Brodak in my Heinz-57 and put a smaller venturi and dropped to 5% nitro. Still had plenty of power. It will also save two ounces total off the plane. Should be able to build it at 42.

Just my opinion though

Jeff, so sorry about the Tempest. Watched this one grow through the construction and testing phases. A little like losing an old buddy.

Three days at 90 degrees is only about long enough this transplanted Texan to stop shivering. Saw my first Minnesotans of the year in shorts this week.

Gordon:

I'm leaning in that direction. The light weight of the Brodak and what I've seen of them makes sense. I like the LA but it's heavier.Going to a .46 would force me to use .018's, which seems self defeating, and an LA .40 seem's heavy, at least in a classic where you cant tweak the lengths.

Thanks for the thoughts and assists at VSC.
