Justin,

I now have 177 flights logged on my Sundowner powered with a BME 50. The airframe is holding up OK.

Could someone provide me the width dimensions of the Sundowner fuse at the pilot seating area?
Sure would appreciate the info!
Thanks

Mine is at my Dad's house so I can't give exact but if I recall it's about 7" on the outside. Here are a few closeups.

It looks like 6.5 inches on mine. What do you have in mind? I have to agreee the plane is a lot tougher then I thought initially. A Moki 2.1 runs in the 120's on the race course and stands the turns just fine that doesn't men it will withstand full throtle blenders but it is a legitiamate fun to fly pylon racers. For the record I have doen a dozen rolls and a few loops with mine in 50 plus flights. My Sundowner has been sold to a team mate who flew it to first place in the gold last year at Parker AZ so I am installing his Moki in it for our race in Ashtabula Ohio in two weeks,

I was wondering if the RARC 33% helmet or full face pilot would fit in this tight cockpit. The helmet head that is included in the box really is one of the better looking ones IMO - but some folks always will want different.
I see now from closer inspection the turtledeck forms well forward of the seat back. It does appear as if only a head (and no torso) would ever work. So the full fuse width really was the wrong dimension to request.
Our helmet; head only- is 3" wide and 4" high. (Full face is 4 3/8" high with visor and nut) This 33% may prove be way too large all the same for ths 25%er, tho most planes look better with a larger pilot -inspite of the actual scale relationship.

[Sparky69]

The head provided wiggles enough with the Moki in the plane to touch both sides of the canopy.
You can see the rub marks were it touches. Bigger will not fit. I bet I saved you at least $50 on that.
Good luck and get out and fly.

Hi Everyone,

I’m assembling my Sundowner at the the mo and reading through looks like my trusty Moki 210, Perry blue pump and using a 17 x 12 APC will be a good start.

I’ll flying for fun; no competitions over here and wanted to ask …the control surfaces are a little smaller than what am used to though guess they will have good effect at speed, are the manufactures recommended throws good, the lighter hollow tail tubes plenty strong enough, and servo’s any one recommend the oz/kg required using a regulated lipo at 5.1v?

The hollow tail-tubes are strong enough, but you may need the solid steel ones for balancing the Moki. Only you can determine that. Most any high-quality "normal" sized servos that have 70 oz. in. or better will work fine. I used Hitec HS625MG servos...

[Sparky69]

Mine was set up for racing and on mine I used the hollow tubes and put the battery in the back on the rear hatch. No pump, muffler pressure only from a Brisson muffler. Start rich and watch it come up to speed as it leans out. Any of the std size digital JR servos should work. The CG should be a little fwd of the book value at the beginning and use a broken in engine, dead sticks can be difficult it must glide fast. An additional cooling hole will most likely be needed on the bottom of the cowl, behind the cly. Leseirf might be able to post a picture of his for you.
Good luck!

I was at the URSA Pylon race yesterday, near Astibula Ohio. This was the first time to a race like this. I been wanting to go for several years. Now I know what I was missing. The Sundowner race plane looks like a lot of fun. If I was not 65 years young....I would try it for sure. If you like speed and can fly smooth...this is what you want to try at least try once.
