Status: offline 		ok, back on the bench tonight. i split my after work time between a little building and post sandy repairs to the house.getting back to the front bottom issue. the inside width of the fuse is 10 " that is set by the cutouts in f1. the plans show that front lower former as only 8 3/4 wide, and that was what the kit cutter supplied.of the 3 lower front formers only the one on the gear plate is correct. i ended up making 2 formers to fit the fuse. all the stringers are now in and awaiting sheeting. and again, all the top front formers are correct and fit just fine.

Status: offline 		HI Bob2t, Just want to make sure we're talking the same plane. after seeing your last post I went to the shop and got my plans out and did some quickk measuring. The bottom formers measure approx 11"right off the plans, could find none that measure 8.750.
Not trying to cause trouble just trying to help out. Are you sure your plans are for the 33%? Something doesn't add-up. When you have a chance check it out. My curiosity is getting the best of me. Joe

Status: offline 		 Hi John,

thanks for your response lot of helpfull information. Is it just a standard 32oz dubro tank?
also what size of spinner you guys use? I'm going to a big rc store in Orlando tomorrow so I like to pick up a few things.

also got a hold of a new dle-111, so probably buy a 28x10 prop at the store.

Status: offline 		Hi Martin; The Tank I used was an old Graupner tank I had for years but any tank that fits should work just measure space you have and use what fits well-The 2 blade prop will give very little ground clearance, I made the first few flights with a 27x10 but the blades would touch the ground at anything but level position as you can see even the 3 blade prop doesn't give a whole lot of ground clearance. the spinner is parabolic I got from Dave Brown at 4" dia which is scale as the Decathlons use 12 did but look at my nose and see that 3 3/4 might look better ?
cheers John

Status: offline 		John and Martin, I must correct one information here: the spinner of the FullSize Decathlon has varied over the years. The older models (pre-2004) had a larger bullet shaped spinner, and only the newer models (post 2004) have a smaller, parabolic (model-like) spinner. Citabrias always had a smaller Spinner than Decathlons. That used to be one hint to tell them apart at the first glance, besides the wingtips and profile, not to mention the painting scheme.
I used a 4 1/2 spinner as a rule of thumb for the 30%, and a 5 1/4 for the 35%, a 5 inch would be OK for any 33% to look right. Model Decathlons will always look odd if they have a spinner too small in diameter.

Have a good day
Marcus

Status: offline 		Hi Guys; The only reason I used the 4" parabolic is the my son owns a 2008 ( I think) Decathlon and it has a 12" parabolic style spinner I have no reason to believe it is not a stock factory spinner but may have been changed I will check with him when he gets back from his trip. But I think the 4" spinner I used looks too large on my plane at 33%. Oh well its not a true scale plane just something I thru together for a change from my large heave scale models cheers John

Status: offline 		if i may add my 2 cents to the tank questions. i have been flying large gas burners in imac for years. if theres 1 thing i learned, the rubber stopper in the tanks will fail/disinigrate/ melt with some of the gas additives in the fuel. the only safe tanks are the cap type as marketed by b&b [if there back] or aircraft international. i will never put a stopper tank in a gas burner again.

Status: offline 		First, I must thank Marcus for the good info as usual, I've built large scale planes with gas engines for yrs. myself and have always used the dubro tanks with the red stopper, you have to replace the black one with the red one, no problem. I just went to the BB web site and their tank looks pretty good, however never used one. About three times more than Dubro, I guess whatever floats your boat. Hey guys keep the posts coming. Joe

John you did a great Job on your Decathlon. I must however assure your spinner is not too large, actually it looks a little undersized, probably due to the "oversized (scalewise)" prop blades, if you take your son´s Deke´s spinner spec at 12" a third scale would actually be 4" which is correct. Then again I must alert ot the fact that the WH SD is not exact scale and the looks may fool one around.
Your full scale OK-DEC is a 2008 ACA Super Decathlon (cn 1081) delivered to the Czech Rep. AeroClub. It has the same 12 inch parabolic spinner that is currently standard at ACA, and which is actually much more modeler-friendly than the earlier model Decathlon Spinners, which I assume to be 15" therefore my previous information on the 30% scale at 4,5 inches would be correct.
If my information is inaccurate, and the older style spinner was only 14 inch dia. then 30% would be 4 1/4 inches, still using a 4 1/2 would be ok because the difference would be mere 1/8 inch ea. side, barely noticeably. But somewhere in the back of my mind it tells me 15 inch.

Have a nice Christmas ya all...and keep up those good jobs.
Marcus

Joe, to be honest I eyeballed the size of the antenna.
I am enclosing the side view of the SD so you can take your measurements and compare.
I don´t have the exact measurement, I have a mold I made - the base is resin cast and I drill a 3/16 hole on top to insert a 3/16 round dowel. The length will vary from model to model. Check the drawing...

Cheers and merry Xmas
Marcus
P.S. if you wish I can send you one, you can dremel it down to the needed size.

Bobt2 you have the option of doing it Oratex, all out in the colors you want, the only "paint" will be the FG parts (anyway) and one clear cote to seal the fabric, you can bring the plane over to a card bodypainter.
Less fuss with excellent results. Look at my page, the first 17 models were done that way. I then switched to Oracover, IMO far better than Monokote.

Cheers
Marcus

Bobt2 Ulracote is not the same thing as Oracover. Oracover has the same name worldwide. I am sure it must be available in good hobby stores or mail order services. Same for Oratex.
And Oracover is sure stronger, more opaque and more stretchable than monokote. I use no other product on my planes.
Of course, to go scale all out I have to use white or natural ´tex and paint and clearcote. Except for the pinstripes, which are tapes on the fullsize, you can use tape on the model too without spoiling the scale effect, it´s actually the opposite, you enhance the scale effect using tape.

How´s your build coming along? post some pictures, after all, it´s a WH building thread...

Cheers
Marcus
