Great Planes NEW 38% Extra

[Hinckley Bill]

Mark,

Understand about the weight concerns and appreciate any and all advice on keeping it down. I just don't care for DuBro, or Sullivan tanks and the "brass tube" setups required, that's why I like the B&B style of tank. What's the smallest tank size one should think about using with a DA150?

I have an 40 oz tank feeding a 3W150, timer set at 17 min and land with 15oz fuel in the tank, at 12 min I was landing with a half tank, going to reset the timer for 20 min and leave it there, thats a long time to be up and most of the time I land before the timer

I would think an 30 oz tank would be just the ticket, just do your own testing with flight times say 10 min to start and see what you end up with.

Mark is dead on, that seiko is old school and heavy, the 8711 combo with SWB has all the grunt anyone needs.

If you like, come out and fly the Cap, 37 lbs and change and then tell me why you think you need that Seiko, the extra battey and switch ( NOT )

You can use other options for tanks and set up the stopper any way you want, but I agree, the B&B tanks are TANKS!!! Various water/soda/juice bottles can also be used - it's a very popular practice in Europe and other eastern countries. They also tend to be lighter than even Dubro tanks.
As for the capacity, I guess it depends on how long you intend to fly and what types of flying you intend to do. If you're going to be doing mostly low, easy 3D and some hovering for about 10 minutes, then a 40 ounce tank will work. If you intend to fly IMAC, and compete, you need enough fuel to get through two sequences, and that usually requires at least a 50 ounce tank.
You have t think of this more like a 100cc plane, but with a 150 engine, and equip it accordingly. I know that Mith and Mark are enjoying theirs at their weight, but I'd be willing to bet that they wouldn't want the plane to be much heavier...
Save that Seiko for a bigger, heavier plane.

I wouldn't run smaller than 50 oz but that's me. I hate running out of fuel at the worst time possible. Those are some very impressive numbers Dave, but I'm lucky to have 8oz left after 12 minutes.

Copy that, haven't ran one dry yet, but I have seen it and it's never at a good time.

My 3W 75 is the same way, sips the fuel. I have a 40oz thank for it, timer at 17min and land with just about 1/2 tank.

Getting very close to a maiden on the Extra, kinda put it aside for the MM26/DA85.
They came 4 days apart, took the MM26 over to Al Smith's hanger and four of us pulled a gangbang on it, knocked it out quick.
will try and talk Al into another gangbang on the Extra and get it going, I have a 3W 150 on it, if she is a sipper to I will go with a smaller tank and save the wgt.
I have the CF wing tube, changed the wheels, machined the back plate on the spinner, dumped all the servo arms and links for titanium, two 8711 on rudder instead of three, no match box or power box, plastic hatch screws top and bottom,no choke servo.

More excited about how light I can get her than the maiden (lol)
Can't remember if Al said you are coming up in Aug, If you are I would gladly turn her over to you for a thrashing and opinion

Take care

I don't think canisters will work... just no space for it.
