42% Dalton 300 or 35% Dalton 260?

So here's another question for you guys and this isn't something that's going to make or break getting a 40% plane. I'm currently using a Jersey Modeler 2.5 gal fuel can with the manual pump. Because I'd have to be filling up a 50 oz. tank, I'm going to get a Jersey Modeler gas can with an electric pump. Should I still with the 2.5 gallon and buy a 5 gallon to mix up big batches of gas or just go for the 5 gallon can?

2 1/2 or 5 will be fine all depending on how much you fly. Why don't you try one of these cans. I personally know the owner and if there good enough for QQ than there good enough for me. Rob

I'll look into them!

Ben, i already had a 2.5 gal manual setup from Jersey Modeler that i converted to electric using Dean Nistetter's (Magnolia, TX) setup. I had already bought a 2.5 gal full electric setup from Abell RC before I saw Deans' rig when I went to a 42%'er - 50 oz is a lot of handle turning!!. This gives me 5 gals if I need them. It is easier to lift a 2.5 gal can that a 5 gal one which is why I did it that way but you young guys don't have any problem lifting the 5 gal can - so go for it!

Ben, I would build the 42% and go with Da-170. Am hoping to take my dalton you sold me to the Dallas 3D fly-in. I have the 42% 300 and I can't wait to finish too, but am going to finish my 35% first. I have flown a 40% and OMG they fly nice. Just get the 42% dalton 300

From personal Experience, I Have flown both, and if you build it light, you can do the 40% on a DA-150 on stock Mufflers, with power to spare. The Extra 300 40% flies way much better, than de 35% Extra 260. More precise in overall. I'll say go with the 40% forget about triming the Wingtips, and make sure you build it light.

I agree.

Cool! I appreciate the info.

I'm pretty sure I'm going to stick with the DA 170 on cans as that's just my personal preference. I also plan on honeycombing the wings. I'd also like to just do 2 servos/wing and that's one of the reasons for trimming the wing tips. Jonas Pharr also did this to his Dalton 300. If I didn't trim the wing tips, could I still do 2 servos/wing or would I need 3?

The cost isn't a factor in this, I'm trying to keep things simple and I thought the airplane might snap better by trimming off some of the wing tip. Just a thought.

[Hector]

Trust me, the airplane is a great "Snaper", although my friend have 3 Servos on each wing. And in my humble opinion, you don't need to spend extra time in honeyconbing the wings. The airplane is a great airplane the way it is.

But if you enjoy these kind of projects, go a head with it and have fun with it. But in my opinion, other than making the airplane lighter, you have no need to change the desing of the airframe nor it's construction.

Regards,

Hector.

Anyone else have any thoughts about trimming the wing tips?

It's not that I'm doubting or not listening to Hector, I just want to hear what everyone thinks.

[smokin]

my thoughts on trimming the wing tips are simple.... tony designed a top of the line PRO airplane... if the tips should have been trimmed i bet he would have designed them that way. now, i'm not saying that it wouldn't be okay to do so, i just think that you are reinventing the wheel a little bit and it isn't necessary.

i have a 2 servo per wing setup on my mel... now, i have yet to maiden her but i am not worried about this at all. the third (middle) bay is still there so i'll use it if i find it to be necessary.

get the biggun' and LOVE IT!

[ben_beyer]

Yeah, I think I may just leave the wing tips alone and do 3 servos.

[BOSSIER_ROB]

You can leave the tips alone and still go with two servos. Just stiffen the aileron with some carbon strips. After Jer....uh , hum hum, somebody, flew Jonas's through the trees, we still couldn't break the remainder of the wings/ailerons, short of sticking them between two saw horses and jumping up and down on them. Those few thin carbon strips do the trick! There was zero flex in those ailerons. Two servos (inboard and middle) are fine as long as the ailerons are good and stiff. As far as the gas can goes, I prefer to use a 5 gallon can simply because one bottle of Bel Ray mixes with 5 gallons and I'm too lazy to fill a gas can any more than I have to. I just stuck a Greylor pump on the side of my gas can and use an extra 11.1v li-po for power. One last thing. If you're going to slap a 170 on that thing, there's really no need to honeycomb the wings, unless you plan to shave weight all around to shoot for a final weight under 36 lbs. It will still be a rocket, stock, with a 170.
