Right now it balances perfectly with the engine and without the tailfeathers or battery. With the tailfeathers and battery against the firewall, it's tail heavy - and I haven't even covered the fuse yet. Problem is I'm using a lighter engine (the Wasp) and a NiMH pack instead of NiCads.

A Q-TEE with no fuel tank behind the firewall should balance OK, but if you add 2 ozs of weight behind the firewall [fuel+tank], you will run into what DT is facing. His solution to the problem makes the most sense, plus it is good that he caught the problem at this stage VS later on. I eventually ran mine with a TD on the nose and a TD strapped to a power pod above the wing, and that model had the coolest sound to it, like a siren.

Won't the fuel tank add to the nose weight? If there are balance problems anyway, I have a PAW .09 with no plane to put it on right now. I think the Q-Tee could be nice with that engine up front.

It's been awhile since I looked at that Airtronics kit, you are probably right about the aux. fuel tank helping the CG issue instead of hurting. I mainly remember mine and a friends' QTEE coming out tail heavy. The most experienced builder of our local group built them in batches from balsa sticks and introduced me to RC combat with this plane way back when. His planes were so very light, he also introduced me to cellophane covering and pull / pull linkage with carpet thread.

Well, after a long delay (things to do, y'know) I've resumed work. I should have it finished fairly soon now. Here's the nose extension...that 2oz tank fits in there quite nicely.

Your little Q-TEE should have pretty long run times with that 2oz tank in there. I used to run a Tee Dee .051 in a falcon JR and it would run on 25% for what seemed like about 10 minutes or so with a 1 oz tank, atleast here you will have the option to come down before your tank is empty.

Handy that the Wasp has a throttle. The club here is putting down a cloth runway - might be able to ROG, maybe even do touch-and-goes!

I can't say I'm very happy with Oracover..I hope it lasts the season. Either way, this thing is going to be recovered with cloth (maybe Solartex) and painted with Nelson paint. I just hope to be able to NOT have to do it until winter...

Last roll of Oracover I bought didn't have that death grip stickyness you expect from an iron on. What is wrong with your roll?

Seems to stick 'OK' but it doesn't shrink well at all. Sits there and does nothing until I get it really hot, then it goes ballistic. I knew I should've gone with Monokote.

Well, if all goes well it'll be maidened tomorrow. Just gotta get the radio installed. As far as the weight, I don't know how accurate my scale is but it appears to be around 16oz with an empty tank. Should fly just fine at that weight.

Good luck on the maiden, I love when there's something new to test out.

Your rendition of the model lives up to it's name. Enjoy!

I'm glad it turned out as well as it did, considering it's been almost a decade. Hopefully these won't be the last known photos

Well, fly it does! It was almost as windy this morning as it was yesterday evening, but I called upon my manhood and gave it a go anyway. It rose right off the runway and flew pretty well. As windy and gusty as it was it got tossed around quite a bit, so I don't really know what it's going to need for trimming yet. I can say it obviously doesn't have any major problems. I flew it around in circles a few minutes, and even dared a loop. I cam back aiming for the pad runway, but as I got close the wind pushed it to the side onto the grass strip. It was coming in beautifully, but as soon as it touched down the grass brought it to a screeching halt. All in all, I pretty happy with everything considering that's the first flight I've done in about 10 years or thereabouts. Here's some pictures of the field and runway.

At least I don't have to make any repairs!

Well, flew the QT today in MUCH quieter weather. I need to do a little tweaking, but she's pretty nice. It was a hit with the other guys. One even commented on what a 'cutie' it was - should've seen the look on his face when I told him that was the actual name of it

One problem I'm running into is getting a reliable idle out of the Wasp. I had 3 dead stick landings because it just sorta petered out and died on approach....any ideas? Top end is plenty powerful. Running Sig 25% and an OS P8 turbo plug (cold) with a Graupner 6x3.

Congratulations, d_t. Sounds like a successful project. The idle is almost always the last thing to work itself out when breaking in an engine. The more you run it the better it should get. But, this is a simple carb without an airbleed, so it might always load up a bit at low idle. How is the tank situated in relation to the spraybar? Lowering the tank a little bit could help if the idle is too rich.

Sometimes it is because of lean and sometimes rich. I have a couple of thease wasps and they like different tank heights and are quite sensitive to the mixture. Play with the tank height. If you need to rubber band a tank on the side so you can move it around while trying to figure it out on the ground. Somtimes they won't draw fuel too well.

If it won't draw fuel well you can make it draw by puting a TINY notch in the bottom of the barrel with a Dremmel where it is closing at idle. Putting a notch in the top acts like an air bleed but also reduces fuel draw. Did I enfisize TINY well enough? If you mess up carb parts are pretty cheap. You can also notch the aluminum carb body which is easier than doing the hardend barrel

I'm getting near done with the plane I'm putting mine on so I will soon find out if I can keep mine running at idle.

What are you using for a glow plug clip? I just modified an old Cox clip but haven't tried it yet.... I need to go to Radio Shack and see if the have a single D cell holder.

Treven.

Nice going!
It isn't always the case, but if it is deadsticking towards the end of the tank, it is dieing lean. Fuel draw will peter out if the muffler pressure is random and the fuel level drops too far. High temp silicone might be the answer to a leaky muffler, and tie wire it to the case. The venturi size is a compromise between full power and fuel draw. If you let it idle for a minute, then pinch the fuel line momentarily, the engine should keep running. If it dies easily, it is too lean.....if it speeds up, then the opposite is true.

I'm using a regular DuBro clip - gotta chuck the hypercolor turbohead into my lathe and widen the hole around the flats, though - it doesn't fit on far enough.

Unfortunately, shifting the tank position is a no-go...not enough room. Hopefully it'll sort itself out after a while.
