At this point I have already glued the stock cheek cowls in place, so I am beyond the point of no return. Of course I have The Real Thing kit I plan to build in future, so it holds definite possibilities.

The horsepower and RPM figures between the TT TP-07 and Cox .074 Queen Bee were similar. I suppose this was to be expected as both are sport engines rather than high performance engines.

Looks like you're starting to really breath some new life into the old gal - that wing looks slick as a whistle.

I think you'll find the GP-07 performs head and shoulders above the QB, not so much in power, but in reliability, throttling and overall good behavior.

Hey guys finally got some more progress done on the scratch build. Time to cover! Looking to cover with monokote natural color / khaki or similar to give it a vintage look. Probably add lightweight wing struts too mainly for looks.

Looks Good Steve. I like the antique colors on mine, they just have a nice airframe for it

I'm with you MrGoodwreck and in a similar bout. Other priorities have delayed me, but my repairs are near finished, just need to complete them, break in the TT GP-07. Meanwhile, I've been flying my Sureflite 40" (1,016mm) wingspan foam Cessna 180 with Norvel .061 Big Mig CL. (Photos courtesy of Gary Jones, MADS RC Club.)

My very first R/C plane was a Q-Tee. I had a Black Widow in it and it flew very well. I had to shoe horn standard size servo's in it as I was a kid with a limited budget ( small servo's were expensive back then). I wore out about 3 of them. Lots of great memories.

Yup, you can build a lot for $61 in balsa (going cost as of now). In fact, one could cut parts for several and have extras, too.

If I only had a dollar for the ones that were "Here today, gone today".......... I am getting better about that though.

Yup, doesn't happen as often now, but when I was younger and less experienced, I Figure-9'd a 1/2-A pylon job on first flight. Crash was thorough enough that it wasn't worth rebuilding. (Had a light fuselage and foam wings.) It's not the only Figure-9.

I saw a club member lose control of a really nice large (1/5th scale?) ARF bipe gasser several weeks ago, about 150 yards out and straight in from 100 feet. It rekitted itself to kindling. Planes are a temporal part of this hobby.

Sometimes, the simplest solutions are the best for an old repaired airplane. Installing the TT GP-07 will require a new throttle servo, extending the needle valve and I don't have the proper threaded lock pin. A screw will work but will require trimming away a significant portion of the left cowl cheek, plus installing a fuel tank.

Due to close fit and servos are already placed, I finally decided to complete this plane by installing a Norvel .061 Big Mig CL engine with the 1/2 oz (15 cc) CL tank, with pick-up tube relocated to the bottom for more complete fuel tank emptying. Previously I used this engine on a venerable Sure Flite 40" span foam Cessna 180 of the 1980s. Even with the Mecoa standard long glow plug head with additional cooling fins (Texaco?), it pulled that plane briskly along even in windy days. This Q-Tee is considerably lighter, and as a two channel it will really move along, with generous tail control area, should be a decent stunt plane.

For me, it is evil but Happy Halloween. My Q-Tee should be ready for flight in the next few days.

You're going to love that motor on it! Mine's powered by the same setup turning an APC 5X2 when I want to putt, and a 5X4 when I want to zoom! I moved my firewall back about 3/4" when I built the kit and it fits perfect!

Certainly got to agree with you there, catracer. In this case I am using a 6x4 Masters prop, with the slightly lower compression it should pull this thing along with even more authority than with the heavy foam plane. I'm thinking I should be able to do a loop from level flight. When powered by a Cox .049 Black Widow, I had to build up speed from a dive to get it to that.

Q-Tee substantially completed, ready for receiver and battery installation, and flight testing.

Test flew the Q-Tee yesterday, getting in 2 flights with less than 5 mph breeze, sometimes gusts to 8 or 10 mph. The Norvel .061 CL/FF Big Mig is a really sweet engine, really hauls this 17.4 oz plane with authority. (Cox .049 Black Widow kind of poked along. ) Slightly tail heavy, so was somewhat touchy on the elevator, but still manageable. Had a helmet cam (Vivitar DVR480), but need to adjust azimuth down as it only caught Q-Tee at the top of a loop. This is definitely not a windy weather flier, but on a lazy summer day, would be a total blast especially with the generous tail control surfaces, might even catch a thermal.

1/2 oz (15 cc) Norvel CL mount tank gives decent flight lengths of about 7 or 8 minutes of flight time. The Cox .049 Black Widow had an 8 cc (0.27 oz) integral tank and correspondingly half the flight time. However, I'll need to add another vent pipe to the Norvel tank so I can stunt. The end of the vent is at the bottom of the tank, so tank acts as a Uniflow. But when seriously changing attitude (like in a loop) engine cuts out when vent is no longer submerged in fuel, changing venturi feed pressure. Solution is to drill an air tight hole at the bottom of tank and extend another brass vent tube to top of tank, so fuel is always at atmospheric pressures.
