Continuing from part 1, I select an engine and attempt to fly my scratch-built Q-Tee. See part 1 here: • Q-Tee Build Part 1 - W... ------------------- Facebook: / hobbyview Podcast: rcroundtable.com/ Instagram: / hobbyfitz
I love the plane and subject matter as an avid cox fan, but I'm mainly commenting to complement your editing and production- You showed just enough without showing any padding, for example, the shot of the glue and the balsa going in for the servo mount was perfect- here's the glue, the wood, ding, there it is all done. Great pacing and narration. Instant sub!
Brought back memories, from the mid sixties before I was tainted by r/c😂. I must locate a muffler or two to keep the neighbors at bay. Thanks for posting
No fast forwards no background music fantastic commentary make s fantastic video with out dying of boredom sir keep up with what you are doing this is entertainment and learning at its best Greg
Couple things, Cox reed valve engines will gunk up the fuel pickup and needle orifice in the tank, you need to take it apart and clean it out if it's been sitting for a long time. Plan your power installation before gluing on the bottom sheet behind the firewall, drill the mounting screw holes in the firewall and install T-nuts, makes it a lot easier to R&R the engine plus the wood screws will oil soak and strip out eventually. Cox TD and the Norvel should be the same mount screw dimensions, at least it is on mine. Make the bottom sheet removeable to R&R a 1 oz. tank and access the radio battery, I use a 35mm film container with the fuel line inside a rubber balloon inside the container, so you do need to have easy access to change the balloon when it gets wasted from the fuel. The throttle sleeve can be adjusted by sliding the C-clip around on the sleeve to adjust idle, final thing, nice Q-tee they fly good.
For those who don't know, you can drill a small hole in the side of the fuel tank and run a fuel line to a 1 ounce fuel tank. My dad and I built several Q-Tees. We used .049 black widows and td .051's. Fly around 10 minutes then climb and climb and climb until out of fuel. Then catch a thermal or ywo
My Dad learned rc flying on a q-tee about 50 years ago, and of course he got me into the hobby, thank you for this video it really brought back memory's of the old days!
I never had great luck with those engines especially without cox fuel. But when they did run I had a blast! Thanks for this build and video. Brought back some fond memories
Very interesting. It's fun to watch the rebirth of a great model from almost 40 years ago. It flies great, just like the one I built and learned on when I was half the age I am now. Thanks for the memories.
I just came across your videos of building and flying the QT. Thanks for creating and sharing the videos and for the memories they triggered. The first RC model that I flew was a Jr. Falcon ~1971. It was "controlled" with an EK Logictrol pulse system using just the Rand rudder actuator, and was powered by a Baby Bee. Your QT looks and flies great! Nice job and thanks again.
The reed sticks when they are laid up for a while, that's why they will run on a prime but not continuously. Sometimes you can cure it by sloshing lots of fuel through the engine without stripping it down, but if really bad you need to tear it down to get at it.
Thanks for the build vid. I'm glad I ran into this. Got love the old school fuel planes. I grew up with my 049s. Built a few for sure. Your plane flew great. Nice job on the plane itself too. Don't you just love how they look before you cover them.
Before replacing the glow head on the "baby bee", disassemble it and clean it thoroughly. I seem to recall that the way your engine runs was commonly caused by a stuck or damaged reed valve. I believe there is a screen located behind the reed valve that could be clogged with residue, that should be cleaned, and finally I also seem to recall that there is a small length of fuel tubing in the fuel tank. If it has deteriorated, or fallen off, it might also be the cause of your engine not running past the prime.
Yes, that is possible. I'm pretty sure I had cleaned the Reed valve, but it may have gotten damaged in the process. The reason I mentioned the glow head is that it also stopped running off of the prime as well.
I agree with you kwbarnes1 You hit the nail on the head on all points. I got my first BabeBee around 1957 and have had several including the GoldenBee I think it was called (had larger tank). I also had (pretty sure) a throttled .049 on an RC foam motorized glider around 1978 (with a Futaba transmitter). I still have a couple (I think) and an .020 You know, I have started that .020 in my hand. Notice I said 'started' - they get hot. Oh, to the host here, on that reed inside, it has to spin freely. I can't tell you how many times I have had to disassemble them, take that retainer clip out and found a piece of grit or grass under the brass reed.
I had one of these as a teenager, one of the most fun to fly little planes. It'd make a great park flyer with a 3S 1300 and 1kv or so outrunner. Tempted to build one.
I had one of these, too. Someone gave it to me after they unsuccessfully built it and tried to use it as a trainer with no instructor. I crashed it a couple of times, but eventually got the hang of it and I enjoyed it until the .049 wouldn’t run any longer. I have a NOS .15 that needs a home... I’ve been thinking of a bigger version of this plane as a scratch build. Thanks for the video!
I got used to the castor oil mess on my models, then converted to brushless. Going back to glow engines now because I miss the sounds and smell of the fuel. I think a pusher configeration would solve the oil soaking issue? My first era (controline, freeflight) were powered by the OK Cub .049 salvaged from a short lived plastic Tri-Pacer U-control dad got us for chrismas, 1959. Stepped up to a Fox .07, then found the Baby Bees were the ticket. Would love to have a collection of those ole fuel cans by Cox Fox (MissileMist!) etc.
Hi! Never seen this 1/2A scale airplane before at my place but it seems to fly perfectly well ! And I am about your age, I guess so I have, just like you, the nostalgia of these kinds of small scale models. May be more than Guillow's models because of their prices and because of, sometimes, the balsa wood level quality, not at the top! Anyway, I will try to provide for myself this airplane ! I have an AP .061 engine which I'm sure can be suitable to this plane. And with a real carb and throttle control. Keep in touch and, sorry for my english ! Best regards from "Mike " from France !
Cool.. I had an S-Tee, the shoulder wing version. My plane didn't fly that well, seemed to be under powered with an .049. In any case, great to see an "old" design fly again!
Brilliant videos part one and two. Just love this little thing. Within 24 hrs I have got the plans and ordered a Cox 049 with props etc etc. Guess I'm hooked! Pete
I actually had one of these back in the early 70's. It was a real two channel FM radio and 049 motor out of a crashed Cox Cessna 210 Centurion. It was way too small and fast for me and I crashed it after a couple flights. I ended up getting a 4 channel Futaba, and OS20 and an H-Ray kit that Christmas. Then the RC bug really took off. I would love to get a short kit and build another one now that I know how to fly. LOL
Recently, I just found your channel by chance. I build and fly quads from time-to-time but you do such a great job with your videos that you got me thinking I'd like to try fixed-wing. Keep up the great work. I'll be sure to follow you.
Hello guys very good excellent I loved it. I send a big greeting for everyone from the club grouping model Albatross Albatros of Buenos Aires Argentina 👋😎
Love it Fitz! I too grew up on Cox engines on all sorts of vehicles. It's a very fond set of memories and a great creativity inspiration, mechanical aptitude builder and problem solving set of skills I cherish to have had the opportunity to get. Most kids these days are scared little narcissistic, unambitious, uninformed automatons. Its pretty sad to see.
I know this is now a few years on there is a cox parts dealer out of canada that sells conversion heads to use a normal glow plug in these engines. I picked one up to try in an AP wasp once things warm up and I feel like tinkering outside again.
I flew my QTee in 1979. Crash and burn in first flight. 2nd flight in 1981 was a little better....yet crashed. I got proficient after college. Electrics make the difference now.
I taught myself to fly with a Q-Tee back in 1990. I put 200 hundred flights on it with a Babe Bee engine. I knew if I kept counting past 200 I'd probably crash, just because I was counting. So I gave it to a friend. I have no idea how many flights he put on it. I recently built another from scratch.
I'm guessing you had a cox 0.049 on a helicopter LMH-100? I was test pilot during development of that machine in the early 1990s. I also flew for promotional videos. Fun times.
A very awesome job on the 2 part build and flight videos congrats on the maiden as well I never was able to try out the throttle ring 049 engines sadly where I fly at 049 engines are a big no,no, lol. BTW I love those voice overs you do in these videos it makes it feel like those older tv doc's from the 70's&80's like ''In Search of'' or''Ripley's Believe it or Not'' LOL
I enjoyed your video. I happen to have a short kit of the Q-Tee awaiting it's turn to be built. But I am done with Cox .049 engines and wondering if I can continue finger flipping the prop until it starts. Mine will be powered with a brushless speed 400 electric motor and a 3 cell 850 ma lipo.
Hello... what a walk down memory lane. I flew the heck out of my Q-tee back when I was 12 years old, nack in the mid 70s. I want to build 3 of them (one each for my 6 and 8 year old boys and one for myself). I have access to a laser printer. Do you have the file you can share??? Thank you fo rthe video!!!
there is a possible Reason why the controls are sensitive: distribution of mass. this is related to, but Separate from, Balancing. you may know that when a box-fuselage design is used, unless appropriate steps are taken, there Will be excess mass in the tail boom. those steps are - mass-reducing CUTOUTs at the tail boom and the use of two or three FORMERS, in the construction; so that structural strength is not compromised. googletranslate www.modelairplanenews.com/wp-content/uploads/2013/03/3-Fuse-Framed-rearview-web.jpg
thanks for posting. for a gas-powered application, servo installation Should include the use of rubber grommets; for vibration damping. this is true because the position sensing mechanism inside a servo, will tolerate only so much vibration. googletranslate
Good flight, the .049 Tee Dee really brings out the performance. Before my last Figure-9, a Norvel .061 Big Mig similarly made the Q-Tee into a nice sport performer with a touch more wind penetration than my Golden Bee. Good review video!
this is a great video, I want to build a plane with a cox engine, I'm collecting parts and engines just don't know what plane I want to go with, probably a Q Tee style one or something else form Willy Nillies.
Great videos, I especially enjoy your narration. I now have a peek interest in the hobby . Do you have a suggestion for a good beginner electric trainer that not too expensive. Thanks in advance .
It is a great pity these motors are so high pitched but guess that may be because of the Nitromethane in the fuel. One day will get around to converting mine to electric (if I can de-oil it). Thanks for the series.
