The thrust angle change works, but.....


Really did it this time. This morning, took v2 fuse and v1 wing out with my best 460mah battery to test the increased down thrust. Was really foggy when I first got up, but I waited til the sky above was all blue, still some fog around, tho. Launched her and she began a 30 to 40degree climb. Nice and straight til I got up into what seemed to be wind the opposite of what I was seeing on the ground. Began circling, found what looked like lift, and was so caught up in that, that I didn't notice how high she was. (prob over a thousand ft looked like less than a quarter inch at arms length) and how far to the north she had drifted. Finally decided to bring her down and realized she was dropping into fog/haze, and a white plane looking at her nose in white haze is invisible. tried several things (not the full down ele/rt rudder I should have done immediately. But she seemed to be still climbing, or at least just staying at a level. Couldn't see well enough to keep a heading back to me. finally gave up, hit the elevator/rudder, but was invisible. Walked in the direction I last saw her, but found nothing. As high as she was, may have drifted a mile over woods, etc. Ah well, lesson learned, don't fly when you can't see the entire flying area. And, as one might expect, even though I recently put my name and phone # on all my planes, I hadn't added them to it yet! So, next version, the nose will be 90deg to top surf, not bottom. Course I need new motor, etc, etc.

That really stinks. I have only flown in foggy weather once and almost lost mine so I try not to do that. -Tyler

Actually it's kinda fun if you're close in and can just hold a heading, watching it fade in and out. But Way up there, Not a good idea. lesson learned. Ah well, today's my birthday, so last nite I ordered my bd present from Hobby King, motor, esc, batteries, servos. Already have the handiboard, Here comes V3, Polyhedral wing Like V1, little taller V stab, still from one sheet.

It's waaaaaaaaaaay more than you need! The whole plane less battery only weighs 6 oz. that motor will fly a 15 oz plane nicely. The only one close i saw on headsup site is this one: http://www.headsuprc.com/servlet/the...ort/Categories and it may be overkill if it's a hot wind. Watch the video on first page and you can see how fast the little c20 and a GWS 6x3 prop on 2s battery will pull her. not much drag, not much weight, and you don't want to blow the wings off her anyway. I don't think don has a combo, but I'm pretty sure you can get a c20 motor and 10-12amp esc from him for $20 or less. He's bz1mcr here on RCG and his site is strongrcmotors.com

I also just got a c20 motor from HobbyKing, and based on one flight think it's about the same as the ELE ones Don has, although the 24" blubaby I was flyin it with at the Indoor soccer arena got it's tail feathers knocked off in a midair collision on first flight, so I couldn't really wring it out.

Another comment, on the plans, if you print them, cut all the pieces out, and lay them on the Readiboard, you will be doing way more work than you need. You can just draw the lines on the board and cut. They are all straight lines, and all define edges of two or more parts.

Would a 24 gram 1500kv motor running on a 2 cell 360mah battery work good. I was useing it on a 3der but got frustated.
Thanks

I would think so, motor not much heavier. might need a larger prop, tho (the 2100 kv worked nice with the 6x3 prop) and it will move cg forward, so you might need to reposition the battery aft to compensate or shift the wing forward. You will have to play with it. Best flying CG on mine is about 25% aft of Wing LE and the LE is at 6" aft of the firewall.

Hello,

here is my start to my build. Gathering Materials. Well my wife went and got me some foam board (4 sheets) and some awesome orange. That awesome orange works great, like you said it would, to take the paper off. I also went and ordered my electronics (nothing on backorder this time) and i want you to look at them and tell me what you think.
Motor: https://www.hobbyking.com/hobbycity/s...runner__1200kv
ESC: https://www.hobbyking.com/hobbycity/s...ies_18-20A_ESC
Servos: https://www.hobbyking.com/hobbycity/s...co_Micro_Servo
Prop Blades:https://www.hobbyking.com/hobbycity/s...H/229mm_(1_set)
Prop Hub: https://www.hobbyking.com/hobbycity/s..._/_3.0mm_shaft
Battery: https://www.hobbyking.com/hobbycity/s..._20C_Lipo_Pack

I hope i did alright. I think i did but i really dont know that much. I tried to go as cheap as possible on everything except the prop and went with little bigger battery. I also purchased a couple extra servos because my friend wants me to build one for him to high start. But that only added a couple of bucks. Soo anyone looking to build a cheap plane my electronics came to $52 with shipping (and three extra servos). the four sheets plus awesome orange was $5 and some change so right now im a little over 57 vested. I need dowels, tape, glue, and sharpies. I have an old credit card lying around. I figure $10 more in materials and im ready to get started.

You know springer if you looked at your plane from a beginners view. Some who has never flown before could build the plane, buy the gear and the 4 ch tx/rx, buy the $11 turnigy charger, buy some rechargeable batteries from wal-mart for radio and have a SOLO setup for around or even under $100 if they shopped hard. This could be the most inexpensive door into rc planes in the world. Im impressed. No rtf or arf can come close to touching that.

Yeah i looked into cd rom motors and your right there a little out of my league but i do want to try it in the future. My dad has a wood mizer and alot of Basswood that he cut and has lying around. He was going to use it for modeling and other hobbies but he hasnt gotten around to it ill try to take some of that. I think i can do a good job on this foam with sharpies so ill try that. i was sceptical about sharpies because ive seen epp done with sharpies and i think the foam is too pourous to get a good coat. But this foam seems smooth so it should work fine. Well i hope to get the rest of the materials tomorrow after work, but maybe not because of new years eve.

101: The 2822 is a great motor(even more so at the HK price!) but it's way more than you need for the glider. It'll fly a 42" BluBaby that weighs close to a pound as fast as I ever want, and it'll swing a 10x8gws prop. Check this video for how it will fly: https://www.rcgroups.com/forums/show...t=aileron+wing I bought this motor for my version 3 glider: https://www.hobbyking.com/hobbycity/s...trunner_2300kv (although it's on a 24" BluBaby right now, couldn't resist!)
Guess I should have posted the links for the recommended setup, sorry. But the 2822 will be great on your next plane! The speed control is perfect for the 2822, but you will only need a 10 amper for the 20gm motor: https://www.hobbyking.com/hobbycity/s...ries_8-10A_ESC

The servos will work fine, but you could go as low as the 3.7gm servos (had them on the one I lost and they worked well) Another option is the 5gm Hextronix, they are a bit smaller then the 9gm Hextronix and Turnigy ones. The ones you got will transfer to a larger plane better than the small servos.

The blades and prop hub are a good fit for the 2822, but will look really large on the nose of the plane. it's only 1 by 1 3/8". For the smaller motor, this prop is a good one: https://www.hobbyking.com/hobbycity/s...6mm)_(6pcs/set)
You'll note that the smaller motor comes with a propsaver and a collet type bullet nose mount. Use the propsaver with the dd-6030props.
Unfortunately, same thing goes for the battery, It's a good choice for the 2822, but I don't think it will fit inside the fuse of the glider. You did a great job of picking gear for a 42" bluBaby! Should be your next plane! I would suggest this battery for the glider: https://www.hobbyking.com/hobbycity/s...0C_Lipoly_Pack Or this turnigy one: https://www.hobbyking.com/hobbycity/s..._20C_Lipo_Pack Looks like both are out of stock, tho. Any battery in the 500 to 800 2s will probably fit in the fuse. 3s packs may be too wide to fit. And you aren't looking for speed, but duration for when you have to search for those thermals.

If you are going to make a version for high start, you will probably want to reinforce the wings more, maybe a larger dowell in the leading edge or for sure a reinforcement at the centerline joint. The high loads on the wings when they are released may fold these. The basic design is an attempt at lightest weight, so there's not a lot of reinforcing anywhere. It'll handle it's own weight even in a crash, but I'm not sure about the forces of a high start. But hey, thats the fun of scratch building, trying something new, and after all it's only foam, the easiest modeling material to repair! Gorilla glue and hot melt are our friends!
