Hope this flies |

Soooo,,,,,In had some time while the 550e was down for repairs and I some foam and hot glue laying around,
So I finally decided to give it a shot. I "read" mutliple threads on the web and decided to just go for it. It's a profile Yak 54 design I printed and slightly modified by Gene Bond from right here on RCG. Thanks Gene for your inspiration! This foamie is made of plain old dollar tree foam board and hot glue with some balsa thrown in for lateral strength. If this design works out I will try my hand with at least a thicker foam if not different type. I ran two balsa ailerons down either side of the fuse to add weight and strength. I don't want this thing floating all over the place and since it's my first build I kind of just want to see if I can hang with the scratch build boys and to see if it flies or not. If I remember to I'll try and bring a scale home from work tomorrow to get a more accurate AUW for power to weight ratio calculations. For now she is equipped with an Eflite 480, 30A ESC, and four DS76's leftover from multiple 450x heli rebuilds and probable powered by an 1800mAh pack. The power plant came from a PKZ P-51. I powered her up using the stock 9.5 x 7.5 prop and she was hovering at 3/4 throttle (hold then let go type test) with all the equipment hanging off. So I think this will be plenty of power. I still need to select a prop, add the control rods, run the wire, and check CG. As for CG, what's the recommendation here as far as locating it? Pics to follow tomorrow, She's ugly as can be, but she ain't in no beauty contest either. |

General thank you to everyone
Hello, this is my first ever post on RCG and over the past 2.5 years I have been flying, a lot of my info and help I have gotten has been from here. so, basically I just wanted to thank everyone, I can't really name names because there are so many of you who's contributions of info have helped. my first plane I built was a depron cessna 185 using all the techniques I have read about here, and I have to say I was amazed that it actually flew really well. 2 years and countless scratchbuilds and dollars spent on the expensive depron (The best foam I have found here in AUS) later, This is my latest plane. it has a wingspan of 3 metres (118 inches) and is powered by 2x hobbyking donkey 820kv, 60-70a esc and one 5000mah 4s, it has flaps, opening cargo door and 2 flour dropping tanks to give the effect of a smoke system (One in each engine mount) haven't flown it yet, but if all goes well should fly this weekend, without the help of all of you this plane I have build would not have been possible, so I'd just like to say Thankyou

Well, good news and bad news. Having trouble with my phone pics so I'm waiting to post those.
Good news is that I can definitely build a fly'able dollar tree foam profile plane. I learned a few things here and there for sure. Bad news is that she only flew for about 5 seconds before "landing". In an instant she got level flight but I forgot to dial in d/r. She rolled with the slightest stick movement. I could have gotten it under control, but by the time I had a chance to really get how she was going to react her wings folded up like a set of gull wing doors on a Delorean. More like star fighter from Star Wars actually, She stayed airborne and then took a hard nose dive. I' m sure I can fix her up, but wondering if another build wouldn't be just as easy. I can add in the things I learned from this go round. It took about 2 weeks of piddling and tinkering. I could probably have another ready in a week given the time......but my 550e takes it all up right now. Will post the pics as soon as I can. ...and nice build on the cargo... |

I would agree for the new build, I did 2 or 3 before i got a working system and quit doing stupid mistakes, once i forgot the ailerons were not plugged in, others were from not enough support in the structure, after flying the plane I noticed stress in certain areas, you'll end up with a model that looks as good as it flies and hopefully it'll last, sam .. |

Started planning for a thicker foam design that won't require as many strengthening "joints" as this 3/16" dollar tree foam. I could glue two pieces together for a solid 3/4" piece. That might work a bit better.
Having said that...I did make a couple small repairs and took it out to the field, as previous tests were done in the backyard. Not sure how I thought I was going to test fly a plane in such a small area. At the field however I was able to put 3/4 of a pack through it before I made a controlled landing. Video is uploading. It is still way nose heavy and takes an immediate dive when I let go of the sticks. Battery placement should fix that. Video uploading, as well. She rolls like a champ with only 50% d/r dialed in and is the rate I used in the video, I just have to get the pitching dialed out of her, transfer the design to a newer/stiffer board, and build it out. |

I thought that I had replied to this thread several months ago, but unfortunately I'm not finding my post. So here goes;
It's difficult to thank any single individual, for there have been so many along the way who have posted so many plans, ideas, tips and tricks to make my builds go a lot smoother. But, if I had to comment on some of these great people, here ya go. Balsa or Carbon, thank you for your valuable input on my projects that were inspired by you. I don't think that I could have advanced like I had without you. You continue to contribute your experience and knowledge (whether directly or indirectly), in ways that I can't describe, and I can't express my thanks enough for your generous, and humble contributions. Lee, thank you for your knowledge, and entertainment. You give great pointers on your builds, and I'm thoroughly amazed at what your aircraft is and can do (if this made any sense) . I too live in Utah and I love seeing your planes fly. Your planes are a blast to watch on video. Springer (among others), thank you for your input on setting up the controller (and the SAFE RX functions) for various programming on so many other planes. With out your input I'd probably still be on here (RCGroups) looking for answers. I have thoroughly enjoyed my DX6, thanks to all who have contributed your knowledge and expertise. Flite Test, thank you for your free plans and instructional videos with your most excellent tips and tricks. Although I've not used your plans to build anything, I do use them for references on dimensions and angles on my projects, plus great building ideas. Chuck T Seeker on the Apprentice S 15e review thread, your review is what got me back into the RC aircraft world in the first place. I chose the Apprentice S 15e RTF because of the reasonably affordable RTF package ($300.00, plus the larger size aircraft) that had gotten me back up in the air the quickest, and the easiest way, with a package that has helped me to regain my confidence in flying. I have had no one local to teach me how to fly, so I had to learn on my own. Despite my crashes and repairs, this plane is still a flying work of wonder. dz1fsb, thank you for your plans and your ongoing contributions. I thoroughly love your combat planes, especially the Corsair. Your tips help a project become a success. Of course, not to forget to include Dollar Tree for providing us with a great foam board for a great price! There has been so many projects that have been constructed from this one single product that may have not been as easily done with others products at such an affordably priced and is so readily available to most of us. There are so many others who I could thank, but I feel that the above mentioned were the ones who I have gained the most knowledge from. But, I do appreciate ALL who have contributed to this great forum. With out you, (newbies and experienced alike), I'd probably just still be tinkering on Jeeps and cars in my home garage. |
