Tom, that plane is definitely worth rebuilding and a story on "fixes" will be hugely valuable to the generation that did not grow up putting sticks together themselves. So, in short, hated to see her go in but all is not lost.

[@marinjeam]

Very honest view back. Perfect maiden until the last laps.Not a lot of us will admit a pilot failure ;) Nice plane, good luck with the rebuild

[@oneskyrc9182]

Thanks for another great video. Appreciate the honesty and telling people the good and the bad. Look forward to the "repairing a crashed plane"video .

[@FAA-DPE]

I love that you posted this video and weren't like others who only upload their perfect flights this is the only way we can learn I'm your age and been flying RC just as long and yes I still crash.

[@flyingrcdotnet]

Well, stay tuned. I sort of did it again... But, now I can say it was just for you!

[@jamesnorth1063]

I really enjoyed the narrative. Tips about flying at 1/2 to 3/4 throttle and ballooning with throttle and flaps were very helpful. I've made so many mistakes flying that it's really nice to pick up a tip or two for free. Keep up the good work.

[@I_am_archie]

I just threw everything needed into the cart to build this plane. Thinking I'll go with the same engine you did.

[@JOSHFLYBOY007]

I had been waiting to see this video. The honesty about how the hobby can be a kick in the pants on the first flight is good to show. Looking forward to your video of the repairs!! Great info as always!

[@easystar123]

Hi there, I love all your RC Plane videos. She describe and explain everything so well and that's what makes them so interesting. I also like your honesty. Well done and keep up the good work.

[@organgrind]

Very sorry to see this happen but like others I do really value your honesty, and yes I'm very keen to hear that engine. I myself have ended up feeling that flaps, or flaperons, are what you employ when there is NOT any wind to reduce your groundspeed. Anyway, good luck with the repairs. I think that your KZbin oeuvre is the best, by far, in the hobby.

[@alajeunesse254]

Looking at this for my first non foam airframe and have been excited to see you get it flying. Bummer about the crash but I'm really looking forward to your videos repairing it!

[@flyingrcdotnet]

The fix is in progress. I do everything here on my own so it takes a while.....but it shall fly again! (in less wind and the video posted here!)

[@Bob-h1w3q]

Bummer! It is a pretty plane!

[@scottthompson2481]

How annoying , but on the up side we get to learn from a craftsmen like you , how to go about repairing a proper plane , all the best , Scott .........

[@bogey19018]

That is one of the fun parts of the hobby. Rebuilding.

[@TheMarcellToth]

The same thing happened whit mine Valiant mine has a Saito FA-82 GK but fortunately I was very high up so I was able to pull it up just in time.

[@sadierun1795]

We have all done the same thing. It’s nice plane

[@darkhorsegarage9623]

I like to mix my flaps with the throttle. Flip a switch and as the throttle is moved to a lower setting the flaps begin to deploy. If trouble comes I just advance the throttle and the flaps retract . Simple and effective. I also have a separate flap switch with two positions.

[@user-zx1ir7jt4c]

Tom you have an awesome voice! lol, I know it resembles some actor or celebrity? maybe? I can't exactly put my finger on who it is but it's there somewhere!

[@oneskyrc9182]

My channel sucks compared to this one but I want to point out just how much WORK his into a vid like this . If you watched a few mins or the whole thing , at least hit the thumbs up ! We all appreciate it .

[@jarrett1890]

Very well done video.

[@8311XHT]

Ouch. Good cure for a heart-breaking crash is a quick rebuild if possible. I can one-up you on things stupid;About twenty five years ago I crashed a Great Planes trainer on take off because I forgot to extend the radio antenna. Had it repaired and flying in about two days.

[@user-zx1ir7jt4c]

I just bought this plane and I'm thinking about just getting all the suggested components that they suggest because I don't know much about this stuff. Should I get anything different? I am actually thinking about going with the Saito 4 stroke motor since I can't find any 2 strokes...

[@nealjag3917]

the same thing happened to me to thats the hobby I still love it

[@daveb572]

Great video. Sorry about the crash, though. I just bought one. I'm putting a RCGF 10cc on the nose and the radio's going to be Taranis 16 ch tray style. I know, I don't need all 16 channels. LOL There's one issue I found with the wings. I wonder if you experienced the same issue during your build. It appears that the right wing flap servo cover had the covering put on the back side of the hatch causing a 1.5 inch mismatch between the two hatches. The ailerons are correct. I'll be talking with Tower Hobbies about it tomorrow if they're not off for the holiday.

[@flyingrcdotnet]

We did not have that issue. I expect that when you make so many of anything, there will be a mistake or two get through no matter what kind of quality control you have. This is the kind of thing that brings out the creativity in RC'rs.

[@WINDY7C]

Tom, I felt so sorry for you. I was watching the video and it was almost like watching a pre-view of things to come for my Valiant 10cc. I noticed the balloon when you selected full flaps, and wondered if you had programed in flap to aileron trim compensation? I didn't see anything in the Hanger 9 manual about it, however I am flying an E-Flite Valiant and that manual specifies 3% down elevator for take-off flaps and 5% for landing flaps. I thought that might be a bit small, but it works fine. The E-Flight flaps are not sloted, if that makes a difference. I am also flying a somewhat modified Timber with slotted flaps and leading edge slats. The factory settings for that are 9% and 13% respectively. I have just about doubled that, probably due to the modifications I made. In summary Tom, I think you only really made one mistake and that was doing a maiden on a gusty day. I am still trying to get the O.S. GG10 to idle down to where I think I can land it. I ordered a Sullivan Glo-Driver, maybe that will help.

[@flyingrcdotnet]

My 10cc Valiant ballooned like that because it was just going a bit too fast when I hit the flap switch. It comes right back as the speed bleeds off. I might program some elevator into the flaps but will wait for a calm day to figure out what this Valiant wants.

[@WINDY7C]

Thanks, I'll remember not to do that if I ever get mine airborne. I wis I had seen your video before I mounted my engine. It would have made it easier, and probably more accurate, too. Keeep up the good work.

[@jcarlosnegrete]

Great vid!. Im building that plane I really liked the foami version. Just one question, in the video you said you turned it downwind, but did you turned at the end or it tipstalled?. Do you think it could have flew out by just adding throttle?. Thanks and congrats for the channel, great content!

[@johnjohn4237]

Ive been waiting for this maiden video for a few weeks now, when I saw the title I didn't want to believe it... I just picked up a 10cc Valiant 4 Hitec D625 wide voltage servos for ELE,RUD, and AIL- throttle and flaps yet to be determined. Never felt 10cc gas would be quite enough for this plane for the type of flying I do, thinking about an ASP 90 glow swinging a wood 14x6. I really wanted to see you fly it on the NGH 9cc, I have the 17cc NGH but just too much for this airframe. Man!... hated to see that...but I know this is part of the hobby. This will be my first plane with flaps and was almost thinking about deleting them. Anyway hope the rebuild goes well... BTW what size prop were you running on the 9cc NGH? Thanks, big fan of your R/C BUILD AND FLIGHT VIDEOS...

[@MrJcosenza79]

I like your videos sir, what would be a good inexpensive service for this please thank you (valiant 10cc)

[@MrJcosenza79]

Servos!!

[@flyingrcdotnet]

I have been using HiTec servos for years with very good results. Check servocity.com who has a big list of HiTecs with their torques so you can choose the best one for your plane and budget.

[@RyaReddy]

Hey Tom, I have an 10cc valiant. Due to very limited choices in europe i put in an OS-GGT15 with 13x8 prop. Now after 12 flights the horizontal stabilizer broke, elevator on right side metal rod broke out completely. Mid flight it sounded realy scarry. Luckaly i landed safely. To your oppinion is the 15CC petrol engine just to much for this airframe? I have unlimited vertical even with undersized prop. Thanks for your simple short and informative vids.

[@flyingrcdotnet]

It sounds like you had a flutter which can easily be induced by too much speed for the airframe design. The 15 probably is too much engine but with throttle management you can stay out of the over speed stuff. Modern engines are developing more power than we sometimes expect so we need to think twice about "over engining" a plane!

[@RyaReddy]

@@flyingrcdotnet Just an update, bought and fitted an Saito FG11C engine. Runs and flies so smooth now. horizontal stabiliser was broken on both sides. Now repaired and installed carbon strips to prevent further flutter. Enjoyed couple of flights using 100ml in 20 minutes or so. Now the OS GGT is just a very expensive paperweight. Thnx and happy landings.

[@leonardodigirolamo5334]

Where did you get the power source for the Ignintion and the cut off switch cause Im putting a Valiant 9cc together as we speak or E-mail, Thanks

[@flyingrcdotnet]

www.flyingrc.net/techaeroibec.html I've been using these for years. Simple, works great.

[@williamlavigne7605]

Tom, I built the Valiant 10cc like yours with same engine installed. That engine is a pain. How did you ever get it to run right? I been trying to get mine running right. The manual is hard to figure out. Would like to know the secret.

[@flyingrcdotnet]

Small engines have always been a pain for me also. We spent some time tweaking the carb to find what it liked best. I think I will go electric in place of smaller gas engines, just my preference to get away from the tuning issues.

[@williamlavigne7605]

@@flyingrcdotnet Thanks Tom

[@kevelliott]

There's a lesson in there for full-size pilots too.

[@wadezinsmeister2350]

I'm putting one of these together now. I'm to the point of mounting a 15cc EVO engine and was wondering what type of battery and switch set-up are you using for your 10cc Valiant? MY LHS suggested using NiMh batteries but I've heard its better to go with LiFe batteries. What's your opinion? Thanks

[@flyingrcdotnet]

I used a simple Spektrum 3 wire switch controlling a 7.4V, 5000mAh LiPo pack. It probably doesn't need 5000mAh but I use them a lot so have them laying there. I know people will kick about the LiPo battery but I buy good quality packs (Glacier brand from Anderson RC, NC) and use a good charger and slow charge rates. Never had an issue.

[@prabukengg]

Hi, I have mistakenly reset my low speed needle,can anyone send me low speed neelde depth from opening,factory recommended 4.25 turns reset is not working.

[@MLS7012]

Can someone please help me on the sweet spot for the cg? The range is 63.5 to 82.5 mm...I'm also running a 15cc gas motor

[@bigeclipse718]

I'm about to buy this model. What motor did you go with and how does it fit? Is it too big for the cowl?

[@gpxrp7520]

are you using as3x

[@ManAndMachine23]

No it does not look like he was,as3x is good but it would not have saved this mistake...

[@eugeniominella]

Che peccato.... però fa parte del gioco. Tutto cio che sale scende

D'oh!

[@sonex413]

Thanks for the upload. Subscribed and invite you to sub back! Sad to see a maiden go bad, but as my buddy Richie says, "Part of the hobby......". Good luck w/the rebuild! Mike in Western Mass

[@rtoebak76]

That was all on you, but hey things happen.

[@johnfaustus1]

2:14 It's rare to see Tom wearing pants.

[@flyingrcdotnet]

Hey! The eyes are up here!

[@jo2lovid]

Tip stalls suck big time!

[@jhue73]

dang i hate that happen to you, that really sucks. thats why i hate flaps. it will stall some planes very easily, except my great planes cherokee it doesnt want to slow down even with flaps.

[@joeyjacildone4500]

woooooow nice lol

[@darrinboadway]

nooooo......

[@PaulDoodes]

That's a shame.
