How many servo's will it take to run the snow blower from the house[sm=lol.gif]

Why would I want to do that? The wife does a good enough job with it.[8D]

MAN, I hope she's not looking over your shoulder. You may be riding that blower with it strategically placed in a certain body cavity.

I just noticed that you have some glue over the top of the canopy magnets, that's a no no. If there's a gap between the magnets the holding power is way down. You want metal to metal for the best holding.
I scraped off the excess. Better but still not strong enought for me to trust in the air. I can almost pick up the fuse by the canopy before it pops off, but it does pop off. I'll keep going, when it take a pry bar to pop off then I'll feel safe. And I can always put a screw in the settle the matter.

I'm done.

I installed the switch in front of the wheel well and am using whiskers to turn it on and off. I put the charging jack in the hole they want you to use for the rubber band, I'm going to tape the wings on.

I've got it balanced at 75 mm from the LE, that works out to just behind the back of the wing rod.

I tape the canopy on, it should not need to be opened.

Hey, that's a nice clean finish. For all those following our builds you should be able to see the differance between someone who followed instructions and someone with experiance.

I did a little graphics work. The numbers are 2". I had them laying around. Would go smaller if I was to buy them new maybe 1 1/2". The graphics that came with my kit aren't that great. I used a few of them for the "look" but dont expect them to stay on for long.


P.S. My gal likes the run the snow blower, but not on the storm of the year.

Nice job guys. I was considering one of these ships but decided against it. Not enough experience yet.

RE the snow: We had our storm of the year on Friday. 2" if we were lucky. It had about the same effect as this storm on you guys in the NE though. The Southerners just can't drive on the white stuff. May the RC gods be with you and your new "birds."

Nice snowball, on my end I couldn't believe she found her Xmas stuffed bone (favorite this month)


#2 lead shot is on it's way. I needed to make up some weight bags for the new project, it's has some complex sheeting. Figure I'll use what's left over for the 4m.


P.S. After seeing how Rich finished off his canopy, I now wish I hadn't glued the silly inner piece in. Live & learn

Now I have to test fly it, go away snow! I may go to Penilles Park, Fla. in two weeks, I'll take it with me.

Having someone to try to keep pace with really helped the build. I cleaned off the workbench today, I'm going to make a mold for a flying wings fuse, I'm having a tough time getting started, I just want to veg out. Maybe I need to start a mold thread so I stay on track.

The Discus is still under construction, and I have added a main wheel. The elevator servo is mounted on servo tape, AND mounting blocks epoxied into the fin.

Dr D let usknow how it's going. Also, have you heard anything about the tow Ned B is involved with?

Rich, if you start the mold thread let me know. I still have to figure out how to stuff this bird into my wagon

Hello Gentlemen,
I've found this thread very helpful. On the Elevator I installed a pull-pull set-up with the servo in the front. Has worked well.
I need help. My wing rod was lost. Does anybody either have one available or a source to purchase a metal or carbon ne. Plans say 10mm? X 500mm. I measured daim 7/16. Is that correct.
My first flight is on hold until I get the wing rod.

Thanks for the help,
Maj Tom

I miked it to 10 mm, by about 21 inches, (i'm not a metric kind of guy). I said about 21inchs because once you get it in, it stays in.

I broke a canopy on the 102 incher and asked yuejin2002 if they had replacements and he said yes, so you could probably get a rod there.


http://www.mcmaster.com/ has it for $6.31 for 36 inchs Part #88625K69

I think the way to go IS electrifying it, It probably doesn't add ANY weight to it at all, mine took two pounds of lead, which seems the normal amount to get a balanced plane, it might as well be an electric motor and battery!
Have you flown yours yet? Mine's been waiting for a clamer day for weeks, the one good day I couldn't play![:@]

Hi Rich, No I have not flown mine yet. Same problem as you. The weather here in Ohio is just now starting to warm up above freezing. A couple of years ago I had a 3-meter electric glider that was was a lot of fun to fly. It had a Jeti 30-3 swinging a 11/6 prop on 13 round cells.
I figured this 12 footer is going to need 800-1000 watts. I got a used Aveox f12 motor that will swing a 14/9 folding prop on 13 cells x2.
I still don't know how I will launch it. At 10 lbs I doubt I could hand launch . I am thinking about a bungee launch with 30lbs of pull.
Hopefully that will get it up to flying speed in under 20 feet and soon after hit the throttle. The power system weighs in @ slightly less than 3lbs. I hope to post some outdoor pics soon and hopefully a successful first flight report too!

Rich and Tom,
Thanks so much. Your both are life savers; in an RC kind of way. I ordered both the $6.31 and the $11.32 10mm rod because I'm not sure which is stronger? They both used different lingo so better safe than sorry. Do either of you know which is stronger? When I bought the 4m Discus I'd also intended to convert to electric. The day prior to the nose coming off some guys at the club announced they would be aerotowing. They did it the other day and what a blast.
Tom,
I'm in Cincy also. Infact we have a mutual friend, Carl Tulanko. Didn't you get to fly his HET F-20. What an EDF!!! I have the HET F-18 and love it. My club is the Loveland PropBusters located at East Fork Lake Park. We plan on flying several sailplanes on Saturday wx permitting. Give me a shout if you'd like a heads up to come out.
Again guys thanks for the info. I was'nt happy with the lose of the wing rod.
Thanks,
Tom

Ok on getting the rods. I'm not sure which would be best. I think the strength on either would exceed the wings survivability. The thing about Mcmasters is they have so much stuff and from different vendors that you could easily end up with different prices for the exact same product.
Yes I got to fly Carls Tigershark. It was very well behaved. I have the F-18 also. Its a great fly-er. I checked out you clubs website, it looks like a very nice setup. We will have to come to your Funfly. By the way, check out the Hawks webpage http://www.hawksrc.org/Main.asp We are going to have some great events this year (3 different types of funflys) all with worthwhile prizes.

Good luck and great lift

Back from a couple of crazy weeks at work. Rich are planning any time for a maiden flight? If so let me know, it would be worth a trip to join you. If time allows I going back in to add a wheel and winch tow hook. Should have do it from the start.

Does anybody know the Renny 2M E II? A bunch of guys around here are going for them.

I almost test flew it today. I thought I would be the only one at the field, so I left it at home[:@], I want some one to hold it for a ground takeoff, so I can have both hands on the radio for the first flight. When I got the field my friend was there with bad news, we aren't allowed to fly there anymore[>:] the soccer season started, they play on weekends, we fly on weekdays, makes since to me.[sm=spinnyeyes.gif] We may get to fly at the old Bell Labs site which is near by, so there's hope. I'll keep you informed.

You said let you know about my mold thread, I've built the molds, layed up a fuse last night, ( first pancake goes to the dog), when I post the thread I'll let you know, it'll be soon.

I'll be looking forward to see how the dog liked it.

I should have the Discus back on the bench to wrap up details this weekend.

Does any body have an opinion on RX batteries? I picked up a 6v 3200mAh 5 cell pack at WRAM. I wonder if it will be to much for a Hitech RX driving 7 servos. I hoping with this pack and 1 1/2lbs of lead to balance things up.

ANy help, well, will help!
