I hand launched mine for over a year with no problems. Mine is just a tad bit heavier now so I don't hand launch it. I did add a steerable tail wheel with the retracts though.

Normally the gloves I buy are Large, so my hands aren't gigantic or anything and I can hand launch it fine.

I grab it from underneath behind the wing with my right hand. I use my ring finger and pinky underneath a bit to steady it with my thumb/pointer/middle gripping it from the sides.

I don't have anywhere to ROG but if I did I'd probably add a steerable tail wheel. From what I've heard, the rudder doesn't have much authority in the air since it is such a small area.

That is exactly how I hand launched mine sgf. There are a couple of issues with the steerable tail and rudder. One is (at least in my opinion) that the rudder is not very effective. I put it on mine at first when it was a belly flopper but it didn't seem to do much. Then when I rebuilt mine in to a bubble top with retracts, I added a steerable tail wheel but did not put the functioning rudder back on it.

I quickly found out the tail wheel didn't do much good without the rudder. The problem is that the first thing that happens with an ROG is that the tail comes up pretty quickly. Once the tail wheel is off the ground, without a rudder, you are back to having no steering until it's airborn enough that you can roll it with the ailerons. So, I added the rudder back on mine for that purpose only.

Here's a couple of pics of mine. You can see where the tail wheel is.

It's hard to believe that plane started as an E-Flite P-47!

That's a good thing to know about the tail wheel not being effective without the rudder.

Yep, with a little head scratching, a lot of work and some days with some choice words at it, it got converted. I recently got rid of the black canopy and changed out the cockpit too.

Hi Tom.
I must agree your P47 looks sweet. I will start to read this thread to find out how you achieved that smooth finish.

Thanks for the pics sgf323. Nice bike too.

Nice paint job on that jug Tom!! How did you work the retracts in that thing?

Anyway, I just got back from the field. The P-47 was the first thing I put up this morning. I took off from the ground. Once I got enough speed she went pretty straight. I noticed that at low running speeds she has a tendency to want to turn to the right. After messing with the motor mount yesterday and realizing she was on pretty tight, I decided to just put her up as is. I was thinking that the thrust angle was off, and that's what was causing her to turn to the right on roll out.

Anyway, she went up nice and smooth, but really nose heavy. That was something I was definitely not expecting!! I figured with the added clay in the kit, they were expecting it to be tail heavy. I gave her a little up trim, but not too much. She was still quite nose heavy. I brought her back down beautifully, and rechecked the CG...hard to do in 10mph winds standing in the open. I moved the battery back about an inch, and put her back up...AWESOME!!!! I love this bird! She had pretty tight rolls and her speed was right on the money (not too slow, not too fast). I ran two batteries through her before bringing her home. She deadsticks VERY WELL!!! I honestly don't think I could ask for better landing characteristics. She is an awesome fly all around!!

I want to thank everyone here in this thread for all the help, tips, suggestions and advice! Another reason I love it here at Wattflyer. You guys/gals are terrific, and I couldn't have asked for better friends. Thankyou!

Mike

Grasshopper:

I watched that thread closely and I've just started converting my old P47 to a bubble top as well. I'm going to paint her up like the one in the Udvar Hazey center. I haven't been posting a "build" thread cause' you pretty much covered everything. I will post some completed shots.

I am thinking about adding flaps as well... I even thought about tying them into the retract servo so I wouldn't have to add another servo... Gear down = flaps deployed. Gear up=flaps up... just a thought. Maybe use 1 full size servo for all.

Anyway, I love this bird. I've got one still setup for belly landing and hand launching and it is my daily flyer.

Pic from the museum below... thats the enola gay behind her.

That's a great looking jug Wilm. Please post some pictures as you go. Feel free to add them to my thread on the conversion if you don't want to start your own.

That's great news, Mike!
I'm happy for you. I'm also glad that my huntch was right about her being OK as is. We can still widen that cowl center hole out some if it needs it.

WE WANT VIDEO!!
Please disregard the fact that I could have been there with you if I had just rolled my lardbutt out of bed and met you there!

Thanks guys. Hey John, she seems ok. I don't think I need to widen the hole in the cowl, as the motor was never adjusted. I just went back out to give it another go, but the wind started scooting her while she was on the runway. I thought it would be better to just abort and fly another day.

I did however, fly the Intruder again. She handles the wind quite well, and my skills of flying her in the wind have improved quite a bit. I love it. Hopefully we can fly next weekend if you're not busy.

My neighbor took some videos of me flying last night. Here's a compilation of low passes. I've got a couple others I still need to upload.

Nice video sgf323!! What setup/powerplant are you using in her? I like that vertical she seems to be quite capable of! Nice job friend.

Park 450 w/ 12x6E. It pulls around 18amps peak at full power on a fully charged battery.

Are you using 3s 2000-2200mah?

Yeah, 3S 2100mah (although they bench test more around 1999mah)

I'm using the AFB3s1p2100 from this page. I've got 3 of these batteries and 2 E-Flite 2100's. I like the AFB best and the price is half what I paid for the E-Flite's!

Yeah, I use 3s 2200mah Li-pos in mine with the Park 450 and 25A ESC. I dunno, i checked the CG and it was right on, but then she flew so nose heavy...too heavy for comfort. I had to move the battery back and then the CG showed tail heavy, yet she flew just fine

Here's 3 videos tied together taken the night before the above pass compilation. The best video is probably around 4:40+ in this one. There's an awesome shot against the moon in it!

Tonight while flying I was practicing belly flop landing approaches. I would come in, drop throttle, sink down, then feed throttle and fly across the field at about shin height. One of the times I got a bit lower and when I pulled up I tail dragged it!!! It was a huge thrill!!!

I was at the LHS tonight and they still have (4) P-47 kits in stock. I'm surprised they still have any.
