As I got more into working on this body, it became quite clear to me that the old interior was not going to be usable at all. The answer was to reinstall it so that the cockpit didn't look so silly when you looked into it. Although devoid of the co-pilots collective stick (broken in the crash) and the cyclic sticks (they can be used in the new cockpit), there is still the main collective and circuit breaker panel along with the seats. I had a third figure that I bought (originally was a pilot) but felt that he was not as good a figure as the ones I did use. He looks just fine in this one. There are so many things that will never be used on the new helicopter, I might as well have left things the way they were but I had to find that out in the process of building the new body. When I get the new body done, there will be new glass for this one. Here are the shots from today's work. Have a great weekend.

Looks great Don! I really like the miniguns and the pilot isn't bad at all. I never thought I'd see her in the air again after the crash at HSM last year.

Thanks Barry:

It was not until I got it home and stripped out the mechanics that I realized that the damage was limited to some superficial gouges to the doghouse, the broken canopy, smashed TOW launcher, along with the struts, main gear, head, blades, and main shaft. Even the tail blades were intact and the worst damage to the tail was the elongated holes in the vertical tail. Naturally, all wires were ripped out in the tail but that was not horrible and was an easy fix. There are no lights in this body and that will be kept for the new one. I will certainly have this body with me at HSM but I have doubts the other will be done in time. The new one will need Callie's graphics to get it done or I will be stymied with the unit insignia that uses white. The rest will be doable. Take care and see you in the fall.

I have been slowly getting this helicopter back into some form of shape for flying this summer. Most of my efforts are in the flying of it right now but I am working on some aerobatics with the main one I am concentrating on being pedal turns. Why? Well according to some of the main scale events requirements is that you do a clearing turn (pedal turn) upon take-off. Sounds easy but in fact, it is a fairly precision requirement and it takes a very well setup helicopter to allow you, the pilot, to pull it off. Balance is the key component and there is also a bit of compromising to be done to allow for better forward flight.

If you have your helicopter setup for balance on the main shaft, reports are that the flight will look something like a porpoise in the water and so far, mine are not anything like that. 3D helicopters are normally set so that the balance is right at the main shaft which allows better flight dynamics for their stick banging moves. When I flew this helicopter last year, it was anything but setup for 3D and flew extremely well. As I have removed a lot of the old interior and replaced it or put some new stuff on (M134's for example), the balance changed and continued to do so until today.

I had placed a 6s 5000mAH pack on the weapons officer's side when I first took it off this year. As I added some of the old interior back in and then another figure I had, I changed the 5000 to a 3300mAH pack. I had added a lot of lead and Hysol to the exhaust cone to balance out the old interior setup and with the large battery in front, I felt that the lead should come out. I got that done yesterday and after repairing the damage from removing it, I went to balance the helicopter and found that the 3300 pack was no longer needed. So in effect, I have removed way more than two pounds from the helicopter. If I leave this along and fly it this summer as it is, this is balanced just ahead of the main shaft. that should be a lot better than before. In fact, I may have had too much tail weight, even with the battery in place but the nose-down attitude with the battery in and the lead gone was quite pronounced. I am hoping that later in the week or on the weekend, I can get this out and start to put a flight routine together. Take care.

man thats some fantastic work there !!

just a thought here, you could have given it a V-tail and use a 4 blade head to make it a 500C, you don't see many C models being built

Thanks. Although the "V" tail is my favourite version of the 369/500, this one has kind of grown on me. I think once you see the second body finally finished, you might agree. Take care.

Hey Don, it looks like you're really getting this heli dialed in nicely. I have started using a little bit of nose biased CG in my scale machines. Nothing pronounced, just a tad of bias. I have seen you fly and your helis are dialed in to perfection. I have never noticed any porpoise effect during your flights. I think that the porpoising effect that we see in most peoples vids is probably more a case of too high of a head gain setting, or lack of finesse on the elevator control. Not to say that improper CG doesn't play a factor too. I'm by far NOT the most talented pilot out there, so I spend a lot of time getting my CG and mechanical set up correctly. It makes me look better when I fly...

Thanks Barry. I am going to be doing some comparisons with my Jet Ranger as it seems to be the most stable in a pedal turn. The 500 and AS350 tend to fall off and that has me looking at the settings and comparing them to the Ranger to see what is different. I have already noticed that the 350 has the highest gain and the 500 has the lowest. I am stumped about that, trust me. I will be looking at cyclic rates and the tail pyro rate. My Ranger is not maxed there but is higher than the other two. It might make for some interesting pedal turns with the 500 or it might be an out of the park hit. I'll be trying to do that this weekend as next week is completely booked. Take care.

When I do a pedal turn I'm still inputting a little cyclic to keep the heli somewhat level to a little nose down. You're correct, every heli has it's own personality, just gotta find the sweet spot.

The Boys are Back in Town

Ok, I went nuts and have decided to enter IRCHA in the Sport Scale category. My helicopter does not exist so rather than get a whole bunch of low marks for a fictitious helicopter that has no documentation possible, I will try Sport so that all I need is a 3-view drawing and a declaration. I have added a bunch of stuff that was removed when I stripped it down for repair and painted the head, blades, and tail housing. I also put about 75 screws back in that were take out for the next body. That will be on hold as I am building a new Jet Ranger to replace the badly scared factory finished body. I might have it finished in time for the Southern Scale Challenge but for sure by HSM. I will have the winter and spring to build the new TOW Defender body. Take care and see a lot of you at IRCHA.

Hi everyone:

It's been a long time since any updates have been done to this thread. All in all, this helicopter had taught me a great deal about setting up my helicopters and has enhanced my flying skills a whole bunch. Naturally, with those teachings come some hard learned lessons like to check and double check battery condition BEFORE closing up the canopy. I did make it to that IRCHA gathering in 2014 and did myself proud by placing second to a young up and coming Vario pilot named Robin Adamschak. It was not pretty back then, as there were many things not right with it but I got over it pretty quickly and just had fun.

This spring, I went to Louisiana and to Eric Babineaux's Cajun Classis, where I met Len Mount and Michael Coveney. There, both Len and Michael gave me pointers on how to better present the models and I am sure that their help made it possible for me to have done as well as I did at the US Nationals this year. At the Cajun's, I won the Under 700 trophy with the TOW Defender, which was there as a backup flyer for my CH-139.

With the US Nationals coming up, it was time to get this helicopter ready for one last kick at the can. I spent the better part of three weeks reworking the CH-139 so it better matched the original helicopter. It was time to start the fixing process of the TOW Defender for its run at Sport Scale. I really got it mixed up last year and thought that IRCHA had the Sport Scale division and found out really fast that it was not the case.

The TOW Defender has been missing the second launcher for the better part of two years so it was time to buckle down and put a brand new one together. The hard part is matching the paint as the spray I use is slightly lighter and it would stand out like a sore thumb. I worked out a spraying technique that blended three layers of paint into one and the match was perfect. Armed with a freshly repaired machine, it was off to the NATS.

I flew it to a perfect win, coming first in static and all three flying rounds. It was not a cakewalk as anyone that has seen the other two contestants fly, can tell you they are well experienced and hold their own against all competitors. I talked to a few people at IRCHA about the fate of this bird and most said that it would be a good time to sell it. I only made a slight attempt to move it but so far, only one person had a nibble at it.

I had one of those senior moments, once again, at Rochester and broke the landing gear. It was not serious as I flew it at Dalton with those same broken gear and with the woodwork repaired. However, the gear had to be fixed if it was to be sold. I dug out some spares that needed to be repaired themselves, and pinned them together and began building the heavy duty skids from those. At the same time, it was a good time to fix the wiring to the lights. And so it happened that I might as well have just fixed the entire helicopter and be done with it.

So now, all the lights are back in operation, the landing gear sits ready for aging, and the TOW sight is back doing its own thing when I flip the appropriate switch on the transmitter. I am getting ready for Florida and should be found in at least five fun-fly gathering throughout the state in the next month. I have a brand new head ready for it when I get home (the sk-rotorkopf head is going to the new build) and I will continue to rework it over the winter. Yes, it is gone from competition but it is not gone from making it out as much as possible. If it is not gone by November, it will remain part of my stable for a very long time. Here are a few pictures from the past year ending with it sitting at the Burlington club with all lights on, ready for a night mission. Take care.

Thanks for the comps. The sad part is that this past October, it was destroyed in a crash that was caused by a faulty satellite receiver wire. I am now in the process of building a new helicopter to replace it. I am not sure if I will have it ready for any competitions next year but it will be flyable shortly. The mechanics survived, loosing only a few parts plus the boom which was folded in half from the impact. It happens. Take care.

Don I didn't know you lost that machine! I am sorry to hear that. seems the nats winners have been hit with crashes after their big win this year huh? My 407 is on its way back to recovery.
what are you building to replace it?

Hi Emile:

Sadly, both were total losses and the CH-139 lost not only the body but the chassis as well. I am replacing the TOW Defender with a Little Bird that is on display at the museum in West Chester. It will be fully crewed inside and out. Yours should be as good as, or even better, than new when it re-appears. I'll see you soon.
