Hey Mark,
I enjoy it every time I fly the plane. I was just out flying it last weekend and put another 6 flights on it which has put it well over the 100 flights mark.

Thank you
Nickelup,
I used JR8911HV's thru-out the whole plane even the throttle and choke.

8911 on a choke? Bit of overkill IMO... but if you want to spend the money, why not. I use these thin little spektrum servos up against the firewall with about a 1" linkage. Think they're around 60oz of torque.

I know what you mean Greg. Look in the drawer of servos... pray you have a cheapie for stuff like that. I have a plane with an 8611 on the throttle because it was all I had loose...

Over kill on the throttle servo usually insures no dead stick landings!
Same with gear and elevator and it better be 'double batteried'.
Why ask: I'll think I'll save 10 bucks on my several thousand dollar plane!

Thank you I ended up using spektrum A6150 HV. I think they are good enough for what they are intended for

Nickelup,

That was another good option for the throttle and choke. I used those thru out my Wildcat that i built.

I have a 2 blade 32 x 22 prop that just been laying around, would that be ok to use on the moki 250 with this jug? They are recommending 3x19 for warbirds. What you guys think? Thank

NICKLEUP,

That should work just fine. It will load up the motor enough to keep it in a good safe RPM range.

Guys do you recommend using epoxy/milled glass for mounting the radio tray/items inside the fuse or should I go with hysol?

Hysol is the easiest, strongest and best way.

Ready to fly (I think)
Well, It has been a long road but the CARF Jug is about ready to fly. Doing some final testing and calcs. Wondering if any of you guys have found or done the math to get the wing area on that bird? Mine sure seems to be heavier than anticipated but balanced perfectly with no additional weight needed. I did use small servos for the gear doors, a Figoli actuator on the canopy and an electric fuel pump but other than those items I don;t know how I could have gone much lighter....maybe no paint Just wondering how many of these really come out under the 24kg (53lbs) that CARF specifies. Mine did NOT! by a fair margin.

Hope this big fat pig flys

Nice Tom, really nice.
I have one on the board too, so I can fully appreciate and understand how much work there is to do on this model. As you will surely attest, it's a TON of work to complete to this point, as you have done. Maiden date ??
Cheers-Mike O

Nice model!
Don't worry about the weight. My CARF Corsair flew at 65 lb+ with no issues and I think it has less wing area, not to mention it doesn't have the semi-elliptical wing the Jug has. It is amazing what that Jug wing will let you get away with.
Congrats on completing an outstanding warbird.

Mine weighs right at 55 lbs dry on the Xicoy scale. By the way, mine is the one Richard wrote this thread about, it's sweet!

We took her out to the lakebed last Friday to fly her maiden flight. At 62lbs I was kinda nervous. By far the most weight I have ever pulled off a runway without being in the aircraft. She flew wonderfully. No bad habits that I saw on the maiden. Full flap extension did not pitch the nose up or down it just slowed down a little bit. Been having some issues with the gear but they also worked well.

Thanks to all of you on this forum who have provided assistance during this project!

Here are a couple of videos of the maiden:

Next in the project queue is the Gaines Smith 120" A1H SkyRaider

Life is GOOD!

Tom,
Great looking and flying P-47!
Well done on the maiden flight.
Kinda hard to overshoot that runway!

Hi Greg,

Thanks for all your help with my CARF P47. I have one last bug to remove from the plane. I am having trouble keeping the three cowling bolts in. I really don't have that much vibration with the Moki. I don't want the cowling to come loose with the baffle on which could destroy the pushrods. I even bought the Nord lock washers, but still lost one bolt. I am thinking of even rethreading the tabs that hold the cowling on. Did you have any trouble with this? Thanks again for your help.

Hi Mark,
I had it happen to me twice and I'm aware of two others that had it happen. In my case I solved it by gluing a 10mm hardwood block behind each of the cowl brackets. I then fixed 10mm long M4 stainless steel inserts into each block. This combined with a little thread locker has given me no further trouble. When my cowl came loose, I didn't have any problems with pushrods but as the cowl came forward it impacted the back of the prop - it's a scary noise when that happens. Fortunately in both cases the damage was slight but certainly something to be avoided!
Hope this helps
Bob
