This is the same problem I have experienced a couple of times. I thought of using threadlock or perhaps replacing the existing nuts with lock nuts.

Here's how I did my throttle and choke.

I flew the P47 again today and got the engine dialed in pretty well now. I picked up 300 RPM just cleaning some plugs and replacing three others. She's turning about 5400 now and running plenty strong. The difference is noticeable. The plane climbs out with more authority and pulls a much better (larger) loop. All at 44.4lbs the 150 is really the best, most realistic engine you can get for the Meister 47.

I pulled into Warbirds over Atlanta this morning and it is one beautiful place to fly. Flying the 47 there for the first time today was a gas. I was so happy[sm=49_49.gif][sm=biggrin.gif][sm=lol.gif][sm=teeth_smile.gif] to get the engine right and now I'm ready to go on with the show. Met up with Frank Tiano and his 47 which took some damage during his trip up leaving him a little bummed to say the least. Hopefully we'll get it fixed and airborne tomorrow. Also met with Jeff Naul today as he was setting up his 47 as well. Tomorrow we'll get them together and take a few pics for you Moki fans.

If some of you readers are coming to the event please stop by and say hello. Always love to meet and talk for a bit whenever possible. See you there!

Scott,

Sounds like your having a great time!! I'm glad to hear how well the 150 is running too..... :D Anymore Moki's at the event?? I would love to see a few more pics of some of the nice warbirds at the event...

the moki powered P47's, etc were sounding beautiful as usual at Warbirds over Atlanta. Just be careful during dead stick landings:eek:[:@]. including turning away from the crowd.

RE: MOKI RADIAL Care and Maintenence
 

David,

In the name of safety that is always the correct thing to do....no doubt! Not always an easy thing to do when you are completely concentrated on trying to safely bring your bird home. Thank God no one was seriously hurt. As soon as the pilots eye met with the crowd it seemed obvious to me that he dumped the plane in the grass so as to avoid an air born collision that could of resulted in serious injury.

So as not to detract from the subject of this thread (MOKI'S) I want to say you're right! The sound of the Moki's were awesome. Flying the halftime show with Frank, PJ flying Jeff's 47 and me with mine was a ball. If my plane wouldn't of met with a total calamity of problems (no engine issues) I would of loved to do that all weekend.

Guys, all three Mokis ran real well other than one dead stick that happened to Frank after flying a lengthy slow flight pattern. Not quite sure yet what caused that but we'll dig in and find out, I hope??? I will post tomorrow some more pics and try to give you the short version of my weekend of bad "mojo" between me and the 47. I've never had so many things go wrong one flight after another and not total the plane. I brought it home but with a real sore wing that will have to be totally rebuilt. In fact I got the complete wood kit from Dino while I was there. I'm going to bed...........more tomorrow.

Oh ya! Big congrats to Jeff Naul for getting his engine fixed and running better than ever. His plane and now the engine too are fantastic. Jeff it was cool to meet you and good luck with the 47. Keep us posted on your flights, experiences and color scheme. Bring 'er down for Monster Planes!

Regards,
Scott

Guys,

In keeping with the subject matter of MOKI's I've posted the story and pictures from this weekends trip to Atlanta Warbirds elsewhere in the following thread.

That should get you there. Have fun and see ya around,

RE: MOKI RADIAL Care and Maintenence
 

Once again congrats to Jeff Naul for getting his Moki 150 performing well. As he suspected the pick up sensor that is bolted to the nose of the engine became loose. Once tightened and glued back in position the engine ran well. Jeff said it was better than he could recall. He flew the heck out of that thing and all he needs now is a paint job.

At least we learned something about that pick up. One more thing to check and make sure it does not come loose. Mine has never moved, thank God.

Anybody out there running any different prop on the 150 besides the 26 x 16? Just wondering. We all ran that prop with great success and I don't have a reason to change but was interested in what others were doing???

Scott

RE: MOKI RADIAL Care and Maintenence
 

Attention 150 owners!!! Here's a few pictures Dino D. at Meister Scale sent me confirming another 150 Moki airplane. This one is the FW190A that is produced and sold only at Meister Scale. Looks like another perfect fit for the radial we love to hear. Can't wait to get some updates from Dino as the project moves along. If you're interested you can find the kit at www.meister-scale.com For those of you that haven't met Dino, your in for a treat. Not many guys out there that will work harder for you than him. Being a customer of Meister Scale and Dino is one great experience.

Soak in the pictures and give Dino a call. Looks like a cool project.

If you guys know of other MOKI projects please send them in. We need to know what kits/planes work well with which MOKI?

Thanks for the Pics Dino,

Scott

RE: MOKI RADIAL Care and Maintenence
 

Scott,

I can't agree with you more about Dino and meister-scale!!! Great guy and excellent products & customer service!!!

RE: MOKI RADIAL Care and Maintenence
 

Hello Guys,
I've been working throught the install of a MOKI 150 in my Wild Hare SU-26. I have been flying the SU-26 with a DA-100 for 6 months and decided to switch to the radial after seeing the fellow on You Tube (Norway, Sweden?) fly his. The engine is a good fit, although I have not decided on a practical way to get the CG right. I think the MOKI is 4 lbs heavier than the DA. I built a tray as far back in the fuselage as possible and relocated the receiver pack batteries, but additional weight is going to be needed to get things right. I plan to run the engine this weekend if the rain will stay away.
I'll add some more photos with the cowl off in the next post.

RE: MOKI RADIAL Care and Maintenence
 

Hello again,
The 150 engine cranked right up and ran smoothly. I checked the rpm with a 28-12 prop installed and the RPM topped at 5350. From what I recall from earlier posts, that's a little high. Does anyone have a suggestion on proper prop size for the SU-26/150, maybe a 30-10 or 30-12? As usual, I appreciate the help.

Jim

RE: MOKI RADIAL Care and Maintenence
 

jim, thats not too high. i think that is a little under propped. i went to a 28/14 and could turn it 5300.

Very nice looking Waco :)

RE: MOKI RADIAL Care and Maintenence
 

Thanks Jeff. I won't worry so much about it. What 28 x 14 prop are you using? I would like to try a three bladed prop on my 150. Got any ideas what size might work?

Jim

RE: MOKI RADIAL Care and Maintenence
 

Jim, the 28/14 is a xoar. it by far outperformed the 26/16 Bambula. i found out after changing to the Xoar that the Bambula's are not as good performers. I would imagine that it would turn a 26/14 three blade.

RE: MOKI RADIAL Care and Maintenence
 

Jeff,
I'll try the Xoar 28-14. I like Xoar props too.

Let me ask you and the group another technical question. The radial has added 4 lbs to the nose, over what the DA-100 weighed. I've been struggling with getting the plane balanced close to the original CG. I am not one to add a bunch of lead to the tail if I can find another way. I started by moving anything that had a resonable amount of weight toward the tail. Offsetting 4 lbs takes a lot of relocation to even get close to a proper CG. I switched reveiver pack batteries to 7.2v NiMh, 4200mh electric car batteries, built a tray as far back in the fuselage as I could manage, and ran heavy duty wires to a Smart Fly Super regulator, output adjusted to 6 v. The only other heavy item is the engine ignition battery which I have not placed as yet. I have called a number of people in the business and asked about the interference issue as it relates to 2.4mhz. Several have told me that there is no issue with 2.4mhz and to place the battery anywhere in the plane. Others, I suspect former 72 mhz guys, still advise against locating the battery near, or running ignition battery wires past the electronics (receiver). Of course, I would like to add one more tray in the tail and put the ignition battery back there, running shielded wire through the bottom of the plane to the ignition system.
I know that this is not a direct MOKI question, but I'm sure others will be dealing with similar CG issues because of the weight of radial engine. Do we still have an interference issue with 2.4mhz?

Jim

RE: MOKI RADIAL Care and Maintenence
 

Jim,

I know this is not the answer you were looking for but maybe worth a try. Try leaving the ignition battery in its current location and put the plane on the balancer. Take little one ounce pieces of lead and rest them on the tail until you balance. You might find that back there you only need a few more ounces to get it to balance (considering the moment) and your problem is solved. No hassle in relocating the battery and only a couple ounces added in the tail...big deal???

For the record. I have put the ignition battery behind the receiver in a Moki engine airplane and ran HD leads to the ignition module with no problems. As I understand it, interference is not an issue with 2.4 I have been very happy and confident with that installation.

Nice looking workshop and plane stand you have there. Good luck with your project and keep us posted.

Scott

RE: MOKI RADIAL Care and Maintenence
 

I agree with Scott. Your plane probably has a 4 to 1 ration nose to tail so you will need about 1lb in the tail which is not that much.

You have already added a pound or more in your choice of batteries and did not gain that much due to fact you could not get them far enough rearward. Switch back to li-po's or li-ion's then grit your teeth and add the weight. You can make it look nice latter......... just my 2c worth.......
Paul

ps I have a 250 in a comp-arf corsair, that is why I am enjoying this thread.......

RE: MOKI RADIAL Care and Maintenence
 

I know you guys are right about the lead. A pound is not that much. In the end, I'm adding some lead as far back as I can get it to get the CG right. My thinking here is that it's better to use bigger batteries that do something than to add an even greater amount of lead that does nothing :-)

Scott...... The stand is new and really does a good job of holding different large planes at strange angles. It's also very low profile when folded and does not take up much space in the van.
I'm nearly out of room in the shop. As you can tell by looking at this photo, rc aircraft can become an addiction. My buddies keep telling me that I need to join RCA. It's another version of AA. "Hi.... I'm Jim and I'm a modelholic"

RE: MOKI RADIAL Care and Maintenence
 

I got room for the F16 in my garage:D:);)

RE: MOKI RADIAL Care and Maintenence
 

The answer is no, on some of my models the ignition module and receiver/ignition batteries are only inches apart. Forget what ever you had to take in consideration with the 72mhz.
Pack your batteries all the way in the back and be a happy camper.
The 2.4 does not know interference. Not from any gas engine with electronic ignition - even an unshielded spark plug cap does not effect the 2.4Ghz.

RE: MOKI RADIAL Care and Maintenence
 

Hello
Excuse me if the subject has been already written but I have a MOKI250 on a P47and I search a 4 blade propeller. I know there is the Biella in 28*18 but I want to put on the moki a Solo prop 4 blade. So could you advice me on the choice of the best solo prop for my moki.
Thanks a lot in advance for the advice.
Regards.
Philippe

RE: MOKI RADIAL Care and Maintenence
 

pete, i helped a friend with a crrc26, with 2.4. the ignition battery had to be moved to the firewall because it was getting hit. i thought the same thing when we set up the plane, it's 2.4 and won't get hit. not true in our case. the battery's were next to each other originally. jeff
