Can You buy the converted engines NIB?

- I bought mine from Bruce Hanson in Las Vegas Nevada.

- http://www.bhhanson.com

- Ralph Cunningham does the ignition conversion.

- http://www.rcignitions.com/

- Check them out. I don't exactly understand their business relationship. Mine was NIB from Hanson.

That would be easier for me, rather than sending the engine to the states.... It is the older version of the H9 cap as the new one is not avialible here yet. I have found the APC props to be quite good in this size range also. The 18x8 on my extra works very well and has alot of vertical for a large heavy plane.

What type of radio setups are you guys running in this size plane? I was just thinking a single 2000maH for receiver and a single switch. I am running dual switches and receiver packs in my extra, do you think it is required in this size plane? I will be using digital servos, so I will need a decent size receiver pack.

- I just run Hitec 605 servoes in the Pitts. Two on the ailerons, and two on the elevator. One on the rudder. My GP CE II is using HS645MG and HS635 servoes. My Extra has HS605MG aileron and elevator. Cirrus coreless with belcrank on rudder. All perform fine. I'm not a 3D or precision pattern flyer-- just a hack. Batteries are 5-cell Nicad packs. 1100mAH in 1/4 scale planes. 1500mAH on GP CE II. Second guessing myself a little on this one. Bigger and more expensive? Definitely go redundant.

I have two caps. A Midwest 80" with a BME44 gasser, the yellow one, and a Kangle 232 with a Moki 1.8. They both fly well and the gasser flys great and does 3d well too. I think the BME44 is a great choice in engines for this size plane.

Bigsport,

I forgot to mention that they seem to build these in batches. When I first inquired, they we working on a batch. Delivery was 2 weeks. I called Bruce a couple weeks later to order and they were in stock as promised. I received it in 2 days.

Bruce has a relationship with Zenoah and somehow the warranty is not affected. I didn't verify this with Horizon Hobbies (Horizon is the importer in the states). The ignition is warrented forever. Service could be a bit of a problem down under.

ten pillows.

Looks like the Aeroworks Ultimate in the photo.

What are you running in that? My friend just got his back in the air after converting from Moki 1.8 to BME 50. Only has a couple of flights on it but looks like it is an awesome setup.

Thanks for that terryj, I had a look at the hanson website! The engines look good, and sound powerful. I will send him an email and find out a little more about warranty etc! I think I will go for a little more power on the sero's than you. I tend to fly more precision aeros with the tumbles and spins thrown in. I love the way digitals servos perform so I'll stick with them. Not sure extactly what I want yet but I'll have a look around. I agree with you on redundant power packs. I'd hate to loose a plane like this to a battery or switch failure. Just wasn't sure what other people are running in the caps. I guess the weight penalty isn't all that much....

Nice planes ten pillows, but where are your wheel pants????

I have not seen this plane berfore... Is it an ARF? What are the specs? (wingspan, length, weight, etc). How does that top flite prop go? I've been told the flex alot and don't produce a great deal of thrust.

No, it was not exactly a ARF. Fiberglass Fuselage, Foamcore wing panels, same on Stabilizer. had to assemble, cover and paint it.
WS : 74"
Lenght: 72"
Weight: 11 lbs

Kit was build in Canada 3 Years ago by GENESIS, same Folks who now have the Waco Kit for Sale.
Can't say who the distribitor is. This Puppy flies pretty good, the TF Prop was marginal, have a Menz 18x6 on it now, much better performance.
I understand, most of the Kit's for the CAP 232 were shipped to Japan and other places in east Asia, I received one of the last ones in production.

How do you calculate wing loading? I would like to try and figure out what the wing loading will be using the G26 on the minicraft cap. I think depending on servos and batteries the AUW will be between 12-13Lbs.

Bigsport:

It's the Weight in ounces divided by the Area in sq feet. The area is the average Chord times the Span divided by 144 sq in/sq ft. So....

W/(Chord x Span/144) = WL

With the answer in this case as ounces per sq foot.

Hope this helps....

I have a plans-built D&L Designs 78" span Cap232. I have a ZDZ 40 on it. It weighs two ounces shy of 13 pounds. It does awesome 3D. The problem I have with it is that the designer put the landing gear in the scale location which pretty much sucks when flying off a grass field with a 22x8 prop! A 20x10 is better, but I still have to fly with a rearward CG or it tips forward if the grass is too tall. That's hard on props! An aft CG on a Cap isn't a very good idea. I have to switch the elevator to low rate after every 3D manuever or I fill my pants, but that is true for most large aerobats. I talked to Doug Lee (he had a table at the Tucson Shootout) about the CG problem and he recommended that I move the gear forward. I had already decided to try that but haven't gotten to it yet.

So a gas powered 78" Cap under 13 pounds is easily done, and I'm glad. I just can't see "flushing the toilet" with 24 ounces of glow fuel for every flight!

I'm done with the plans so the first $20 gets them shipped priority mail. (Sorry, just sold the plans!) Doug has laser cut wood kits, gear, canopy, and glass parts available. http://www.dldesigns.net/

PM for pics and info. I might even sell the CAP to fund other projects. (These stinking foamies are addicting!)

cool tanks for that. It works out that if I keep the weight between 12lbs and 12.5lbs. I will get a wing loading of 26.8oz/sqin and 27.9oz/sqin. Even at 13lbs the wing loading is 29.0oz/sqin. So if i keep the weight below 13lbs max, I should have a nice flying plane!!!

I agree with you CHM on the fuel issue. Its just so much cheaper and cleaner to run gas..... I doubt I will ever go back to glow!!!

I have the prototype wooden version of Genesis Caps and it flies GREAT. The Genesis version was modified from the version I have. It has bigger control surfaces, and some other minor changes. I think the fuselage was also stretched. The big downside of Genesis caps is the fibreglass fuselage combined with a cap. I produces HEAVY tails and light noses. These aircraft were badly tail heavy and required to take that into account in every step of construction. Yours at 11 lbs is the lightest I have ever heard and if you are not too tail heavy, you must have a good flying plane but that is far from the norm.

3D joy, Is it just me or is your undercarriage very tall? Just doesn't look right. What engine are you running?

Does anyone know if the H9/minicraft cap has servo trays in the tail? Or are the fitted up front? I think I will go for the G26 and slimline muffler for power. Not sure if I should get a converted one or try the mag setup first!

Yes it is a bit tall. Depends on the angle you see the aircraft as in fact it is not THAT bad. Another factor may be that it is at the same time a bit narrow...

The engine is a YS140DZ. On the photo, it has an APC 18x8 when I flew with 20% nitro but I then switched to 30% nitro so I had to change the prop to an APC 18x8W. It spun the wide blade at about 8400 RPMs.

You should defenitely get the converted one, I am really not sure it will provide enough power in the stock configuration. In fact, I am not sure for the converted one... That is the answer from a YS guy.

The absolute minimum in size for a gasser of very good performance is about the size of the plane of CHM in post #36. That aircraft must be really interesting.

I pretty confident that I can do this with the G26. From what I have read the converted engines don't make much more power than the mag engines, however the biggest gain is in the weight saving. Caps are know for being tail heavy so wouldn't the extra weight be an advandage, as long as it is not to much! With the wing loading calculator I figuured out that if the AUW is kept between 12-13lbs the wing loading will be in the 26-28Oz per sq ft range. Isn't this around the normal range? I realise lighter is always better, but I think it is possible to do this and still have a great flying plane. I may not be an all out 3der, but I don't fly really fly 3d.

Ram1500, By having a look at the G2300 specs I think that engine would be a good choice. I have not had any experience with super tigre engines, so I can't comment about reliability and tuning however if it will turn an 18x6w or 18x8 at 7500-8000 you should be fine.

Do you fly 3d or just sport aerobatics? Also does your plane have cut outs in the tail for elevator servos? I think If I run a G26 I will need the servos in the tail for balance! Can You post some pics of your plane. Still no pics of the H9/minicraft cap on this thread!! I can't wait to get mine.

I have checked out the converted G26 engines and they are going for $425 US. I think I will probably go for a converted engine, but I need to get my trailer first. My car is to small for the big planes and I've been using a mates trailer to get them to the feild. I don't want to push the friendship to much. So once I have a trailer I will be full steam ahead on this project. I can't wait.

I have a world models 73" cap 232 with an OS 1.60 mounted upfront. The verticals are practically unlimited at 11.5 lbs with a wing loading of about 27.65 oz/sqft. All caps are generally snappy and so is this one, especially when u pull a wall. But, this thing is a beauty to harrier. It locks into them with negligible wing rock.

I'd like to bring sown its weight to around 10.5lbs, but dont know how to. suggestions?
