RE: Hangar 9 B-25 ARF: Building and Modifications
xman,
Looks great.
Hey another thing to think through in your construction process is the CG. with the Saitos mounted as is, I had to put the batteries (2x5cell NiMH AA packs) in the fuselage just above the wing, not in the nose as stated in the manual. If you use the stock engines, it may be even farther back.
Just wanted to give you a heads up!

RE: Hangar 9 B-25 ARF: Building and Modifications
Hmm... That would suck... I've already mounted my batteries in the nose (one 5200mAh Li-Ion - radio, and one 2600mAh Li-Ion - glow driver), and ran all wiring to the switches....plus I am mounting my receiver and voltage regulator above the wing.... and I am using a pair of 62 Saitos. Oh well, I'll see what needs to be done when its all together....

xman,
FYI, I have 3 pilot busts, adding to the nose weight. I also added the gun kit from dbalsa. This probably added a little nose weight as well.
I had my batteries up in the nose as well, with the wiring all done (i use two receiver batteries with two switches for redundancy sake. 2400 mAh NiMH AA 5 cell packs) Had to totally redo it.
Now, I am also using retracts, which I believe add nose weight as well. I was told to balance with the gear retracted, and it works well that way. Flies great.
let me know how it works out.

RE: Hangar 9 B-25 ARF: Building and Modifications
Ken,
I think that I may not have that problem - you are using 5 cell batteries where mine are a four and a two cell, plus NiMH cells may (not sure) weigh more than Li-Ion... So considering you have 10 cells which is 4 more than I am using (that's like having another battery pack on board), might be the reason why you couldn't have your batteries in the front... And if I still have a problem balancing it... ( the space above the wing is already taken up by the 14 channel FASST receiver and voltage regulator) I'll be adding led to the tail...
At any case should not need much
Paul.

Saito .62 with TurboHeader Muffler Installation
Before I go too far, the 1st, 3rd, & 4th pics were taken with the engine nacelles upside down. Pics were then rotated 180 deg to hopefully make it more clear/ easier to understand.
As you can see, both engines are mounted at the same angle: an angle which lines the 'jugs' up with the nacelle exhaust cutouts. I did this to assist engine cooling.
Then, with these neat little mufflers: I was able to point the exhaust down and outward from the aircraft on BOTH engines (I am also using the 90 deg adapters). The possibility exists that with these mufflers, 90 deg adapters, and some exhaust tubing: a somewhat scale exhaust could be fabricated (for the B-25B).
Pics 3 & 4 are sideviews of right and left nacelles respectively, each taken from the outboard side of each nacelle. In other words: this is how they look from the side that is immediately visible, NOT the side that is facing the fuselage.
After reomoveg the cowls, I rotated 1 muffler so that it could actually use the existing exhaust cutout on the naccelle, just to show the possibilities with these mufflers. Mounted as such, it could be completely inside the cowl. But, since the Saito .62 sticks it's big head out of each cowl anyway, I opted for a setup which will divert as much exhaust AWAY from the aircraft as possible.
Last 4 pics illustrate throttle linkage hookup (left engine shown, but same on both engines). A Hitec HS-81 is used, I hade to use some old Hobby Lobby mini servo mounts to make it so I can remove the servos if/ when necessary. I needed to make the wire into a 'hook' ("U" bend) on the engine side due to lack of room for more conventional hookup.

RE: Hangar 9 B-25 ARF: Building and Modifications
Hey Jock,
Looks good... I like those mufflers, very neat install....but I am going to use the stock mufflers - cannot see spending $160.00 or more for a set of those (I am guessing the adapters had to be at least $15.00 a piece on top of the mufflers...), at least for now - money is scarce those days....
Are those stock engine mounts or did you get different ones?
Paul.

RE: Hangar 9 B-25 ARF: Building and Modifications
I've used Hayes AL-40 mounts on every Saito .50/ .56/ .62 that I have ever mounted (quite a few over the years):
http://www3.towerhobbies.com/cgi-bin...&I=LXK809&P=SM
Sometimes I have to modify them a little/ remove ( with Dremel ) some material to make the carb fit properly, but otherwise they are solid, light, and compact. They DO require drilling and tapping for engine bolts, and I use Lock-Tite when I mount the engines.
Also, as stated in a previous post: those mufflers are on sale this month ( February 2009 ) for 15% off regular price, meaning a pair can be had for $120 + shipping ( $3 ). As for the 90 deg adapters: I used genuine Saito ones, which were actually slightly less costly than the ones sold by the makers of the TurboHeader Mufflers.
Try a Google search for Saito Right Angle Adapter SAI100TI140 and you will find them for slightly over $10 each.
Getting back to the TurboHeaders: I already have well over $1000 invested in this plane ( hope wife doesn't read this ), and that's not even counting ANY radio gear ( Airplane: $400, engines: $400+, retracts: $300+ ). Times are tough ( don't get me started on this: I am employed in the automobile industry ), but since I already have so much invested, AND I want this airplane to look right, AND they are on sale this month: I bought the mufflers and am glad I did.

RE: Hangar 9 B-25 ARF: Building and Modifications
I know exactly what you mean - I work in the industrial side of the industry, and it is SLOW - just had my hours cut to 32 per week.....
Any way, getting back to B-25.... I hear you about having good chunk of cash invested in the plane, but that happens with all of the projects in this hobby... I just finished building a 33% Edge 540 and before I knew it I had over $4000.00 in it....
I was looking a the pictures you posted - I might be wrong, but it looks like if you'd mounted the engines on the right angle, you could use those mufflers without the adapters and they would line up with the molded exhaust relief in the nacelles.... Is there any way you could check it out? - perhaps just by taking some measurements? - if this was the case I just might bite the bullet and get a couple for my plane....

RE: Hangar 9 B-25 ARF: Building and Modifications
I'm not about to dis-assemble eveything to check it out, but I will offer my opinion:
Without the right angle adapters, the muffler would be 'out too far' to allow installing it within the cowl (BIG cut-out would be needed), becuase the exhaust port on the Saito is too close to the cowl line.
WITH a right angle adapter, a the engine cut-out would need to be opened up slightly on the exhaust side to accomodate the adapter (look at my pics again). BUT, the muffler then could be entirely enclosed within the cowl, and exit at the nacelle opening as you suggested (MIGHT need to add a silicone extension tho) IF the motor was installed at an angle different than my set-up.
The Saito .62 (and .56) are really a little too big to fit the H-9 B-25 cowls comfortably. Unfortunately, there are no good alternatives IF you want to install 4 stroke engines in this aircraft, since Saito has discontinued it's smaller engines (I'm thinking the .40 would have worked nicely). I have a Saito .40, and can tell you that it could turn a 3 blade Master Airscrew 10 x 7 with ease, and I'm thinking that if a pair of EVO .36s can fly this bird: a pair of Saito .40s should be able to also.

RE: Hangar 9 B-25 ARF: Building and Modifications
Thanks,
I don't really care if I have to cut out the cowls.... I am more concerned if the muffler will clear the side of the nacelle without using the adapter.... What do you think?

Hello,
I just finished building my b-25 by hanger 9. I wanted to share the video of it taken at our local flying field. If anybody has question feel free to ask!

RE: Hangar 9 B-25 ARF: Building and Modifications
HOLY SH*T! I have flown many of my planes out of really tight landing sites (small/ un-improved runways with obstacles), but you just took the crown away from me. Taking off AND LANDING a plane that big, on a narrow dirt road, with mud puddles on both sides: quite an accomplishment.
What were you doing rzimm001, trying to simulate what it must have been like taking off from Guadalcanal, of some other jungle runway?
Congrats on what I consider a spectacular takeoff, and even more spectacular landing.
1) Looks like you had plenty of power for lift off, so the 1st thing all of would want to know is: what engines do you have on it?
2) Right along with it: what props?
3) The one I always want to know: what is the ready-to-fly-weight (minus fuel)?

RE: Hangar 9 B-25 ARF: Building and Modifications
Hi There!
I have an electric H9 B25 with stock set up (Eflight 46's and 60A Eflight Esc's). It is powered by 3 x 4S 3700mAh Lipo's (A total of 11100mAh at 14.8v). Flies great but I have recently been VERY fristrated with the life of Lipos, noty only only this plane but also on the other larger electrics that I have. This has been even more so on this plane as I bought an unknown brand set of batteries and they went dud on me in afetr a few months. The other good batteries (Hyperion) lasted about two years but still very expensive when you divide the cost of the Lipos by the number of flights!
I have therfore decided to switch all my planes to A123 batteries. You pay a bit of a weight penalty but apparently thay are a LOT more robust, good for (a claimed) 1000 cycles and have a charge speed of 4C (that's 15 minutes!) This means that you really only need one set of batteries per plane!
The A123 proposed battery configuration would be 4 x 5S at 2300mAh each giving a total of 9200mAh at 16.5volts. Weight comparison of the lipos would be (sorry guys, I only understand the metric system!!):
Lipos: 3 x 370g = 1 110g
A123: 20 x 70g per cell (4 x 5 cell battery packs in Parrallel) = 1 400g (excluding connectors etc)
Difference is thus +/- 290g which I don't think is a big issue on this plane.
Also remember that as it will be running at a higher voltage RPM will increase, giving more power.
So.....anyone have a strong views on A123? Has this been done by any of you before on this plane??? Anything??? :-)
Cheers
Keith

Jim,
I did get the turbo mufflers, but decided to try to fit them without the adapters... Here is what it looks like - not as neat as yours, but still way better than stock mufflers would look like. At this time I have only one nacelle done... I just have to clean the edges of the cut out.

I was looking at you engine cutout and noticed that you cannot access you glow plug with a glow driver, UNLESS you are planning on installing a remote glow driver?
Do you ever attend/ participate in the Sundowners Annual Warbird Day (Wheeler, IN, just south east of Gary)? I plan on being there this year (again), maybe we could get a pair of Saito powered B-25s in the air at the same time?

RE: Hangar 9 B-25 ARF: Building and Modifications
Jim,
Yes, I am using on board glow driver - its modified twin cylinder Sullivan products one.... I also used the Hangar9 remote glow driver adapter-the glow plug connector is a lot smaller than the one Sullivan driver comes with, and I like the "banana" style plugs which make for a quick secure connection. (take a look at the picture)
As far as the event you mentioned - I have never been there, but it is something I would like to do, providing I'll have the plane finished, and in good flying order. Can you email me some more information about it?
Paul.

Here is a link to the Sundowners R/C Club web-site:
http://www.midwestsundowners.com/
The site has a VERY Nice interactive Google sattelite map, and states this year's event is on Sat, July 18 (that should give us BOTH enough time to complete ours). These events usually have a VERY large turnout, the field is an excellent flying site, no cost to anyone (even the 'homemade' lunch buffet is offered for donation of your choice), and is generally speaking: the best warbird event within about 150 miles from me. No competition, just lots of warbirds buzzing the runway. We could ask them to set aside a time for only B-25s to fly, and they would probably close the field to the others for a short time.

Sounds good.... I'll check it out. If my plane is ready and still flyable (as in it survived the maiden) I would not mind taking a short trip to drive out there for a day...

Skysdad,
Could you give a little more info on the .36 setup?
What props have you tried?
I have one with the .36's and would like to take advantage of others experiences.
I thought the guys from Horizon were talking about running 9 X 6 props.
Thanks
Bill
