OK, I'm in for one of the new Hanger 9 B-25's. Called my trusty LHS today. My main man there said late August. Horizon has a program called (Fast Forward) where their better retailers get shipped first. He is one of em.

OK, now lets talk gas motors. whos got ideas on what gas engines to put in this bad boy?

So far, it looks like the rumors about the TF b-25 having a fiberglass fuse are all guesses at this point. There is no mention about it on tower's site, although the preview model from alst december may have had a glass fuse....dont remember. Anyhow, Im still opting for the H9 version at this point.

As far as gas motors, well, the G20's would work fine......but will be rather heavy. There is some place(dont remember who online) that will convert a standard saito 4 stroke to use gasoline. I recall they do it most often to a saito .82 and those are well within size limits for a B-25 of this size....although overpowered

for the plane......never rally can tooooo much power unless it shakes the plane apart.

kahlog,

I also thought of the G20's, also thought of the evo 26GT's. Either way, I'm goin gas in this bad boy. If you and Rip decide to go also, I think I can get us a nice discount for 3 of em. Thanks for the input. She might end up a little heavy, but she sure is gonna sound goooooooooood!

3 total b-25's? or 3 sets of gas motors? Please keep in mind, there is a shop up this way in greeley called "Things with Wings" that is usually quite alot cheaper then most name brand hobby shops like Hobbytown....and definitely cheaper then Horizon. Please keep us informed though as price comparisons are always good, especially if it results in savings.

I've got my e-flite 46's on order. I like to keep my airframe nice and clean.

I am going to try eletric on this baby , twins scare me and this is the perfact plane to take the dip with e-flight

I agree. Putting gassers into this will make it heavier than necessary. Two 52 four strokes would power it nicely although I'm a bit warey that one is most likely to cut and make the aircraft difficult to handle.

I've had lots of success with electric conversions, my latest two are Hangar 9 Spitfire and F-22 Raptor.

Can't wait for this baby, anyone for moving turrets or working bomb bay doors?

bomb bay doors would be nice....except the battery hatch is located in that location. For those using fuel power, it might be possible to alter this and make doors. For those using electric....hmmmm. Will have to see once kits are in hand.
As far as one motor going out on say a twin with smaller .52 or so 4strokes, well, if you hit LVC(low voltage cutoff) with electric motors...say the Power 46's, it'll be the same issue. Make sure you have ALOT of rudder available, but, generally, if a motor goes out on a twin, the idea is to shut down the other one(or briong it to idle) to prevent a yaw into spiral meets ground problem and land the plane quickly.
I know people can fly on one engine, but reacting to one engine out fast enough can be problemtatic(if electric). On a fuel motor, usually there is some warning like weird noise...but not always.

I've got a few twins(electric) and i have had a motor quit. This was on an A-10 where the two motors are quite close together. From the point that the one motor dropped, it took about 3 secs for instability to occur and yaw the plane over into a death spiral. If you can recognize whats happening in those 3 secs, you can save the plane. If not, kill the motor as soon as you realize whats going on and land straight ahead from where its pointing. Trying to bank and such to line up with runway with no power or only one engine on a twin and losing airspeed on a heavy plane is not a good situation.
Hopefully, H9 has designed the B-25 to be a decent floater so power isnt critically required to effectively bring it in. My FSK B-25 does require a little power to land up until touchdown, but my P-38 can glide in with motors off.

Chances of electric motor going vs. IC is less IMO. As long as both motors use the same escs (one each) and they draw from the same battery they will gradually run down the same.

With new electric set-ups I generally fly for a few minutes, charge the batteries up to see what I put back in and then extend the flying time gradually. I tend to leave 25% in the battery pack if I can help it and not run them down completely although I've had a few dead sticks on my Spitfire as I flew on more throttle because of a windy day.

H9 haven't put the user manual there yet, I like to have a good look over and see what I need to shop for.

Any idea what servos it will need (being 80" and 16lb)? I put 3152's in my H9 P-47 150.

Wonder if they will suffer from the same wrinkly covering I am getting with my other H9 aircraft?

Generally yes, IC will cut out more frequently then electric provided the LVC is taken out of the equation. However, please keep in mind.....NO TWO esc's will behave exactly the same. So...two Castle Creation 80 amp esc's(or whatever your using) will not read the voltage exactly the same due to internal tolerances at the manufacturer. One esc WILL cut out before the other if flown close to LVC and neither esc will draw the exact same amount of voltage as the other. One side(meaning one motor) will spin at a slightly higher or lower RPM then the other even with same setup. As long as the RPM difference is not above 500 or so, everything is fine. This also happens with two IC motors. No two are the exact same.

So...as you've said....test fly initially for a short duration to see how much juice was used and due subsequant tests after recharging until you find the max flight time while STILL giving a safe margin avoiding LVC. Running out of fuel in IC motors would be the basic same thing as hitting LVC for electrics(except you can usually reset an electric motor for 1/4 to 1/2 throttle) or set a soft cutoff...recommended.

As far as the wrinkly covering.......one way to counter this is to overspray the plane with a flat clear paint. It does work rather well and lessen the wrinkle effect when sitting in the sun for extended periods of time. I had my H9 Corsair out at the field for 5 hours sitting in the sun and it did not develop any new wrinkles and it was a nice 85 degree sunny day. I had sprayed it with Model Masters flat clear laquer.

Looked nice. Flew quite well even using those ugly 10x4 PTS(progressive trainer system) squared off props. Mine will use normal MAS 3-blade props and after hearing the plane on the video using 2 x 2strokes.....thats not happening. Defintely using 4 strokes on it.
