About the decals.
There is a memo included in the decal bag indicating to excahnge the decals. Has anyone been able to determine why we are supposed to substitute one set for the other? |
RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
Remember, I said that there were 2 addendum sheets in the kit.
I did not say I actually READ THEM! |
RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
The situation with the decals is the first sheet (the one separate from the addendum) is missing a few decals (bombs, the white text that goes under the canopy on the left side of the fuselage, and a few other monor things). The decal sheet included with the addendum that says "use this decal sheet, not the other one" is improved. Also, when you get to the end of this project--the very, very end, and you are working on the instrument panel, you will notice the top I.P. (instrument panel) decal that is supposed to have clear windows over the gauges, is in fact filled in with white. What I did with mine was punch out the white "windows" with brass tubes sharpened on the end. If this doesn't suit you, we will shortly be getting in replacement I.P. decal sheets that you will be able to get through Product Support. We should have those in a few weeks.

ORIGINAL: pettit I ran a heat gun over the 4 wing panels and found only one bubble that popped up. Time will thell, though. I can see why this kit is worth every bit of the $650.00 it costs. Carry on! :D Tim |
RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
I use the heat gun not to shrink the covering but rather to "locate" where the unsecured covering may be hiding.
This is pretty much what the sun would do to a plane outdoors. I then use the covering iron with a sock on it to actually secure the covering down onto the wood. A bad covering job looks like "Grandma's Stockings". Not so with the TF B-25. |

Hi, Tim!
Thanks for starting this thread! It's a very neat idea, specially because you're the guy totally involved on the project. Anyway, I'm planning to buy this ARF, but I'm kinda scary with 2 engine airplanes. What I plan to do in order to reduce my chances of a dead engine is to use 2 electric engines AND a sound simulator, because would be a waste to don't have any sound on this beautiful and historic bird. I have no idea on which electric motor to use nor batteries, BECs, etc. I'm a gasser and a glower and never had an electric plane before. What do you think about this project? Thank you very much in advance for any help. Flavio |
RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
Hi Flavio.
Please stand by. Brief instructions with motor/battery recommendations have been written (by Greg Hahn) for this model. Please stand by for a few more days, then check the Top Flite web site. The instructions and a few photos will be posted soon (with the specific motor and battery recommendations). Thanks! (And you're right about me being totally involved with this project--I've now built four B-25s to completion--not to mention all the development/tinkering/testing done with other individual parts/systems/assemblies with this bird!)

I'll pre-order the kit from Tower (they'll have it on late Oct) and Robart retracts. Since I'm in Rio, it will take a while to reach me here, beeing plenty of "standing by"... :) Thanks again, Tim.

ok here are electric specs 2 axi 4130-16 2 jeti77amp esc 2 14.6v 5000mah packs hooked in series thru a y harness. bec must be disabled and seperate rx batt. this setup will be perfect. Where do the batts go you ask well in the scale bomb bay i will be cutting into the aircraft that will open and close via a servo. batts on the cg so they dont affect balance 8s 5000mah will give you 10-13 minutes scale flight according to electrcalc.

with two tims this is going to get confusing fast! Im the Tim who loves electric birds so ill post pics on that part of the build. greg also went e power i dont know what he used.

Hi Stormin Norman
I was watching the other week , when you were testing with youre Deul Ace and you gyro , on the rudder . I watched a few large , twin engine war birds . A couple of them went very well , others not so well . Two I have seen crash on there maiden ( very sad ) , one on takeoff and the other 200 ft high with an engine out . When the engine went out it was very noticable . his left engine quit , and the pilot was fighting the air craft , he ended up doing a cartwheel down the runway . from what I understand about the pilot , he was experienced , but the plane didn t show it While watching youre deul ace with the left engine out , and the gyro , it was not very noticable . I just may try this trick myself , put the gyro on the rudder . I m hopeing to see you at the field with youre B-25 within the forth comeing weeks . it will be extremly interresting . Looks like there will be some good shows at the field within the next few weeks . Michel ;)[8D] |

Hi All,
Looks like some great information here about the B-25. I got mine from the shop two days ago and have been working on the various arrangements for the set-up. Timothy-Thanks for the ideas and electric set-up information you provided. I will also be making mine electric, but I am not certain if I'll use the Axi systems or a pair of E-Flite 60 motors (6s pack for each motor and CC 80amp speed controls). I will also be using an independent power source for the receiver and servos. I like to keep my flight control system power supply separate from my motor power to isolate any possible failure and not loose control of the aircraft. I am very interested in your idea of the bomb bay and actuation for it. Would enjoy seeing some photos of your modifications when you decide how to set up everything. I have been scratching my head here a bit to decide the placement of the lipo packs. I want to keep them near the cg, with the ability to shift them to have correct final cg of the plane. Shouldn't be hard to set them up with ply plates and velcro with velcro securing straps to hold everything in place. Looks like I'll be waiting just a bitfor my retracts though, but it shouldn't be long. I'll take some photos when I get things started here. Final note is to thank Tim and Top Flite for making such a great ARF. The quality of the kit is really fantastic, and I know it will be a real joy to fly once I get mine completed. Tim-thanks for starting the thread and also for the information you were able to share with me ! |
RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
i used the same eflite setup on the 310 . the axis require two 4s 5000ma packs more power and lighter

RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
Timothy, I'll look into the Axi systems, sounds like you have done some very good research on this one. Thanks for the suggestions and information.
|
RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
see you use only 2 packs 4s 5000mah making 8s 5000mah and the axi 4130 is a 60-90 glow equivalent. in my 310 there is no room for batts in the nose so they go in the nacelles creating a heavy plane. it flys well but if i could stuff two lipo packs in the nose i would loose 2.5 pounds cause i would run off 6s 5000 in series. the axi is more poweful . if you want to spend some money get some geared hacker inrunners they run 600 a piece for the motor only!!!!!!!!!!!!!!!!!

Hi, E-Tim! (how's that for making less confusing Tims),:eek:

RE: Top Flite B-25 ARF (Tecnical, tips, suggestions)
axi 4130/16 those are the motors from hobby lobby
jeti opo 77esc speed controller from hobby lobby need 2 of each about 650 worth there batts from prodigy batteries 14.6v 5000mah 2 needed 88 a piece disable the bec on the esc by using a y harness to connect the two. Cut a section ( 1 inch) out of the middle wire on each end that plugs into esc. now plug the y harness into throttle channel on rx and power rx with a good quality nimh jr 6volt 3000mah |
