Tks Tim for the prop-hubs. May be, i can re-machining the original set, i have to compare the diameter.

Concerning the CG, have you seen any differences concerning the flying characteristics when the Landing gear is Up and Down?



Hi Pascal.

Don't notice much difference in this bird with the gear retracted or extended. She's got a pretty wide C.G. range. We do instruct in the manual to check/set the C.G. with the gear down as this is the way we came up with our figures and tested our model. Also, some of you may not install retracts so again, that's why we specify checking the C.G. with the gear down.

Hi KenVC.

Sorry you didn't get a B-25 from the first shipment. The deal is that right now we have the second shipment waiting in our warehouse. I believe the quantity is about the same as the first shipment, so when those kits are released that should fill any remaining back orders. The hold up, (again) is with the decals. New decals should be in this week and as soon as those arrive and get inserted (probably all within the same day!), the kits will be released. So, I think your B-25 should get to you in a week or two at most.

I'll try to remember to check in again and let everybody know when those are released.

Good night everybody. I'll check in again tomorrow (between flying (hopefully), mowing the lawn (maybe), football (watching on TV) and ice hockey (in my rec. league).

Tim

Hello Tim,( Krypton), I have been through most of the planning and some building but so far, all is left to do is finish...I see the end...in a few days. I followed your tips at the begining of this thread and found when working on the noze, that it is easyer to fit the bottom part permanently and make the noze gunner greenhouse canopy removable only. I do not have pictures at this point but it is a very simple process. aligning the bottom canopy and the top one with tape and securing 4 screws to the bottom part onto the fuselage. You then remove the greenhoused canopy and you test fit the noze gunner cabin details. Once you secure the details, (I used two sided tape) You notice then that there is an approx gap og 1/8 between the detail contour and the bottom (chin) part. I placed ribbon self adhesive velcro between the two parts to secure the surrounding of the bottom part. Also between the two parts it is possible to glue scrap 1/8 ply so you can screw in the top part greenhouse canopy to the front sides. Using six of the #2 3/8 buttonhead screws. i fasten the canopy , 4 screws to the fuse and two to the sides in the joint with the bottom part. This way the fitting of the noze is always "on the noze" and makes the whole assembly sturdier. I have to learn how to insert pictures and will send some this week.

Also by doing this process, it is very windy here in montreal and my 7 year old girl came running to tell me the witch hat had flew away! Running to the emergency, I dropped the greenhouse canopy and cracked the front. (still holds in one piece but for the ones who knows me, I have a professional malformation that every thing must be impeccable, mechanically and esthetically) Tim are the parts available yet? TOPA1715 ? And since you have a priviledged position (if you have the info) they say it is an assembly, what does it include?

Also "E-power Tim" if you read this, i'm very interested in making a cut out for bomb bay doors like you are doing and I'm maybe not the only one! If you can I would like to know how you proceed, if you need to cut through the formers and how you reinforce. If you can make sort of a step to follow description. I would appreciate.

Thanx guys, I'm going back to the dunjon!

BTW ths B25 from Top flite is a 5/5, nothing deceiving, really nothing deceiving!

Tim,

Thanks so much for keeping us informed. Your help and updating is second to none. It would sure be great if all mfr's. of models would do as you have done on your own time!

Good morning.

Thanks Ken.

I can't take too much thanks for the time I have spent answering questions on this site. I have worked on many projects at Hobbico, but for some reason I am suddenly very enthused about this B-25. I guess I have just "fallen in love" with this plane and am very interested to make sure everybody has as much success and enjoys it as much as I. So you see, it is out of joy, not dedication or duty that I am writing here, so it is play not work. Our computer is downstairs where our television is and where my wife, my step-daughter and my self spend much of our time, so all I have to do is walk over to the computer during a TV commercial or when they are doing homework (my wife is a teacher at the local community college) and it takes little time away from our time together. Like right now, my step-daughter is watching TV and my wife is making coffee, so they are "doing their own thing" right now anyway and I can still be in the same room. But I have also promised to cook some bacon, so I better get going!

And right now, everything is easy and everybody is happy, but I hope it remains this way when more people are building their B-25s and begin flying them!

I'll check in again later!

Tim

krypton what is the large opaque tube for? i need to remove it for the bomb bay. so far perfect conversion. The hinge line is low so the fuse is very strong! I sanded the bulkheads and remeber the wood will be covered with sheet styrene all scaled out .




tim put those spider screen savers on and you will get more time
