Screws were made with sharpened brass tubes and a small screw driver or hex wrench. I still have to install receiver , battery and balance it before it can be tested. Dean

Status: offline 		Got the stacks Randy they are going to work nicely! I am happy to announce that #2 is ready for paint after much priming and sanding and number #3 hopefully will be ready by tonight if all goes as planned. I'll try to get some pics taken. #4 has been aquired by another friend who says it will be flying by June! Soooo after quite a lengthy process it seems all four will make their debut in June. Lemens are you reading this? Quit playing with those silly little trucks and get to rigging! For those of you just joining in here is number 1 just prior to completion. Will try to get new pics here too. The front was replaced with a clear front and the rest of the paint was completed. [image][/image]

Status: offline 		I'm a little concerned with their weight. Mains are nearly 1lb each which is about twice the Robart's weight. After my last experience I'm sticking with the Glennis nose wheel but the Robart mains are much lighter.

Awesome B-25

Do want to be clear though, the Robart site specs their wheel only as 10 1/2 oz (approximate) and no weight for the tire. Our main (5 1/2) is 14 1/2oz the - plus or minus a little depending on when the set was manufactured - so you are not at twice with what a comparable (aluminum wheel) Robart weighs, and you have a real rubber tire (not foam), scale detail, etc, correct tread, etc.

Thank you for your comments Dennis. This thread always needs good input.

I think the Robart web site is a little wide of the mark with their weights maybe. Actually weighing the two wheels, the Glennis main comes in at 432 grams (15oz) and the Robart main is 243 grams (8.6 oz). Given that there are two main, that is a total of 378 grams (13 oz) of extra weight behind the C of G which is not helping an already tail heavy situation.

There is no question that the Glennis wheels are far more acurate scale wise and just plain look better but I think I'll go with Robart mains for those first few flights when I need every advantage I can get. Once things settle tho, the Glennis mains will be going on.

Status: offline 		The Robart that I had here, not more than 2 weeks ago was significantly heavier - closer to 12 oz. with the tire.

The difference in weight though, should be pointed out - you are dealing with a significant quality difference. A rubber tire weighs more - period, as does the scale detail, which in itself makes the model a "miniature replica" versus a toy (in appearance), which is what we are after.

Post some more pics - and get some of yours Richard when you're done - they're looking good.

Thought I'd post a few progress pics. My weighty wheel problem has been solved by casting my own wheel covers in resin from a mold taken fron the Glennis ones and fitting them to the Robart wheel and tyre. Sort of the best of both worlds - the lightness of the Robart and the scale good looks from Glennis. It has given me about an 11oz weight saving ( us electric types are a bit obsessive with regards to weight saving!) , plenty strong enough with scale looks. I'm happy with it anyway.

While talking weight, I'm currently at 27lb with 7lb of lipos to go in the nacelles which can be moved around to balance so no extra weight should be needed and a little cowl and scale engine detail to go. Should mean a ready to fly weight of no more than 35lb - 2lb lighter than 'Yellow Rose'. I had been a little concerned that the Flight Metal might have added unecessary weight but it hasn't.

This is the first time I've used Flight Metal and it really is wonderful stuff. There is a little bit of a learning curve like most things for the first time but really does have fantastic potential. Can't wait to start using it on the Ziroli DC-3 which should be my next electric project all going well with 'Lady Lil'.

We're off to Hawaii for 2 weeks next week so building will come to a halt but I hope to be ready for her maiden flight before the end of April. Any other maiden flight stories here??

Richard

Status: offline 		Hi All

My electric 'Lady Lil' is now into her 3rd month of operations so maybe time for some thoughts on how she works.

This plane has totally rekindled my enthusiasm for this hobby/sport. Flying this thing gives me a grin from ear to ear and an adrenalin rush that I haven't had since first teaching myself to fly 25 years ago. Not that it has any vices or is difficult to fly but it is big, does fly fast in a big plane, slow-motion kind of way ( if that makes sense ) and it does use up a fair bit of sky. It flies very smoothly and just grooves its way around the sky but you have to think ahead abit and know where you are going. It is no 3Der!

House keeping bits - I've only flown a few planes that really needed flaps but they all needed a touch of down trim to stop them ballooning once the flaps were down but 'Lady Lil' seems to like a few degrees of up trim dialed in with her 45 degree of down flaps. Once trimmed like this, landing approaches are a joy to watch with no tendency at all to tip stall. I've dialed in 70% expo on the elevator to really smooth out her flying but the first time I did this I left the flair-out way too late and kissed the runway way too fast. A really good test for the Glennis undercarriage and Robart wheels but the thing that gave were the 1/2 sq undercarriage bearers - relative easy fix and now beefed up. This is the only thing I'll change when building the next one. All the control throws and C of G are as per plan and seem spot on. I've re-motored from the original Plettenbergs to a pair of AXI 5330/18 outrunners turning 18 x 10 APC-Es. These are just perfect - half the cost, quieter and very easy to fit in with no ugly bits sticking out of the cowls.

My first B-25 was covered in brown paper and this one was glass cloth and water-based poly followed with Flight Metal. Flight Metal is fantastic stuff once the supply problems are solved. Having just finished a P-51 with traditional epoxy glass I think the brown paper still has merit. It is a surprisingly hard surface and hard wearing once properly dry and not having to work in a respirator really appeals to me. It will take time to perfect a method to get a suitable surface texture and generally develop the skills to get the kind of results I want but is something I will pursue.

The only downside of this B-25 for me is it's size. It takes two people to load into the ute and altho we have a fantastic flying field and clubhouse (hosted the 2003 world pylon champs) we only have 30 active members. This means many times I go flying I'm the only one there so my poor, long suffering wife Patsy ends up coming out to help me and it really isn't her thing. My next project therefore will be downsized a bit to a 82" Corsair, electric, full 70 watt onboard sound system recorded from the real thing and weighting in at less than 20lb so it will be a one person job to load up.

Well that's my Ziroli B-25 story. I will build another one day - a PBJ next time but I'll have to sort the transport thing out first. Meantime I'll keep flying 'Lady Lil' when I've got someone to help me and keep the grinning feeling happening.

Richard

Good to hear some B-25 chat! I have not been building recently but time will allow when time allows... Will be anxious to see even more pics.

Not intending to hi-jack the thread... I have a quick question for Dennis.... I'll shortly begin building two poster children for Flite-Metal. 130" 1/10th B-24 is going to need the proper wheel and tire.

Did you ever do a 1/10th wheel & tire for the Liberator? I'm also replicating Pacific Prowler as well...both in polished FM. Figured the 106" B-25 wasn't a stretch for you...

Ed you would be better off calling Dennis, or posting an email to him. RCU has him on "awaiting approval"
status here, and it sometimes takes awhile for them to "post" it.

actually just got off the phone with him. new things to come soon from GLENNIS wheels

Status: offline 		It's nice to see some activity again. I just got back to my B25 and am working on the cowls. More like planking a ship hull. I'm nearly finished. What a nightmare. Glad that there a lot of fillers available and it will be great to apply some resin and fiberglass soon.

I am working on the restoration of a Mitchel at the Camarillo Airport. This particular Mitchel is a PBJ-1J and when finished will be the only flying PBJ left in existence. We plan on putting the Radome on the right wing and adding the hardpoints for missile's. My plan is to duplicate this particular PBJ in my model. The PBJ will be dedicated to the father of one of the members of the restoration team and we will use the squadron colors and markings that his father was in.

I have a question on glassing the cowls. Should I cut out the la
