If you are on the ground at that speed you are doing something wrong, and if you are trying to land at that speed you are going to have all kinds of problems......

I don't know what speed we are doing with our CF at take off, but at 5400ft on a 80deg day we use all the 600ft of runway to get it the air with a JC120sx. I have seen many wheels come off jets that were not glued on.

I never use more then 250 -300 ft without TO flaps.
Our runway here at Timpa is 750 ft. I start my take off roll near mid field and am off way before the end of the runway.
I have never lost a wheel or tire. I have never glued them on. I bought them from Dreamworks almost two years ago.
I can't explain why, Maybe I am one of the lucky one's.

the Flash sits with a slight negative AOA and full thrust pushes the nose down during the takeoff roll, this makes it hard to rotate if you're waiting till flying speed to put in back elevator.

Guys,
Anyone recognise the make of these wheels. I lost the tyre, yep neither my caller nor i saw it come off. The rims don't come apart so im not sure where i can source a replacement tyre.
Any assistance appreciated.

Hypothetically speaking, it would take several laps to pull ahead of the highly exaggerated 120sx posted above......my best guess on the above post was their radar was in KPH not MPH, if that's not the case is there anyone willing to trade their 120sx for a 40 lb K170??

RE: C-ARF Flash Build Thread for All Flash's being built this winter
I am in the process of deciding how to mount my 16 oz (two) Dubro smoke tanks in my Flash.
I plan on putting one on each side of the fuse.
I do not want to rest the tank on the main tank in order to allow the main tank to expand when the tank is full.
When I put the tank as close to the fuse side as I can the bottom of the smoke tank can only rest on one inch before it overlaps the main tank.
Not enough to secure the smoke tank.
Placing a 1/8 plywood platform below the smoke tank will raise one part of the smoke tank slightly above where the wing rests on the fuse mount as I plan on using Velcro to secure it.
I have seen pictures where someone has mounted this type of tank before with success.
Any information would be greatly appreciated.

Saw your request on the UF thread, don't think we really get what you are asking. I think the pictures you remember were on the UF thread (when it was back about building!)
The tanks are not going to go far with just Velcro, as long as you stop the forward and backward movement, sitting between the wing and fuse it will be fine.
The fuselage tank only blows during filling, once full the bottom does not go much below the wood cross mount

Thanks Dave,
I saw the pictures somewhere back on one of these two threads.
I agree forward and aft would work fine. My concern is the tank moving to the center of the fuse where it would block the inlet air.
I guess it won't hurt to attach it partially to the bottom of the main tank then with velcro also.
I will give it a shot.

Should be fine, you can always glue some 3/8"high "stops" inside each tank. But don't think you are going to need them
Blocking the inlets will only slow her down, turbines breath from any gap available!

the pic's were of Douggy's old classic flash and my classic flash, they are just Velcro'd in, it works great. the wing holds them in place in flight and the Velcro when the wing is off.

My good friend and flying buddy has the classic flash unpainted and wanted the red, yellow and black colour scheme of the ultra. I took some pictures of how i did the masking as it may be of some interest to others. Another benifit to doing this is you get rid of that 'orrible' seam !

Now that looks great! Actually suits it, I guess the F stickers warn people before you take off
Nice job!

I recently started on the cockpit on my flash, and followed the great advice from this thread. Just need to paint a few parts and install it, I'm just wondering if everyone has been gluing the cockpit in or making them removable? I ended up using the global f-18a cockpit and parts of the carf flash cockpit.
thx
thx
