Neil,

Thanks for posting the video address.

I had seen this video before but such poor quality it was almost not watchable and everything about the U-5 twin had been cut off.

I did see when they demonstrated the interceptors in the video there were only two.

I have opening on wing for 3 and 4 interceptor but only two, I check on the logbook and no inscription for remove the 4 at 2 interceptor on each wing ( I have the first logbook).

Anyway, like you told me this afternoon, why putting an interceptor in front of the aileron ?  The disrupted air would probably make the aileron less effective.

I remember Larry saying that they removed it because it was giving nothing.  The interceptor are great because they work very strongly taking all the energy of a forward movement.  But they do cause a lot of drag.  Aileron do their work with a smaller drag.  I would not put interceptors in front of them.

Louis,
That make so much sense it makes me feel stupid. I can see that it would be just extra weight with no benefit and I agree, it probably would make the ailerons less effective, and Frise ailerons already protrude below the wing to add drag .

I thought N28B c/n 005 was destroyed in a crash in MA in '68 but I was looking in the FAA registry and I find an expired reg for c/n 005  N28B   1955  H-391B.

I wonder if there's a wreck stored in Naples, FL  from when it in crashed MA '68, and reportedly damaged beyond repair.  It's now owned by a WILLIAM L. STUCKER.

Can anyone help with this?

I was able to put a little bit more together about the first 6 Helios.

Does anyone have registration #'s for 2, 3, 5 & 6?

Anyone know what happened to "Ole No. 2" or even what it's tail # was? edit N243B

After more crosschecking and rereading archives I am satisfied this is how it went.

But I am open to new information and perfectly willing to edit.


The first 6 crash cages were manufactured at Canton, Ma,  initially 3 sets of sub assy components (tail cone, wings, vertical tail and stabilator) were sent to Canton by Fleet mfg in early 1954 and three are assymbled there. c/n 001 N242B, remains as a factory demonstrator. June 1954 c/n 002 and c/n 003 are sold to private individuals (ref Canton Historical society), #4,5,6 crash cages are sent to Fleet mfg for assembly, the jigs for the cages were to be sent at a later date. Helio cage c/n 006 is completed by Fleet in 1954 and eventually sold in 1957 as CF-IBF s/n FML-004. In 1955 two more sets of unassymbled parts along with cage #5,6 and  tooling are sent to Pittsburg. The construction jigs and tooling at Canton are also sent to Pittsburg, where c/n 005 N28B, is completed in 1955 using parts and the cages returned by Fleet. After c/n 006 all are completely manufactured and assymbled including fiberglass parts in Pittsburg, KS.

Found this on Helio N4123D c/n 042 this is supposed to be in the log if you have a 391 with the extra slots and it had blades in front of the ailerons when the outboard interceptor  are removed.

Aircraft modified, with removal of two outboard interceptor blades in each wing (Service Modification #29; Factory Drawing SK-516)

lot of paperwork missing in a lot of Helio's
