Default Need a Cox .15 TD...

Hi Guys,
I have a 1`/2 Scimitar by Bill Evens that I'm taking out of moth balls. It hasn't flown in 30 years and though the airframe is flyable...the engine is toast. It was a rocket ship when I flew it last...and faster then most .40 size race planes of the day...probably today too.

I need a Cox TD .15 in running order...

Anyone have one...new or flyable ?

You may be able to get some parts for the old one too. The Cox Conquest is much faster but will need mods for it to fit in the same mount. If you insist on Cox, the Conquest is the best one.

Was the Conquest conceived to go head to head with the Super Tigre or Rossi

Yes, I believe so, It actually surpassed both the Supertiger and Rossi's that I had/have from that time in the unpied version. I think it was just time to update their line of motors from the 1950's and 1960's. Even the Quiet Zone and Queen Bee stuff with the mufflers and throttles were an attempt to get with the times.

Sure was.

I believe the Rossi P/L was interchangeable?

Here's a video of a bench run, this is an ABC conversion of the Conquest - this is turning a Bartels 7x3.5, this is a GF clone of the Cox 7x3.5, and was used by many in FAI FF at the time since the Cox versions worked well but would shuck blades at those levels. This is a muffled, R/C version and spins it at 23k. These are pretty respectable performance numbers.

Go to "Special engines" on this page, you can find info on some Cox .15 variants and the Conquest, and also find copies of reviews for many:

I have one that I put the Rossi piston/liner into. The Conquest In stock form, almost ran with the rossi's and the super tigre I had. The "Cossi" Young mod that you can still get done, made it almost competitive with some going into the realm of unbeatable. The one I have still runs great (just replaced brgs) Heavy for sure and a good one will turn aprox 24k on the revup 7-5 or the current apc 6.5" props
Nice engines.

T TD is much lighter and will not turn up like the Conquest. No brg's though which is nice for the weekend warrior type plane.

Did you use the Rossi plug or the the standard (?) Cox Conquest 1/4 32 type plug? I was just thinking of making a Turbo head for one since I sort of have it set up.

Thanks Guys,
I'm really looking to redo this old Scimitar like I flew so long ago. What I seek is a TD .15 in operational to new condition. If anyone has one...let me know.

Believe me...this combination was a rocket ship and very fast. It was light, extremely maneuverable and with only a 2 oz. tank...flew like its tail was on fire for five minutes.

What parts would you need to refurbish your old one?

skaliwag, That's right, rare and not cheap, but I see them from time to time on E-bay you just put in an saved search for them. If you want a real shock look at the price of the TD051 at Cox international looks like the last one.
