Acceptable Engine Substitutes for F26-6FJ Engine??

tfrielin · Sep 1, 2019

I have an Estes Nike Smoke that I've flown successfully on F26-6FJ engines. I can't seem to find them from my usual supplier, but they do have F25-6W and F30-4FJ engines that seem close to the F26-6FJ.

Are either of these latter two engines ok to use on my Nike Smoke? (I'm not entirely sure of this composite engine nomenclature).

Thanks for any input.

The F25 is very similar to the F26, the F30 has slightly less impulse, but would probably be fine as well.

Ok, thanks. Any idea why these composite engines go out of stock for the long periods they seem to go out?

https://www.thrustcurve.org is really easy to use. The F25-6 would be fine. You'd need an adapter for the F30-4 since it's 24mm and the thrust is a little low, but probably also OK.

I don't know, stock comes and goes. The white lightning is quite different than the black max, if you haven't launched one yet, it is worth seeing.

TARC teams use a lot of F impuse motors (or at least they have in the past)

When TARC ramps up thousands are ordered. Simply demand exceeding supply during the school year.
