Fliskits Deuce/Tres
Anybody ever load dissimilar motors in a Deuce or Tres just to watch it fly? With the motors canted through the CP, you should be able to load an A8 in one mount, a B4 in another and a C6 in the third (Tres) without an issue. I've seen footage of them flying with an unlit motor, so it should work.

I have a Deuces Wild. I’ll give it a try next launch. I also have a Tres in my kit storage, I just need to prioritize it for building. And, when Fliskits closed shop, I bought about 5-6 of their canted motor mounts in various body tube sizes, in 18mm and 24mm. I think I also bought one for BT-55 to use 13mm motors. I do like clusters, and especially canted motor rockets.

Plug the ejection end of the lowest impulse motor or you will get ejection traveling upward.
Or one could use an upper stage A8-5 in conjunction with a B6-4 or B4-4, or a B6-6 with a C6-5 or C6-3. One might be able to get away with an A8-5 and a C6-3

I have flown my FlisKits Dueces Wild with a B6-6 and C6-5 motor combination with no issues, it flies great and parachute ejects just after apogee. I matched the average thrust and the total burn time of both motors. I also used a B6-4, C6-3 combination, this also works great. Keep in mind that once the rocket is up to speed the mismatched thrust from the C6 after the B6 burn out will have relatively less of an effect on the flight characteristics, the high speed air over the fins exerts enough restoring force to keep the rocket flying straight. I posted about this a while ago: https://forums.rocketshoppe.com/sho...040&postcount=9

Without looking up burn time and delay, I was thinking A8-5 and B4-4. Or A8-P, B4-6, C6-5 for the Tres.
It's a simple procedure to remove the ejection charge. With the 9999% humidity we are having, you couldn't get a static discharge if you wanted one. I was having issues with my Van de Graaff generator yesterday. The classroom air conditioner is terrible and I could barely get a 1/2" arc. I get 3-4" in winter.

If the initial thrust is mismatched, the rocket might just get stuck on the launch rod. That's what I saw happen once with a Deuce's Wild when one of the motors failed to ignite.

Good point. Lug placement and length would be important to prevent binding.
