4 stroke good for Quickie 500 kit?
Hello,
I've got a Quickie 500 kit from old school model works, and I want to know if a four stroke glow engine would be practical for it, or maybe I'm better off with a two stroke.
If a four stroke works, what four stroke would be comparable to a .46 two stroke in terms of wight?

That’s a tough one. That airplane typically builds nose heavy with a .40 2 stroke. I’ve got a Super Tigre S40 on mine and had to put 6oz of weight in the tail to balance. This is after making a hatch behind the wing for the receiver battery. With a 4 stroke you would need to extend the landing gear to which is a weak point. On a hard landing, the gear flexes back and the wheels hit right on the wing spar.

That's what I was concerned about. I'll probably look for two strokes in that case, but I've seen one quickie 500 with a four stroke, so it would interresting to look further into this.
But thanks for the advice

If the kit you have is built anything like the original Spickler kit I would say the fuselage is fine as is. You can replace the 3/16 tail pieces with some denser balsa and pin the tail section in place. I would move the firewall back an inch to help with balance but keep in mind that makes installing your fuel tank more difficult. Make a hatch behind the wing for the RX battery. The wings should be OK except on the original kit, there is no dihedral brace. On mine I just glassed the center. On anything faster I would add a brace to the third rib and glass. Here is a picture of mine, built from a 1980 original Spickler kit.

Thanks for the info, it really helps.
And your plane is really cool. I'm thinking of covering mine red or yellow and adding a black and white checkerboard pattern underneath.
I might stick with a .46 two stroke, as that was what was recommended by the manufacturer of my kit for the stronger option. Besides this is my first kit, so I should probably keep things a little more simple, but brainstorming ideas is a great way to get more insight, and you can never have enough insight in this hobby.
Just curious, what size of glow engine are you running? looks like a 40 or 46.

FYI - for many years we had a very active racing circuit in my area flying them with .28 two strokes (Webra was the hands down favorite). With an 8x6 prop, and the lighter weight, still plenty fast. Meant as a less expensive introduction to Q500 racing, with any easy update to the somekin' 40's the big boys were using.

Thanks for the insight. Knowing .28 engines work well is nice
l'm sure I'll find the right engine, probably between .20 to .46. What would be a good pick for two stroke .40?
