I was gifted what I think to be is an early Fox 35 combat motor, it has a straight glow plug and the square venture with a removable insert if it is to be used on preasure. My question is what size prop should I use on a VooDoo using a suction tank. I don't want it flying too fast.

Thanks M.M.

Rich, I do not mean to hijack your thread but I have a question for you. You mentioned a suction tank, can you explain this? I have a old VooDoo powered by a modified Super Tiger 35 that is suppose to fly on a baby pacifier tank for pressure but I am having trouble finding information on this. So I am interested in a suction tank. Thanks, Tim

Here's the pacifier replacements.

A square venturi Fox .35 is not going to want to run slow. If the restrictor isn't in the stack, it's not going to want to run at all on a tank. Rich if slow is in your interest, you would be far better off using a Fox .35 stunt on the Voo Doo due to better fuel draw, easier starting and less issues dealing with a tank. Installing a tank in a voo doo requires some plumbing changes, for obvious reasons, the overfill pipe needs to be removed and relocated. Veco used to make pressure tanks in this configuration in standard vent and pressure style. I'm currently flying a Half Fast with a square venturi Fox .35 and it's quite fast. It would probably 20 miles an hour slower with the .35 stunt.

Tim I used a 2 oz. angle front plastic tank with a clunk. It fit right in between the 2 ribs left of the engine. Used epoxy and caulk to hold it in place. Monokoted over the hump.
Ken I am going to try it with the restrictor, if it doesn't go right i'll try the stunt 35. I'll have to see if the mounting pattern is the same.

The mounting patterns are not the same. I know from experience. If you use the Combat Fox run a larger diameter lower pitch prop. Be ready on launch as it may want to torque in on you. Should fly right out of the launchers hands with out throwing it or running. Putting a metal tank in a VooDoo is easy once you learn to relocate the tubes. Don't go through the leading edge. Folded wing on my first VooDoo with McCoy Redhead .35 on suction. Plus keep stabilizer movement to 15 degrees each way. D>K

Thanks Dane and Rich for the info! My VooDoo was given to a friend over 30 years ago and he never flew it. After we flooded in 2016, he gave it to me even though it never was in the water. If I have it right, I need a pacifier and attatch the fuel line to it and the engine. Fill with fuel and clamp it. When the engine starts, unclamp and hold on! Tim

That's not a Voodoo!! Sneeker maybe? Looks like the pod is already there. TS

Definitely not a Voodoo.

Looks like a sneeker to me also with those rounded wing tips.
Here's a few pics / videos of sneekers and one voodoo.

So it’s a Sneeker? Good plane? Tim

No, great plane! They really work well. Great tight turns, tracks well, and comes out of a hand launch easily. You couldn't really ask for more out of a vintage combat plane. I love flying them

Dane, thank you for the information and the videos of the Sneeker. Going to order the pacifiers and see about getting this old bird back into the air! Tim
