Re:New .12 Rigger Po-Boy WIP
Heya Eric! Looking good. I like your bullet tub. I would use a .150 flex cable set up. You will be able to spin a
215 with no problems. If you go any bigger, for example
the 220, you will go faster, but it will throw it around in the corners. I'm gonna try an H4 with my Hammerhead next. I will let you know how it goes.
If you want good consistant launches and a nice plane at full speed, I would make the angle of attack on your
front sponsons 4.5 degrees, and the rear sponsons should have 2.5 degrees plus or minus one. Run your
prop shaft so the bottom of the shaft is 1mm above the
running surface of the rear sponsons, and put your strut at 1.2 degrees. You are gonna love it
Keep us kids posted now. By the way! Thanks for the article on the BUD. Mine is still sitting on the sill of my living rooms bay window. I have to get it out of the
decoration mode here soon. Your article will help me get
it going. I already bought all the radio box stuff I'm gonna need. I decided to tear out the guides for the rods replace them with 7mm aluminum pipe and use accordian boots for the rod seals. I made two auto bailers, too. For the hatch, one of my buddies got a Bud at the same time as I did. He said, that his biggest complaint was the hatch being a pain to put back on after he got the engine started. This is what he did, it works great. I'm gonna do it, too.
1. He epoxied really thin walled brass pipe over the threaded studs that come out of the hull
2. He drilled the holes in the hatch to match the covered studs.
3. He cut 2 pieces of airbrush compressor hose about
3/8 of an inch long. (He had red hose)
4. He used a cupped bit and bevelled the upper edges of the covered studs.
5. Put the hatch on, and slide the hose over the studs
Takes 3 seconds to put the hatch on and secure it.
