Status: offline 		In building my ZP38 I am at a point in the center section to install the flaps. I am not doing fowlers. How many have used the internal linkage method shown on Ziroli's plans and do they work well. I've seen a couple of pics of others planes and they have the servos hanging out the bottom of the wing. Is there a problem installing them internally or did they just go the easy route?

Status: offline 		A servo on each flap was my plan, the way I interput the plans is with the servo and linkage inside the wing. I have a PCK laser kit and it comes with ply flap horns. I am considering replacing them with aluminum ones that I will make using the ply ones as a pattern, or do you think the ply is ok. I have had ply horns break on me before

Status: offline 		the internal linkage as shown on the plans work fine as long as the horns are made from aircraft grade ply the holes will not develope excess play, if you make them from metal then you have to worry about metal to metal contact causing possible rf noise.

Status: offline 		I will be using ball link type connectors such as Rocket City through out the whole plane, in 4/40 of course. That should help to eliminate the RF interferance. The PCK horns are aircraft ply, I just have a trust issue w/ply horns. Been there, crashed that.

Status: offline 		I am about the same place you are in construction. Have decided to do ball link connectors as well just like I always do. Have been undecided about the Fowler flaps and was wondering why you decided not to go that way. I am leaning against also just because of the added construction time and I'm certainly not headed to the scale masters anyway.

Status: offline 		I built my ZP-38 per the plans with 4/40 pushrods and Sullivan clevices of all 4 flaps. One servo per flap. 4 years and over 100 flights and never had a problem. If I had to set it up again I would use a JR Matchbox. What a pain it was seting up 4 servos to all work the same. PS use a high tourqe servo if you want them to come down under a load. Mike

Take a look at the bell cranks sold by Nelson Hobby. They are made of T6 aircraft aluminum and use the Rocket City 4-40 ball link. They have two ball bearings that the mounting bolt swivels aroung. They are very strong and slope free. They come as a kit that you put together.

Status: offline 		K_sonn, those are some cool looking bell cranks, I'll keep them in mind, however I am doing plug in wings so will need seperate servos in the wing panels, Might could use them in my mock p38 trainer though.
Luckyb001, enlighten me on JR Match box please. I have hi-torq servos for the whole project. Most are 100 oz, a few 80 oz. Also planning to run 6 volt packs for the servos.

Status: offline 		JR has a electronic device called a Matchbox. It will allow you to use up to 4 servos together and set the travel and endpoints for all 4 to be the same. A Friend of mine just used one to set up a plane and he said it worked great. You can also reverse servos if you need to. I have not used one yet but it would be great on a P-38. Mike

Status: offline 		Matchbox can be purchased direct from Horizon or any dealer that handles JR equipment. The unit has the option of using it's own battery but that is not required. If you do not connect a separate battery pack, it simply uses the receiver power supply like any direct connected servo.

Status: offline 		Does it munch much power, I spent most of today dinking around with the flaps in the center section of my P38. used a servo reversing y-harness and lots of adjusting trying to get them to move the same, can envision the nightmare when I add the outboard flaps to the mix, Matchbox is sounding better every minute I work on these things
