Posted 14 Jun 2017 One thing I would maybe be concerned about is the paint on top of the cap strips. Unless you ribstich the fabric, the fabric is glued onto the 1" cap strips on the ribs. (Actually it's fine to glue and ribstich) My concern is will the MEK solvent in the glue lift the paint and give a poor attachment to the rib? (that is, if you are using poly fiber system, although the concern is valid with other systems as well) Like Ed mentioned, usually bare wood is best on the capstrips where the glue will attach. Actually same goes for trailing edge and front spar. JImChuk Share this post Link to post Share on other sites

Posted 12 Oct 2017 Firewall rebuilt, Motor mount mocked up. Has been a challenge, The Hirth F30 is a big engine for this plane...... Share this post Link to post Share on other sites
Posted 12 Oct 2017 Looks good makes me wish I kept the motor . That plane is going to be fun to fly that's for sure . Share this post Link to post Share on other sites
Posted 23 Oct 2017 Motor Mount primed and painted. Tin installed for firewall. Need to buy a prop, figure cg, battery placement, ect...... Share this post Link to post Share on other sites
Posted 23 Oct 2017 With a 582, your CG would probably end up near the front of the envelope. With the heavier? engine even more so. I would make a provision for mounting the battery as far back in the tail as you can. JImChuk 1 person likes this Share this post Link to post Share on other sites
Posted 24 Oct 2017 Yeah I intend to put the battery as far back as I absolutely can. I chose a motorcycle battery that was used to start equivalent cc engine. So it's not that large. I also have 5 gallons of fuel that's just behind the trailing edge of the wing. Will be interesting no matter how you look at it to get it balanced Share this post Link to post Share on other sites
Posted 24 Oct 2017 Actually the hirth is close in weight to a loaded 582 . It'll be close but you shouldn't have any problems with cg . Share this post Link to post Share on other sites

Posted 6 Feb 2018 Making progress. Landing gear will eventually be replaced, one is a original and the other is a new one. One wheel is about 2 inches farther forward.....The wing tUpdate....Continuing along. One wing ready for paint.

Posted 12 Feb 2018 Great progress on your Avid! Sorry I am so late to comment on it; I have been pretty involved in building new wings and getting ready for a motor change on mine that I have not been on the website much and was not aware of your post. I'll PM you, we need to get together and see each other's birds since we are nearly neighbors.Will talk soon,Randy Share this post Link to post Share on other sites
Posted 12 Feb 2018 Looking good. I do have one thought though. With the sticks being straight I don't think you will be able to get full deflection on the roll especially if you have a passenger. They are curved and offset for a pretty good reason. I do have a spare stick and a tubing bender that will bend them without deforming the tube so I could make a couple sticks for you if you would like. I would hate to see a lot of work go down the shitter and you get hurt because you could not get your leg out of the way to give full input on short final and a gusty cross wind. Mine only had 1 stick when I got it and I tried using a straight stick on the passenger side so my son could fly... that lasted about 1 minute into the flight and I pulled the pin and the stick.That leads me to thought #2 on the passenger stick using a quick pin to hold it in will make it really easy to the passenger to get in and out and put the stick in place once in the seat. Or if its a larger person with meaty thighs you can pull the stick and shove it under the seat.I am very interested in how it performs with that engine as well. Akflyerbob has one being rebuilt at the factory right now to put in his Mod II KF. I am hoping it perfroms like I think it will! Keep at it, you are getting close to getting her in the air.

Posted 12 Feb 2018 Dude...The amount of (quality) work you are getting done and the speed you are doing it amazes me. I am jealous. Your shop isn't bad either :-)BTW, how difficult was it to remove your spar stiffeners? I'm about to tackle that on my plane. I want to replace the existing stiffeners with longer to hopefully reduce wing flex.Thanks!Chris Share this post Link to post Share on other sites
Posted 14 Feb 2018 (edited) Well that is looking damm nice and fast work. My KitFox is comin along well also. By the way is ur lookin for some Avid A parts i have one here im parting out, (with 3 KitFoxs #0021,0038,0048 i dont need to build the Avid, have set of builable wings,doors,flaperons,turtledeck,cowl,fuseloge w/tail cut off but have tail,control surfaces,think a set of gear,wing struts w/wood farings, and lots of mis parts, cockpit control stick and linkages, foot controls if anyone lookin for stuff its all cheap or trades work to, and i belive Avid A build book/paperwork planns Edited 14 Feb 2018 by Buckchop Share this post Link to post Share on other sites

Im not sure about quality.....This is the first plane ive ever done. Im cutting my teeth on this one. Its a learning project. Looking forward to building a bigger plane. Trying to save every dime i can. Paint is rustolium enamel. I experimented with catalyst from super flight. it worked to my surprise. I just rolled it on. did not feel like spraying.....

Do you have a opinion on props, 3 blase vs 2 blade brand, Ive been really looking at ivoprop.I will get on it when I get home then. I am torn right now. I love how smooth the IVO runs but I keep hearing from guys that say the warp pulls harder and the kool prop discussion on here really has my attention. I am really thinking of getting the kool prop and trying it out to see if its really that much of a difference.I tried mine as a 2 and 3 blade and the 3 blade was much better. Opinions on this varies. Share this post Link to post Share on other sites
Posted 15 Feb 2018 What I like about the Ivo prop is if you have a 3 blade and you ding one you can change it to 2 blade really easy Share this post Link to post Share on other sites
Posted 15 Feb 2018 What I like about the Ivo prop is if you have a 3 blade and you ding one you can change it to 2 blade really easyDon't you have to have a 2-blade hub to do that? You could do the same with Warp Drive and 2 hubs. EDMO Share this post Link to post Share on other sites
