hi Chris,

could you outline how you attached the pylons to the wings,

Thanks

Hi James
I am actually getting ready to attach some pylons within the next few days. You can either glue them on or bolt them on. I will be bolting mine on. If you are going to be bolting yours on , you will need to glue in some hardpoints on the inside of the wing. I will get some pics of placement and how i did it, this week.

thanks
chris

First off, you will need to cut out areas on the bottom of the pylons so you can glue in some backers where the mounting screws go through. I used 1/32" thickness G10 and some 20 minute. If you do not have G10 handy, ply should be fine. I used the sandwich bag method to drip the glue down into the pylon where you will be gluing in the backers. There is a bead of glue from the closeout process inside the pylon, so you will want to put enough glue in so your backer will sit level on top of this bead for a flat surface for the screw to sit. Here are a few images.

You can then mark center of your cutouts on the top side of the pylon and proceed to drill them out for the screws from the top side. For the screws, i used #2 screws x 1/2" length.

I started with the inner pylon first so i could take an easy and accurate measurement from the wing root. You can measure center of the first pylon to center of the second pylon and so on. I found this is the easiest way to measure and make the pylons parallel with one another. You can move the pylon from front to back to see where it saddles up the best before marking your first hole to be drilled. I marked the back hole near the servo cover first on the first pylon. The pylon will be placed along side the servo cover. Once i had my mark, i removed the pylon and drilled out a 1/16" hole into the wing where it was marked. Put both screws in the pylon and screw the back screw into the wing where you drilled the hole. You can then move and measure over the front part of the pylon on center with the back part and once you have yor placement, you can screw the front screw in. Now you can measure over for the next pylon which will sit in the same location next to the outer flap servo cover.

The outer pylon will use one of the holes for the servo cover. It will also need to be aligned correctly because the aileron linkage runs through this pylon. There is no good reference point for the 3rd pylon, i just centered it between the 2nd and 4th pylon.

RE: CGRCJets A-10 Build Thread
 

After all my holes were in place, i removed all the pylons so i could glue in some hardpoints on the inside of the wing. I used a very small diameter piano wire to fish the hardpoints into place. I used 1/32" G10 for my hardpoints and thick CA glue to attach them. I drilled a tiny hole in the center of the G10 for the piano wire to fit through and then bent over the end of the piano wire and taped it to the G10. I then put Ca glue on the G10 and fished it into place until the CA set. Once the CA glue set, i pulled the piano wire with a little more force until it came free and then onto the next hole. Once all the hardpoint were in place, i re drilled all the holes with a 1/16" drill bit. I then put a #2 screw into my drill making sure it was not wobbly and tapped all the holes with it. This helps speed up the process of re attaching the pylons.

RE: CGRCJets A-10 Build Thread
 

There are a few holes you will not have to fish through, but for the most part, it was pretty easy. I used the same method to attach the wheel fairings. Hope this answers your question. Few more pics for reference.

RE: CGRCJets A-10 Build Thread
 

Hi Chris,

Thanks for the info on mounting the pylons.

I have a few more questions.
-When using Tam's mounts, are you gluing the mount to the hatch then screwing the hatch down, or gluing the mount to the inside of the top wing skin?
-How are you mounting the front Robart legs to the Robart nose retract, none of the 2 adapters supplied work with the leg/retract combo, do you guys machine up an adapter?
-I noticed on Tams jet that he has a layer of carbon on the fuse where the nose retract formers mount, is it worth adding this in?

Thanks

James

RE: CGRCJets A-10 Build Thread
 

Hi James

The mounts get glued to the inside of the cover. Tam says he just uses CA glue. The wing is to deep to mount them on the inside top of wing. His mounts come in different sizes. Here is a link to one of his mounts.

http://www.tamjets.com/original/prod...e8e196847e91fc

I had to drill out one of the adapters in order for the steering column piece to fit into it when i did mine. Tam has his pressed in and i do believe he says he ordes a separate inside reducer just because of this problem. You may want to send him an email just to make sure. Pressing it in would be a better option because you would not have to worry about any kind of play in the nose strut.

The reason for the carbon was to stiffen up the nose area to hold battery weight. When using Tams new retract setup, we got rid of some nose formers which weekend it. The carbon fiber re strenghthened that area. This way we could throw the battery weight more forward instead of adding any dead weight, plus Tams nose retract mechanisms have a direct drive steering mechanism which is much easier to set up than the older pull pull setup that we had to use with the robart retracts.

Hey Chris!
I came over here from RCG and I am at Tams website also regularly too. I didnt start on mine yet, but did receive the Map retracts,struts,wheels,brakes,cylinders,failsafe etc... All look totally awesome. Tam and John at MAP done a wicked job. Now I am waiting for the two TJ-110 fans.
Whats the news on the weapons and cockpit kit? I dont want to read through this whole thread just yet, so sorry if I missed it. O have been away from RCG for a while now and will not go back...EVER! Let me know when all these are all available so i can load mine out to its maximum payload carrying capabilities. An A-10 just isn't an A-10 if not full loaded out. LOL!!!;):D

Brg, Joe

RE: CGRCJets A-10 Build Thread
 

Hi Joe
Tam did a great job with the retracts. All set up and painted ready to go. Im still waiting for mine for an ARF i did for a customer. After wasting all that time on doing the ordnance with molded nose cones i decide to do them fully molded. Much nicer and saves some time for you. I am going to finish the second half of these molds today and hopefully have some pulled parts mid week, next week. As for the cockpit, i just need to finish the dash. I am still tossing around how i want to do it ,so it has a nice scale appearance. I guess i need to stop thinking about it and just jump to it. It will be very soon but I will keep you posted.


chris

RE: CGRCJets A-10 Build Thread
 

Fantastic!!!! Go for it! Dont worry about it all, you will make it awesome either way.

RE: CGRCJets A-10 Build Thread
 

I try but my pickyness takes over and wants to slow me down. I need to slap it in the face and put it in check. Wait until you see the ARF i am doing. You may want to package yours back up and give it a round trip. Heres what it will look like.

Chris, Any pricing on Tams A10 gear? Wayne

RE: CGRCJets A-10 Build Thread
 

Hi Wayne

http://www.tamjets.com/original/prod...1418efb914f68b

I think he is also offering them cheaper unfinished. If you were to buy the robart retracts, i think they come in around the same price with Tams wheels and brakes. Tams wheels are tuff and alot of other wheels we used on the A10 only lasted few flights before falling off the rims. I would definately recommend his whole setup because he sets them up very nice and they look great on the A10. His steering mechanism is also much easier to deal with.

chris

RE: CGRCJets A-10 Build Thread
 

Wayne
Have you had any progress on yours? If you do decide to go with Tams gear, i can send you out the new nose formers for it along with some carbon fiber. Also, John and lowell sent out wingtubes that were to short with all the kits they had, so i will need to send you a new one, along with whatever else you did not get. Please let me know, and i will get these out to you as soon as i can. I am still playing catchup , so it may be a bit before i can get them to you.

thanks
chris

RE: CGRCJets A-10 Build Thread
 

Chris do I have all the newest parts and upgrades in my kit???? I need to know if it will all work ok with the MAP/Tamjets gear and stuff. I just want to make sure it will all go smoothly cause I see that some are getting new wing tubes,formers,carbon fiber reinforcements etc...... Let me know.
Joe

RE: CGRCJets A-10 Build Thread
 

Hi Joe
Yours is fine. Wayne recieved his kit from John and Lowell. The wing tubes they distributed with the kits back then were to short. Nothing has been modified besides the nose formers for Tams retracts and that was around the time you recieved your kit. I may need to send you out some carbon fiber to stiffen and strengthen the nose area seeings you are using Tams retracts. Tams retracts enabled us to get rid of some of the nose formers so battery weight could be moved into the nose area and simplify the steering from a pull pull to a direct. Now that the formers are lost, carbon fiber is used to re strengthen the nose area. I am still awaiting some retracts from Tam to arrive ,but when i get them, i will post some pics so you can be certain you have the right formers for Tams gear. Oh, and get started on that thing would ya. I have the weopons molds finished now but came down with the flu this last week so i have not made any parts yet. Ya cant put them on until the plane is done.

RE: CGRCJets A-10 Build Thread
 

Thanks for that tip, very ingenius !

RE: CGRCJets A-10 Build Thread
 

No problem Ahewitso. Here is another tip for the cannon. Maybe it will speed up the process for you that are building. I will be cloning the chrome cannon like the picture above to make the scheme accurate.

- 3/16 brass tubing from k&s engineering

- I bottom out the tubing in my chuck and dont ask me why, but it is the perfect length when cut flush with the prongs. Im sure other drill may be different but i guess i purchased the right one.

- I then take a hacksaw blade and clamp it down in a vice

- Start the drill up and use the prongs on the drill for a guide to cut it flush with the prongs. I use to use a small pipe cutter to cut these but they end up flared. This method cuts the tubing faster and insures they are all the same length.

- Walla, now you can take your new barrel out of the chuck.

- After cutting off both opposing ends of the tubing, you can clean them up on the belt sander and get it ready for the next 2 cuts.
