Status: offline 		Thanks for the information Gary I was trying something like that using standoff mounts for the engine but never realy came up wiyh the right measurement the same should work for me with a G-23 that I ,m waiting to recieve back from Horizion repair center. They rebuilt it for me for 80 bucks, It should be at my door step any day. Did you have any trouble mounting the retracts?

Status: offline 		Thanks for the info Gary. Here is a possible solution for the large four stroke (1.50, but the 1.80 should be the same.
If the engine is mounted in the 7 o'clock postion (looking from the front), reverse the carb (remove two screws and rotate 180 degrees), then loosen the attachment to the head and turn the carb body and intake about 20 degrees clockwise (if looking at the engine from the rear). The carb body should then be sitting with the needle valve sticking right out the side of the of the cowl and the throttle arm will be right under the tank and above the retract unit. You will still need a 90 degree exhaust adapter, but that should do it. More to follow.

Status: offline 		Gary have you ran the engine enough to know if the cooling fins that had to be removed are going to interfier with the engine running at the right tempature or could it possibly run a little hot? B&B specialties has a header pipe that they say will fit inside the cowl on the T 28 without having to make any cut outs for it. I will purchase one of thesae for my plane. Are you using the retracts from Cox?

Status: offline 		I beleive Darryl at Sierra Precision is making the "scale" front strut and mechanism for the T-28. I know he has a kit and is doing his own research in to fabricating a set of gear for the model.
I have some of his stuff in my jets and it is top quality stuff. A very nice guy to talk to and very knowledgeable.

Status: offline 		Hello all T-28 fans . WE flew the T-28 for the first time yesterday! The plane needed very little in the way of trim. It takes off form grass quickly with about 15 degrees of flaps. Make sure you use the differential ailerons as described in the instructions. This makes the plane not skid into turns. The plane flys very well at the low settings. I thought it got squirley at the high rates witout expo. Final dual rate setting was 60% of high rate on ailerons (very effective) and 70% on all other controls. I can not believe how slow this plane lands with full flaps. roll out was about ten-fifteen feet! SWEET! May have a video soon of the first flight. flew it four times with nothing shaking loose. The G-26 flew it effortlessly at half throttle with a Xoar 16/8 prop. Things turning 8575 RPM. This plane would be an excellent entry for Fun Scale competition. You have a complicated aircraft, i.e. retracts and flaps that just about any one can fly with a good start with a trainer. Great second plane, and can be flown with fixed gear. I did get a copy of the new manual and the retract instructions are very easy to follow. Cox Pica has a winner. You can not build the quality of model they are selling you at that price. The paint is excellent and the cover job is also excellent. The new owner of the plane had not planned on this being his first plane to fly this spring due to him being in the hobby only a short while. After about five minutes on the sticks he became very relaxed with the model. He did most of the take offs on the plane. That sums it right up. He can't wait to fly it again. I told him once he flies it it will become his favorite plane. I'll have to call his wife to see if that big grin is off his face yet. LOL
Good Day

Status: offline 		OK guys I have the video, and need help posting it. The video is a little grainy, (one pixil per half acre) and remenber this is the unedited first flight. Went very well.

Status: offline 		Thanks for that report Gary. I knew this one would be a winner...it sounds just like the old one I had. And yes that plane was a lot of work to build back then...somebody will say they CAN build it better but they will be blowing smoke. There are very few builders that can replicate a factory finished model. I need one of these bad but already have 5 or 6 or 7 boxes waiting to be opened...the wife would rightfully kill me...maybe just one more!

You know you have too many airplanes when you don't really know how many you have.

Status: offline 		Just beautiful Gray, glad everything went well. Should get the Sierra gear tomorrow for mine and Horizion is shipping me a new G26 because they could not repair my G23. a mere 90 bucks for a new engine . Once I get everything togther I will start working on mine. Called Cox and asked them for an updated version of the instruction manual and they are mailing it to me. I dont think I will need it but why not have them send one. Cant wait to make the first flight on mine.

Status: offline 		http://youtube.com/watch?v=K46cPv1Dca0 Here is the address. As I said before very grainy. Camera was set on low pixel rate. When I took off the plane was at half throttle, and plane was set at high rates. Once I lowered the rates the flight smooths out in the first circuit around the field. I try to fly scale planes at scale speeds. I only did one high speed pass as you will see. Most of the manuvers were done at half throttle.
Good Day
