WOW! (maybe watch out for the thread police after this one! Big Jim Graham is watching. LOL.)

I like the sound so much, I just built a 73" 35CC gasser because my buddy got himself a 88" 60CC gasser and I couldn't handle it anymore. LOL.

That sound is worth every penny too me.

Question - I am getting ready to maiden my PZ T28. I loaded the DX8 settings from Spektrum.

As I am a beginner, I am planning to start with the easy settings, position 2, on the dx8. But in that switch position the DR for the elevator is 47. Is that enough elevator to get off the ground. It seems low but if it will work why not.

i use a dx4e and low rates on that are sufficient - 70% travel for that radio. so you should be fine with 70%. you may be fine with 47% too - i'm just suggesting what worked for me.

RonaldJ,
I strongly advise that you get an experienced person to check the plane and possibly do the maiden for you.

If you are inexperienced and anything is out of balance or needs trimming while flying it can be overwhelming and turn a lovely occassion into a regretable one.

Brgds,
Danny

me too. Exactly what I was going to say. I love to fly in circles for several minutes in a knife edge with my t-28. It almost feels like it wants to be in a KE

Unless you have some sort of prior experience with model airplanes or a good, working knowledge of aerodynamics and basic flight principles, a wonderful day could turn into a really bad one in about 30 seconds....

Strongly encourage you to seek the help of a friend who has experience with RC aircraft before the maiden; although the T-28 is a very good model for a relatively new(ish) pilot, it's also a very capable airframe and can get away from an inexperienced pilot fairly quickly...

Not trying to rain on your parade...just trying to be the umbrella

the elevator works very well so it should be enough... but... some guidance at the field might be needed. MAKE SURE THE AILERONS ARE CORRECT! what a easy way to crash a pretty plane. standing behind the plane, move stick left, left should go up. double check that. she does not stall easily but experience is still needed. visually trim the surfaces perfectly flat and do this with the clevises not the radio. thats a good start. she flys just fine on low rates too. get her up high right away and trim her out way up there. dont mess around low to the ground. she is VERY floaty and once trimmed will almost fly herself. ALMOST!

The front small Dubro, have a tendency to bury down in the snow, or cracks when it's lumpy ground. Still thinking how to fix the problem. I have belly landing also, but it's more fun ROG.
The Dubro Snowbird are made for 4 mm undercarriage. T-28 have 2,9 mm.
Thanks Arne,
I just might try the floats off of my Flyzone Beaver.. you can pick up a set of those for around $15.

Well, I fly electric because it is nearly SILENT and anyone that adds sound to make it noisy must be nuts. If you want noise get a gasser. Just my 2 cents.

I fly at our field early in the morning with a few other e flyers and when the gas and glow guys show up I pack up and leave.

Danny, John: Thanks for the warnings. In fact there is a fun fly this weekend so maybe I will take it there and see if someone will maiden it for me.

I have checked the aileron and they are operating correctly, as walter3rd describes. I had to adjust a couple of the linkages to align the surfaces and the left and right aileron now have the same amount of movement up & down. But I am sure some fine tuning will be required once in the air. I understand these models are a bit nose heavy so I expect some elevator trim may be needed.

I have been able to master the t28d with Phoenix set on the advanced setting for this model. My heli experience should be of some help as well.

So I think I am as ready as I am going to be. But that said, I'll see if I can find a mentor for the 1st flight. If I can't, I have foam ready ca standing by. Wish me luck.

^ Just dont be in a rush to get it in the air on take off. Let it role and pick up speed as you increase the power progressively to about 3/4. Then very gently give just a bit of up elevator and it will float off the ground with good airspeed.

Be prepared to give pitch and role corrections once off the ground just in case your not trimmed very well at first. With each of my PZ T-28s I've found they want to climb slightly with perfectly neutral control surfaces with > 1/2 power. I mechanically trim the elevator linkage down maybe 1 to 2 turns from flat.

once airborn climb out at a steady rate but dont get her to steep. sounds like with heli experience you should be plenty coordinated to tackle fixed wing.

That\s what I'm hoping. As everything is frozen here, I am looking at a nice smooth private rink on a nearby river to take off on. I have lots of open space there and the smooth rink will provide a good take off and landing spot.

I just need a nice sunny, no wind day. They are few and far between.

Ronald, please DO NOT equate "mastering" the T-28 Trojan on a sim to actually flying the plane for real. Sims teach you somethings and lie to you about others. I believe you are doing the right thing in going to a club and getting someone to setup and maiden it for you. You may even get one of those folks to "buddy box" it with you. Good Luck.
