I have recently bought an ultra micro T-28 Trojan. I have been flying my champ for months now, and decided I was ready to move on. People at the local hobby shop reccomended the Trojan. Also, I have seen that on many forums, people reccomend the Trojan as a second plane after the Champ. Anyways, I really have no idea what to expect when I fly this thing. I don't have a simulator either. So, have I bitten off more than I can chew? Possibly tips on how to fly it?
I have the micro Sukhoi SU26xp, and I really have to argue with myself to wait for "No Wind" conditions. You get anxious to fly and where I live days with no wind are few and far between. It really takes some patience to not put it in the air when it's a little too windy. That's my first suggestion.
Second, go over it a couple of times looking at the lines and make sure the trim looks centered up and things like the rudder and elevator are straight. You don't want any surprises with trim on the first flight. I am sure there will be some adjustments as there always are, but hopefully you can keep them to a minimum.
Third, take it easy on the first flight, even if it's just a takeoff, circle and see what the final approach looks like. I have been watching a few videos on youtube and I am seeing a lot of people who tend to go full power and when things get a little squirrely just keep the throttle wide open. It tends to end in a plane augering in. Get it in the air and then slow it down a little. No need to stall it out, but you don't have to rip the wings off either. Make a few circles and get an idea of how it's going to fly and then start preparing for your landing.
It should roll easier. That might make it a little less stable for you as well. Not sure if there is any dihedral build into this model but that would help compensate and make it a little more stable. Just try and take it nice and slow the first couple of flights and get a feel for it. Then you can start wringing it out.
It's all down to contriolling the 'nerves' before the flight. And remember you are not alone with this. Myself anf many others who have been at this for more years than we care to admit - STILL get nervous on first flights of models .... I'm even bad when a new flight area !
On to Low vs High wing ...
Look end on to both. What do you see ?
High winger - the transverse line through the model wing tip to wing tip is HIGH and the weight of fuselage is UNDER ... creating a stable pull down. As long as wings are evenly balanced - the plane will hang with wings on top.
Low winger - taker that line again and as long as you have reasonable dihedral - the line through will be somewhere through the fuselage BUT now there is a diovision of the fuselage weight in terms of above or below that line. This reduces the stable pull down into a PUSH and PULL down and also can effect a flip over so that model wants to hang upside down. This is main reason we balance for CoG with model inverted.
The worst of course are the near zero dihedral low wingers for aerobatics etc. and is also why many aerobatic machines are MID-wingers to compensate.
Lets move on ... high wingers even flat wing no dihedral will be more stable as the weight is below wing ... Low wingers can be stable though and that is down to interaction of surfaces, design of aerofoils, placement of gear, lateral and longituidinal balance ... and of course some dihedral.
At end of day ... the T28 and it's cousins are good stable low wingers and should prove a good follow on machine for you ... accept that you'll be nervous .. get out there and go for it. Enjoy !
- check the center of gravity! a little too far forwards is much better than a tiny bit too far rearward
- make sure the control surfaces are trimmed to 'neutral'
- hardest thing to get used to in the first 30 seconds is that you need to keep the wings level, it will not level itself like the champ
- it does not need as much throttle as the champ to fly just fine, it has a more powerful motor. will cruise fine on 1/2 throttle.
if you crash it at anything less than a powerdive it will pretty much shrug it off.
Ask me why your DX5e is doomed... and how to fix it.
