Did some mods to my T-28 and want to make a thread for all the brilliant ideas of the people in this forum to make a good plane even better.
Feel free to post your improvements.


Here are some photos to show my mods - pictures tell more than thousand words ...

Thought that the nice air intake at the bottom has to be made usefull



Has to be painted...



I use the incoming air to cool down the ESC



Some changes to improve the air floating



to be continued ...

Good idea. I guess that's why real cowls have air intakes.

Good idea

Good Idea

But also needs a little air filter, to avoid dust and possible bugs in the engine room :-D

I think I am going to add this to my T-28

Another good improvement:

Change the wheels. The following wheels fit perfectly and landings are very smooth and you get also some suspension (probably good for the retracts):

One Note: The standard inner diameter is 3mm. You need to take a 5/32 drill and drill it to 4mm in order to fit on the stock retracts. Also those wheels a bit heavier than the stock.

hiya what did you use to open the hole up for this mod and what size did you open it to. also did you make any holes further along in the fuselage thanks

I used a hot solder and careful drilled the hole.

I've order the following Struts:

http://www.sonicelectric.com/Merchan...de=ERS-Strut-F

As soon as they arrive, I replace the stock struts with these. The only things I'll use from the stock gear are the metal rods. I'll shorten the rods to the right length and mount the new struts. I'll report here again - incl. step by step pictures

As I told before, here is the Building Report.

Steps for the wing struts

1. Remove the cover of the orig. struts and wheels.
2. Remove the plastic-blindness by the metal-rods with a Dremel. Be carefull, that you don't demage the metal rods with the Dremel.
3. Shorten the metal-rods and push the new struts over the metal rods. Check, that the struts have the correct height, and consider that the two
maggot-screws grasp. It doesn't matter, that the drilling of the new struts are 5mm and the metal-rods have only 4mm outer-diameter, therefore it
holds as long the maggot-screws are solid fastened and secured with screw locking varnish.
4. Install the wheel, also check that the whole leg get in properly (because of the length). I had to cut a little foam out.
5. The most difficult now is to reconnect the Strut Cover (the long slice) to the new strut, since no mounting for the linkage is given on the new
struts. I use a cable-binder (large) and connect it to the new strut. After that, I pre - drilled a 1mm bore in the "head" of the cable-binder and
tighten in the screw for the ball head. Secure the screw with super glue (respect not the ball-head sticks together)
6. Reinstall and align the strut cover, so that nothing sticks and the cover also closes right.

Steps for the nose wheel
1. Execute step 1 to 3 from above.
2. Remove the linkage of the baydoors, and the baydoors itself.
3. Remove the steering linkage (solve maggot-screw first) and the adjusting ring underneath. This adjusting ring is no longer needed.
4. Mount the steering linkage exact to the same place, as the adjusting ring was placed. Take care, that nothing sticks, otherwise the nose wheel
doesn't gets back in the bay properly. Therefore, I have to bend the steering rod a little bit to avoid sticking at the mechanics/electronics
housing.
5. Reinstall and align the baydoors and hang up the linkage.

Because of bad weather, I couldn't make test landings. But on ground testing, the suspension struts makes a very good impression and even works
perfect.


The Wheel Covers are actualy not install, cause I must find a solution for how to fix it on the struts.


Summary: A modification, which is worthwhile.

I hope this report, will be useful.

That is so good!

Have you flown with this mod yet? I'm kind of curious if the air blowing through that hole is enough to blow the cowl off. I plan on doing this mod as well but was thinking of making another hole further back in the fuselage to let the air blow out.

I did the same mod and it actually is a perfect location for the hole. No aerodynamic differences and the ESC stay's cooler. Also it looks very scale since it uses the intake on the cowl that is designed for it.

The cowl itself is heavy plastic and secured with three screws. The air is already streaming into the intake of the cowl regardless - but with this mod it actually has meaning :-)

Oops... I actually meant the canopy. I don't have the plane yet (I do have the Dynam version and the Airfield 800mm one) but is the canopy held on with magnets?

Magnets and plastic retainers.

The cockpit is actually pretty tight connected to the fuselage... If you don't trust the stock magnets you may want to replace them with Earth Magnets - That's what I did - uh another Mod :-)

Sweetness...thanks for the info! I just ordered the grey kit that NP has for sale for $149 since I have everything else laying around on my tool bench. Can't wait to get it!
