Yep it's a work in progress. I may gut what I have and see what I can do from scratch using an external battery or the Rx power if the draw isn't to much. I actually flew it at dusk yesterday. The plane flew fine and the lights were glowing, but to get the full effect of the lights, it needs to be dark, like an hour after sundown. Need to put something on the bottom to, I'm playing with my belly lander so I have to take that into consideration.

We left before it was really dark...we have these little bugs called mosquitoes down here, no Off so they ran us off. Before that we had a bunch of visitors from the burger place, that's always fun.

I had to buy a new steering arm. I then cut out the foam on the bottom of the fuselage just behind the firewall to install it as it will not fit into the plastic firewall from the front. I then glued the piece of foam back in place.

Why do they bother with the pushrod sleeves on these planes? If anything, there is way more friction of the pushrod in the sleeve than the sleeve against the fuselage of the plane. This means the sleeve basically moves with the pushrod and offers little or no benefit. The nosewheel pushrod on my T-28 (#2) is extremely stiff in the sleeve - so much so that if the sleeve were secured in place, the servo would not be able to move any more.

Is there any one using any items like these skids or any other alternative's to duct


I have been using these for wing skids in the past. I wanted to try my plane with out any gear, and just wanted an alternative to tape.
I just mounted an additional 4 skids on the belly of my T-28. I placed them in the area's that would have the highest points of contact and still keep the the plane balanced with all 4 units making an equal contact. 3 flights today, worked very well on landing's. There are 3 other skids from HC that are a little larger, I want to try these also. I will be ordering the 3 additional sizes and post the results with the new skids when they get here next week.
Is there any one using any items like these skids or any other alternative's to duct tape on the belly of a plane.

Fly Safe n' enjoy

Wing Skids 28x10x12mm (10pcs)


Wing Skids 28x10x12mm (10pcs)
Can be used for tail skids also, in place of a wheel.

So never once were we trying to fly level on final. Always decending. You just sort of knew where to turn on final by local roads, your home airport, etc. If you started to come up short you would add some throttle and pull the nose up a bit. If you tried to pull the nose up without more throttle, stall. Then once over the landing threshold, we would cut most of the power, again depending on conditions, headwind, etc. About 10-15' up give or take you'd start the flare. If you over flared you'd get the dolphin jump which isn't pretty. There was always folks hanging around so if you did this you'd have to touch and go so that wouldn't be the last thing they'd remember. Trying to think back, I believe a touch-n-go circuit took about 1/10 of an hour. Stall speed on the 150 was about 58mph if recall, the runway was about 4,000'.

In theory, they should all be the same. Either way I've botched to many landing the old way, this way is working a lot better. Keep some thorttle on, pick a spot on the ground and aim for it. On the other hand, if it ain't broke(your landings), don't fix it.
You are showing your age!
Sounds right, no flaps! 48 at 40 degrees. 152 has only 30 degrees, and measures in knots.
I missed the 150s, cause when you went to 40 degrees, it would drag in.

Test my memory:

Reduce to 1700 rpm when abreast of threshold. pull back while decelerating w/o climbing.
70mph, 10 flaps.
Turn base, mid base to 20 degrees.
Turn final, go to 30 or 40. I would go 30, 40 short of threshold before flaring.

Those are not really sleeves, they are there to stiffen the push rod so it does not bend because of the length of the push rod and the thickness of the pushrod...

49 and holding!! These were all 150's. Heck most of the Skylanes, Skyhawks, 150's, etc you see at airports were born in the 50's, 60's, 70's. I remember $13,000 152's, just a dream! What is a 172, 200k plus now? for new?

A plane was $15 an hour (including gas), instructor was about $10 an hour.

it's costing me $125 an hour, but my dad is my free instructor
I am getting a 150 on full flap with light head wind down to 35-40 on landing.

well for those that think this plane is a trainer let me tell ya a story...

At SEFF, Corsair Nut flew my T-28 and I flew the corsair... he chased me around the parkflyer area in a knife edge and then did a knife edge loop... no joke... I nearly crashed watching him!!

This plane rocks!!

That is pretty good to be able to fly around like that on a knife edge. My friend and I were just talking about this and how difficult a time we are having doing slow knife edge passes and how much altitude we are losing while doing it. We know it takes some severe rudder input to do it, but we are trying to think if the built in dihedral on the wing is making it more difficult than it should be. thoughts besides more stick time???

There is a GREAT video somewhere back in the 500 plus posts of a guy doing some serious acro with his Trojan. And it was stock IIRC! See if you can find it and cite the post# for all who are interested. Well worth watching!

CAREFULLY try this!

Dont do this with gust factor present!

I would drag in, nose high, 40 degrees flap, mid throttle, VERY SLOW.
Touch down threshold, suck up flaps, Idle throttle.
Keep all back pressure while flaps go up increase til you are full weight on wheels, brakes, no skid, nosewheel shock all but bottomed out.
Got told to not do that anymore at the club. But I was full stop in 250 to 300 feet!

I would say more stick time...I can KE but only in a straight line...Corsair Nut would be better to ask as I couldnt get away from him!!
