T-28 G/S engines
I have built 2 of these. One wutha ST300 and one with a Z23. The 3000 had plenty of power but it never idled well. The Z23 ran well but was a little low on power. Needed a long take off run even with flaps. If I was to do another I would use a Fuji 32. I am running one now in a PAC GeeBee Model Y 82 " and its great.

Thanks for the info...
Another quick question based on your experience what retracts you recommend?
I noticed there were several avialable.
Thanks again.

G'Day Hircflier,
Like you I've just started the continuous weekends, it's great !
Maybe your T-28 is much bigger, but I used a Saito 170 R3 radial in a CMPro 70" FW-190. It was a perfect match for the model and fitted neatly inside the cowl with about 1/2 " to spare around the rocker covers.
Not cheap, but it sure looks good, and the sound ..........

This one is 1/5 scale weighs about 12 to 14 pounds.....but the way I build it will probably come out a couple pounds heavier.

I have a OS 160 mounted straight up in mine, it clears the cowling ( shortest head cylinder available) and still gives you space underneath for the retracts. I used a j-teck pitts style exhaust. It required some modification like removing the exhaust stacks and making a single exhaust tube straight down. I use a three bladed graupner prop a 15 x 10 and I couldn't ask for better performance. Flies like a jet at high speeds and slows way down with flaps to a crawl. If you go with spring air make sure you use robart struts and use drill rod for your wire anything else and you will be fixing gear all the time. If I had to do it all over I would go with as heavy a robart strut I could mount.

Thanks for the info......I think I will go for the Robarts still looking on engine tho.....I really would like to use gas mainly for economy, I guess, we pay a lot for glow fuel. Our gas is up to 1.79 now and climbing

RE: Pica 1/5 T28 Engine Ideas
I´ve got a similar question
my t28 1/5 scale WS 2057mm = 81 inch is about 4,5kg = 10lbs covered, incl. spring air retracts but without any rc-components.
but what engine?
a supre tigre s3000 is waiting for performance a home but I think this one is much to strong and the 2s sound will not fit to this fine plane.
any ideas/experience for a got performance 4s, throwing an eye already to saito fa120 or 150 or maybe os fs120.
how about the flight performance with a 120 4s?
is there enough space for the big 4s cylinder in the hood?

RE: Pica 1/5 T28 Engine Ideas
Theo,
I just sold my pica 1/5 scale t-28. It weighed 14# and had a YS 120 for power. The engine was marginal for power. I would recommend a Saito 150 or 180 depending on how much your plane weighs. I used Springair retracts which were originally sold with the kit. I would use solid gear struts as the wire ones bent a lot. Springaire now makes them. I have a set of Springaires in my Hanger 9 150 size P-51 and they work great.

Hi Bob S
my t28´weigth is about 4,5kg = 10lbs covered, incl. spring air retracts but without any rc-components. of course dep. on engine i hope it will not be more than 6,0kg = appr. 12lbs ready for take off.
YS120 ? if you mean Yamada engine i can not compare, these are not sold here in austria. can you give some figures and performance-datas about the YS120?
what about the installation - did you have to cutout your hood?
many thanx for help

Theo,
I believe Yamada makes the YS engine line. I feel the YS 120 is 25% more powerful than an OS 120.
I think you are going to have a hard time coming in at less than 14# with all components installed on the
T-28. I had to make a small cutout in the cowl for the front of the valve cover with the engine mounted upright.
As I said before, the 120 wasn't enough power. Try something bigger. With the YS 120 the plane would struggle to takeoff, but once in the air it flew beautifully. I liked the way it flew, but not the takeoff. Mine was the yellow version as seen on a 3view with the kit.
