Ibcinyourc has great prices on dle engines and the best personalized service Ive ever had. I did not have a good experience with valley view and will not do business with them again. tower is like wallmart, don't expect too much with service and you won't be disappointed

This pic was taken in Peking today.

First one we've seen with a pitts.

THe OS 55cc gas wasn't great??
Didn't know it had any problems...'

Dle has had it's issues as well...
But the cheap price, guys forget about it??

I am not swayed either way...
I have DLE 20cc but haven't run it yet...so can't comment..

I think os should have tried to convert there glow engines...
The 1.20 could have been easilly changed (carb and needle bearing)
before vesting all the money into the 55gt..

I guess Japan needs gas engine's too!...
Probly more reasonable there, than compared to the DA's and sysas...

I have 2 DLE-20's they both run great. The OS GT-55 that I had drooled gas into the cowling, and when it did run, did so mostly on a DLE-30 ignition. I replaced it with a DA-60, and it is lighter, more powerful, and starts and runs great.

I think OS is watching and they are awear of the issues some modelers have had with the 55, which led them to make a few changes. The front mounted carb probably wasn't a good idea. I guess they were thinking along the lines of a glow? With the GT33, the carb is at the rear..... The choke feature is also cool. We'll have to wait for the specs. Hopefully it's powerful, doesn't weigh much and very reliable.

What is different about the choke?

Have a look at the video coverage from the 2011 Toledo Show. ;-)

Someone tell me what that has to do with airplanes or Toledo

$369 with free shipping for tower club members.
$50 off $300 coupons come in very handy, coupled with free ground shipping or $3 priority mail shipping.

I should have said I love how the choke is a part of the casing.
