I've got one of these which is only partially assembled , one of the other guys on here,crasharama built one and flew it with a jett50, but on his fourth flight the elevator control horn sheared off..sort of turned it into a lawn dart..luckily he mentioned this before I got to build mine so now I'm just waiting on some Robart horns..other than that it seems to be fairly good quality although I cant say much about the flight envelope yet!!! unfortunate side, there is no provision for retracts...sure would be sweet to clean this bird up a bit.the only other hiccup is the engine mount that come out on our versions is a bit small..only measures 30mm i think thats about 1 and 1/16 " so a bit small for a .46 upward size engine but who knows maybe they fixed that since its been released in the States.

I had a Jett 90L in a Krangke F20, but the top end was not there. Flew well and relatively fast, but just not fast enough. Needed retracts for sure, but the fakee engine openings and overall dirty airframe made it a dog considering the power. Have great interest in your upcoming flight experience and your thoughts. Are you sure you can't stuff retracts in yours? Would appreciate knowing outcome, and power used. Thanks

I missed this coming in to Tower. Interesting. Should be a popular plane.

There are a few guys over in Australia and the eastern rim flying them that I know of.

Four I am aware of have SJ-50 engines, and one other has a 60L. Dub also shipped a 60LX not long ago to NZ destine for a Phx F-20.

From all reports apparently the plane itself flys well, and the kit goes together about like other ARFS. Fixed gear - it is pretty quick, but it is not going to go "really" fast if you have the gear down - the strut/wheel drag is incredible. For most people, this plane is quick enough.

Keep in mind.... it is an ARF - somebody built MOST of it for you - and it is VERY worth while reviewing certain structural elements and carefully considering each control surface, control horn and linkage with respect to the engine you install in it. Take the time to seal all of the control surface gaps too.

Also as HaveBlue noted, the engine mount appears to be somewhat narrow - maybe its set up better for an OS .46 size now.

Anyone knows the true winspan and length of this plane?? Tower has incorrect measurements posted. I wonder if there is enough room to slap a OS91FX in the nose. I have a spare motor that needs to go in a prop jet. I want to reserve my Jett90 for the Cermark F16 I'm putting together. 50 size motor is too weak for plane with span 56". My Kangke F20 with a 50 motor has only 48" span.

Don't let the wing span fool ya.

Reports I have from folks tell me its got pleanty of power with a .50 up front.

Without retracts, its not going to hit 140 mph anyway.

I think Haveblue on here has one of these too ?

Reports I have on the engine installation, were that the mount was designed for an old-style OS.40 FSR engine - beams are actually a tiny bit narrow for the OS.50 or Jett-50 engine. Easy to fix though. Im not sure if the Tower import version has this feature updated.

I just got a tape measure out and those measurements are correct, its 51" from the tail end to the motor, so this doesnt include lenght to the spinner so it will be a tad longer and one wing panel is 28 1/4 " ..but it is very light, I havent flown mine yet..but I have no doubt that it will fly very well on a .50 , I'm using a jett46 on mine and I'm confident that will do the trick although as bob27s has mentioned without further mods like installing retracts( and there are no provisions to do so) its not going to be super fast.. as for installing the 90, I had the same idea before I bought it.. when I got it, I soon changed my mind about putting my Jett 90l in it.. I'm not saying it cant be done but to me it would be to extensive to modify the front to fit the large engine and I think it would need some serious re-enforcement to cope with the extra load, not to mention balancing issue's

it's not a bad little plane , but IMO I would choose a different F20 to put retracts and a large engine in.. I sort of look at it like this..whats the point of getting an ARF then having to perform surgery rebuild half of it and then hope it all holds up to the improvements..I would get something more accommodating to what you want the final result to be

.but then again what do I know!!!???!!!

Hi guys,

Sorry I haven't got back to you but have been in Montreal for work for the last month & didn't see this 1 come up.

The photos that Bob 27s posted was my F20, but she is no more unfortunately.

If you are serious about the 20, make sure you replace the control horns supplied in the kit as this is what let go on mine. It sheared off where it "T's" to the mounting plate, with the aweful sound of elevator flutter just before a large bang.........& nothing left. The elevator control linkage is a funny angle, & I think this may have something to do with it as well. As Bob said I had to reshape the engine mount to fit the SJ 50 into the mount as well.

The model itself was well put together but just had a few little things that I would change now in hindsight.

I just ordered mine this morning from Tower Hobbies. It was the first time I seen it in their flyer and had to have it because I don't have a jet yet, and I do own a Phoenix Models Sukhoi 31 which is an EXTREMELY great ARF for the price (read my review about it on R/C U
