Top-Flite 1/5th F4U Corsair ARF Group Build and modification thread
#726
Did a search and did not find this is issue. Did anyone have issues with their ailerons not deflecting fully down. Mine only deflects verrrrrrrrry little compared to the up deflection and compared to what I am used to seeing in ailerons on any plane. Seem like some extra wood is hitting. Might need to remove the monokote and flatten out the wood at and angle like the rest of the ailerons at the hinges. Will take a picture when I get home.

Lifer, I did think of using the differential option but the little voice in my head kept saying no, fix the problem, so I did, Lol. The fix to sand the leading edges and replace the Monokote strips on the ailerons only took 45 minutes each. The PITA fix wasn't as bad as I first thought it would be.

The big mistake of not checking that all items are packed in the box when one purchases an ARF instead of waiting 18 months before opening the box. The first problem encountered was the pre-hinged ailerons, only 1/8" down deflection. I fixed that problem without much difficulty. Unfortunately I have a more critical issue, the two carbon fiber tubes that slide into the center wing section and outer wing panels that help hold the outer wing panels from departing in flight are missing from the box. This is a real PITA trying to find suitable tubing to replace the stock carbon fiber tubes.

They did that because the topflite models were taking away from H9 ARF sales.
I compared the TF 1/5 mustang side by side with the H9. Ended up with the H9 thinking it would give me more of the pkane budget for the engine mods I wanted to do. Will I be happy in the end...reasonably so, but, in retrospect, if I were to think about it again, I should have dropped the extra cash and gotten the TF.
My life would have been eaiser I think...

I have no idea how many flights on mine but it’s 12 years old and has had 4 engines! I’ve considered retiring it, glassing it and making a mold from it. Love the way it flies and has been old reliable all this time. I’ve flown the H9 Corsair and while it’s nice it’s too heavy. The TF is a good sport scale Corsair for all around use off grass or paved runway and low to high winds.
Mods I like to see on this plane: Scale Flaps, Scale Tail Gear and Doors, Folding Wings (been done by Earl A. with a custom designed fiberglass mechanism)
Engines: DLE 55RA, Saito FG84, DLE 61, DLE 65
Telemetry: Temp and RPM
Robart Gear - 100% reliable air system and mechanics - add a few drops of silicone oil each season to the cylinders, use large and medium air tanks together for more volume = reliability
Last flight at our club field Summer 2020 before this turned into a gravel pit…

Trying different engines. I was offered the FG84 so I had to see that one for sure. The cowl was a mod on the H9 cowl and it worked but the AUW was too much for this plane making it critical when landing. The 61 was just not right but in hindsight I think it was just the oil I used which had castor. The 65 is a beast and a perfect balance, more power than the 55RA and still light. The only issue I’m having is the vibration making the cowl loose so I’m working on the cowl mounts. The prop is balanced and runs true so I’m wondering if it’s just the engine. I checked the crank bolt to see if it runs true and it’s fine so it could be a characteristic of this engine. Going back to the 55RA isn’t an option now after flying with this much performance but the 55RA and this size war bird is a great combo.

I dont suppose that that you would part with that fine looking center wing section. By the way i've had a dle 55 side exhaust in mine for 642 flights.

I’ve got the FG60 in a Hellcat and it’s a pretty sweet engine for that plane, feels like a very good match. In the TF FW I wonder if it’s under powered? I wish I kept my TF FW ARF but sold it new in box instead. I had an issue with the FG60 changing over to a non castor oil blend. I tried the Klotz oil with castor and changed over to the full synthetic so in the process the carb setting wasn’t right and the engine quit in flight. I don’t recommend the castor blend in these RC gas engines, they don’t run right, it’s much better to run full synthetic.
