Hi Everyone, I am the newest member P510851. I have a question for you. I have a skyshark 82" p-40 and wanted a good retract for it so I ordered the Robart 150 rotating retracts. are they ok or are there problems with the fit?
Thanks
Tony

RBEAN.
So far so good.they are very light out of the box but of course by doing scale mods will add more weight but that hasnt upset it at all.i had a lot of problems finding a large size p40 in ozz and the cmpro was what i ended up with.its been a good airframe to try some scale mods on and is performing well.

I'm really having issues with my engine. 6 flights and the last 3 have been dead stick. I made a bad decision to extend the gear instead of belly landing in some rough ground and knocked both gear out of the wing. No other damage and easily repairable. When the engine is running right the plane is a dream to fly.

I feel your pain. I make the same mistake with my Kyosho P-40 on a dead stick. I was on downwind but I thought I had enough energy (speed and altitude) to make a turn for the runway. I extended the gear, initiated a bank and the airplane dropped like a rock. Didn't rip the gear out but bent both struts flat against the wing. If I would have kept the gear up everything would have been fine.

My problem with the engine (Saito 65) is that is was overheating inside the cowl.

Been making some headway on the TF 1/7 electric conversion:


Here are the readings from my bench test:

Power 60:
15x7 3 blade Master Airscrew prop 6920 RPM at 36Amps at 22.2 volts
15x7 3 blade Master Airscrew prop 7700 RPM at 45Amps at 25.0 volts
14x9 3 blade Master Airscrew prop 7540 RPM at 43Amps at 23.0 volts

Power 90:
16x8 3 blade Master Airscrew prop 5950 RPM at 40Amps at 23.0 volts
16x10 3 blade Master Airscrew prop 5920 RPM at 37Amps at 23.0 volts

As a comparison, these are pushing the numbers I was getting with a DLE-20 gas.

My first flight was with a TF P-47 ARF at around 9 pounds with the Power 60 with the 15x7 3 blade Master Airscrew prop. Flight was clean with a scale speed, not overpowered, but not underpowered. The 14x9 should add some speed, but no flights with it yet.

We did decide to move up to the 90 combination for the TF 1/7 P-40 kit built which will be in the 12 pound range. Not airworthy yet, but getting closer.

At what point in the flight are you having engine quit? I had some issues with mine quiting only a couple of minutes into the flight and it turned out to be overheating. I added some baffling and it really helped.

I have baffling around the engine and it runs cool. The engine would run strong on the ground for as long as you wanted, but would slowly lose power and quit after only a minute or so in the air. I may have fixed the problem...I checked the filter screen in the carb and it was nasty looking! Replaced it with a new one and will see if that fixed it. My DLE 20 had the same problem earlier this year and cleaning the screen fixed it.

That was going to be my next suggestion as Ihad a small piece of metel from the factory that got under the float needle and kept flooding the engine. Sounds like you have it down now.

On the possible DLE 20 cooling problems, what I did was duct air from the scoop above the spinner to the area of the carb to prevent the carb getting too hot from the pitts muffler just under the carb and causing vapor lock. I used a flexable plastic tube. The air flow was from above the carb, down past the carb and then the muffler and out the rear of the cowling keeping the muffler heat away from the carb. It works, no problems even in the hottest weather at full power.

Great idea! Inever thought about the pitts muffler effecting the rear carb. Learn something new all the time here.

We finally figured out why my engine was quitting in flight. The fuel tank was sliding aft and kinking the fuel line and shutting off fuel flow. The engine is back to running great.

 I have two of these, a CMP, with an OS 160, 3 blade prop, mechanical retracts which are kinda flimsy. (I'll get a better pair at swap meets this winter, I hope), but it flies straight as an arrow, will do anything! Lands kinda hot, but it's a war bird! Second one is a VQ 60 size with a magnum 4 stroke, on board glow & mechanical retratcts. 
Rotating retracts are hard to keep workin, especially when u land like I do!! I have tried the "cheap"  ($10 -15, + shipping) oleo struts from ChinaProducts (bidPro), they help & hold up fair.. metric set screws won't stay tight, strip, loose out, etc. but the struts haven't bent yet at least. I mount all landing gear with nylon #6 screws so as to shear off & so far they have saved wing rebuild!!

I have made more progress on the P-40 over the weekend and this evening.

During this electric conversion I attempted several powerplant mounting ideas, and after deciding on an engine box I returned to one of my previous plans to use standoffs.

Photo 1, 2, 3, and 4 show the remains of an engine box reduced to template wood for locating the engine mount bolt pattern and centering the spinner bulkhead.

Once the template position was confirmed as seen in Photo 4, I drilled the firewall for the standoff hardware as seen in Photo 5.

Photos 6 and 7 are the results of the above. I use large area washers on both sides of the firewall, and both sides if the engine mount’s ears to spread out the operational loads, all secured with self locking nuts on both sides of all mounting locations.

All totaled I have a lighter set-up and an adjustable mounting system for thrust.

Photos 8 and 9 is where I left off with some applied paint.

Mike Early, I have a VQ P-40 electric conversion. What retracts did you believe were the best in your VQ pP-40's? Has anyone have any experience with Hobbyking 90 degree rotating rertacts with the 5mm dia wire strut? The mechanical retracts just have too much play inthem and are kinda a pain in the dupa to set up. I'm kinda partial to the new breed of electric retracts.

Update on the E-Flight Power 60 1/7 TF P-40 electric conversion.

This plane started as a TF 1/7 Kit, but my friend and his son fly all electric, so we went with the Power 90.

Paint is going on the bird as you can see in the photos.

Does anyone know where I can purchase some 1/7 scale vinyl markings for the Flying Tigers scheme?

I used Century Jets in all my corsairs and p-40s because I have a few sets. I've had to learn how to tweak them and adjust them. I've also learned how to fly heavy warbirds on them. Obviously the future of retracts is electric. I have used retracts from hobbyking and hobbypartz with success. I will try the E-Flites rotating retracts one day and add some oleos, Eventually I expect them release a 60-120 size set of rotating retracts.

Give me a day to look, and I may have a set for your sons plane....free! Heck I've even got a cockpit kit completed Ill throw in. I lost mine during a move from Hawaii, it was not finished yet so I still have the decals.
