In search for additional performance and speed I’ve reached 81-83mph with the Corsair so far. I think I stick with this level as it seems to be the sweet spot for the reinforced airframe and anything more powerful is asking for trouble. Radar gun information is on my post HERE.
After starting the motor upgrades on the Corsair I am on my 3rd new motor after trying several different options. What I settled on for the moment is the inexpensive MonsterPower15 available (hobbypartz) from a US distributor via Hong Kong. Just to recap my path of upgrades I’ll list them below.
REINFORCE YOUR CORSAIR IF YOU PLAN TO UPGRADE YOUR MOTOR
Servos were upgraded to Metal Gear T-Pro MG90 9gram
With the addition of the first motor upgrade and hard flying the weak point then became the wing and other control surfaces such as the horizontal stabilizer and the vertical stabilizer. These areas were fixed with raw Carbon Fiber Tow which was laid down with an epoxy mix on both sides of the surface. I used CSTsales for my source of Carbon Tow and purchased several different strand count rolls. I used the 50k Tow for the wings. As the Tow is very flexible you can follow the gull wing design of the wing very well. On future reinforcing I will be using the solder iron or dremel to trench a shallow well and embed the Carbon into the wing. The exact approach I used for my Stryker Wing build (here). I also added new metal gear aileron servos. I was going to use the Hitec HS-85mg that I use in my Stryker but picked up (2) PKZ1090 and added extensions. The stock nylon servos suck as everyone who owns a Corsair can attest.
Now granted my Corsair has lost her looks over the years but that’s the point I have flying the heck out of it for years and repairs along the way add personality lol.
Conclusion is the 3536c wasn’t proving enough speed for my expecations.
The MonsterPower 25 was heavy and it’s low KV required a large prop and even then wasn’t delivering the speed and results however the torque and vertical were fun.
The MonsterPower 15 so far has been the sweet spot with a 4s and 12″ or larger prop. I have a radar gun that we will use on it and look forward to posting results.
