Default questions regarding QQ python

Hi Rezagh

I have a QQ python with a 3W 110b2 CS 12.8 hp.
The question refers to the engine Canister with D70 mm.
I have problems with having them in the channel to the Canister. There is no more than 1-2mm on each side.
3W said the engine was not tested with D55 mm Canister, then 3W discouraged me to buy the D55 mm Canister.
I wonder if there will be too hot in the channel.
Which servos should I use? I intend to use HiTec HS-5985 as the servos . Is this okay?
What propeller should I use when it should not exceed 94 db in the club? A 2 blade or 3 blade propeller?

Best regards

Tommy

Tommy,

Servos will be OK! As for the dba nd propeller you need to experiment that. 3 bladed props with higher pitch and carbon fiber are quieter!

Does two 70mm diamter can fit in the tunnel?

Thank you,
Reza

Hi Rezagh

Thanks for the quick reply.
In these pictures you can see what I have done. There is not much space.

Best regards

If it doesn't expand that they touch each other, you should be fine but keep an eye on it especially if you are flying 72mhz and not 2.4. another problem that I just saw is that the cans are sitting on the balsa floor and there is no silicone around them, I am afraid you can damage the frame or even have small burnt spots on the balsa. Those cans are big for that tunnel! I wish you could use smaller cans.
