Hello , I have posted before on other topics, Inreacentlly purchased a OFNA GTP2 nitro and upgraded it with a 4 shue clutch, hitec hi torque titanium gear coreless servos from a 700 heli swash plate, an LRP.32 engine and changed the spur gear and clutch bell pinions. Since the Lrp engine generates a tremendous torque and has a not so hi max rpm (around 33,500 max accirding to lrp) the top speed was around 60mph, I was having problems with the car on departure since the tires would slip because of the engine torque . I decided to change the spur and cluthc bell gears to increase top speed, the original gear setup was
Clutch/spur
14/49 1st gear
18/45 2nd gear
I changed it to
Clutch/spur
16/49 1st
21/44 2nd
It has done some effect while departing and kills some torque out of the hole, but now, when shifting to 2nd gear the engine dies, I have tried getting to speed little by little to the shifting point so that the engine is reving hi rpm but still shuts off. It makes a particular sound like a slow motion cassette playing on a walkman, the engine was was broken in and has runed about a bit more than half a gallon. The local hobby shop told me that could be the engine running too lean at top speed but I dont really know, I asked him if the gear teeth reduction was too agressive and the engine couldnt handle it, but he said if that was the case the car would just run slower until the engine could acelerate and keep up. Any help would be greatlly apreciated since I am kind of new to thes! Thank you!
